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).

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
What do you think about Donald Trump’s use of language? A lot of people criticize it. On the other side there were even people who criticized Obama’s language, so where does the truth lie? Frances Brown, who worked for the… Read More ›

Comic Sans is back in the news.
Oh nos, Comic Sans is back in the news! Three times in the past 20 years I’ve felt compelled to write about the Comic Sans font: in 2005, 2009, and 2016. And here we go again: Of all the things… Read More ›

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 ›

White privilege and male privilege are alive and well in the Hugo awards, despite claims about “criminally overlooked” white males. All you have to do is look through the inestimable Jo Walton’s deeply annotated objective account of all the Hugo awards… Read More ›

Do we need to upgrade the Constitution? Plus a parsing problem…
According to my iPhone (see screen shot below), we can do so for only $1.99! Any suggestions? Also, we have this quotation from a Washington Post article: The whistleblower is not white,” one 4chan commenter asserted Thursday, probably misreading a… Read More ›

Greek Script Hacking

Diversity and majorities in Boston elections
Boston just had a preliminary election yesterday (more or less what other places call a primary, though it’s non-partisan). As you know from my post of September 22, one of the topics that I teach in my Quantitative Reasoning class is… Read More ›

Batman uses linguistics! Who’d’a thunk it?
Yes, it’s a couple of days late for Batman Day — but that’s OK. I was astonished to learn that there are not just one but two episodes of School of Batman in which linguistics plays a major role. First… Read More ›

Looking back from the 23rd Century
It’s too had that the Times editors had to write “The opinion piece below is a work of fiction,” but I guess nobody recognizes satire anymore. If they had managed to date it “September 23, 2021,” I don’t suppose anyone… Read More ›
