!!! This project is currently CLOSED. There is a new version of API available under LGPL license at https://github.com/gehtsoft-usa/BallisticCalculator1 There is a new version of application in progress (ported to net framework 5.0) https://github.com/nikolaygekht/ballistic.calculator.app Ballisitic Calculator based on JBM's implementation 3-degree of freedom model, ported to C#, improved to support metric system and extended by some math from Litz's "Applied Ballistic" book. Calculator displays ballistic tables, graphs, comparison graph and reticle images. The application is free to use under GNU license

Al2 is a language, close to C++ and Java, designed for use in mathematics and science, but is procedural unlike Mathematica and Maple. Like C++, class operators can be defined. Like Java, there is no need for header files. Aled is an interface to AL2.

Simulation of water waves on the X Windows desktop. Windows and mouse are like ships on the sea. Each movement of these ends up in moving water waves. You can even have rain and/or storm stirring up the water.

OpenGamma is a tool for gamma-ray spectrometry. It performs spectra analysis, including peak search, radionuclide identification and radioactivity determination in samples, allowing full user-defined customization and parameters setting.

Schur is a standalone program for interactively calculating properties of Lie groups and symmetric functions. Schur has been designed to answer questions of relevance to a wide range of problems of interest to chemists, mathematicians, computer scientists,...

PSI is an open-source program for computing molecular properties using high-accuracy, ab initio, quantum mechanical models.

A portable loudspeaker design system supporting measurement, modeling, simulation and optimization of boxes, filters and systems.

This library is a Fortran 95 gnuplot interface for some Unix like OS'es. This provides some routines that enables direct access of a child gnuplot session from a Fortran 95 program. You will need a copy of fortranposix to make this work.

This is the native MS windows release of OpenFOAM, an open source toolbox for Computational Fluid Dynamics (CFD). It was built with MinGW C++ as a set of native windows applications, which improves performance and eliminates the need for Unix emulations.

UPDATED VERSION ON GITHUB! http://github.com/AtiX/wavesim This is a physically correct simulation of waves on a surface, for example water-waves. It can also be used to simulate Microwaves, and has features like the support for different refraction indices, different wave sources and custom borders. Therefore, experiments like the double-slit-experiment can be easily simulated.

Aciqra is a virtual planetarium and sky mapping program which tracks celestial bodies including planets, deep sky objects and stars to an accuracy of a fraction of a degree for thousands of years into both the future and the past. It includes the 2.5 million stars of the Tycho-2 catalog supplemented by data of 120,000 stars from the Hipparcos catalog, 13,000 deep space objects from the NGC and IC catalogs and a large number of asteroids and comets from the Minor Planet Center. The program is platform-independent and can be made to work on most modern computers that support OpenGL.

GXSM -- Gnome X Scanning Microscopy: A multi-channel image and vector-probe data acquisition and visualization system designed for SPM techniques (STM,AFM..), but also SPA-LEED/LEED/LEEM data analysis. A plug-in interface allows any user add-on data-processing and special hardware and instrument support. Latest: NC-AFM and related explorative methods as SQDM can be configured.
