Few figures loom as large as Albert Einstein in our contemporary culture. It is remarkable that a man from such humble beginnings—an unemployed dreamer who was written off by his professors as a hopeless failure—could dare to scale such heights. In this enlightening book, Michio Kaku reassesses Einstein's work by centering on his three great contributions: special relativity, general relativity, and the unified field theory. Einstein first formulated the equation E = mc², which has become a fixture of our culture. His subsequent theories led to the Big Bang theory and have changed irrevocably the way we perceive time and space. Michio Kaku offers a fresh look at Einstein's pioneering work, giving a clearer portrayal of his enduring legacy than previous biographies. As today's physicists continue their search to fulfill Einstein's most cherished dream—the "theory of everything"—Einstein is recognized as a prophet who set the agenda for modern physics.
