I read the first time, this book by Professor Nicolas Gisin. I enjoyed but to better understand I will soon read as the author advises me. I do not know much about quantum physics if not that the assiduous reading of "Science and Life" allows me to understand. The preface, signed by Professor Alain Aspect I do not know but in the village where I lived for almost 34 years is also very interesting. General de Gaulle said (it seems): "Researchers you have, one looks in finders". Nicolas Gisin and Alain Aspect, you'll understand that part of the race of finders. "The unthinkable accident," a book that I recommend to all those seeking to learn more and more.
