The Celebration Continues: 5,000+ Demonstrations

July 22, 2009 — George Beck, Scientific Information Group

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:

3D Graphics
Quantum Mechanics
Physics
Calculus
Version 7 Features
Mechanical Engineering
College Physics
Finance
Mechanics
Machines
  Optics
Fractals
Plane Geometry
Differential Equations
Art
For Kids
Statistics
Linear Algebra
Business
Probability



These are the top 18 Demonstrations over the last year, with over 10,000 downloads on average:
