Almost 5 Stars

Although I felt this book was excellent and covered all the bases there were a few areas that lacked for me and I couldn't quite give it 5 stars. The book started out phenomenally and the section on quantum mechanics was the best that I've read. The analogies that Mr. Greene used made the concepts clear and comprehendable but there were a few chapters in the middle where he used no analogies and I found myself completely lost even after re-reading the chapters. I might be too much of a layman for this book and that would certainly not be Mr. Greene's fault. There were additional parts of the book where I found myself easily destracted and those chapters were almost a chore to finish. Over all I think parts of this book are great for readers who are just begining to study this subject but other whole chapters are definately not.

First half zipped along with insight after insight.

First half zipped along with insight after insight. Second half got a bit heavy and bogged down. Overall I'm glad I made it through.

science or science fiction?

"Theoretical physicist is the one whose experiments don't work".
So says my friend, an engineer by profession, and The Elegant Universe fully confirms this view - more, since we learn that the theories of modern physics are beyond our technological ability to test them experimentally.
The theories themselves are indeed very elegant, composed with great care for estetics and symmetry, and well illustrated by pictures. Nonetheless, we are left with an impression that most of it is the stuff of phantasy, and just as one calculation will "prove" some idea, another set of equations will "disprove" it with identical claim to "scientific truth". I've put all this terms in quotes because the maybe factor of all proofs is too strong to take the presented theories seriously. The author admits that all the calculations are based on approximations and numerous assumptions, raising from still more approximations and probabilities. And when the result is absurd, the theorists quickly solve the problem by inventing one more spatial dimention, not accessible to our perceptions because it never expanded from its initial state.
Actually, the whole string theory deals with aspects of reality not accessible to our perceptions, and not provable by any experiments. Is it still reality or already a fiction? We don't know, and chances are will never know.
With all this, it is indeed an extremely elegant text, beautifully written and holding our attention all the way to the end. I just wish the author did not say all of the time that string theory had been "discovered", since for all we know theories are not material reality, such as a continent of America or a rare species of a butterfly, and so they cannot be discovered, theories can only be conceived, invented, or created. This lexical misuse is eye-catching due to the prevalence of hypotheses over the facts so stronly visible in string theory.

In this brilliantty articulated and refreshingly clear book, Greene, a leading string theorist, relates the scientific story and the human struggle behind the search for the ultimate theory. String theory, as the author vividly and easily describes, reveals a vision of the universe that is sending shock waves through the world of physics. Thrilling and revolutionary ideas such as new dimensions hidden within the fabric of space, black holes transmuting into elementary particles, rips and puncutures in the space time continuum, gigantic universes interchangealbe with minusclule ones, and a wealth of others are playing a pivotal role as physicists use string theory to grapple with some of the deepest questions of the ages.
