Robert Scherrer's text provides a uniquely accessible and thorough introduction to quantum mechanics for undergraduates. It is designed from the ground up to address the changing needs of today's students taking this important and challenging course. Scherrer carefully develops a solid foundation by recapping on the required math and other basic concepts before developing all the major more advanced topics. The introductory chapters introduce the experimental evidence that historically motivated the development of quantum mechanics and explain why this topic is so central to today's science and technology. Every section starts with an intuitive explanation of quantum phenomenon, which provides a clear physical motivation for the discussion that follows. Unique Math Interlude chapters throughout the book ensure that the student has all the required mathematical skills required to master quantum mechanics. In-text worked examples provide more detailed derivations and solutions than any other book.
