Like prior editions of the book - but even more so - A Briefer History of Time will guide non-scientists everywhere in the ongoing search for the tantalizing secrets at the heart of time and space . . . This is Stephen Hawking's somewhat 'briefer' account of his up-to-date and most recent scientific observations and findings. A great companion to his original worldwide bestseller, A Brief History of Time. From curved space to quantum theory, the authors have expanded on areas of special interest and recent progress, such as developments in string theory and exciting progress in the search for a force of complete, unified theory of all the forces of physics. Thirty-eight full-colour illustrations enhance the text and make A Briefer History of Time an exhilarating addition in its own right to the literature of science.
