Jordan, Ernst Pascual (1902-1980), was a German physicist. He helped develop quantum mechanics, a field of physics that describes the structure of atoms and the motion of atomic particles.
In 1925, Jordan helped two other German physicists, Max Born and Werner Heisenberg, write the first mathematical formulation of quantum mechanics. By 1928, Jordan developed second quantization, a method of analyzing interactions between many atomic particles or waves. He also contributed to the knowledge of the subatomic particles called neutrinos, to the theory of gravitation, and to the philosophy of physics. Jordan was born on Oct. 18, 1902, in Hanover, Germany. He died on July 31, 1980.
