John Ziman

from Wikipedia, the free encyclopedia

John Michael Ziman (born May 16, 1925 in Cambridge , † January 2, 2005 ) was a British theoretical solid-state physicist and science activist.

Life

Ziman's father was a civil servant in India and his mother came from a family of rabbinical scholars. His maternal grandfather, Angel Gaster, who was from Romania , was a noted London doctor and one of the founders of the London Jewish Hospital . His brother was Moses Gaster , an eminent scholar, vice-president of the Royal Asiatic Society and leading rabbi of the London Sephardic community.

As a child he moved with his parents to New Zealand , where his father had a farm near Cambridge . He went to school in Hamilton and began studying physics at Victoria University of Wellington in 1943 (Master's degree in 1946). He continued his studies in mathematics and theoretical physics at Balliol College of Oxford University continued where he made 1949 a degree with honors in mathematics. In 1952 he received his doctorate from Stanley Rushbrooke and KWH Stevens with a thesis on electrons in liquid metals in theoretical physics. He was then a lecturer in mathematics at Oxford from 1951 to 1953 and a scholarship from the Pressed Steel Corporation in 1953/54 . He conducted research at the Clarendon Laboratory, first on antiferromagnetism , then in the low-temperature physics group of Francis Simons on liquid helium, electron conduction in metals and transport properties in crystalline lattices. In 1954 he went to Cambridge University as a lecturer in physics , where he became a Fellow of King's College . From 1964 he was professor of theoretical physics at the University of Bristol , where he built up a theory group, including Michael Berry . Since 1966 he has been a lecturer almost annually at the International Center for Theoretical Physics in Trieste, founded by Abdus Salam . From 1982 he was visiting professor in the Department of Humanities at Imperial College London. During the Thatcher administration , he was the first head of the newly founded Science Policy Support Group (SPSG) from 1986 to 1991 .

In the 1950s and 1960s, Ziman undertook fundamental investigations into theoretical solid-state physics, especially in the expansion of the quantum theory of transport phenomena in crystalline solids and as a pioneer in the theory of disordered solids and liquid metals, in which he introduced the use of two-point correlation functions and pseudopotentials. A hallmark of his work was the close connection to the experiment. He is known from various textbooks on theoretical solid state physics ( Condensed Matter Physics ).

Later he dealt mainly with philosophical, educational and sociological questions of the sciences, about which he also wrote several books and essays. This commitment started early. In New Zealand he was temporarily active in the Communist Party and in Oxford in student organizations (International Union of Students, National Union of Students). In 1958/59 he was editor of the Cambridge Review and in 1960 he gave lectures on the radio, from which his book Public Knowledge (1968) emerged.

He observed the development of the sciences primarily from a sociological and political perspective and was one of the founders of the Council of Science and Society (CSS) in 1973 with Paul Sieghart (a lawyer ), which he chaired from 1976 to 1990. In this capacity he was co-author of a number of reports such as Superstar Technologies (1976) on the social control of technology and The world of science and the rule of law (1986, with Paul Sieghart, J. Humphrey) on human rights violations in the field of science in particular in the Soviet sphere of influence. In the 1980s he also campaigned intensively for Soviet dissidents and, among other things, was responsible for the publication of the Medvedev Papers in the West.

He was also active in arms control, but less in the Pugwash conferences , in which he was only briefly active, and more in his own committees in the CSS.

In 1967 he became a Fellow of the Royal Society .

He was married twice (first marriage from 1951 to her death in 2001 with Rosemary Dixon) and had four (adopted) children.
