[.ca] The Elegant Universe: Superstrings, Hidden Dimensions, ... (ISBN 0375708111)

From Amazon.com:
There is an ill-concealed skeleton in the closet of physics: "As they are currently formulated, general relativity and quantum mechanics cannot both be right." Each is exceedingly accurate in its field: general relativity explains the behavior of the universe at large scales, while quantum mechanics describes the behavior of subatomic particles. Yet the theories collide horribly under extreme conditions such as black holes or times close to the big bang. Brian Greene, a specialist in quantum field theory, believes that the two pillars of physics can be reconciled in superstring theory, a theory of everything. Superstring theory has been called "a part of 21st-century physics that fell by chance into the 20th century." In other words, it isn't all worked out yet. Despite the uncertainties--"string theorists work to find approximate solutions to approximate equations"--Greene gives a tour of string theory solid enough to satisfy the scientifically literate. Though Ed Witten of the Institute for Advanced Study is in many ways the human hero of The Elegant Universe, it is not a human-side-of-physics story. Greene's focus throughout is the science, and he gives the nonspecialist at least an illusion of understanding--or the sense of knowing what it is that you don't know. And that is traditionally the first step on the road to knowledge. --Mary Ellen Curtin

needed more about the elegant universe:
This books is over-rated, but still better than most books on the subjects he covers. I gave it two stars to get your attention. It is actually a 3 or 4 star book. I was dissappointed because the title suggested I'd read more about the mysteries of the beginning of the universe and some of the philosophical issues pertaining to the nature of existance and ultimate reality. While the author did give me some good mindfood at the end of the book, the coverage was too brief and far too restrained. I think he was aware of his peers reading it and was being too conservative. I skimmed a lot. I kept an eye out for places where he quit trying to teach me details and made some interesting comments. I'll give him credit--there were plenty of facinating paragraphs---but they were hidden in page after page of boring stuff. Lets face it, this is arcane stuff! But the implications are interesting, at least to me. I think the book should have been about half the length. I personally don't think it is possible to understand things like relativity without working some problems. When I took physics, I had to work a few problems to think about the stuff deeply enough to "get it." I don't think many readers are looking to work that much--most of us want a stimulating read. And as the author mentions, many believe that no one really understands quantum mechanics. Also, I did not like the analogies as much as some other readers. I recommend this book to really really smart readers or to readers who know how to skim without losing interest. Some of the insights were worth looking for.

Detailed but biased instroduction to string theory:
Toe central problem of physics today revolves around this conundrum: Gravity is governed by Einstein's relativity theory, which requires that space-time is smooth. Gravity has been experimentally verified. Atomic forces are govered by quantum mechanics, which requires that space-time is bumpy, foamy, and irregular. These atomic forces have been experimentally verified. How can space time be smooth for gravity, and yet be bumpy for quantum machanics? Enter string theory. This book is a terrific introduction not only to string theory, but to relativity and quantum mechanics as well. The first half of the book reviews the history and development of these theories, since they are a fundamental component of string theory. In particular, Greene's treatment of relativity uses some outstanding analogies to explain time dilation and gravitational warping. I thought I understood the basics of relativity; this book still taught me a few things. Analogies are this author's strength. He uses them at every step to avoid the need to complex mathematical formulae. There are no formulae in this book (some will think that a minus, but I view it as a plus.) Using analogies, he's able to provide a comprehensible view of what 10-dimensional spacetime would be like, and how expanding one of the other dimensions might affect life in the Universe. These 5 pages alone are probably worth the price of the book. If you want a glimpse of one of the cutting-edge areas of particle physics research without needing to study math for 10 years, this book can give it to you.

Amazingly Clear:
I was very pleased early into the reading of this book. This was for example, the clearest explanation that I have ever read on the topic of time dilation in relativity. I have read a lot of these sorts of books, but this one presented ideas so clearly it is as though I haven't been exposed to them before. Overall, I thought that it was the best book that I have read in physics period.

The science of wonder:
I have to credit Brian Greene. He did what I thought was the impossible: he got me interested in science. I've been a liberal arts-type since I can remember. The exact rules and laws of science always left me kind of cold, and so I found myself drawn to literature, poetry and music as the more complete descriptors of human experience. But last Fall, I couldn't sleep one night and ended up staying up until dawn watching THE ELEGANT UNIVERSE. It was amazing and captivating. It got me excited in a way "science" hadn't since I was a kid, fascinated with the imaginative possibilities of space travel. I was hooked and had to get the book. The tv program proved to be a great distillation of the book, but if you saw the program and your interest was piqued by the magical dance of superstrings and the mind-bending extra dimensional possibilities, you'll enjoy the full feast of Greene's book even more. THE ELEGANT UNIVERSE is an enormous feat. It marries the rigor of scientific enquiry with the elegant, at times poetic, presentation of literature. Greene is such an able and down-to-earth explainer of complicated mathematical concepts that he makes even the most dyed-in-the-wool math hater think about signing up for some evening classes at the local college.
