In The Theoretical Minimum, world-class physicist Leonard Susskind provided a brilliant first course in classical mechanics, offering readers not an oversimplified introduction but the real thing - everything you need to start doing physics, and nothing more. Now he returns with the next challenge that every aspiring physics buff must tackle: quantum mechanics. Unlike most popular physics books, Susskind and his co-author Art Friedman teach the maths and equations that are essential to any real understanding of quantum mechanics. Combining crystal-clear explanations, witty and helpful dialogues, and basic exercises, Quantum Mechanics is, to paraphrase Einstein, as simple as possible, but no simpler.
