On Math Jokes (with a new retelling of my favorite one, about a balloon race)
Math jokes are almost universally awful — or, at least, it seems that way to me, since I spend a lot of time around ninth graders. Hearing “Gee, I’m a tree” or “Pi are square? No, pies are round, and … Continue reading

Circumparabolic Regions Inside a Unit Circle
A circumparabolic region is found between a circle and a parabola, with the circle being chosen to include the vertex and xintercepts of the parabola used, with the circle, to define the two circumparabolic regions for a given parabolacircle pair. … Continue reading

Two Versions of a Slowly Rotating Rhombic Triacontahedron, Adorned with Spectral Patterns on Each Face
It took three programs to make this. First, outlines of the “double rainbow” patterns on each face were constructed using Geometer’s Sketchpad. A screenshot from that program was then pasted into MSPaint, which was used to add color to the … Continue reading
