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.
