This script returns the convex hull (separated into upper and lower chains of vertices) and the diameter (farthest pair of points), given input consisting of a list of 2d points represented as pairs (x,y). The convex hull algorithm is Graham's scan, using a coordinate-based sorted order rather... Platforms: Windows, Mac, *nix, Python, BSD Solaris

cstodconverter is a specially designed utility that uses particle scattering data to convert a particle's scattering cross section to a diameter. This is usually non-trivial because scattering cross section is a nonlinear and non-monotonic function of diameter. The software is targetted at... Platforms: Windows

The Eratosthenes model displays the shadows cast by two gnomons (sticks) at different locations on Earth. For one gnomon, Sun is directly overhead (as would be the case if the gnomon was on the Tropic of Cancer at the summer solstice). The other gnomon is due north of the first gnomon. The sizes...
