Explains quantum physics in a way that's not only clear, but also enjoyable. The author opens with the subjects that most physics professors have just started to examine at the end of the semester: The mysterious character of light, the valence concept in Nils Bohr's atomic model, radioactive decay, and the physics of life-defining DNA all get clear, comprehensive, and witty coverage. This book reveals the beauty and mystery that underlies everything in the universe.
