1901 – Born on the 5th of December.
1925 – He invented matrix mechanics, the first formalization of quantum mechanics.
1927 – His uncertainty principle, developed, states that the simultaneous determination of two paired quantities, for example the position and momentum of a particle, has an unavoidable uncertainty.
1932 – He received the Nobel Prize in physics.
1938 – Nuclear fission was discovered in Germany.
1941 – Heisenberg would report to Bohr that his research efforts had led him to conclude that a usable nuclear weapon was feasible if, in fact, a miscalculation had led him to conclude that it was not feasible.
1942 – On the 4th of June, Heisenberg met with German Minister Albert Speer concerning possible uses of Heisenberg’s nuclear research, and particularly its potential suitability for the development of nuclear weapons.
1976 – Died on the 1st of February.
