Record Setting, March 4, 2004
I've never written a review before, but I have enjoyed browsing reader's comments on books I read or teach from. While reading the review that claims this new book to be a "dumbing down" of The Elegant Universe, and to have "no new material", I felt I had to set the record straight. For the record: I teach Physics for Poets class in a local community college, and use The Elegant Universe as one of our books. Next year I will add Fabric of the Cosmos to the syllabus since it has at least 80% new material, and the overlap with The Elegant Universe is done in a new way that I have not seen in any other book, The Elegant Universe or otherwise. The reviewer says that "200 pages are spent reviewing Newton and Einstein" which is a factual error. It is just over 50 pages, and a fascinating new angle known as Mach's principle is used. For the reviewer to say that "spooky action at a distance" is in Elegant, is also a factual error. He must be thinking of another book. This (huge) subject, entanglement, was not covered in the Elegant Universe as I know for sure, since in the past I have had to assign other books for these ideas. I might add that the discussion of entanglement in Fabric goes far ahead of any other since it proves Bell's theorem, without math! I didn't think that was possible! The main theme of The Arrow of Time which runs through Fabric, is not touched on at all in Elegant, nor are the questions of whether space and time are real or just ideas. If someone is looking for a direct sequel to Elegent, this is not that book. Fabric is a monumental work of its own and should be read as such. For other suggested readings: Kip Thorne's Black Holes and Time Warps, Janna Levin's How the Universe Got its Spots.

The One Book to Read, March 16, 2004
I loved The Elegant Universe. I loved The Fabric of the Cosmos even more. In showing the state of the art of unified theories, The Elegant Universe explained alot of physics with unsurpassed clarity. Yet, there were discoveries I had read something about in other books that The Elegant Universe did not discuss, and I longed for Brian Greene to bring his powers of explanation to these subjects too. (I even wrote him an email saying so). The Fabric of the Cosmos answers my longing in abundance. This book not only covers relativity but also the long debate about Mach's principle and what "space" means. It covers quantum mechanics, but goes further by taking on the debate regarding observers and measurment, and provides the clearest, most understandable discussion of quantum entanglement (the "EPR paradox) that I have ever seen in print or any other format. The chapters on cosmology are equally great, and the final sections bring the work on unification and string theory right up to the moment. I can't say this is an easy book, perhaps a little easier than The Elegant Universe, but definitely a challenge. It is worth it. By the end, the poetry of the universe is yours to behold.

The book I've been waiting for., March 4, 2004
By A Customer
I happened by chance on The Elegant Universe two years ago during one of my "learn the newest" in physics stretches. I'd read many popularizations to that point, but none could hold a candle to The Elegant Universe. The chapters on relativity and quantum mechanics were, arguably, the clearest treatment of these subjects ever written, and that really says something since this subject has been written about endlessly. I knew little about string theory at the time but found Greene's encapsulation of the theory to be among the best popular science writing I've read. So I was so happy when I saw he had a new book out. Having now finished it, I am even happier. It is a phenomenal successor to The Elegant Universe; in some ways I liked it even better. Greene's crystal clear and never a dull moment prose are out in force, with his uncanny ability to anticipate the questions the reader (or at least this reader) will have regarding material one page, and answer them on the next. There were so many times I asked myself "what about this"? only to find it answered a paragraph later. The material is also carefully arranged so that you can read it along three different strands, corresponding to different levels of background/interest. In the first strand, you can read the book, skipping the sections which Greene has indicated to be more difficult. In the second strand, you can read all sections, as I did, gaining an even greater appreciation of the ideas and related tricky points. In the third strand you can also read the endnotes which contain very detailed versions of the material covered in the main book, sometimes making use of equations. What I especially liked about The Fabric of the Cosmos, was the choice of subjects. Space and time are less esoteric than string theory, and the theme of discussing breakthroughs not just for the sake of science but, of equal importance, to assess their relevance for our intuition about reality, was both fresh and thrilling. The Fabric of the Cosmos covers an astonishing amount of new material, with the same in-a-class-by-itself level of writing of The Elegant Universe. When you finish, the world looks different. How many books can you say that about? For me, not many.
