Excellent introduction to String Theory.
"String theory is the only game in town in physics departments these days. But echoing Lee Smolin's forthcoming The Trouble with Physics (Reviews, July 24), Woit, a Ph.D. in theoretical physics and a lecturer in mathematics at Columbia, points out—again and again—that string theory, despite its two decades of dominance, is just a hunch aspiring to be a theory." - Publishers Weekly
"String theory—the hot topic in physics for the past 20 years—is a dead-end, says Smolin, one of the founders of Canada's Perimeter Institute of Theoretical Physics and himself a lapsed string theorist. In fact, he (and others) argue convincingly, string theory isn't even a fully formed theory—it's just a 'conjecture.'" - Publishers Weekly
