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.
