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. His bestseller “A Brief History of Time” introduced the fascinating world of theoretical physics to readers all over the world. Now, Hawking turns to the major breakthroughs that have occurred in the years since the release of his first book. He brings to us the cutting edge of theoretical physics, where truth is often stranger than fiction, and explains in layman’s terms the principles that control our universe. Like many in the international scientific community, Professor Hawking is seeking to uncover the grail of science the elusive “Theory of Everything” that lies at the heart of the cosmos. In “The Universe in a Nutshell”, he guides us on his search to uncover the secrets of the universe from super gravity to super symmetry, from quantum theory to M theory, from holography to duality. In this exciting intellectual adventure 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 super string theory and p branes may hold the final clue to the puzzle.
