Derivation of Bose-Einstein Statistics from the Uncertainty Principle

Abstract

The microstate of any degree of freedom of any classical dynamical system can be represented by a point in its two dimensional phase space. Since infinitely precise measurements are impossible, a measurement can, at best, constrain the location of this point to a region of phase space whose area is finite. This paper explores the implications of assuming that this finite area is bounded from below. I prove that if the same lower bound applied to every degree of freedom of a sufficiently-cold classical dynamical system, the distribution of the system's energy among its degrees of freedom would be a Bose-Einstein distribution.
