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).

Wordle, Wheel of Fortune, Jotto, & the Mathematics of Information Theory

Languages get simpler over the centuries, right?
After all, Spanish is simpler than Latin, isn’t it? And modern English is surely simpler than old English. So that proves it. Or does it? Well, no. There are at least two things that are wrong with the common claim… Read More ›

A gender-bending version of Stephen Sondheim’s Company

A strange book cover puzzle
You recognize this book, right? A glance at the cover makes it obvious what book this is. But then… You look again and start asking yourself why it says Garri, not Harry. And that reminds you of two things: It… Read More ›

Nice place to visit, but I wouldn’t want to work there.
There’s a fine line between a dystopia and a utopia. Unfortunately, Dave Eggers chose to draw his line with an extra-thick marker. I’m talking about his fifth novel (fifth or so—but who’s counting?), The Circle. The story focuses on the… Read More ›
