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).

Are we really living in the real world?
That question may now seem like a tired old trope. That’s because it all started with Philip K. Dick’s classic 1959 work, Time Out of Joint. For some reason I had never read this dystopian novel before, even though it… Read More ›

What are we? “Jewish Americans” or “American Jews”?
The excellent PBS documentary from 2008, The Jewish Americans, is an in-depth account of three hundred years of American Jews. I have no idea why it took me 14 years to watch it! The mix of presenters includes public figures,… Read More ›

Mangia, mangia al Tavolo!
Yesterday evening it was time for a return visit to Peabody Square, this time to Tavolo. It felt like my Italian grandmother kept urging “Mangia, mangia!” No, wait, I don’t have an Italian grandmother. OK, so my Jewish grandmother kept… Read More ›

Following 22 podcasts…
That’s too many, you say! Maybe so, but I really do follow 22 podcasts. First, though, I should say that I started following a 23rd podcast today. But another one that I followed up through yesterday is no longer producing… Read More ›

The golden age and more
Those who read enough science fiction, particularly those who read enough about science fiction, hear a lot about the so-called golden age. The golden age of what? Well, the golden age of science fiction, of course. When was that? Well,… Read More ›

Fortunately, things have changed in the past 30 years.
Or have they? A couple of days ago, as part of an ongoing trip down memory lane on Apple Music, I happened to be listening to a 1992 song by Fred Small, The Marine’s Lament. Since it’s only two minutes… Read More ›

New menu at Ashmont Grill!
The Ashmont Grill has a new menu! Admittedly the majority of the items on the menu are still the familiar old favorites, but plenty of new choices are available. It didn’t take much arm-twisting for Barbara and me to try… Read More ›

Learning Ukrainian: progress report #4
As you see from the title, this is the fourth of my weekly reports on my progress in learning Ukrainian through Duolingo. After today, I will switch to writing intermittent reports: i.e., whenever I have enough new to write about,… Read More ›

Just Thai
Delicious delivery from Just Thai Kitchen in Fields Corner last night: tom yum soup with extra shrimp; JTK wings; spring rolls; and stir-fried crispy pork-belly with Chinese broccoli in chili-garlic oyster sauce with white rice, more commonly known as Khao… Read More ›

Rod Stewart, Neil Young, Elton John, Bruce Springsteen, Frank Sinatra, Ringo Starr. What do they all have in common?
No, it’s not what you think. Yes, all of them are (or were) very successful and popular musical artists. But that’s not what I’m talking about. I’m referring to the fact that all of them are (or were) model railroad… Read More ›

Can you multiply 2573 by 389?
Pencil and paper only: can you multiply 2573 by 389? No calculators. And you have to get the right answer, of course. This is not a trick. “Of course I can,” you reply. “That’s a skill one never forgets!” Well,… Read More ›

More chaos! More CatNet!
The second novel in a series is always worse than the first. Of course that’s not true—unless you replace “always” with “often” or perhaps even “usually.” Or perhaps the wishy-washy “sometimes.” All generalizations are false, as they say. Including this… Read More ›

Learning Ukrainian: progress report #3
We have, as they say, good news and bad news. The good news is that my Ukrainian lessons are progressing well in their third week. The bad news—speaking as a teacher—is that pedagogically speaking the lessons are not designed nearly… Read More ›

Why teach gerrymandering? And why teach it in a math course in particular?
Gerrymandering is a hot topic in certain circles. Right now I am in the midst of writing and modifying some gerrymandering activities for my summer course at Crimson Summer Academy (CSA). Although we have taught various voting methods since the… Read More ›

The Complete Guide to Absolutely Everything* (*abridged)
Everyone needs to read this engaging, delightful, and informative book! Read it even if you’re not a math-and-science geek. Or maybe I should say especially if you’re not a math-and-science geek. Geneticist Adam Rutherford and mathematician Hannah Fry are well… Read More ›

Learning Ukrainian: progress report #2
It’s now one week since my first progress report. Apparently I’ve learned 95 new words in the past seven days. Duolingo previously said that I had learned 105 words in the first three days. Eek, am I slowing down? Aside… Read More ›

Are you smarter than a 7th grader?
Tip of the hat to Tanya Khovanova for sharing this problem: Is it possible to place seven points on a plane so that among any three of them, two will be at distance 1 from each other? This comes from… Read More ›

In praise of Omniglot
What, you may ask, is Omniglot? Well, the name gives it away (or hints at it, at least). Latin omni- ‘all, every’ followed by Greek glot- ‘tongue, language’ tells you that it has something to do with every language. And… Read More ›

More deliciosity from AG
Last night deserved another dinner at the Ashmont Grill—first time without masks in a couple of years! Barbara started with an “appetizer-sized” portion of three delicious barbecued pork belly sliders with mango BBQ glaze, shaved romaine, and pickled onions. Clearly… Read More ›
