Let’s go to the carnival

The 52nd Carnival of Mathematics is underway over at The Number Warrior. I’m glad it was resurrected. Check it out!

Two other mathematical tidbits.

Clue in yesterday’s NY Times crossword: Calculus pioneer.
The answer: EULER.

Also in today’s NY Times, the headline: U.S. Jobless Rate Hits 8.9%, but Pace of Losses Eases. When I first saw this I thought third derivative! The rate of change of a rate is decreasing. However, upon further reflection, I realized that the unemployment rate is not really a rate of change in the calclulus sense—and is definitely not a time derivative—so the statement is only a second derivative. Oh, well.

(Contrast this with Richard Nixon’s use of the third derivative).
