'I was not a particularly small child. I was the one who always got picked to play Bethlehem in the school nativity.'

George Eugene UhlenbeckBorn 6 Dec 1900; died 31 Oct 1988 at age 87. Dutch-American physicist who, with Samuel A. Goudsmit, proposed the concept of electron spin (Jan 1925) - a fourth quantum number which was a half integer. This provided Wolfgang Pauli's anticipated “fourth quantum number.” In their experiment, a horizontal beam of silver atoms travelling through a vertical magnetic field was deflected in two directions according to the interaction of their spin (either “up” or “down”) with the magnetic field. This was the first demonstration of this quantum effect, and an early confirmation of quantum theory. As well as fundamental work on quantum mechanics, Uhlenbeck worked on atomic structure, the kinetic theory of matter and extended Boltzmann's equation to dense gases.« |
