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).

The golden meanie
Fellow math nerds: check out Sandra Boynton’s pet, Fibonacci. Of course he’s a golden meanie: She describes him thus: The Golden Meanie is a mythical beast of pleasing proportions but unpleasant temperament. Oh well. You can’t have everything.

Vincent and Giraffe
Vincent likes his new giraffe rug. (Doesn’t look much like a giraffe to me, but what do I know?)

Is Chinese a language? (I.e., is Chinese a language?)
Note the subtle use of italics to express emphasis in the title. 😀 Why do people persist in referring to Mandarin, Cantonese, Shanghainese, and so forth as dialects rather than languages? Actually, there are a couple of good explanations — “good”… Read More ›

Weston alum blogs about Ireland and Tanzania.
Take a look at Studying abroad in Ireland and Tanzania, a wonderful travel blog by Weston alum Izzi Lambrecht, currently a rising senior at Holy Cross. For example, read her recent essay “Soooo How Much Agency Do We Have? Pondering in… Read More ›

Educated
I’m not quite sure how I feel about Tara Westover’s memoir, Educated. Comparisons with Hillbilly Elegy, which I did not like, are inevitable. The stories are actually quite different, as are the attitudes of the narrators. I had referred to J.D. Vance (author of… Read More ›

Tolkien, Adams, Rowling, Asimov: Re-reading a trilogy (or do I mean “series”?)
You’ll notice something strange in this screen shot: the Hitchhiker’s trilogy apparently consists of five books, not three. But of course that’s part of the shtick. What are we supposed to call it? The Hitchhiker’s pentalogy? Nah, the generic word is… Read More ›

Super Boys
“It’s a man, it’s a bird…” OK, stop right there. You know what this is about. But maybe you don’t. The beginning of this thorough biography of Jerry Siegel and Joe Shuster, creators of Superman, does indeed focus on their… Read More ›

Fireworks and You
“Hey, Larry!” shouts my neighbor as I take out the trash yesterday evening. “Where are your fireworks?” “People shouldn’t be setting off fireworks in residential neighborhoods,” I reply. “They scare cats and dogs.” “But you’re not scared,” he reasoned. “No,… Read More ›

Thinking (back) about Trig?
Why did somebody recommend to me a blog called A Portrait of a Math Teacher as an Aging Man? Are they trying to tell me something? I’m not sure that I should be thrilled about that 😀. Nevertheless, the recommended blog… Read More ›

Why do Asian-Americans excel at math?
Stereotypes, data, statistics, racism, tiger moms… what is this issue really about? Unless you want to be an ostrich and hide your head in the sand — hoping that the assumption behind this question is untrue — you really need… Read More ›

APs for all?
“Who am I to tell a student you can’t be in honors or AP?” said a guidance counselor at New Mission High School (a charter school in Boston) in a fascinating WGBH report. The gist of the report, titled “The… Read More ›

τ > π.
Happy Tau Day! Argh, I was supposed to post this yesterday, of course. If you don’t know what tau (τ) is, I could just tell you that it’s C/r, which is approximately 6.28, hence 6/28 is Tau Day. But that… Read More ›

Cinquecento etc.
For the second year in a row, Barbara and I went to Cinquecento for our anniversary dinner. The high standards of food and service remain (even with a clearly inexperienced server). But I should have checked the review I wrote… Read More ›

Adieu, Weston
Cliché Central calling: “Today is the first day of the rest of your life.” Yes, it’s a cliché, but it makes a point. Over the last couple of weeks, people kept asking me how I felt (not my favorite question,… Read More ›

Egyptian Hieroglyphics
Just completed the second week of Weston High School’s June Academy, in which I taught a course on Egyptian Hieroglyphics. In the photo below you can see two posters that showcase some of the students’ work, including carefully drawn name… Read More ›

Tolkien Exhibit
This certainly sounds like an exciting exhibit! Here’s a brief description: Tolkien: Maker of Middle-earth explores Tolkien’s amazing legacy from his genius as an artist, poet, linguist, and author to his academic career and private life. The exhibition takes you on… Read More ›

Isaac Asimov: The Foundations of Science Fiction
Oddly, I had never read James Gunn’s work of literary criticism, titled Isaac Asimov: The Foundations of Science Fiction, before this week. I say “oddly” because Asimov had absolutely been one of my favorite science fiction authors ever since I was,… Read More ›

Five languages in five days?
“Five languages in five days” is the name of the four-day course I have just finished teaching. Yes, you heard me: despite the name, it’s a four-day course. So which is it, five days or four? Let’s see what Lewis… Read More ›

Famous alums Josh and Anne
While clearing out my personal belongings from my office and my classroom (it’s amazing how much stuff one can accumulate in 21 years) I came across a copy of The Scarlet Letter that some miscreant had abandoned in our office. (That’s the… Read More ›
