The truth about reality

摘要

Hopes of keeping quantum mechanics 'real' have been dashed by new measurements of neutrons' quantum behaviour. Despite what our classical sensibilities require, the world is indeed fundamentally random. Albert Einstein was convinced that "God does not play dice"; in other words, he could not accept quantum theory, with its inherent randomness, as a fundamental description of the world. Developing the theme in later work with Boris Podolsky and Nathan Rosen, he hinted that he believed in a more basic layer of truth underlying quantum mechanics.
