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 a landmark volume in scientific writing. But for readers who 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—A Briefer History of Time is Professor Hawking’s response.
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

Gets somewhat caught in the switches
By A Reader
I do not have a science background, and I did not read a Brief History of Time when it was originally published or thereafter. So this review is written to a fairly small category of potential readers -- those like me with an interest in modern physics but without much background.
I thought the book was exceptionally well written, and it was outstanding in places. It was certainly a very fun read, and I think it achieves a very lofty goal -- making liberal arts grads like me understand both the desirability and potential implications of reconciling general relativity and quantum physics. But, overall, I thought it tried to walk too fine a tightrope between discussing complex subjects and at the same time attempting to be as conversational and accessible as possible. That is a lofty goal -- hard to achieve I think. The reality is that some of these concepts are very very difficult to the uninitiated, so the cursory treatment the authors sometimes give them, in their attempt to make the book accessible and to live up to the "briefER" in the title, actually at times makes the book harder to understand, not easier. It is most acute in the book's introduction to uncertainty, quantum physics, and understanding the implications of interference experiments. More detail, not less, was needed here to reach the authors' goal of accessibility. Don't get me wrong, I wasn't seeking a text heavily laden with mathematics or equations. I just think the overriding editorial doctrine with this book was to condense wherever possible, and that is just not always possible or desirable.
All that said, the book achieves it purpose: To take some of the amazing intelligence and insight of one of the world's most important thinkers, squeeze it into understandable packets, and give us ordinary folk some insight into the exciting times in which anyone interested in the Universe and its fundamental questions live. But to steal a little from Einstein, I thought the authors didn't quite follow the second half of his famous exhortation to make everything as simple as possible, but no simpler.

A Science Classic Now made Accessible to Everyone!!
By STEPHEN PLETKO
+++++
"In this book are lucid revelations on the frontiers of physics, astronomy, cosmology [the study of the universe as a whole], and courage [Dr. Stephen Hawking has ALS, also called Lou Gehrig's disease or motor neuron disease contracted when he was young and now is wheelchair bound]. This is also a book about God...or perhaps about the absence of God. The word God fills these pages. Hawking embarks on a quest to answer Einstein's famous question about whether God had any choice in creating the universe. Hawking is attempting, as he explicitly states, to understand the mind of God. And this makes all the more unexpected the conclusion of the effort, at least so far: a universe with no edge in space, no beginning or end in time, and nothing for a Creator to do."
These are the words in the last paragraph of the introduction to Hawking's very first or original book "A Brief History of Time" (1988). These words were written by the late, great Dr. Carl Sagan. (In his introduction, Sagan calls Hawking a "legend.")
Nothing has changed with this new book with respect to what Sagan says above. But as a reader of Hawking's first book, I did notice welcome changes.
First, this new book is more concise. This does not mean this book is drastically shorter than the original. This new book is about twenty pages less than the original. Also this new book contains one more chapter than the original! What this book does is cut out extraneous technical detail from the original and focuses only on the most important concepts but still maintains the essence of the original. Thus, the book seems much more concise.
Next, and this is very important, this book is more accessible. The important concepts mentioned above, I found, are explained much more clearly thus increasing this book's readability in order to achieve Hawking's (and collaborator Leonard Mlodinow's) goal: "to share some of the excitement of...[scientific] discoveries, and the new picture of reality that is emerging as a result."
Third, this book is illustrated throughout with color illustrations. Actually, the original book was also illustrated but the new illustrations are, I feel, more easier to grasp. (I only have a complaint with the first illustration in this new book because it doesn't illustrate the point it's trying to make.)
Finally, this book is actually updated with respect to the latest theoretical and observational results! For example, this book describes recent progress that's been made in finding a complete unified theory of all the forces of physics and describes the progress made in string theory (technically called superstring theory). Observational material comes from the Cosmic Background Explorer (COBE) satellite and by the Hubble Space Telescope. Thus, even though I read the original book, I still learned much from this book.
As with the original book, this book contains a helpful glossary and an appendix briefly outlining the lives of Albert Einstein (1879 to 1955), Galileo (1564 to 1642), and Sir Isaac Newton (1642 to 1727). (Notice that Newton was born in the same year Galileo died. Hawking was born in 1942, three hundred years after the death of Galileo.)
Here are the names of the chapter titles:
(1) Thinking about the universe.
(2) Our evolving picture of the universe (Discussion of Galileo starts here.)
(3) The nature of scientific theory.
(4) Newton's universe.
(5) Relativity. (Discussion of Einstein starts here.)
(6) Curved space.
(7) The expanding universe.
(8) The Big Bang, black holes, and the evolution of the universe. (It is thought that the Big Bang is how the universe began. A black hole is a region of space or more correctly space-time, where nothing, not even light can escape, because gravity is so strong.)
(9) Quantum Gravity. (This is a theory that merges quantum mechanics that is a theory that deals with the very small with general relativity that is a theory of the very large and that incorporates gravity.)
(10) Wormholes and time travel. (A wormhole is theoretically a thin tube of space or space-time connecting distant regions of the universe.)
(11) The forces of nature and the unification of gravity. (The forces of nature are electromagnetism, the weak force of radioactivity, the strong force that binds the atomic nucleus together, and gravity. The first three forces can be combined or unified but gravity seems to stand on its own.)
(12) Conclusion. (Last words in this chapter: "then we would know the mind of God.")
Finally, this book is not referenced. However since Hawking is Lucasian Professor of Mathematics at Cambridge University, a post once held by Newton and Sagan witnessed his accepting this position in 1974, I think I can safely take Hawking at his word.
In conclusion, this book is a reorganized version of a science classic that is now more accessible, more concise, better illustrated, and updated with the latest research. It is not to be missed!!
(first published 2005; acknowledgements; forward; 12 chapters; main narrative 160 pages; appendix; glossary; index)

rather like plumbing
By David A. Baer
When I mentioned to my friend Carver Yu that I was reading this book, he scrunched up his face in the way that only a man who knows the field well can do and commented, `Well, of course, that book contains a fair bit of metaphysical speculation.'
Precisely.
That is what makes Hawking's attempt to simplify his original one-syllable-less A Brief History of Time such a beguiling reader for a non-specialist like me. Call it metaphysical speculation or call it a daring attempt to translate the astrophysicists' language into yours and mine without losing the power of asking us to imagine a world nearly completely different than the one we thought we lived in. Call it what you want, it's still a read well worth the effort it requires.
Don't shy away from finishing this book if you don't understand it all. Allow it the chance to paint an impressionistic portrait of what physicists--many of them justly awe-struck by the object of their inquiry--believe that they see `out there' when some of humanity's best minds ask the fundamental questions and follow the theories (theirs is a theory-rich pursuit) where they lead. Many of those theories, as Hawking describes them, will sound like nonsense. Unless sense is different than we thought.
When I was at Cambridge, I used to bicycle past the severely disabled Stephen Hawking in his wheelchair, followed by his personal nurse, as he wheeled between home and office, his mind no doubt drifting far from the concrete course of his wheelchair across the Commons. One wonders whether paragraphs of Briefer History and other of his works were taking shape as our paths crossed.
Metaphysical speculation for those who dare to imagine things they may not fully understand. Things like wormholes, peabrains, and a universe curved so severely that words almost fail in the explaing of it.
If that sounds provocative enough to justify the effort, this book is for you.
