Alfred Schild
Alfred Schild (September 7, 1921 – May 24, 1977) was a leading Austrian American physicist, well known for his contributions to the Golden age of general relativity (1960–1975). Biography Schild was born in Istanbul on September 7, 1921. His parents were German-speaking Viennese Jews, but his early education was in England. Upon the outbreak of World War II Schild was interned as an enemy alien, but later allowed to travel to Canada. In 1944 he earned his B.A. at the University of Toronto, and in 1946 completed his doctorate under the direction of Leopold Infeld. Schild spent the next eleven years at the Carnegie Institute of Technology, where he helped to develop the first atomic clocks. As tensors are the language of general relativity, Schild wrote ''Tensor Calculus'' with John L. Synge as a textbook. According to a reviewer, "The ideas and concepts are given very concisely and thus a wide range of subjects is considered." In 1957 he moved to the University of Te ...

Atomic Clock
An atomic clock is a clock that measures time by monitoring the resonant frequency of atoms. It is based on atoms having different energy levels. Electron states in an atom are associated with different energy levels, and in transitions between such states they interact with a very specific frequency of electromagnetic radiation. This phenomenon serves as the basis for the International System of Units' (SI) definition of a second:The second, symbol s, is the SI unit of time. It is defined by taking the fixed numerical value of the caesium frequency, \Delta \nu_\mathsf, the unperturbed ground-state hyperfine transition frequency of the caesium 133 atom, to be when expressed in the unit Hz, which is equal to s−1. This definition is the basis for the system of International Atomic Time (TAI), which is maintained by an ensemble of atomic clocks around the world. The system of Coordinated Universal Time (UTC) that is the basis of civil time implements leap seconds to allo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Roy Kerr
Roy Patrick Kerr (; born 16 May 1934) is a New Zealand mathematician who discovered the Kerr geometry, an exact solution to the Einstein field equation of general relativity. His solution models the gravitational field outside an uncharged rotating massive object, including a rotating black hole.''Cracking the Einstein Code'' by Fulvio Melia, 2009 His solution to Einstein's equations predicted spinning black holes before they were discovered. Early life and education Kerr was born in 1934 in Kurow, New Zealand. He was born into a dysfunctional family, and his mother wa ...[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Roger Penrose
Sir Roger Penrose (born 8 August 1931) is an English mathematician, mathematical physicist, philosopher of science and Nobel Laureate in Physics. He is Emeritus Rouse Ball Professor of Mathematics in the University of Oxford, an emeritus fellow of Wadham College, Oxford, and an honorary fellow of St John's College, Cambridge and University College London. Penrose has contributed to the mathematical physics of general relativity and cosmology. He has received several prizes and awards, including the 1988 Wolf Prize in Physics, which he shared with Stephen Hawking for the Penrose–Hawking singularity theorems, and one half of the 2020 Nobel Prize in Physics "for the discovery that black hole formation is a robust prediction of the general theory of relativity". He is regarded as one of the greatest living physicists, mathematicians and scientists, and is particularly noted for the breadth and depth of his work in both natural and formal sciences.

Andrzej Trautman
Andrzej Mariusz Trautman (born January 4, 1933 in Warsaw) is a Polish mathematical physicist who has made contributions to classical gravitation in general and to general relativity in particular. He made contributions to gravitation as early as 1958. The "Trautman-Bondi mass" is named after him. Biography Trautman was born in Warsaw, Poland into an artistic family. His father, Mieczysław, was a painter and taught drawing at a secondary school in Warsaw. His mother, Eliza Trautman (née André), was French, though she was born in Spain, where her father, Marius André, was working as a French consular officer. His schooling, at the elementary level, was interrupted by the Warsaw Uprising of 1944. After spending about ten months in Germany, he returned, with his mother (his father had died in 1941) to Poland. In the fall of 1945, they both went to Paris, to stay with their family there. In France, Trautman attended a Polish secondary school from which he graduated in 19 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Engelbert Schücking
Engelbert Levin Schücking (May 23, 1926 – January 5, 2015), in English-language works often cited as E. L. Schucking, was a physics professor at New York University in New York City. His research interests were theoretical astrophysics, general relativity and cosmology. Biography Engelbert Levin Schücking was born on May 23, 1926, in Hörde, Westphalia. He manifested an interest in astronomy at a very early age, and by the age of fourteen, he was actively engaged in counting sunspots. He then studied mathematics and physics at the University of Münster, and later at Göttingen. His professors included prolific physicists Werner Heisenberg, Richard Becker and Robert Pohl. He started working in the field of general relativity with the great German physicist Pascual Jordan in Hamburg, in 1952, and he earned his PhD there in 1955. It is with P.Jordan that he found the locus of his life's work, namely the geometric aspects of general relativity and Einstein's field equations. ...

University Of Toronto Press
The University of Toronto Press is a Canadian university press founded in 1901. Although it was founded in 1901, the press did not actually publish any books until 1911. The press originally printed only examination books and the university calendar. Its first scholarly book was a work by a classics professor at University College, Toronto. The press took control of the university bookstore in 1933. It employed a novel typesetting method to print issues of the ''Canadian Journal of Mathematics'', founded in 1949. Sidney Earle Smith, president of the University of Toronto in the late 1940s and 1950s, instituted a new governance arrangement for the press modelled on the governing structure of the university as a whole (on the standard Canadian university governance model defined by the Flavelle commission). Henceforth, the press's business affairs and editorial decision-making would be governed by separate committees, the latter by academic faculty. A committee composed of Vincen ...
