The Elegant Universe: Superstrings, Hidden Dimensions, and the Quest for the Ult | |
Now with a new preface (not in any other edition) that will review the enormous public reception of the relatively obscure string theory—made possible by this book and an increased number of adherents amongst physicists—The Elegant Universe "sets a standard that will be hard to beat" (New York Times Book Review). 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 eleven 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.
Today physicists and mathematicians throughout the world are feverishly working on one of the most ambitious theories ever proposed: superstring theory. String theory, as it is often called, is the key to the Unified Field Theory that eluded Einstein for more than thirty years. Finally, the century-old antagonism between the large and the small-General Relativity and Quantum Theory-is resolved. String theory proclaims that all of the wondrous happenings in the universe, from the frantic dancing of subatomic quarks to the majestic swirling of heavenly galaxies, are reflections of one grand physical principle and manifestations of one single entity: microscopically tiny vibrating loops of energy, a billionth of a billionth the size of an atom. In this brilliantly articulated and refreshingly clear book, Greene relates the scientific story and the human struggle behind twentieth-century physics' search for a theory of everything.
Through the masterful use of metaphor and analogy, The Elegant Universe makes some of the most sophisticated concepts ever contemplated viscerally accessible and thoroughly entertaining, bringing us closer than ever to understanding how the universe works.

编辑推荐 Amazon.com Review
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 --This text refers to an out of print or unavailable edition of this title.
From Publishers Weekly
One of the more compelling scientific (cum-theological) questions in the Middle Ages was: "How many angels can dance on the head of a pin?" Today's version in cutting-edge science is, "How many strings... ?" As posited by s tring theory physics, strings are furiously vibrating loops of stuff. The concept of strings was devised to help scientists describe simultaneously both energy and matter. The frequency and resonance of strings' vibration, just like those of strings on an instrument, determine charge, spin and other familiar properties of energy?and eventually the structure of the universe: a true music of the spheres. There's a chance that strings are themselves made up of something still smaller. But scientists can prove their existence only on the blackboard and computer, because they are much too tiny?a hundred billion billion times smaller than the nucleus of an atom?to be observed experimentally. Brian Greene, professor of physics and mathematics at Cornell and Columbia universities, makes the terribly complex theory of strings accessible to all. He possesses a remarkable gift for using the everyday to illustrate what may be going on in dimensions beyond our feeble human perception. Just when we might be tempted to dismiss strings as grist for the publish-or-perish mill, Greene explains how they have demonstrated connections between mathematics and physics that have helped solve age-old conundrums in each field. This book will appeal to astronomy as well as math and physics fans because it probes the important insights string theory gives into hotly debated issues in cosmology. Later chapters require careful attention to Greene's explications, but the effort will prepare readers to follow the scientific advances likely to be made in the next millennium through application of string theory.

From Library Journal
These days, physicists are bubbling over with talk of strings--tiny, vibrating loops of matter, seen as the building blocks of nature, that may serve to unite the divergent theories of quantum mechanics and relativity. For the rest of us, wunderkind Columbia professor Greene provides just the sort of nervy, imaginative metaphors that make understanding snap into place.

Greene does an admirable job of translating a wholly mathematical endeavor into visual terms. Throughout his work, he writes with poetic eloquence and style. --This text refers to an out of print or unavailable edition of this title.
From Kirkus Reviews
Superstring theory may provide the long-sought unification of physics for which Einstein sought in vain. Here is a look at the current state of the quest. Greene (a professor of physics and mathematics at Columbia and Cornell) begins by pointing out the central problem of modern physics. Quantum mechanics and general relativity both work perfectly, and they cannot both be right. Relativity works for large, massive objects; quantum theory for tiny ones. Normally, the two realms can be kept separate. Yet increasingly, physics deals with phenomena such as black holes, where the conflicts are impossible to avoid. Out of the search for a more complete explanation came string theory. Its foundations were laid down some 30 years ago by Gabriele Venizano, who found that a two-century-old formula by Leonard Euler described subatomic particles more elegantly than existing theory. The relationships would make sense if elementary particles were not pointlike, but elongated and vibrating, like tiny musical stringsin one sense, a modern version of the ancient metaphor of the music of the spheres. It took a while for physicists to embrace string theory; for one thing, it seemed to predict things nobody had ever seen. And despite its formidable explanatory power, its mathematical expressions were often even more formidableGreene describes some of the equations as nearly impossible to understand, let alone solve. Still, it has the right look about it, and two waves of enthusiasm (one in the mid-1980s, the other ten years later) have convinced many physicists of the theory's probable validity. Greene deftly summarizes these findings, in areas from subatomic-particle theory to cosmology, with occasional forays into deeper waters such as the ten-dimensional structure of the universe, with several dimensions folded undetectably back into themselves. A final chapter forecasts that string theory will become the standard physical model in the next century. Entertaining and well-writtenpossibly the clearest popular treatment to date of this complex subject. -- Copyright ©1999, Kirkus Associates, LP.
