Auszug aus Wikipedia: Werner Heisenberg (5 December 1901 - 1 February 1976) was a German physicist who made foundational contributions to quantum mechanics and is best known for asserting the uncertainty principle (Heisenbergsche Unschärferelation), of quantum theory. Heisenberg was awarded the 1932 Nobel Prize in Physics for the creation of quantum mechanics, and its application especially to the discovery of the allotropic forms of hydrogen. In 1957, Heisenberg was a signatory of the manifesto of the Göttinger Achtzehn (Göttingen Eighteen). Clip based on public domain photo from Wikipedia.
