Dissipative structure theory, proposed by the Belgian physical chemist Ilya Prigogine, describes open systems that are far from thermodynamic equilibrium. These systems continuously exchange matter and energy with their surroundings, and through nonlinear interactions, evolve from disorder to order, forming and maintaining stable, self-organized structures. Such structures remain stable precisely because they constantly "dissipate" energy and matter to counteract the tendency toward increasing entropy as dictated by the second law of thermodynamics. The theory emphasizes the importance of openness, non-equilibrium conditions, nonlinearity, and fluctuations, identifying these as prerequisites for the emergence of new order and complexity in systems. It reveals that the ordered patterns observed in many natural phenomena—such as the origin of life and ecosystem evolution—do not arise from pre-existing blueprints, but rather emerge dynamically from interactions between the system and its environment.
