Ever since Albert Einstein's General Theory of Relativity burst upon the world in 1915, some of the world's most brilliant minds have sought to decipher the mysteries bequeathed by that legacy. Einstein himself was resistant to its implications, but physicists, astronomers and cosmologists have argued over his theory ever since. This volume is a history of Einstein's ideas as they made their way through the increasingly political world of science. Kip Thorne is the co-author (with John Wheeler and Charles Misner) of Gravitation.
