Title: Radius of the Earth proves spherical
Post by: mightyfletch on March 08, 2007, 04:57:39 PM
The surface distance from the North Pole to the Equator is 10,011.720km.  For this point, we're only going to use the Northern Hemisphere.

The circumference at the equator is 40,075.02km.

Using the formula 2*Pi*r=Circumference however, the circumference on a flat Earth would be 62,905.492km

FE Equatorial circumference=62,905.49km (38,087.66 miles) while the actual measured circumference is 40,075.02km (24,901.46),
a difference of   22830.47km  (14186.20 miles).

Therefore the Flat Earth is proven impossible.

Here, I'll simplify it and show you step by step.

What's 2 times Pi?     About 6.28

what's 6.28 times 10,012?

about 62,900.  That would be the equatorial circumference of a flat Earth.

The true equatorial circumference is 40,075 km.

NO, but the radius can be found by using a stopwatch.

Once you find the radius you can know all the attributes of the Earth.

My stopwatch doesn't have that function, and if it did I wouldn't trust it . . . because WTF?

No, I didn't read your link, sorry.

Now that I have read the article, it makes many assumptions about the shape and movement of the Earth.  Can you see what these assumptions are?

The observation can still be made on a disk. It all depends on when the Sun appears and disappears.  The Flat Earth model has a sunset and sunrise.  That's all that's needed.

I don't mean to go off on a tangent or anything, but has anyone accounted for the acceleration towards the edge of the rotating Flat Earth which would cause sea-levels to be consistently and significantly greater as you move south? 

Not to mention the fact that a mere 150ft ice wall could not withstand the immense water pressure of such event.

If anyone even tries to say that the Earth doen't rotate, I will quickly put them in their place with atmospheric mechanics.

But with different assumptions we must make different conclusions based on the observation.  Assuming a flat Earth this observation would be a measure of the curvature of light (according to EricTheRed's thread on light-curvature). 

In either case, though, nothing about the shape or size (or anything) is proved because of the assumptions made.

True,  since your height is added to the distance from the center of the Earth(spherical radius). So you would already have to assume the Earth is a sphere in order to get the radius with this experiment.

Everyone on this forum when given this issue has said just that. 

Coriolis Effect can only occur on a rotating body.  Coriolis effect is the reason for Buys Ballot's Law that when you stand with your back against the wind lower pressure is to your left in the Northern hemisphere.  Also, Vorticity is stronger towards the poles since the Coriolis effect is much stronger.  Also, the Subtropical jet is formed as Coriolis force causes it to recurve back to the Equator inducing the conservation of angular momentum thereby producing higher winds. 

The Coriolis force would be much much stronger on a flat disk than on a sphere.  Not to mention the fact that cyclonic rotation in the southern hemisphere is in opposite direction from that of the Northern hemisphere  which would be impossible on a flat Earth.

Would you like me to elaborate?

The Coriolis effect is caused by the container that holds the atmosphere on the flat earth.  The flat earth does not rotate.

So much for your knowledge of atmospheric mechanics.

Please describe the arcane properties that your mystical container posesses that allow it to spin rising parcels of air counter-clockwise and sinking parcels of air clockwise.

The atmosphere is not the only thing that reacts to the coriolis force.  If you fill a large flat circular container with about an inch of water and a small hole in the center, allowing it a couple of weeks to stop moving, and drain the water, you will see the coriolis effect manifested.   

Also, the ocean currents are formed by the Coriolis force.  Only they go clockwise in the Northern hemisphere and counter-clockwise in the Southern Hemisphere.

It is quite an excercise to come up with good defenses.  Before this forum I did not know you could measure the Earth's radius
with a stopwatch.  I had to look that one up.  As for the weather stuff, I use this knowledge everyday to forecast for the Air Force.  I guess that means I must be a part of the force behind the government cover up.

I think a good argument to debunk the curved horizon would be the whole bending light theory that explains the sun rises and sunsets.

Alright, if it is then why does it get hotter at the equator(also, if you're a FEer then you should think that the equator is a nickname for the circumference of the ROUND DISC YOU CALL EARTH)? The answer for REers is that the sun hits there more and so it's hotter. YET ANOTHER STRANGE CONCEPT, THE SUN MAKES THINGS HOT.

The Earth is not a "round disc," and no serious FEer would say that. You have bought the pseudo-FE conspiracy hook, line and sinker.

I agree that the Sun makes certain regions hotter at different times. That has nothing to do with your nonsense about imaginary circumference or hemispheres.

I never said that Coriolis significantly affects the direction of a toilet.  What I'm saying is that the rotation of airmasses is entirely dependent on Coriolis.  Low pressure systems rotate counter-clockwise, and high pressre systems rotate clockwise in the northern hemisphere.  Opposite in the Southern Hemisphere.

