An excellent text. The postulates of quantum mechanics and the mathematical underpinnings are discussed in a clear, succinct manner. The author introduces major additions and updates key presentations in this classic text. New features include an entirely rewritten mathematical introduction, a discussion of Time-reversal invariance, and extensive coverage of a variety of path integrals and their applications.
