Title: On Sandokhan definitions of the Sagnac and Coriolis Effects
Post by: rabinoz on August 26, 2019, 09:38:06 PM
This is simply a reply to a post by Sandokhan in the thread: Flat Earth General   Re: how to know the altitude of a DirecTV satelite where it is quite off-topic.

Georges Sagnac derived the CORIOLIS EFFECT formula, which features the AREA.
Look, YOU cannot arbitrarily define what is Coriolis Effect and what is Sagnac Effect. That has been decided long before YOU came on the scene!

No! Georges Sagnac derived the SAGNAC EFFECT formula, which bears HIS name and features the AREA.

Regarding the Proof for the Existence of a Luminiferous Ether Using a Rotating Inteferometer Experiment by Georges Sagnac (http://zelmanov.ptep-online.com/papers/zj-2008-08.pdf)
Abstract: This is English translation of Georges Sagnac’s second paper, which presents his “rotating interferometer experiment” where
the phenomenon known as the Sagnac effect manifests itself. This paper was originally published, in French, as: Sur la preuve de la realite de l’ether lumineux par l’experience de l’interferographe tournant. Note de G. Sagnac, presentee par E. Bouty. Comptes rendus, 1913, tome 157, pages 1410 –1413. Translated from the French in 2008 by William Lonc, Canada. The Editor of The Abraham Zelmanov Journal thanks William Lonc for this effort, and also Ioannis Haranas, Canada, for assistance.
Special thanks go to the National Library of France and Nadege Danet in person for the permission to reproduce the originally Sagnac paper in English.

Quote from: sandokhan
The definition of the Sagnac effect is applied to a closed loop (either circular or a uniform path).
Loop = a structure, series, or process, the end of which is connected to the beginning.
Thus, from a mathematical point of view, Michelson did not derive the Sagnac effect formula at all, since he compared two open segments, and not two loops.
No! Whatever YOU CLAIM, Michelson derived the Sagnac effect formula!

How can you ever claim that this is "two open segments, and not two loops"?

The definition of the Sagnac effect.
Using the correct definition, we recover not only the error-free formula, but also the precise velocity addition terms.
For the Coriolis effect, one has a formula which is proportional to the area; only the phase differences of EACH SIDE are being compared, and not the continuous paths.
No! The Coriolis effect is completely different and is not related to area in the slightest! (https://wikimedia.org/api/rest_v1/media/math/render/svg/e4eb6b9a1018b1ffbdf7bdf9883a8b4e8bd7f8fb)

The theory was originally developed by Gaspard-Gustave de Coriolis and applied to water-wheels. His original paper is the second in:

Quote from: sandokhan
For the Sagnac effect, one has a formula which is proportional to the velocity of the light beam; the entire continuous clockwise path is being compared to the other continuous counterclockwise path exactly as required by the definition of the Sagnac effect.

Experimentally, the Michelson-Gale test was a closed loop, but not mathematically. Michelson treated mathematically each of the longer sides/arms of the interferometer as a separate entity: no closed loop was formed at all. Therefore the mathematical description put forth by Michelson has nothing to do with the correct definition of the Sagnac effect (two pulses of light are sent in opposite direction around a closed loop) (either circular or a single uniform path). By treating each side/arm separately, Michelson was describing and analyzing the Coriolis effect, not the Sagnac effect.

Loop = a structure, series, or process, the end of which is connected to the beginning.
No! The Sagnac loop can be any shape at all! And, of course, you would analyse any straight edged loop one edge at a time! Whyever NOT?

Quote from: sandokhan
Connecting the two sides through a single mathematical description closes the loop; treating each side separately does not. The Sagnac effect requires, by definition, a structure, the end of which is connected to the beginning.
No! The Sagnac loop can be any shape at all! And, of course, you would analyse any straight edged loop one edge at a time! Whyever NOT?

Quote from: sandokhan
HERE IS THE DEFINITION OF THE SAGNAC EFFECT:

Two pulses of light sent in opposite direction around a closed loop (either circular or a single uniform path), while the interferometer is being rotated.
So?
Quote from: sandokhan
Loop = a structure, series, or process, the end of which is connected to the beginning.

A single continuous pulse A > B > C > D > A, while the other one, A > D > C > B > A is in the opposite direction, and has the negative sign.

Let's ignore your derivation and use the result from what appears to be the source of your diagram: The Michelson-Gale Experiment by Doug Marett (2010) (http://www.conspiracyoflight.com/Michelson-Gale/Michelson-Gale.html)

Look at this from what appears to be the source of your diagram:
Quote from: Doug Marett
Conspiracy of Light, The Michelson-Gale Experiment (http://www.conspiracyoflight.com/Michelson-Gale/Michelson-Gale.html)
In refining his argument, he proposed that it was not necessary for the light to go all the way around the globe - since there should be a velocity difference for any closed path rotating on the surface of the earth. He presented the following equation to calculate the time difference expected, using the shift in the interference fringes when the two beams overlap at the detector as a measure of the time difference:
Fig.1:
(http://www.conspiracyoflight.com/Michelson-Gale/MangG1.jpg)
where:  Vo = the tangential velocity of the earth's rotation at the equator (465m/s)
              A = the area of the circular path
              R = the radius of the earth (6371000 m)
              c = speed of light (3E8 m/s)
              f = the latitude in degrees where the experiment is conducted.
              l = wavelength of the light
And those 2's should be 4's because even Michelson didn't initially get it quite right and it was corrected by Silberstein:
Quote from: Doug Marett
   The experiment remained in abeyance for several years, until Silberstein published a paper in 1921 on the theory of light propagation in rotating systems. In this article, Silberstein discusses Michelson's proposed experiment and through calculations of his own demonstrated that the time difference expected in such an experiment would be double what Michelson suggested.

Quote from: sandokhan
Dr. Ludwik Silberstein, a physicist on the same level with Einstein and Michelson, partially inspired and supported the Michelson-Gale experiment.

In 1921, Dr. Silberstein proposed that the Sagnac effect, as it relates to the rotation of the Earth or to the effect of the ether drift, must be explained in terms of the Coriolis effect: the direct action of Coriolis forces on counterpropagating waves.
<< Let's ignore all that for the moment - I simply do not have the time! >>

He proved that the real cause of the phenomenon measured by Georges Sagnac was the CORIOLIS FORCE EFFECT.
No! Dr. Ludwik Silberstein did not "prove that the real cause of the phenomenon measured by Georges Sagnac was the CORIOLIS FORCE EFFECT."
He showed that the light paths deviated from straight lines due to the Coriolis effect but by a negligible amount and so that was completely left out of his final result!

Malykin and Pozdnyakova do say:
Quote from: Grigorii B. Malykin and Vera I. Pozdnyakova
Siberstein [798, 799] suggested an explanation of the Sagnac effect based on the direct consideration of effect of the Sagnac forces on the counterpropagating waves. . . . . The areas of the triangles are different."
Now, while "the areas of the triangles are different" Dr Siberstein had previously shown "Thus, even for a ≈ 10 or 20 km the difference would certainly be too small to be measured directly.
So Dr Silberstein certainly does not "derive the Coriolis effect" and on the contrary, he shows that its effect is "certainly be too small to be measured directly."

And again: Malykin and Pozdnyakova say:

The formula derived by Dr. Silberstein, peer reviewed in the IOP article, and described by the author as the "effect of the Coriolis forces" is this:
dt = 4ωA/c^2
Excuse me but is it described by the author as the "effect of the Coriolis forces"? Silberstein explicitly neglects the "effect of the Coriolis forces"!

So dt = 4ωA/c^2 is simply the Sagnac Delay, nothing more!

Quote from: sandokhan
Here is the Maraner-Zendri formula:
(https://www.dropbox.com/s/ov40a15kkr8uogv/General%20relativistic%20Sagnac%20formula%20revised%2C%20Maraner%2C%20Zendri%20-%20eqn%20%2817%29.png?dl=1)

What Maraner and Zendri did is to derive the CORIOLIS EFFECT formula with relativistic corrections which are dependent on the center of rotation, and NOT the SAGNAC EFFECT.
No, they did not "derive the CORIOLIS EFFECT formula" but they did "derive the Sagnac Effect formula with relativistic corrections which are dependent on the center of rotation".

And that "dependence on the center of rotation" is only part of the relativistic corrects and in any case he showed that in practical cases the relativistic corrections are negligible.

If those corrections are neglected it reduces to the usual Sagnac expression which is independent of the shape of the loop and the centre of rotation.

Quote from: sandokhan
They used the SAME derivation as did Michelson based on a comparison of two sides, AND NOT THE TWO LOOPS as required by the definition of the Sagnac error, a huge error on their part.
Nope, that's just your incorrect interpretation.

Quote from: sandokhan
For the uninformed RE: here is the correct definition of the Sagnac effect.

https://www.mathpages.com/rr/s2-07/2-07.htm
You mean the one that goes on to say:
Quote
2.7  The Sagnac Effect (https://www.mathpages.com/rr/s2-07/2-07.htm)
This phenomenon applies to any closed loop, not necessarily circular. For example, suppose a beam of light is split by a half-silvered mirror into two beams, and those beams are directed in a square path around a set of mirrors in opposite directions as shown below.
(https://www.mathpages.com/rr/s2-07/2-07_files/image003.gif)
Just as in the case of the circular loop, if the apparatus is unaccelerated, the two beams will travel equal distances around the loop, and arrive at the detector simultaneously and in phase. However, if the entire device (including source and detector) is rotating, the beam traveling around the loop in the direction of rotation will have farther to go than the beam traveling counter to the direction of rotation, because during the period of travel the mirrors and detector will all move (slightly) toward the counter-rotating beam and away from the co-rotating beam. Consequently the beams will reach the detector at slightly different times, and slightly out of phase, producing optical interference "fringes" that can be observed and measured.

Quote from: sandokhan
THE SAGNAC EFFECT DOES NOT REQUIRE AN AREA, only the CORIOLIS EFFECT is proportional to an area.
No, you have never shown that "THE SAGNAC EFFECT DOES NOT REQUIRE AN AREA" and the CORIOLIS EFFECT is quite unrelated to an area.

Go and read what the Coriolis Force is! Here is the expression for it (https://www.real-world-physics-problems.com/images/coriolis_force_3.png)
Title: Re: On Sandokhan definitions of the Sagnac and Coriolis Effects
Post by: sandokhan on August 26, 2019, 11:07:53 PM
The rotational and the orbital CORIOLIS EFFECT formulas were derived for the first time in 1904 by A. Michelson, and they feature AN AREA:

http://www.conspiracyoflight.com/Michelson-Gale/Michelson_1904.pdf

Georges Sagnac derived THE SAME FORMULA, featuring an area, the CORIOLIS EFFECT formula.

The original papers published by G. Sagnac (The Luminiferous Ether is Detected as a Wind Effect Relative to the Ether Using a Uniformly Rotating Interferometer):

http://zelmanov.ptep-online.com/papers/zj-2008-07.pdf

http://zelmanov.ptep-online.com/papers/zj-2008-08.pdf

In 1913, Georges Sagnac measured ONLY the Coriolis effect, and not the true Sagnac effect (proportional to the linear velocity and radius of rotation).

Here is the shape of the interferometer used by Sagnac:

(https://ars.els-cdn.com/content/image/1-s2.0-S1631070517300907-gr001.jpg)


Is there a way to clearly distinguish between the formulas required for an irregularly shaped interferometer and a symmetrically shaped interferometer?

Yes, there is: using graduate level differential geometry.

Please read:

https://arxiv.org/pdf/gr-qc/0103091.pdf

Coriolis Force and Sagnac Effect

Because of acting of gravity-like Coriolis force the trajectories of co- and anti-rotating photons have different radii in the rotating reference frame, while in the case of the equal radius the effective gravitational potentials for the photons have to be different.

(http://image.ibb.co/cUTCax/cor1.jpg)
(http://image.ibb.co/jGVx8H/cor2.jpg)

An interferometer with DIFFERENT RADII (located away from the center of rotation) will manifest the Coriolis force in the form of a phase shift 4AΩ/c^2.

Different sets of radii and the center of rotation do not coincide with the geometrical center of the interferometer.

That is why Sagnac had to use the formula which features the area and the angular velocity: he only measured the CORIOLIS EFFECT.

Even if the shape of the interferometer is made to look more symmetrical, there are still two different radii to deal with:

(https://image.ibb.co/kisGKd/mgrot5.jpg)


This is the formula derived by G. Sagnac:

4AΩ/c^2.



THIS IS THE CORIOLIS EFFECT FORMULA.

Here is the precise proof, peer-reviewed in an IOP article.

THIS IS AN IOP ARTICLE, one of the most comprehensive papers on the Sagnac effect ever published.

Here is reference #27:


(https://image.ibb.co/eCKok9/sil3.jpg)



http://www.conspiracyoflight.com/Michelson-Gale/Silberstein.pdf

The formula derived by Dr. Silberstein, peer reviewed in the IOP article, and described by the author as the "effect of the Coriolis forces" is this:

dt = 4ωA/c^2


Here is a direct derivation of the same formula using only the Coriolis force:

https://www.ias.ac.in/article/fulltext/pram/087/05/0071

The derivation has NO LOOPS at all.

Just a comparison of two sides.



Here is how Dr. Silberstein's CORIOLIS EFFECT formula was derived:

The propagation of light in rotating systems, Journal of the Optical Society of America, vol. V, number 4, 1921

He proved that the real cause of the phenomenon measured by Georges Sagnac was the CORIOLIS FORCE EFFECT.

(https://image.ibb.co/bZAaCy/mgrot4.jpg)

Dr. Silberstein proved that the effect measured by Sagnac is A PHYSICAL EFFECT, a deflection/inflection of the light beams due to the CORIOLIS FORCE.

In 1922, he extended the definition used in his 1921 paper on the nature of the rays arriving from the collimator:

http://gsjournal.net/Science-Journals/Historical%20Papers-Mechanics%20/%20Electrodynamics/Download/2645

Dr. Ludwik Silberstein, a physicist on the same level with Einstein and Michelson, partially inspired and supported the Michelson-Gale experiment.

In 1921, Dr. Silberstein proposed that the Sagnac effect, as it relates to the rotation of the Earth or to the effect of the ether drift, must be explained in terms of the Coriolis effect: the direct action of Coriolis forces on counterpropagating waves.

http://www.conspiracyoflight.com/Michelson-Gale/Silberstein.pdf

The propagation of light in rotating systems, Journal of the Optical Society of America, vol. V, number 4, 1921

Dr. Silberstein developed the formula published by A. Michelson using very precise details, not to be found anywhere else.

He uses the expression kω for the angular velocity, where k is the aether drag factor.

He proves that the formula for the Coriolis effect on the light beams is:

dt = 2ωσ/c2

Then, Dr. Silberstein analyzes the area σ and proves that it is actually a SUM of two other areas (page 300 of the paper, page 10 of the pdf document).

The effect of the Coriolis force upon the interferometer will be to create a convex and a concave shape of the areas: σ1 and σ2.

The sum of these two areas is replaced by 2A and this is how the final formula achieves its final form:

dt = 4ωA/c2

A = σ1 + σ2

That is, the CORIOLIS EFFECT upon the light beams is totally related to the closed contour area.



Here are the DEFINITIONS USED BY MODERN SCIENCE TO DESCRIBE THE SAGNAC EFFECT:

https://www.mathpages.com/rr/s2-07/2-07.htm

If two pulses of light are sent in opposite directions around a stationary circular loop of radius R, they will travel the same inertial distance at the same speed, so they will arrive at the end point simultaneously.

http://www.cleonis.nl/physics/phys256/sagnac.php

Essential in the Sagnac effect is that a loop is closed.

http://www.einsteins-theory-of-relativity-4engineers.com/sagnac-effect.html

The Sagnac effect is observed when coherent light travels around a closed loop in opposite directions and the phases of the two signals are compared at a detector.



THE SAGNAC EFFECT DOES NOT REQUIRE AN AREA, only the CORIOLIS EFFECT is proportional to an area.



Michelson and Gale COMPARED TWO SIDES ONLY, not any loops at all:

(https://image.ibb.co/h0EPSA/fa.jpg)

The final formula used by Michelson features an AREA: it is the CORIOLIS EFFECT formula.



Using a phase-conjugate mirror, for the first time in 1986, Professor Yeh was able to derive the TRUE SAGNAC FORMULA which is proportional to the velocity of the light beams.

The Coriolis effect is a physical effect upon the light beams: it is proportional to the area of the interferometer. It is a comparison of two sides.

The Sagnac effect is an electromagnetic effect upon the velocities of the light beams: it is proportional to the radius of rotation. It is a comparison of two loops.

Two different phenomena require two very different formulas.


My SAGNAC EFFECT formula proven and experimentally fully established at the highest possible level of science.



Let us now compare the two derivations, using two loops (Sagnac effect) and two sides (Coriolis effect):

(http://www.conspiracyoflight.com/Michelson-Gale_webapp/image002.png)

Point A is located at the detector
Point B is in the bottom right corner
Point C is in the upper right corner
Point D is in the upper left corner

l1 is the upper arm.
l2 is the lower arm.

Here is the most important part of the derivation of the full/global Sagnac effect for an interferometer located away from the center of rotation.

A > B > C > D > A is a continuous counterclockwise path, a negative sign -

A > D > C > B > A is a continuous clockwise path, a positive sign +

The Sagnac phase difference for the clockwise path has a positive sign.

The Sagnac phase difference for the counterclockwise has a negative sign.


Sagnac phase components for the A > D > C > B > A path (clockwise path):

l1/(c - v1)

-l2/(c + v2)

Sagnac phase components for the A > B > C > D > A path (counterclockwise path):

l2/(c - v2)

-l1/(c + v1)


For the single continuous clockwise path we add the components:

l1/(c - v1) - l2/(c + v2)

For the single continuous counterclockwise path we add the components:

l2/(c - v2) - l1/(c + v1)


The net phase difference will be (let us remember that the counterclockwise phase difference has a negative sign attached to it, that is why the substraction of the phase differences becomes an addition):

{l1/(c - v1) - l2/(c + v2)} - (-){l2/(c - v2) - l1/(c + v1)} = {l1/(c - v1) - l2/(c + v2)} + {l2/(c - v2) - l1/(c + v1)}

Rearranging terms:

l1/(c - v1) - l1/(c + v1) + {l2/(c - v2) - l2/(c + v2)} =

2(v1l1 + v2l2)/c2

Exactly the formula obtained by Professor Yeh:

φ = -2(φ2 - φ1) = 4π(R1L1 + R2L2)Ω/λc = 4π(V1L1 + V2L2)/λc

Since Δφ = 2πc/λ x Δt, Δt = 2(R1L1 + R2L2)Ω/c2 = 2(V1L1 + V2L2)/c2

CORRECT SAGNAC FORMULA:

2(V1L1 + V2L2)/c2

Self-pumped phase-conjugate fiber-optic gyro, I. McMichael, P. Yeh, Optics Letters 11(10):686-8 · November 1986 

http://www.dtic.mil/dtic/tr/fulltext/u2/a170203.pdf (appendix 5.1)


This is how the correct Sagnac formula is derived: we have single continuous clockwise path, and a single continuous counterclockwise path.

If we desire the Coriolis effect, we simply substract as follows:

dt = l1/(c - v1) - l1/(c + v1) - (l2/(c - v2) - l2/(c + v2))

Of course, by proceeding as in the usual manner for a Sagnac phase shift formula for an interferometer whose center of rotation coincides with its geometrical center, we obtain:

2v1l1/(c2 - v21) - 2v2l2/(c2 - v22)

l = l1 = l2

2l[(v1 - v2)]/c2

2lΩ[(R1 - R2)]/c2

R1 - R2 = h

2lhΩ/c2

By having substracted two different Sagnac phase shifts, valid for the two different segments, we obtain the CORIOLIS EFFECT formula.


However, for the SAGNAC EFFECT, we have a single CONTINUOUS CLOCKWISE PATH, and a single CONTINUOUS COUNTERCLOCKWISE PATH, as the definition of the Sagnac effect entails.


Title: Re: On Sandokhan definitions of the Sagnac and Coriolis Effects
Post by: sandokhan on August 27, 2019, 01:14:39 AM
I am now going to derive the true/correct SAGNAC EFFECT formula for the interferometer used by G. Sagnac in 1913:

(https://image.ibb.co/kisGKd/mgrot5.jpg)

Topologically, it is a square interferometer (in order to avoid dealing with the vx and vy components of v), the two segments M4l and lM1 can be joined into a single segment, M4M1.

Let us remember that Sagnac used ONLY THE AREA to derive the final phase-shift formula: 16πAΩ/λc.


(https://i.ibb.co/bXJDkV1/sqrlg.jpg)

The Sagnac effect formula for a square interferometer which rotates around its own geometrical center.

Let L = r√2 (r = distance from point O to one of the corners)

Time travel along side AB:

dtab = L/(c - v/√2)

(distance from point O to one of the sides is r/√2, and since v = r x ω, velocity for the light beam traveling along a side is v/√2)

dtcounterclockwise = 8r/(√2c + v)

dtclockwise = 8r/(√2c - v)

Δt = 8rv/c2



Now, the much more difficult case for the same square interferometer located away from the center of rotation.

The laboratory at Sorbonne, in France, where Sagnac performed his experiments, ALSO was rotating, according to heliocentrism/RE theory, along with the Earth.

Let us now rotate the square interferometer by 135° in the clockwise direction: point A will be located in the uppermost position (the source of light will be placed at point A as well).

Distance from the center of rotation to point C is k2, while the distance from the center of rotation to point A is k1.

v1 = k1 x ω

v2 = k2 x ω

Proceeding exactly as in the case of the interferometer in the shape of a rectangle, we have two loops, one counterclockwise, one clockwise.

A > B > C > D > A is the clockwise path

A > D > C > B > A is the counterclockwise path

Sagnac phase components for the counterclockwise path (only the vx components of the velocity vector are subject to a different time phase difference in rotation, not the vy components):

L/(c - v1)

-L/(c + v2)

-L/(c + v2)

L/(c - v1)

Sagnac phase components for the clockwise path:

-L/(c + v1)

L/(c - v2)

L/(c - v2)

-L/(c + v1)

For the single continuous counterclockwise path we add the components:

L/(c - v1) - L/(c + v2) - L/(c + v2) + L/(c - v1) = 2L/(c - v1) - 2L/(c + v2)

For the single continuous clockwise path we add the components:

-L/(c + v1) + L/(c - v2) + L/(c - v2) - L/(c + v1) = -2L/(c + v1) + 2L/(c - v2)

The net time phase difference will be (let us remember that the counterclockwise phase difference has a negative sign attached to it, that is why the substraction of the phase differences becomes an addition):

2L/(c - v1) - 2L/(c + v2) -(-)[-2L/(c + v1) + 2L/(c - v2)] = 2L(2v1/c2) + 2L(2v2/c2) = 4L(v1 + v2)/c2

This is the correct global/generalized SAGNAC EFFECT formula for a square shaped  interferometer:

4L(v1 + v2)/c2

For the same interferometer, the CORIOLIS EFFECT formula is:

4Aω/c2


The phase difference for the SAGNAC EFFECT is:

Δφ = Δt x c/λ = [4L(v1 + v2)]/c2 x c/λ = [4L(v1 + v2)]/cλ


Sagnac did not derive a formula using TWO LOOPS, as required in the correct definition of the Sagnac effect: he simply used the AREA of the interferometer to obtain the CORIOLIS EFFECT formula, an equation derived nine years earlier by Michelson.

Title: Re: On Sandokhan definitions of the Sagnac and Coriolis Effects
Post by: sandokhan on August 27, 2019, 02:09:16 AM
Let us now compare the two formulas: the CORIOLIS EFFECT formula derived by G. Sagnac in 1913 and the SAGNAC EFFECT formula obtained using two loops.


CORIOLIS EFFECT formula (G. Sagnac, 1913)

Time difference

8AΩ1/c2


SAGNAC EFFECT formula

4L(v1 + v2)/c2

Latitude of Sorbonne: 48.85°

Thus, using the latitude of the laboratory in France, the formula becomes:

4Lv(cos2Φ1 + cos2Φ2)/c2

v = R x Ω2, where R = 4,197 km


RATIO

{4Lv(cos2Φ1 + cos2Φ2)/c2}/8AΩ1/c2 = RΩ2((cos2Φ1 + cos2Φ2)/2LΩ1

Φ1 = Φ2 = 48.85°

2((cos2Φ1 + cos2Φ2) = [3634.66 km x 7.29 x 10-5] = 0.265 km

2LΩ1 = 2 x 0.000294 km x 25 = 0.0147 km

0.265 km/0.0147 km = 18


Let us also compare the CORIOLIS EFFECT formula derived by Michelson in 1925 with the true/correct SAGNAC EFFECT formula:

The turning of the MGX area at the hypothetical rotational speed of the Earth takes place a distance of some 4,250 km from the center of the Earth (latitude 41°46').

FULL CORIOLIS EFFECT FOR THE MGX:

4AΩsinΦ/c2

FULL SAGNAC EFFECT FOR THE MGX:

4Lv(cos2Φ1 + cos2Φ2)/c2


Sagnac effect/Coriolis effect ratio:

R((cos2Φ1 + cos2Φ2)/hsinΦ

R = 4,250 km

h = 0.33924 km

The rotational Sagnac effect is much greater than the Coriolis effect for the MGX.

Φ1 = Φ = 41°46' = 41.76667°

Φ2 = 41°45' = 41.75°

R((cos2Φ1 + cos2Φ2) = 4729.885

hsinΦ = 0.225967

4729.885/0.225967 = 20,931.72

THE ROTATIONAL SAGNAC EFFECT IS 21,000 TIMES GREATER THAN THE CORIOLIS EFFECT.


G. Sagnac recorded ONLY the CORIOLIS EFFECT (proportional to the AREA) and not the ROTATIONAL SAGNAC EFFECT (proportional to the velocity/radius of rotation).

Coriolis Force and Sagnac Effect

Because of acting of gravity-like Coriolis force the trajectories of co- and anti-rotating photons have different radii in the rotating reference frame, while in the case of the equal radius the effective gravitational potentials for the photons have to be different.

