The Microcanonical Entropy model considers an isolated system consisting of N identical, non-interacting quantum particles with energy E.  We wish to determine the entropy of the system S(N,E).  For fixed total energy E, we compute the entropy by considering a system of N distinguishable particles to be composed of a subsystem of (N - 1) particles and a subsystem of 1 particle. The model displays the entropy S(N,E) and the computation time as users vary the number of particles N and the total energy E.  This model is a supplemental simulation for the article "Enhancing the understanding of entropy through computation" in the American Journal of Physics 79(11), 1127-1132 (2011).

The Microcanonical Entropy model was developed by Wolfgang Christian, Trisha Salagaram, and Nithaya Chetty using the Easy Java Simulations (EJS) modeling tool.  It is distributed as a ready-to-run (compiled) Java archive.  Double clicking the  ejs_stp_MicrocanonicalEntropy.jar file will run the program if Java is installed.

Please note that this resource requires at least version 1.5 of Java.
