The area loop around the equator (a vector) is parallel to the axis of rotation - the axis of earth's rotation so this dot product is maximised.

But for a loop flat on the surface at the equator, its area is normal to the axis of rotation so the dot product is zero.


Once you mention the word AREA you are dealing with the CORIOLIS EFFECT.

Not with the SAGNAC EFFECT.

Moreover you quoted from Neil Ashby who clearly stated these facts.

In a rare admission, even N. Ashby states that the Coriolis force is responsible for the term commonly used in GPS technology for the Sagnac effect:

Your derivation leads to this formula:

dt = 4ωA/c^2

This is the CORIOLIS EFFECT formula.

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.


Don't even bother bringing up studies/papers which utilise phase conjugate mirrors as that has no relevance to a interferometer without them.

Please update your knowledge on the subject.

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

It is saying the Sagnac effect can be explained as the Coriolis effect, i.e. they are the same


They cannot be the same.

Here is the formula derived by Dr. Silberstein, clearly described as being explained by the Coriolis force:

dt = 4ωA/c^2



Here is my formula:

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

[irrelevant nonsense removed]

Again, can you show any problem with my derivation?
Can you provide a valid citation for a rotating ring interferometer with normal mirrors which agrees with you, not me?
Can you provide your own derivation, starting from the basics of a stationary loop?
Can you explain why you are claiming that a square interferometer moving uniformly (i.e. all of it moving together with no rotation) will record a shift?

Asserting I am deriving the wrong formula, when that is the subject of debate, is basically just the same as asserting you are right. IT DOES NOTHING TO HELP YOUR CASE.
Bringing up phase conjugate mirrors does not help your case.

Once you mention the word AREA you are dealing with the CORIOLIS EFFECT.
Incorrect! Every expression for the Sagnac effect has the loop area either explicitly or implicitly.

I asked YOU to explain why your Sagnac equation gives a delay when flat on the surface of the equator - you have no done so!

Everyone except you gives the Sagnac delay as proportional to the area of the loop and don't try claiming "Phase-conjugate fiber-optic gyro by Pochi Yeh et al".
Even Pochi Yeh's "Phase-conjugate fiber-optic gyroPhase-conjugate fiber-optic gyro", .

And here's the frequency shift for a large ring laser gyroscope:
, where:
A = enclosed area,
P = perimeter (beam path length),
λ = optical wavelength,
n = normal vector to A and
Ω = rotation vector.

There is no area whatsoever involved in the SAGNAC EFFECT formula.

Ever.

The area comes up ONLY in the CORIOLIS EFFECT formula.

Please update your knowledge on the topological considerations of the Sagnac effect:

https://www.theflatearthsociety.org/forum/index.php?topic=30499.msg2023979#msg2023979

The SAGNAC EFFECT is a comparison of two loops, no area comes up at all in the derivation.

The CORIOLIS EFFECT is a comparison of two sides, the area always comes up in the derivation.

A huge difference.

Everyone except you gives the Sagnac delay as proportional to the area of the loop and don't try claiming "Phase-conjugate fiber-optic gyro by Pochi Yeh et al".
Even Pochi Yeh's "Phase-conjugate fiber-optic gyroPhase-conjugate fiber-optic gyro", .


Professor Yeh's SAGNAC LOOP has no area at all.

It is the SAGNAC EFFECT without an area.



NO AREA, just TWO LOOPS.

So, you have just lied, again, to your readers, because you are really desperate.

This is the CORIOLIS EFFECT frequency formula:



It does include the AREA.

This is the SAGNAC EFFECT frequency formula:

Δf = Δφ x c/P = [4L(v1 + v2)]/λP

No area at all, JUST THE VELOCITIES.

For the GINGERino RLG at Gran Sasso, Italy, the SAGNAC EFFECT FREQUENCY is 2,616,666.666 times greater than the Coriolis effect frequency:

Yeah, I don't get the point behind the massive walls of formula when the poster won't engage in simple questions like "What is the axis of aether rotation at different latitudes" and "Would a mechanical flywheel gyro and a laser ring gyro give the same rotational readings if in the same position and orientation on the earth."

Is there a complete disconnect between theory and the real world?

I for one would love to know if Bob Knodel's gyro gave the highest angular rate reading when aligned  with its sensitive axis to Polaris.

Your derivation leads to this formula:

This is the CORIOLIS EFFECT formula.
Yes, the correct formula which is more commonly known as the Sagnac effect formula, as they are one in the same.
Repeatedly showing that I have gotten the correct formula will not help your case.

You have been completely unable to show a single problem with my formula. Instead all you have been able to do is repeatedly show it is the correct formula.
Just like you have been completely unable to show the Sagnac effect and the Coriolis effect on a counterpropagating light beams is different.

My derivation does use loops. You have seen that every time.
So you lying and saying it doesn't doesn't help your case.
If anyone's doesn't use loops it would be yours as you aren't bothering to determine the time taken to go around the loop and instead are just looking at 2 arms and finding the difference there, and then adding differences up.

So if you want to complain about not using loops, you are complaining about your own derivation.

Now either show what is wrong with my formula, provide a valid citation discussing the Sagnac effect which uses only a simple ring interferometer with normal mirrors with the entire apparatus rotating, or show your own derivation starting from the basics of how long it takes light to propagate around a stationary loop.
If you are unwilling or unable to do that then go away as you are clearly not interested in debate and just want to preach.

Can you provide your own derivation starting from the basics of how long it takes light to propagate around a stationary loop?
Can you provide a paper which shows the Sagnac effect for a simple ring interferometer with the entire setup rotating (so no PCMs or the like and no FOCs or the like) have a formula other than what I have (or equivalent to it)?

