Benoit B. Mandelbrot was a Polish-born, French and American mathematician, noted for his work on the “theory of roughness” and the development of the field of fractal geometry. His other work include creation of the so-called Mandelbrot set of never-ending fractal shapes and work on the mathematics of the stock market prices.
In this talk, which happens to be one of the last public appearances of the famous mathematician, Mandelbrot talks about his work on fractals and other fields. Mandelbrot present his ideas, that were first presented in TED of 1984, on the complexity of roughness and the use of fractal mathematics.
