While not as good as his EM book, which to be fair is a very high bar to clear, this is good if you have a good professor to guide you through QM for the first time. There are two ways of approaching QM: the Shrodinger equation or the matrix mechanics of Heisenberg. Most students will find Schrodinger's more intuitive as wave equations and differential equations are more familiar to the average physics student at least it was for me. The other way requires some familiarity with linear algebra which is not as intuitive but equally powerful if not more so. The books that take this approach are by Shankar and Sakurai at a more advanced level and Townsend at the junior undergrad level.<br>If you are learning on your own or have a professor lacking in teaching ability, I recommend the excellent lecture videos on youtube by Brant Carlson. They can be found under the title Carthage PHY4200 or under his name. His lectures are faithful to the book and I found them to be very clear and Dr Carlson solves some problems in the lectures. Of course, you MUST do the exercises in the book on your own to really understand the material as physics is learning by doing and not a spectator sport.<br>Interestingly, I got my copy of this textbook because the previous owner somehow was so frustrated with it that s/he tore the binding at the index of the book. Luckily, it was an easy fix with some clear packing tape and I have an otherwise very good condition hardcover for $25.
