Lecture 21: The Rotation and Revolution of the Earth
How do we prove physically that the Earth rotates on its axis and\nrevolves around the Sun? Newtonian physics was so compelling that it\nwas mostly accepted before there were ironclad physical demonstrations\nof the Earth's daily rotation about its axis and annual revolution\n(orbit) around the Sun. This lecture reviews three of these\ndemonstrations: the Coriolis Effect, the Foucault Pendulum, and Stellar\nParallaxes. This ties up the last loose-end of the Copernican\nRevolution. Recorded 2006 Oct 19 in 100 Stillman Hall on the Columbus\ncampus of The Ohio State University.
