Abstract
The coarsening process of froths and foams is described statistically in two dimensions by a ‘‘random-neighbor model.’’ This nonlinear dynamical model contains no free parameters; all rates are determined dynamically. It describes normal growth, agrees with experimental results, throws light on old data, and, hopefully, inspires new simulations and measurements. Lewis’s law [Anat. Rec. 38, 341 (1928); Am. J. Bot. 30, 74 (1943)], and some other properties, can be derived analytically from the model.
