George Eugene Uhlenbeck (December 6, 1900 – October 31, 1988) was a Dutch-American theoretical physicist. ==Background and education== George Uhlenbeck was the son of Eugenius and Anne Beeger Uhlenbeck. He attended the Hogere Burgerschool (High School) in The Hague, from which he graduated in 1918. Subsequently entered Delft University of Technology as a student in chemical engineering. During the next year, he transferred to the Leiden University, to study physics and mathematics, and he earned his bachelor's degree in 1920. Uhlenbeck was then admitted by Ehrenfest (a student of Boltzmann's) to the Wednesday evening physics colloquium in Leiden. Ehrenfest became the most important scientific influence in his life. From 1922 to 1925 Uhlenbeck was the tutor of the younger son of the Dutch ambassador in Rome. While there, he attended lectures by Tullio Levi-Civita and Vito Volterra and met his longtime friend, Enrico Fermi. In 1923, Uhlenbeck received his master's degree from Leiden. He returned to Leiden in 1925 to become Ehrenfest's assistant. Ehrenfest assigned him to work with his graduate student, Samuel Goudsmit for a quick update on "what was currently happening in physics". In mid-September 1925, Uhlenbeck and Goudsmit discovered the spin on the electron. In 1927 Uhlenbeck earned his Ph.D. degree under Ehrenfest with his thesis titled: "Over Statistische Methoden in de Theorie der Quanta" ("On Statistical Methods in the Quantum Theory" ). Uhlenbeck married Else Ophorst in Arnhem, Netherlands in August 1927. He received a doctorate from the Leiden University in the same year. As a graduate student in 1925, he and Samuel Goudsmit introduced the concept of electron spin, which posits an intrinsic angular momentum for all electrons. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「George Uhlenbeck」の詳細全文を読む スポンサード リンク
