Don't fret this Sunday if you're standing alone. Without a dream in your heart. Without a love of your own. After all, on Jan. 31 we'll have a blue moon. And we all know what that means.
Science now considers a blue moon to be the second full moon in one month.
But when Broadway legends Richard Rodgers and Lorenz Hart wrote their 1934 classic, a blue moon had no astronomical meaning. Nor did some sentimental scientist later pay homage to the song by attaching it to his or her work. It was neither an artist nor a politician who redefined blue moon. It was a board game. In the 1986 Genus II edition of Trivial Pursuit, the game makers printed a blue moon question and the world was never the same.
