Here we are, 10-plus months into the year, and we have nothing to show for it. At least, that is the case if we measure our progress by the gains (or losses) of the Dow Jones Industrial Average.

IBM and http://IBMblr.Tumblr.com celebrate the life of Benoit B. Mandelbrot, IBM Fellow Emeritus and Fractal Pioneer. In this final interview shot by filmmaker Erol Morris, Mandelbrot shares his love for mathematics and how it led him to his wondrous discovery of fractals.
