# Quantum Mechanics: The Theoretical Minimum (Paperback)

### Staff Reviews

Fair warning is given

in the introduction: this book is for “mathematically literate non-physicists”

and a “basic knowledge of calculus and linear algebra” are necessary. Susskind

and Freeman give us the bare minimum for attempting to understand quantum theory,

showing us the basic “rules of the game,” laying them out methodically and,

thankfully, not too quickly. Susskind

does not digress into any philosophical discussion whatsoever, almost achieving

metaphysical and ontological neutrality, never speculating on the quiddity of

quanta themselves. One could almost call it quantitative epistemology, a

numerical and symbolic mapping of an (almost) unbelievably abstract

territory. When I saw Anton Zeilenger speak, he swooned over the math of

quantum theory, and Susskind does show the elegance and beauty of the symbols

dancing and their almost miraculous delivery of numerical predictions. The

book also cleared up some things that have bothered me about quantum theory:

Why are imaginary numbers necessary? What is the nature of entanglement

within the formalism? What is the wave in the famous Wave

Function? What kind of a space is Hilbert space? The only real

disappointment in the book is a lack of suggested reading. I am grateful

that Susskind has taken the time to make this fascinating subject approachable

above the qualitative plane—the only way to skin the quantum cat is with math.

**From the bestselling author of**

*The Theoretical Minimum*, a DIY introduction to the math and science of quantum mechanics.First he taught you classical mechanics. Now, physicist Leonard Susskind has teamed up with data engineer Art Friedman to present the theory and associated mathematics of the strange world of quantum mechanics.

In this follow-up to the New York Times best-selling

*The Theoretical Minimum*, Susskind and Friedman provide a lively introduction to this famously difficult field, which attempts to understand the behavior of sub-atomic objects through mathematical abstractions. Unlike other popularizations that shy away from quantum mechanics' weirdness,

*Quantum Mechanics*embraces the utter 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 mastery of each area. Like

*The Theoretical Minimum*, this volume runs parallel to Susskind's eponymous Stanford University-hosted continuing education course.

An approachable yet rigorous introduction to a famously difficult topic,

*Quantum Mechanics*provides a tool kit for amateur scientists to learn physics at their own pace.

### About the Author

**Leonard Susskind**has been the Felix Bloch Professor in Theoretical Physics at Stanford University since 1978. He is the author (with George Hrabovsky) of

*The Theoretical Minimum*, as well as

*The Black Hole War*and

*The Cosmic Landscape*. He lives in Palo Alto, California.

**Art Friedman**is a data consultant who previously spent fifteen years at Hewlett-Packard as a software engineer. A lifelong student of physics, he lives in Mountain View, California.

### Praise For…

"If you're ever banished to a desert island and allowed to take just one book, here it is. Given enough time, with no distractions, you could use it to eventually master quantum mechanics."—

*Science News*"Susskind and Friedman's persuasive overview--and their insistence on explaining...exactly what it is that is strange about quantum mechanics--may be just what is needed."—

*Nature*"If you want to know how physicists really think about the world, this book is the place to start."—

**Sean Carroll, author of***The Particle at the End of the Universe*
