First he taught you classical mechanics. Now, physicist Leonard Susskind has teamed up with data engineer Art Friedman to present the theory and accompanying mathematics of the strange world of quantum mechanics. In this follow-up to The Theoretical Minimum, Susskind and Friedman provide a lively introduction to this notoriously difficult field, which attempts to understand the behavior of subatomic objects through mathematical abstractions. Unlike other popularizations that shy away from the weirdness of quantum mechanics, the book "Quantum Mechanics" embraces the absolute strangeness of quantum logic. The authors offer crystal-clear explanations of the principles of quantum states, uncertainty and time dependence, entanglement, and particle and wave states, among other topics, and each chapter includes exercises to ensure thorough understanding of each area. Like the first volume of The Theoretical Minimum, this volume runs in parallel with Susskind's ongoing series of continuing education courses at Stanford University. An accessible yet rigorous introduction, the book "Quantum Mechanics" provides a toolkit for amateur scientists to learn physics at their own pace.
