Considered one of the founders of complexity science, Ilya Prigogine received the Nobel Prize in Chemistry in 1977 for "his contributions to nonequilibrium thermodynamics, particularly the theories of dissipative structures." According to The Univeristy of Texas at Austin, Prigogine developed the concept of "dissipative structures" to describe the coherent space-time structures that form in open systems in which an exchange of matter and energy occurs between a system and its environment. He was a leader in the fields of nonlinear chemistry and physics, and his research helped create a greater understanding of the role of time in the physical sciences and biology.
