1900+to+1915

Werner Heisenberg (December 5, 1901 – February 1, 1976)

 Werner was a German Theoretical Physicist, who made great contributions to Quantum mechanics. Werner, Max Born, and Pascual Jordon, brought forth the Matrix formulation for quantum mechanics. This allowed Heisenberg to be awarded the Nobel prize in physics in 1932. He was best known for the uncertainty principle of quantum theory. He also made big contributions nuclear physics, and particle physics.

Quantam mechanics is the physics of the energy and how it acts in the atom. (1925) He said that it can only be changed by discrete amounts and when it is changed it is changed by that exact amount. The change does not vary it jumps from one number to the next.

Werner lived in Germany during the peak of Nazi rule. He spoke of many Jewish scientists and the SS tried to claim him a traitor. They branded him the "White Jew."

He died in Germany, and lived to be 74 years old. He died of kidney cancer.

Robert Millikan (March 22, 1868 – December 19, 1953)

 Millikan was and American experimental physicist. He was also a Nobel laureate in physics for his measurement of the charge on the electron, and work on the photoelectric effect. While a professor at the University of Chicago, he worked on the (1909) oil-drop experiment where he measured the charge of a single electron.  Ernest Rutherford (30 August 1871–19 October 1937)

Ernest was a British- New Zeland chemist and physicist who was known as the father of Nuclear Physics. In his early work he discovered the concept of radioactive half-life, which proved that radioactivity involved the mutation of one chemical element to another. He was awarded the Nobel prize in 1908 for the investigation of the desinigration of elements and the chemistry of radioactive materials.
