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).

Maybe You Should Talk to Someone: A Therapist, Her Therapist, and Our Lives Revealed
Mixed feelings about this non-fiction book. Maybe I should talk to someone about it. On the one hand, it’s filled with fascinating stories and views — things that make the reader close the book in order to stop and think… Read More ›

Stories and courses
What is a course? Is it a collection of chapters? Is it a collection of topics? I hope it’s neither — especially not that collection of chapters! A course should always tell a story. It should have a unifying purpose…. Read More ›

Stories and tests
Should a math test tell a story? That’s certainly not what most people think a math test should do! Should a course tell a story? More on that tomorrow, but at least I might get a few more takers for… Read More ›

Weston alum on treating depression
One of my former Weston students has just published “Treating depression takes much more than serotonin,” a fascinating article in Popular Science. The author, Grace Huckins, class of 2012 and erstwhile co-captain of the award-winning Weston High School Math Team, has written this… Read More ›

Greek to Me
The best book of the year! Yes, I know that the year is only half over, but I’m still going to nominate Mary Norris’s Greek to Me as the best book of the year. Equal parts travelogue, memoir, mythology, and… Read More ›

Machines Like Me
What? Ian McEwan writes science fiction? News to me, but I had to give this book a chance. It’s Ian McEwan, after all. Machines Like Me falls into the alternative-history subgenre, in which the author postulates that one or more… Read More ›

Bella Luna
It may not look like much in the picture, but it sure was yummy: grilled sea scallops with fresh corn, cherry tomatoes, and peaches (that’s a peach, not an egg yolk, in the picture), all served over parsnip puree. This… Read More ›

Virginia Woolf: “On Not Knowing Greek”
What did I know about Virginia Woolf? Not much. I knew that she wrote about needing “a room of her own,” and that she had written something about a lighthouse, and I had long ago seen Edward Albee’s Who’s Afraid… Read More ›

The most commonly spoken language in your state
What’s the most commonly spoken language in your state? (We’ll exclude the two obvious ones, of course — English and Spanish.) This map shows the surprising answer, at least if we trust Business Insider: Absolutely fascinating, but I’m not completely… Read More ›

Barcelona (the restaurant, not the city)
Four out of five stars, IMHO, for the Barcelona restaurant in Brookline. Barbara and I went there last night as a change of pace for our anniversary dinner. A major motivator was that we both love Barcelona, the city, and… Read More ›

“Why Chinese is so damn hard”
I just read a provocative essay by David Moser entitled “Why Chinese is so damn hard.” Is it really that hard? And are we talking about speaking Chinese or reading it? Hard compared to what? Hard for a foreigner or… Read More ›

Not a very large fraction of the whole world
By the way, MapLoco, someone should tell you that Puerto Rico is part of the United States and not a separate country, no what what Donald Trump thinks. Other than that (and a couple of other similar gaffes), this is… Read More ›

Yellow Door Taqueria
Barbara and I had an excellent dinner last night at Dorchester’s Yellow Door Taqueria, easily found by looking for… of course… the yellow door. I know that many people consider this a bar rather than a restaurant, but it’s successfully… Read More ›

Untranslatable words
One of the first things any article about sisu will tell you is that this Finnish word is untranslatable. (https://finland.fi/arts-culture/sisu-within-finnish-key-life-love-success/) ‘Sisu’ in Finnish means strength, perseverance in a task that for some may seem crazy to undertake, almost hopeless. (http://www.bbc.com/capital/story/20180502-sisu-the-finnish-art-of-inner-strength)… Read More ›

Teacher comments by race of student
Hmmm… Math teacher Bowman Dickson has gathered some statistics on the frequencies of various words used by teachers of various subjects in their report-card comments on high-school students. Here’s one of his charts: The phrase “more common” in the data above… Read More ›

Andrew Yang
It’s too bad he isn’t a very plausible candidate: look at that hat! (If you don’t recognize him, that’s Democratic candidate for president Andrew Yang.)

Those reviewers on Amazon are ____________ [fill in the blank]
As Tom Lehrer famously said, “the reason most reviews on Amazon are so atrocious is that they were written by the people.” Actually, that’s not quite what he said. He actually said “the reason most folk songs are so atrocious is… Read More ›

Babel
Read and enjoy this book! Don’t argue: just do it. You’ll learn a lot and will have fun along the way. As the subtitle to Babel — Around the World in Twenty Languages — suggests, Dutch linguist Gaston Dorren takes us… Read More ›

What kind of lies does he-who-shall-not-be-named tell? Bald-faced or bold-faced?
“I’m starving! I haven’t been fed in days!” says William. “Just look at that face!” That’s a typical cat lie. But is it a bald-faced lie? Or even a bold-faced lie? When I was a kid, interested in both language… Read More ›

Tones, Hmong, sounds, and spelling
The Hmong are a well-known ethnic group, right? Well, not exactly. They’re probably not well-known to you, unless you are particularly interested in southeast Asia or happen to live in Minneapolis or Fresno, even though there are about 15 million… Read More ›
