Quantum and classical mechanics are derived using four natural physicalprinciples: (1) the laws of nature are invariant under time evolution, (2) thelaws of nature are invariant under tensor composition, (3) the laws of natureare relational, and (4) positivity (the ability to define a physical state).Quantum mechanics is singled out by a fifth experimentally justified postulate:nature violates Bell's inequalities.
