I really should have paid more attention in class for Geometry.
I got side-tracked by computers. Thanks for the post, it helps me round out my largely informal education :)
I don't know if you take suggestions, but I'd love to see something about fractals and specifically bifurcation diagrams if you are so inclined.
Hmmm...Sounds like a great topic for a future post! Thanks for the kind words and the awesome suggestion!