Abstract
We consider the optical Sagnac effect, when the fictitious gravitational field simulates the reflections from the mirrors. It is shown that no contradiction exists between the conclusions of the laboratory and rotated observers. Because of acting of gravity-like Coriolis force the trajectories of
co- and anti-rotating photons have different radii in the rotating reference frame, while in the case of the equal radius the effective gravitational potentials for the photons have to be different.

Nowhere does he say he is deriving the Coriolis effect. He is simply using it to derive the Sagnac effect.

Quote from: sandokhan
That is why Sagnac had to use the formula which features the area and the angular velocity: he only measured the CORIOLIS EFFECT.

So, no! Sagnac had to use the formula which features the area and the angular velocity and he did measure the Sagnac effect.

Again, I repeat! The Coriolis effect is completely different LOOK:  the Coriolis Acceleration (https://wikimedia.org/api/rest_v1/media/math/render/svg/db5d8685439b1ae8431d4e55444028acf1c79c5a)

Here is the precise proof, peer-reviewed in an IOP article.

THIS IS AN IOP ARTICLE, one of the most comprehensive papers on the Sagnac effect ever published.

No, it is NOT "precise proof". I have the utmost respect for Grigorii B. Malykin and Vera I. Pozdnyakova but I doubt you interpreted what they wrote correctly! Read this:
Quote from: Grigorii B. Malykin and Vera I. Pozdnyakova
Siberstein [798, 799] suggested an explanation of the Sagnac effect based on the direct consideration of effect of the Sagnac forces on the counterpropagating waves. . . . . The areas of the triangles are different."
Now, while "the areas of the triangles are different" Dr Siberstein had previously shown "Thus, even for a ≈ 10 or 20 km the difference would certainly be too small to be measured directly.
So Dr Silberstein certainly does not "derive the Coriolis effect" and on the contrary, he shows that its effect is "certainly be too small to be measured directly."

Quote from: sandokhan

The formula derived by Dr. Silberstein, peer reviewed in the IOP article, and described by the author as the "effect of the Coriolis forces" is this:

dt = 4ωA/c^2
Where is it "described by the author as the 'effect of the Coriolis forces' "? Silberstein showed that the Coriolis forces had negligible effect!

Read again what Grigorii B. Malykin and Vera I. Pozdnyakova wrote!

Dr. Ludwik Silberstein did not ever "prove that the real cause of the phenomenon measured by Georges Sagnac was the CORIOLIS FORCE EFFECT."
He showed that the light paths deviated from straight lines due to the Coriolis effect but by a negligible amount and so that was completely left out of his final result!

So Dr Silberstein certainly does not "derive the Coriolis effect" and on the contrary, he shows that its effect is "certainly be too small to be measured directly."

Point A is located at the detector
Point B is in the bottom right corner

Here is the most important part of the derivation of the full/global Sagnac effect for an interferometer located away from the center of rotation.
A > B > C > D > A is a continuous counterclockwise path, a negative sign -
A > D > C > B > A is a continuous clockwise path, a positive sign +

The Sagnac phase difference for the clockwise path has a positive sign.

The Sagnac phase difference for the counterclockwise has a negative sign.

Sagnac phase components for the A > D > C > B > A path (clockwise path):
l1/(c - v1)
-l2/(c + v2)
Look your so-called "Sagnac phase components" are NOT "phase components" but are "time delay components".
Just look at the dimensions - they are all (length)/(velocity) which is the travel time along each segment.
And travel times cannot possibly be negative, so please correct your signs! You need to remove the negative signs between the terms

I do not have the time to go through all your working to correct it.

Quote from: sandokhan
Sagnac phase components for the A > B > C > D > A path (counterclockwise path):
l2/(c - v2)
-l1/(c + v1)

For the single continuous clockwise path we add the components:
l1/(c - v1) - l2/(c + v2)

For the single continuous counterclockwise path we add the components:
l2/(c - v2) - l1/(c + v1)

The net phase difference will be (let us remember that the counterclockwise phase difference has a negative sign attached to it, that is why the substraction of the phase differences becomes an addition):

{l1/(c - v1) - l2/(c + v2)} - (-){l2/(c - v2) - l1/(c + v1)} = {l1/(c - v1) - l2/(c + v2)} + {l2/(c - v2) - l1/(c + v1)}

Rearranging terms:

l1/(c - v1) - l1/(c + v1) + {l2/(c - v2) - l2/(c + v2)} =
2(v1l1 + v2l2)/c2

Exactly the formula obtained by Professor Yeh:
But it should NOT be "Exactly the formula obtained by Professor Yeh" because his formula was for a Phase Conjugate Gyro!

Quote from: sandokhan

φ = -2(φ2 - φ1) = 4π(R1L1 + R2L2)Ω/λc = 4π(V1L1 + V2L2)/λc

Since Δφ = 2πc/λ x Δt, Δt = 2(R1L1 + R2L2)Ω/c2 = 2(V1L1 + V2L2)/c2

CORRECT SAGNAC FORMULA:
No, this is NOT the "CORRECT SAGNAC FORMULA"!

http://www.dtic.mil/dtic/tr/fulltext/u2/a170203.pdf (appendix 5.1)

This is how the correct Sagnac formula is derived: we have single continuous clockwise path, and a single continuous counterclockwise path.

If we desire the Coriolis effect, we simply substract as follows:

dt = l1/(c - v1) - l1/(c + v1) - (l2/(c - v2) - l2/(c + v2))

Of course, by proceeding as in the usual manner for a Sagnac phase shift formula for an interferometer whose center of rotation coincides with its geometrical center, we obtain:

2v1l1/(c2 - v21) - 2v2l2/(c2 - v22)

l = l1 = l2

2l[(v1 - v2)]/c2

2lΩ[(R1 - R2)]/c2

R1 - R2 = h

2lhΩ/c2
And that is the Sagnac effect NOT Coriolis! As I noted above, you got half the signs incorrect in your so-called Sagnac time-delay formula!

Quote from: sandokhan
By having substracted two different Sagnac phase shifts, valid for the two different segments, we obtain the CORIOLIS EFFECT formula.

The CORIOLIS EFFECT applied to light beams certainly involves an AREA.

Here is a complete demonstration.

Spinning Earth and its Coriolis effect on the circuital light beams

A very direct, undergraduate level derivation.

The final formula is this:

dt = 4ωA/c^2

Therefore, contrary to the desperate attempts to suggest otherwise, the CORIOLIS EFFECT formula for light beams does involves the area of the interferometer.

Coriolis Force and Sagnac Effect

Because of acting of gravity-like Coriolis force the trajectories of co- and anti-rotating photons have different radii in the rotating reference frame, while in the case of the equal radius the effective gravitational potentials for the photons have to be different.

The author describes the fact that if the interferometer has sides which are not equal, or which have an irregular shape, as in the case referenced to G. Sagnac's 1913 experiment, then the CORIOLIS FORCE upon the light beams will be recorded.

Very simple.

Here is the demonstration using differential geometry.

(http://image.ibb.co/cUTCax/cor1.jpg)
(http://image.ibb.co/jGVx8H/cor2.jpg)

Therefore, contrary to the desperate attempts to suggest otherwise, the CORIOLIS FORCE effect upon the light beams will be recorded in Sagnac's irregularly shaped interferometer.


And the desperate tactics continue unabated on the part of the RE.

Here read this from p 298:

On page 298 there are two DIFFERENT derivations, a fact quite obvious for anyone but yourself.

You are quoting from the previous derivation, the equation of the light path in relation to Fermat's principle.

he shows that the deviations from straight are so slight that it cannot affect the result.

Yes, for the light path in terms of Fermat's principle.

Then, he starts to derive the CORIOLIS EFFECT on the same page, a totally different derivation.

The quote refers to FERMAT'S PRINCIPLE, not to the next derivation which takes place on the same page:

(https://www.dropbox.com/s/60n3lab4h5nqkst/THE%20PROPAGATION%20OF%20LIGHT%20IN%20ROTATING%20SYSTEMS%2C%20Dr%20L%20Silberstein%20-%20p298.png?dl=1)

You must be pretty desperate to use these kinds of tactics in a debate.


http://www.conspiracyoflight.com/Michelson-Gale/Silberstein.pdf


The derivation for the light path in terms of FERMAT'S PRINCIPLE starts on page 293 and ends on page 298.

Now, while "the areas of the triangles are different" Dr Siberstein had previously shown "Thus, even for a ≈ 10 or 20 km the difference would certainly be too small to be measured directly."

For FERMAT'S PRINCIPLE, yes, NOT for the next derivation.

So, your entire argument amounts to nothing at all, with the exception of your devious and miserable tactics you are using to satisfy your cognitive dissonance.

The derivation for the CORIOLIS EFFECT starts quite obviously with these words, right on the same page 298:

The experimental possibilities with regard to the optical effect of the rotation of the Earth lie in another direction...

Yet, you quoted from the PREVIOUS derivation, based on FERMAT'S PRINCIPLE, which has nothing to do with the NEXT derivation, right on the same page, which is the CORIOLIS EFFECT.

This means that you are UNABLE to read a scientific paper.


The analysis in terms of FERMAT'S PRINCIPLE starts on page 293 and ends on page 298: the two formulas are of different orders!


Here is the final formula:

4akw/c x (...)

THIS FORMULA IS OF THE ORDER OF 1/C: O(1/c).

By constrast, the CORIOLIS EFFECT formula, whose derivation also begins on page 298, is of the order O(1/c2).


Two different formulas, yet the RE seem to be unable to differentiate between them.
Silberstein (798, 799) suggested an explanation for the Sagnac effect based on the direct consideration of the effect of the Coriolis force on the counterpropagating waves.

Those two references, 798 and 799 are EXACTLY the ones I provided in my messages.
Make no mistake about it: Dr. Silberstein derives the Coriolis effect, which is directly related to the area of the interferometer.


Therefore, the fact that Dr. Silberstein did derive the CORIOLIS EFFECT formula, which features an area, remains undisputed.

THIS IS AN IOP ARTICLE, one of the most comprehensive papers on the Sagnac effect ever published.

Title: Re: On Sandokhan definitions of the Sagnac and Coriolis Effects
Post by: sandokhan on August 27, 2019, 06:44:21 AM
There are no "negative times", a concept most laughable.

I am going to explain the entire phenomenon using even more details, so that everyone here will understand, once and for all, the correct description of the SAGNAC EFFECT.

The RE standard for the Sagnac effect:

https://www.mathpages.com/rr/s2-07/2-07.htm

If two pulses of light are sent in opposite directions around a stationary circular loop of radius R, they will travel the same inertial distance at the same speed, so they will arrive at the end point simultaneously. This is illustrated in the left-hand figure below.

(https://www.mathpages.com/rr/s2-07/2-07_files/image001.gif)

If the interferometer is being rotated, both pulses begin with an initial separation of 2piR from the end point, so the difference between the travel times is:

(https://www.mathpages.com/rr/s2-07/2-07_files/image002.gif)

Can everyone understand the mechanism?

Opposite directions, therefore WE SUBSTRACT THE DIFFERENCE IN TIME TRAVEL.

Moreover, we are dealing with TWO LOOPS.

Can everyone understand that the differences in time travel have to be substracted?

This is the correct way to derive the Sagnac formula:

Sagnac phase component for the clockwise path:

2πR(1/(c - v))

Sagnac phase component for the counterclockwise path:

-2πR(1/(c + v))

The continuous clockwise loop has a positive sign +

The continuous counterclockwise loop has a negative sign -

Good.

That is, if we want to find out the difference in travel times (opposite directions) we must substract them.


For an interferometer which is now located AWAY FROM THE CENTER OF ROTATION, the situation is a bit more complicated, but the same principle applies.

(http://www.conspiracyoflight.com/Michelson-Gale_webapp/image002.png)

Point A is located at the detector
Point B is in the bottom right corner
Point C is in the upper right corner
Point D is in the upper left corner

l1 is the upper arm.
l2 is the lower arm.

Let us remember that now we are dealing with DIFFERENT VELOCITIES for each arm, and DIFFERENT LENGTHS of each arm, a situation a bit more complex than the previous case analyzed here.


We need to designate the TWO LOOPS, as required by the definition of the Sagnac effect.

HERE IS THE DEFINITION OF THE SAGNAC EFFECT:

Two pulses of light sent in opposite direction around a closed loop (either circular or a single uniform path), while the interferometer is being rotated.

Loop = a structure, series, or process, the end of which is connected to the beginning.

A single continuous pulse A > B > C > D > A, while the other one, A > D > C > B > A is in the opposite direction, and has the negative sign.


So, for the first loop, the clockwise path, the A > D > C > B > A path, we have to deal with beams which are traveling IN OPPOSITE DIRECTIONS, that is, in order to find out the total time travel we need to substract the time differences, just like we did the first time: in effect we are adding two transit times, one of which is traveling in a opposite direction to the first, hence the opposite signs.

We substracted the time differences the first time around for the interferometer whose center of rotation coincides with its geometric center.

Now, we have a loop consisting of two different paths, which travel in opposite directions.

Therefore, to get the TOTAL TIME DIFFERENCE FOR THE CLOCKWISE PATH, we substract the time differences: again, in effect we are adding the transit times, but since one of them has an opposite direction, it will have a different sign than the first transit time, just like in the first example of the Sagnac interferometer.

Very simple, and at the same time we are dealing with a LOOP, as required by the defintion of the Sagnac effect.

Sagnac phase components for the A > D > C > B > A path (clockwise path):

l1/(c - v1)

-l2/(c + v2)

Now, we do the same thing for the counterclockwise path, the A > B > C > D > A path:

l2/(c - v2)

-l1/(c + v1)


For the single continuous clockwise path we now have the total time difference:

l1/(c - v1) - l2/(c + v2)


For the single continuous counterclockwise path we have the total difference:

l2/(c - v2) - l1/(c + v1)


TWO LOOPS as required by the definition of the Sagnac effect.

If we change the sign of the second term/phase component to +, that is:

l1/(c - v1)

l2/(c + v2)

then, we no longer have a LOOP, and moreover we are using the wrong sign for the direction of the second transit time; each transit time has a different direction, hence we must use opposite signs to correctly designate them in our analysis.

Let us remember the very defintion of the Sagnac effect: two loops are required to properly derive the formula.


Now, to obtain the final answer, WE SUBSTRACT THE TOTAL TIME DIFFERENCES FOR EACH PATH, since we are dealing with a counterclockwise path and a clockwise path, if we want the time phase, we need to substract the total time differences for each LOOP. Each loop has a different direction, as such it must have a different sign assigned to it.

The net phase difference will be (let us remember that the counterclockwise phase difference has a negative sign attached to it, that is why the substraction of the phase differences becomes an addition):

{l1/(c - v1) - l2/(c + v2)} - (-){l2/(c - v2) - l1/(c + v1)} = {l1/(c - v1) - l2/(c + v2)} + {l2/(c - v2) - l1/(c + v1)}

Rearranging terms:

l1/(c - v1) - l1/(c + v1) + {l2/(c - v2) - l2/(c + v2)} =

2(v1l1 + v2l2)/c2

Exactly the formula obtained by Professor Yeh:

φ = -2(φ2 - φ1) = 4π(R1L1 + R2L2)Ω/λc = 4π(V1L1 + V2L2)/λc

Since Δφ = 2πc/λ x Δt, Δt = 2(R1L1 + R2L2)Ω/c2 = 2(V1L1 + V2L2)/c2

CORRECT SAGNAC FORMULA:

2(V1L1 + V2L2)/c2


By contrast, what Michelson did is to remove the SIGN from each loop, in effect nullifying the very definition of the Sagnac effect: he compared two different sides, not the two loops, thus he obtained the CORIOLIS EFFECT formula.

The CORIOLIS EFFECT and the SAGNAC EFFECT are two very different phenomena, one is a physical effect while the other one is an electromagnetic effect: two different phenomena require two different formulas.

Since Δφ = 2πc/λ x Δt, Δt = 2(R1L1 + R2L2)Ω/c2 = 2(V1L1 + V2L2)/c2

CORRECT SAGNAC FORMULA:

2(V1L1 + V2L2)/c2

The very same formula obtained for a Sagnac interferometer which features two different lengths and two different velocities.

There are no "negative times", a concept most laughable.
That is exactly what I said, had you bothered to read it. But your signs do give "negative times" for some of the components!

Sagnac phase components for the A > D > C > B > A path (clockwise path):
l1/(c - v1)
-l2/(c + v2)
Look your so-called "Sagnac phase components" are NOT "phase components" but are "time delay components".
Just look at the dimensions - they are all (length)/(velocity) which is the travel time along each segment.
And travel times cannot possibly be negative, so please correct your signs! You need to remove the negative signs between the terms

I do not have the time to go through all your working to correct it.

Look at this term that you call a "Sagnac phase component", "-l2/(c + v2)".
          "l2" is a length and presumably positive,
          "c" and "v2" are velocities and c must be positive and much greater than "v2".

So your "Sagnac time delay component", -l2/(c + v2), must be negative.

And you, yourself said, "There are no "negative times", a concept most laughable."  QED!

Now fixed up the signs in your "Sagnac time delay" and then I might look at the rest of your copy-pasta!

The Coriolis effect is a physical effect upon the light beams: it is proportional to the area of the interferometer. It is a comparison of two sides.
This is the formula derived by G. Sagnac: 4AΩ/c^2.

THIS IS THE CORIOLIS EFFECT FORMULA.

Sure, but your expression, "4AΩ/c^2 . . . . derived by G. Sagnac" and almost everybody else except YOU is NOT the Coriolis effect!

This shows the correct Coriolis effect, with a bit of explanation!

The CORIOLIS EFFECT applied to light beams certainly involves an AREA.

Here is a complete demonstration.

https://www.ias.ac.in/article/fulltext/pram/087/05/0071

Spinning Earth and its Coriolis effect on the circuital light beams

A very direct, undergraduate level derivation.

The final formula is this:

dt = 4ωA/c^2


The topological aspects of the SAGNAC EFFECT have been researched only recently, this being the main reason why the CORIOLIS FORMULA, which features the AREA, has been substituted for the true SAGNAC EFFECT formula.

"Sagnac effect is a change in propagation time for light going in a closed path. The time delay Δt appears when a test equipment is rotated with an angular velocity Ώ. Sagnac effect is frequently used in rate gyros in navigational systems. Fiber optics is used with light-speed c inside the fiber in a circular light path. The difference in propagation time Δt for two opposite directions of light is described as

Δt = 4AΩ/c2

Where A is enclosed area. Δt is derived based on an integration of Ω over A.

According to Stokes' rule can an integration of angular velocity Ω over an area A be substituted by an integration of tangential component of translational velocity v along the closed line of length L limiting the given area. This interpretation gives

Δt = 4vL/c2

producing the same value as the earlier expression. This can also be demonstrated by geometrical relations. These two integrations have different physical implications. We must therefore decide which one is correct from a physical aspect. Mathematics can not tell us that. So the decision is whether the effect is caused by a rotating area or by a translating line. Since Sagnac effect is an effect in light that is enclosed inside an optical fiber we can conclude that Sagnac effect is distributed along a line and not over an area. No light and no rotation exists in the enclosed area. Sagnac detected therefore an effect of translation although he had to rotate the equipment to produce the effect inside the fiber.

We conclude that the later expression

Δt = 4vL/c2

is the correct interpretation."

http://www.gsjournal.net/Science-Journals/Research%20Papers-Astrophysics/Download/2159

"Sagnac effect is distributed along a line and not over a surface. The assumption that starts from an integration over a surface (2Aw; rotation) is mathematically correct (due to Stokes' rule) but equal to a line integral (vL; translation). We must decide if the reason is a translating line or a rotating surface from a physical point of view. The rotation theory is correct only mathematically. Since the effect is locked inside an optical fiber the translating line is the correct interpretation. Classification as a rotational effect is wrong."

Professor Ruyong Wang has proven the Sagnac effect applies to uniform/translational/linear motion:

https://arxiv.org/ftp/physics/papers/0609/0609202.pdf

http://web.stcloudstate.edu/ruwang/ION58PROCEEDINGS.pdf


Using very advanced concepts from topology, T.W. Barrett proves that the Sagnac effect can only be described by the original set of the equations published by J.C. Maxwell.

Moreover, in the Sagnac effect there are two vector potential components with respect to clockwise and counterclockwise beams. The measured quantity, as will be explained more fully below, is then the phase factor or the integral of the potential difference between those beams and related to the angular velocity difference between the two beams. Therefore, as the vector potential measures the momentum gain and the scalar potential measures the kinetic energy gain, the photon will acquire “mass.”

The different velocities of clockwise- and counter-clockwise-rotating light beams in the Sagnac interferometer are due to the motion of the ether.


The observed interference effect is clearly the optical whirling effect due to the movement of the system in relation to the ether and directly manifests the existence of the ether.

This ether is a dynamic, and not an inert, ether.


However, the use of the phase-conjugate mirror has permitted physicists to obtain the true SAGNAC EFFECT formula, which is proportional to the VELOCITY of the light beams.

Title: Re: On Sandokhan definitions of the Sagnac and Coriolis Effects
Post by: sandokhan on August 27, 2019, 10:18:50 PM
Each time transit has a DEFINITE DIRECTION.

Opposite directions have opposite signs.

Let us go back to the original derivation of the Sagnac effect.

(https://www.mathpages.com/rr/s2-07/2-07_files/image002.gif)

To get the time transits IN OPPOSITE DIRECTIONS, you must assign a NEGATIVE SIGN to one of them.


If the interferometer is being rotated, both pulses begin with an initial separation of 2piR from the end point, so the difference between the travel times is:

(https://www.mathpages.com/rr/s2-07/2-07_files/image002.gif)

Opposite directions, therefore WE SUBSTRACT THE DIFFERENCE IN TIME TRAVEL.

Moreover, we are dealing with TWO LOOPS.

This is the correct way to derive the Sagnac formula:

Sagnac phase component for the clockwise path:

2πR(1/(c - v))

Sagnac phase component for the counterclockwise path:

-2πR(1/(c + v))

The continuous clockwise loop has a positive sign +

The continuous counterclockwise loop has a negative sign -

That is, if we want to find out the difference in travel times (opposite directions) we must substract them.


For an interferometer which is now located AWAY FROM THE CENTER OF ROTATION, the situation is a bit more complicated, but the same principle applies.

(http://www.conspiracyoflight.com/Michelson-Gale_webapp/image002.png)

Point A is located at the detector
Point B is in the bottom right corner
Point C is in the upper right corner
Point D is in the upper left corner

l1 is the upper arm.
l2 is the lower arm.

Let us remember that now we are dealing with DIFFERENT VELOCITIES for each arm, and DIFFERENT LENGTHS of each arm, a situation a bit more complex than the previous case analyzed here.


We need to designate the TWO LOOPS, as required by the definition of the Sagnac effect.

HERE IS THE DEFINITION OF THE SAGNAC EFFECT:

Two pulses of light sent in opposite direction around a closed loop (either circular or a single uniform path), while the interferometer is being rotated.

Loop = a structure, series, or process, the end of which is connected to the beginning.

A single continuous pulse A > B > C > D > A, while the other one, A > D > C > B > A is in the opposite direction, and has the negative sign.


So, for the first loop, the clockwise path, the A > D > C > B > A path, we have to deal with beams which are traveling IN OPPOSITE DIRECTIONS, that is, in order to find out the total time travel we need to substract the time differences, just like we did the first time: in effect we are adding two transit times, one of which is traveling in a opposite direction to the first, hence the opposite signs.

We substracted the time differences the first time around for the interferometer whose center of rotation coincides with its geometric center.

Now, we have a loop consisting of two different paths, which travel in opposite directions.

Therefore, to get the TOTAL TIME DIFFERENCE FOR THE CLOCKWISE PATH, we substract the time differences: again, in effect we are adding the transit times, but since one of them has an opposite direction, it will have a different sign than the first transit time, just like in the first example of the Sagnac interferometer.

Very simple, and at the same time we are dealing with a LOOP, as required by the defintion of the Sagnac effect.

Sagnac phase components for the A > D > C > B > A path (clockwise path):

l1/(c - v1)

-l2/(c + v2)

Now, we do the same thing for the counterclockwise path, the A > B > C > D > A path:

l2/(c - v2)

-l1/(c + v1)


For the single continuous clockwise path we now have the total time difference:

l1/(c - v1) - l2/(c + v2)


For the single continuous counterclockwise path we have the total difference:

l2/(c - v2) - l1/(c + v1)


TWO LOOPS as required by the definition of the Sagnac effect.

If we change the sign of the second term/phase component to +, that is:

l1/(c - v1)

l2/(c + v2)

then, we no longer have a LOOP, and moreover we are using the wrong sign for the direction of the second transit time; each transit time has a different direction, hence we must use opposite signs to correctly designate them in our analysis.

Let us remember the very defintion of the Sagnac effect: two loops are required to properly derive the formula.


Now, to obtain the final answer, WE SUBSTRACT THE TOTAL TIME DIFFERENCES FOR EACH PATH, since we are dealing with a counterclockwise path and a clockwise path, if we want the time phase, we need to substract the total time differences for each LOOP. Each loop has a different direction, as such it must have a different sign assigned to it.

The net phase difference will be (let us remember that the counterclockwise phase difference has a negative sign attached to it, that is why the substraction of the phase differences becomes an addition):

{l1/(c - v1) - l2/(c + v2)} - (-){l2/(c - v2) - l1/(c + v1)} = {l1/(c - v1) - l2/(c + v2)} + {l2/(c - v2) - l1/(c + v1)}

Rearranging terms:

l1/(c - v1) - l1/(c + v1) + {l2/(c - v2) - l2/(c + v2)} =

2(v1l1 + v2l2)/c2

Exactly the formula obtained by Professor Yeh:

φ = -2(φ2 - φ1) = 4π(R1L1 + R2L2)Ω/λc = 4π(V1L1 + V2L2)/λc

Since Δφ = 2πc/λ x Δt, Δt = 2(R1L1 + R2L2)Ω/c2 = 2(V1L1 + V2L2)/c2

CORRECT SAGNAC FORMULA:

2(V1L1 + V2L2)/c2


By contrast, what Michelson did is to remove the SIGN from each loop, in effect nullifying the very definition of the Sagnac effect: he compared two different sides, not the two loops, thus he obtained the CORIOLIS EFFECT formula.