Since these hemispheres are wholly imaginary, there must be another reason for it. I am not familiar with weather systems, but someone with more education in the topic would be able to point you to the correct science I'm sure.

Post by: mightyfletch on March 09, 2007, 11:28:16 PM
I'll explain the nitty gritty of how it works.  For example, in the Northern hemisphere when hot air rises it induces lower pressure at a location.  This causes air from the surrounding area to move in.  As the parcels move, Coriolis deflects them to the right (or the Earth beneath the air moves) and they begin to flow counteclockwise around the low and begin to rise.  Areas of high pressure are falling so they go the opposite direction (clockwise).

The reason Coriolis occurs can be illustrated even on a disk.  A sphere is not neccessary.  Start at any point on the circle and face East.  Go in a straight line and you will find yourself going closer to the edge of the disk (equator or in the most popular FE, the Ice Wall).  In order to keep going East you have to always be correcting yourself to the left/north.  On a sphere the change is much more gradual.  Try it on a globe.  Since the force is so much stronger on a disk, computer weather models and meteorology would be completely ineffective and no meteorologist would ever be the slightest bit close to a correct forecast since all weather forecasts are based on a spherical Earth.

Right. They show the wind direction and speed.  Every so often I forecast for a different military installation in the South central thogh South East U.S.    A satellite was just sent up that is supposed to be able to work kind of like a very big RADAR.  I don't know too much about though.  With every new advance in computers, forecasting becmoes more accurate.  Satellite imagery was one of the best improvements ever made allowing us to watch the progression of systems that before we could only draw on paper using weather baloon data.  It is so complex that computers have to be the main force if we ever hope to have the "Back to the Future II" precision.  These computers all have Coriolis as a parameter.  My forecasts deal in aviation weather.  So I not only ave to tell you that it's going to be cloudy, but tell you that 5/8 of the sky will have clouds at 12000 feet and so forth.

Also, to improve precision we must have more measurements across the U.S.  It's similar to sample rate in a sound file.  The more samples you have, the less you have to extrapolate and the more subtleties you can pick up on.

I am a professional Air Force Weather Forecaster with a Degree in Meteorology.  Television forecasters don't deviate from the weather models which is why my forecasts are better than theirs.   My forecasts are tailored to aviation which has higher tolerances than civilian forecasts.  Television forecasters are more focused on radio broadcasting than meteorology.  Even the most with Meteorology degrees only learn the physics behind meteorology and don't actually learn how to forecast the weather.

Frankly, I find this FE thing more than a little disturbing, but I'll respect that you have an alternative opinion. However...

Who said the Earth was a circle?
If that is an FE belief, then where does this http://i11.tinypic.com/2w2mzr5.png (http://i11.tinypic.com/2w2mzr5.png) come from?
It's used for explanatory purposes by one of your own, Tom Bishop.

Let's subsume your position so far. You believe in an imaginary Equator, imaginary hemispheres, and you think reality is 2D. Anything non-trollish in all of this nonsense?

Uhh...Yeah, another bit of confusion. As Eviloothpaste said, it's imaginary as in "not visible;" it's simply used as a guideline on sections of Earth. Also, where do you come up with this "2D reality" idea? Reality is clearly believed to be 3D. Otherwise, why would 3D graphics be designed with the goal of trying to produce more real and lifelike imagery?

I don't believe the Earth has a shape. I believe that the surface of the Earth is an infinite plane.
Again, refer to the link above. Also, can you explain how people have circumnavigated Earth by your theory?

And why are you so incessantly rude? It's really unnecessary.

ok simplifying it down cause you have a fraction over a fraction we get w=(u+v)*c^2/(1+(u*v)) assuming we let something fall from stop for one second at and acceleration of 9.81m/s^2 it will go from 0m/s to 9.81m/s.  by your formulea w=((0+9.81)*3*10^8/)1+0=2943000000m/s........ a slight anomoly

You guys were using 9.81m/s/s, I missed the part where he took of the acceleration part to just make 9.8m/s.  SO it looked like you were using it for acceleration.   But either way there is no reason to use that formula at such slow speeds.  It will be accurate just adding them together.

There is no way you are in college.  If you are, you must be no further than basic algebra.

Look:

w = (u + v) / (1 + u*v/ c^2)

Let's take this slowly.

u = 0.  This is our current velocity, and we are starting at rest.
v = 9.8m/s.  This is our additional velocity, due to accelerating at 9.8 m/s^2 for 1 second.

Now, (u + v) = (0 + 9.8 ) = 9.8.

(1 + u*v/c^2) = (1 + 0*9.8/c^2) = (1 + 0) = 1.

Therefore, w = 9.8/1 = 9.8.
