I can see the earth rotating and hear it breathing.

Its funny, most reactions come from de US and Canada. I made the video with the people in mind who are not able to visit Paris each day. But if you can, go. In the basement they still keep de funeral wreaths of some guy's of 1789.

It's amazing that this thing is actual proof of the earth rotation.

I imagined it to move slower, actually.

some sweet info here

Beautiful, I want to go there :)

It is, indeed, an amazing thing to watch.

@born2die636 sorry i meant 24hr/sin latitude for anyplace else

[tampicokeed]

@born2die636 due to earths rotation, there is a "coriolis effect" (simply put it is the earth turning under anything in motion) In north hemi (where the earth moves fr W to E--counterclockwise) , a thing in motion turns RIGHT (not left), In case of pendulum in each motion (swing) it veers a small amount to RIGHT. Cannon shell fired lands farther to RIGHT the more north you go. Obviously the pend makes 1 whole turn (CLOCKWISE) in 24hrs on N POLE, and 24 hr/cos of latitude anyplane else.

You know, I sleep. But since I've seen this movie, I sleep well again ;)

@j1836 {It's amazing that this thing is actual proof of the earth rotation.}

More significantly, it proves, to put it dramatically -- "there is a hook, a constant point, the center of the universe, on which everything else hangs -- the unmoved and unmovable"

See, it measures not only the earths rotation, but every movement we make relative to this fixed space. The universal coordinate.

@j1836

How long it takes for the pendulum to move, no matter the weight of the pendulum or hard the pendulum is pushed, is determined by the length of the string or in this case cable. Essentially, if you quadruple the string length, the time it takes for the pendulum to swing doubles. The exact equation: T = 2(pi) sqrt(L/g) where T = time(seconds), sqrt is square route, L = length of cable(in meters), and g = force of gravity(on earth that is 9.8 meters/second^2)

when does it stop? Never ends? Nice power source ^^
