The Pole Star lies exactly overhead if seen from the North Pole. The farther south you travel, the lower it gets in the sky. It's not visible from the Southern Hemisphere at all, due to bulge in the middle portion of Earth. As Hawking notes, in Ancient Greece this was one of the proofs cited for the curvature of Earth.

Hold a basketball over your head and notice how you can't see things on top or directly above it if your looking up from the bottom.
