PRIGOGINE ILYA ROMANOVICH

PRIGOGINE ILYA ROMANOVICH WAS BORNJANUARY 25, 1917 IN MOSCOW. IN BELGIUM SHE WAS BROUGHT BY HER PARENTS FROM RUSSIA IN EARLY CHILDHOOD.

HE IS BELGIAN PHYSICIST AND PHYSICAL CHEMIST, NOBEL PRIZE IN CHEMISTRY 1977 "FOR HIS WORK ON THERMODYNAMICS OF IRREVERSIBLE PROCESSES, PARTICULARLY THEORY OF DISSIPATIVE STRUCTURES. "

PRIGOGINE HIS STUDENT YEARS TOOK AN ACTIVE PART IN THE CREATION OF THERMODYNAMICS OF IRREVERSIBLE PROCESSES. N 1947 HE INTRODUCED THE CONCEPT I OF ENTROPY PRODUCTION AND RE-FORMULATED THE SECOND LAW OF THERMODYNAMICS, EXTENDING IT TO THE SO-CALLED OPEN SYSTEMS THAT EXCHANGE WITH THE EXTERNAL ENVIRONMENT OF MATTER AND ENERGY. 1947 SHOWED THAT THE STEADY STATE AT FIXED EXTERNAL PARAMETERS ENTROPY PRODUCTION RATE IS MINIMUM AND THERMODYNAMIC SYSTEM THAT PROCESSES IRREVERSIBLE ENTROPY PRODUCTION SPEED IN AN OPEN SYSTEM SEEKS TO MINIMIZEIN. RECIPROCITY L. 1959 -69 R. BROUGHT RELATIONS OF M ONSAGER OF KINETIC EQUATIONS AND THERMODYNAMIC RELATIONS FOR A NONEQUILIBRIUM GAS.

SINCE 1962 RIGOGINE LEADING THEINTERNATIONAL SOLVAY P INSTITUTES OF CHEMISTRY AND PHYSICS IN BRUSSELS, AND FROM 1967 - CENTER OF STATISTICAL MECHANICS AND THERMODYNAMICS OF THE UNIVERSITY OF TEXAS AT AUSTIN, WHERE HE ESTABLISHED A SCHOOL OF NONEQUILIBRIUM NONLINEAR PHYSICS.

PRIGOGINE AND HIS COLLABORATORS OFFERED ONE OF THE MOST EFFECTIVE MATHEMATICAL MODELS OF OSCILLATORY HOMOGENEOUS - THE SO-CALLED RUSSELATOR (FROM " RUSSELS" AND B B "OSCILLATOR"). BRUSSELATOR BECAME THE BASIS OF THE DESCRIPTION OF DISSIPATIVE STRUCTURES - STRUCTURES THAT ARISE IN NONLINEAR NONEQUILIBRIUM OPEN SYSTEMS OF DIFFERENT NATURE - CHEMICAL (BATCH REACTIONS, LEADING CENTERS, SPIRALS), BIOLOGICAL (BIOLOGICAL CLOCK), PHYSICAL (DISSIPATIVE STRUCTURES IN SOLIDS), ECONOMIC (FLUCTUATIONS ON THE STOCK EXCHANGE ) ETC.
