Ilya, Viscount Prigogine (Russian: Илья́ Рома́нович Приго́жин) (January 25, 1917 – May 28, 2003) was a Belgian physicist and Nobel Laureate chemist noted for his work on dissipative structures, complex systems, and irreversibility.
Biography
Prigogine was born in Moscow a few months before the Russian Revolution of 1917. His father, Roman Prigogine, was a chemical engineer at the Moscow Institute of Technology. Because the family was critical toward the new Soviet system, they left Russia in 1921. They first went to Germany and in 1929 to Belgium, where Prigogine received Belgian nationality in 1949.
Prigogine studied chemistry at the Free University of Brussels, now split into the Université Libre de Bruxelles and the Vrije Universiteit Brussel, where in 1950 he became professor. In 1959, he was appointed director of the International Solvay Institute in Brussels, Belgium. In that year he also started teaching at the University of Texas at Austin in the United States, where he later was appointed Regental Professor and Ashbel Smith Professor of Physics and Chemical Engineering. In 1967 he co-founded there what is now called The Center for Complex Quantum Systems. In that year he also returned to Belgium where he became director of the Center for Statistical Mechanics and Thermodynamics.
He was a member of numerous scientific organizations, and received numerous awards, prizes and 53 honorary degrees. In 1955 Ilya Prigogine was awarded the Francqui Prize for Exact Sciences. For this study in irreversible thermodynamics he received the Rumford Medal in 1976 and in 1977 the Nobel Prize in Chemistry. In 1989 he was awarded the title of Viscount by the King of Belgium. Until his death he was president of the International Academy of Science and was in 1997 one of the founders of the International Commission on Distance Education (CODE), a worldwide accreditation agency.
Work
Prigogine is known best due to his definition of dissipative structures and their role in thermodynamic systems far from equilibrium, a discovery that won him the Nobel Prize in Chemistry in 1977.
Dissipative structures theory
Dissipative structure theory led to pioneering research in self-organizing systems, as well as philosophic inquiries into the formation of complexity on biological entities and the quest for a creative and irreversible role of time in the natural sciences.
His work is seen by many as a bridge between natural sciences and social sciences. With University of Texas at Austin professor Robert Herman, he also developed the basis of the two fluid model, a traffic model for urban networks, using Bose-Einstein Condensation theory in traffic engineering.
Other Works
In his later years, his work concentrated on the mathematical role of determinism in nonlinear systems on both the classical and quantum level. He proposed the use of a rigged Hilbert space in quantum mechanics as one possible method of achieving irreversibility in quantum systems. He also co-authored several books with Isabelle Stengers, including End of Certainty and the classical book La Nouvelle Alliance (The New Alliance).
The End of Certainty
In his 1997 book, The End of Certainty, Prigogine contends that determinism is no longer a viable scientific belief. "The more we know about our universe, the more difficult it becomes to believe in determinism." This is a major departure from the approach of Newton, Einstein and Schroedinger, all of whom expressed their theories in terms of deterministic equations. According to Prigogine, determinism loses its explanatory power in the face of irreversibility and instability.
Prigogine traces the dispute over determinism back to Darwin, whose attempt to explain individual variability according to evolving populations inspired Ludwig Boltzmann to explain the behavior of gases in terms of populations of particles rather than individual particles. This led to the field of statistical mechanics and the realization that gases undergo irreversible processes. In deterministic physics, all processes are time-reversible, meaning that they can proceed backward as well as forward through time. As Prigogine explains, determinism is fundamentally a denial of the arrow of time. With no arrow of time, there is no longer a privileged moment known as the "present," which follows a determined "past" and precedes an undetermined "future." All of time is simply given, with the future as determined as the past. With irreversibility, the arrow of time is reintroduced to physics. Prigogine notes numerous examples of irreversibility, including diffusion, radioactive decay, solar radiation, weather and the emergence and evolution of life. Like weather systems, organisms are unstable systems existing far from thermodynamic equilibrium. Instability resists standard deterministic explanation. Instead, due to sensitivity to initial conditions, unstable systems can only be explained statistically, that is, in terms of probability.
Prigogine asserts that Newtonian physics has now been "extended" three times, first with the use of the wave function in quantum mechanics, then with the introduction of spacetime in general relativity and finally with the recognition of indeterminism in the study of unstable systems.
