Bell Theorem naive view 18 Alain Aspect BELL'S THEOREM : THE NAIVE VIEW OF AN EXPERIMENTALIST† Alain Aspect Institut d'Optique Théorique et Appliquée Bâtiment 503-Centre universitaire d'Orsay 91403 ORSAY Cedex – France 1. INTRODUCTION It is a real emotion to participate to this conference in commemoration of John Bell. I first met him in 1975, a few months after reading his famous paper1. I had been so strongly impressed by this paper, that I had immediately decided to do my « thèse d'état » – which at that time, in France, could be a really long work – on this fascinating problem. I definitely wanted to carry out an experiment « in which the settings are changed during the flight of the particles », as suggested in the paper, and I had convinced a young professor of the Institut d'Optique, Christian Imbert, to support my project and to act as my thesis advisor. But he had advised me to first go to Geneva, and to discuss my proposal with John Bell. I got an appointment without delay, and I showed up in John's office at CERN, very impressed. While I was explaining my planned experiment, he silently listened. Eventually, I stopped talking, and the first question came: “Have you a permanent position?” After my positive answer, he started talking of physics, and he definitely encouraged me, making it clear that he would consider the implementation of variable analysers a fundamental improvement.
