Main Document

Ejs STP MonteCarloPi Model 

written by Wolfgang Christian, Anne Cox, Harvey Gould, and Jan Tobochnik

The Monte Carlo Pi program program uses a Monte Carlo routine to approximate pi by approximating the area of a unit circle. The program is distributed as a ready-to-run (compiled) Java archive. Double-clicking the ejs_stp_MonteCarloPi.jar file will run the program if Java is installed on your computer.

The program was created using Ejs (Easy Java Simulations). You can modify this program and see how it is designed if you have Ejs installed by right-clicking within the window and selecting Open Ejs Model from the pop-up menu. Ejs, a part of the Open Source Physics Project, is designed to make it easier to access, modify, and generate computer models. Information about Ejs is available at

Additional Open Source Physics programs for Statistical and Thermal Physics can be found by searching ComPADRE for Open Source Physics, STP or Statistical and Thermal Physics.
