Jerzy Plebański
Jerzy Franciszek Plebański (7 May 1928, Warsaw – 24 August 2005, Mexico) was a Polish theoretical physicist best known for his extensive research into general relativity and supergravity. Biography In 1954, Plebański received his Ph.D. under the direction of Wojciech Rubinowicz at the University of Warsaw. He then went to work at the newly founded Institute of Theoretical Physics of the University of Warsaw. A specialist in the field of general relativity and mathematical physics, his first book with co-author Leopold Infeld was on the problem of motion in general relativity. He was Vice-Dean of the Faculty of Mathematics and Physics at the University of Warsaw from 1958 to 1962. In 1958 Plebański traveled to the United States, and spent two years there, first as an invited professor at the Institute for Advanced Study in Princeton, and then at UCLA in Los Angeles. The year after his return to Poland in 1960, he married Anna Lazarowicz. From 1962 to 1967 the Plebański ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Warsaw
Warsaw ( pl, Warszawa, ), officially the Capital City of Warsaw,, abbreviation: ''m.st. Warszawa'' is the capital and largest city of Poland. The metropolis stands on the River Vistula in east-central Poland, and its population is officially estimated at 1.86 million residents within a greater metropolitan area of 3.1 million residents, which makes Warsaw the 7th most-populous city in the European Union. The city area measures and comprises 18 districts, while the metropolitan area covers . Warsaw is an Alpha global city, a major cultural, political and economic hub, and the country's seat of government. Warsaw traces its origins to a small fishing town in Masovia. The city rose to prominence in the late 16th century, when Sigismund III decided to move the Polish capital and his royal court from Kraków. Warsaw served as the de facto capital of the Polish–Lithuanian Commonwealth until 1795, and subsequently as the seat of Napoleon's Duchy of Warsaw. Th ...

UCLA
The University of California, Los Angeles (UCLA) is a public land-grant research university in Los Angeles, California. UCLA's academic roots were established in 1881 as a teachers college then known as the southern branch of the California State Normal School (now San José State University). This school was absorbed with the official founding of UCLA as the Southern Branch of the University of California in 1919, making it the second-oldest of the 10-campus University of California system (after UC Berkeley). UCLA offers 337 undergraduate and graduate degree programs in a wide range of disciplines, enrolling about 31,600 undergraduate and 14,300 graduate and professional students. UCLA received 174,914 undergraduate applications for Fall 2022, including transfers, making the school the most applied-to university in the United States. The university is organized into the College of Letters and Science and 12 professional schools. Six of the schools offer undergraduate degre ...

American Mathematical Society
The American Mathematical Society (AMS) is an association of professional mathematicians dedicated to the interests of mathematical research and scholarship, and serves the national and international community through its publications, meetings, advocacy and other programs. The society is one of the four parts of the Joint Policy Board for Mathematics and a member of the Conference Board of the Mathematical Sciences. History The AMS was founded in 1888 as the New York Mathematical Society, the brainchild of Thomas Fiske, who was impressed by the London Mathematical Society on a visit to England. John Howard Van Amringe was the first president and Fiske became secretary. The society soon decided to publish a journal, but ran into some resistance, due to concerns about competing with the American Journal of Mathematics. The result was the ''Bulletin of the American Mathematical Society'', with Fiske as editor-in-chief. The de facto journal, as intended, was influential in in ...

Einstein–Infeld–Hoffmann Equations
The Einstein–Infeld–Hoffmann equations of motion, jointly derived by Albert Einstein, Leopold Infeld and Banesh Hoffmann, are the differential equations describing the approximate dynamics of a system of point-like masses due to their mutual gravitational interactions, including general relativistic effects. It uses a first-order post-Newtonian expansion and thus is valid in the limit where the velocities of the bodies are small compared to the speed of light and where the gravitational fields affecting them are correspondingly weak. Given a system of ''N'' bodies, labelled by indices ''A'' = 1, ..., ''N'', the barycentric acceleration vector of body ''A'' is given by: : \begin \vec_A & = \sum_ \frac \\ & \quad + \frac \sum_ \frac \left v_A^2+2v_B^2 - 4( \vec_A \cdot \vec_B) - \frac ( \vec_ \cdot \vec_B)^2 \right. \\ & \qquad \left. - 4 \sum_ \frac - \sum_ \frac + \frac( (\vec_B-\vec_A) \cdot \vec_B ) \right\\ & \quad ...

Arturo Rosenblueth
Arturo Rosenblueth Stearns (October 2, 1900 – September 20, 1970) was a Mexican researcher, physician and physiologist, who is known as one of the pioneers of cybernetics. Biography Rosenblueth was born in 1900 in Ciudad Guerrero, Chihuahua. He began his studies in Mexico City, then traveled to Berlin and Paris where he obtained his medical degree. Returning to Mexico City in 1927, he engaged in teaching and research in physiology. In 1930 he obtained a Guggenheim Scholarship and moved to Harvard University, to the department of Physiology, then directed by Walter Cannon. With Cannon he explored the chemical mediation of homeostasis. Rosenblueth cowrote research papers with both Cannon and Norbert Wiener, pioneer of cybernetics. Notably he was the lead author for the 1943 article 'Behavior, Purpose and Teleology' that was co-written by Wiener and Julian Bigelow and which was published in Philosophy of Science. Rosenblueth was an influential member of the core group at the Ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cold War
The Cold War is a term commonly used to refer to a period of geopolitical tension between the United States and the Soviet Union and their respective allies, the Western Bloc and the Eastern Bloc. The term '' cold war'' is used because there was no large-scale fighting directly between the two superpowers, but they each supported major regional conflicts known as proxy wars. The conflict was based around the ideological and geopolitical struggle for global influence by these two superpowers, following their temporary alliance and victory against Nazi Germany and Imperial Japan in 1945. Aside from the nuclear arsenal development and conventional military deployment, the struggle for dominance was expressed via indirect means such as psychological warfare, propaganda campaigns, espionage, far-reaching embargoes, rivalry at sports events, and technological competitions such as the Space Race. The Western Bloc was led by the United States as well as a number of other First W ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
