    • Abstract:
      Describes the natural process of spontaneous pattern formation and gives examples from traffic, conduction, convection, leopard spots, and others. Progress in efforts to form a theory to explain patterns in nature; Pattern formation through spontaneous symmetry breaking; Other important concepts, including the reaction-diffusion system, Turing patterns, excitable media, the order parameter, viscosity, stability thresholds; Implications of pattern formation in dendritic growth; Fractals; Spiral defect chaos. INSETS: Kinds of convection;Dendrites.
