Mr. Mandelbrot:
Benoit B. Mandelbrot (20 November 1924 – 14 October 2010) was a Polish-born French-American mathematician and polymath with broad interests in the practical sciences, especially regarding what he labeled as "the art of roughness" of physical phenomena and "the uncontrolled element in life". He referred to himself as a "fractalist" and is recognized for his contribution to the field of fractal geometry, which included ....
Mandelbrot Set:
The Mandelbrot set (/ˈmændəlbrɒt/) is the set of complex numbers c for which the function fc(z)=z^{2}+c does not diverge to infinity when iterated from z=0, i.e., for which the sequence fc(0), fc(fc(0)), etc., remains bounded in absolute value. Its definition is credited to Adrien Douady who named it in tribute to the mathematician Benoit Mandelbrot, a pioneer of fractal geometry.
