Why did I love this book?
John Bell’s theorem about the unavoidability of what Einstein called “spooky action-at-a-distance” in quantum mechanics set off the second quantum revolution, leading to quantum computation, quantum cryptography, and quantum teleportation among other insights. This book collects Bell’s most important papers which range in style from professionally mathematical to popular and intuitive, so there is something for everyone. Beginners can start with “Quantum Mechanics for Cosmologists” or “Six Possible Worlds of Quantum Mechanics” or “Bertlmann’s Socks and the Nature of Reality” or “La Nouvelle Cuisine”. Experts can learn from “Against ‘Measurement’”. People interested in the mathematical details can find them, and people scared by math can largely avoid them.
