Great book, including for self study. Unlike other quantum mechanics textbooks that start with matrix mechanics, this book starts with the Schroedinger equation, but then ends up really nicely deriving everything else step by step. First part is theory, second part has lots of approximations and techniques like perturbation theory. The only aspect I would have loved to see more discussion of is quantum entanglement. The electron spin singlet state falls out of some nice derivation but doesn't even get called entangled until much later; the EPR paradox and the Bohm inequality are in the afterword. Other than that, great content, and really fun and engaging writing style.
