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.
At the same time that the wave properties of matter were discovered, two further discoveries were made by Werner Heisenberg and Max Born that also profoundly influenced (and confused) the future evolution of modern physics and quantum mechanics; Werner Heisenberg developed the uncertainty principle which tells us that we (the observer) can never exactly know both the position and momentum of a particle. As every observation requires an energy exchange (photon) to create the observed 'data', some energy (wave) state of the observed object has to be altered.
