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).

Five ways to engage reluctant learners
One of my favorite bloggers, John Spencer, wrote a post a year ago on how to engage reluctant learners. But let me first quote the hook, his opening paragraphs: I am currently on my fifth solid day of doing things that… Read More ›

Snow Crash
The time came to re-read Snow Crash. I had first read Neal Stephenson’s seminal science fiction novel when it came out in 1992, and then again at the end of the millennium, which seemed appropriate. Now, to celebrate its 25th… Read More ›

In the last year or two the southern part of Dorchester has been blessed with a large influx of new restaurants. Here are some capsule comments on ten of them (yes, ten! — and there are more) in alphabetical order:… Read More ›

The Industry
“The Industry”? Is that a restaurant? Yes, indeed; it’s Dorchester’s newest restaurant. Barbara and I decided to try it out last night. All in all — two thumbs up. Fortunately they have valet parking (in the gas station across the… Read More ›

PhDeath: The Puzzler Murders
How could I resist? Word puzzles, a murder at NYU, some math, a dash of ancient Greek, political intrigue, faculty politics, philosophy, social commentary, and even Will Shortz… obviously irresistible. So I didn’t resist it. The result of all these… Read More ›

3D pens?
Who’d a thunk it? Is there really such a thing as a 3D pen? Can you really write in the air? It all sounds very science-fictional. But 40 years ago 3D printers seemed science-fictional, and yet they were invented soon… Read More ›

Whence significant figures?
Significant digits can arise out of less significant data, right? For instance, you probably learned in ninth-grade science that a number rounded to one significant figure can be magically turned into one with three significant figures simply by changing measurement… Read More ›

Kids today
“What’s the matter with kids today? Why can’t they be like we were, perfect in every way?” OK, that’s satire. But I’ve heard plenty of teachers say, in all seriousness, “Why don’t students read instructions anymore?” Or, in a tone… Read More ›

East Side Story
An oxymoron? East Side Story is a fascinating 1997 documentary about musical comedy from the Soviet bloc from the 1930s, ’40s, ’50s, and ’60s! OK, it does sound like an oxymoron. But it turns out that it isn’t. This German documentary starts… Read More ›

The wrong way to order steak
“Properly” is the answer my friend Meredith always gives when a server asks “How would you like your steak cooked?” Or your pork. Or your salmon. Steak is supposed to be rare. Pork and salmon are supposed to be medium-rare…. Read More ›

4 3 2 1
As soon as I first heard about it, I knew that I had to read Paul Auster’s apparently semi-autobiographical novel 4 3 2 1: not only did the author grow up as a secular Jew from suburban Essex County, New Jersey,… Read More ›

June Academy: Egyptian Hieroglyphics

June Academy
Usually a school year ends with final exams — at Weston and elsewhere. As we know, final exams are designed to reduce stress and pressure by providing a relaxing time when classroom temperatures are over 90°. Right? No? You say… Read More ›

Cinquecento
You were probably thinking of 16th-Century Italy when you heard the word Cinquecento, right? That was my first thought too. Italy, yes, but in this context it’s an Italian restaurant in the South End of Boston, appropriately labeled an “authentic… Read More ›
