When I was studying quantum mechanics, I quite often went to this book for a very different perspective on a lot of the details. I found it to be exceptionally well written and had a seemingly different approach from the typical college or graduate level quantum mechanics textbook. We had a copy in one of our department libraries, if you can get your hands on one, I recommend giving it a read when you want a new perspective on an academic quantum mechanics concept :)

I am far enough away from that part of my life, I apologize for not being able to give a more detailed and convincing testimonial for this book.
