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 Year of Living Biblically
I approached this book with some trepidation. The premise was intriguing: A.J. Jacobs, a moderately well-known writer for Esquire, would attempt to go for a year literally following all the rules in the Bible. I knew that Jacobs wasn’t a… Read More ›

Beauty Queens
Why do so many people have trouble with satire? I guess it’s because you have to approach it on two levels at once: the literal and the figurative. That can be difficult. So don’t read Libba Bray’s novel, Beauty Queens, if you… Read More ›

Why?
Several of my colleagues are wearing buttons that say “Why?” — and you may well wonder why. No, they’re not disaffected teachers who are questioning authority. Au contraire, they are the authority…and they want us to help each kid understand why s/he is doing what… Read More ›

Can math skills arise from a brain injury?
“A man became a math wiz after suffering brain injuries,” claimed the Washington Post. Hard to believe, isn’t it? We all know that brain injury can have a harmful effect on one’s mathematical abilities, but how could it possibility turn someone with… Read More ›

Explore mathematics
Sam Shah is always worth reading. (I think I’ve said that before. That’s OK. It’s still true.) Back on February 12 he published a post called “Explore Mathematics” — a good title, since isn’t that what we all want our… Read More ›

Plato at the Googleplex
Some people like to read bestsellers. In fact, lots of people must like to read bestsellers. Otherwise they wouldn’t be bestsellers — right? And then, at the other extreme, there are many people who don’t like to read at all…. Read More ›

The South Korean education system
South Korea has one of the best education systems in the world, right? After all, even President Obama thinks so. But not so fast. Read the “rest of the story” in an excerpt from Amanda Ripley’s book, The Smartest Kids… Read More ›

Worcester
“Worcester????” That was the reaction of almost everybody when they heard that Barbara and I were going to Worcester for a micro-vacation a few weeks ago. Not anyone’s idea of a vacation spot, after all. But we had a great… Read More ›

The importance of letting students stumble
One consequence of being away from blogging for over six months is that I’ve let some interesting posts from other bloggers just lie hanging without commenting on them. So, let’s look at two KQED essays on almost the same topic,… Read More ›

Back from the void
So…it’s been months and months, and I’ve totally gotten out of the habit of blogging. Time to resume! My new goal is five posts per week for the next n weeks (value of n to be discovered).

88 Wharf revisited
A little over a year ago, I wrote a post in which I speculated about whether 88 Wharf was going out of business. I had liked this Milton restaurant a lot back in 2009–2011, but by 2012 it had gone downhill…. Read More ›

“Off-track geometry”
JD2718 is always worth reading. I used to know his real name, but I’ve lost track of it. No matter; he teaches geometry, studies cryptography, and just turned 50, so we know he’s a good guy. A few months ago… Read More ›

Voynich
“A mysterious document that has bedeviled scholars and top cryptographers for more than a century,” says the Boston Globe. Is it written in code? Is it art? How old is it? Read the article for some tantalizing information — and lack of… Read More ›
