Puzzling paradoxes that classical explanations fail to resolve, but are resolved by QM include: 1 Electrons don’t crash into protons. 2 Two slit pattern for individual particles 3 Entangled polarization issue as used by Bell 4 Larger particle spins also used by Bell 5 light stopped by H & V polar filters, by pass through H then Diag then V polar filters . . . (Or should 5 be considered part of 4) Are their any additional important paradoxes that it took QM to resolve??
