Title: The best physics divulgation book I have ever read
Review: This is a fascinating book for laymen people as well as physicists or scientists in general. It explains such a difficult theory as superstring theory with an unforeseen clarity, making lots of analogies to clearly understand the underlying concepts. Even those subjects, as relativity and quantum mechanics, which has been extensively treated anywhere else, are exposed with such a clarity that they make an intellectual 'refresh' even for expert people...The last chapters, dealing with the ampliation of superstring theory to M-theory and its aplicattion to cosmology and black holes may be a little harder to follow in a single read for the laymen, but essentialy a lot of physics developed during the last century is explained in less than 400 pages...Greatly recommended.
