19 応用エネルギーのミーゼス♪

1883年4月19日は、科学者ミーゼスの生まれた日♪

リヒャルト・フォン・ミーゼスは、ウィーン工科大学で学び、1907年に博士号を得、1919年にベルリン大学に採用され、応用数学の雑誌を創刊した♪　著名な業績としてはひずみエネルギー説がある。塑性設計に用いられるミーゼス応力、ミーゼスの降伏条件式は、この理論に基づいている。

1933年にナチスが政権を獲得すると、ミーゼス自身はカトリック教徒だったが先祖にユダヤ人が居たため、「非アーリア人」に分類されてしまった。そのため、1939年にアメリカ合衆国に亡命してハーバード大学の教授に就任した。

1943年に、ベルリン脱出から逃避行をともにしてきた数学者のヒルダ・ガイリンガーと結婚。生涯を通して、流体力学、空気力学、航空工学、静力学および確率論に業績を残した♪

Richard Edler von Mises (19 April 1883 – 14 July 1953) was a scientist and mathematician who worked on solid mechanics, fluid mechanics, aerodynamics, aeronautics, statistics and probability theory. He held the position of Gordon-McKay Professor of Aerodynamics and Applied Mathematics at Harvard University. He described his work in his own words shortly before his death as being on

"... practical analysis, integral and differential equations, mechanics, hydrodynamics and aerodynamics, constructive geometry, probability calculus, statistics and philosophy."
Although best known for his mathematical work, Mises also contributed to the philosophy of science as a neo-positivist, following the line of Ernst Mach. Historians of the Vienna Circle of logical empiricism recognize a "first phase" from 1907 through 1914 with Philipp Frank, Hans Hahn, and Otto Neurath.[citation needed] His older brother, Ludwig von Mises, held an opposite point of view with respect to positivism and epistemology.

During his time in Istanbul, Mises maintained close contact with Philipp Frank, a logical positivist and Professor of Physics in Prague until 1938. His literary interests included the Austrian novelist Robert Musil and the poet Rainer Maria Rilke, on whom he became a recognized expert.
