Dr. Shapiro's Puzzle of the Day

Today's Puzzle

Friday, April 30
Galaktoboureko, pictured here, sounds like a dessert that's out of this world—but it's actually just from Greece. Show that it's not all Greek to you by telling me which ingredient(s) can be inferred from the name of this sweet treat.

Yesterday's Puzzle + Solution

Today's puzzle combines geography and linguistics!

Seen at left is a Russian map of the Bay Area. The place names are written using the Cyrillic alphabet, while preserving the sound of the English name as much as possible. I have circled five cities. Can you identify them?

Tip: Use the places you recognize to figure out the sounds of the letters. But beware:

Solution Clockwise around the bay, from the top: Pittsburg, Walnut Creek, Hayward, Sunnyvale (not San Niveil!), Half Moon Bay.

I got lots of great responses! Peter sent me a letter-by-letter account of how he solved this, while Charlie pointed me to an article about Soviet maps. Mr. Gregg, noticing the absence of the Carquinez and Richmond–San Rafael bridges, tried to figure out how old the map is; however, the Carquinez Bridge opened in 1927, so its omission seems likely to be an error. But there are clues that the map is pretty old, if not that old. San Jose (САН-ХОСЕ, cut off at lower right) gets a barely bigger font size than Berkeley, and Port Chicago, a town destroyed in 1968 possibly in an attempt to solve this puzzle, can be seen just north of Pittsburg.

A few of you noticed that Cyrillic letters resemble not only the Roman alphabet, but Greek as well; Р makes an 'r' sound like Greek rho, and Ф, Г, П, Л, Д also resemble their Greek sound-alikes. But if you aren't one of the four solvers who can read Cyrillic, good luck accounting for Ь.

Congratulations to yesterday's solvers Peter V., Jacob C., Arina, Ena, Jackson, Anna K., Atticus, Charlie, Yana, Zane, Connor, Mr. Gregg, and Graham. 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.