The CORIOLIS EFFECT and the SAGNAC EFFECT are two very different phenomena, one is a physical effect while the other one is an electromagnetic effect: two different phenomena require two different formulas.

Each time transit has a DEFINITE DIRECTION.

Opposite directions have opposite signs.
But you end up with negative times! Which you then subtract again and
       so if V1 has the magnitude as V2 and if L1 has the magnitude as L2
You total transit time comes out as zero, which cannot be correct.

This is where we really disagree! There is no "TOTAL TIME DIFFERENCE FOR THE CLOCKWISE PATH". 
The times must all be added to get the total time around a path. No transit time can be negative - can't you see that is obvious?

Sagnac phase components for the A > D > C > B > A path (clockwise path):

-l2/(c + v2)

That is the crux of the problem.
Can't you see that if l1 = l2 AND v1 = v2 you would end up with zero transit time around that loop - impossible?

It could easily happen that l2/(c + v2) > l1/(c - v1) and that would end up with negative transit time "for the A > D > C > B > A path".

And we both agree that a negative transit time around any loop is quite impossible.

So there is no point in carrying on till this sticking point is resolved!

And also there is no point in repeating the same old claims that you keep posting!

Only someone who has nothing left to say, and is pretty desperate, can make a statement such as this:

Can't you see that if l1 = l2 AND v1 = v2 you would end up with zero transit time around that loop - impossible?

Which you then subtract again and  so if V1 has the magnitude as V2 and if L1 has the magnitude as L2
You total transit time comes out as zero, which cannot be correct.


For a Sagnac interferometer which is located AWAY FROM THE CENTER OF ROTATION, v1 and v2 can NEVER be the same, since l1 and l2 are located on different latitudes.

This much was assumed from the very start by Michelson, here is his derivation:

(http://image.ibb.co/fjSJy7/ahasag2.jpg)
(http://image.ibb.co/fPWNAn/ahasag4.jpg)

Therefore, to make such a mindless statement, to actually assume that v1 = v2, where, by definition, they can NEVER be the same, is beyond belief.


There is A DEFINITE direction of spin of rotation of the Earth, according to heliocentrism. That is why this fact is readily incorporated into the formula itself (by Michelson, by the ring laser gyroscopes physicists, by myself).


There is a single "beam" is travelling around the "A > D > C > B > A path" and the transit times in every segment must be added.

Exactly.

Both the counterclockwise and clockwise loops consist of TWO DIFFERENT PATHS/SIDES, l1 and l2.


Let us go back to how the original SAGNAC formula was derived.

The RE standard for the Sagnac effect:

https://www.mathpages.com/rr/s2-07/2-07.htm

If two pulses of light are sent in opposite directions around a stationary circular loop of radius R, they will travel the same inertial distance at the same speed, so they will arrive at the end point simultaneously. This is illustrated in the left-hand figure below.

(https://www.mathpages.com/rr/s2-07/2-07_files/image001.gif)

If the interferometer is being rotated, both pulses begin with an initial separation of 2piR from the end point, so the difference between the travel times is:

(https://www.mathpages.com/rr/s2-07/2-07_files/image002.gif)

There are NO "negative times": we have OPPOSITE DIRECTIONS, so we simply SUBSTRACT the time travels.


Very simple to understand.


This is the correct way to derive the Sagnac formula:

Sagnac phase component for the clockwise path:

2πR(1/(c - v))

Sagnac phase component for the counterclockwise path:

-2πR(1/(c + v))

The continuous clockwise loop has a positive sign +

The continuous counterclockwise loop has a negative sign -

That is, if we want to find out the difference in travel times (opposite directions) we must substract them.


For an interferometer which is now located AWAY FROM THE CENTER OF ROTATION, the situation is a bit more complicated, but the same principle applies.

(http://www.conspiracyoflight.com/Michelson-Gale_webapp/image002.png)

Point A is located at the detector
Point B is in the bottom right corner
Point C is in the upper right corner
Point D is in the upper left corner

l1 is the upper arm.
l2 is the lower arm.

Let us remember that now we are dealing with DIFFERENT VELOCITIES for each arm, and DIFFERENT LENGTHS of each arm, a situation a bit more complex than the previous case analyzed here.


We need to designate the TWO LOOPS, as required by the definition of the Sagnac effect.

Sagnac phase components for the A > D > C > B > A path (clockwise path):

l1/(c - v1)

-l2/(c + v2)

Now, we do the same thing for the counterclockwise path, the A > B > C > D > A path:

l2/(c - v2)

-l1/(c + v1)


For the single continuous clockwise path we now have the total time difference:

l1/(c - v1) - l2/(c + v2)


For the single continuous counterclockwise path we have the total difference:

l2/(c - v2) - l1/(c + v1)


TWO LOOPS as required by the definition of the Sagnac effect.

If we change the sign of the second term/phase component to +, that is:

l1/(c - v1)

l2/(c + v2)

then, we no longer have a LOOP, and moreover we are using the wrong sign for the direction of the second transit time; each transit time has a different direction, hence we must use opposite signs to correctly designate them in our analysis.

Let us remember the very defintion of the Sagnac effect: two loops are required to properly derive the formula.


Now, to obtain the final answer, WE SUBSTRACT THE TOTAL TIME DIFFERENCES FOR EACH PATH, since we are dealing with a counterclockwise path and a clockwise path, if we want the time phase, we need to substract the total time differences for each LOOP. Each loop has a different direction, as such it must have a different sign assigned to it.

The net phase difference will be (let us remember that the counterclockwise phase difference has a negative sign attached to it, that is why the substraction of the phase differences becomes an addition):

{l1/(c - v1) - l2/(c + v2)} - (-){l2/(c - v2) - l1/(c + v1)} = {l1/(c - v1) - l2/(c + v2)} + {l2/(c - v2) - l1/(c + v1)}

Rearranging terms:

l1/(c - v1) - l1/(c + v1) + {l2/(c - v2) - l2/(c + v2)} =

2(v1l1 + v2l2)/c2

Exactly the formula obtained by Professor Yeh:

φ = -2(φ2 - φ1) = 4π(R1L1 + R2L2)Ω/λc = 4π(V1L1 + V2L2)/λc

Since Δφ = 2πc/λ x Δt, Δt = 2(R1L1 + R2L2)Ω/c2 = 2(V1L1 + V2L2)/c2

CORRECT SAGNAC FORMULA:

2(V1L1 + V2L2)/c2


By contrast, what Michelson did is to remove the SIGN from each loop, in effect nullifying the very definition of the Sagnac effect: he compared two different sides, not the two loops, thus he obtained the CORIOLIS EFFECT formula.

The CORIOLIS EFFECT and the SAGNAC EFFECT are two very different phenomena, one is a physical effect while the other one is an electromagnetic effect: two different phenomena require two different formulas.


Each time transit has a DEFINITE DIRECTION.

Opposite directions have opposite signs.

Let us go back to the original derivation of the Sagnac effect.

(https://www.mathpages.com/rr/s2-07/2-07_files/image002.gif)

To get the time transits IN OPPOSITE DIRECTIONS, you must assign a NEGATIVE SIGN to one of them.

Only someone who has nothing left to say, and is pretty desperate, can make a statement such as this:

Can't you see that if l1 = l2 AND v1 = v2 you would end up with zero transit time around that loop - impossible?

Which you then subtract again and  so if V1 has the magnitude as V2 and if L1 has the magnitude as L2
You total transit time comes out as zero, which cannot be correct.


For a Sagnac interferometer which is located AWAY FROM THE CENTER OF ROTATION, v1 and v2 can NEVER be the same, since l1 and l2 are located on different latitudes.
Yes, they can be the same! The two different latitudes could be equally spaced either side of the equator.
So a huge loop could  hypothetically have been at 1°N and 1°S and so V1 would have the same magnitude as V2 and L1 can easily be made the same magnitude as L2.

If your calculations are correct then they should show zero Sagnac delay in that situation but they do not.

And I've found that a good technique for checking a calculation like that is to test it with extreme situations where the results are obvious.

And, of course, your expression can only be accurate when the centre of rotation is far outside the loop
so is not a general expression as is Maraner and Zendri's: (https://www.dropbox.com/s/ov40a15kkr8uogv/General%20relativistic%20Sagnac%20formula%20revised%2C%20Maraner%2C%20Zendri%20-%20eqn%20%2817%29.png?dl=1)

But you claim this:
Quote from: sandokhan

CORRECT SAGNAC FORMULA:

2(V1L1 + V2L2)/c2
And for V1 = V2 ≠ 0 and L1 = L2 ≠ 0 your expression will give a non-zero answer but the Sagnac delay should be zero for that case.

Look at the result the "Conspiracy of Light" site (the source of your diagram,  I believe) gives for it

It's funny how everybody seems to agree that the "4AΩ/c^2 . . . . derived by G. Sagnac" is the Sagnac effect.

And you seems totally confused about the real Coriolis effect!

This is the formula derived by G. Sagnac: 4AΩ/c^2.

THIS IS THE CORIOLIS EFFECT FORMULA.
Sure, but your expression, "4AΩ/c^2 . . . . derived by G. Sagnac" is NOT the Coriolis effect as everybody else seems to know!

This shows the correct Coriolis effect, with a bit of explanation!

Your tricks don't work with me.

v1 and v2 cannot, EVER, be the same, since l1 and l2 are located on different latitudes: the situation where you'd have the interferometer located right on the equator is a special case of my formula which, again, provides the correct answer.

It can easily be seen to be incorrect by simply centring the loop over the equator when: V1 = V2 = V and L1 = L2 = L.

In that situation there should obviously be no Sagnac delay, but your expression gives a delay of: 4(V L)/c2 .

But there is a Sagnac delay, right on the equator!

Agreed, but that is around the whole equator of the rotating earth and is quite irrelevant to your loop.

The global SAGNAC EFFECT formula applies to the interferometer whose center of rotation is located away from its geometrical center.

It works perfectly.

If the center of rotation coincides with the geometrical center, then you use the local SAGNAC EFFECT formula:  if v1 = v2 and l1 = l2, then quite simply, my formula becomes dt = 4VL/c^2, which is the local Sagnac effect formula.

Agreed, but that is around the whole equator of the rotating earth and is quite irrelevant to your loop.

There is no agreement with your previous statement:

In that situation there should obviously be no Sagnac delay,

But THERE IS a Sagnac delay, right on the line of the equator:

https://www.researchgate.net/publication/260796097_Light_Transmission_and_the_Sagnac_Effect_on_the_Rotating_Earth

"Kelly [25]  also  noted that  measurements  using  the GPS  reveal that  a light signal takes  414 nanoseconds  longer  to  circumnavigate  the  Earth  eastward  at  the  equator  than  in the westward direction around the same path. This is as predicted by GPS equations (11) and (12)."

If you now have equal radii and equal velocities, the local Sagnac formula comes into play at once.

You stated that there is no delay at the equator, yet you were proven to be quite wrong: there is a delay right on the equator, which is picked up by the local Sagnac effect formula, a successful trial for my global formula.

Once again, you seem to be very confused, you have no idea of what you are talking about.

You are simply trolling the lower forums.

A perfect "trial" for the global Sagnac effect formula: if you have equal lengths/velocities, then you use the local Sagnac effect formula, and you do have a delay just like proven by the above reference.


Now, if the center of rotation coincides with the geometrical center of the interferometer,  the instance where the interferometer is placed right on the equator, OBVIOUSLY the derivation will be modified for that situation: we use the classic Sagnac formula for two equal sides and two equal velocities:

dt = 4vL/c2


Proof (using my formula):

Sagnac components for the first loop:

l/(c - v)

-l/(c + v)

Sagnac components for the second loop:

l/(c - v)

-l/(c + v)


For the first loop:

l/(c - v) - l/(c + v) = 2vl/c2

For the second loop:

l/(c - v) - l/(c + v) = 2vl/c2

The net phase difference will be (let us remember that the counterclockwise phase difference has a negative sign attached to it, that is why the substraction of the phase differences becomes an addition):

{2vl/c2} -(-){2vl/c2} = 4vl/c2

My formula:

2(v1l1 + v2l2)/c2

If we now let l1 = l2 and v1 = v2, we get 4vl/c2, in perfect agreement.


And I've found that a good technique for checking a calculation like that is to test it with extreme situations where the results are obvious.

My formula works perfectly: therefore you must accept it.


It is proportional to the velocity of the object and has no connection with any area!

The Coriolis FORCE applied to light beams becomes the CORIOLIS EFFECT which actually is directly proportional to the AREA:

That is nothing like your loop. That is a loop around the equator and so has the centre of rotation right in the centre of the loop.

A loop like yours or that in the Michelson-Gale-Pearson experiment that is flat on the earth's surface should have a sin(latitude) term in it.

Sandy, I see you are yet to figure out the time taken for light to propagate around a stationary loop yet.

You are still using the same garbage derivation, producing the same garbage result.
Garbage in, garbage out.

You are still confusing times with time differences, and conflating phase conjugate mirrors with normal mirrors.
Even then, you still aren't doing it properly.

There are 2 valid ways of approaching the simple loop, and neither uses this garbage:
Quote
l1/(c - v1)

-l2/(c + v2)

You have 2 options, you can focus on the arms (equivalent to focusing on the loops in the PCM setup), or you can focus on the light paths.

Note: for the following derivation, all velocities will be measured as fractions of c, so c=1.

When focusing on the arms, you calculate the time differences/sagnac shift.
So arm 1, with length 1 has the following shift:
l1/(c - v1)-l1/(c + v1)=2l1v1.
For arm 2, and the combination we have 2 options.
We can find the shift the same way, and then find the difference, or we can note that the light is going in the opposite direction and thus use the below and then add the 2 shifts:
l2/(c + v2)-l2/(c + v2)=-2l2v2/c^2

Thus the total shift is (2l1v1-2l2v2)/c^2
which under the approximation of a annular sector = 4Aw/c^2

i.e. the same formula that every sane person produces.

Treating it as 2 light beams around a loop we instead focus on the times first:
Notice, the time for the 2 arms are added because it is a time and we are seeing how long it takes to go around the loop, ignoring the 2 arms where there is no shift.
The time for the first beam to go around the loop is given by:
l1/(c - v1)+l2/(c + v2)
Then for the beam going in the opposite directions, we change the sign of the velocity terms:
l1/(c + v1)+l2/(c - v2)

Then to find the shift, we find the difference of these times:
l1/(c - v1)+l2/(c + v2) - [l1/(c + v1)+l2/(c - v2)]
=l1/(c - v1)-l1/(c + v1) + l2/(c + v2)-l2/(c + v2)
Just like before.

It is nothing like the formula you are providing.

Your derivation is nothing more than garbage which has no connection to reality.
When trying to find a time taken to traverse the loop you instead find the time difference for a single beam of light propagating along the 2 arms, which doesn't equate to anything in the experiment.
Title: Re: On Sandokhan definitions of the Sagnac and Coriolis Effects
Post by: sandokhan on September 12, 2019, 10:05:06 PM
Let's put your word to the test.

Now instead of adding and subtracting based upon direction, we will add the terms of the same colour, corresponding to the one beam rotating around the interferometer and then find the difference.
dt=l1/(c - v1)+l2/(c + v2)-l1/(c + v1)-l2/(c - v2)
=l1/(c - v1)-l1/(c + v1)+l2/(c + v2)-l2/(c - v2)
=l1(c + v1-c + v1)/(c2 - v12)+l2(c - v2-c - v2)/(c2 - v22)
=2*l1v1/(c2 - v12)-2*l2v2/(c2 - v22)

Now, what the frell is this?

The author of this unscientific piece of garbage cannot distinguish between two opposite directions.

We no longer have a Sagnac interferometer whose center of rotation coincides with its geometrical center: the interferometer is located away from the center of rotation, as such each and every direction MUST HAVE THE CORRECT SIGN.

This guy has the same sign for opposite directions:

l1/(c - v1)+l2/(c + v2)

and

-l1/(c + v1)-l2/(c - v2)

Catastrophically wrong!!!

Here is the correct analysis:

Sagnac phase components for the A > D > C > B > A path (clockwise path):

l1/(c - v1)

-l2/(c + v2)

Sagnac phase components for the A > B > C > D > A path (counterclockwise path):

l2/(c - v2)

-l1/(c + v1)


For the single continuous clockwise path we add the components:

l1/(c - v1) - l2/(c + v2)

For the single continuous counterclockwise path we add the components:

l2/(c - v2) - l1/(c + v1)


The proper signs, in accordance with the direction, are in place.

What jackblack did is to substract the phase differences for TWO SEPARATE OPEN SEGMENTS, and not for the TWO LOOPS (as required by the defintion of the Sagnac effect).

He assigned the wrong signs, moreover, he did not complete the counterclockwise and the clockwise addition of the components of the phase differences.

We have the following terms, both have the same direction, that means one of them corresponds to the red in the inner segment and one to orange on the outer segment. I will colour code them for clarity:
l1/(c - v1)
l2/(c - v2)

Then, we have the remaining terms, in the opposite direction, likewise meaning one is for orange one is for red, noting that red travelled along l1 in the previous one so now it must travel along l2 in this one:
l1/(c + v1)
l2/(c + v2)

Then, if they ARE in opposite direction, they must have the OPPOSITE SIGN.

Here is the correct analysis:

Sagnac phase components for the A > D > C > B > A path (clockwise path):

l1/(c - v1)

-l2/(c + v2)

Sagnac phase components for the A > B > C > D > A path (counterclockwise path):

l2/(c - v2)

-l1/(c + v1)


For the single continuous clockwise path we add the components:

l1/(c - v1) - l2/(c + v2)

For the single continuous counterclockwise path we add the components:

l2/(c - v2) - l1/(c + v1)


jackblack assigned the SAME SIGN, even though he just said a few lines earlier, that they are in fact in opposite direction.


Where are your loops???

You are still comparing two OPEN SEGMENTS: defying the very definition of the Sagnac effect.

Path 1 - A>B, D>C.
Path 2 - C>D, B>A


Completely wrong!

The paths are very clear:

A > B > C > D > A is a continuous counterclockwise path, a negative sign -
A > D > C > B > A is a continuous clockwise path, a positive sign +

Yes, ignoring the sign which I don't particular care about at this time

You CANNOT ignore the sign, since by your own admission you have light beams travelling in opposite directions.

You are literally saying it takes negative time to do something.

No negative times at all.

Just two loops, continuous paths, as required by the definition of the Sagnac effect.

(http://www.conspiracyoflight.com/Michelson-Gale_webapp/image002.png)

Point A is located at the detector
Point B is in the bottom right corner
Point C is in the upper right corner
Point D is in the upper left corner

Here is the most important part of the derivation of the full/global Sagnac effect for an interferometer located away from the center of rotation.

A > B > C > D > A is a continuous counterclockwise path, a negative sign -

A > D > C > B > A is a continuous clockwise path, a positive sign +

The Sagnac phase difference for the clockwise path has a positive sign.

The Sagnac phase difference for the counterclockwise has a negative sign.


Sagnac phase components for the A > D > C > B > A path (clockwise path):

l1/(c - v1)

-l2/(c + v2)

Sagnac phase components for the A > B > C > D > A path (counterclockwise path):

l2/(c - v2)

-l1/(c + v1)


For the single continuous clockwise path we add the components:

l1/(c - v1) - l2/(c + v2)

For the single continuous counterclockwise path we add the components:

l2/(c - v2) - l1/(c + v1)


The net phase difference will be (let us remember that the counterclockwise phase difference has a negative sign attached to it, that is why the substraction of the phase differences becomes an addition):

{l1/(c - v1) - l2/(c + v2)} - (-){l2/(c - v2) - l1/(c + v1)} = {l1/(c - v1) - l2/(c + v2)} + {l2/(c - v2) - l1/(c + v1)}

Rearranging terms:

l1/(c - v1) - l1/(c + v1) + {l2/(c - v2) - l2/(c + v2)} =

2(v1l1 + v2l2)/c2


BY CONTRAST, here is what you did:

Now instead of adding and subtracting based upon direction, we will add the terms of the same colour, corresponding to the one beam rotating around the interferometer and then find the difference.
dt=l1/(c - v1)+l2/(c + v2)-l1/(c + v1)-l2/(c - v2)
=l1/(c - v1)-l1/(c + v1)+l2/(c + v2)-l2/(c - v2)
=l1(c + v1-c + v1)/(c2 - v12)+l2(c - v2-c - v2)/(c2 - v22)
=2*l1v1/(c2 - v12)-2*l2v2/(c2 - v22)

We have the following terms, both have the same direction, that means one of them corresponds to the red in the inner segment and one to orange on the outer segment. I will colour code them for clarity:
l1/(c - v1)
l2/(c - v2)

Then, we have the remaining terms, in the opposite direction, likewise meaning one is for orange one is for red, noting that red travelled along l1 in the previous one so now it must travel along l2 in this one:
l1/(c + v1)
l2/(c + v2)

Then, if they ARE in opposite direction, they must have the OPPOSITE SIGN.

You used the SAME sign for opposite directions.

Moreover, you compared two open segments, and not the two loops of the Sagnac interferometer.

l1/(c - v1)
l2/(c + v2)

Again, there are 4 legs, not 2. This means you should actually have 4 components.
If you assume arm 2 and 4 to be insignificant (which is technically wrong for a rectangle, as they need to be radial to have no effect, but then again you don't even have a constant v for a rectangle either), then you end up with arm 1, where the light is propagating with the motion of the apparatus, a time of (again, just accepting the formula you provided rather than double checking it):
l1/(c - v1)
which is larger than if it is at rest.

Then for the time in arm 3 you get:
l3/(c + v3)
which is smaller than if the arm is at rest.
You need to add these 2 POSITIVE times to get a reference time for the loop (as well as 2 lots for arm 2 and 4).


You seem to need medical attention jackblack.

Of course the times will be larger and smaller, since you are dealing with DIFFERENT VELOCITIES, c - v1 - v2 and c + v1 + v2.

Positive times? Everyone is laughing at you.

You used the wrong signs.

You compared two open segments, in full defiance of the definition of the Sagnac effect.

I added correctly the terms for the two loops.

Do you understand the definition of the Sagnac effect?

Let me remind you of it:

https://www.mathpages.com/rr/s2-07/2-07.htm

Two pulses of light are sent in opposite directions around a loop.

Loop = a structure, series, or process, the end of which is connected to the beginning.

What you, jackblack, have done, is to compare two open segments of the interferometer, and not the two loops as required by the definition of the Sagnac effect.

l1/(c - v1) + l2/(c + v2)

You have the wrong sign!!!

These beams are in opposite direction: one has a positive sign l1/(c - v1), the other has a negative sign -l2/(c + v2).

But again, we don't use your nonsense negative times.

There are NO negative signs.

Just TWO LOOPS: one counterclockwise, one clockwise.

Exactly as required by the defintion of the Sagnac effect.


EXPERIMENTAL PROOF THAT MY FORMULA IS ABSOLUTELY CORRECT:

(https://image.ibb.co/mtGWny/mgrot6.jpg)

The most ingenious experiment performed by Professor Yeh: light from a laser is split into two separate fibers, F1 and F2 which are coiled such that light travels clockwise in F1 and counterclockwise in F2.

https://www.researchgate.net/publication/26797550_Self-pumped_phase-conjugate_fiber-optic_gyro

Self-pumped phase-conjugate fiber-optic gyro, I. McMichael, P. Yeh, Optics Letters 11(10):686-8 · November 1986 

http://www.dtic.mil/dtic/tr/fulltext/u2/a170203.pdf (appendix 5.1)

The first phase-conjugate Sagnac experiment on a segment light path with a self-pumped configuration.

The Sagnac phase shift for the first fiber F1:

+2πR1L1Ω/λc

The Sagnac phase shift for the second fiber F2:

-2πR2L2Ω/λc

These are two separate Sagnac effects, each valid for the two fibers, F1 and F2.

The use of the phase conjugate mirror permits the revealing of the final formula, the total phase difference:

φ = -2(φ2 - φ1) = 4π(R1L1 + R2L2)Ω/λc

2(v1l1 + v2l2)/c2

Exactly the formula obtained by Professor Yeh:

φ = -2(φ2 - φ1) = 4π(R1L1 + R2L2)Ω/λc = 4π(V1L1 + V2L2)/λc

Since Δφ = 2πc/λ x Δt, Δt = 2(R1L1 + R2L2)Ω/c2 = 2(V1L1 + V2L2)/c2

CORRECT SAGNAC FORMULA:

2(V1L1 + V2L2)/c2



YOU ARE NOT USING THE DEFINITION OF THE SAGNAC EFFECT: TWO COUNTERPROPAGATING LOOPS.

You are comparing two sides, WITHOUT ANY LOOPS.

As such, your analysis is the CORIOLIS EFFECT formula, and not at all the SAGNAC EFFECT.

Let's put your word to the test.
We have done that repeatedly.
You have been unable to find a single error with my derivation, nor have you been able to support your nonsense.
You can even figure out how long it takes for light to propagate around a stationary ring.


The author of this unscientific piece of garbage cannot distinguish between two opposite directions.
No, I can, quite easily. That is why I have the c+v or c-v terms.

What you, the author of so much unscientific garbage it isn't funny, seems incapable of understanding, is how time doesn't give a damn what direction you are going in.

If you travel at a speed of 1 m/s, do you think it takes you 100 second to walk 100 m to the right, but -100 second to walk 100 m to the left?

Only a complete moron would think that.
Instead, it takes 100 second to walk 100 m to left or to the right at 100 m/s.
The direction does not effect the time.
So when you try to find out how long it takes for the light to propagate around the ring, you add the 2 times, you don't subtract.
Only a moron or a dishonest scumbag would subtract.

