International Encyclopedia Of Unified Science
The ''International Encyclopedia of Unified Science'' (''IEUS'') was a series of publications devoted to unified science. The IEUS was conceived at the Mundaneum Institute in The Hague in the 1930s, and published in the United States beginning in 1938. It was an ambitious project that was never completed. The IEUS was an output of the Vienna Circle to address the "growing concern throughout the world for the logic, the history, and the sociology of science..." Only the first section ''Foundations of the Unity of Science'' (FUS) was published; it contains two volumes for a total of nineteen monographs published from 1938 to 1969. International Congresses for the Unity of Science Creation of the IEUS was facilitated by the International Congresses for the Unity of Science organized by members of the Vienna Circle. After a preliminary conference in Prague in 1934, the First International Congress for the Unity of Science was held at the Sorbonne, Paris, 16–21 September 1935. I ...

Federigo Enriques
Abramo Giulio Umberto Federigo Enriques (5 January 1871 – 14 June 1946) was an Italian mathematician, now known principally as the first to give a classification of algebraic surfaces in birational geometry, and other contributions in algebraic geometry. Biography Enriques was born in Livorno, and brought up in Pisa, in a Sephardi Jewish family of Portuguese descent. His younger brother was zoologist Paolo Enriques who was also the father of Enzo Enriques Agnoletti and Anna Maria Enriques Agnoletti.

Philipp Frank (; March 20, 1884 – July 21, 1966) was an Austrian-American physicist, mathematician and philosopher of the early-to-mid 20th century. He was a logical positivist, and a member of the Vienna Circle. He was influenced by Mach and was one of the Machists criticised by Lenin in ''Materialism and Empirio-criticism''. Biography He studied physics at the University of Vienna and graduated in 1907 with a thesis in theoretical physics under the supervision of Ludwig Boltzmann. He joined the faculty there in 1910. Albert Einstein recommended him as his successor for a professorship at the German Charles-Ferdinand University of Prague, a position which he held from 1912 until 1938.

Morris Raphael Cohen
Morris Raphael Cohen (; July 25, 1880 – January 28, 1947) was a Russian-born American judicial philosopher, lawyer, and legal scholar who united pragmatism with logical positivism and linguistic analysis. This union coalesced into the "objective relativism" fermenting at Columbia University before and during the early twentieth-century interwar period. He was father to Felix S. Cohen and Leonora Cohen Rosenfield. Life and career Cohen was born in Minsk, Imperial Russia (present-day Belarus), the son of Bessie (Farfel) and Abraham Mordecai Cohen.

Élie Cartan
Élie Joseph Cartan (; 9 April 1869 – 6 May 1951) was an influential French mathematician who did fundamental work in the theory of Lie groups, differential systems (coordinate-free geometric formulation of PDEs), and differential geometry. He also made significant contributions to general relativity and indirectly to quantum mechanics. He is widely regarded as one of the greatest mathematicians of the twentieth century. His son Henri Cartan was an influential mathematician working in algebraic topology. Life Élie Cartan was born 9 April 1869 in the village of Dolomieu, Isère to Joseph Cartan (1837–1917) and Anne Cottaz (1841–1927). Joseph Cartan was the village blacksmith; Élie Cartan recalled that his childhood had passed under "blows of the anvil, which started every morning from dawn", and that "his mother, during those rare minutes when she was free from taking care of the children and the house, was working with a spinning-wheel".

Rudolf Carnap
Rudolf Carnap (; ; 18 May 1891 – 14 September 1970) was a German-language philosopher who was active in Europe before 1935 and in the United States thereafter. He was a major member of the Vienna Circle and an advocate of logical positivism. Biography Carnap's father rose from being a poor ribbon-weaver to be the owner of a ribbon-making factory.

Niels Bohr
Niels Henrik David Bohr (, ; ; 7 October 1885 – 18 November 1962) was a Danish theoretical physicist who made foundational contributions to understanding atomic structure and old quantum theory, quantum theory, for which he received the Nobel Prize in Physics in 1922. Bohr was also a philosopher and a promoter of scientific research. Bohr developed the Bohr model of the atom, in which he proposed that energy levels of electrons are discrete and that the electrons revolve in stable orbits around the atomic nucleus but can jump from one energy level (or orbit) to another. Although the Bohr model has been supplanted by other models, its underlying principles remain valid. He conceived the principle of Complementarity (physics), complementarity: that items could be separately analysed in terms of contradictory properties, like behaving as a Wave–particle duality, wave or a stream of particles. The notion of complementarity dominated Bohr's thinking in both science and philoso ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
