He was the father of the neurobiologist Martin Heisenberg and the son of August Heisenberg. Werner Karl Heisenberg (German: [ËhaÉªzÉnbÉÉÌ¯k]; 5 December 1901 â 1 February 1976) was a German theoretical physicist and one of the key pioneers of quantum mechanics. He published his work in 1925 in a breakthrough paper.
The theory provided a good description of the spectrum created by the hydrogen atom, but needed to be developed to suit more complicated atoms and molecules. In 1925, Werner Heisenberg formulated a type of quantum mechanics based on matrices. In 1927 he proposed the uncertainty relation, setting limits for how precisely the position and velocity of a particle can be simultaneously determined.
