Irene Fischer
Irene Kaminka Fischer (born July 27, 1907 in Vienna, Austria, died October 22, 2009 in Boston) was an Austrian-American mathematician and geodesist. She was a member of the National Academy of Engineering, a Fellow of the American Geophysical Union, and inductee of the National Imagery and Mapping Agency Hall of Fame. Fischer became one of two internationally known women scientists in the field of geodesy during the golden age of the Project Mercury and the Apollo program. Her ''Mercury datum'' (or ''Fischer ellipsoid'' 1960 and 1968), as well as her work on the lunar parallax, were instrumental in conducting these missions. "In his preface to the ACSM publication, Fischer's former colleague, Bernard Chovitz, referred to her as one of the most renowned geodesists of the third quarter of the twentieth century. Yet this fact alone makes her one of the most renowned geodesists of all times, because, according to Chovitz, the third quarter of the twentieth century witness ...

Lunar Parallax
The most important fundamental distance measurements in astronomy come from trigonometric parallax. As the Earth orbits the Sun, the position of nearby stars will appear to shift slightly against the more distant background. These shifts are angles in an isosceles triangle, with 2 AU (the distance between the extreme positions of Earth's orbit around the Sun) making the base leg of the triangle and the distance to the star being the long equal length legs. The amount of shift is quite small, even for the nearest stars, measuring 1 arcsecond for an object at 1 parsec's distance (3.26 light-years), and thereafter decreasing in angular amount as the distance increases. Astronomers usually express distances in units of parsecs (parallax arcseconds); light-years are used in popular media. Because parallax becomes smaller for a greater stellar distance, useful distances can be measured only for stars which are near enough to have a parallax larger than a few times the precision ...

Maimonides Institute
Musa ibn Maimon (1138–1204), commonly known as Maimonides (); la, Moses Maimonides and also referred to by the acronym Rambam ( he, רמב״ם), was a Sephardic Jewish philosopher who became one of the most prolific and influential Torah scholars of the Middle Ages. In his time, he was also a preeminent astronomer and physician, serving as the personal physician of Saladin. Born in Córdoba, Almoravid Empire (present-day Spain), on Passover eve, 1138 (or 1135), he worked as a rabbi, physician and philosopher in Morocco and Egypt. He died in Egypt on 12 December 1204, when his body was taken to the lower Galilee and buried in Tiberias. During his lifetime, most Jews greeted Maimonides' writings on Jewish law and ethics with acclaim and gratitude, even as far away as Iraq and Yemen. Yet, while Maimonides rose to become the revered head of the Jewish community in Egypt, his writings also had vociferous critics, particularly in Spain. Nonetheless, he was posthumously acknowle ...

Paul Lazarsfeld
Paul Felix Lazarsfeld (February 13, 1901August 30, 1976) was an Austrian-American sociologist. The founder of Columbia University's Bureau of Applied Social Research, he exerted influence over the techniques and the organization of social research. "It is not so much that he was an American sociologist," one colleague said of him after his death, "as it was that he determined what American sociology would be." Lazarsfeld said that his goal was "to produce Paul Lazarsfelds". The two main accomplishments he is associated with can be analyzed within two lenses of analysis: research institutes, methodology, as well as his research content itself. He was a founding figure in 20th-century empirical sociology. Austria Lazarsfeld was born to Jewish parents in Vienna: his mother was the Adlerian therapist Sophie Lazarsfeld, and his father Robert was a lawyer. He attended schools in Vienna, eventually receiving a doctorate in mathematics (his doctoral dissertation dealt with mathematica ...

Victor Weisskopf
Victor Frederick "Viki" Weisskopf (also spelled Viktor; September 19, 1908 – April 22, 2002) was an Austrian-born American theoretical physicist. He did postdoctoral work with Werner Heisenberg, Erwin Schrödinger, Wolfgang Pauli, and Niels Bohr. During World War II he was Group Leader of the Theoretical Division of the Manhattan Project at Los Alamos, and he later campaigned against the proliferation of nuclear weapons. Biography Weisskopf was born in Vienna to Jewish parents and earned his doctorate in physics at the University of Göttingen in Germany in 1931. His brilliance in physics led to work with the great physicists exploring the atom, especially Niels Bohr, who mentored Weisskopf at his institute in Copenhagen. By the late 1930s, he realized that, as a Jew, he needed to get out of Europe. Bohr helped him find a position in the United States. In the 1930s and 1940s, "Viki", as everyone called him, made major contributions to the development of quantum theory, esp ...

Vienna Circle
The Vienna Circle (german: Wiener Kreis) of Logical Empiricism was a group of elite philosophers and scientists drawn from the natural and social sciences, logic and mathematics who met regularly from 1924 to 1936 at the University of Vienna, chaired by Moritz Schlick. The Vienna Circle's influence on 20th-century philosophy, especially philosophy of science and analytic philosophy, is immense up to the present day. The philosophical position of the Vienna Circle was called logical empiricism (German: ''logischer Empirismus''), logical positivism or neopositivism. It was influenced by Ernst Mach, David Hilbert, French conventionalism ( Henri Poincaré and Pierre Duhem), Gottlob Frege, Bertrand Russell, Ludwig Wittgenstein and Albert Einstein. The Vienna Circle was pluralistic and committed to the ideals of the Enlightenment. It was unified by the aim of making philosophy scientific with the help of modern logic. Main topics were foundational debates in the natural and social s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hans Hahn (mathematician)
Hans Hahn (; 27 September 1879 – 24 July 1934) was an Austrian mathematician and philosopher who made contributions to functional analysis, topology, set theory, the calculus of variations, real analysis, and order theory. In philosophy he was among the main logical positivists of the Vienna Circle. Biography Born in Vienna as the son of a higher government official of the k.k. Telegraphen-Korrespondenz Bureau (since 1946 named "Austria Presse Agentur"), in 1898 Hahn became a student at the Universität Wien starting with a study of law.

Moritz Schlick
Friedrich Albert Moritz Schlick (; ; 14 April 1882 – 22 June 1936) was a German philosopher, physicist, and the founding father of logical positivism and the Vienna Circle. Early life and works Schlick was born in Berlin to a wealthy Prussian family with deep nationalist and conservative traditions. His father was Ernst Albert Schlick and his mother was Agnes Arndt. At the age of sixteen, he started to read Descartes' ''Meditations'' and Schopenhauer's ''Die beiden Grundprobleme der Ethik''. Nietzsche's ''Also sprach Zarathustra'' especially impressed him. He studied physics at the University of Heidelberg, the University of Lausanne, and, ultimately, the University of Berlin under Max Planck. Schlick explained this choice in his autobiography by saying that, despite his love for philosophy, he believed that only mathematical physics could help him obtain actual and exact knowledge. He felt deep distrust towards any metaphysical speculation. In 1904, he completed his PhD the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
