In this book, the author addresses selected topics in quantum mechanics that are not usually covered in books, but which are very helpful in developing a student's interest in, and a deeper understanding of the subject. The topics include two different ways of looking at quantum mechanics; three clarifying topics that students often find confusing; one classic theorem never proved in the classroom; and a discussion on whether there can be a non-linear quantum mechanics. The book can be used as supporting material for graduate-level core courses on quantum mechanics.

Offers a fresh look at quantum mechanics

Addresses topics that are fundamental to a deeper understanding of quantum mechanics

Includes a chapter elucidating the proof of Wigner's theorem
