Halloween Math Lesson

Sorry for the week-long blackout.  I've been working on a few different things.  But rest assured... Enigmatic Meanderings will be back to its regularly scheduled programming beginning on Monday. For, today, though I have a special Halloween treat for you all (or is it a trick?).

I stumbled across this video.  It's of a math professor at Biola University named Matthew Weathers giving a special Halloween lesson.  It's pretty clever and funny.  All math professors should be this goofy.

Enjoy.
