A Briefer History of Time [平装]

From One of the Most Brilliant Minds of Our Time
Comes a Book that Clarifies His Most Important Ideas

Stephen Hawking’s worldwide bestseller, A Brief History of Time, remains one of the landmark volumes in scientific writing of our time. But for years readers have asked for a more accessible formulation of its key concepts—the nature of space and time, the role of God in creation, and the history and future of the universe.

Professor Hawking’s response is this new work that will guide nonscientists everywhere in the ongoing search for the tantalizing secrets at the heart of time and space.…

Although “briefer,” this book is much more than a mere explanation of Hawking’s earlier work. A Briefer History of Time both clarifies and expands on the great subjects of the original, and records the latest developments in the field—from string theory to the search for a unified theory of all the forces of physics. Thirty-seven full-color illustrations enhance the text and make A Briefer History of Time an exhilarating and must-have addition in its own right to the great literature of science and ideas.

From Publishers Weekly
Starred Review. In the 17 years since the publication of A Brief History of Time, Dr. Hawking's bestselling exposition of physics, new data from particle physics and observational astronomy have shed light on efforts to find a Grand Unified Theory of Everything that Hawking and Mlodinow use to enhance and update their answers to basic questions about the universe: where it's going and how it began. Discussed at length are the mysterious dark matter and dark energy-both of which can only be observed by their gravitational effects and are believed to make up 90 percent of the universe. Another area of research that has exploded in the past 20 years is string theory. Hawking and Mlodinow provide one of the most lucid discussions of this complex topic ever written for a general audience. Readers will come away with an excellent understanding of the apparent contradictions and conundrums at the forefront of contemporary physics. Recognizing that much of their audience will also be science fiction buffs, they include a chapter on the possibility of time travel. "Don't bet on it," the authors advise. Throughout these discussions, the authors maintain the same wry, lively tone that made the original Brief History such a delight. They close with a discussion of where physics ends and philosophy begins, "Why does the universe exist at all?" They cannot provide the answer, but they do provide an immense amount of food for thought. Highly recommended.

From Scientific American
Hawking's A Brief History of Time, published in 1988, was a surprise best-seller but a tough read for most people who tackled it. Hawking received many requests for a version that would make his discussion of deep questions about the universe more accessible. This book does that. Hawking and Mlodinow, a physicist turned science writer, proceed by small and careful steps from the early history of astronomy to today's efforts to construct a grand unified theory of the universe.

From Booklist
Theoretical physicist Hawking became an international celebrity thanks to his cosmological primer Brief History of Time (1988), one of the twentieth century's biggest best-sellers. According to Hawking, one copy of Brief History has been sold for every 750 people on earth (move over, Scarlett O'Hara!). While Brief History amassed that sales record, however, its subject matter didn't stand still, and some kind of overhaul, Hawking and Mlodinow say, came to seem necessary. They chose to revise in the direction of lesser length, more illustration, and greater accessibility as they updated to incorporate developments in string theory, new indications that a unified theory of physics--one that comprehends gravity as well as the three other physical forces--is possible, and new observations made by the Hubble Space Telescope and the Cosmic Background Explorer satellite. Few will be sorry for their choice, for Briefer History may be the clearest introduction to physics ever, and not just because it eschews equations, though that helps. Its clarity arises from firmly adhering to the concept announced by the second chapter's title, "Our Evolving Picture of the Universe." The book is the developmental portrait--a biography, if you will--of the idea of a dynamic cosmos, which took long to catch on: even Einstein, whose relativity theories "broke" the idea as nothing before had done, clung to a cosmological constant (which, Hawking and Mlodinow show, yet has its uses) in the face of quantum mechanical indeterminacy. Like the best biographies, it's an utterly engrossing read. Ray Olson
