I am saddened to hear that Benoît Mandelbrot has passed away. His The Fractal Geometry of Nature excited and intrigued me when I was in high school, though I admit that while I, like many others, examined all the pictures, I read only scattered parts of the text. The talk of his I attended as an undergraduate was the first technical talk by a famous mathematician that I understood, essentially, in full. The popularity of fractals was due to the gorgeous pictures, and was aided by the simplicity of some of the underlying mathematics, which made it accessible to so many, and to the connection of fractals to so many phenomena. That fractals appeared at all scales in nature, from galaxies, to coastlines, to trees, I knew from looking at his book, but their tie to economics was new to me. He struck me as arrogant, but in an endearing way since his pride in his contributions stemmed from his intense love of the work and his absolute conviction of its importance. He clearly enjoyed his maverick status as someone who worked in a different way than most mathematicians, and on non-standard mathematics. Although he taught us to look for self-similar patterns throughout the universe, we won’t find the like of him any time soon.
