It also explains our ability to make measurements and record results. To claim that this is not a fundamental account of measurement is just silly. Nothing is more fundamental than quantum entanglement evidenced in decoherence. Bruce -- You received this message because you are subscribed to the Google Groups "Everything List" group.
