[T]his is an excellent book written by a masterful science communicator elaborating on a subject that is his research home turf—superstring theory ... If there is anyone who can demystify the esoteric mathematics and physics of string theory, it is he. And in this wonderful little book, that is precisely what he does—explain in clear and simple terms the conceptual breakthroughs, the blind alleys and the unanswered questions—in the search for a grand unified theory of everything. Most of all, what I like best is that he remains open to the possibility that there may ultimately not be a single unifying theory after all, encoded into a single tidy equation ... The God Equation dazzles in its account of the unfinished quest for a grand unified theory ... Mr. Kaku, a consummate storyteller, provides an engaging, unvarnished account of the progression of science and the intellectual obstacles that have hampered the process of finding a theory of everything. His book presents cutting-edge ideas in theoretical physics, and primes readers to be ready when the next major breakthrough occurs. According to Mr. Kaku, that’s just a matter of time.
An expert account of the search for 'the holy grail of physics.' A veteran science writer, theoretical physicist, and lucid educator, Kaku wisely begins with ancient history, providing an illuminating minihistory of physics ... An important work about an ongoing quest that may befuddle those without a solid grounding in its scientific concepts.
