Steven Orszag
Steven Alan Orszag (born February 27, 1943 in New York City , † May 1, 2011 in New Haven , Connecticut ) was an American physicist, engineer and applied mathematician.
Life
Orszag was the son of a lawyer and grew up in Forest Hills, Queens . At the age of 16, he studied at the Massachusetts Institute of Technology (MIT), where he obtained his bachelor's degree in mathematics in 1962, and at Cambridge University (St. Johns College) in 1962/63 . In 1966 he received his doctorate on the theory of turbulence at Princeton University under Martin Kruskal . From 1967 he was a professor of applied mathematics at MIT. From 1984 he was Professor of Engineering at Princeton University. From 1998 he was Professor of Mathematics at Yale University . He was a member of the Institute for Advanced Study in 1966/67 .
From 1970 to 1974 he was a Sloan Research Fellow and 1989/90 Guggenheim Fellow. He was a fellow of the American Physical Society . Orszag received the Otto Laporte Prize , the Fluids and Plasmadynamics Award from the American Institute of Aeronautics and Astronautics, and the GI Taylor Medal from the Society of Engineering Science .
Orszag deals with methods of applied mathematics and numerical analysis, hydrodynamics and turbulence (treatment with renormalization group methods , large eddy simulation), as part of the computer-aided treatment he was also involved in the establishment of a number of companies (Ibrix, Flow Research, Vector Technologies, Exa Corporation). With Carl M. Bender he wrote a textbook on mathematical methods for engineers and natural scientists. He also dealt with chip fabrication and computer data storage.
In numerical analysis he is known as the pioneer of spectral methods for partial differential equations (a term he introduced). He wrote a book about it with David Gottlieb .
He had been married to Reba Karp since 1964 and had three sons. His son Peter is a banker at Citibank and a former budget director in the cabinet of US President Barack Obama .
