A dazzling tour of the universe as Einstein saw it. How did Albert Einstein come up with the theories that changed the way we look at the world? By thinking in pictures. Michio Kaku leading theoretical physicist (a cofounder of string theory) and best-selling science storyteller shows how Einstein used seemingly simple images to lead a revolution in science. Daydreaming about racing a beam of light led to the special theory of relativity and the equation E = mc2. Thinking about a man falling led to the general theory of relativity giving us black holes and the Big Bang. Einstein's failure to come up with a theory that would unify relativity and quantum mechanics stemmed from his lacking an apt image. Even in failure, however, Einstein's late insights have led to new avenues of research as well as to the revitalization of the quest for a "Theory of Everything." With originality and expertise, Kaku uncovers the surprising beauty that lies at the heart of Einstein's cosmos.
