If You Have A Hammer,

I've Been A Professor Of Mathematics At Harvard And At Yale. At Yale For A Long Time. But I'm Not A Mathematician Only. I'm A Professor Of Physics, Of Economics, A Long List. Each Element Of This List Is Normal. The Combination Of These Elements Is Very Rare At Best.

A Fractal Is A Mathematical Set Or Concrete Object That Is Irregular Or Fragmented At All Scales...

Smooth Shapes Are Very Rare In The Wild But Extremely Important In The Ivory Tower And The Factory.

One Of The High Points Of My Life Was When I Suddenly Realized That This Dream I Had In My Late Adolescence Of Combining Pure Mathematics, Very Pure Mathematics With Very Hard Things Which Had Been Long A Nuisance To Scientists And To Engineers, That This Combination Was Possible And I Put Together This New Geometry Of Nature, The Fractal Geometry Of Nature.

Now That I Near 80, I Realize With Wistful Pleasure That On Many Occasions I Was 10, 20, 40, Even 50 Years Ahead Of My Time.
