The Wolfram Demonstrations Project contains thousands of free interactive visualizations, with new entries added daily.
This Demonstration shows the paths of contour integrals over some basic complex functions. The upper-left panel is the original complex z-plane. Use the mouse to draw a contour in the z-plane. The upper-right panel shows the image of the z-plane using t...

The Wolfram Demonstrations Project contains thousands of free interactive visualizations, with new entries added daily.
This Demonstration shows the temperature and concentration profiles of an insulated tubular reactor in which a first-order, irreversible reaction AOverscriptBox[?, k]B takes place in a fluid undergoing laminar flow. Assuming that temperature does not af...

![Constructing a Regular Heptadecagon (17-gon) with Ruler and Compass
http://demonstrations.wolfram.com/ConstructingARegularHeptadecagon17GonWithRulerAndCompass
The Wolfram Demonstrations Project contains thousands of free interactive visualizations, with new entries added daily.
The number 17 is a Fermat prime, which means it is of the form 2^2^n+1, with n=2. In 1796, Gauss discovered that regular polygons with a Fermat number of sides can be constructed using only a straight edge and compass [1]. Gauss showed, in particular, t...
