Raymond Frederick Streater (born 1936) is a British physicist, and professor emeritus of Applied Mathematics at King's College London. He is best known for co-authoring a text on quantum field theory, the 1964 PCT, Spin and Statistics and All That.
Ray Streater was born on 21 April 1936 in Three Bridges in the parish of Worth, Sussex, England, United Kingdom, the second son of Frederick Arthur Streater (builder) (1905-1965) and Dorothy Beatrice Streater, née Thomas (17 December 1907 - 16 December 1994). He married Mary Patricia née Palmer on 19 September 1962, and they had three children: Alexander Paul (1963); Stephen Bernard (1965); Catherine Jane Mary (1967).
Professor Streater's career may be summarised as follows.
Streater co-authored a classic text on mathematical quantum field theory, reprinted as
PCT, Spin and Statistics and All That (written jointly with Wightman, A. S.), 2000, Princeton University Press, Landmarks in Mathematics and Physics (paperback); first published in 1964 by W. A. Benjamin. The title is an homage to 1066 and All That.
He has also become interested in the dynamics of quantum systems that are not in a pure state, but are large. This is expressed in
Statistical Dynamics: A Stochastic Approach to Nonequilibrium Thermodynamics, 1995, Imperial College Press (hardback, paperback). This work was simplified and extended in the second edition, published in 2009.
