Prof. Harvey Brown: The evolution of Bell's thinking about the Bell theorem

Slides: https://drive.google.com/file/d/1lqOr... --------- Abstract The 1964 Bell nonlocality theorem did much to expand the foundations of quantum mechanics from philosophy seminars into mainstream physics. In this talk I will concentrate on how the theorem was conceived, and how later variations of the theorem led Bell to a wider notion of nonlocality, and a change in the significance of the theorem. I will also discuss whether Bell thought nonlocality is consistent or otherwise with special relativity, and address the wider question as to whether the Bell theorem, in any of its variants, shows that quantum mechanics is necessarily nonlocal, as is often claimed. (The talk will be for non-experts, but based on my paper with Christopher Timpson: "Bell on Bell's theorem: The changing face of nonlocality", in Quantum Nonlocality and Reality, Mary Bell and Shan Gao (eds.), Cambridge University Press, 2016, pp. 91-123. http://arxiv.org/abs/1501.03521) --------- Speaker Information Harvey Brown is a Professor of Philosophy of Physics at Oxford University, and a fellow of the British Academy. He studied physics at the University of Cantebury in New Zealand, and then pursued graduate studies in philosophy at Chelsea College in London. Prior to moving to Oxford he taught at the University of Sao Paulo in Brazil. Professor Brown has written on varied topics in the philosophy of physics, including 4 books on on topics including the philosophy of quantum field theory and on spacetime. His present research interests include the foundations of quantum mechanics, relativity theory and thermal physics, the philosophy of space and time, and the role of symmetry principles in physics. --------- CUPS - Cambridge University Physics Society We are a student-run university society organising scientific talks and other events for our members and public.
