## Mathematics

Maxima
Maxima is a system for the manipulation of symbolic and numerical expressions, including differentiation, integration, Taylor series, Laplace transforms, ordinary differential equations, systems of linear equations, polynomials, and sets, lists, vectors, matrices, and tensors. Maxima yields high precision numeric results by using exact fractions, arbitrary precision integers, and arbitrarily precision floating point numbers. Maxima can plot functions and data in two and three dimensions.
GeoGebra
GeoGebra is a free and multi-platform dynamic mathematics software for schools that joins geometry, algebra and calculus. It received several international awards including the European and German educational software awards.

SAGE is free open source math software that supports research and teaching in algebra, geometry, number theory, cryptography, numerical computation, and related areas. Includes Maxima, Singular, PARI, Matplotlib and other opensource math packages. You can use internet interface (sage-notebok) to access all the features (needs Firefox).
GraphCalc
GraphCalc is an all-in-one solution to everything from everyday arithmetic to statistical analysis, from betas to Booleans, from cubes to calculus, from decimals to derivatives.
It provides user-friendly help and tutorials to guide you through the easy and fun process of mastering GraphCalc.
k3dsurf
K3DSurf is a program to visualize and manipulate Mathematical models in three, four, five and six dimensions. K3DSurf supports Parametric equations and Isosurfaces. It makes mathematics fun.
Yafe
Yet Another Fractal Explorer (Yafe) is an interactive fractal renderer for Windows. It features extremely simple and intuitive user interface and is capable of producing mathematically-sound renderings.
Chaoscope
Chaoscope is a 3D strange attractors rendering software.
Xaos
XaoS is an interactive fractal zoomer. It allows the user to continuously to zoom in or out of a fractal in a fluid, continuous motion. This capability makes XaoS great for exploring fractals, and it’s just plain fun!

## Physics – Chemistry

PhET ( Physics Educational Technology)
Fun, interactive simulations of physical phenomena.
Molecular Workbench
The goal of the NSF-funded Molecular Workbench has been to provide a rich environment that makes the atomic level familiar, predictable, and connected with the macroscopic world, and to understand the effect of such an environment on student learning.

## Astronomy

Stellarium
Planetarium shows a realistic 3D sky in your computer. Just like what you see with the naked eye, binoculars or a telescope, it is being used in planetarium projectors.
kstars
Celestia
You can travel throughout the solar system, to any of over 100,000 stars, or even beyond the galaxy. The exponential zoom feature lets you explore space across a huge range of scales, from galaxy clusters down to spacecraft only a few meters across. A 'point-and-goto' interface makes it simple to navigate through the universe to the object you want to visit.

## Geography

NASA World Wind
World Wind, an open source 3D interactive world viewer, was created by NASA's Learning Technologies project, and released in mid-2004. It is now developed by NASA staff and open source community developers.
World Wind allows any user to zoom from outer space into any place on Earth. World Wind uses satellite imagery and elevation data to allow users to experience Earth terrain in visually rich 3D, just as if they were really there. Virtually visit anyplace in the world. Look across the Andes, into the Grand Canyon, over the Alps or along the African Sahara.

## Scientific calculations and data analysis

Statistik Labor
The Statistical Lab is an explorative and interactive tool designed both to support education in statistics and provide a tool for the simulation and solution of statistical problems. It uses R for statistical computing and visualizing data.
The graphical user interface is designed to make complex statistical relations easy to understand. It connects and displays data frames, frequency tables, random numbers or matrixes in a user-friendly statistical worksheet allowing users to run calculations, conduct analyses and perform multiple simulations and manipulations.

## Design

Dia
Dia is roughly inspired by the commercial Windows program 'Visio', though more geared towards informal diagrams for casual use. It can be used to draw many different kinds of diagrams. It currently has special objects to help draw entity relationship diagrams, UML diagrams, flowcharts, network diagrams, and many other diagrams. It is also possible to add support for new shapes by writing simple XML files, using a subset of SVG to draw the shape.
QCAD
QCad is an application for computer aided drafting in two dimensions (2d). With QCad you can create technical drawings such as plans for buildings, interiors, mechanical parts or schemas and diagrams.
