The year 2005 marks the 100th anniversary of the publication of the paper that launched Einstein's career, made E=mc2 famous, and ushered in a revolution in science--the paper that announced the theory of special relativity. And there's no better short book that explains just what Einstein did than Einstein's Cosmos. Keying Einstein's crucial discoveries to the simple mental images that inspired them, Michio Kaku finds a revealing new way to discuss these ideas, and delivers an appealing and always accessible introduction to Einstein's work.
