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).

    As I mentioned in my post of two days ago, the sophomore component of the summer course I teach at Crimson Summer Academy focuses on models of voting. Although the emphasis is primarily on applied mathematics, the 2008 course was… Read More ›

    My regular readers know that I teach Quantitative Reasoning (QR) at the Crimson Summer Academy (CSA) over the summer. (If you don’t how what CSA is, read my blog posts from May 7, 2007, and April 30, 2008.) The theme… Read More ›

    Which is a better place to buy soft-shell crabs, the Legal Seafoods fish market at Chestnut Hill or the Roche Bros. supermarket in West Roxbury? The obvious answer is Legal, of course. Everyone knows that fish markets are better than… Read More ›

  • Peabody Square on Chronicle

    It was great to see my neighborhood featured on Channel 5’s Chronicle this evening! And no, it wasn’t because of crime, but because of diversity and the new transit-oriented development near Ashmont Station. The episode, called “Happenin’ Hoods,” included a… Read More ›

    No, this isn’t another one of those essays about the usefulness of technology in teaching math. This is a response to a fascinating post in Heather’s Comparative Childhood blog, in response to a newsletter from her daughter’s middle school. Here’s… Read More ›

  • Where can Dorchester kids get into college?

    Where can Dorchester kids get into college? Anywhere! Some of my Weston students believe that they are entitled to go to Harvard and BC and Bryn Mawr, but kids who go to public schools in Dorchester and Roxbury certainly aren’t… Read More ›

  • Money talks in Weston

    In Algebra II class today we happened to be talking about a certain prominent mathematician/physicist, and I remarked that he’s “the smartest living American, as he himself will be happy to tell you.” “That can’t be true!” objected one student…. Read More ›

  • Daddy’s Girl

    On the whole I recommend Daddy’s Girl, by Lisa Scottoline. Formally it’s a mystery, but it’s mostly about families. Like many mysteries, it also carries a theme of law vs. justice, and Scottoline does an effective job of exploring this… Read More ›

    Just finished reading J.A. Jance’s Justice Denied, the 18th novel in the author’s J.P. Beaumont series of Seattle-based police procedurals. Though it’s not one of her best, Jance clearly hasn’t gotten tired and can still write a taut mystery with… Read More ›
