You of course need to take anything that are his own theories with a grain of salt (the last few chapters) and I did not think he gave a very satisfactory explanation of string theory or the other various quantum gravity theories being worked on. All in all a good read as long as you are willing to put in the time for the mathematics....more

Lots of interesting ideas and fascinating examples, but irritatingly written and often overly hyperbolic in his claims.

It succeeds quite well in this task and it allows the (sufficiently dedicated) reader to gain an understanding of some of the mathematics as well as the origin of the excitement behind the theory. By its nature, it cannot cover any of the most exciting recent work, but this should not be held against it. If you took quantum mechanics in college, and now later in life want to know what all the commotion about string theory has been for the past 40 or so years, this is the best place I've found to start....more
