Einstein's best walking buddy in Princeton during his IAS years was Kurt Godel, another German refugee whose eponymous theorem represents one of the most original results in 20th century mathematics. Carly Simon wrote the original Godel song: "You're so vain, you probably think this song is about you." But after 30 years, it's worth another go. Sure, it would have been easy to throw in a line like "This song is not about Kurt Godel", but I don't do easy. So I went back to Jimmy van Heusen for the melody, and doctored the Sammy Cahn lyric (one of his better efforts, and that's saying something). No apologies necessary, as Sammy made a very good living doctoring other folks' lyrics. Like everything those guys wrote together, this song had rhymes which were tight and memorable, so it's a perfect vehicle for a parody.
