Abraham Taub
Abraham Haskel Taub (; February 1, 1911 – August 9, 1999) was a distinguished American mathematician and physicist, well known for his important contributions to the early development of general relativity, as well as differential geometry and differential equations. Work In a 1948 paper dealing with relativistic shock waves, Taub introduced a relativistic generalization of the Rankine-Hugoniot jump conditions across a shock, which is now known as the ''Taub Adiabat.'' He also introduced the Taub–NUT space in general relativity. Taub graduated in 1931 with a bachelor's degree in mathematics and physics from the University of Chicago. He earned his doctorate at Princeton University in 1935, under the direction of the prominent relativist Howard P. Robertson. At Princeton, Taub was also influenced by Oswald Veblen. After a postdoctoral year at the Institute for Advanced Study, Taub became an assistant professor at the University of Washington in Seattle. In 1948, Abe Taub w ...

Taub–NUT Space
The Taub–NUT metric (,McGraw-Hill ''Science & Technology Dictionary'': "Taub NUT space" ) is an exact solution to Einstein's equations. It may be considered a first attempt in finding the metric of a spinning black hole. It is sometimes also used in homogeneous but anisotropic cosmological models formulated in the framework of general relativity. The underlying Taub space was found by , and extended to a larger manifold by , whose initials form the "NUT" of "Taub–NUT". Taub's solution is an empty space solution of Einstein's equations with topology R×S3 and metric (or equivalently line element) :g =-dt^2/U(t) + 4l^2U(t)(d\psi+ \cos\theta d\phi)^2+(t^2+l^2)(d\theta^2+(\sin\theta)^2d\phi^2) where :U(t)=\frac and ''m'' and ''l'' are positive constants. Taub's metric has coordinate singularities at U=0, t=m+(m^2+l^2)^, and Newman, Tamburino and Unti showed how to extend the metric across these surfaces. When Roy Kerr developed the Kerr metric The Kerr metric or Kerr geom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

University Of Washington Press
The University of Washington Press is an American academic publishing house. The organization is a division of the University of Washington, based in Seattle. Although the division functions autonomously, they have worked to assist the university's efforts in support of the Burke Museum of Natural History and Culture, the Henry M. Jackson School of International Studies, and the Center for Innovation and Research in Graduate Education. Since 1915, they have published the works of first-time writers, including students, poets, and artists, along with authors known throughout the world for their work in the humanities, arts, and sciences. While the day-to-day functions of the organization are carried out independent of the university, the imprint itself is managed by a committee of faculty members, who have been appointed by the university president. Each manuscript must go through a collaborative approval process overseen by the editors and the University Press Committee before b ...

ILLIAC I
The ILLIAC I (Illinois Automatic Computer), a pioneering computer in the ILLIAC series of computers built in 1952 by the University of Illinois, was the first computer built and owned entirely by a United States educational institution. Computer The project was the brainchild of Ralph Meagher and Abraham H. Taub, who both were associated with Princeton's Institute for Advanced Study before coming to the University of Illinois. The ILLIAC I became operational on September 1, 1952. It was the second of two identical computers, the first of which was ORDVAC, also built at the University of Illinois. These two machines were the first pair of machines to run the same instruction set. ILLIAC I was based on the IAS machine Von Neumann architecture as described by mathematician John von Neumann in his influential ''First Draft of a Report on the EDVAC''. Unlike most computers of its era, the ILLIAC I and ORDVAC computers were twin copies of the same design, with software compatibility. ...
