Speaking of Einstein--have you ever wanted to explain the world on a napkin? The Edge, self-described as "an online collective of deep thinkers," has teamed up with the Serpentine Gallery in London to participate in a month-long Experiment Marathon. The Serpentine has been asking leading scientists and thinkers "What Is Your Formula?" and the Edge is now hosting the fascinating answers on their site. Rickard Dawkins, Brian Eno and Benoit Mandelbrot are just a few of the contributors.
