In 2018 I semi-retired by retiring from Weston High School after my 21st year teaching mathematics there. This was also my 44th year as a teacher altogether. In 2023 I retired fully, adding in my 18 years at Harvard’s Crimson Summer Academy each summer. For 21 years I had taught at the Saturday Course in Milton, MA, and I used to serve on the board of the Dorchester Historical Society.
I read, cook, and spend a lot of time building my model railroad. For some reason I’m left with less free time than would be ideal, considering that I’m supposed to be retired, but somehow I also manage to devote time to my wife, Barbara, and to our varying number of cats (once up to six, but now sadly down to one).

Translation and culture
Translation is impossible. Traduttore, traditore. That’s the lovely word pairing in Italian — roughly “a translator is a traitor”, where there’s only a small vowel change and a doubled consonant distinguishing the two words. A recent article by Matthew Reynolds explored… Read More ›

The bathroom is finally finished!
It took nine weeks. First the workmen demolished everything, down to the studs. Then they built a complete new bathroom in the same space. Some fixtures from Kohler and Home Despot, but primarily from our local Norfolk Hardware and Home Center. (Shout-out… Read More ›

Intertwingled/“Hypertext in the Age of Trump”
Hypertext pioneer Mark Bernstein has just published Intertwingled, a collection of nine essays and one short story. No one could ever say that Bernstein is shy about expressing his opinions, so don’t expect some dry attempt at scientific “neutrality.” If you… Read More ›

Graphing calculator prices: how TI cornered the market
You’re a student. Why are you required to buy a Texas Instruments calculator? Why not something cheaper and better? Usually what you’re buying is a TI-84, a 15-year-old piece of expensive technology. Zachary Crockett explains how we got into this… Read More ›

224 Boston Street
As I wrote on 12/12/2015 and 10/31/2010, Dorchester used to have a scarcity of good restaurants, but now there are a lot: Twenty-five years ago you could count the number of good restaurants in Dorchester on the fingers of one… Read More ›

Blue, green, and grue
Color names are a mystery. At least to me. Take a look at the color chips in the image. If we limit ourselves to common English color names (excluding, that is, the myriad of names used by both types of… Read More ›

Trump’s language — and Obama’s

Linguistics in MetroWest
For many years I inserted linguistic lagniappes into my honors geometry classes at Weston — typically for 15–20 minutes, twice a month. You may wonder what the connection between linguistics and geometry might be — but if you view honors geometry as… Read More ›

“America’s math curriculum doesn’t add up,” observes Steve Levitt.
Please listen to (or read) this week’s Freakonomics podcast. I will wait. No, actually, I’m going to discuss it without making any prior assumptions that you have listened to it or read it: If you’ve been reading this blog for… Read More ›

Neal Stephenson’s Fall
Another thousand-page tome from the wonderful Neal Stephenson! Well, no, it’s actually only 880 pages — but that’s close enough. It’s still worth every minute (or should I say “every day”?) that it takes to read it. Basically, Fall: Dodge… Read More ›

Greek Script Hacking
