If you have a hammer, use it everywhere you can, but I do not claim that everything is fractal.

Fractal geometry is not just a chapter of mathematics, but one that helps Everyman to see the same world differently.

Some mathematicians didn't even perceive of the possibility of a picture being helpful. To the contrary, I went into an orgy of looking at pictures by the hundreds; the machines became a little bit better.

For much of my life there was no place where the things I wanted to investigate were of interest to anyone.

Round about the accredited and orderly facts of every science there ever floats a sort of dustcloud of exceptional observations, of occurrences minute and irregular and seldom met with, which it always proves more easy to ignore than to attend to.
