I think people who say they read this book are lying. (  )1   woodge | Nov 20, 2009 |  15 August 1999 The first chapters were excellent general introductions to quantum theory and relativistic physics, and an explanation of why these two theories conflict at the extremes of energy and size. The rest is a nonmathematical account of string theory, the current favorite approach to putting together quantum physics and relatively. Superstring theory conceives of physical quantities as vibrating "strings" in multidimensional space. It uses very theoretical mathematics, such as 10-dimensional Calabri-Yau space, and became quite incomprehensible without the math (  ) neurodrew | Oct 4, 2009 | I read The Elegant Universe to hopefully increase my knowledge of black holes what I got instead was a review of Newton and Einstein's theory's and the introduction of a new theory, String Theory or as some call it, The Theory of Everything which introduces the possiblity of the existence of 11 dimensions. The book ends with work currently being done at Fermilab and CERN where experiments are being done to collide atoms and possibly simulate the Big Bang. Although the book barely touched upon Black Holes it did introduce new information that further peaked my interest in this sector of science in easy to read for laymen terms.

| Descrição do livro |
|
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
