Dear Dr. Boli: There was supposed to be a blue moon tonight, but when I looked at it it was the same grubby white color it always is. Why isn’t it blue, and what can be done about it? —Sincerely, An Astronomer Who Prefers to Remain Anonymous.

Dear Sir or Madam: The moon is not blue because it is impossible to feel sad when such exciting discoveries are coming in from Pluto. The celestial bodies exhibit an exemplary emotional solidarity, and we could learn much from them. If you still have complaints, however, you may refer them to Mr. Lorenz Hart and see where that gets you.
