Conics

This is really cool! Circles, ellipses, parabola, hyperbola can all be taken out of a double cone. Observe the link:

Math at MacPhail

Every Thursday I do math from the MacPhail Center for Music. It's interesting to work on math problems and listen to trumpets warming up in the background. Currently, I'm listening to a piano player practicing the Suzuki song "Lightly Row".

(That was a while ago. Because MacPhail is a school, they've got some sort of filter on their wireless so I couldn't post while I was there. Now I'm home, it's late, I just fenced my first high school meet, and my knee hurts)
