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. Interactive computational resources have typically been scattered across the web. Moreover, their creation requires specialized programming knowledge, making them difficult and expensive to develop. As a result, their breadth and reach are limited. With its debut in 2007, the Wolfram Demonstrations Project introduced a new paradigm for exploring ideas, providing a universal platform for interactive electronic publishing. The power to easily create interactive visualizations, once the province of computing experts alone, is now in the hands of every Mathematica user. More importantly, anyone around the world can freely use these thousands of fully functional 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 complex concepts, while others shed new light on cutting-edge ideas from academic and industrial workgroups. Each is reviewed and edited by experts for content, clarity, presentation, quality, and reliability.

All Demonstrations run freely on any standard Windows, Mac, or Linux computer. In fact, you do not even need Mathematica. You can interact with any Demonstration using the free Wolfram CDF Player . If you have Mathematica you can also experiment and modify the code yourself. Demonstrations can be created with just a few short lines of code. This opens the door for researchers, educators, students, and professionals at any level to create their own sophisticated mini-applications, then publish and share them with the world using Wolfram's Computable Document Format (CDF). The Wolfram Demonstrations Project is part of the family of free online services from Wolfram Research—these include Wolfram|Alpha, the world's first computational knowledge engine; MathWorld, the number one mathematics website; as well as The Wolfram Functions Site, WolframTones, and more.
