Quantum mechanics as well as quantum field theory, is a division of physics which is an essential concept of nature at the minimum scales of energy levels of subatomic particles and atoms. Classical physics originates from quantum mechanics as a calculation, valid only at macroscopic scales. Quantum mechanics varies from classical physics in that momentum, energy and other quantities are often limited to discrete values i.e. quantization, objects have characteristics of both waves and particles and there are limits to the precision with which quantities can be known. Forecasts of quantum mechanics have been tested experimentally to an extremely high degree of accuracy. As per the correspondence theory between quantum mechanics and classical mechanics, all objects follow the laws of quantum mechanics. Classical mechanics is just an approximation for large systems of objects. The laws of classical mechanics thus follow from the laws of quantum mechanics as a statistical average at the limit of large systems or large quantum numbers.
