Quantum Theory Cannot Hurt You The two towering achievements of modern physics are quantum theory and Einstein’s general theory of relativity. Together, they explain virtually everything about the world we live in. But, almost a century after their advent, most people haven’t the slightest clue what either is about.

In simple language, in a book that can be read in a morning, he illuminates the two most brilliant and exhilarating ideas of the last century.
