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 do you roll your eyes?
Don’t bother reading this post if you don’t know any teenagers — or if you never were one yourself. A recent column in the New York Times provides a perspective on understanding a common behavior of teenage girls (and boys…and tweens…). I… Read More ›

Who needs algebra? — A follow-up
Lucy Brownstein, a high-school student from Brooklyn, wrote a fine response to Andrew Hacker (see my post of February 7). You noticed that I didn’t say something like “a fine response for a high-schooler.” It’s a fine response, period. But still, it’s especially… Read More ›

Who needs an accountant?
So…why did Barbara and I see our accountant this afternoon, when all we had to do was routine income tax preparation? Several friends and students have asked me why I don’t just do my own tax prep? After all, I’m… Read More ›

“Stop humiliating teachers!” writes David Denby.
This commentary by David Denby in the New Yorker shouldn’t even be necessary. But of course it is. As everyone knows, the general public (especially, but by no means exclusively, Republicans) have a negative view of public-school teachers. So-called reformers want to… Read More ›

Misconceptions
You might have some prejudices about Iowa, and you might even have some prejudices about physics teachers, but please ignore them at this point. The ever-interesting Shawn Cornally has written a fascinating post with the title “These Misconceptions Are Keeping School… Read More ›

When will the two robots meet?
The other day I read an intriguing article in the New York Times about a simulation of two robots moving on model train tracks at the National Museum of Mathematics. Will they ever meet? And why are the robots beavers, when… Read More ›

Who needs advanced math?
I know, I know…you probably think I got the title of this post from Trophy Wives Don’t Need Advanced Physics, the famous book written by my colleague, Boris Korsunsky. But actually I got it from a column by Jane Karr… Read More ›

The Ruling Class
Wow! What a great film! How did I miss The Ruling Class during all these years — it was released in 1972! — that was 44 years ago!!! — but I am so glad that I have finally watched it. This over-the-too… Read More ›

17 equations that changed the world
I’m sure you’re wondering how there could possibly be 17 equations that changed the world — and what those equations might be. According to Ian Stewart by way of kottke.org, these are the 17: So what do we think of this… Read More ›

Talking Right
A clever title: “Talking Right.” It deliberately misleads you into thinking that it means “talking correctly,” perhaps with a subtle dig at those who use an adjective where an adverb is supposedly the right form. But that’s not what the… Read More ›

“It’s Time to Change the Way We Teach Math.”
That’s what Dan Meyer says in his new podcast. He’s right, of course. (He usually is.) His solution, as appealing as it is, can’t be the only solution. It can’t be all things for all people. Nevertheless, listen to his… Read More ›

Finding Your Roots
My previous post was about routes; this one is about roots. It’s not clear to me why it has taken me until Season 3 to start watching “Finding Your Roots,” a well-known series on PBS hosted by Skip Gates. This… Read More ›

Boston Globe delivery woes lead to a math activity: “Ruminating on Routes.”
If you’re reading this in the Boston area, you probably know about the Boston Globe’s problem with home deliveries this month. As soon as they switched delivery companies just before the beginning of the year, massive problems ensued — principally a complete… Read More ›

Yesterday was a professional development day in Weston. The entire K–12 faculty met together for a long lecture on special ed law, two workshops (I picked Google Classroom and 3-D Printing among a lot of choices), and a film about… Read More ›

Addicted to distraction?
From a recent New York Times opinion piece by Tony Schwartz: Addiction is the relentless pull to a substance or an activity that becomes so compulsive it ultimately interferes with everyday life. By that definition, nearly everyone I know is… Read More ›

Invisible City
Can you say “metaphor”? The title of Julia Dahl’s novel, Invisible City, may mislead you into thinking it’s science fiction, but it’s not. Not in the least. If you have to assign it to a genre, it’s a mystery — though it’s… Read More ›

Smiles of a Summer’s Night and A Midsummer Night’s Sex Comedy
Literary and musical connections can be rather complicated. First, we have Mozart’s well-known “Eine Kleine Nachtmusik,” often translated (literally but inaccurately) as “A Little Night Music.” Nachtmusik actually means “serenade,” but the literal translation has become even more well-known as a result… Read More ›

More Botswana charm from McCall Smith
It’s hard to believe, but apparently this is my seventh post about Alexander McCall Smith’s novels. Most recently (Dec. 15) I reviewed The Limpopo Academy of Private Detection. Since that point I’ve read two more in the Botswana series, one in… Read More ›

Teaching and learning are our priorities…aren’t they?
Surely our top priorities in a school must be teaching and learning…right? We know that a lot of things get in the way of those priorities, but still they’re the essence of what school is all about. At some point,… Read More ›

World Gone By
Almost exactly three years ago — on January 12, 2013 — I reviewed The Given Day and Live by Night, the first two novels in Dennis Lehane’s historical trilogy. At the time it wasn’t clear whether this would really be a… Read More ›
