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).

Heroes
As I was reading Paul Graham’s essay, “Some Heroes,” it struck me that I’ve never liked being asked who my heroes are. In his second and fourth paragraphs, Graham reflects on the question itself: I’m not claiming this is a… Read More ›

Two and a half years ago I wrote a brief negative review of Bringing Down the House: The Inside Story of Six M.I.T. Students Who Took Vegas for Millions, by Ben Mezrich. I suggested that the account seemed to be… Read More ›

Math is hard, let’s go shopping, says Barbie (and others)
Remember the big kerfuffle in 1992 when Mattel released a Teen Talk Barbie that said “Math is hard, let’s go shopping”? (Actually, if you look it up, you’ll find some references that quote it that way, and others that quote… Read More ›

The Big Nap
On February 26, I wrote a mildly positive review of Nursery Crimes, by Ayelet Waldman. Because another novel in this series, The Big Nap, appeared to be more interesting, I decided (without great enthusiasm) to give it a read. I… Read More ›

Career Day
Today was a very successful Career Day at Weston High School. I highly recommend the concept to other high schools — if you have a dedicated, highly organized team of people to take care of all the logistics. People who… Read More ›

Which is more important, sports or academics? And what about the arts?
Every school will tell you that academics are more important than sports. After all, it is a school. Even the most sports-minded principal will ban an athlete from playing football if his grades are too low, but no one would… Read More ›

Crazy Chinese words?
Don McLeroy, chairman of the Texas State Board of Education, certainly understands cultural sensitivity with his global perspective: “What good does it do to put a Chinese story in an English book?” he said. “You learn all these Chinese words,… Read More ›

How to create a blog
In one of those typical synchronicities, two of my students have just asked me how they can create their own blogs — a Weston sophomore yesterday, and a Saturday Course fifth-grader today. The Weston student suggested that I should post… Read More ›

What's the matter with math today?
What’s the matter with math education today? No, it’s not that kids don’t know the basics, despite what some people say. And it’s not that teachers are teaching “fuzzy math,” despite what some people say. Paul Lockhart has the correct… Read More ›

“You’ll enjoy the same success and happiness…”
Novelist Elinor Lipman wrote an excellent essay in the Boston Globe the day before yesterday, entitled “If I ruled the admissions universe.” I would like all high school juniors to read it. I just wish I could agree with it…. Read More ›

MCASitis
Today was the first day of disruptive MCAS testing. One of my sections of college-prep Algebra II was wiped out, the other was barely affected. There will be a repeat performance on Thursday. Somehow this is supposed to improve education,… Read More ›

Wellness Day
Today was Wellness Day at Weston High School — a day off for the students, and a day of professional development workshops for the teachers. “Professional development”: what thoughts does that phrase conjure up? FWIW, let’s see what Wikipedia has… Read More ›

Which comes first, the movie or the book?
In yesterday’s post, I recommended watching the movie of Mozart and the Whale before reading the book. And then I got to thinking about whether this was the natural order: after all, in most cases a movie is written after… Read More ›

Mozart and the Whale: The book
On February 20 I reviewed Mozart and the Whale: An Asperger’s Love Story. After seeing and enjoying this fascinating movie, I decided to read the autobiography on which it was based. (Can I still call it an autobiography when it… Read More ›

Goodbye, Arthur C. Clarke.
Another of the great ones is gone. Scientist, science fiction writer, and visionary Arthur C. Clarke died the day before yesterday at age 90. He is best known for the novel 2001: A Space Odyssey, on which the eternally rewatchable… Read More ›

Eye of the Beholder
I recently listened to the audiobook of Eye of the Beholder, by David Ellis. This work is a hybrid of two genres: the thriller and the police procedural. It’s definitely a page-turner — well, I can’t use that metaphor for… Read More ›

Don’t procrastinate! Goodbye, George, I hardly knew you.
Actually, I never knew you, sad to say. For 15 years now I have been intending to meet George Sanborn and talk with him about the MBTA (since my model railroad layout is based loosely on the MBTA of 1969)…. Read More ›
