Link of the day: "When is a Googol not enough?"

Wati Taylor (an MIT string theorist) gave an awesome talk at Google about why there may be as many as 10^1000 possible solutions to describe the physical universe and how it might be possible to narrow down the possibilities using search algorithms. I really like how his talk is straightforward, clear, and concise. It's neat how string theory, cosmology, and algorithms come together in this problem.
