Here are a few of my favorites among the 37 different criteria that Baez lists.
Of course, if your life's work scores high on the index, you're probably not laughing. Baez mentions one such example named Ludwig Plutonium, who's since changed his name (again) to Archimedes Plutonium. Mr. Plutonium posits, among other things, that the universe we live in is one giant plutonium atom. Oh, and his awesome nickname? "The King of Science." I'm guessing that's self-appointed.
Certainly there's middle ground to be found here somewhere between the tin-foil wearing crackpots and the legitimate scientists who conduct potentially life-saving and world-changing research. I don't think anyone would argue with that. Indeed science's history is replete with examples. So does anyone have a favorite you'd like to nominate, um, other than yourself?
