The Theory of Everything is a unique opportunity to explore the cosmos with the greatest mind since Einstein. Based on a series of lectures given at Cambridge University, Professor Hawking s work introduced "the history of ideas about the universe" as well as today s most important scientific theories about time, space, and the cosmos in a clear, easy-to-understand way. Professor Hawking transformed our view of the universe in his landmark bestselling book A Brief History of Time, and most recently in the bestselling Universe in a Nutshell. Here he reviews ideas about the universe from Aristotle to Newton and Einstein, applying the principle of quantum mechanics to the Big Bang, black holes, and the universe s ultimate fate. He goes on to advance a "no boundary" theory of time and space that could lead to one unified theory and a true understanding of our universe. The Theory of Everything presents the most complex theories, both past and present, of physics; yet it remains clear and accessible. It will enlighten readers and expose them to the rich history of scientific thought and the complexities of the universe in which we live.
