This book is great. I recently bought this book because the television shop, Numb3rs sparked an interest for me and alot of topics covered in this book were talked about on Numb3rs. If you like quantum mechanics or wanna learn quantum mechanics, this is the book for you. The only problem for this book is that the reader will need some experience in physics, math and mechanics, not to worry as there's no need for all the high class math physics, just some experience.
