Heisenberg, (-)

Werner Heisenberg (1901-1975), 1932 Nobel Prize-winner in physics, developed a theory of matrix mechanics around 1925. This concerned the mathematical formulation based on the frequencies and amplitudes of the radiations absorbed and emitted by the atom and on the energy levels of the atomic system. His uncertainly pinciple effected the development of quantum mechanics and of modern philosophical thinking.
