Yes, he was an Epsteinite, but his point was generally correct. Einstein, Schrödinger, and Bell all recognized that the orthodox interpretation of quantum mechanics makes no sense because it postulates a transition from quantum to classical with no explanation of how this actually occurs. They would not have liked Many Worlds either because it does not actually get rid of the transition, it just claims the classical world is an illusion so it shifts the transition to something happening in your brain, but then doesn’t explain how your brain could possibly create a world of discrete events happening in 3D space from a world where no discrete events ever happen that is just one giant continuous wave evolving in an infinite-dimensional space as there is no clear way to map the latter onto the former. Bell was around when Many Worlds was becoming popularized and so he did comment on it and pointed out it is nonsense and Everett never demonstrated any way to carry out this mapping consistently.

Don’t forget his contribution to paedomechanics.

real dragons? 🤔
