Dr. Shapiro's Puzzle of the Day

Today's Puzzle

Thursday, January 28
Today, a few random questions about calligraphy:
  1.    Where is this famous W from?
  2.    Calligraphic letters are not always intuitive. Can you tell what letter this is? (You may see it in an advanced math textbook.)
  3. This bird elegantly embodies a phrase from what religion?

Yesterday's Puzzle + Solution

My sister and I both have beef with Amazon (the company, not the river). I have a minor beef because Amazon appropriated my initials, AWS, for Amazon Web Services. My sister has a major beef. What is her name?

Hint Look, if you know what's good for you, turn on the lights yourself.

Solution My sister's name is Alexa. (We're all A's in my family.)

Here's a list of things not to say around her.

Congratulations to yesterday's solvers Leo S., Jacob C., Yana, Charlie, Anna J., Hazel, Maddy, and the Greggs. Thanks to everybody who made a guess!

About This Site

Though he now teaches mathematics, Dr. (né Mr.) Shapiro's first job in a K–12 school was as a lunch monitor in Davis, CA. It was there that he originated the Puzzle of the Day, even rewarding correct answers with tickets in denominations like "15 points" (though without a clear idea of how he'd ultimately redeem these). Dr. Shapiro's favorite puzzle from this pre-professional era was "Tell me the location of the beehive on this campus."

Ten years later, Dr. Shapiro revived Puzzle of the Day at Proof School, writing each day's puzzle on a name tag. After 600 puzzles or so, he was just starting to feel normal about students reading his chest all the time when campus closed and the puzzle, like the rest of our lives, moved online. New puzzles are posted daily on school days.