If there was a track with a length of l and you wanted to walk down to the end and back, travelling at a speed of c, would you find the time as:
t=l/c+l/c, or would you have it be t=l/c-l/c?
The former is one which makes sense.
Using 100 m and 1 m/s, that means it takes you 100 s to walk to the end and an additional 100 s to walk back.

But according to your garbage, which has no connection to reality at all, it takes no time at all, because the time spent walking in one direction magically cancels out the time spent walking in the other, as if walking to the right advances you forwards in time while walking to the left advances you backwards.

So when adding times, I will do the only sane thing, and ADD the times, not subtract just because the direction was different.
Again, only a complete moron or a dishonest scumbag would do otherwise.

So no, my derivation is correct.

We have the following terms, both have the same direction, that means one of them corresponds to the red in the inner segment and one to orange on the outer segment. I will colour code them for clarity:
l1/(c - v1)
l2/(c - v2)

Then, we have the remaining terms, in the opposite direction, likewise meaning one is for orange one is for red, noting that red travelled along l1 in the previous one so now it must travel along l2 in this one:
l1/(c + v1)
l2/(c + v2)
Then, if they ARE in opposite direction, they must have the OPPOSITE SIGN.
And what do I have?
One direction has c+v. The other has c-v. Notice how they have a different sign? One is -, one is +.
What has the same sign is the time, as they are both moving forwards in time, i.e. the temporal direction is the same.
If you want to tell us how they magically go backwards in time, feel free. Until you can justify such insanity, your "derivation" remains a pile of garbage completely unconnected to reality.

Sagnac phase components for the A > D > C > B > A path (clockwise path):
Again, this makes no sense.
You can discuss the phase components for the individual arms, and then combine them, or you can find the time for the light paths.
If you are taking times, you need to add the components, not subtract them, because they are times.

What you are doing is finding a difference in time for the same beam of light, which does not represent anything in reality.

This has all been pointed out before, and you were able to do was repeatedly spam the same garbage.
You were completely incapable of rationally defending your claims which is why I repeatedly asked you such a simple question:

How long does it take for the light to travel around a stationary loop? Can you tell us that?
Don't worry, the light is still travelling in a different direction, so you can still make up your BS about signs.

This is the CORIOLIS EFFECT formula:

Here is a very direct proof:

Spinning Earth and its Coriolis effect on the circuital light beams

http://www.ias.ac.in/article/fulltext/pram/087/05/0071

The CORIOLIS EFFECT formula features an AREA.


The SAGNAC EFFECT formula, on the other hand, does not deal with areas, only with velocities.

Here is a nice proof:

At this point, in a normal debate, the discussion is over.

I have just proven that the formula derived by having compared two sides of the interferometer is actually the CORIOLIS EFFECT formula.

I have posted the proof that the SAGNAC EFFECT does not require an area.


But both these shills are allowed to sabotage this forum, by posting the very same nonsense all over again, as if no counter-arguments had been presented to them.


One direction has c+v. The other has c-v. Notice how they have a different sign? One is -, one is +.

That is the VELOCITY, not the direction of the LIGHT BEAM.

My formula was flawlessly derived and I have arrived at the SAME formula featured in Professor Yeh's papers as well.

There is nothing else to discuss here.

I have to ask, "Do you even read your own references or take note of their titles? "

Look at the full title of the above reference: "Spinning Earth and its Coriolis effect on the circuital light beams: Verification of the special relativity theory SANKAR HAJRA".

Note first his object "Verification of the special relativity theory" which you do not accept.

Now look at his introduction:
(https://www.dropbox.com/s/fntznd75v70hcqn/Spinning%20Earth%20and%20its%20Coriolis%20effect%20on%20the%20circuital%20light%20beams%20-%20Verification%20of%20the%20special%20relativity%20theory%0Dby%20SANKAR%20HAJRA%20%28intro%29.png?dl=1)

If you claim he's deriving the Coriolis effect please explain:
Quote
In Bilger et al [1], Anderson et al [2], and in Michelson and Gale assisted by Pearson [3], Sagnac effect on the circuital laser/light beams on the spinning Earth has been studied.
The formula for Sagnac effect on the spinning Earth for circuital opposing beams of light first calculated by Silberstein [4] and used in the explanation of the Michelson–Gale experiment was:

Your own author, Sankar Ajra, calls it the Sagnac effect and he says the Michelson and Gale assisted by Pearson experiment the Sagnac effect.

All Sankar Ajra is doing is to derive the Sagnac effect using the Coriolis force and verifying of the special relativity theory.

This is the CORIOLIS EFFECT formula:
It is the Sagnac effect formula. You not liking that wont change it.

At this point, in a normal debate, the discussion is over.
Yes, you have been refuted.
Your argument has been shown to be completely wrong.
You have been unable to back up your derivation nor refute mine.
Instead all you can do is assert that you are correct and ignore any questions asked.

So yes, in a normal debate, the discussion would be over, you would accept that you were wrong and we would move on.

One direction has c+v. The other has c-v. Notice how they have a different sign? One is -, one is +.
That is the VELOCITY, not the direction of the LIGHT BEAM.
Yes, that is the velocity, the part where direction is important.
In one part the light moves with the motion of the beam and in the other the light moves against the motion.
That is the part where the sign matters.

Adding up the times doesn't change the sign.

Again, if you have someone who can run at a speed of c, who wants to run back and forth down a track of length l, is the time required:
t1=l/c+l/c, where we don't change the sign for opposite spatial directions, as both paths move forwards in time, or is it:
t2=l/c-l/c, where we change the sign for opposite spatial directions, meaning regardless of how long the path is it takes no time to run back and forth down it because you magically go backwards in time when you go backwards down the path?

It makes no sense to change the sign like that.
When you add the components for a single light path, you add the signs as you are adding up the time required to traverse the 2 beams.
You do not find the difference.

As such, your derivation has no connection to reality.

This is also why before I was repeatedly asking you how long it takes for light to traverse a stationary loop.
Using your nonsense you end up with a time of 0, regardless of the size of the loop.


Also note, you are being extremely inconsistent with this nonsense. When you have the centre of the interferometer aligned with the centre of rotation, you don't change sign with direction. Instead you just add up the times. So it is clear that you know you are spouting nonsense.

https://web.infn.it/GINGER/administrator/components/com_jresearch/files/publications/sagnac_AJP.pdf

The Sagnac effect and pure geometry

American Journal of Physics 83, 427 (2015)


They derive TWO FORMULAS for the same phenomenon.


The first one is:

Δt = 4Aω/c^2

A = area enclosed by the path of the light beams


Then, the authors derive A SECOND FORMULA for the Sagnac effect, which DOES NOT feature an area:

(https://image.ibb.co/cPs5vd/sagnac3.jpg)
(https://image.ibb.co/m86n8y/sagnac4.jpg)

This formula does not include the area at all, and is proportional to the VELOCITY of the light beams (and thus is proportional to the RADIUS of rotation).


Two different formulas, featuring two different physical descriptions.

This means that the formulas must be describing TWO DIFFERENT PHYSICAL PHENOMENA.


The first formula, which displays the AREA of the interferometer, is actually the CORIOLIS EFFECT formula:

https://www.ias.ac.in/article/fulltext/pram/087/05/0071

Spinning Earth and its Coriolis effect on the circuital light beams

The final formula is this:

dt = 4ωA/c^2


What is the corresponding formula for the Michelson-Gale interferometer which does not display an area and which is proportional to the velocity of the light beams?

Obviously, we now have to deal with two velocities for each side of the interferometer, v1 and v2, not to mention the two different lengths of each side.


Tartaglia and Ruggiero derived TWO formulas for the same phenomenon, but which obviously carry two very different physical and mathematical characteristics: one is proportional to the area of the interferometer, the other one is not.


Here, then, is the correct derivation of the SECOND FORMULA, which does not feature an area, for the Michelson-Gale interferometer:

(https://image.ibb.co/dbZ7Kd/gsac2.jpg)



I have just proven that the TRUE SAGNAC EFFECT FORMULA DOES NOT FEATURE AN AREA.


Only the CORIOLIS EFFECT formulas has an area incorporated into the equation.


You derived the following formula:

dt = 4ωA/c^2


In order to derive this formula, you compared two sides, not two loops, as required by the definition of the SAGNAC EFFECT.


When you have the centre of the interferometer aligned with the centre of rotation, you don't change sign with direction. Instead you just add up the times.

Completely wrong.

In fact, I posted the derivation from the mathpages to show you how wrong you are:

(https://www.mathpages.com/rr/s2-07/2-07_files/image002.gif)


THEY SUBSTRACT THE TIMES.


Can everyone understand the mechanism?

Opposite directions, therefore WE SUBSTRACT THE DIFFERENCE IN TIME TRAVEL.

Moreover, we are dealing with TWO LOOPS.

Can everyone understand that the differences in time travel have to be substracted?

This is the correct way to derive the Sagnac formula:

Sagnac phase component for the clockwise path:

2πR(1/(c - v))

Sagnac phase component for the counterclockwise path:

-2πR(1/(c + v))

The continuous clockwise loop has a positive sign +

The continuous counterclockwise loop has a negative sign -

Good.

That is, if we want to find out the difference in travel times (opposite directions) we must substract them.


So, on the most important part of your messages, YOU ARE COMPLETELY WRONG!


(http://www.conspiracyoflight.com/Michelson-Gale_webapp/image002.png)

Point A is located at the detector
Point B is in the bottom right corner
Point C is in the upper right corner
Point D is in the upper left corner

l1 is the upper arm.
l2 is the lower arm.

Let us remember that now we are dealing with DIFFERENT VELOCITIES for each arm, and DIFFERENT LENGTHS of each arm, a situation a bit more complex than the previous case analyzed here.


We need to designate the TWO LOOPS, as required by the definition of the Sagnac effect.

HERE IS THE DEFINITION OF THE SAGNAC EFFECT:

Two pulses of light sent in opposite direction around a closed loop (either circular or a single uniform path), while the interferometer is being rotated.

Loop = a structure, series, or process, the end of which is connected to the beginning.

A single continuous pulse A > B > C > D > A, while the other one, A > D > C > B > A is in the opposite direction, and has the negative sign.


So, for the first loop, the clockwise path, the A > D > C > B > A path, we have to deal with beams which are traveling IN OPPOSITE DIRECTIONS, that is, in order to find out the total time travel we need to substract the time differences, just like we did the first time: in effect we are adding two transit times, one of which is traveling in a opposite direction to the first, hence the opposite signs.

We substracted the time differences the first time around for the interferometer whose center of rotation coincides with its geometric center.

Now, we have a loop consisting of two different paths, which travel in opposite directions.

Therefore, to get the TOTAL TIME DIFFERENCE FOR THE CLOCKWISE PATH, we substract the time differences: again, in effect we are adding the transit times, but since one of them has an opposite direction, it will have a different sign than the first transit time, just like in the first example of the Sagnac interferometer.

Very simple, and at the same time we are dealing with a LOOP, as required by the defintion of the Sagnac effect.

Sagnac phase components for the A > D > C > B > A path (clockwise path):

l1/(c - v1)

-l2/(c + v2)

Now, we do the same thing for the counterclockwise path, the A > B > C > D > A path:

l2/(c - v2)

-l1/(c + v1)


For the single continuous clockwise path we now have the total time difference:

l1/(c - v1) - l2/(c + v2)


For the single continuous counterclockwise path we have the total difference:

l2/(c - v2) - l1/(c + v1)


TWO LOOPS as required by the definition of the Sagnac effect.

If we change the sign of the second term/phase component to +, that is:

l1/(c - v1)

l2/(c + v2)

then, we no longer have a LOOP, and moreover we are using the wrong sign for the direction of the second transit time; each transit time has a different direction, hence we must use opposite signs to correctly designate them in our analysis.

Let us remember the very defintion of the Sagnac effect: two loops are required to properly derive the formula.


Now, to obtain the final answer, WE SUBSTRACT THE TOTAL TIME DIFFERENCES FOR EACH PATH, since we are dealing with a counterclockwise path and a clockwise path, if we want the time phase, we need to substract the total time differences for each LOOP. Each loop has a different direction, as such it must have a different sign assigned to it.

The net phase difference will be (let us remember that the counterclockwise phase difference has a negative sign attached to it, that is why the substraction of the phase differences becomes an addition):

{l1/(c - v1) - l2/(c + v2)} - (-){l2/(c - v2) - l1/(c + v1)} = {l1/(c - v1) - l2/(c + v2)} + {l2/(c - v2) - l1/(c + v1)}

Rearranging terms:

l1/(c - v1) - l1/(c + v1) + {l2/(c - v2) - l2/(c + v2)} =

2(v1l1 + v2l2)/c2


You are out of options: no more trolling, spamming from you.

Professors Tartaglia and Ruggiero have derived TWO FORMULAS, one features an area, the other does not.

I was able, for the first time in history, to derive the corresponding SECOND formula for the Michelson-Gale experiment.


Remember: you MUST address the fact that Tartaglia and Ruggiero derived the SAGNAC EFFECT formula WITHOUT AN AREA.

NO area at all!




Title: Re: On Sandokhan definitions of the Sagnac and Coriolis Effects

The first shill has been confined to the AR.

The second shill can no longer use trolling, stalling, spamming to escape the final conclusion: my formula is correct.
But you are the one who is repeatedly trolling, stalling and spamming.

When you first brought up your claims regarding the Sagnac effect you fully accepted that the formula was 4*A*omega/c^2, and accepted that it applied to any interferometer, but claimed that the area used was the area of the "orbit", such that the orbital Sagnac was based on the area of Earth's orbit around the sun, while for Earth's rotation it would be the area or a circle centred on Earth's axis and passing through the interferometer.
But you had that argument completely refuted and I provided a derivation from first principles for an annular interferometer showing it was the area of the interferometer which mattered, not the orbit.
You were completely unable to refute that and spammed a bunch more of baseless assertions before running away.

You then came up with a few false derivations which were also refuted.
For example, you brought in fibre optic conveyors, which while having a similar origin, are fundamentally different.
The apparatus no longer moves as one, it moves relative to itself.
It is irrelevant to the discussion on the Sagnac effect for a simple ring interferometer.

It also doesn't show what you claim.
The shift is not proportional to some fictitious absolute velocity of the interferometer. It is proportional to the velocity of the source/detector relative to the conveyor.
So it doesn't prove what you are claiming at all.
Another important distinction is that it uses the entire length, not just the length of 2 arms.
So no, it doesn't apply.

You have been completely unable to justify your derivation at all. As such it is proof of nothing. It remains a pile of refuted garbage.

Meanwhile, you have been completely unable to refute my derivation at all (either of them).

This formula does not include the area at all, and is proportional to the VELOCITY of the light beams (and thus is proportional to the RADIUS of rotation).
Two different formulas, featuring two different physical descriptions.
This means that the formulas must be describing TWO DIFFERENT PHYSICAL PHENOMENA.
Not quite. It is the velocity, not of the light beams, but of the source/detector relative to the conveyor.
There is no radius here. There is no rotation, except where the conveyor turns a corner.

A fibre optic conveyor, while similar to a Sagnac interferometer, is not one. Its formula is not that for the Sagnac effect.

In order to derive this formula, you compared two sides, not two loops, as required by the definition of the SAGNAC EFFECT.
No, that would be what you have repeatedly done.
I have compared 2 loops (really just the one loop, with 2 beams of light going in different directions).
I added up the time taken for each loop to complete, and then I found the difference between those 2 times, to find the shift.
Instead, you looked at the time taken for a beam of light to traverse each arm and found the difference in those times, not corresponding to anything in reality.

When you have the centre of the interferometer aligned with the centre of rotation, you don't change sign with direction. Instead you just add up the times.
Completely wrong.
No, completely true.
You take the time taken to traverse each tiny section of the arm and add them all up to find the total time taken to traverse the loop.
But now you want to throw that out the window and find some difference in this time which makes no sense at all.

THEY SUBSTRACT THE TIMES.
For the 2 different counterpropogating beams, not for the same beam.
For a single beam they add up the time.

This matches what I did.
We have one beam which traverses the loop in one direction. The time taken to traverse the arms of interest are the following:
l1/(c - v1)
l2/(c + v2)
Notice the difference in sign of the velocity term as in one case the light is moving with the arm, while in the other it is moving against it.
This means for this beam of light, the total time (that we care about) is:
l1/(c - v1) + l2/(c + v2).

Likewise we do the same for the other BEAM OF LIGHT and end up with:
l2/(c - v2) + l1/(c + v1).

Note: these correspond to the time taken for the clockwise path and counterclockwise path for a simple ring interferometer:
2πR(1/(c - v))
2πR(1/(c + v))

Notice that they add up the single light path.
They don't do something like this:
"Well for half of the path it goes in one direction, so it has a Sagnac phase component of πR(1/(c - v)), but then for the other half it goes in the opposite direction so it has a phase component of -πR(1/(c - v)), giving us a total of 0."

Now, we find the difference in time between the light beams to find the time shift at the detector. This is where the difference comes in. It is the difference in time for the 2 beams of light:
dt=l1/(c - v1) + l2/(c + v2) - (l2/(c - v2) + l1/(c + v1))
=l1/(c - v1) - l1/(c + v1) + l2/(c + v2) - l2/(c - v2)
=l1(c + v1 - c + v1)/(c2 - v12) + l2(c - v2 - c + v2)/(c2 - v22)
=2 l1 v1/(c2 - v12) - 2 l2 v2/(c2 - v22)
Then when you note v is tiny compared to c, this simplifies to:
dt=2 l1 v1/c2 - 2 l2 v2/c2
2(l1 v1 - l2 v2)/c2

Just like I have proven countless times.
And when you note that this needs to be an annular interferometer for the other arms to not matter, this results in the same old formula:
dt=4Aw/c^2

Meanwhile you are subtracting the times for a single beam which makes no sense and corresponds to nothing in reality.

Opposite directions, therefore WE SUBSTRACT THE DIFFERENCE IN TIME TRAVEL.
No, 2 different beams which produce an interference pattern, so we find the difference in time taken for the beams. We don't find a difference in time taken for a single beam to traverse the different arms as that corresponds to nothing in reality.

So, for the first loop, the clockwise path, the A > D > C > B > A path, we have to deal with beams which are traveling IN OPPOSITE DIRECTIONS, that is, in order to find out the total time travel we need to substract the time differences
Again, THIS MAKES NO SENSE!
Again, if you have someone who can run at a speed of c, who wants to run back and forth down a track of length l, is the time required:
t1=l/c+l/c, where we don't change the sign for opposite spatial directions, as both paths move forwards in time, or is it:
t2=l/c-l/c, where we change the sign for opposite spatial directions, meaning regardless of how long the path is it takes no time to run back and forth down it because you magically go backwards in time when you go backwards down the path?

According to your nonsense, you find the difference and can end up with no time taken at all.
According to almost everyone, you add the times together to find the total time.
Do you understand what a total is? It is what you get when you add up the components. It is not a difference.

For any individual light path you add the time taken for it to traverse the individual components to find the total time taken.
The only time you would subtract is if the light beam magically travels backwards in time.

This is why your derivation amounts to nothing more than pure bovine excrement.
Because you are trying to find a total time by finding a difference in time taken.
Do you not realise that they are vastly different things?

I was able, for the first time in history, to derive the corresponding SECOND formula for the Michelson-Gale experiment.
And have you considered that that the reason for that is because you have made a massive mistake? A mistake which has been pointed out to you countless times, which you have repeatedly ignored?

And again, your formula can be shown to be pure nonsense by also considering what happens with a rectangular interferometer travelling in uniform linear motion (i.e. without any rotation at all).
According to simple symmetry the 2 light paths will be equivalent and thus there will be no shift as neither beam of light can get ahead of the other.
i.e. the light travelling clockwise along arm 1 will be the same as the light travelling counterclockwise along arm 3, and so on for all the other arms. This means the total shift must be 0.
My formula indicates the following:
dt=2(l v - l v)/c2 = 0.
Meanwhile your nonsense indicates the following:
2(l v + l v)/c2 = 2 l v / c2

This is a massive problem for you.
Your formula produces an incorrect result in one of the simplest cases.
This shows your formula is nonsense.

So no, you haven't made some historic break through. You have just made a massive mistake.

This is what you actually need to deal with. To summarise:
You need to refute my derivation which you have been unable to show any problem with.
You need to explain why you are finding the difference in time taken for a single beam of light, which corresponds to nothing in reality, and pretending it is the total time taken.
You need to explain why an interferometer which isn't rotating at all and instead is moving with uniform linear motion has a Sagnac shift, when symmetry demands it can't (and my formula says it can't, and the formula produced by so many people says it can't).

And these are all problems which have been pointed out to you before which you have chosen to ignore.

We are left now with jackblack's trolling.

Just take a look at this:

A fibre optic conveyor, while similar to a Sagnac interferometer, is not one. Its formula is not that for the Sagnac effect.

Here is the reference, published in one of the most respected journals:

I now ask the admin and the mods: how would you deal with something like this, where a user REFUSES to accept reality and scientific references which obviously negate his statement?


jackblack is REFUSING to accept the plain scientific facts referenced in a peer-reviewed paper.


Imagine this: the very title of the paper and of the particular section mentions the SAGNAC EFFECT, yet jackblack says, "no".


How is this a debate?


Is this not trolling, to DEFY and NEGATE the obvious evidence presented?


jackblack is refusing to accept reality, and this means he has certain psychological problems which are not any of our business to cure here.


He is trolling in plain view this forum, refusing to accept the clear evidence presented in front of him.



Plus the usual vindictivness.

It remains a pile of refuted garbage.

This is why your derivation amounts to nothing more than pure bovine excrement.


jackblack has derived the CORIOLIS EFFECT.

Here is the proof:

Spinning Earth and its Coriolis effect on the circuital light beams

The final formula is this:

dt = 4ωA/c^2



jackblack is refusing to accept defeat and to accept that his formula is clearly described as the CORIOLIS EFFECT.


Yet, he is allowed to troll this forum, again and again.


He is not here to debate at all, but only to NEGATE.


This is where any debate would stop: clearly I have proven that the formula derived by jackblack is actually the CORIOLIS EFFECT.

My reference clearly shows this to be true.

Yet, this user is refusing to accept reality.


The true SAGNAC EFFECT does not feature an area.

I have just proven, using a well-known reference, that the SAGNAC EFFECT formula does not and cannot include the area of the interferometer.


I have just proven, using another reference, that jackblack's formula is the CORIOLIS EFFECT equation.


But he won't accept these plain scientific facts.

jackblack dismisses the references as "pure garbage".

Each and every point of this message has been thoroughly addressed, again and again, for the past months, yet he won't listen and continues to spam this forum with his unaltered vindictivness.

How about you stop with the insults and instead try to deal with the issues raised?

I now ask the admin and the mods: how would you deal with something like this, where a user REFUSES to accept reality and scientific references which obviously negate his statement?
This is a site built upon the rejection of accepted science.
It rejected the accepted science of Earth being round and rotating and orbiting the sun.
Why should rejecting your interpretation of science be a problem?

Do you want to just accept what mainstream science says?
That means accepting Earth is a round, rotating planet which orbits the sun, and that the sagnac effect for a simple ring interferometer is given by 4Aw/c^2, regardless of where the centre of rotation is.

So do you really want that? Or do you want to try justifying claims without appealing to what mainstream science says?

But don't worry, it isn't only me that rejects that. Here is a quote from someone you hold in very high regards defining the Sagnac effect (colouring and bolding mine):
HERE IS THE DEFINITION OF THE SAGNAC EFFECT:
Two pulses of light sent in opposite direction around a closed loop (either circular or a single uniform path), while the interferometer is being rotated.
A similar (identical) quote can be found in the following posts:
https://www.theflatearthsociety.org/forum/index.php?topic=78424.msg2118464#msg2118464
https://www.theflatearthsociety.org/forum/index.php?topic=30499.msg2117351#msg2117351

https://www.theflatearthsociety.org/forum/index.php?topic=79931.msg2198088#msg2198088

You yourself have stated quite clearly that the definition of the Sagnac effect requires that the interferometer is rotating.
Notice how that does not include an fibre optic conveyor?
Notice how that goes directly against the paper you cite.
You are literally arguing with yourself.

Yes, the Sagnac effect can be generalised to a fibre optic conveyor or a similar system, but that is not what is being discussed here. We are not discussing a stationary light path with a source/detector moving along this path, with the length of the light path being the only length we care about and the velocity of the source/detector along the light path being the only velocity we care about (yes, notice how this has just one velocity and one length, and in this case that is actually critical to how it works. The derivation relies upon it). We are discussing a rotating light path, something significantly different.

How is this a debate?
You are correct, it isn't debate. It is trolling.
You repeatedly ignore what I say.
You repeatedly ignore the massive issues I raise with your derivation and your claims.
Instead you just spam the same nonsense and argue with yourself.

Notice how no where in your post do you deal with the simple points I raised?

Again, simple symmetry demands that for a rectangular interferometer moving at a constant speed with uniform linear motion, such that l1=l2 and v1=v2, there can be NO Sagnac shift. The 2 paths are indistinguishable and thus both beams take the same time to transit the loop and there is no shift.
My formula correctly predicts no shift.
Your formula falsely predicts a shift.
This is a massive problem for your formula and shows that it cannot be correct.


Again, when finding the Sagnac shift based upon a time difference, the important value to calculate is the difference in time taken for the 2 light paths.
If there is not a simple value for the time for a light path it can be constructed by adding the individual components, but it still adds the time taken.
This is what my derivation does, adding up the time taken for the beam of light to traverse the relevant arms of the interferometer, and the finding the difference in time taken for the 2 beams of light.
Your "derivation" meanwhile finds the difference in time taken for a single beam of light to traverse the 2 arms, corresponding to absolutely nothing in reality.

Now, care to address the issues raised?

Here is what you said earlier:

A fibre optic conveyor, while similar to a Sagnac interferometer, is not one. Its formula is not that for the Sagnac effect.


A sensible person would immediately write to the American Physics Journal, perhaps even to the authors of the paper, that you do not agree with the definition and proof they published.

Then see what kind of a response you'd get back.


