A lot of people think it’s strange that a scientist would become a comedian. I don’t think that’s strange. I think it’d be weird if someone went the other way. Hey did you hear whose running Los Alamos Nuclear Laboratory? Larry The Cable Guy! My that is surprising. But I have found a way to combind the comedy with the Ph.D. Chaos One of the tools we have for understanding and analyzing a chaotic system is the final state diagram. Some of you will recognize this as the final state diagram for the nondimensionalized form of the logistic equation. Some of you will not. It’s easy enough to understand if we replace this cryptic variable r with something a little more tangible. This is a drinkers final state vs the number of drinks they’ve had. If everone in your party limits themselves to three drinks, pretty much everyone ends up in a reasonable state. As those reasonable people continue to drink they split into two groups. As the happy group continues to drink they split once again. Effective Population Size A concept intoduced by an American geneticist by the name of Sewall Wright. The idea here is that even though a population may appear to be quite large. In terms of it’s breeding potential it can actually be very small. I see this every time I go to a party looking for a date. At first glance it looks like there’s a large population to choose from, but since I’m a straight guy I immediately eliminate all the men. Then all the women that are out of my league. All the women that are beneath my standards. Anyone that already has a boyfriend. Eh, who am I kidding? I have to eliminate anyone who’s already been traumatized by Charlie Sheen.
