Quantum Mechanics

Peter Woit, 2006, Not Even Wrong, The failure of String Theory and the Search for Unity in Physical Law

After the Elegant Universe I have started Not Even Wrong by Peter Woit to see what opponents of the superstring theory say.  In the Preface, there is a nice statement about quantum mechanics, p. xvi

Part of the appeal of quantum mechanics to me was its peculiar character of being a kind of esoteric practice. Through long study and deep thought, one could hope to arrive at an understanding of the hidden nature of the universe. Unlike other popular exotic religions or mind-altering activities of the time, this sort of search for enlightenment appeared to be both much more solid and something for which I actually had some talent.
