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 are there so many Thai restaurants when there are so few Thai Americans?
According to the U.S. Census, far fewer than one tenth of one percent of Massachusetts residents identify as Thai. So why are there so many Thai restaurants? For instance, on Dorchester Avenue alone we have three: Just Thai, Thai Oishi,… Read More ›

A dozen new Miss Marple stories… but how is that possible?
Agatha Christie died in 1976. So how could she be publishing a collection of new Miss Marple stories in 2022? Did she leave them behind, only to be discovered four decades later and published posthumously? That’s certainly what a glance… Read More ›

Who cares about the burning of the library at Alexandria?

It’s Magpie Murders, not The Magpie Murders!
Yes, the definite article makes a difference…not because we’re being pedantic, but because we’re being attentive to anagrams and acrostics. Here’s the problem: I’m talking, of course, about the recent PBS Masterpiece series by Anthony Horowitz, titled Magpie Murders, as… Read More ›

Math anxiety

How can girls succeed at the highest level of high-school debate?
You know the problem, right? If a girl is meek and submissive, she won’t impress the debate judges. If she is strong and assertive, the judges will call her an aggressive bitch and she won’t do well. So there’s no… Read More ›

The plural of “you” is…“y’all”? “youse”? “yinz”? “you guys”? “you”?
Prescriptivists and right-wingers were all outraged back in Shakespeare’s day, when progressives and descriptivists started using the plural pronoun “you” to address a single person. It would be the death of the English language! How dare they try to change… Read More ›

What is your favorite mispelling?
