Is The Earth A Flat Round Disc or Is It a Round Spherical Globe?

1851 Paris Observatory 'proof of rotation'

The pendulum's swing rotated clockwise 11° per hour, making a full circle in 32.7 hours.

South Pole Foucault Pendulum – Winter, 2001

Principal Investigators: Mike Town, Ph.D. candidate, University of Washington; John Bird, Ph.D., FBIS, P.Eng, York University; R. Allan Baker, Sonoma State University

A Foucault Pendulum at the South Pole was determined to have a period of 24 hours, ± 50 minutes.

"Standing on the bottom of the world the Earth spins backward relative to the direction it spins in the Northern Hemisphere. Our first attempt with the pendulum showed the Earth spinning backward from what was expected. We didn't notice this at first because we're all from the Northern Hemisphere and are accustomed to the earth spinning in an anticlockwise direction. We then realized that from our frame of reference the earth should be spinning clockwise so we had to modify the pendulum. At an altitude of 11,000+ feet we think a bit more slowly.

The air resistance against this weight caused the pendulum itself to rotate. This gave us spurious results for our first attempt. Later we fashioned the weight so that it was hanging horizontally to the plane of the floor and we got results consistent with what was expected. Our second attempt showed the earth rotating in the proper direction but at an angular velocity twice what is expected (i.e., 12 hour days instead of 24). Our last attempt showed that the earth spins on its axis once every 24 hours, as expected.

It was difficult to make the pendulum swing in a plane instead of an ellipse. After several attempts with various techniques of holding the bob and dropping it we always got some kind of ellipse instead of a plane. This adds to our error because it is more difficult to locate and mark the pendulum arc's apex."

If not, then we have a perpetual motion machine!  What's being used to maintain it's oscillations?  Explanations of the mechanics (snapshot below).

has i have said months ago it is not PM but easy to move with your hand

this not a proof = this is inconclusive experiment

in paris the penduleum works as expected

No, It didn't work as expected in the 1851 Paris observatory 'rotation' experiment.  The experiment is promoted and tailored to show what they need it to show. The explanation they give us disproves itself.

An animated explanation of "Airy's Failure" experiment

An experiment known as "Airey's Failure" involves filling a telescope with water to slow down the speed of light inside. Usually telescopes must be slightly tilted to get the starlight down the axis of the tube supposedly due to "Earth's speed around the sun." Airey discovered that actually the starlight was already coming in at the correct angle so no change was necessary. This demonstrated that the stars move relative to a stationary Earth and not the other way around; if it was the telescope moving, he would have to change the angle.