You are telling your readers, the FE, the RE, to mainstream science, that you do not accept what was published, and it doesn't work like that.

Here you will have to accept your defeat: if you do not want to do that, you are free to visit another forum, or do something else in your life.

The Sagnac effect and pure geometry

American Journal of Physics 83, 427 (2015)

The section itself is entitled SAGNAC EFFECT WITHOUT ROTATION:

(https://image.ibb.co/cPs5vd/sagnac3.jpg)
(https://image.ibb.co/m86n8y/sagnac4.jpg)

The SAGNAC EFFECT is a change in propagation time for light going in a closed path.

That closed path/interferometer can then be rotated, as in the Michelson-Gale experiment.

That is the basic formula derived by the authors who clearly spell out, even for you, what is going on: the paper is called The Sagnac Effect and Pure Geometry.


Most importantly is the following fact:

NO ENCLOSED AREA APPEARS IN THIS EXPRESSION.

Your formula, by contrast, has an area:

dt = 4ωA/c^2

This formula, featuring an area, is the CORIOLIS EFFECT formula:


https://www.ias.ac.in/article/fulltext/pram/087/05/0071

Spinning Earth and its Coriolis effect on the circuital light beams

The final formula is this:

dt = 4ωA/c^2


Since you cannot accept this fact, you have been trolling for the past months this forum.

No more.


Either you accept that the SAGNAC EFFECT formula does not include the area, or leave.


My formula:

(https://image.ibb.co/dbZ7Kd/gsac2.jpg)

The same formula was derived by Professor Yeh:

Using a phase-conjugate mirror, for the first time in 1986, Professor Yeh was able to derive the TRUE SAGNAC FORMULA which is proportional to the velocity of the light beams.


(https://i.ibb.co/6Y9W45j/yeh5.jpg)

page 152 of the pdf document, section Recent Advances in Photorefractive Nonlinear Optics page 4

The MPPC acts like a normal mirror and Sagnac interferometry is obtained.

Here is the derivation of my formula, using TWO LOOPS:

https://www.theflatearthsociety.org/forum/index.php?topic=30499.msg2117351#msg2117351

Here is the final formula:

2(V1L1 + V2L2)/c2

My formula is confirmed at the highest possible scientific level, having been published in the best OPTICS journal in the world, Journal of Optics Letters, and it is used by the US NAVAL RESEARCH OFFICE, Physics Division.

Exactly the formula obtained by Professor Yeh:

φ = -2(φ2 - φ1) = 4π(R1L1 + R2L2)Ω/λc = 4π(V1L1 + V2L2)/λc

Since Δφ = 2πc/λ x Δt, Δt = 2(R1L1 + R2L2)Ω/c2 = 2(V1L1 + V2L2)/c2

CORRECT SAGNAC FORMULA:

2(V1L1 + V2L2)/c2

The very same formula obtained for a Sagnac interferometer which features two different lengths and two different velocities.

If so, see if you can answer this one:

Also, if you would like to appeal to scientific papers so much, how about this one:
https://doi.org/10.1088/0143-0807/38/1/015301

Some key points from it:
The Sagnac phase shift is given by this formula:
(https://i.imgur.com/EDwx4DM.png)
Note that this is different from mine for a few reasons.
Firstly, it is focusing on the phase of the wave not the time shift.
To go from a time shift to the phase, you need to multiply the time by 2*pi*c/lambda (note: This isn't just me saying you multiply by that, the paper states it as well:(https://i.imgur.com/CzOyVk5.png)).
The other distinction is that they are using an interferometer with multiple loops and thus multiplying by the number of loops (N).

As such, this is equivalent to my formula.
So this reference agrees with me, that the phase shift is given by:
dt=4*A*w/c^2.

They also point out that this can be derived by integrating the individual parts over a loop, showing that there is nothing wrong with one of my earlier derivations (which produces an identical result) that first found the phase shift for the individual arms and then added those phase shifts together.

But perhaps the best part is this:
Quote
The results confirmed that the interference phase shift is indifferent to the position of the rotation axis relative to the interferometer area principal axis.
Do you know what that means?
If 4*A*w/c^2 is the Sagnac shift for an interferometer, that is it, regardless of where it is positioned. It doesn't matter if it rotates about it's centre, or a point off centre in the ring, or a point completely outside the ring. It's shift will remain as 4*A*w/c^2.

i.e. I am correct.

So are you going to accept mainstream science?
Will you accept respected, peer-reviewed scientific papers?
Will you accept a peer-reviewed paper, published in a mainstream scientific journal?
Otherwise, in your own words:
By having refused to accept a peer-reviewed paper, published in a mainstream scientific journal, you are thereby trolling this forum.

They derive TWO FORMULAS for the same phenomenon.

Δt = 4Aω/c^2

A = area enclosed by the path of the light beams


Then, the authors derive A SECOND FORMULA for the Sagnac effect, which DOES NOT feature an area:

(https://image.ibb.co/cPs5vd/sagnac3.jpg)
(https://image.ibb.co/m86n8y/sagnac4.jpg)

This formula does not include the area at all, and is proportional to the VELOCITY of the light beams (and thus is proportional to the RADIUS of rotation).


Two different formulas, featuring two different physical descriptions.

This means that the formulas must be describing TWO DIFFERENT PHYSICAL PHENOMENA.


The first formula, which displays the AREA of the interferometer, is actually the CORIOLIS EFFECT formula:

The final formula is this:

dt = 4ωA/c^2


What is the corresponding formula for the Michelson-Gale interferometer which does not display an area and which is proportional to the velocity of the light beams?

Obviously, we now have to deal with two velocities for each side of the interferometer, v1 and v2, not to mention the two different lengths of each side.


Tartaglia and Ruggiero derived TWO formulas for the same phenomenon, but which obviously carry two very different physical and mathematical characteristics: one is proportional to the area of the interferometer, the other one is not.


Here, then, is the correct derivation of the SECOND FORMULA, which does not feature an area, for the Michelson-Gale interferometer:

You are barking up the wrong tree.
Again, projection wont help you.

My formula coincides exactly with the formula derived by Professor Yeh.
No, it is nothing like it.
The formula you are appealing to is for a fibre optic conveyor where the source/detector moves relative to the light path. It does not apply to a rotating ring interferometer.
Also note that Professor Yeh's formula contains only a single length and a single velocity, not the 2 you have.

What you are appealing to does not apply to what we are discussing.
As such, I have no need to write to any of them regarding the Sagnac effect.

Once we deal with an interferometer we can move on to the generalised Sagnac effect for a FOC.

Now can you address the several issues raised regarding this issue?
You need to refute my derivation which you have been unable to show any problem with.
You need to explain why you are finding the difference in time taken for a single beam of light, which corresponds to nothing in reality, and pretending it is the total time taken.
You need to explain why an interferometer which isn't rotating at all and instead is moving with uniform linear motion has a Sagnac shift, when symmetry demands it can't (and my formula says it can't, and the formula produced by so many people says it can't).

I notice you are just completely ignoring them and just reposting the same spam.

Do I need to start with simple questions again?

https://web.infn.it/GINGER/administrator/components/com_jresearch/files/publications/sagnac_AJP.pdf (pages 5-6)
No, it hasn't.
As I pointed out before, this has the detector/source move relative to the ring.
It is not the entire interferometer moving as one.
This is perhaps shown most clearly in figure 7.
With this you see the path remain fixed, while the source/detector (labelled the observer) moves.
It even explicitly states that the observer is in 2 positions relative to the ring, with one position at the start when the light is sent and the other at the end when the light is received.
It also shows the path of the light and how the light does not completely traverse the ring.

So no, this is a FOC where the source/detector moves relative to the light path. It is not a simple ring interferometer where the interferometer moves as one with uniform linear motion.

Ignoring what the paper shows to try and avoid answering questions/addressing massive problems with your claims will not help you.

Also note, the paper I used does apply.
It is referring to a ring interferometer.
It shows and states quite explicitly that it doesn't matter where the centre of rotation is, the shift will be the same and it is proportional to the area and angular velocity.

The authors of that paper have derived the CORIOLIS EFFECT formula, not the SAGNAC EFFECT formula.
No, they didn't.
Read the paper.
No where in it does it mention the Coriolis effect.
You are rejecting a peer-reviewed paper, published in a mainstream scientific journal, all because it shows you are wrong.

So how shall I put this? How about I just use your words again:
You either accept these published results or you don't.
If you do not want to accept them, you have two basic choices: write to the journals and let them know of your learned opinion, or leave this forum.

How can anyone call a formula which evidently has two velocities incorporated into the final equation, as a formula which has "only one velocity"?


Of course the paper referenced by you does not mention the CORIOLIS EFFECT, since Dr. Eyal Schwartz does not understand the issues involved regarding the fact that the SAGNAC EFFECT does not feature an area.

Obviously, the SAGNAC EFFECT must have a different formula which does not feature an area.

And this I have proved right here:

The SAGNAC EFFECT does not feature an area.

NOTE TO THE MODS/ADMIN:

What are we going to do with this user? He is trolling this forum unabated, using basic spamming as his main instrument of "debating".

He has just been shown where he went wrong, yet he will have none of it.

He is describing a formula which has two velocities, as a formula which has only one velocity.

Is this not trolling at its worst?

You are having an emotional breakdown and this is not the place to cure it.

In such a distressed state, you are not thinking clearly at all.

Also note that Professor Yeh's formula contains only a single length and a single velocity, not the 2 you have.

(https://i.ibb.co/MsS5Bb5/yeh4.jpg)


This is pure trolling on your part.

You have just stated that Professor Yeh's formula contains "only a single length and a single velocity".

But there are TWO LENGTHS, AND THUS TWO VELOCITIES in the formula.

Clearly spelled out in front of you.


As did Professor Yeh's

“R1,2 and L1,2 are the lengths and radii of the fiber loops”

You are having an emotional breakdown and this is not the place to cure it.
Again, projecting will not help you.

You need to deal with the issues raised.

But there are TWO LENGTHS, AND THUS TWO VELOCITIES in the formula.
My bad, I thought you were referring to their work on the FOC, not PCMs, which are no relevance to our discussion.

But you are wrong again. There is no velocity in that formula. Instead there is an angular velocity.
Also note that with the schematic shown, the 2 loops are not concentric and there is no stated requirement for the loops be aligned with the axis of rotation.
As a result, this angular velocity cannot be converted into 2 tangential velocities. Instead, each point on each loop would have their own velocities. So it would be an infinite number, not 2.
You can convert it to a tangential speed if you have the 2 loops being concentric and have the centre match the axis of rotation, but then you have a single speed, not to.

So no matter how you try and pretend, it is not 2 velocities.
So it still contradicts your claim.

Can everyone see what is going here?
I'm sure most people can.

Since you cannot accept defeat, you are resorting to the same bullshitting methods that you used as well.
You are rejecting accepted scientific papers published in mainstream journals.
You have been refuted and are unable to rationally respond to the objections raised.

How can anyone call a formula which evidently has a single angular velocity for 2 loops incorporated into the final equation, as a formula which has "two velocities"?

Of course the paper referenced by you does not mention the CORIOLIS EFFECT, since Dr. Eyal Schwartz does not understand the issues involved regarding the fact that the SAGNAC EFFECT does not feature an area.
Then like you said:
You either accept these published results or you don't.
If you do not want to accept them, you have two basic choices: write to the journals and let them know of your learned opinion, or leave this forum.
If you continue on this path here, it will be assumed that you are trolling this forum.
Go ahead and write to those journals, let them know of your opinion, and then come back here in several months.
Otherwise, you presence here will be taken as trolling this forum.

So are you going to accept their result? Or will you right to them to object?

The simple reality is that he experimentally measured what the actual shift is.
What you call it is irrelevant.
What the ultimate cause is is irrelevant.
The simple fact is that this is the shift which is observed in reality for a rotating interferometer and as clearly shown by this paper, it doesn't matter where the centre of rotation is.

So like you said, accept the published scientific work, or go write to the paper and complain.


Or, you can stop with those pathetic appeals to authority and actually discuss the issues raised.
Again:
You need to refute my derivation which you have been unable to show any problem with.
You need to explain why you are finding the difference in time taken for a single beam of light, which corresponds to nothing in reality, and pretending it is the total time taken.
You need to explain why an interferometer which isn't rotating at all and instead is moving with uniform linear motion has a Sagnac shift, when symmetry demands it can't (and my formula says it can't, and the formula produced by so many people says it can't).

Do I need to start with simple questions again?

If so, see if you can answer this one (and answer it correctly, without misrepresenting a FOC where the source/detector moves relative to the ring as the entire thing moving as one):
If we take a rectangular interferometer and have it undergo uniform linear motion, with the entire interferometer moving as one, should we expect any Sagnac phase shift?
If so, which beam is faster, the clockwise beam or the counter clockwise beam?

You derived a formula, namely this one:

But this is the CORIOLIS EFFECT formula:

The final formula is this:

Very simple, yet you are trolling on a daily basis, failing to understand this very easy to understand point.


At this point in time, there is nothing to discuss here, nothing about the SAGNAC EFFECT: I have just proven that your formula is actually the CORIOLIS EFFECT equation.


Have you forgotten the definition of linear velocity?

v = RΩ

φ = -2(φ2 - φ1) = 4π(R1L1 + R2L2)Ω/λc = 4π(V1L1 + V2L2)/λc

Since Δφ = 2πc/λ x Δt, Δt = 2(R1L1 + R2L2)Ω/c2 = 2(V1L1 + V2L2)/c2

CORRECT SAGNAC FORMULA:

2(V1L1 + V2L2)/c2

Both Professor Yeh and myself have derived the SAME FORMULA.


You are trying to deflect attention from your utter failure to explain this very simple points by inventing all sorts of demands, all of which have been addressed amply before.

So you are trolling. Yet again.


Here is the mother of all SAGNAC EFFECT references:

http://www.orgonelab.org/EtherDrift/Post1967.pdf

But even E.J. Post makes the same mistake as all other physicists: he calls the formula which features an area as the Sagnac effect, which it is not; it is actually the CORIOLIS EFFECT formula.


The SAGNAC EFFECT does not include the area in its formula.

My incursion in the scienceforums debate proved one thing: it is a good thing they closed that thread, because otherwise I would have demolished their forum.

They had no arguments to debate the SAGNAC EFFECT with me.

The policy over on the scienceforums is this: anyone who dares to state anything against TGR/TSR is moved to the bottom of the barrel section, where you are not allowed to say much, because they close the threads right away.

However, for the period my thread was open, I was able to prove that their knowledge of the subject was woefully inadequate to even dream to debate with me.

What do you think is going to happen to you stash if you get the wild idea that you can debate with me not only the SAGNAC EFFECT but any other FE vs RE subject? Make no mistake about it, I will demolish your beliefs in less than 20 seconds.


edit

I was the one who brought the link to the scienceforums debate here in the FED section, not too long ago.

So, what you posted is actually old news.

Since the OP appears impervious to reason and genuine scientific rebuttal, this thread is closed.

Fine.

Why then, were they not able to explain the facts which were clearly exposed in that thread? You see, they failed to answer the fact that the formula for the CORIOLIS EFFECT includes the area, but not the SAGNAC EFFECT formula.

When did they actually close the thread? The minute I posted the passage which proved that the Sagnac effect is not related to the area of the interferometer.

You might also notice THE SAME KIND of trolling, on their own turf, exhibited here by the RE.

Post by: JackBlack on October 01, 2019, 03:44:05 AM
You are not addressing the main issues here.
No, I have addressed it quite explicitly.
I have provided my own derivation, yet again, clearly explaining each step.
I have provided a scientific journal article to back up my claim, which even uses experimental data to show that the Sagnac effect is as I say.
I have dealt with your derivation, clearly explaining why it is wrong. As a reminder, your derivation is wrong because when trying to find a total time for the a beam of light, you instead find a time difference, which corresponds to nothing in reality.
I have also provided a simple example which shows your formula is wrong, as it predicts a shift when there should be none.
I have also explained why the vast majority of the articles you bring up do not apply, as they are discussing a different issue (e.g. a FOC not a rotating ring interferometer).

Meanwhile you have repeatedly avoided very simple questions.

You are the one not addressing the main issues here.

If you want to try addressing them, then stop with the semantics, stop bringing up FOCs and PCMS and deal with a simple ring interferometer.

Address the issues raised:
Again:
You need to refute my derivation which you have been unable to show any problem with.
You need to explain why you are finding the difference in time taken for a single beam of light, which corresponds to nothing in reality, and pretending it is the total time taken.
You need to explain why an interferometer which isn't rotating at all and instead is moving with uniform linear motion has a Sagnac shift, when symmetry demands it can't (and my formula says it can't, and the formula produced by so many people says it can't).

Do I need to start with simple questions again?

If so, see if you can answer this one (and answer it correctly, without misrepresenting a FOC where the source/detector moves relative to the ring as the entire thing moving as one):
If we take a rectangular interferometer and have it undergo uniform linear motion, with the entire interferometer moving as one, should we expect any Sagnac phase shift?
If so, which beam is faster, the clockwise beam or the counter clockwise beam?

But this is the CORIOLIS EFFECT formula:
This is nothing more than pure semantics.
Have you even bothered reading that paper?
That paper of yours claims that this is not actually the Sagnac effect and instead is just the Coriolis effect. It is not saying that the Sagnac effect is something different. It is saying what is known as the Sagnac effect is actually just the Coriolis effect.

If you want to call it the Coriolis effect instead, then go ahead, but the same arguments apply. Your formula is still wrong. The formula for the actual shift observed will remain as 4*A*w/c^2.

Have you forgotten the definition of linear velocity?
No, have you?
I assume you are talking about tangential velocity?
This is given by the product of the angular velocity and the distance from the centre of rotation.
That part is quite important.
If you have a loop which is not concentric with the centre of rotation (such as in Yeh's paper), then you CANNOT just use the radius.

Also, have you forgotten the definition of area for a circular sector?
A=R*l, so just like you want to pretend the formula uses velocity, it can likewise be claimed to use area.
So your claim that it uses a linear velocity is less valid than the reality of it using an area.

But as I already pointed out, the interferometer in that paper is nothing like what we are discussing and as such is irrelevant.

Both Professor Yeh and myself have derived the SAME FORMULA.
No, you don't. You have a different formula, and like I said, it is a different interferometer. As such it is irrelevant.

You are trying to deflect attention from your utter failure to explain this very simple points
You mean like your failure to explain what your time difference between the arms is meant to represent?
Or why you feel the need to change the sign for a time when it travels backwards along the arm, which would only make sense if it also went backwards in time?

Again, stop projecting, it wont help.

Here is the mother of all SAGNAC EFFECT references:
http://www.orgonelab.org/EtherDrift/Post1967.pdf
And have you bothered reading it?
Have you noted that it again agrees with me, not you?

It states that the shift is proportional to the area and angular velocity.

So if you want to use that go ahead and accept that you were wrong.

Once again, you are rejecting well established science, while complaigning about others allegedly doing so, when the others are just refusing to accept your baseless claims about the science.

See how easy it is to defeat you?
Well it seems to be completley impossible for you.
You are yet to address any of the points raised.
Instead you have just repeated the same refuted spam.

Again, if you want to defeat me you need to do the following:
You need to refute my derivation which you have been unable to show any problem with.
You need to explain why you are finding the difference in time taken for a single beam of light, which corresponds to nothing in reality, and pretending it is the total time taken.
You need to explain why an interferometer which isn't rotating at all and instead is moving with uniform linear motion has a Sagnac shift, when symmetry demands it can't (and my formula says it can't, and the formula produced by so many people says it can't).

And no, appealing to a bunch of papers which are not related to the interferometer we are discussing will not help you.
Appealing to papers which you then attack and say they got it wrong will not help you.

Either accept the papers from the scientific community in their entirety, which means accepting that the Sagnac shift for a rotating ring interferometer with normal mirrors is given by dt=4*A*w/c^2, regardless of the geometry of the ring or if it is rotating about its centre or rotating about some other point; or stop using papers entirely and defend your claims yourself.

You must go back to high school to study physics.

THE CORIOLIS EFFECT AND THE SAGNAC EFFECT ARE TWO TOTALLY DIFFERENT PHYSICAL PHENOMENA.

The Coriolis effect is a physical effect on the light beams proportional to the area of the interferometer) and the SAGNAC EFFECT (an electromagnetic effect proportional to the radius of the rotation).

One is a PHYSICAL EFFECT: the Coriolis effect.

The other is an ELECTROMAGNETIC EFFECT: the Sagnac effect.

You have just stated that you do not know physics at all jackblack.


Two different phenomena require TWO DIFFERENT FORMULAS.

If you have a loop which is not concentric with the centre of rotation (such as in Yeh's paper), then you CANNOT just use the radius.

WHAT ?!

The interferometer (a ring laser interferometer as an example or the MGX) is rotated around a certain axis (center of the Earth). You have a radius connecting that center with the sides of the interferometer, and also an angular velocity of rotation. You multiply the radius by the angular velocity and you get your linear velocity very easily.

Since the formulas are the same, mine and Professor Yeh's formula, it means the same situation applies to both cases.

Very easy to understand.

No, I haven't.
The formula I derived is the Sagnac effect formula.
The paper you are appealing to claims that what is known as the Sagnac effect is just the Coriolis effect.
If you want to call it the Coriolis effect, go ahead. I will continue to call it the Sagnac effect, as it is called in the mainstream scientific literature. (you know, like by all those papers you claim get it wrong)


BUT NOT THE SAGNAC EFFECT.
Ignoring reality wont help you.
I have already provided the proof in the form of a derivation of the shift and with scientific papers, including the ones you have appealed to.
The shift, for a rotating ring itnterferometer is proportional to the area, not the linear velocity.
A FOC has a different formula due to the fundamental difference between it and the rotating ring interferometer.

If you have a loop which is not concentric with the centre of rotation (such as in Yeh's paper), then you CANNOT just use the radius.
WHAT ?!
That is a fairly simple statement to understand.
In the formula you are appealing to from Yeh, they use the radius and length (the product of which gives area), and an angular velocity. This can be simplified to an area and an angular velocity which you outright reject. You instead want to pretend that you can use this angular velocity and radius to get a linear velocity even though is absolutely no requirement for the loops to be concentric with the centre of rotation. That means you cannot use the radius. Instead you need to use the distance from the centre. That means Yeh's formula is not like yours. It does not provide 2 lengths and 2 linear velocities.
It is a different formula.

Also note that it is nothing like the interferometer being discussed.

Now, I am going to celebrate my total victory here.
Perhaps you should try achieving a small victory first.
Start by dealing with what you need to do to obtain a victory:
You need to refute my derivation which you have been unable to show any problem with.
You need to explain why you are finding the difference in time taken for a single beam of light, which corresponds to nothing in reality, and pretending it is the total time taken.
You need to explain why an interferometer which isn't rotating at all and instead is moving with uniform linear motion has a Sagnac shift, when symmetry demands it can't (and my formula says it can't, and the formula produced by so many people says it can't).


Just repeatedly asserting my derivation is wrong, without being able to show a single problem wont help. Nor will appealing to scientific papers, when you reject scientific papers.
You need to show an actual problem with the derivation.

So far you have no chance of victory as you haven't even attempted to address these massive issues with your claims.

This can be simplified to an area and an angular velocity

There is no area in the interferometer used by Professor Yeh: just a segment connecting two mirrors.

φ = -2(φ2 - φ1) = 4π(R1L1 + R2L2)Ω/λc = 4π(V1L1 + V2L2)/λc

Since Δφ = 2πc/λ x Δt, Δt = 2(R1L1 + R2L2)Ω/c2 = 2(V1L1 + V2L2)/c2

CORRECT SAGNAC FORMULA:

2(V1L1 + V2L2)/c2


MORE PROOFS THAT THE SAGNAC EFFECT DOES NOT FEATURE AN AREA.

SAGNAC EFFECT WITHOUT AN AREA OR A LOOP

https://arxiv.org/ftp/physics/papers/0609/0609202.pdf

The use of a phase-conjugate mirror has permitted new breakthroughs in the experimental science of the Sagnac effect.

page 152 of the pdf document, section Recent Advances in Photorefractive Nonlinear Optics page 4

The MPPC acts like a normal mirror and Sagnac interferometry is obtained.

(https://image.ibb.co/g629jS/lis5.jpg)

The equation which expresses the relationship between interference fringes and time differences is F=dt[c/λ] (where dt = 4vL/c2).

This experiment shows us two important points. First, it confirms the phase reversal of a PCM and demonstrates the Sagnac effect in an arc segment AB, not a closed path. Second, it gives us important implications: The result, φ = 4πRΩL/cλ, can be re-written as φ = 4πvL/cλ where v is the speed of the moving arc segment AB (where R is the radius of the circular motion, Ω is the rotational rate).

If we increase the radius of the circular motion as shown in Fig. 6, the arc segment AB will approach a linear segment AB, the circular motion will approach the linear motion, the phase-conjugate Sagnac experiment will approach the phase-conjugate first-order experiment as shown in Fig. 4, and the phase shift is always φ = 4πvL/cλ.


The Sagnac effect for a ROTATING LINEAR SEGMENT interferometer IS: 2vL/c2, where v=RΩ.

It doesn't work like that. You lying about what I did wont magically change reality to match your fantasy.

It can't be, since you admitted minutes ago that the formula you derived is the CORIOLIS EFFECT formula.
Again, I did no such thing. Can you read English? I said that they (i.e. the authors of the paper you are appealing to) said it was. I did not say that I said it was that.

Now again, how about you stop with all the semantic BS and deal with the issues raised?
And no, running off onto yet another tangent, to discuss yet another type of interferometer will not help.

But lets see what you bring now:
The shift, for a rotating ring itnterferometer is proportional to the area, not the linear velocity.
For the SAGNAC EFFECT there is no area.
https://web.infn.it/GINGER/administrator/components/com_jresearch/files/publications/sagnac_AJP.pdf
Again, if you want to appeal to scientific literature, you have already lost. I have already provided a paper which shows that it is proportional to the area.

