This subject had remained in the shadows since the last years of the nineteenth century with Ludwig Boltzmann's work on the kinetic theory of gases and a definition of entropy at the microscopic level. It was even considered to be 'cursed' — Boltzmann committed suicide in How could the irreversibility of real processes at the macroscopic scale be reconciled with the perfect time-reversibility of the classical or quantum law of motion for molecules?
In the s, surrounded by a small group of enthusiastic co-workers, Prigogine began to make crucial progress on this point, developing the first form of non-equilibrium statistical mechanics. Another approach, developed independently by Nikolai Bogolyubov in the Soviet Union, turned out to be equivalent to Prigogine's.
As well as being quite a general formulation of the theory, there were other fruits of this endeavour, for it could be applied to a variety of systems, from gases and solids to plasmas. Pushing the study further, to systems that are far from equilibrium, Prigogine and his increasingly numerous co-workers uncovered an extraordinary phenomenon.

When the distance from equilibrium measured by some appropriate parameter reaches a certain threshold, the trajectory of a system meets a fork, or bifurcation. The system may then leave the trajectory along which it has evolved from equilibrium, and jump to a totally different one. If the system is pushed even further, more bifurcations may appear, and when the system is very far from equilibrium, it may behave completely chaotically as, for example, the regular flow of a liquid may become turbulent.
But, alternatively and unexpectedly, the system might reach a new, ordered state — what Prigogine called a 'dissipative structure'.
Bifurcation point prigogine autobiography summary
Such states are particularly striking in systems in which chemical reactions proceed alongside the effects of diffusion or external forces: ordered structures of different chemical composition appear, which may even propagate as 'chemical waves'. Two ingredients are vital if this is to occur: the 'open' character of the system meaning that it can exchange matter and energy with the external world , and the nonlinear character of the equations governing the evolution of the system.
These conditions arise, in particular, in living systems. Prigogine had thus created an important link between physics, chemistry and biology even extending it to sociology and economics. His achievement was crowned with the award of the Nobel prize for chemistry — the pinnacle of a long list of awards, prizes and honorary degrees.
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: [ citation needed ] first with the introduction of spacetime in general relativity , then with the use of the wave function in quantum mechanics , and finally with the recognition of indeterminism in the study of unstable systems chaos theory.
The Ilya Prigogine Prize for Thermodynamics was initialized in and patronized by Ilya Prigogine himself until his death in It is awarded on a biennial basis during the Joint European Thermodynamics Conference JETC and considers all branches of thermodynamics applied, theoretical, and experimental as well as quantum thermodynamics and classical thermodynamics.
