Free software for automation of professional measurement systems, data acquisition, processing and analysis. Especially suitable for scientists who would like to make high-performance, precise measurements in the experimental physics. Features include graphic editor, powerful visual tools, wide set of numeric and symbolic calculations, nonlinear Levenberg-Marquardt regression, ActiveX scripting and more.

DigitizeIt digitizes scanned graphs. Graphs can be loaded in nearly all common image formats (incl. gif,tiff,jpeg,bmp,png) or pasted from the clipboard . Digitizing of line and scatter plots occurs automatically, manual digitizing is also possible. Data values are transformed to a specified axes system and can be saved in ASCII format, ready to use in many other applications. Axes can be linear or logarithmic scale. Can handle tilted graphs.

Einstein's General Theory of Relativity demonstrates that a large mass can deform spacetime and bend the path of light. So, a very massive object, such as a cluster of galaxies can act as a gravitational lens. With this program, one can draw images to see the effect of gravitational lensing. You can easily test the effects of several parameters by changing them and redrawing the image.

Looking Glass is an interactive physics package that helps students visualize and understand the effects of optical components on light rays. While creating and exploring their own lenses and mirrors, students encounter the core concepts in optics.

Making Waves is an interactive physics package that helps students visualize and understand the motion and interference of transverse and longitudinal waves. While creating and exploring their own wave simulations, students encounter the core concepts in wave theory.

Newton's Aquarium is an interactive physics package that helps students visualize and understand Newton's Law of Universal Gravitation. While creating and exploring their own solar systems, students encounter the core concepts in classical physics.
