In fact my criticism of the book is that it presumes considerable knowledge by the reader and some of the theories seem farfetched.

Nevertheless this book is a challenge and I cannot honestly say that I grasped all of it. Like many of the other reviewers I have a technical background in engineering and have read widely in the area of physics and quantum theory. The illustrations are excellent and contribute to your understanding of what is being discussed but even so the concepts are not simple to grasp. This is not a book for the timid or for those who have not read other and simpler books on quantum theory. Copious four-color illustrations help clarify this journey into a surreal wonderland where particles, sheets, and strings move in eleven dimensions where black holes evaporate and disappear, taking their secret with them and where the original cosmic seed from which our own universe sprang was a tiny nut. With characteristic exuberance, Professor Hawking invites us to be fellow travelers on this extraordinary voyage through space-time. And he lets us behind the scenes of one of his most exciting intellectual adventures as he seeks “to combine Einstein’s General Theory of Relativity and Richard Feynman’s idea of multiple histories into one complete unified theory that will describe everything that happens in the universe.” He takes us to the wild frontiers of science, where superstring theory and p-branes may hold the final clue to the puzzle. In his accessible and often playful style, he guides us on his search to uncover the secrets of the universe - from supergravity to supersymmetry, from quantum theory to M-theory, from holography to duality.

Like many in the community of theoretical physicists, Professor Hawking is seeking to uncover the grail of science - the elusive Theory of Everything that lies at the heart of the cosmos. In this new book Hawking takes us to the cutting edge of theoretical physics, where truth is often stranger than fiction, to explain in laymen’s terms the principles that control our universe. One of the most influential thinkers of our time, Stephen Hawking is an intellectual icon, known not only for the adventurousness of his ideas but for the clarity and wit with which he expresses them.
