Dissipative Structures

Finding
Classical thermodynamics establishes that isolated systems tend toward disorder. Prigogine showed that open systems far from equilibrium can spontaneously generate ordered structures by dissipating energy. Benard convection cells, the Belousov-Zhabotinsky reaction, hurricanes, and living organisms are all dissipative structures. The order is not despite the second law but because of it: the system exports entropy to its environment, maintaining local order at the cost of global disorder.
Pattern Mapping
Alignment — Dissipative structures align energy flow with pattern formation. The structure exists because the energy flow exists; remove the gradient and the structure collapses. Pattern and sustaining condition are the same thing.
Proportion — Structures form at specific threshold conditions (e.g., the Rayleigh number). Below: no pattern. Above: ordered pattern. The transition is sharp and proportional to the driving force.
Non-fabrication — Prigogine explicitly distinguished his result from vitalism. The order is explained by thermodynamics, not by invoking a principle outside physics.

Status
Established thermodynamics, Nobel Prize 1977. Extension to biological systems is legitimate in principle; quantitative application remains active. See Nicolis & Prigogine, Self-Organization in Nonequilibrium Systems (1977). The mapping to the five properties is this project’s structural interpretation.