But don't worry, this reference of yours still supports me.
Tell me, what is its equation 2?
Is it the time difference, given as 4*A*w/c^2?

So yet again, your own references show you are wrong.

The "generalised Sagnac effect" for a FOC may be based upon a velocity, but for a simple rotating ring interferometer with normal mirrors it is based upon the area and angular velocity.

If you wish to disagree, provide a reference which states anything like what you claim for a normal rotating ring interferometer, not a FOC.

There is no area in the interferometer used by Professor Yeh: just a segment connecting two mirrors.
Sure, just "a segment" which is wound into a loop which encloses an area.
This are is given by l*r, i.e. the circumference times the radius.

Stop manipulating their formula into something it isn't.
There formula does not use any linear velocity.
It only has angular velocity.

Like I said before (and you ignored), you can only convert between them with the distance from the centre of rotation. Instead of doing that you are using the radius of the loop.
That requires both loops, clearly shown in 2 separate locations, to be concentric, a direct contradiction.

Meanwhile, the conversion from the circumference and radius to the area is always correct.
The one caveat is that if you increase the number of loops, it is the effective area which is the area of 1 loop multiplied by the number of loops.

That means your claims about the formula are pure nonsense as R1Ω is not the same as V1.
You wold need to calculate the velocity for each tiny component of the loop, and that needs the distance to the centre of rotation, not the centre of the loop.

Meanwhile, my claims about the formula are perfectly correct:

φ = -2(φ2 - φ1) = 4π(R1L1+R2L2)Ω/λc = 4π(A1+A2)Ω/λc
Since Δφ = 2πc/λ x Δt, Δt = 2(A1+ A2)Ω/c2

A nice thing to note, is that if you do make the 2 rings concentric and the same size, then A=A1=A2
and you are left with:
Δt = 4 A Ω/c2

But like I said, this uses a PCM. It is not the interferometer we are discussing.
So it is just a tangent. A distraction from the real issue.

The use of a phase-conjugate mirror has permitted new breakthroughs in the experimental science of the Sagnac effect.
No it hasn't.
All you have provided is a non-peer reviewed claim, which relies upon unproven assumptions about how a PCM works, with absolutely no experimental backing.

That is not a breakthrough in any sense of the word.

But again, it uses a PCM, and thus is irrelavent to the discussion.

Now how about you address the points you have been repeatedly avoiding?

You need to refute my derivation which you have been unable to show any problem with.
You need to explain why you are finding the difference in time taken for a single beam of light, which corresponds to nothing in reality, and pretending it is the total time taken.
You need to explain why an interferometer which isn't rotating at all and instead is moving with uniform linear motion has a Sagnac shift, when symmetry demands it can't (and my formula says it can't, and the formula produced by so many people says it can't).

Today it has been jackblack's worst disaster to date, his worst day performance ever.

A total victory for FE.

It can't get worse than this for him.

jackblack has just admitted he is a FLAT EARTH BELIEVER.


He has even lost control of what he is saying now.


It can't be, since you admitted minutes ago that the formula you derived is the CORIOLIS EFFECT formula.
I did not say that I said it was that.

Come again?

But you did say that you said it was that.



But this is the CORIOLIS EFFECT formula:
This is nothing more than pure semantics.
Have you even bothered reading that paper?
That paper of yours claims that this is not actually the Sagnac effect and instead is just the Coriolis effect. It is not saying that the Sagnac effect is something different. It is saying what is known as the Sagnac effect is actually just the Coriolis effect.

If you want to call it the Coriolis effect instead, then go ahead, but the same arguments apply. Your formula is still wrong. The formula for the actual shift observed will remain as 4*A*w/c^2.


It is saying what is known as the Sagnac effect is actually just the Coriolis effect.


There is no going back for you now.


But this is the CORIOLIS EFFECT formula:

It is saying what is known as the Sagnac effect is actually just the Coriolis effect.

YOU HAVE JUST ADMITTED THAT YOUR FORMULA IS ACTUALLY THE CORIOLIS EFFECT FORMULA.


YOU HAVE TROLLED THIS FORUM FOR ABSOLUTELY NOTHING AT ALL.


You derived a formula, namely this one:

dt = 4ωA/c^2


But this is the CORIOLIS EFFECT formula:


https://www.ias.ac.in/article/fulltext/pram/087/05/0071

Spinning Earth and its Coriolis effect on the circuital light beams

The final formula is this:

THIS IS FLAT EARTH DAY FOR SURE!!!


The "generalised Sagnac effect" for a FOC may be based upon a velocity, but for a simple rotating ring interferometer with normal mirrors it is based upon the area and angular velocity.

But again, it uses a PCM, and thus is irrelavent to the discussion.

DID YOU JUST SAY THAT THE SAGNAC EFFECT USING PCMs, FOR A FOC, IS ACTUALLY BASED ON A VELOCITY?

DID YOU?

It seems you just did!

The "generalised Sagnac effect" for a FOC may be based upon a velocity

For your information, PCMs act just like normal mirrors for the SAGNAC EFFECT.

(https://i.ibb.co/6Y9W45j/yeh5.jpg)

The MPPC acts like a normal mirror and Sagnac interferometry is obtained.


Then, you agree that your formula is the CORIOLIS EFFECT formula, and that the SAGNAC EFFECT formula is BASED ON VELOCITY.

Your own words:

The "generalised Sagnac effect" for a FOC may be based upon a velocity


JACKBLACK, ARE YOU STILL AWAKE?

Please go to sleep, here you are only making your disaster that much worse for yourself.

How could you write something like this:

φ = -2(φ2 - φ1) = 4π(R1L1+R2L2)Ω/λc = 4π(A1+A2)Ω/λc
Since Δφ = 2πc/λ x Δt, Δt = 2(A1+ A2)Ω/c2


You multiplied the RADIUS by the LENGTH: there is no area in Professor Yeh's interferometer.

The LENGTH is the length of the segment connecting two mirrors.

The RADIUS is the RADIUS of rotation.

High school physics is too much for you: may I suggest junior high school?

You just multiplied the LENGTH OF THE SEGMENT by the RADIUS: that is NOT THE AREA AT ALL.

There is no actual area in Professor Yeh's interferometer.

You are inventing things as you go along, a sure sign of trolling.


HERE IS PROFESSOR WANG TELLING YOU THAT IF YOU MULTIPLY THE RADIUS BY THE ANGULAR VELOCITY YOU DO GET THE LINEAR VELOCITY:

(https://image.ibb.co/g629jS/lis5.jpg)

The equation which expresses the relationship between interference fringes and time differences is F=dt[c/λ] (where dt = 4vL/c2).

This experiment shows us two important points. First, it confirms the phase reversal of a PCM and demonstrates the Sagnac effect in an arc segment AB, not a closed path. Second, it gives us important implications: The result, φ = 4πRΩL/cλ, can be re-written as φ = 4πvL/cλ where v is the speed of the moving arc segment AB (where R is the radius of the circular motion, Ω is the rotational rate).

If we increase the radius of the circular motion as shown in Fig. 6, the arc segment AB will approach a linear segment AB, the circular motion will approach the linear motion, the phase-conjugate Sagnac experiment will approach the phase-conjugate first-order experiment as shown in Fig. 4, and the phase shift is always φ = 4πvL/cλ.


The result, φ = 4πRΩL/cλ, can be re-written as φ = 4πvL/cλ


Professor Wang multiplies the radius by the angular velocity, AND NOT THE RADIUS BY THE LENGTH, like you have catastrophically just done.


You are history here jackblack.

This is exactly what I have been saying here for months.

You have trolled this forum for no reason at all.

Now, finally, you admit I was right and that you were wrong.

Again, projecting wont help. How many times must this be said?

It seems you are completely refusing to engage in any form of rational debate.
Instead you just want to repeatedly lie about what I said and continue to use irrelevancies to avoid actual debate.

Time to just start skipping your spam, as you have shown humouring it will not help at all.

How could you write something like this:
φ = -2(φ2 - φ1) = 4π(R1L1+R2L2)Ω/λc = 4π(A1+A2)Ω/λc
Since Δφ = 2πc/λ x Δt, Δt = 2(A1+ A2)Ω/c2

You multiplied the RADIUS by the LENGTH: there is no area in Professor Yeh's interferometer.
My bad, I left out a factor of 2. The radius time the length is 2 times the area, not the area.
We all make mistakes.
Because there are 2 loops you get 2 times the shift, one for each loop.

Remember some basic high school math?
For a circle with radius r, the area is pi*r^2, and the circumference is 2*pi*r.
So this means l (the circumference) multiplied by the radius gives 2*pi*r*r, i.e. 2* the area.

Sure, it could be done as a fibre coil instead of a loop for more accuracy, in which case l=2*pi*r*N, where N is the number of coils.
But that just equates to 2*N*A, where N*A gives the effective area of the loop.
It is still based upon the area and the angular velocity.

So my substitution is perfectly valid.
If you wish to reject this maths please show exactly where it is wrong.
Do you disagree that the area of a circle is pi*r^2?
Do you disagree that the circumference of a circle is 2*pi*r?
Do you disagree that for a coil, the length of the coil is 2*pi*r*N?

If you don't object to one of those points, you have no grounds to object to the shift being proportional to the product of the area and angular velocity.

The LENGTH is the length of the segment connecting two mirrors.
The RADIUS is the RADIUS of rotation.
No it isn't.
Have you read the paper you are blatantly lying about?
However, as you aren't even bothering to link to that paper, have you realised that it doesn't support you and you are now trying to bury it?
Don't worry, you posted a picture before which has enough:
(https://i.ibb.co/MsS5Bb5/yeh4.jpg)
Now, I might not be a genius, but I can read fairly well.
Do you notice what it says at the bottom?
It states quite explicitly that R and L refer to the radius and length of the fibre coils.
They do not refer to the radius of rotation (which would vary throughout the instrument and thus cannot be a single value anyway, did you skip that lesson in physics?) nor to the length of the fibre segment between the mirrors.
So stop lying.
Start honestly presenting your references.

In order to do so that means accepting that the formula does not feature any linear velocity. Instead it features the radius and length of a fibre coil which gives the area and number of turns, as well as an angular velocity.
Just like all the valid references say for a rotating ring interferometer and completely unlike what you claim.

For a circular loop, r*l can always be substituted for 2*A, for a coil, it is 2*N*A.
r*w can only be substituted for the tangential speed when it is rotating about its centre.

So once again, you have no victory.

If you want it, stop with the spam.
Just focus on simple interferometer with normal mirrors and deal with the issues raised:
You need to refute my derivation which you have been unable to show any problem with.
You need to explain why you are finding the difference in time taken for a single beam of light, which corresponds to nothing in reality, and pretending it is the total time taken.
You need to explain why an interferometer which isn't rotating at all and instead is moving with uniform linear motion has a Sagnac shift, when symmetry demands it can't (and my formula says it can't, and the formula produced by so many people says it can't).

Post by: Stash on October 01, 2019, 01:48:45 PM
I found this a particularly interesting read regarding how the Sagnac effect is very well explained using Special Relativity:

"There is a mythology among many modern crackpots that Sagnac's result was a refutation of special relativity, and that therefore the effect was for decades ignored by the scientific community. This mythology is both technically and historically untrue. First, as noted above, Sagnac’s conclusion was simply that the speed of light is independent of the source, a fact which is in perfect accord with special relativity. Second, when someone named Paul Harzer published a note in 1914 suggesting that the effect (referring to Harress’s work on light propagating in a rotating medium) was inconsistent with special relativity, Einstein immediately (July 1914) responded in the same journal, clearly explaining the fallacy in Harzer’s reasoning:

Mr. Harzer states that in accordance with relativity theory the convection coefficient (1c) is to be expected, while he finds from the experiment of Harress that the results are in accordance with convection coefficients (1b).  A view of the Harress arrangement shows however that it quite concerns the case (1b) here, so the experiment as well as Harzer’s calculation supplies not a refutation but, to the contrary, a confirmation of the theory.

Everyone familiar with special relativity, even critics such as Michelson, always recognized that the Sagnac effect is a (rather trivial) confirmation of special relativity, not a refutation.

Another part of the anti-relativityist mythology is the idea that the Michelson-Gale measurement of the Earth’s rotation in 1924 by means of the Sagnac effect refutes special relativity, and/or was viewed as such at the time. This again is utterly false, both technically (for the reason given above) and historically. The measurement was first considered by Michelson around 1905, but he realized it would not discriminate between the predictions of special relativity and those of a stationary ether theory (with no drag), so he did not pursue it. The idea was raised again, by a certain Dr. Ludwig Silberstein, in 1921 during Einstein’s visit to the United States. According to the rather breathless account given in the New York Times for May 12:

A proposal for an experiment which may prove Einstein's theory of relativity to be all wrong has been placed before scientific men here to attend Professor Einstein's lectures, and it has aroused the greatest interest. This is to test the pull of the rotating earth upon the ether to learn whether there is a drag, whole or partial, and it has several possible results, the most important of which is its effect on the theory of relativity. So important is the experiment judged to be by those who have learned of it that Professor Albert A. Michelson… has offered to perform the experiment. Professor Einstein was informed of it three days ago, and at first was inclined to doubt that it would have any bearing on his theory, but, after thinking it over, has decided that it is a new and practical way of testing his theory, and has described it as "wonderful." … Based on the ether theory the effect should be either equal to the full value [of the Sagnac effect], if there is no dragging of the ether by the spinning earth, and no effect at all if there is a full drag. Finally there would be only a fraction of the full effect if there is a partial dragging of the ether by the spinning earth. If, therefore, the experiment which Professor Michelson will perform gives a full value of the shift, this will harmonize with the general relativity theory as well as with the ether theory, but if the effect is nil, or only a fraction of the full shift of 1.4 per square kilometer, it will be "a death blow to the relativity theory," although compatible with the ether theory, testifying simply to a partial drag… Professor Einstein … said he would gladly recognize a fractional shift as a blow to his theory, and at the same time enjoy the demonstration of the novel phenomena. However, both Dr. Silberstein and Professor Einstein believe that the full shift effect will be shown.

Needless to say, when the measurement was actually performed, the full shift was observed, as Silberstein, Einstein, and Michelson had all known it would be, thereby demonstrating yet another phenomenon consistent with relativity. It would be fascinating to know how these mundane facts, which plainly describe a confirmation of relativity theory, came to be adopted into the anti-relativityist folklore as a canonical refutation of relativity.

Of course, as was obvious to Michelson and Einstein all along, this measurement [which was performed in as near to vacuum as possible) does not discriminate between relativity and a perfectly un-dragged ether, so it is a rather trivial confirmation of special relativity. However, it is also possible to perform such a measurement in a medium with an index of refraction differing from 1. Indeed many ordinary Sagnac devices using fiber optic lines and therefore actually involve the Fizeau effect as well as the Sagnac effect, because they run light in opposite directions through a rotating medium with an index of refraction differing significantly from 1. In order to account for the results in this kind of device, an etherist needs to invoke, at the very least, Fresnel's partial dragging hypothesis (whereas he needs to deny any dragging at all to account for the full shift measured in vacuum). This makes the device a somewhat less trivial confirmation of special relativity, because the Fizeau effect is not trivial. This is seldom mentioned in discussions of the Sagnac effect, perhaps justifiably, because the "pure" Sagnac effect consists of the path dependence of the optical path length with respect to a rotating system, as distinct from the Fizeau effect of light propagating in a moving medium. Nevertheless, both of these effects are present in many real Sagnac devices."

Much worse than yesterday.

jackblack is NO MORE.

After what happened to you yesterday, nobody here will ever care about anything you write, the fisking, the constant trolling, the desperate attempts to satisfy the cognitive dissonance.

You seem to be the last one to understand these very obvious things.


Here is what you have just admitted just a few hours ago:


But this is the CORIOLIS EFFECT formula:

The SAGNAC EFFECT does not have an area incorporated into the formula.

Here is the proof:

NO ENCLOSED AREA APPEARS IN THIS EXPRESSION.



Here is my formula:

2(V1L1 + V2L2)/c2

Let V1 = R1 x Ω

Let V2 = R2 x Ω

2(R1ΩL1 + R2ΩL2)/c2

=

2(R1L1 + R2L2)Ω/c2

THIS IS THE VERY SAME FORMULA DERIVED BY PROFESSOR YEH:

(https://image.ibb.co/mtGWny/mgrot6.jpg)

φ = -2(φ2 - φ1) = 4π(R1L1 + R2L2)Ω/λc

Since Δφ = 2πc/λ x Δt, Δt = 2(R1L1 + R2L2)Ω/c2

MY FORMULA!


There is no area in the SAGNAC EFFECT formula: in Professor Yeh's experiment one has a segment of fiber connecting two mirrors, that's all.

There is NO CLOSED LOOP, thus no area.

That is why your drivel is useless here.


Here is how the substitution is performed by a real expert in the field, Professor Ruyong Wang:

HERE IS PROFESSOR WANG TELLING YOU THAT IF YOU MULTIPLY THE RADIUS BY THE ANGULAR VELOCITY YOU DO GET THE LINEAR VELOCITY:

Professor Wang multiplies the radius by the angular velocity, AND NOT THE RADIUS BY THE LENGTH, like you have catastrophically just done.


So you lose, yet again.

Post by: sandokhan on October 01, 2019, 02:09:48 PM
stash... is your message supposed to be a joke?

The Sagnac effect is far larger than the effect forecast by relativity theory.

STR has no possible function in explaining the Sagnac effect.

The Sagnac effect is a non-relativistic effect.

COMPARISON OF THE SAGNAC EFFECT WITH SPECIAL RELATIVITY, starts on page 7, calculations/formulas on page 8

http://www.naturalphilosophy.org/pdf/ebooks/Kelly-TimeandtheSpeedofLight.pdf

page 8

Because many investigators claim that the
Sagnac effect is made explicable by using the
Theory of Special Relativity, a comparison of
that theory with the actual test results is given
below. It will be shown that the effects
calculated under these two theories are of very
different orders of magnitude, and that
therefore the Special Theory is of no value in
trying to explain the effect.

COMPARISON OF THE SAGNAC EFFECT WITH STR

STR stipulates that the time t' recorded by an observer moving at velocity v is slower than the time to recorded by a stationary observer, according to:

to = t'γ

where γ = (1 - v2/c2)-1/2 = 1 + v2/2c2 + O(v/c)4...

to = t'(1 + v2/2c2)


dtR = (to - t')/to = v2/(v2 + 2c2)

dtR = relativity time ratio



Now, to - t' = 2πr/c - 2πr/(c + v) = 2πrv/(c + v)c

dt' = to - t' = tov/(c + v)


dtS = (to - t')/to = v/(v + c)


dtS = Sagnac ratio


dtS/dtR = (2c2 + v2)/v(v + c)

When v is small as compared to c, as is the case in all practical experiments, this ratio
reduces to 2c/v.


Thus the Sagnac effect is far larger than any
purely Relativistic effect. For example,
considering the data in the Pogany test (8 ),
where the rim of the disc was moving with a
velocity of 25 m/s, the ratio dtS/dtR is about
1.5 x 10^7. Any attempt to explain the Sagnac
as a Relativistic effect is thus useless, as it is
smaller by a factor of 10^7.


Referring back to equation (I), consider a disc
of radius one kilometre. In this case a fringe
shift of one fringe is achieved with a velocity
at the perimeter of the disc of 0.013m/s. This
is an extremely low velocity, being less than
lm per minute. In this case the Sagnac effect
would be 50 billion times larger than the
calculated effect under the Relativity Theory.


Post (1967) shows that the two (Sagnac and STR) are of very different orders of magnitude. He says that the dilation factor to be applied under SR is “indistinguishable with presently available equipment” and “is still one order smaller than the Doppler correction, which occurs when observing fringe shifts” in the Sagnac tests. He also points out that the Doppler effect “is v/c times smaller than the effect one wants to observe." Here Post states that the effect forecast by SR, for the time dilation aboard a moving object, is far smaller than the effect to be observed in a Sagnac test.

Another fun part of trying to explain this effect away as partial aether drag is that as the shift is dependent upon the refractive index of the medium, and that varies with wavelength, you need different types of aether for each wavelength of light which is dragged differently by the medium.

This is seldom mentioned in discussions of the Sagnac effect, perhaps justifiably, because the "pure" Sagnac effect consists of the path dependence of the optical path length with respect to a rotating system, as distinct from the Fizeau effect of light propagating in a moving medium. Nevertheless, both of these effects are present in many real Sagnac devices."
Another fun part of trying to explain this effect away as partial aether drag is that as the shift is dependent upon the refractive index of the medium, and that varies with wavelength, you need different types of aether for each wavelength of light which is dragged differently by the medium.

ANOTHER VICTORY FOR FE!

You are done here.

For good.

You have just proven that you have no knowledge whatsoever about the SAGNAC EFFECT.

Sagnac effect in fiber gyroscopes

This is going to be groundhog day with a twist for you.
You mean you will just be repeating the same spam?
In that case I can just skip it.

I have shown you are blatantly lying about the papers you are using, and about what you are claiming I said/did.


After what happened to you yesterday, nobody here will ever care about anything you write, the fisking, the constant trolling, the desperate attempts to satisfy the cognitive dissonance.
You seem to be the last one to understand these very obvious things.
Like I have repeatedly told you, projecting will not help. You are describing yourself here, not me.

But this is the CORIOLIS EFFECT formula:
Like I said, if you want to play semantics, go ahead. If you want to pretend it is the Coriolis effect formula, go ahead. That will not change the fact that the shift expected for a rotating ring interferometer with normal mirrors is given by dt=4*A*w/c^2.

The SAGNAC EFFECT does not have an area incorporated into the formula.
Here is the proof:
https://web.infn.it/GINGER/administrator/components/com_jresearch/files/publications/sagnac_AJP.pdf
But it does. You even provided the proof.
Page 3 of the document. Page 428 of the journal. Equation 2 of the paper you are referencing.

What does it state the shift is?
THIS:
(https://i.imgur.com/IpaZbg7.png)
Notice how it states quite clearly that the shift is 4*A*w/c^2?

Your own reference agrees that the Sagnac effect for a rotating ring interferometer is a function of the area and angular velocity.
Stating that the Sagnac effect does not feature an area is a blatant lie, a lie which has been repeatedly pointed out to you which you have repeatedly ignored.

Now stop repeating the same lie and stop bringing up FOCs as they have no place in the discussion on a simple rotating ring interferometer.

THIS IS THE VERY SAME FORMULA DERIVED BY PROFESSOR YEH:
Stop lying.
Your formula is completely different from Yeh's.
Yeh's formula does not contain any linear velocity and again is for a different system.
Yeh's formula does not use the linear velocity of the fibre segments and your substitution amounts to nothing more than a blatant lie.

You repeating the same lie again and again won't help you.
Your lie has been exposed and there is no escaping it.

Professor Wang multiplies the radius by the angular velocity
For yet another different system.

Like I said, quit with the spam.

Start dealing with a rotating ring interferometer with normal mirrors.
Try finding a single reference which backs up your claims regarding what they shift should be for a rotating ring interferometer with normal mirrors.
You wont find any.
Do you know why?
Because you formula is pure nonsense with no connection to reality. Your derivation requires pretending a time difference and a total are the same thing, or that light will magically travel back in time.

The Sagnac effect is far larger than the effect forecast by relativity theory.
As has been explained to you plenty of times, it is a non-relativistic effect. You do not need relativity to invoke it.
But if you do a full relativistic derivation you end up with the same result.
This doesn't refute relativity at all. It just shows it isn't needed.

And it gets even worse for you, just like I promised.
PAGE 5
This experiment
As I told you before, it isn't an experiment.
It is a collection of previewed claims based upon assumed properties of a PCM which have not been demonstrated.
If it was actually valid it would have been published by now.
Wang likely had it rejected by journals and resorted to just posting it.

You have just proven that you have no knowledge whatsoever about the SAGNAC EFFECT.
https://www.osapublishing.org/ol/abstract.cfm?uri=ol-6-8-401
You mean you have proven you will just search for whatever you think ill support you and post it without any concern for what it actually indicates, just like all the other references you have posted which do not support you at all and instead refute you.
I wasn't discussing the Sagnac effect at all in my comment.

I have shown that I understand the Sagnac effect quite well, and that you have no idea what you are talking about, with you continually conflating/confusing FOCs with rotating ring interferometers and conflating normal mirrors with PCMs and having no idea how to derive the actual  shift.

I think this will be the last time in this thread I discuss any FOCs or PCMs until you deal with the simple rotating ring interferometer.


Like I said, if you want to actually try debating this is what you need to do:
Just focus on simple interferometer with normal mirrors and deal with the issues raised:
You need to refute my derivation which you have been unable to show any problem with.
You need to explain why you are finding the difference in time taken for a single beam of light, which corresponds to nothing in reality, and pretending it is the total time taken.
You need to explain why an interferometer which isn't rotating at all and instead is moving with uniform linear motion has a Sagnac shift, when symmetry demands it can't (and my formula says it can't, and the formula produced by so many people says it can't).

Until you have done that, you lose.
My derivation stands unchallenged and confirmed by a multitude of scientific references, including the references you use.
Your derivation stands defeated and unsupported by any scientific reference.
Your formula is refuted by a simple thought experiment.

You lose, big time.
Spamming again just means you lose even more.

No

The Sagnac effect is far larger than the effect forecast by relativity theory.

STR has no possible function in explaining the Sagnac effect.

The Sagnac effect is a non-relativistic effect.

COMPARISON OF THE SAGNAC EFFECT WITH SPECIAL RELATIVITY, starts on page 7, calculations/formulas on page 8

http://www.naturalphilosophy.org/pdf/ebooks/Kelly-TimeandtheSpeedofLight.pdf

page 8

Because many investigators claim that the
Sagnac effect is made explicable by using the
Theory of Special Relativity, a comparison of
that theory with the actual test results is given
below. It will be shown that the effects
calculated under these two theories are of very
different orders of magnitude, and that
therefore the Special Theory is of no value in
trying to explain the effect.

From the conclusion of the paper you cited. Apparently, it’s purely theoretical without any empirical evidence, unlike STR:

"8. Some experiments could be performed to test the conclusions of this paper.

