My friend Herrick Goldman posted this on the stagecraft mailing list.

“In a world where politics asks “why teach critical thinking?” we have this video series, which reminds me of a lighting lecture mr. Parker does… Enjoy And watch the rest of her stuff..”

So, I had to watch. Great video…

Anti-parabola propoganda, plus musing on math class, cardioids, connect the dots, envelopes of lines, even a bit of origami.

Go ahead and click the video. It should start even though it looks like it’s set to private.
