Well, I bought this book about two months ago, and finally got around to reading past the first chapter or so. All I can say is, WOW. It's bloody brilliant! It actually gives you some examples and application, and then shows you the mathematics and mechanics behind it (i.e. the Schrödinger Equation isn't just thrown at you, Greenstein et. al. explain why mechanics work and then give you the equation). It's very well laid out. It does require some prerequisite of knowledge, or a serious dedication to self-study, regarding some of the concepts, but it's very well put together.
