The techniques I developed for studying turbulence, like weather, also apply to the stock market
Benoit MandelbrotI conceived, developed and applied in many areas a new geometry of nature, which finds order in chaotic shapes and processes. It grew without a name until 1975, when I coined a new word to denote it, fractal geometry, from the Latin word for irregular and broken up, fractus. Today you might say that, until fractal geometry became organized, my life had followed a fractal orbit.
Benoit MandelbrotSmooth shapes are very rare in the wild but extremely important in the ivory tower and the factory.
Benoit MandelbrotI'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.
