Unless you are a circuit engineer, where in daily life are you most likely to encounter the number 4011?
Hint
I'm sure you've seen it before; the question is, did the information stick?
I recently heard about a magazine for puzzle aficionados called Puzzles & Answers. Can you figure out what animal appears in this magazine's logo?
Hint #1
The choice of animal is based on a certain way to abbreviate the magazine's name.
Hint #2
The same animal appears in the much more famous logo of an international organization. It is said that they chose this logo because it would look good on an cheaply printed pamphlet.
Solution
It's a panda (for Puzzles and Answers, naturally).
The second hint referred to the logo of the World Wide Fund for Nature (formerly the World Wrestling Federation, uh, World Wildlife Fund). That logo referred to a specific panda in the London Zoo, but it was a nice bonus that it could be printed in black and white.

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.
