The middle day of the days counted, so one week of news cannot move it. The line under it is the last 390 days, one point a day.
Something wrong?He coined the word "fractal" and showed that clouds, coastlines, and market crashes share hidden geometries - patterns lurking in what everyone else dismissed as chaos.

For most of my life, one of the persons most baffled by my own work was myself.
Engineering is too important to wait for science.
If you have a hammer, use it everywhere you can, but I do not claim that everything is fractal.

About this person
Mandelbrot fled Warsaw with his family in 1936 at eleven, landed in France, and after the war studied mathematics in Paris and aeronautics at Caltech. In 1958 he joined IBM for what became a 35-year run, where access to early computers let him do what no one had before: render fractal images and discover the Mandelbrot set in 1979-1980. He called himself a "fractalist," chasing "the art of roughness" across cotton futures, shorelines, and a dozen other fields - statistical physics, hydrology, linguistics, chaos theory - proving that visual complexity springs from simple rules. He taught economics at Harvard on sabbatical, then landed at Yale late in life as a Sterling Professor, the oldest in the university's history to receive tenure. He died in 2010; his autobiography came out two years later.
