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).

Off by two ems
There’s a flaw in the typography of the sign outside my dentist’s office. It’s neatly lined up in two columns, starting something like this [names changed to preserve anonymity]: John Smith, DMDMary Jones, DDSJoe Gummer, DDSRhonda Radical, DDS General DentistryDental… Read More ›

The Rottweiler
The Rottweiler is another excellent book in Ruth Rendell’s collection of thrillers (as distinguished from her Wexford detective novels). There is a richly developed cast of characters, including one who is the favorite suspect of the police but who the… Read More ›

Excellence without a Soul
I highly recommend Excellence without a Soul: How a Great University Forgot Education, by Harry Lewis. Though nominally about Harvard, it’s really about a much larger domain, including not only elite universities but also elite public high schools such as… Read More ›

Somersault
We tried to watch Somersault, acclaimed all over Australia. It looked like it might be of interest to film buffs and to anyone who works with teenagers (or anyone who has a teenager in the family). But neither Barbara nor… Read More ›

7+2=10
I just came across this clipping I had saved from the Boston Globe some years ago. Unfortunately, I don’t know the date, and it’s not really worth the trouble researching it. It quotes Joe Cazazza. who has finally retired from… Read More ›

A Madman Dreams of Turing Machines
Too often the books I review are mysteries (or novels in related genres, such as psychological thrillers). But not this time (and not next time either). Today we’re talking about a straight, mainstream novel — more or less. As you… Read More ›

Hey, Verizon, $.02 does not equal .02¢
You have to listen to this actual mind-boggling conversation between a Verizon Customer Service manager and a Verizon customer. Here is the first astonishing excerpt: Customer: Do you recognize that there’s a difference between point zero zero two dollars and… Read More ›

“Don’t think about thinking, it’s not on the test”
On NPR’s Morning Edition today there was a story about education and standardized testing, which included a debut performance of “Not on the Test” — a “gentle lullaby for students across the country” by Tom Chapin and John Forster. Do… Read More ›

New Year's Eve at the Ashmont Grill and High Fidelity
To celebrate the New Year, Barbara and I just had dinner at the Ashmont Grill, which offered a special menu for New Year’s Eve. Although we hadn’t really intended this to be a “going out in public” experience — like… Read More ›

Somebody Else's Music
I just finished reading Somebody Else’s Music, by Jane Haddam. One of the best in her Gregor Demarkian series, it is distinctly darker than its predecessors. Most interesting to a high-school teacher is its theme of high school as real… Read More ›

An obligation to vote?
Everyone knows about the 2004 decision of the Massachusetts supreme court legalizing gay marriage, and everyone knows that laws banning gay marriage have been passed in many states and are in the pipeline in others, but out-of-staters may not be… Read More ›

This year’s trip to Elmira was not nearly as interesting as last year’s.

Poincaré
On NPR’s All Things Considered tonight, there was actually a report about a math problem! To quote science correspondent David Kestenbaum’s report on the Poincaré Conjecture: The journal Science’s “breakthrough of the year” for 2006 is the solution of a… Read More ›

The Lincoln Lawyer
Recently I read The Lincoln Lawyer, by Michael Connelly, on the strength of an enthusiastic review in the Boston Globe last year. I was not disappointed. Maybe the Globe review explained the title, but if so I didn’t remember. Is… Read More ›

Windows Vista
I’m shocked, shocked, to see Microsoft labeled as “imitator, not innovator” in the review of Windows Vista in the New York Times of all places.

Balance or integration?
In many school districts, including Weston, we try to resolve the Math Wars by promoting a balance between skills and concepts. We tend to adopt the party line as promoted by former Education Secretary Richard Riley: We are suffering here… Read More ›

Black Maps
Black Maps, by Peter Spiegelman, is clearly not for just any random reader of mysteries. It combines the loner private eye — traditional in the noir side of the genre — with the much less hot-blooded (and tiny) sub-genre of… Read More ›

The Russo-Japanese War (of the condiments)
My colleague Boris gave me a jar of horseradish mayonnaise imported from Russia. Having enjoyed it on roast beef sandwiches, and even ham sandwiches, I decided to do a comparison with the Japanese equivalent, purchased at Kotobukiya in the Porter… Read More ›

Scheme overheard
This would be a pretty surprising remark to overhear at the next table at a random Chinese restaurant: I’m really enjoying programming in Scheme. At first I hated it, since it was so different, but now I really like it…. Read More ›

All the word geeks, game show geeks, and trivia geeks out there should go read Brainiac, by all-time Jeopardy champ Ken Jennings. Part autobiography, part history of game shows and trivia contests, this fast-reading book is fun to read and… Read More ›
