Scaling state in froths deduced from a corrected von Neumannʹs law

A corrected and generalized von Neumannʹs law is proposed, so that its statistical consequences agree with all experiments reported in the literature. It is shown that a frothʹs scaling state, concerning the surface area distribution, may be deduced from the stochastical independence between the number of sides distribution and the bubblesʹ surface area, and on the simple change of von Neumannʹs law from dA/dt = k(n − 6) to dA/dt = kA(n − 6).
