Herbert S. Green

Herbert ( " Bert" ) Sydney Greenstreet ( born December 17, 1920 in Ipswich, † February 16, 1999 in Adelaide ) was a British- Australian theoretical physicist.

Life

Green studied mathematics at the Royal College of Science in 1941 and made his bachelor's degree with honors from the University of London (Imperial College). His teachers have included Sydney Chapman and William Penney. During World War II he was from 1941 to 1945 as an officer in the Meteorological Service of the Royal Air Force. After that he went to the University of Edinburgh, where he received his doctorate in physics in 1947 with Max Born ( Ph. D., A General Kinetic Theory of Liquids), then ICI Fellow, and in 1949 again received his doctorate (D. Sc., A unitary quantum electrodynamics ). 1949/50, he was at the Institute for Advanced Studies and 1950/51 at the Dublin Institute for Advanced Studies ( with Erwin Schrödinger ). From 1951 until his retirement in 1985, he was Professor of Mathematical Physics at the University of Adelaide and at times Dean of the Faculty of Mathematics. He has been a visiting professor at the University of Florida, Michigan State University and the University of Arizona.

With Max Born, he worked in statistical physics, specifically kinetic equations for liquids and gases. The BBGKY hierarchy, a Integrodifferentialgleichungssystem that links each the phase space distribution function for a group of n interacting particles from a large set of N particles of the (n 1 ) particles distribution function, here by two and by J. Yvon ( 1935), John G. Kirkwood (1946) and Nikolai Nikolaevich Bogolyubov (1946 ) named. Starting point of the formalism is the classical Liouville equation. Green expanded the treatment on the quantum mechanical case with applications in liquid helium.

He also addressed, among others, nuclear physics, cosmic rays, elementary particle physics and quantum field theory and general with the basics of quantum mechanics well as with plasma physics (partly in collaboration with Roy Leipnik ). Later he turned to the functioning of the brain. After Green have quantum mechanical processes affect fundamental information processing in the brain, which is thus classified as a kind of quantum Turing machine. He wrote two books about it.

Green also dealt with environmental physics such as the spread of pollutants, which also led to a confrontation with the Australian provincial government in 1984, as Green Environmental hazards in a planned petrochemical plant on Spencer Gulf and saw this also represented on television. The project was later abandoned.

In 1954 he became a Fellow of the Australian Academy of Sciences. 1974 to 1976 he was president of the Australian Mathematical Society. He was also a member of the Royal Zoological Society of South Australia and the Australian Institute of Physics.

He was married in 1951 and had two children.
