### 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.

John Bell, FRS was one of the leading expositors and interpreters of modern quantum theory. He is particularly famous for his discovery of the crucial difference between the predictions of conventional quantum mechanics and the implications of local causality, a concept insisted on by Einstein. John Bell's work played a major role in the development of our current understanding of the profound nature of quantum concepts and of the fundamental limitations they impose on the applicability of the classical ideas of space, time and locality. This book includes all of John Bell's published and unpublished papers on the conceptual and…
