## A short Summary about the History of Theoretical Physics in Göttingen |

Already since 1849 both of the full chairs of the physics department in Göttingen (Weber, Listing) have been corresponding with nearly the division into experimental and theoretical physics.

Max Born (ca. 1925) |

Werner Heisenberg (ca. 1926) |

Heisenberg concluded from the observable energy spectrum of atoms a mathematical formalism which allowed to calculate observable quantities like frequency, intensity and polarisation of radiation without any reverting to a model. Born saw the underlying mathematical structure (matrixes, operators) and refined them to the quantum mechanics together with his younger colleagues Heisenberg and Jordan.

At the same time Schrödinger evolved the so-called wave mechanics, which should describe waves of matter according to the theory of von de Broglie.

However, Born showed, that Schrödinger's wave function is combined with a probability interpretation, which explains the probability of staying for the position of the particle. Born's probability interpretation and Heisenberg's uncertainty relation changed our understanding of nature in a revolutionary way.

Max Born as well as Werner Heisenberg were awarded with the Nobel prize (1954 or 1932).

With the seizure of power of the National Socialists this heyday came to an abrupt end. R. Becker (in Göttingen 1936 - 1955) and F. Hund tried successfully that the institute gained importance again.

In the meantime it was clear that the basic research of the twenties was used for life-exterminational measures in form of nuclear weapons. So 1957 prominent German scientists, among these apart from Otto Hahn, Max von Laue and Carl-Friedrich von Weizäcker also the "old" Göttinger Max Born and Werner Heisenberg, joined to the "Göttinger Declaration" against the nuclear arming of the Federal Armed Forces and against the global nuclear armaments.
