We start with a random initial world, and come out with the regularities, which mimic various empirical data [3] for the present languages.7 pages, 4 figuresPhysics and SocietyComputational PhysicsThe physics of randomness and regularities for languages (lifetimes, family trees, and the second languages); in terms of random matricestext
