Wolfram Demonstrations Project

Link via Wolfram

Conceived by Mathematica creator and scientist Stephen Wolfram as a way to bring computational exploration to the widest possible audience, The Wolfram Demonstrations Project is an open-code resource that uses dynamic computation to illuminate concepts in science, technology, mathematics, art, finance, and a remarkable range of other fields.

Its daily-growing collection of interactive illustrations is created by Mathematica users from around the world, who participate by contributing innovative Demonstrations.

From elementary education to front-line research, topics span an ever-growing array of categories. Some Demonstrations can be used to enliven a classroom or visualize tough concepts, while others shed new light on cutting-edge ideas relevant to high-level workgroups and thesis research. Each is reviewed for content, clarity, and presentation, edited by experts at Wolfram Research to ensure quality and reliability.

All Demonstrations run freely on any standard Windows, Mac, Unix, or Linux computer. In fact, you don’t even need Mathematica to benefit. Anyone can preview a Demonstration online, and interact with it using the free Mathematica Player. Those with Mathematica can also experiment with and modify the code on their own computers.
