Werner Karl Heisenberg (5 December 1901 – 1 February 1976) was a German physicist. He won the Nobel Prize in Physics for his work in quantum mechanics. He discovered the Heisenberg uncertainty principle, which shows there is a limit on how well some things can be measured.
Heisenberg was a very good student and needed only three years to finish his studies. He then wrote a doctoral thesis about movements in the flows of liquids ("Über Stabilität und Turbulenz von Flüssigkeitsströmen"—"On the stability and turbulence of liquid streams"). In 1924 he became assistant to Max Born at the University of Göttingen and in 1926 worked with Niels Bohr at the University of Copenhagen.
Together with Born and Pascal Jordan he founded Quantum mechanics. At the age of 26 Heisenberg became professor of theoretical physics at the University of Leipzig. This was a very young age for such a job.
He was awarded the Nobel Prize when he was 31 years old.
During the Second World War, from 1942 to 1945 Werner Heisenberg was head of German atomic research work. This did not result in any working nuclear weapons, possibly because Heisenberg did not want it to. This is not a sure thing. Some people have said that Heisenberg was very much against the Nazis. Some people have said that he must have been for them, because he worked for them.
He died in Munich Germany, in 1976 at the age of 74.
