Benoit Mandelbrot

"Clouds are not spheres, mountains are not cones, coastlines are not circles, and bark is not smooth, nor does lightning travel in a straight line."

"Bottomless wonders spring from simple rules, which are repeated without end."

"A fractal is a way of seeing infinity."

"The Mandelbrot set is the most complex object in mathematics."

"Smooth shapes are very rare in the wild but extremely important in the ivory tower and the factory."
