Origins: Antarctica:  Antarctica Fractals with Benoit Mandelbrot (Webcast)
Running Time:
0:46:48
In 1963 Benoit Mandelbrot introduced the fractal concept. Fractals are shapes or behaviors that have similar properties at all levels of magnification. Just as the sphere is a concept that unites raindrops, basketballs and Mars, so fractal is a concept that unites clouds, coastlines, plants and strange attractors. Dr. Mandelbrot dropped in for a visit during our 2001 series of webcasts about Antarctica. We took some time out from the freezing cold to interview him.
