Kip Thorne: Einstein's General Relativity, from 1905 to 2005 11/16/2005 [56k modem] [broadband] [cable/DSL] 73 minutes In an Einstein lecture, Kip Thorne, Feyman Professor of Theoretical Physics at Caltech, discussed the theory of general relativity, which Einstein announced 90 years ago in November 1915. Since then, physicists have struggled to understand and test its predictions. This struggle has led to theories about black holes, gravitational waves, and the acceleration of the universe; and at Caltech/JPL, to powerful tools for probing warped spacetime.
