From Random Polygon to Ellipse

matthen:

Draw some random points on a piece of paper and join them up to make a random polygon. Find all the midpoints and connecting them up to give a new shape, and repeat. The resulting shape will get smaller and smaller, and will tend towards an ellipse!  [code] [more] [bigger version]

Dear Unthinkable Mind Class,
This looks like a picture of how a cohesive idea slowly makes itself present. It reminds me of how memories prompted by any random word will always generate a story once we focus on them.

I filled at least half a dozen notebook pages on a plane recently trying to recreate this. Maybe the best illustration of how a book or a project comes together, too…

DONALD IN MATHMAGIC LAND





A 1957 27-minute Disney Animation about Mathematics that was nominated for an academy award, and a fantastic example of using animation to explore educational concepts… I remembered this from elementary school: especially the part where he uses angles to play pool. John Medina, in his book BRAIN RULES, credits this movie with starting his career in science.
