Default What if (On Foucault's Pendulum

Pendulums tell us a lot O ya. This French guy was clever.He proved the
earth was actually rotating about its own axis. Hmmm Setting up a
pendulum at the North Pole makes the pendulum movement entirely
independent of the Earth's and planetsimply rotates under it.(Tricky
stuff) An observer on the poles would see the plane of the pendulum's
motion turn clockwise through 360 degrees once every 24 hours Here
you see the pendulum rate depends on latitude. Going into the southern
hemisphere it even changes direction and goes "anticlockwise"
Imperial minds explain the motion of a pendulum as a psudo-force,
"known as aCoriolis force acting here." Go figure Bert PS Boston
museum has a Foucault pendulum. I watched it for many hours. Bert
