This book is very good. If you have read the first volume and know some linear algebra, you can sit down and really absorb the material in several days. Couple of notes and recommendations:<br><br>1. This book, just like the first volume, would be much more effective with its own exercises. One does not know quantum or classical mechanics if one cannot solve basic problems. The fact that this book lays quantum mechanics out in a fairly different fashion means it needs its own set of accompanying exercises "dumbed down" to the level in the book. You cannot possibly pick up a regular quantum mechanics text book and start doing exercises after reading this one. The same comment goes for the first volume as well.<br>2. Watch the videos! They patch the pieces together.<br>3. As I said for the first volume, please write one for statistical mechanics! There exists many dumbed down texts for classical mechanics and quantum mechanics. What we all need is a statistical mechanics analog!
