Abstract

Experiments and simulations of the photosensitive Belousov-Zhabotinsky reaction are used to study collective behavior of simple interacting elements. Two different types of interacting elements are examined. In a network of excitable elements, interactions change the timing of activity of the individual elements. Interacting chemical wave segments form rotational modes or dynamically align due to their mutual interaction. In both cases, interactions result in emergent group behavior.
