I used this song about this time last year. “P.S. I Love You” was published in 1934. The music was written by Gordon Jenkins, the lyrics by Johnny Mercer. It's been recorded by artists such as Billie Holiday, Rudy Vallee, Bette Midler, Frank Sinatra and many others.
Last year, I asked if anyone knew how this song could be connected to Pi but got no replies, so I thought I'd try again. I'll admit it's a bit of a stretch but it's there. Besides, have you ever tried to find a snail mail song that could in some way be related to Pi? So, as irrational (heh-heh, math humor) as it may seem, I ask again, what could this song have to do with the number Pi? Oh, and here's a clue this time: It has something to do with the lyrics. Let me know what you come up with and Happy Pi Day!
