A lovely, masterly text on quantum physics for lay people. The book is intellectually honest, explaining the concepts of the quantum world in a way that is 'as simple as possible, but not simpler.' Despite the title, the book does not scratch the surface, but goes deep into the philosophical ideas that make quantum physics so fascinating. It also tells the history of quantum mechanics and does not shy away from giving the reader a taste of the actual mathematics involved. At a time when some of the most successful popular-science books mystify instead of clarify, this is a refreshing return of the spirit of the enlightenment. Intelligent readers will love it!
