There is perhaps no area of Physics that has garnered as much fascination as quantum mechanics, save perhaps the theory of relativity. Yet in a sense the weirdness associated with quantum mechanics is even more profound than that associated with relativity. Relativity deals with physics of very fast objects, and even though it challenges our normal way of thinking, it still preserves some of the basic intuitions of what does it mean to be a physical object, how we measure properties of those objects, and what those objects can and cannot do. Quantum mechanics, on the other hand, puts all those basic notion to a test. We are forced to reconsider even our basic understanding of what reality is. There have been many popular accounts of Quantum Mechanics over the years, and this book is yet another attempt of bringing this arcane field to the general readership. So despite what the title may say, this is not a book about Physics in general, but just about quantum mechanics. The dog from the title is author's German shepherd, and she is used as a stand-in for all the naïve, "Newtonian" ways of thinking about the world. Each chapter in the book covers a different aspect of quantum theory, and all the discussions are motivated in a light-hearted way by author's "dialogues" with his dog. These "dialogues" are meant to provide some comic relief from the otherwise technical subject matter. As such they work fine, although I am not the biggest fan of author's attempts at humor. The explanations provided in the book are actually very good - they are very well written, accessible to the general audience, and absolutely conceptually correct. This last point should not be taken for granted, as I have seen many attempts at making Physics accessible to the general audience that don't actually do justice to the actual Physics. One thing that I in particular like about this book is that it mentions several more recent experiments that have shed important light at the foundational aspects of quantum mechanics. In that respect this popular treatment is as up-to-date as they come. As a college Physics professor myself, I appreciate all the effort that the author has put into making this material accessible. As far as introductory, non-technical books on quantum mechanics go, this one clearly hits its targeted audience.
