Brownian Motion App

By Jim | Published: 2022/01/19

Brownian Motion Simulation demonstrates the phenomenon of brownian motion, where microscopic particles display a random walk due to molecular collisions. For instance, particles suspended in liquid move due to random collisions by water molecules that are in constant motion. The Brownian Motion Simulation script was coded in Python and Pygame. To run in the web […]

Interphase: Cross-platform GUI Module

By Jim | Published: 2015/08/02

Interphase is a Python module designed to provide a graphics user interface (GUI) to Pygame applications. Two of my other projects provide Pygame functionality to additional platforms, including PyJ2D for the Java environment and Pyjsdl for the JavaScript environment. Since a dependency of Interphase is Pygame, the module is compatible with the PyJ2D and Pyjsdl […]
