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
Product Description
"[Greene] develops one fresh new insight after another...In the great tradition of physicists writing for the masses, The Elegant Universe sets a standard that will be hard to beat." --George Johnson, The New York Times Book Review
In a rare blend of scientific insight and writing as elegant as the theories it explains, Brian Greene, one of the world's leading string theorists, peels away the layers of mystery surrounding string theory to reveal a universe that consists of 11 dimensions where the fabric of space tears and repairs itself, and all matter-from the smallest quarks to the most gargantuan supernovas-is generated by the vibrations of microscopically tiny loops of energy.
Green uses everything from an amusement park ride to ants on a garden hose to illustrate the beautiful yet bizarre realities that modern physics is unveiling.Dazzling in its brilliance, unprecedented in its ability to both illuminate and entertain, The Elegant Universe is a tour de force of science writing-a delightful, lucid voyage through modern physics that brings us closer than ever to understanding how the universe works.

 Excellent resource for the layman.... September 7, 2008
Don't know much about new physics? This is stuff I didn't get the first time around--they weren't discussing it back then since all of us were running from the dinosaurs....
Anyway, Greene has a good descriptive edge that will keep you reading even if the subject of string theory and quantum physics gets a little too deep. Even if you've had physics 1 and 2 in college, I guarantee that those basic classes won't cover anything mentioned here, but you'll better have the mindset to take in this information.
Good luck! And remember that a college education is never a waste--if you really think how to use it well. A science background will certainly make you a better television series writer.
 Quantum Foam and Hidden Dimensions August 28, 2008
There were parts of this book that were difficult to grasp, but what I liked about it was it's explanation of quantum foam and hidden dimensions. Quantum foam is a general concept in physicis that I had heard of, but didn't really understand. The author explained the meaning of it in a clear and succinct way, and showed why it is such a stumbling block for a unified theory. Also, his description of hidden dimensions made that concept much clearer for me. A good book if you are interested in physics and cosmology.
Don't know if its the subject matter or Greene... July 26, 2008
...but this stuff is good. Greene goes a little overboard with the analogies, but it's almost necessary to do so with such technical material (at least when it's obvious his target reader is someone with little collegiate-level training in physics). I personally love anything that attempts to explain our physical world, and Greene does just that in a very original and sincere way. String theory is a hard concept to grasp -and quantum mechanics is even harder, but after reading this book two times through, the information really begins to sink in. Most people are simply unaware of the possibility of additional dimensions, or at least, are aware of them but believe they only exist in science fiction. I can't wait for technology to catch up to the claims these scientists are making. I advise anyone to read this book. Good intro to the subjects.

just read lee smolin's book.
The Trouble With Physics: The Rise of String Theory, The Fall of a Science, and What Comes Next (Paperback)
over 30 years,the gang of stringers have been trying to find any evidence even at atomic level for their theory , but they failed.
better to read science fiction novels..
Elegant Theory for an Inelegant Universe July 10, 2008
3 out of 3 found this review helpful
Brian Greene provides an excellent introduction to the topic of superstring theory, its history and evolution; its current status, achievements and obstacles; and its areas of focus for future study. The book is written for the layman, in a style that is honest, clear and concise, using numerous real-world examples to explain the basic theories, and excludes mathematical explanations as much as is possible. The early chapters on special relativity, general relativity, quantum mechanics, and quantum electrodynamics are brief and superficial and serve more as historical backgound to the main focus of the book which is superstring theory. Consequently, the book is somewhat biased in that it does not look at alternative views of the nature of the universe, on the assumption that superstring theory may eventually prove to be the theory of everything. This is because the primary goal of superstring theory is to combine general relativity (theory of the very large) and quantum mechanics (theory of the very small) and provide a unified theory of the four fundamental forces of nature - the weak, strong, electromagnetic, and gravitational forces.
The main chapters on superstring theory and M-Theory can be difficult to understand, even to accept as valid, for the layman, but keep in mind that string theory is extremely complex, not fully developed, virtually impossible to test, and consequently, not fully understood at present. The core of superstring theory is that all matter in the universe is made up of one(2,3,etc)-dimensional vibrating strings and hidden dimensions which currently cannot be observed or measured, and may never be. Consequently, matter is not infinitely small but has a very small finite size. Nor is matter and energy limited to the 3-dimensional world we live in, but can occupy up to 6 or 7 higher dimensions that are hidden from our everyday experience.
This book is well worth reading, but whether the layman walks away with a better understanding of the universe after this introduction to superstring theory is debatable. What the layman may walk away with after reading this book is a myriad of questions regarding the very assumptions upon which superstring theory is based. That superstring theory is elegant, and its complex mathematics are elegant, there is no doubt, but whether the universe is also elegant will depend on the validity of superstring theory as a true description of our universe.
Here are some questions from a layman reader:
1. If we know that observing a small particle changes its position and velocity, and we know how it changes, then we should still be able to observe it.
2. Where do vibrating strings get there energy from?
3. The hidden curled-up dimensions seem to exist at the micro level. Why do they not exist as extensions of our four spacetime dimensions, in a way that encapsulates them, at a macro level?
4. The theory is now up to 11 spacetime dimensions. Is it due mathematical convenience or limitation? Does it really matter if there are 11, 11 million, or an infinite number of spacetime dimensions?
5. Using duality symmetries, why not assume that gravity is simply a phase transition of the other 3 forces (weak, strong, electromagnetic)?
6. Does a large mass spinning body create friction, and/or a charge, with its surrounding space that would help to explain gravity as more than the mere warping of space?
7. If there is a large black hole at the center of our galaxy, should not our galaxy be shrinking, and cant this be measured?
8. We seem to understand how black holes are created, but not how they die. Why not assume that black holes simply reverse themselves after taking in a suffient amount of matter and energy, and releasing it in the form of a mini-big bang?
9. Why assume that the universe was created in a big bang. Aspects of superstring theory seem to suggest that the universe may be a perpetual, self-sustaining entity. While everything within the universe can change, including the universe expanding and contracting, the universe itself is a constant.
10. Are particle accelerators dangerous? Clearly in an attempt to experimentally verify superstring theory, physicists are going to smash particles not just to create new particles predicted by theory, but to try and tear the fabric of space, or to open a portal to a higher dimension, or even to try and create a mini black hole. Of course this does not seem to be a problem for superstring theory which suggests that most disturbances in the universe eventually get averaged out, zeroed out, smoothed out, smeared out, annihilated out, or simply self-repair themselves.
