I Luv Vi Hart

Perhaps you heard of the blog phenom named Vi Hart, who posts mathematically intriguing videos about geometric shapes, number theory and the like. ┬áIt’s always a hands-on experience for sure, but she often includes references to historical figures, such as Blaise Pascal, or in the case of the following video, Richard Feynman.

You can see the first part of her video summary of hexaflexagons here.
