African fractals: Ron Eglash on TED. “I am a mathematician, and I would like to stand on your roof.”
This is how Ron Eglash greeted many African families while researching the intriguing fractal patterns he noticed in villages across the continent. He talks about his work exploring the rigorous fractal math underpinning African architecture, art and even hair braiding — and his cool math tools for students. (Recorded June 2007 in Arusha, Tanzania. Duration: 16:51.) Watch Ron Eglash’s talk on TED.com, where you can download it, rate it, comment on it and find other talks and performances.
