After a few years of reading math-free QM popularizations, I decided to try to learn the math.  Finding a book that bridges the vast gap between the popularizations and textbooks, though, has been a real challenge.<br><br>Thankfully, this book is now available.  Yes, it's difficult but it's far more accessible than a textbook.  The authors have really made an effort to offer insight into what is inherently a very abstract and mathematical subject.  Like FLP-III (Feynman's Lectures on Physics), the approach is to start with "spin-first" and then work "backwards" to the Schrodinger equation, which is the starting point for most textbooks (that way, the harder math is deferred until later).  However, QM:TM is more modern and easier than FLP, which is after all, meant for future physicists.<br><br>If you don't know any advanced math (calculus, complex numbers, etc.) then you should pass on this book.  But the "math-divide" has now been bridged by this book, which is destined to be a classic.<br><br>Note:  I didn't care much for TM: volume I (it was too rushed and brief) but that's not the case with volume II.  The only con is there's no companion site (as far as I know) with solutions to the exercises.
