I’ve been meaning to do some new digging on Einstein’s enigmatic complaint. In a recent program on Channel 13 (I think, but I can’t locate it now) a recognized physicist portrayed Einstein as unable to accept uncertainty in nature, and that view seems to be becoming one of the prevalent understandings of the issue (see Wiki link below). On the face of it, since Einstein was a founder of statistical physics, it seems unlikely. “God doesn’t roll dice”, is about something else. One of the things I finally found today to expose the deeper issue was Niels Bohr’s long, polite, emphatic last-word on the subject (Bohr 1949). Bohr says that what Einstein objected to in QM was the elimination of causality and continuity.
“Yet, a certain difference in attitude and outlook remained, since, with his mastery for coordinating apparently contrasting experience without abandoning continuity and causality, Einstein was perhaps more reluctant to renounce such ideals than someone for whom renunciation in this respect appeared to be the only way open to proceed with the immediate task.”
