Einstein's Universe

Einstein's Universe is a 1979 BBC documentary hosted by Peter Ustinov, which is based on the book Einstein's Universe by Nigel Calder. In this film Ustinov becomes educated in Einstein's theories by many of the best minds in science, who provide demonstrations to illustrate his teachings. These include experiments to help understand gravity, warped space, how light responds to gravity, the "Doppler effect" and how radio waves, as used in police radar, are an unbeatable way of measuring speed. From these simpler experiments much larger concepts are drawn, such as the discovery of a Binary Pulsar, the nature of black holes and how they are created, and the ultimate theory of how the universe was formed. Other demonstrations measure the speed of light, how time passes more slowly for people traveling in an airplane, the incredible accuracy of the Atomic Clock in Washington, DC and how time itself would appear to stop at the surface of a black hole.