Suggested experiments include:

1. A Michelson-Morley test on the moon, where there is no atmosphere. It would be interesting to determine whether the result is different from that on Earth.
2. A Sagnac test on the moon would show if the light travelled relative to fixed space, and ignored the movement of the moon.
3. Both of those tests repeated in space off a satellite or rocket.
4. A repeat of the Pegram tests would confirm the conclusion concerning electromagnetism"

Sagnac effect in fiber gyroscopes

H.J. Arditty and H.C. Lefevre

Optics Letters, vol. 6, 1981


The Arditty/Lefevre paper is a classic in the field, the best.

Only someone who has not studied this subject can state anything else.


Notice how it states quite clearly that the shift is 4*A*w/c^2?

The authors present TWO FORMULAS FOR THE SAGNAC EFFECT.

One has an area, the other one does not.

This is the entire point of the paper and of this discussion.

https://web.infn.it/GINGER/administrator/components/com_jresearch/files/publications/sagnac_AJP.pdf

The Sagnac effect and pure geometry

American Journal of Physics 83, 427 (2015)

Dr. A. Tartaglia and Dr. M.L. Ruggiero are two of the best known experts in ring laser interferometry and relativity in rotation frames in the world.


They present TWO FORMULAS for the Sagnac effect: amazingly and paradoxically these distinguished authors do not seem to infer the consequences of the two derivations.


The first formula, derived using differential geometry (page 3 of the pdf document), is this:

Δt = 4Aω/c2

A = area enclosed by the path of the light beams


Then, the authors derive A SECOND FORMULA for the Sagnac effect, which DOES NOT feature an area:

(https://image.ibb.co/cPs5vd/sagnac3.jpg)
(https://image.ibb.co/m86n8y/sagnac4.jpg)

This formula does not include the area at all, and is proportional to the VELOCITY of the light beams (and thus is proportional to the RADIUS of rotation).


Two different formulas, featuring two different physical descriptions.

This means that the formulas must be describing TWO DIFFERENT PHYSICAL PHENOMENA.


The first formula, which displays the AREA of the interferometer, is actually the CORIOLIS EFFECT formula:

https://www.ias.ac.in/article/fulltext/pram/087/05/0071

Spinning Earth and its Coriolis effect on the circuital light beams

The final formula is this:

dt = 4ωA/c2


CAN YOU READ ENGLISH?


(https://image.ibb.co/m86n8y/sagnac4.jpg)

NO ENCLOSED AREA APPEARS IN THIS EXPRESSION.


Your formula has AN AREA.

The SECOND FORMULA derived by the authors DOES NOT.


Here are your admissions that I am right:


But this is the CORIOLIS EFFECT formula:

It is saying what is known as the Sagnac effect is actually just the Coriolis effect.

If you want to call it the Coriolis effect instead, then go ahead, but the same arguments apply.



The "generalised Sagnac effect" for a FOC may be based upon a velocity


Your formula is completely different from Yeh's.


BUT IT IS THE VERY SAME!!!


Here is my formula:

2(V1L1 + V2L2)/c2

Let V1 = R1 x Ω

Let V2 = R2 x Ω

2(R1ΩL1 + R2ΩL2)/c2

=

2(R1L1 + R2L2)Ω/c2

THIS IS THE VERY SAME FORMULA DERIVED BY PROFESSOR YEH:

(https://image.ibb.co/mtGWny/mgrot6.jpg)

φ = -2(φ2 - φ1) = 4π(R1L1 + R2L2)Ω/λc

Since Δφ = 2πc/λ x Δt, Δt = 2(R1L1 + R2L2)Ω/c2

MY FORMULA!


It is one the same formula.

Had the MGX or the RLGs features a different situation, then the formulas obtaind would have been different.

Yet they are the very same.

This means that they describe the same situation.


Start dealing with a rotating ring interferometer with normal mirrors.

Of course.

For your information, PCMs act just like normal mirrors for the SAGNAC EFFECT.

(https://i.ibb.co/6Y9W45j/yeh5.jpg)

The MPPC acts like a normal mirror and Sagnac interferometry is obtained.


As I told you before, it isn't an experiment.

Professor Ruyong Wang is the greatest expert in the world on FOC and PCMs.

His papers are the most referenced when it comes to the linear/uniform/translational SAGNAC EFFECT, using FOC and PCMs.

Are you saying that his derivation is not correct?

Why don't you write to Professor Wang and let him know of your opinion?

Rest assured that his derivation is absolutely correct.


https://arxiv.org/ftp/physics/papers/0609/0609202.pdf

(https://image.ibb.co/g629jS/lis5.jpg)

The equation which expresses the relationship between interference fringes and time differences is F=dt[c/λ] (where dt = 4vL/c2).

This experiment shows us two important points. First, it confirms the phase reversal of a PCM and demonstrates the Sagnac effect in an arc segment AB, not a closed path. Second, it gives us important implications: The result, φ = 4πRΩL/cλ, can be re-written as φ = 4πvL/cλ where v is the speed of the moving arc segment AB (where R is the radius of the circular motion, Ω is the rotational rate).

If we increase the radius of the circular motion as shown in Fig. 6, the arc segment AB will approach a linear segment AB, the circular motion will approach the linear motion, the phase-conjugate Sagnac experiment will approach the phase-conjugate first-order experiment as shown in Fig. 4, and the phase shift is always φ = 4πvL/cλ.


The result, φ = 4πRΩL/cλ, can be re-written as φ = 4πvL/cλ


Professor Wang multiplies the radius by the angular velocity, AND NOT THE RADIUS BY THE LENGTH, like you have catastrophically just done.


https://arxiv.org/ftp/physics/papers/0609/0609202.pdf


PAGE 4

The phase-conjugate Sagnac experiment on a segment light path [16], not the closed path like that in the most Sagnac experiments, makes this argument even more
serious.

Here is reference [16]:

[16] P. Yeh, I. McMichael, M. Khoshnevisan, Appl. Opt. 25 (1986) 1029.

Professor Wang acknowledges that there IS NO CLOSED LOOP, NO AREA, in Professor Yeh's experiment.

(Although in the experiment [16], the flexible fiber path was rotating and the other optical parts were not, in a similar experiment [17] all optical parts were rotating together.) The result, φ = 4πRΩL/cλ, can be re-written as φ = 4πvL/cλ where v is the speed of the moving arc segment AB.

The greatest expert in the world on FOC and PCMs, Professor Ruyong Wang does not multiply the radius by the length, on the contrary.

He multiplies the angular velocity by the radius, JUST LIKE I HAVE DONE.


Moreover, he plainly states that the interferometer used by Professor Yeh DOES NOT INCLUDE AN AREA AT ALL, it is a segment light path.


Your trolling is not working anymore.

"(c) Jaseya et al [38] expriment. In this experiment two lasers were beating mounted on a rotating table; these lasers were arranged perpendicularly the one to other, (similarity with Michelson-Morley). It could really be very difficult to detect the from-East-to-West ether-drift -of velocity 0.35 km/sec at mean latitudes- on the Earth, This relatively small effect was much bellow the stability of lasers inside the magnetic field of the Earth."

By what means and how was it known to the author that the 'relatively small effect was much bellow the stability of lasers inside the magnetic field of the Earth’?

And, as an aside, why is this paper filled with spelling and grammatical errors? Was it ever peer reviewed by anyone or is is this just at the level of a blog? Doesn't seem like, "one of the best", if the very basics of communications are sloppy & flawed.

Edit: Upon further review, Antonis N. Agathangelidis, the author and book of his you referenced, "Relativity replaced – Ether found around Earth", you said as "One of the best".

Read the paper. You will learn plenty of things from it, aside from the ether vs relativity debate.

Since you are so stubborn, let me take care right now of your special relativity.

Yuri Galaev, Ph.D.; Senior research officer of the Institute for Radiophysics & Electronics National Academy of Sciences of Ukraine, and corresponding member of the Russian Academy of Natural Sciences (RANS)

The most significant development since Miller has been the
experiments of Yuri Galaev of the Institute of Radiophysics and
Electronics in the Ukraine. Galaev made independent measure-
ments of ether-drift using radiofrequency and optical wave
bands. His research not only "confirmed Miller's results down
to the details"but also allowed computation of the increase of
ether-drift with altitude above the Earth's surface (calculated to
be 8.6 m/sec per meter of altitude).

Now, the English translations of Dr. Yuri Galaev's groundbreaking work and most precise confirmation of the existence of dynamic ether (experiments carried out over the course of several years). Let us remember that, in what follows, it is the ether itself which flows above the flat surface of the earth and not the other way around... that is, both Miller and Galaev measured precisely the velocity and physical qualities of ether as it travels/propagates above the flat earth.

THE MEASURING OF ETHER-DRIFT VELOCITY AND KINEMATIC ETHER VISCOSITY WITHIN OPTICAL WAVES BAND Yu.M. Galaev The Institute of Radiophysics and Electronics of NSA in Ukraine


The positive results of three experiments [1-3], [7- 9], [10] give the basis to consider the effects detected in these experiments, as medium movement developments, responsible for electromagnetic waves propagation.

Such medium was called as the ether [11] at the times of Maxwell, Michelson and earlier. The conclusion was made in the works [1-3], that the measurement results within millimeter radio waves band can be considered as the experimental hypothesis confirmation of the material medium existence in nature such as the ether. Further discussions of the experiment results [1-3] have shown the expediency of additional experimental analysis of the ether drift problem in an optical wave band.


Thus, in the work, the hypothesis experimental verification about the ether existence in nature, i.e. material medium, responsible for electromagnetic waves propagation, in the optical wave band has been performed. The estimation of the ether kinematic viscosity value has been performed. The first order optical method for the ether drift velocity and the ether kinematic viscosity measuring has been proposed and realized.

The method action is based on the development regularities of viscous liquid or gas streams in the directing systems. The significant measurement results have been obtained statistically. The development of the ether drift required effects has been shown. The measured value of the ether kinematic viscosity on the value order has coincided with its calculated value.

The velocity of optical wave propagation depends on the radiation direction and increases with height growth above the Earth's surface. The velocity of optical wave propagation changes its value with a period per one stellar day. The detected effects can be explained by the following:
 
optical wave propagation medium available regarding to the Earth's movement;
 
optical wave propagation medium has the viscosity, i.e. the feature proper to material mediums composed of separate particles;

the medium stream of optical wave propagation has got a space (galactic) origin.

The work results comparison to the experiment results, executed earlier in order of the hypothesis verification about the existence of such material medium as the ether in nature, has been performed. The comparison results have shown the reproduced nature of the ether drift effect measurements in various experiments performed in different geographic requirements with different measurement methods application. The work results can be considered as experimental hypothesis confirmation about the ether existence in nature, i.e. material medium, responsible for electromagnetic waves propagation.

The following model statements are used at measuring method development [4-6]: the ether is a material medium, responsible for electromagnetic waves propagation; the ether has properties of viscous gas; the metals have major etherdynamic resistance. The imagination of the hydroaerodynamic (etherdynamic) effect existence is accepted as the initial position. The method of the first order based on known regularities of viscous gas movement in tubes [27-28] has been proposed and realized within the optical electromagnetic waves band in the work for measuring of the ether drift velocity and ether kinematic viscosity.

ETHERAL WIND IN EXPERIENCE OF MILLIMETRIC RADIOWAVES PROPAGATION Yu.M. Galaev The Institute of Radiophysics and Electronics of NSA in Ukraine


The ethereal wind speed value, measured in a radio frequency band at the work, is close to the ethereal wind speeds values, measured in electromagnetic waves optical range in the experiments of Miller [5, 6], Michelson, Peas, Pearson [11]. Such comparison results can be considered as mutual confirmation of the research results veracity, the experiment [5, 6] and the experiment [11].

The executed analysis has shown, that this work results can be explained by radiowaves propagation phenomenon in a space parentage driving medium with a gradiant layer speed in this medium ow near the Earth's surface. The gradiant layer available testifies that this medium has the viscosity -- the property intrinsic material media, i.e. media consisting of separate particles. Thus, the executed experiment results agree with the initial hypothesis positions about the Aether material medium existence in the nature.

I told you that you do not understand the Sagnac effect.
Yes, you have told me that repeatedly.
The problem is that you are yet to substantiate it in any way.
Instead you have repeatedly shown you either have no idea what you are talking about or your are intentionally lying to everyone.

My references are always the very best.
The main issue isn't your references, it is how you lie about and repeatedly claim that they back up your formula when they do no such thing.

The authors present TWO FORMULAS FOR THE SAGNAC EFFECT.
One has an area, the other one does not.
So you admit that you were blatantly lying when you falsely claimed that the Sagnac effect does not feature an area?
Especially when you were trying to use that paper, which has an area in the formula, to claim that the area isn't the formula?

Thanks for finally admitting that.

This is the entire point of the paper and of this discussion.
No. The entire point of this discussion is the Sagnac shift for a simple ring interferometer rotating about a point outside its centre.
The point of that paper was to extend the Saganc effect to a fundamentally different system, that of a fibre optic conveyor.

Then, the authors derive A SECOND FORMULA for the Sagnac effect, which DOES NOT feature an area:
Yes, almost as if there are 2 different ways to obtain this shift that is called a Sagnac shift.
One is for a rotating ring interferometer, one is for a fibre optic conveyor.
It isn't surprising that they derive 2 different formulas for 2 different things.

This formula does not include the area at all, and is proportional to the VELOCITY of the light beams (and thus is proportional to the RADIUS of rotation).
Stop lying.
There is no rotation for that formula and no rotation in that system.
That velocity is the velocity of the detector/source (referred to as the object) along the path of the fibre optic conveyor.
That formula has no bearing on a rotating ring interferometer.
It is for a FOC. Do you understand the difference?

Tell us, where in that image is the rotation?

Here are your admissions that I am right:
Again, STOP LYING!
That is my "admission" that the author of that paper is claiming that the Sagnac is the Coriolis effect.
No where in there do I admit that it is the Coriolis effect or that it is not the Sagnac effect.
THIS IS THE VERY SAME FORMULA DERIVED BY PROFESSOR YEH:
[/quote]
Again, stop lying.
Yeh's formula does not feature a linear velocity.
Instead, it uses the length of the fibre coil, the radius of the fibre coil, and the angular velocity of the rotation of the system.
This is equivalent to the area of the fibre coil (or more technically the number of loops multiplied by the area) and the angular velocity.
It is not equivalent to a linear velocity. If you want to use a linear velocity you need to find it for every section of the loop, as it changes.
The only way to make it equivalent to a linear velocity is to have both loops be concentric with the centre of rotation.

This means that they describe the same situation.
No, that doesn't.
The formula being the same does not mean it is the same situation.

Start dealing with a rotating ring interferometer with normal mirrors.
Of course.
For your information, PCMs
Stop lying.
If you are going to start discussing normal mirrors that means not discussing PCMs.

Professor Ruyong Wang is the greatest expert in the world on FOC and PCMs.
I don't care about your pathetic appeals to authority.

Why don't you write to Professor Wang and let him know of your opinion?
And why don't you write to the countless papers that have been provided by me and you which state quite clearly that the Sagnac effect for a rotating ring interferometer is based upon the Area of the interferometer, including those backed up by experimental results and tell them they are wrong and see what they say?

Or why don't you send your nonsense to Wang and see what he says?

Again, the references are on my side, not yours.


Now, quit with all the BS.
Stop bringing up PCMs and FOCs.
Deal with simple ring interferometers, and address the issues raised.

Like I said, if you want to actually try debating this is what you need to do:
Just focus on simple interferometer with normal mirrors and deal with the issues raised:
You need to refute my derivation which you have been unable to show any problem with.
You need to explain why you are finding the difference in time taken for a single beam of light, which corresponds to nothing in reality, and pretending it is the total time taken.
You need to explain why an interferometer which isn't rotating at all and instead is moving with uniform linear motion has a Sagnac shift, when symmetry demands it can't (and my formula says it can't, and the formula produced by so many people says it can't).

You have provided absolutely nothing to back up your claims.
You are yet to find a single reference which claims your formula is correct for a rotating ring interferometer, with normal mirrors.

All you have done is repeatedly avoided the issues and spammed mountains of garbage, blatantly lying about what papers contain.

Read the paper. You will learn plenty of things from it, aside from the ether vs relativity debate.

Since you are so stubborn, let me take care right now of your special relativity.

Is Antonis N. Agathangelidis one of the best you got?  You said as much. If so, I highly question the veracity of your arguments when they are based upon a self-published, zero reviews on Amazon, non-peer reviewed treatise filled with simple spelling errors. I think you can do better as this source you seem to champion is severely lacking from any and all scientific perspectives. Filled with assertions without any empiricism, just the ruminations of someone the scientific world pays zero attention to.

As evidenced by you not answered my one question, "By what means and how was it known to the author that the 'relatively small effect was much bellow the stability of lasers inside the magnetic field of the Earth’?"

Instead, you copy/pasta'd yet another foot of text, dancing away from my question. Is your intent to perpetually bury people in so much text, quotes, formulae so as to hide the fact that you can't answer a simple question?
Title: Re: On Sandokhan definitions of the Sagnac and Coriolis Effects
Post by: sandokhan on October 02, 2019, 02:36:24 AM
That is my "admission" that the author of that paper is claiming that the Sagnac is the Coriolis effect.
No where in there do I admit that it is the Coriolis effect or that it is not the Sagnac effect.


But you did admit that it is the CORIOLIS EFFECT.

This is as far as we need to take this "debate".


But this is the CORIOLIS EFFECT formula:

It is saying what is known as the Sagnac effect is actually just the Coriolis effect.

If you want to call it the Coriolis effect instead, then go ahead, but the same arguments apply.



YOU HAVE JUST ADMITTED THAT YOUR FORMULA IS ACTUALLY THE CORIOLIS EFFECT FORMULA.


You cannot change your mind just a day later.

Don't you understand what kind of an image you have built for yourself on this very forum?

Once you have admitted that the formula which does feature an area is the Coriolis effect, you can't go back on your statement.


There is nothing else to debate here.


So you admit that you were blatantly lying when you falsely claimed that the Sagnac effect does not feature an area?

The authors are preseting TWO FORMULAS FOR THE SAME EFFECT, they refer to this effect as the SAGNAC EFFECT.

The entire point of this discussion is the Sagnac shift for a simple ring interferometer rotating about a point outside its centre.
The point of that paper was to extend the Saganc effect to a fundamentally different system, that of a fibre optic conveyor.


See how easy it is to spot your utter ignorance on the subject of the Sagnac effect?

The FOC will measure the SAGNAC EFFECT in a uniform/translational/linear motion.

A SEGMENT LIGHT PATH.

Exactly as that featured by Professor Yeh or by a ring laser gyroscope.


Your readers are simply laughing at your cognitive dissonance.


Yes, almost as if there are 2 different ways to obtain this shift that is called a Sagnac shift.
One is for a rotating ring interferometer, one is for a fibre optic conveyor.
It isn't surprising that they derive 2 different formulas for 2 different things.


It is the very same interferometer, the very same principle.

Go ahead and write to your nearest university and let them know that you think otherwise.


Here in the real world, we have the very same interferometer.


However, now we have two different formulas.


One features an area, the other one does not.


CAN YOU READ ENGLISH?

(https://image.ibb.co/m86n8y/sagnac4.jpg)

NO ENCLOSED AREA APPEARS IN THIS EXPRESSION.


Your formula has AN AREA.

The SECOND FORMULA derived by the authors DOES NOT.


There is no rotation for that formula and no rotation in that system.
That velocity is the velocity of the detector/source (referred to as the object) along the path of the fibre optic conveyor.
That formula has no bearing on a rotating ring interferometer.
It is for a FOC. Do you understand the difference?


There is no difference whatsoever: both can measure the SAGNAC EFFECT.

If you now rotate the SEGMENT LIGHT PATH INTERFEROMETER, AS IN THE MGX OR RLGs, WHAT HAPPENS?

Exactly as Professor Yeh did.

Exactly as Michelson assumed it would happen.


You are talking nonsense again.

You are trolling this forum.


Your references SUFFER from the same defect exhibited by virtually all of the papers published since 1913.

Now, using PCMs, physicists are beginning to realize that there TWO FORMULAS TO DEAL WITH.

Your reference ONLY DEALS WITH THE FORMULA WHICH HAS AN AREA.

It does not touch the other formula.


The formula being the same does not mean it is the same situation.

So you realize that THE FORMULAS ARE THE VERY SAME.

It is the same situation: both measure the SAGNAC EFFECT.

This is equivalent to the area of the fibre coil (or more technically the number of loops multiplied by the area) and the angular velocity.
It is not equivalent to a linear velocity.


Here is PROFESSOR RUYONG WANT TELLING YOU THAT YOU ARE WRONG.

There is no area!

https://arxiv.org/ftp/physics/papers/0609/0609202.pdf

(https://image.ibb.co/g629jS/lis5.jpg)

The equation which expresses the relationship between interference fringes and time differences is F=dt[c/λ] (where dt = 4vL/c2).

This experiment shows us two important points. First, it confirms the phase reversal of a PCM and demonstrates the Sagnac effect in an arc segment AB, not a closed path. Second, it gives us important implications: The result, φ = 4πRΩL/cλ, can be re-written as φ = 4πvL/cλ where v is the speed of the moving arc segment AB (where R is the radius of the circular motion, Ω is the rotational rate).

If we increase the radius of the circular motion as shown in Fig. 6, the arc segment AB will approach a linear segment AB, the circular motion will approach the linear motion, the phase-conjugate Sagnac experiment will approach the phase-conjugate first-order experiment as shown in Fig. 4, and the phase shift is always φ = 4πvL/cλ.


The result, φ = 4πRΩL/cλ, can be re-written as φ = 4πvL/cλ


Professor Wang multiplies the radius by the angular velocity, AND NOT THE RADIUS BY THE LENGTH, like you have catastrophically just done.


https://arxiv.org/ftp/physics/papers/0609/0609202.pdf


PAGE 4

The phase-conjugate Sagnac experiment on a segment light path [16], not the closed path like that in the most Sagnac experiments, makes this argument even more
serious.

Here is reference [16]:

[16] P. Yeh, I. McMichael, M. Khoshnevisan, Appl. Opt. 25 (1986) 1029.

EXACTLY MY REFERENCE!!!

Professor Wang acknowledges that there IS NO CLOSED LOOP, NO AREA, in Professor Yeh's experiment.


The phase-conjugate Sagnac experiment on a segment light path [16], not the closed path like that in the most Sagnac experiments, makes this argument even more serious.


And it gets even worse for you, just like I promised.

PAGE 5

This experiment shows us two important points. First, it confirms the phase reversal of a PCM and demonstrates the Sagnac effect in an arc segment AB, not a closed path. Second, it gives us important implications as analyzed below. (Although in the experiment [16], the flexible fiber path was rotating and the other optical parts were not, in a similar experiment [17] all optical parts were rotating together.) The result, φ = 4πRΩL/cλ, can be re-written as φ = 4πvL/cλ where v is the speed of the moving arc segment AB.

Here are references [16] and [17]:

[16] P. Yeh, I. McMichael, M. Khoshnevisan, Appl. Opt. 25 (1986) 1029.
[17] I. McMichael, P. Yeh, Opt. Lett. 11 (1986) 686.

First, it confirms the phase reversal of a PCM and demonstrates the Sagnac effect in an arc segment AB, not a closed path.


The result, φ = 4πRΩL/cλ, can be re-written as φ = 4πvL/cλ


Professor Wang multiplies the radius by the angular velocity, AND NOT THE RADIUS BY THE LENGTH, like you have catastrophically just done.


The greatest expert in the world on FOC and PCMs, Professor Ruyong Wang does not multiply the radius by the length, on the contrary.

He multiplies the angular velocity by the radius, JUST LIKE I HAVE DONE.


Moreover, he plainly states that the interferometer used by Professor Yeh DOES NOT INCLUDE AN AREA AT ALL, it is a segment light path.



Now, I am going to use the 14pt font, perhaps you'll understand better.


Here is my formula:

2(V1L1 + V2L2)/c2

Let V1 = R1 x Ω

Let V2 = R2 x Ω

2(R1ΩL1 + R2ΩL2)/c2

=

2(R1L1 + R2L2)Ω/c2

THIS IS THE VERY SAME FORMULA DERIVED BY PROFESSOR YEH:

φ = -2(φ2 - φ1) = 4π(R1L1 + R2L2)Ω/λc

Since Δφ = 2πc/λ x Δt, Δt = 2(R1L1 + R2L2)Ω/c2


MY FORMULA!


It is one the same formula.

Lets start with this:
To find a total time from 2 times, t1, and t2, do you:
a) Add the 2 times together so the total time is t1+t2, or
b) Subtract one time from the other to find the difference in the time, such that the total time is t1-t2 (or potentially t2-t1, who knows).

No, I complained about the paper you referenced from some one as "One of the best" in your words. Come to find out, he's a hack. So a hack is 'one of your best'. Which calls into question a lot of things.

I then ask you a direct question about one of your statements regarding your 'one of the best' and you deliberately sidestep it and move on to yet another foot of copy/pasta that is not relevant to the specific question at hand.

So you may ask your dear readers, why do you not address simple questions with simple answers? But instead perpetually overload a response with a foot of quotes, links, etc., with never addressing the direct, simple question at hand. This is why over at scienceforums.net the mods ultimately shut you down with:

"Moderator Note
Since the OP appears impervious to reason and genuine scientific rebuttal, this thread is closed."


Not because they were flummoxed by your overwhelming scientific prowess, but because they were frustrated by your overwhelming lack of self awareness. Literally only 2 people ever engage on a topic with you because of it. The tedium of obfuscation is the overwhelming on your part.

Simply answer a direct, simple question with a direct, simple answer instead of with a foot of the same copy/pasta, over, and over again:

By what means and how was it known to the author that the 'relatively small effect was much bellow the stability of lasers inside the magnetic field of the Earth’?

And there's no trolling here. I'm just trying to get you to actually address a question rather than slather a bunch of other people's work all over the place to avoid it.

