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 book 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. 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 superstring theory and p-branes may hold the final clue to the puzzle.  — Foyles UK
