## Speakable and Unspeakable in Quantum Mechanics: Collected Papers on Quantum PhilosophyThis book comprises all of John Bell's published and unpublished papers in the field of quantum mechanics, including two papers that appeared after the first edition was published. It also contains a preface written for the first edition, and an introduction by Alain Aspect that puts into context Bell's great contribution to the quantum philosophy debate. One of the leading expositors and interpreters of modern quantum theory, John Bell played a major role in the development of our current understanding of the profound nature of quantum concepts. First edition Hb (1987): 0-521-33495-0 First edition Pb (1988): 0-521-36869-3 |

### What people are saying - Write a review

This book includes the papers and ideas which have put the cat among the pigeons in modern science: Bell has simply stuck us with the fact that we know the ideas upon which we reliably base something like 40% of our economy are wrong.

We know they're wrong, and we operate on one version of them, the "Copenhagen interpretation," knowing that it's just as wrong as all the other versions, but easier to live with. Some time in the next 40 or 50 years we shall probably come to either a better understanding of how the world works, or of how our minds work, or maybe of how our understanding of how the world works works.

This is where that quest started.

J.S. Bell is a fine writer, a clean expositor, and a witty man. The book is a pleasure.

That's a good thing, because you'll have to read it several times. At least I shall.
