In the last thirty years of his life Albert Einstein searched for a theory to describe all forces of nature in a single framework. In "A Brief History of Time" Stephen Hawking concluded, like Einstein, that science may soon arrive at the long sought after "Theory of Everything". In "The Grand Design", Professor Hawking and renowned science writer Leonard Mlodinow now convincingly argue that scientific obsession with a single new model may be misplaced. Written with the clarity and lively style for which Hawking is famous, it is an account of Hawking's quest to fuse different strands of scientific theory and asks an all-important question: How far can we go in our search for understanding and knowledge?
