Swarm Intelligence

This Science Friday interview with Len Fisher, author of The Perfect Swarm, blew me away. Apparently it can be proven that (in the right domain) averaging a group of people's independant opinions is more likely to produce the best decision than asking any individual expert. Did I hear that right? I may have to read the book!

Dark Flow

The mathematics are beyond my understanding, but I still find the concepts of modern physics fascinating. If I understood this recent segment of Science Friday correctly, a phenomenon called dark flow may validate string theory. Wow!
