What is Quantum Mechanics?

Quantum mechanics (QM; also known as quantum physics or quantum theory), including quantum field theory, is a branch of physics which is the fundamental theory of nature at the small scales and energy levels of atoms and subatomic particles.

Classical physics (the physics existing before quantum mechanics) derives from quantum mechanics as an approximation valid only at large (macroscopic scales. Quantum mechanics differs from classical physics in that: energymomentum and other quantities are often restricted to discrete values (quantization), objects have characteristics of both particles and waves (i.e. wave-particle duality), and there are limits to the precision with which quantities can be known (uncertainty principle).

Quantum mechanics gradually arose from Max Planck's solution in 1900 to the black-body radiation problem, and Albert Einstein's 1905 paper which offered a quantum-based theory to explain the photoelectric effectEarly quantum theory was profoundly re-conceived in the mid-1920s by Erwin SchrodingerWerner HeisenbergMax Born and others. The modern theory is formulated in various specially developed mathematical formalisms. In one of them, a mathematical function, the wave function, provides information about the probability amplitude of position, momentum, and other physical properties of a particle.

Important applications of quantum theory include quantum chemistrysuperconducting magnetslight-emitting diodes, and the laser, the transistor and semiconductors such as the microprocessormedical and research imaging such as magnetic resonance imaging and electron microscopy. Explanations for many biological and physical phenomena are rooted in the nature of the chemical bond, most notably the macro-molecule DNA.
