Vi Hart Is Amazing
I first noticed her with one of her “Doodling in Math Class” videos (I think this one: Connecting Dots), but then, since I’ve been into Flexagons since my 7th grade math teacher taught us about them back in 1972 (thank you Mr. Woodworth!) I started following her with her flexagon series with the first one, Hexaflexagons.
This one is particularly thought provoking: Pi Is Still Wrong.
Just thought I should share.
