Link: “I am a mathematician, and I would like to stand on your roof.”

Speaking of excellent talks, you should definitely watch this one. This is a look at African fractals, which are surprisingly ubiquitous throughout Africa, and which has some great conclusions, including:

1. The computer owes its creation to African fractal making (by way of Leibniz and Boole).

2. The answer to capitalist excess may be found in the self-organizing algorithms of African trade.

Also, there’s a clear story of how natural mathematics is to our story, as humans. This kind of pattern making springs out of the woodwork. This is a particularly cool example of it, though.
