  • I saw a Foucault pendulum in a physics research lab. It was quite fascinating.
    I don’t think the rising and setting of sun is convincing evidence for rotation of the earth as the geocentric frame of reference is valid as Dr Greene explained.
    I think convincing direct evidences of spinning of the earth are
    1. Coriolis effect (it’s effect can be observed in hurricanes, tornadoes and air and sea currents)
    2. The way in which distant celestial objects move in the night sky. Polaris in the north pole and Sigma Octantis in the south pole don’t move and as you move away from them the radius of stars’ apparent circular path increases till the equatorial plane and then decreases to zero at the other pole.
