A 2D java physics engine, a port of the C++ Box2d engine. This is the core physics engine.
Piccolo2D particle system physics integration.
A simple particle system physics engine for Processing.
Redberry is an open source computer algebra system designed for tensor manipulation. It implements basic computer algebra system routines as well as complex tools for real computations in physics. This module contains the implementation of special routines needed in real physical problems. It contains tools for such problems like Feynman graphs and one-loop counterterms calculation etc.
Real-time 3D physics library for Java, based on the ReactPhysics3D library.
