Книга: Abhay Ashtekar «100 Years of Relativity: Space-time Structure Einstein and Beyond»
|
Thanks to Einstein's relativity theories, our notions of space and time underwent profound revisions about a 100 years ago. The resulting interplay between geometry and physics has dominated all of fundamental physics since then. This volume contains contributions from leading researchers, worldwide, who have thought deeply about the nature and consequences of this interplay. The articles take a long-range view of the subject and distill the most important advances in broad terms, making them easily accessible to non-specialists. The first part is devoted to a summary of how relativity theories were born (J Stachel). The second part discusses the most dramatic ramifications of general relativity, such as black holes (P Chrusciel and R Price), space-time singularities (H Nicolai and A Rendall), gravitational waves (P Laguna and P Saulson), the large scale structure of the cosmos (T Padmanabhan); experimental status of this theory (C Will) as well as its practical application to the GPS...

Abhay Vasant Ashtekar (born July 5, 1949) is an Indian theoretical physicist. He is the Eberly Professor of Physics and the Director of the Institute for Gravitational Physics and Geometry at Pennsylvania State University. As the creator of Ashtekar variables, he is one of the founders of loop quantum gravity and its subfield loop quantum cosmology. He has also written a number of descriptions of loop quantum gravity that are accessible to non-physicists. In 1999, Ashtekar and his colleagues were able to calculate the entropy for a black hole, matching a legendary 1974 prediction by Hawking.[2] Oxford mathematical physicist Roger Penrose has described Ashtekar's approach to quantum gravity as "The most important of all the attempts at 'quantizing' general relativity."[3]

Biography
Abhay Ashtekar grew up in several cities, including Mumbai, in the state of Maharashtra, India. After completing his undergraduate education in India, Ashtekar enrolled in the graduate program for gravitation at the University of Texas at Austin.[1] He went on to complete his Ph.D. at the University of Chicago under Prof. Robert Geroch in 1974 (thesis titled: "Asymptotic Structure of the Gravitational Field at Spatial Infinity") and held several appointments at Oxford, Paris, Syracuse before settling at Penn State.[4]
He married Christine Clarke in 1986[5] and the two have a son, Neil.
