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).

But those are not particularly natural words in German and Turkish respectively,… Read More ›

Tolkien, the movie
The new biopic, Tolkien, was clearly written for me. But you’ll enjoy it too. What, you may wonder, do I mean by claiming that it was written for me? Of course that is not literally true: the film-makers don’t know… Read More ›

How many ml in a liter?
So I’m in a certain store in Jamaica Plain today — name kept anonymous to protect the oh-so-innocent — and I ask the clerk if they sell Hennessy Privilege (a cognac, for those of you who don’t know). She says… Read More ›

High School SCOTUS
Can high-school students conduct an excellent interview and write an excellent article about it? Anna Salvatore and Joe Hanlon certainly can! No, I have never taught these two. I have never even met them. But I highly recommend Anna’s blog, High… Read More ›

The Odd Clauses
As you know, the President of the United States takes an oath to “preserve, protect and defend the Constitution of the United States.” And of course our current president does that faithfully — right? — but not everyone is familiar with… Read More ›

“Math teachers should be more like football coaches.”
As you probably know, John Urschel is both a professional mathematician (at MIT, no less) and a recently retired professional football player (in the NFL, of course — recently retired from the Baltimore Ravens). What a combination! A few days… Read More ›

Arabic numerals? Oh, no!
Did you hear that they’re teaching Arabic numerals in public schools? I’m shocked, shocked. In America, no less! What is this world coming to? A recent poll showed that 56% of Americans don’t want public schools to teach Arabic numerals…. Read More ›

Why do Americans think that Asians mix up R and L?
Speaking of Asia, why do so many Americans think that Asians mix up R and L? (Asians? East Asians? Chinese and Japanese? How far does this stereotype go?) Before we answer this question, I need to point out a more… Read More ›

Back from New York, Part 2: The High Line
On May Day I wrote about the Tolkien exhibit and promised to discuss the rest of our NYC trip in my “next post.” Unfortunately that task turned out to be far too big for one post, so it is being split among… Read More ›

The Silk Road, the Noodle Road, and Confucius
