was a theoretical physicist. He studied various topics, such as the time reversal of quantum mechanics, pattern recognition, cognitive science, and the concept of time. He was the first physicist to show clearly that quantum probability theory is time-asymmetric (irreversible; non-invariant under time reversal), and reject the conventional analysis of the time reversal of probability laws. He developed the Double Inferential Vector Formalism (DIVF), later known as the Two-state vector formalism (TSVF), which is sometime interpreted as contradicting his proof of time-asymmetry, but this is a misunderstanding. He also proposed the Ugly duckling theorem. == Early life and education == Satosi Watanabe was born on May 26, 1910, in Tokyo. He attended Gakushuuin Middle High School and Tokyo High School. In 1933, he graduated from Tokyo Imperial University in theoretical physics, where Torahiko Terada was his teacher. The imperial government sent him to France to study. Louis de Broglie encouraged Watanabe to study thermodynamics and wave mechanics. In 1937, he moved to Leipzig and started to study nuclear theory under Heisenberg. In the same year, Watanabe married Dorothea Dauer, a scholar of German literature. In 1939, at the beginning of World War II, he left Germany and stayed with Niels Bohr for a time. In December, he returned to Japan with his family. 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「Satosi Watanabe」の詳細全文を読む スポンサード リンク
