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).

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 ›

We all love long words.
We all love impressively long words, don’t we? We especially love words from languages like German and Turkish, which are known for harboring such beasts —like Donaudampfschiffahrtsgesellschaftskapitän and muvaffakiyetsizleştiricileştiriveremeyebileceklerimizdenmişsinizcesine. 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 ›
