Query: Statistical Mechanical Approach to Human Language   We use the formulation of equilibrium statistical mechanics in order to study
some important characteristics of language. Using a simple expression for the
Hamiltonian of a language system, which is directly implied by the Zipf law, we
are able to explain several characteristic features of human language that seem
completely unrelated, such as the universality of the Zipf exponent, the
vocabulary size of children, the reduced communication abilities of people
suffering from schizophrenia, etc. While several explanations are necessarily
only qualitative at this stage, we have, nevertheless, been able to derive a
formula for the vocabulary size of children as a function of age, which agrees
rather well with experimental data.
