Dissipative Structures

Gray-Scott reaction-diffusion: U + 2V → 3V (autocatalysis), V → P (decay). Prigogine's non-equilibrium self-organization.

Presets

Parameters

Feed rate F 0.055

Kill rate k 0.062

D_U 0.20

D_V 0.05

Step: 0

∂U/∂t = D_U∇²U − UV² + F(1−U)
∂V/∂t = D_V∇²V + UV² − (F+k)V

Prigogine (1977 Nobel): order emerges far from equilibrium. Turing (1952): diffusion-driven instability.
