Quantum mechanics
Quantum mechanics is a branch of physics that describes microscopic matter, which, together with relativity, is considered to be the two basic pillars of modern physics, and many physical theories and sciences, such as atomic physics, solid state physics, nuclear physics, and particle physics As well as other related disciplines, are based on it. At the end of the 19th century, the shortcomings and contradictions of classical mechanics and classical electrodynamics in describing microcosmic systems became more and more obvious. Quantum mechanics was at the beginning of the twentieth century by Max Planck, Nils Bohr, Werner Heisenberg, Elwin Schrodinger, Wolfgang Pauli, Louis de Broglie, Max Born, Enrico Fermi, Paul Dirac, Albert Einstein and other large group of physicists co-founded. Through quantum mechanics, people's views on the structure of matter and its interaction are fundamentally changed, and many phenomena can be truly explained. By quantum mechanics, the classical theory can not be directly predicted by the phenomenon, can now be accurately calculated, and in the subsequent experiments can be verified. In addition to the gravitational depiction described by general relativity, all other physical fundamental interactions so far can be described in the framework of quantum mechanics (quantum field theory). ...
