Tastefully done, I would say. The target audience consists not of this blog’s readers, but rather of their children.

The Age of Graphical Computing
January 3, 2010Ron Doerfler has created a truly gorgeous 2010 calendar titled The Age of Graphical Computing. Ron has transformed nomography into a form of art.

The calendar is free and available for downloading and printing in two formats (PDF files of about 5 MB):
- Flip-up landscape printing with binding: with major U.S. holidays, with no holidays.
- Double portrait printing with stapling: with major U.S. holidays, with no holidays.
Most nomograms in this calendar were created using PyNomo.

Geometry with POV-Ray
July 28, 2009If you would like to use POV-Ray to visualize 3-dimensional geometrical objects, I highly recommend Friedrich A. Lohmueller‘s beautiful tutorial on Analytical Geometry with POV-Ray. Other POV-Ray tutorials by Friedrich A. Lohmueller can be found here.

In my humble opinion, this is how Analytical Geometry should be taught. Descartes had no access to 3-d graphics. We do. Why not take advantage of the technology?
