*Through no art of interpretation can this psi-function be turned into an adequate description of a real state of affairs; in reality there is no intermediary between exploded and not-exploded.'* This is interesting. Einstein (but other physicists too) avoiding retrocausality and stochasticity, like vampires avoiding sunlight and running water. :) -pt -- You received this message because you are subscribed to the Google Groups "Everything List" group.
