#1 NEW YORK TIMES BESTSELLER A landmark volume in science writing by one of the great minds of our time, Stephen Hawking's book explores such profound questions as: How did the universe begin--and what made its start possible? Does time always flow forward? Is the universe unending--or are there boundaries? Are there other dimensions in space? What will happen when it all ends? Told in language we all can understand, A Brief History of Time plunges into the exotic realms of black holes and quarks, of antimatter and "arrows of time," of the big bang and a bigger God--where the possibilities are wondrous and unexpected. With exciting images and profound imagination, Stephen Hawking brings us closer to the ultimate secrets at the very heart of creation.… (more)
User reviews
Does the book succeed? I do not think so. But it makes a worthwhile attempt that I think will wet the appetite for some. It didn't succeed with me because it was a bit too dry and technical. In many places I had trouble following the explanation of theories. For example, theories that describe particles as having spins of 3/2, or even 1/2. There are particles that only spin left, and particles that can only spin twice around. Also difficult is the description of space as having more than four dimensions, or singularities where matter is crushed into a single point in space. These are all very strange properties of our universe. They have not been observed and are only theories. This makes the visualization of them very difficult. I also caught myself wondering how important all of this is, and whether I should bother spending any more time understanding. I won't be using this knowledge, and it isn't very useful to me. I found myself many times pushing onward with the book past issues or topics that I simply couldn't understand.
In the end I suppose it is very interesting to learn and ultimately to appreciate that our universe is a very strange and still poorly understood place. I am very glad that Stephen Hawking wrote this book. I think it speaks very much to his abilities as a professor, a scientist, and a disabled person navigating the world.
At it's core, this book offers a

I absolutely loved this book (so much, in fact, that I read it twice) and can't wait to read more from Hawking. I recommend this book to anyone interested in understanding the universe in which they live ranging from the extraordinarily vast (general theory of relativity) to the extraordinarily small (quantum mechanics) and the search for the Theory of Everything (uniting the two theories in a quantum theory of gravity).
Hawking gives the history of the science surrounding the ultimate questions of the universe starting from the arguments of Aristotle in 340 B.C. for a round earth to the very strange land of today's physics of quantum mechanics with its different colored quarks and antimatter on the micro level and the strange interstellar beasties of relativistic physics of dark matter, black holes, quasars, and neutron stars and the very weird string theory that might unite both. I do think his explanations are lucid and elegant. I can't remember a better description of Einstein's General Theory of Relativity by explaining its historic relationship to Newton and how the theory tried to answer questions about the relationship between space and time. And Hawking manages to explain some sophisticated concepts without loading the book with jargon or equations. Hawking was also great at explaining how the theory of Relativity fits--or rather doesn't fit--with Quantum Mechanics and the search for a theory that could unify them both. I'm not saying I understood everything in the book. The concepts are counter-intuitive and hard to digest, and there's only so far you can go in explaining difficult subjects in simple terms to people lacking the background. But I understood it better, and certainly got the implications Hawking spelled out.
About the only stylistic quirk I had an issue with was Hawking's refusal to use the B-word. (A Briticism?). I find it a lot easier to wrap my mind around ten billion than "ten thousand million." The edition I read was written in 1996, updated from the first edition from 1988 which was a enormous bestseller. In the Foreword to that revised edition, Hawking wrote he thought that "within a few years we should know whether we can believe that we live in a universe that is completely self-contained and without beginning or end." Hawking definitely leaves me wanting to read more to find out the verdict. Worth reading, although not always easy to grasp.

I also enjoyed this book for other, perhaps less obvious, reasons. I'm a very textually-oriented reader, and while a few people have told me that they think mostly in pictures, I've never quite understood what that might feel like. "A Brief History of Time," however, is the sort of book that forces you into that mode of thinking -- it all but guides its readers through the formulation of a set of science-related mental images. It's challenging, if you're not accustomed to thinking that way, but imagining how, say, light particles act at the rim of a black hole is a fun exercise nonetheless. Hawking deals with extremes: the infinitesimally tiny, the awesomely large. There's a chilling sort of grandeur to many of his descriptions of the universe, which is largely composed of huge expanses of cold, empty space. Some readers might find some of Hawking's descriptions disconcerting, but there's a hint of the sublime here, too. "A Brief History" made me very aware that my mind spends most of its time considering things on a relatively familiar human scale; it is, perhaps, a sign of Hawking's intelligence that he can consider the immensity of the universe without having his mind simply boggle at its size. There's a lot in this book that is, from an anthropomorphic perspective, pretty humbling, a blow to anyone's ego. Still, maybe it's not a terrible thing to be asked to consider oneself a tiny speck in an infinitely large and indifferent universe, at least once in a while.
Hawking has a nice way of not only explaining theories of time, but also illustrating why one might care about these theories. In the end he talks about how these theories are confusing for most people, but speculates that if a unified theory is developed, it will make it possible for the general population to understand.
"Then we shall all, philosophers, scientists, and just ordinary people, be able to take part in the discussion of the question of why it is that we and the universe exist. If we find the answer to that, it would be the ultimate triumph of human reason---for then we would know the mind of God."
These leaves the question, which Hawking does not really address, of whether we really need a unified theory. But it does illustrate why people like Hawking and Einstein really WANT a unified theory.
Although the he writes simplistically the content is certainly mind blowing. I recommend this book for people who have had a partial scientific background and a definite interest in physics. I have read the book three times and I would be exaggerating if I said I understand it completely. Despite this it is still an excellent book and I recommend to anyone with scientific interest.
With that admission out of the way, this book is a lot of fun. Hawking, an uber-genius, has an almost boyish sense of wonder at the makeup of the universe. Note that since the writing of this book, the author has altered some of his theories, especially with regard to singularities.
*By which I mean that I grasp the concepts in general terms but would have a hard time teaching them to anyone else and certainly could not draw conclusions from or otherwise use my knowledge.
It's a shame that those copies go unread... Hawking's book is a pretty readable lesson on physics and the general ideas behind work relating
I've never taken a physics class and mostly found the book interesting. As his thoughts grew more complex at the end of chapters, I did find myself getting a bit lost (mainly because some of these concepts are beyond me.) However, Hawking frequently "dumbs things down" by giving concrete real world examples that help at least provide a general idea.
Glad I read this one, though it did confirm that a career path in science was not for me!
difficult to stay on his plan of thought regarding space and time; he presents theories of how the universe began & will end; references to God are from New Age perspective vs. Creator
