The mathematician Benoit Mandelbrot has died. Here is the NY Times obituary.
Here's a lecture he gave at a TED conference in Feb 2010:
I remember attending a lecture of his at the University of British Columbia in the 1980s. What I remember most was his enthusiasm and his curious and interesting examples from his mathematics.
Update 2010oct17: Here is an article Remembering Benoit Mandelbrot by the mathematician Rudy Rucker. It is a reminiscence of going to Mandelbrot's house in 2001 to talk about helping put together an IMAX film on fractals. It has some nice graphics and a video clip touring a quintic Mandelbrot set.
