You Will Not Read Anything Deeper in ‘Science’: On The Philosophy, History and Mathematics Behind the Physics of John Bell’s Universe

You Will Not Read Anything Deeper in ‘Science’: On The Philosophy, History and Mathematics Behind the Physics of John ‘Bell’s Universe: “No one has messed with our heads more than John Bell” ~ Andrew Friedman! Reinhold A. Bertlmann: My collaboration and friendship with John Bell is recollected. I will explain his outstanding contributions in particle physics, in accelerator physics, and his joint work with Mary Bell. Mary’s work in accelerator physics is also summarized. I recall our quantum debates, mention some personal reminiscences, and give my personal view on Bell’s fundamental work on quantum theory, in particular, on the concept of contextuality and nonlocality of quantum physics. Finally, I describe the huge influence Bell had on my own work, in particular on entanglement and Bell inequalities in particle physics and their experimental verification, and on mathematical physics, where some geometric aspects of the quantum states are illustrated.
