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).

  • Restaurants in the southern part of Dorchester

    By on

    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

    By on

    “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

    By on

    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 ›

  • Peer tutoring

    Who likes peer tutoring? Google “peer tutoring” and you’ll see dozens of upbeat images like this one. The Math Curmudgeon, who usually hits the nail on the head, certainly hits the nail on the head in the opening to his… Read More ›

    I have to share this cartoon (by Arnold Zwicky), but I’m not going to explain it:

  • 3D pens?

    By on

    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?

    By on

    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 ›

  • Chinatown or Mission Hill?

    By on

    Every year, the rising high-school sophomores at the Crimson Summer Academy take a field trip to a Boston neighborhood as part of their Quantitative Reasoning class. “What,” you may ask, “does a field trip to a neighborhood have to do… Read More ›

  • Kids today

    By on

    “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

    By on

    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

    By on

    “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

    By on

    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: Create Your Own Country

    By on

    For the second week of June Academy, my colleague Mary Fierabend and I co-taught a course called Create Your Own Country. Mostly working in pairs, students imagined and created their own countries, emphasizing one or more themes: maps political structure/government… Read More ›

  • June Academy: Egyptian Hieroglyphics

    By on

    For the first week of June Academy, I taught a 15-hour course on Egyptian Hieroglyphics. Many students produced spectacular results, as you can gather from this poster showing their name cards (explanation to follow): The student work is visually beautiful, much of… Read More ›

  • June Academy

    By on

    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

    By on

    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 ›

    Resuming my blog after a hiatus of too many months — eight, in fact! — so, stay tuned!

  • Dare Me and Exit, Pursued by a Bear

    By on

    “Exit, Pursued by a Bear.” Hmmm… where have I heard that before? It sounded like a Shakespearean stage direction, and it seemed familiar, but I couldn’t place it… so of course I looked it up. I’ll save you the trouble: it’s… Read More ›

  • Bullying Three Ways

    By on

    I originally started drafting this post well before last night’s presidential debate and the follow-up by Van Jones, but these events have slightly rearranged what I need to say. This thread actually started on September 27 with four talks (to different… Read More ›
