Sometimes, declaring a problem impossible
is a great advance.
~ Benoit B. Mandelbrot
Heralded as the "Father of Fractal Geometry", Benoit Mandelbrot (1924-2010) was interviewed about his work by Errol Morris. This wonderful and touching video of Morris's profile introduces us to the extraordinary mathematician, who relates his gift for math and his fascinating discovery of fractals. That discovery has produced enormous benefits for science, medicine, telecommunications, and many other disciplines.
