Parabolic Beams

I love thinking of parabolas as being formed with a directrix and focus. Coming from a background in trajectory analysis, I find the abstract relationships of the curve to the point and line beautiful. When a light shines through the focus of a parabolic mirror, the light reflected is orthogonal to

Code for Two-Button Calculator

A two-button calculator can only perform two operations (like multiply by two and add five). The Global Math Project is a wonderful resource for math learning and play and has a great resource for two-button problems in this Global Math Project PDF. Another variation of this sort of problem is done

Gold-Phi-nch

Parametric Waves Morphed into Unstable Charcoal

Have you ever wished that you had charcoal that is made of particles that randomly leave and come back? Wish the reference frame would rotate so down is up, but not always? Well now you have what you have always wanted – Unstable Charcoal! I created this after playing with a parametric wave visualiz