That paper of yours claims that this is not actually the Sagnac effect and instead is just the Coriolis effect. It is not saying that the Sagnac effect is something different. It is saying what is known as the Sagnac effect is actually just the Coriolis effect.

If you want to call it the Coriolis effect instead, then go ahead, but the same arguments apply. Your formula is still wrong. The formula for the actual shift observed will remain as 4*A*w/c^2.

You are exhibiting intellectual dishonesty.
Again, projecting will not save you.

Here is what you said yesterday, in full view:
It is saying
Again, do you understand English?
That is not me admitting that it is, that is me saying that that article is saying something.

As an easier example, if I say:
"you are saying Earth is flat"
that is not me admitting Earth is flat. That is simply me stating that you say Earth is flat. It is "admitting" that you say Earth is flat.

This is not a difficult concept to grasp.

The same applies to your claims about Stash. He wasn't saying Toronto was under water, he was saying that if was flat, Toronto would need to be under water, as the water level in the photo is in line with the Toronto skyline, so either the water curves down before reaching Toronto (i.e. Earth is round) or Toronto is under water.

Again, that is not a difficult concept to grasp, but you completely misrepresent it.

It would be like me taking this quote of yours:
here is what you did:
Now instead of adding and subtracting based upon direction, we will add the terms of the same colour, corresponding to the one beam rotating around the interferometer and then find the difference.
dt=l1/(c - v1)+l2/(c + v2)-l1/(c + v1)-l2/(c - v2)
=l1/(c - v1)-l1/(c + v1)+l2/(c + v2)-l2/(c - v2)
=l1(c + v1-c + v1)/(c2 - v12)+l2(c - v2-c - v2)/(c2 - v22)
=2*l1v1/(c2 - v12)-2*l2v2/(c2 - v22)
Where you attack the formula I derive, and claim that that is you admitting that the formula for the Sagnac effect is given by:
dt = 2*l1v1/(c2 - v12)-2*l2v2/(c2 - v2

You really make me wonder what your problem is. Do you just seriously not understand English and thus don't understand what is being said and what the papers are saying? Do you understand English but not understand the science involved and thus say what you think, which ends up being completely wrong?
Or do you understand it all and know what you are saying is wrong?

See how easy it is to defeat you?

Just take a look at the trolling perpetrated by your friends, whom you are defending.

Imagine if YOU had a formula, beautifully derived, which coincides exactly with the formula published in the Journal of Optics Letters by one of the top physicists in the world.

And someone else would make trolling requests and avoid to acknowledge that the formula is actually correct.

No other forum would alllow jackblack's despicable trolling as it is allowed right here.

I understand you are very proud of your formula and that's great. Sometimes it's difficult to convince other people even if you are 100% right, in those cases approaching the problem from a different angle might help. Sometimes you are 100% sure you are right, but in the end it turns out you were wrong, happens to everyone.

Let me ask you this: Has any known physicist ever agreed that your derivation is correct? Or someone with a PhD in Physics?

And please don't answer the paper agrees with you, I mean a real person telling you the derivation is correct.

Yes.

Dr. P. Yeh
PhD, Caltech, Nonlinear Optics
Principal Scientist of the Optics Department at Rockwell International Science Center
Professor, UCSB
"Engineer of the Year," at Rockwell Science Center
Leonardo da Vinci Award in 1985
Fellow of the Optical Society of America, the Institute of Electrical and Electronics Engineers

He derives a SAGNAC EFFECT formula for an interferometer which has two unequal sides (thus, resulting in two velocities for the light beams as well).

Here is the final formula:

(https://i.ibb.co/MsS5Bb5/yeh4.jpg)

φ = -2(φ2 - φ1) = 4π(R1L1 + R2L2)Ω/λc = 4π(V1L1 + V2L2)/λc

Since Δφ = 2πc/λ x Δt, Δt = 2(R1L1 + R2L2)Ω/c2

It coincides exactly with my formula.

Which means I am right.

Post by: sandokhan on October 02, 2019, 09:02:02 AM
Now here a summary of this thread, which might also be interpreted as a grand finale.

This is the CORIOLIS EFFECT formula:

dt = 4ωA/c^2

Proof:

https://www.ias.ac.in/article/fulltext/pram/087/05/0071

Spinning Earth and its Coriolis effect on the circuital light beams

The final formula is this:

dt = 4ωA/c^2


Even the chief troller of this website agrees:


But this is the CORIOLIS EFFECT formula:

It is saying what is known as the Sagnac effect is actually just the Coriolis effect.

If you want to call it the Coriolis effect instead, then go ahead, but the same arguments apply.




If that is the CORIOLIS EFFECT formula, what then is the actual SAGNAC EFFECT formula?

Here is a clue:

https://web.infn.it/GINGER/administrator/components/com_jresearch/files/publications/sagnac_AJP.pdf

The Sagnac effect and pure geometry

American Journal of Physics 83, 427 (2015)

(https://image.ibb.co/cPs5vd/sagnac3.jpg)
(https://image.ibb.co/m86n8y/sagnac4.jpg)

NO ENCLOSED AREA APPEARS IN THIS EXPRESSION.


So, the SAGNAC EFFECT formula applies TO A SEGMENT LIGHT PATH, not the area at all.


SAGNAC EFFECT WITHOUT AN AREA OR A LOOP

https://arxiv.org/ftp/physics/papers/0609/0609202.pdf

(https://image.ibb.co/g629jS/lis5.jpg)

This experiment shows us two important points. First, it confirms the phase reversal of a PCM and demonstrates the Sagnac effect in an arc segment AB, not a closed path. Second, it gives us important implications: The result, φ = 4πRΩL/cλ, can be re-written as φ = 4πvL/cλ where v is the speed of the moving arc segment AB (where R is the radius of the circular motion, Ω is the rotational rate).

If we increase the radius of the circular motion as shown in Fig. 6, the arc segment AB will approach a linear segment AB, the circular motion will approach the linear motion, the phase-conjugate Sagnac experiment will approach the phase-conjugate first-order experiment as shown in Fig. 4, and the phase shift is always φ = 4πvL/cλ.


Then, the most important question: what is the SAGNAC EFFECT for the Michelson-Gale experiment?

Here is the correct derivation:

https://www.theflatearthsociety.org/forum/index.php?topic=30499.msg2117351#msg2117351


By far, the most important formula in physics today: it can answer each and every major question ever posed by science.


Here it is in all its beauty:

2(V1L1 + V2L2)/c2

Let V1 = R1 x Ω

Let V2 = R2 x Ω

2(R1ΩL1 + R2ΩL2)/c2

=

2(R1L1 + R2L2)Ω/c2

Here is the final ingredient: STOKES' THEOREM.

This alone PROVES that there are TWO FORMULAS for the interferometer: one is proportional to the AREA, the other one is proportional to the velocity.


According to Stokes' rule an integration of angular velocity Ω over an area A is substituted by an integration of tangential component of translational velocity v along the closed line of length L limiting the given area. This interpretation gives

Δt = 4vL/c2

producing the same value as the earlier expression for the interferometer. This can also be demonstrated by geometrical relations. These two integrations have different physical implications. We must therefore decide which one is correct from a physical aspect. Mathematics can not tell us that. So the decision is whether the effect is caused by a rotating area or by a translating line. Since Sagnac effect is an effect in light that is enclosed inside an optical fiber we can conclude that Sagnac effect is distributed along a line and not over an area. No light and no rotation exists in the enclosed area. Sagnac detected therefore an effect of translation although he had to rotate the equipment to produce the effect inside the fiber.

We conclude that the later expression

Δt = 4vL/c2

is the correct interpretation.

http://www.gsjournal.net/Science-Journals/Research%20Papers-Astrophysics/Download/2159

"Sagnac effect is distributed along a line and not over a surface. The assumption that starts from an integration over a surface (2Aw; rotation) is mathematically correct (due to Stokes' rule) but equal to a line integral (vL; translation). We must decide if the reason is a translating line or a rotating surface from a physical point of view. The rotation theory is correct only mathematically. Since the effect is locked inside an optical fiber the translating line is the correct interpretation. Classification as a rotational effect is wrong."

Professor Ruyong Wang has proven the Sagnac effect applies to uniform/translational/linear motion:

https://arxiv.org/ftp/physics/papers/0609/0609222.pdf

https://arxiv.org/ftp/physics/papers/0609/0609202.pdf

http://web.stcloudstate.edu/ruwang/ION58PROCEEDINGS.pdf


For each interferometer there will ALWAYS be two formulas: one is proportional to the area (CORIOLIS EFFECT), the other one is proportional to the velocity (SAGNAC EFFECT).


Here is another reference which clearly spells this out:

https://shodhganga.inflibnet.ac.in/bitstream/10603/137225/7/07_chapter_02.pdf

Chapter 2.8 (page 44 of the paper, page 25 of the pdf document)

One should note that though the area enclosed by light contour is zero, the Sagnac phase shift is still non-zero and the length of the light contour determines the Sagnac phase shift formula.

Sagnac phase shift depends on the lengths and speed of the moving fibre and these are the fundamental factors, rather than the enclosed area determining the SD, as customarily quoted (say, in Ref. [12])- because they observed Sagnac effect even when their FOC has zero-area.

The LSE (thought) and FOC (laboratory) experiment prove beyond doubt that Sagnac formula has nothing to do with the area enclosed by the light contour.


Therefore, here we have the final proof that there are ALWAYS two formulas to be derived for an interferometer: one formula features the area, the other one is proportional to the length of the path and the velocity of the light beams.

You still don't get it.

My formula was derived INDEPENDENTLY of the paper published by Professor Yeh.

The first time EVER where the SAGNAC EFFECT formula for the MGX has been derived.

The derivation is FLAWLESS.

Go ahead and read it.

The proof lies in the final formula: it is precisely identical to the one derived by Professor Yeh, no need to call anyone.


Now, you also have STOKES' THEOREM, my previous message, which PROVES beyond a shadow of a doubt, that the are ALWAYS TWO FORMULAS for each and every interferometer.


The paper on the CORIOLIS EFFECT was published in one of the most respected scientific journals in India, see the SPRINGER-VERLAG publisher page.

You claim you have a very important formula or derivation. The most important in modern physics. "It can answer each and every major question ever posed by science".  Yet all you do is post in the FES forums and discuss your formula with Rabinoz and Jackblack, who btw are the only people who care about looking at your important formula. You should probably thank them for doing that instead of trying to get rid of them.

It sounds pretty ridiculous to be honest. If you are in possession of such an important scientific breakthrough, why hide it here at the FES forums where barely anyone can see it?

As long ago as 1938, one of the top physicists in the world, Dr. Herbert Ives (Bell Telephone Laboratories) proved that the SAGNAC EFFECT is linear:

Ives analyzed the Sagnac experiment using a hexagonal path rather than a circular one.

In 1938 Ives showed by analysis that the measured Sagnac effect would be unchanged if the Sagnac phase detector were moved along a cord of a hexagon-shaped light path rather than rotating the entire structure. Thus, he showed the effect could be induced without rotation or acceleration."

It seems that your client (since you are acting here as his lawyer) does not. Both of you are trolling this forum.
No, everyone here knows what your formula is.

It is not the same as Yeh's no matter how many times you want to lie and say it is.
Even if it was, it doesn't matter, as it is a fundamentally different system.

I have answered each and every question possible: no one else would show such courtesy on any other forum.
Stop lying. You have repeatedly avoided the questions. This is consistently your behaviour.
You make a false claim, it gets refuted, I ask simple questions to show the problem, and you run from them.

See how easy it is to utterly defeat you?
Again, you have defeated no one.
But we all see how easy it is to completely defeat you.
All it takes is a single simple question which you are unable to answer because you know answering it will show you are lying or have no idea what you are talking about.

In order for you to start defeating people, you need to start addressing the issues raised. As you haven't, all your claims remain refuted.

The derivation is FLAWLESS.
Except for the massive flaw you are repeatedly ignoring and refusing to answer a very simple question on.
This flaw is where you pretend a time difference is the total time.

So I ask again:
To find a total time from 2 times, t1, and t2, do you:
a) Add the 2 times together so the total time is t1+t2, or
b) Subtract one time from the other to find the difference in the time, such that the total time is t1-t2 (or potentially t2-t1, who knows).

Which one do you think it is?

Either tell everyone here that you think to find a total time you find the difference between the times, or admit you doing so in your derivation is wrong.

Until you have answered this question you will have defeated no one.

You tried to claim that Toronto was under water.

You took that as far as you could, while claiming all the while that you are "concerned".

Just like you are doing now.

Your gig is over.

You can only do this ONCE, now you've blown your cover already.

Actually, I never claimed it was 'underwater'. You simply could never could explain why the skyline was obscured by 10's of meters of water. That should never happen on a flat earth. But that's another topic.

If you don't like Dr. Agathangelidis' paper, there is nothing else I can do for you on the subject.

I then demolished your STR hypothesis using the GALAEV ether drift experiments.

Very easy.

Hardly demolished, just simply sidestepped. And your sidestepping is painfully apparent to your readers. You won't even answer a simple question about the paper you cited as "one of the best". Instead, you copy/pasta the same formula over and over again. Like doing so makes a difference. That is called 'spam'.

And because you can't defend the Dr. Agathangelidis' paper question, you sidestep once again to GALAEV. Everyone can see what you're doing. It's not a mystery to anyone.

The folks over at the scienceforums will say anything to fool their readers, the fact that you play along says quite a lot.

They had no answers to provide once I clearly showed them that there were two formulas for the SAGNAC EFFECT.

The had plenty of answers and plenty of comments. Anyone can look up the fact that you did the same thing over there: Just continued to copy/pasta the same thing over and over again to the point where they had to shut down your OP. That's why they responded with:

"Moderator Note
Since the OP appears impervious to reason and genuine scientific rebuttal, this thread is closed."

Seems to be a pattern with you which you seemingly can't make yourself aware of.

So why don't you retrench, remove a modicum of over-exaggerated ego and answer my question and JackBlack's question rather than just copy/pasta'ing the same thing over and over again. Be direct and address, not sidestep and obfuscate.

And this proof can be extended to MGX interferometer or for a ring laser gyroscope.


Also for a circular coil with N turns, one DOES NOT multiply N by the area (there is no "area", just a segment light path), but one multiplies N by L and the total product is multiplied again by V.

Proofs forthcoming.

No where near as simple as you make it.
You can't just stick in any velocity. You need to use the appropriate integral.

But again, thanks for admitting the Sagnac effects features an area, and thus all the times you said it didn't were lies.

You, jackblack, have been reported for SPAMMING.

Your question was answered a long time ago:
It is yet to be answered in this thread.
Even in the mountain of spam you link to, it still isn't answered.

This is a very simple question which exposes the massive flaw in your derivation, yet you refuse to address it.

Again, this is a very simple question. If you were correct you would have no problem addressing it.
The only reason to not address it is that you know it exposes you.

It is the key difference between your derivation and mine.
For my derivation, I find the total time by adding together the 2 times.
For your derivation, you subtract one time from the other, what most people would call a difference, not a total.

So answer quite clearly for everyone here, do you think you find a total by adding the values up or by finding the difference between them?

You derived the CORIOLIS EFFECT formula.

This is the CORIOLIS EFFECT formula:

dt = 4ωA/c^2

Proof:

Spinning Earth and its Coriolis effect on the circuital light beams

The final formula is this:

dt = 4ωA/c^2


Even you, the chief troller of this website, agree:


But this is the CORIOLIS EFFECT formula:

It is saying what is known as the Sagnac effect is actually just the Coriolis effect.

If you want to call it the Coriolis effect instead, then go ahead, but the same arguments apply.

In the thread you reference above you state:

THIS IS THE CORIOLIS EFFECT FORMULA.

Here is the precise proof, peer-reviewed in an IOP article.

THIS IS AN IOP ARTICLE, one of the most comprehensive papers on the Sagnac effect ever published.

(https://image.ibb.co/eqXahp/sil4.jpg)

(https://image.ibb.co/bX3aXp/sil2.jpg)


Here is reference #27:

(https://image.ibb.co/eCKok9/sil3.jpg)

I checked out that paper, "The Sagnac effect: correct and incorrect explanations" you reference. (I could only find the Russian version so had to Google translate portions of it.) In the abstract, the author, G.B. Malykin, states:

"Various explanations of the causes of the Sagnac effect are considered. It is shown that the effect Sagnac is a consequence of the relativistic law of velocity addition. This effect also finds an adequate explanation in the framework of the general theory of relativity...It is also shown that all nonrelativistic explanations of the Sagnac effect which, unfortunately, are found in a number of scientific articles, monographs and training courses, are fundamentally wrong, although in a number of special cases they lead to the correct one up to relativistic corrections result."

From his Conclusion:

"As was shown above, the Sagnac effect is a consequence of the relativistic law of addition of velocities - the speed of propagation of an arbitrary wave the nature and speed of rotation of the interferometer a - and, therefore is a kinematic effect With T About [10, 11]. It was also shown that in the absence of gravitating masses, i.e. in the absence of curvature space, calculating the Sagnac effect from a point The view of ST O and O O is completely equivalent."

Point being, he goes over many varied explanations of the causes of the Sagnac effect and determines that it "is a consequence of the relativistic law of addition of velocities." Which I believe is contrary to your position. You just happened to pull out the part in his paper where he is going over Silbestein's particular explanation among the other explanations he examined in the paper.

You regard this paper as "one of the most comprehensive papers on the Sagnac effect ever published." My question is, do you agree with Malykin's premise that "all nonrelativistic explanations of the Sagnac effect...are fundamentally wrong"? And his conlusion that, "the Sagnac effect is a consequence of the relativistic law of addition of velocities."?

Post by: sandokhan on October 03, 2019, 01:48:14 PM
You haven't done your homework.

G. Malykin's treatise has over 300 references, and yet, it missed one of the most important ones, a paper published by Dr. Silberstein in 1922.

In 1922, Dr. Silberstein published a second paper on the subject, where he generalizes the nature of the rays arriving from the collimator:

http://gsjournal.net/Science-Journals/Historical%20Papers-Mechanics%20/%20Electrodynamics/Download/2645

This paper explains the issue raised by Malykin, but evidently missed by him.

Why is this SO IMPORTANT?

From Malykin's paper, section 5.5, Sagnac Effect and Coriolis Forces

The author of Ref. [27] thought that the effect of Coriolis forces
on counterpropagating waves in a three-mirror ring interferometer
accounted for the optical path of a wave travelling
in the direction of rotation in the form of a triangle with
somewhat convex sides; a wave spreading in the opposite
direction had an optical path in the form of a triangle with
somewhat concave sides. For this reason, the triangles had
different areas. Hence, the relative time delay between the
counterpropagating waves, the additional travel time of each
wave dependent on the Sagnac effect being proportional to
the closed contour area [35].
After a little while, however, A Lunn [70] showed that the
triangles are actually equal in area even though their contours
for counterpropagating waves are not quite coincident during
rotation (the contribution of the deflection of each counterpropagating
light beam caused by the Coriolis forces to a
change of the contour area is totally compensated for by the
contribution from the altered angle of incidence on the next
mirror). It is easiest to demonstrate the equality of contour
areas for counterpropagating waves in a fixed frame of
reference where Coriolis forces are lacking. In such a case,
only rotations of reflecting mirrors at given moments need to
be taken into consideration as was done by M Laue [69].


However, Dr. Silberstein answered Lunn's paper in 1922, and showed that Lunn's explanation was incomplete.

Malykin MISSED this most important reference.

But not me.

Had Malykin read the 1922 reference, he could not have dismissed Silberstein's papers.

Question: did Malykin actually know of the 1922 publication by Silberstein, but chose not to include it on his list of references?

So it has been answered already, hasn't it?
No, it hasn't.

The closest you have come to answering it is providing your derivation, but that avoids the issue rather than providing a nice simple direct answer.

So provide a nice simple direct answer.

Stop with your spam and stop with your lies.
Just answer the question:
To find a total time from 2 times, t1, and t2, do you:
a) Add the 2 times together so the total time is t1+t2, or
b) Subtract one time from the other to find the difference in the time, such that the total time is t1-t2 (or potentially t2-t1, who knows)?

Which one do you think it is?


This is the crux of our disagreement.

With my derivation, I find the total time for the clockwise path by adding the time taken in each of the arms. I do the same for the counter clockwise path by adding the time it takes in each of the arms.
I then find the Sagnac shift by finding the difference of those 2 times, as that is what the Sagnac shift is, the time difference (or phase difference which is directly related) between the 2 counter-propagating beams of light.

Doing this, along with the assumption of an annular interferometer (required for the simple formulas used to determine the shift, and required to be able to ignore the other 2 arms) results in the correct formula of dt=4Aw/c^2.
That is the correct derivation.

In order for it to not be correct and instead have your derivation be correct you would need to assert that I found the total time using a wrong method.
What you did was find the "total time" for the clockwise beam by finding the difference in time taken to traverse each arm.
This makes no sense and does not connect to reality at all.

If you truly believe this is the correct way to find the total time I want you to admit to everyone here that you think to find a total time you find the difference between the 2 times.

If you do not agree with that and are unwilling to admit that then the only other option is that your derivation is fundamentally wrong.

So which is it? Do you think that to find a total time you find a time difference, or is your derivation wrong?

If you don't want to do that, then how about providing a graph showing the position of a photon of light as it travels along the path as a function of time? You can ignore arm 2 and arm 4, have the left side of arm 1 be y=0, the right side be y=l1, coincident with the right side of arm 3, and then the left side of arm 3 being y=l1+l2.

So can you produce such a graph, from which the difference in time (i.e. Sagnac shift) can be directly taken from the graph?

I'll produce one and post it here shortly.

You are wasting your time.
Yes, it does seem that you have no interest in addressing the issue and trying to have a debate.

Going to more complex systems is pointless when we can't even deal with a simple case.

You derived the CORIOLIS EFFECT formula.
Like I said before, if you want to call it that, go ahead, that doesn't mean it isn't the Sagnac formula nor that it doesn't describe the actual shift.

You wanting to change its name does nothing.

Now can you address the massive flaw in your derivation?

So far all there is to say my derivation is wrong is your baseless claim and assertion that your derivation is correct.

Can you admit that either your derivation is wrong, or admit that you think to find a total time you add together 2 times?

Also, as I said, here is a graph:
This shows the progression of the beam of light around the loop, and has the time difference at the end quite clear:
https://www.desmos.com/calculator/2xsazmjcrc
(https://i.imgur.com/jP8wPQG.png)
This uses the formulas provided before, with the final time difference also matching the formula I have provided before.

i.e. the first section of the red line takes a time of l1/(c-v1). The second section takes l2/(c+v2).
This gives a total time of l1/(c-v1) + l2/(c+v2).
For the green line you instead have l2/(c-v2) and l1/(c+v1), giving a total time of l2/(c-v2) + l1/(c+v1).
This gives a time difference of l2/(c-v2) + l1/(c+v1) - (l1/(c-v1) + l2/(c+v2)), clearly indicated at the end.

This is the real time difference between the arrival of the 2 beams and thus is the shift that is observed.

This again, shows my formula is correct.

Meanwhile, your formula requires that the red path ends before it even reaches the end of the first arm, physically impossible.

Now, can you produce one for your derivation, showing how the difference in time arises, or finally admit your derivation is wrong?

I read Silberstein's 1922 open letter (not a 'paper') regarding Lunn's criticism. I'm not seeing any direct refutation, as Malykin states, that "all nonrelativistic explanations of the Sagnac effect...are fundamentally wrong." And his conclusion that, "the Sagnac effect is a consequence of the relativistic law of addition of velocities."

Did I miss something in Silberstein's 1922 letter? If so, what might that be?
Title: Re: On Sandokhan definitions of the Sagnac and Coriolis Effects
Post by: sandokhan on October 03, 2019, 09:38:30 PM
The 1922 paper was not meant to be a refutation of something relating to relativity, but of Lunn's previous criticism.

Dr. Silberstein showed that the effect measured by Sagnac, using his non-symmetrical interferometer was actually caused by THE CORIOLIS EFFECT.

Therefore, Malykin missed this most important fact: Silberstein's 1921 paper could not be dismissed.

jackblack, your ramblings are meaningless and they have ALREADY BEEN ADDRESSED RIGHT HERE:

https://www.theflatearthsociety.org/forum/index.php?topic=82968.msg2203590#msg2203590

PAGE 1 OF THIS VERY THREAD


Here is STOKES' THEOREM applied to the light interferometer:

(https://i.ibb.co/yY9K7FQ/stokes3.jpg)

You derived the formula for the LEFT SIDE OF THE EQUATION.

I derived the formula for the RIGHT SIDE OF THE EQUATION.

Are you able to understand this very simple thing?

Now, for the MGX/RLGs, there will also be a factor of proportionality: R/L.

R x (https://i.ibb.co/yY9K7FQ/stokes3.jpg)  x L

This factor of proportionality was proven, for the first time, for the LISA Space Antenna:

Again, please try and understand.

You derived the CORIOLIS EFFECT formula, the left hand side of Stokes' line integral applied to the light interferometer.

I derived the SAGNAC EFFECT formula, the right hand side.

Your formula is proportional to the area of the interferometer.

My formula is proportional to the velocity of the light beams.

Unless you can understand this very fact, there is nothing else anyone here can do for you.


Like I said before, if you want to call it that, go ahead, that doesn't mean it isn't the Sagnac formula nor that it doesn't describe the actual shift.

But it is the CORIOLIS EFFECT.

Which is COMPLETELY DIFFERENT than the SAGNAC EFFECT.

It can't be the SAGNAC EFFECT.

The CORIOLIS EFFECT is a physical effect on the light beams, a slight modification of their path.

The SAGNAC EFFECT is an electromagnetic effect, the modification of the velocities of the light beams.

They cannot be the same.

You seem to be very confused.

You are running circles within your own mind, unable to acknowledge the reality: you derived the CORIOLIS EFFECT, while I derived the SAGNAC EFFECT.

My formula is completely validated by Professor's Yeh own derivation, published in the Journal of Optics Letters.

Yet, you will not understand these very basic facts, and are continuing to SPAM and TROLL this forum.
