Valentin Turchin

Valentin Fyodorovich Turchin (Валенти́н Фёдорович Турчи́н, 14 February 1931 in Podolsk – 7 April 2010 in Oakland, New Jersey ) was a Soviet and American physicist, cybernetician, and computer scientist.

He developed the Refal programming language, the theory of metasystem transitions and the notion of supercompilation.

He was a pioneer in artificial intelligence and a proponent of the global brain hypothesis.

Turchin was born in 1931 in Podolsk, Soviet Union.

In 1952, he graduated from Moscow University with a degree in Theoretical Physics, and got his Ph.D. in 1957.

In the 1960s, Turchin became politically active.

After working on neutron and solid-state physics at the Institute for Physics of Energy in Obninsk, in 1964 he accepted a position at the Keldysh Institute of Applied Mathematics in Moscow.

There he worked on statistical regularization methods and authored REFAL, one of the first AI languages and the AI language of choice in the Soviet Union.

In Fall 1968, he wrote the pamphlet The Inertia of Fear, which was

In 1970 he authored "The Phenomenon of Science", a grand cybernetic meta-theory of universal evolution, which broadened and deepened the earlier book.

By 1973, Turchin had founded the Moscow chapter of Amnesty International with Andrey Tverdokhlebov and was working closely with the well-known physicist and Soviet dissident Andrei Sakharov.

In 1974 he lost his position at the Institute, and was persecuted by the KGB.

quite widely circulated in samizdat, the writing began to be circulated under the title The Inertia of Fear: Socialism and Totalitarianism in Moscow in 1976.

Following its publication in the underground press, he lost his research laboratory.

Facing almost certain imprisonment, he and his family were forced to emigrate from the Soviet Union in 1977.

He went to New York, where he joined the faculty of the City University of New York in 1979.

In 1990, together with Cliff Joslyn and Francis Heylighen, he founded the Principia Cybernetica Project, a worldwide organization devoted to the collaborative development of an evolutionary-cybernetic philosophy.

In 1998, he co-founded the software start-up SuperCompilers, LLC.

He retired from his post of Professor of Computer Science at City College in 1999.

A resident of Oakland, New Jersey, he died there on 7 April 2010.

He has two sons named Peter Turchin and Dimitri Turchin.

Peter Turchin is a specialist in population dynamics and the mathematical modeling of historical dynamics.

The philosophical core of Turchin's scientific work is the concept of the metasystem transition, which denotes the evolutionary process through which higher levels of control emerge in system structure and function.

Turchin uses this concept to provide a global theory of evolution and a coherent social systems theory, to develop a complete cybernetics philosophical and ethical system, and to build a constructivist foundation for mathematics.

Using the REFAL language he has implemented Supercompiler, a unified method for program transformation and optimization based on a metasystem transition.
