Both chaos theory and fractal have had contacts in the past when they are both impossible to develop and in a certain sense not ready to be developed.

There is a saying that every nice piece of work needs the right person in the right place at the right time.

Beautiful, damn hard, increasingly useful. That's fractals.

Regular geometry, the geometry of Euclid, is concerned with shapes which are smooth, except perhaps for corners and lines, special lines which are singularities, but some shapes in nature are so complicated that they are equally complicated at the big scale and come closer and closer and they don't become any less complicated.

There are very complex shapes which would be the same from close by and far away.

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

I spent half my life, roughly speaking, doing the study of nature in many aspects and half of my life studying completely artificial shapes. And the two are extraordinarily close; in one way both are fractal.