Until you do, every post you make is just trolling and spamming and wasting everyone's time.

Phase-Conjugate Multimode Fiber Gyro

Published in the Journal of Optics Letters, vol. 12, page 1023, 1987

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

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.

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




Here is a step by step explanation of how your formula does not make use of LOOPS, which are required in the SAGNAC EFFECT:

And yet again:

https://www.theflatearthsociety.org/forum/index.php?topic=79637.msg2148569#msg2148569


Your derivation leads to this formula:

dt = 4ωA/c^2

This is the CORIOLIS EFFECT formula.

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 the derivation of my formula, which is being used by the US NAVAL RESEARCH OFFICE, using two LOOPS, as required by the correct definition of the SAGNAC EFFECT:

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.

BK's RLG registered a 15 degree per hour drift.

The RE on youtube are mocking his experiment, saying all the while "I told you so".

Albert Michelson was the first physicist to claim that the formula used in detecting rotation, dt = 4ωA/c^2, is the SAGNAC EFFECT formula.

However, this is the CORIOLIS EFFECT formula, here is a very easy derivation:

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

The derivation has NO LOOPS at all.

The definition of the SAGNAC EFFECT involves TWO LOOPS.

No loops, no SAGNAC EFFECT.

The error committed by Michelson is a fundamental one: he used the Coriolis effect formula to describe a very different phenomenon, the SAGNAC EFFECT.

Here is the derivation of my formula, which is being used by the US NAVAL RESEARCH OFFICE, using two LOOPS, as required by the correct definition of the SAGNAC EFFECT:

The US NAVAL RESEARCH OFFICE, Physics Division, is using my formula.
Stop lying.
They are using a different formula, for a completely different setup.

That setup is irrelevant to the discussion at hand as it uses a PCM.

Laser ring gyroscopes, like that used by Bob Knodel which proved the Earth rotates (as do all experiments like this) did not use a PCM.

You have brought up the Sagnac effect and your wild claims about it in countless threads.
You have been refuted in every one of them in that I have seen which allowed debate.
You have refused to engage in any form of rational discussion on the subject and instead just repeatedly assert the same refuted nonsense and dismiss anything that goes against it, even from your own sources.

You are clearly unwilling to debate the Sagnac effect and instead just want to preach.
If you want to preach, do it in the preaching forum, not this one.

And like I have said repeatedly, if you want to appeal to authority, then you've already lost, as all the authorities you are appealing to accept Earth is round and rotating.

The phase-conjugate mirror ACTS AS A NORMAL MIRROR.

Please read.



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

You are unable to read and comprehend a very simple known scientific fact: the PCM acts as a NORMAL MIRROR.


When faced with the truth, you are accusing someone else of lying, instead of realizing that by now the readers of this thread and of your messages are beginning to realize that you are unable to face reality.


PLEASE READ AGAIN:


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


The set-up is exactly the same.


That is why I included the exact quotes from the scientific papers, so that you will have no excuse at all in denying this fact.

That's his words and the words of others of the Globebusters YouTube site.

Quote from: sandokhan

The most vicious attacks come from other flat earthers, especially his own Globebusters group. Take a look at:

Bob Knodel of Globebusters is a LIAR and a SATANIST and getting THE BOOT by Awake Souls

Well, it looks like you are the someone! No flat earther would take any notice of me on YouTube ::). I'm not exactly flavour-of-month ::).

By the way, do you know who wrote this, "Standard fiber-optic gyros are Sagnac interferometers that are inherently insensitive to reciprocal phase changes and sensitive to nonreciprocal phase changes"?

BK registered the Coriolis effect of the ether drift. This is a basic fact which all RE and FE on youtube must understand.

By the way, do you know who wrote this, "Standard fiber-optic gyros are Sagnac interferometers that are inherently insensitive to reciprocal phase changes and sensitive to nonreciprocal phase changes"?

Is this supposed to be a joke on your part?

You mean you don't know the difference between reciprocal phase changes and nonreciprocal phase changes?

ROTATION (SAGNAC EFFECT) is a nonreciprocal phase change, which produces a net phase shift.

A nonreciprocal phase shift, in an interferometer, is due to the Sagnac effect ( the phase shift produced by the Sagnac effect is nonreciprocal).

[more garbage preaching]
Like I said, if all you want to do is preach, do it in the believers only section.

If you want to try debating the Sagnac effect, go back to any of the countless threads where you have your ass repeatedly handed to you and discuss it there.

So far all your claims have been refuted and you have been completely unable to show any error from others, and you can't even manage an extremely simple derivation.

This means that the Sagnac effect remains proportional to the area and angular velocity, and that means Bob measured the rotation of the Earth.

SAGNAC EFFECT WITHOUT AN AREA



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.

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)


NO AREA INVOLVED IN THIS SAGNAC EXPERIMENT.


Here is a SECOND experiment performed by Professor Yeh, a SAGNAC EXPERIMENT WITHOUT AN AREA:




Phase-conjugate fiber-optic gyro, P. Yeh, I. McMichael, M. Khoshnevisan, Applied Optics 25(7):1029-30 April 1986

http://www.dtic.mil/dtic/tr/fulltext/u2/a170203.pdf (appendix 5.4)

FINAL FORMULA:

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


ONLY the CORIOLIS EFFECT formula involves an area:

4Aω/c2



Well, it looks like you are the someone! No flat earther would take any notice of me on YouTube

My comments on two different youtube videos, relating to the BK experiment, were deleted within half an hour.

So, if someone here wants to contact BK, or even awakesouls, that would be great.
