Party conversation tonight turned from:

• a particular child's personal certainty
• to mathematical certainty
• to number theory
• to Paul Erdös
• to Erdös numbers
• to six degrees of Kevin Bacon
• to the fact that Burgess Meredith is the most connected actor (I was wrong: Rod Steiger is the most connected)
• to how campy the old Batman TV series was.

BTW: Malcolm Gladwell wrote a great article about connections among people for the New Yorker a few years back: Six Degrees of Lois Weisberg.
