Human physical intuition is based on macroscopic physical phenomena as are experienced in everyday life, which can mostly be adequately described by the Newtonian mechanics of classical physics.[2] Early 20th-century models of atomic physics, such as the Rutherford–Bohr model, represented subatomic particles as little balls occupying well-defined spatial positions, but it was soon found that the physics needed at a subatomic scale, which became known as "quantum mechanics", implies many aspects for which the models of classical physics are inadequate.[3] These aspects include: [citation needed]
- quantum entanglement;[4][5]
- quantum nonlocality, referred to by Einstein as "spooky action at a distance";[4] see also EPR paradox;
- quantum superposition, presented in dramatic form in the thought experiment known as Schrödinger's cat;[5][6]
- the uncertainty principle;[4]
- wave–particle duality;[7]
- the probabilistic nature of wave function collapse, decried by Einstein, saying, "God does not play dice".[5]
