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 |
