# The least physics you need is a lot in ‘Quantum Mechanics'

## Leonard Susskind and Art Friedman offer the theoretical minimum you need to know to start doing physics

*Quantum Mechanics: The Theoretical Minimum*

Leonard Susskind and Art Friedman

Basic Books, $26.99

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.

Susskind’s latest book, this one with coauthor Friedman, is the second in a series on the “theoretical minimum” you’d need to know to actually be able to do physics. The first focused on the basics of classical physics. This one takes you deep into the weird realm of quantum theory.

There’s no popularization here. Just clear, straightforward exposition of basic quantum principles and their mystifying implications. Susskind starts with qubits, the quantum units of information
