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).

“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 ›

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 ›

Doing Justice
We all know that justice is blind. “And deaf and dumb,” many a commentator has added. But what is justice, and how do we ensure that it is done? Please don’t get your knowledge of our justice system from television! Read Doing Justice: A Prosecutor’s… Read More ›

Rationality vs. Intelligence
What do IQ tests measure? Intelligence? Something else? Some of us think they measure how well you do on IQ tests… …and nothing else. Is that the same as intelligence? And how does intelligence differ from rationality? Read this article,… Read More ›

Computer Lib
What? A popular book about computers was published in 1974? “How is that even possible????” you ask. Computer Lib, by Ted Nelson, was indeed published in 1974, way before the World Wide Web, and it is undeniably and explicitly a popular… Read More ›

An outstanding vocal recital by a Weston student
Five years from now, when she’s nationally known, I’ll be able to say “I knew her when.” Yesterday I had the privilege of attending an outstanding vocal recital by Weston junior Kayla Silverman, one of my former geometry students. For… Read More ›

Is it even possible to have an intergenerational dialogue? Is that really what we had on Wednesday?
So, finally, it’s Wednesday, the last day of the reunion. (Well, the last day for me. I just don’t have the stamina to go to the afternoon session today or to hear Angela Merkel tomorrow.) Today’s symposium is an “intergenerational… Read More ›

Do we have fair elections? Can we? Do we have equal representation? Can we?
Continuing with my 50th reunion, check out this map of Pennsylvania’s second Congressional district, which is actually not the most gerrymandered in the country, although it’s in the running. It illustrates what I had expected when I decided to go… Read More ›

Still more about the reunion. (Will it ever end? Yes, it really will… but not yet.)
“True-blue American Yalie George Bush versus pinko-Crimson Harvard Mike Dukakis.” That‘s what some Republicans were saying back in 1988 when George H.W. Bush was running against Michael Dukakis. The color prejudices are understandable, and maybe even the college prejudices, but… Read More ›

“We were going to change the world. What went wrong?”
Not everything went wrong. In many ways we did change the world. Continuing to describe my 50th reunion of the Harvard Class, let’s move on to a Tuesday symposium titled “We were going to change the world. What went right?… Read More ›

“Vote early and often,” he said; “support whoever the Democratic nominee is.”
No, it wasn’t a political rally. It was a reunion: the 50th reunion of the Harvard Class of 1969. One speaker, Bob Hughes, exemplified a running theme of the entire reunion by pointing out what we can do: “Vote early… Read More ›

Vietnam War legacy, Al Gore, and more: The first 24 hours of the reunion
Exhausting and overwhelming! That’s what the first day of my 50th Reunion was like. Not so much for the usual reason that exhausts and overwhelms us introverts — too many people — but because of the intensity of the experiences… Read More ›
