Halmos Square

Quick side note: You know the little square that replaces the "q.e.d." at the end of proofs? It's called the Halmos Square.

There was a guy named Halmos (University of Indiana, maybe?) who came up with the idea. You know what it represents? A TOMBSTONE. It is meant to say that "the proof is dead." Or "that kills the proof."

I'm dead serious. Really.
