An Open-structured Random Solid


IN the course of investigations of the fundamental processes underlying flocculation we had occasion to simulate the growth of a floc by a mathematical model. The model chosen was one in which uniform spheres of unit radius are added randomly, one by one, to the growing aggregate, Each sphere is rigidly fixed to the structure at the point at which it first makes contact, and thereafter remains in the same position relative to the other spheres in the aggregate. Such a model has been attempted before1; but in the previous description a truly random addition was not correctly specified, and the results are therefore erroneous.
