The authors compute the multiplicities (density of states) numerically for an Einstein solid - a collection of identical quantum harmonic oscillators. It is shown that if two such…

A simple experiment for the demonstration of percolation problems is reported. Measurements were performed on a sheet of conducting paper after randomly cutting out small square…

The most frequently studied quantities of a statistical variable are its average and standard deviation. Yet, its full distribution often carries very interesting information and can…

Stirling’s approximation to n! and other estimates are developed using elementary arguments. The aim is to shed light on why these approximations work so well. An elementary and…

The authors describe a Monte Carlo algorithm for sampling the density of states directly by doing a random walk in energy space. The probability of a microstate is computed at any…
