Wolfram Demonstrations Challenge

As a long-time developer at Wolfram Research, I can attest that the job requires superhuman discipline and self-control. Those who lack fortitude are soon undone by the irresistible functionality we build into Mathematica and spend their days exploring the esoteric topics they’ve always wondered about instead of building more great technology.

The situation has recently gotten worse.

Today we are pleased to announce an exciting new phase in the development of the Wolfram Demonstrations Project. In addition to its slick new design and structure, allowing for more intuitive navigation, the website now features a groundbreaking technology that takes interactivity on the web to a whole new level. This technology tightly integrates live computations into the web browser, making interaction with Demonstrations a fluent part of the online experience.

Powered by a new web browser plugin, each Demonstration’s dynamic interface is now an element of the web page, similar to text, images, or videos, and yet is so much more than the typical inert content. Sliders, buttons, 3D graphic manipulations, color palettes, and the rest of the Wolfram interactive arsenal are now at your fingertips. They provide dynamic access to Mathematica’s universal engine spanning vast areas of pure and applied math, image processing, finance, control systems, wavelet analysis, and much more.

Iteration usually increases complexity. For example, ponder the following “Fractal Maze”. The green lines mark the boundaries of a frame that shows the black paths of a maze. Copies of that frame and the paths are copied inside. With 4 levels of nested frames, it is possible to get from 1 to 8 on the outer frame. When pictures are repeated inside themselves, it’s usually called the Droste effect.

Pick some points at random. What can be said about them? What curves go through them? What polygons and polynomials can be made from them? Deep mathematics lurks behind these questions, but the answers can be explored just by moving points around within some Wolfram Demonstrations.

Simply by moving points you can see deep mathematics in action.

For example, “Five Points Determine a Conic Section” (Ed Pegg Jr and Paul Abbott) uses a matrix determinant on five points to produce an equation going through all five points.

You already know that Mathematica can do anything technical—modeling, simulation, development, documentation, and so on.

But it’s also a great tool for relaxing. When you need to take a break from your engineering project or math homework, you don’t have to shut down Mathematica. Clear your head with one of these fun activities created by Mathematica users for the Wolfram Demonstrations Project.

Last week we proudly celebrated the milestone of 5,000 Demonstrations. As each one is a separate program, this represents a huge collaborative software development.

And now, every Demonstration has its preview animation available on YouTube. Each has a unique soundtrack created with variations on a custom WolframTones selection.

Some facts and figures: over the last year, there have been nearly 14 million visits to all Demonstrations pages, with 3.5 million unique visitors to the main site. As stated in the previous blog post, Demonstrations have been viewed over 6 million times. Over 1 million notebooks have been downloaded using the Mathematica Player and over half a million source notebooks have been downloaded.

Here are the top Demonstration topics:

Today we passed a remarkable milestone: the 5,000th Demonstration was published by the Wolfram Demonstrations Project, the free, interactive resource we created in 2007.

This makes the Demonstrations Project the largest collection of open, instructional applets anywhere. And it’s also much needed proof that you can create a viable and vibrant technical publishing ecosystem based on interactive applications rather than dead documents—pivotal to moving technical communication into a major new era.

What’s the significance of this?

Have you ever wanted a set of straightforward, step-by-step instructions for solving a problem or accomplishing a specific task with Mathematica? Have you ever thought that a Mathematica “quick-reference guide” would be useful? If so, take a look at the “How To” Topics in Version 7. “How tos” are a new type of documentation in Mathematica 7 that provide just the information you need without a lot of detailed background information.

This task-oriented approach makes these “How tos” ideal for those getting started with Mathematica. Some students, educators, researchers, and others that would benefit from using Mathematica feel that it would take too long to learn, or is just too complex to use. While this sentiment might seem reasonable given the computational power and breadth of features available in Mathematica, it couldn’t be further from the truth.

Recently, I had the pleasure of discussing some pieces of the Mathematica universe with distinguished scientists, forward-looking educators, and a lot of excitable kids at the annual meeting of the American Association for the Advancement of Science (AAAS). Showing newcomers some of the magic we make here at Wolfram Research is always fun, and one of the best ways to introduce them to the types of things that we like to build is the Wolfram Demonstrations Project.

Just a couple of weeks ago we released Mathematica 7. This week we’ve made the Wolfram Demonstrations Project live with Mathematica 7.

All the 4270 Demonstrations on the site run with Mathematica 7 (yes, we tested every single one of them, partly automatically, partly by hand).

And we added 147 new Demonstrations that specifically make use of Mathematica 7’s features.

Most of those Demonstrations were created internally within Wolfram Research, in a small frenzy of activity right around the actual release of Mathematica 7.

I was involved in organizing this Demonstrations-fest. It’s very impressive how quickly it’s possible to create so much high-quality material with Mathematica. Of course, it helped that we were able to work directly with the key developers of much of Mathematica 7’s functionality—so people were often creating Demonstrations based on the very features they had implemented in the system.

The new image processing system in Mathematica 7 was a particularly fertile source of Demonstrations. Charting, splines and vector visualization are other areas that have spawned all sorts of interesting Demonstrations.

Here are a few of my personal favorites:
