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).

  • Quotation from a math student

    Quotation from a math student at a college that will be unidentified to protect the innocent: That exam was unfair. You made us understand the material. I’ll memorize the phone book if you ask me to, but you can’t expect… Read More ›

  • Weston supports its schools

    On Saturday the residents of Weston voted to override the restrictions of Proposition 2½, thereby providing another year of adequate funding for its schools. Yes, I know that “they can afford it,” but in all too many well-to-do towns the… Read More ›

  • Black Orpheus

    Just watched Black Orpheus on DVD. I hadn’t seen it for at least 35 years, but it still holds up as a classic masterpiece, especially the cinematography. Highly recommended.

  • Rating high schools

    What kind of metric should we use in order to rate high schools (assuming, of course, that we should rate high schools comparatively, which is a big assumption). According to Newsweek, we should be calculating A/S, where A is the… Read More ›

  • The No. 1 Ladies Detective Agency

    By on

    I often find that I’m in the midst of reading two books at once, especially if one is fiction and one is non-fiction. That’s what happened to me recently, finishing both Freakonomics, by Steven D. Levitt and Stephen J. Dubner,… Read More ›

  • Freakonomics

    By on

    Just finished reading Freakonomics, the much-discussed popularization of applied statistics by Steven D. Levitt and Stephen J. Dubner, economist and writer respectively. Although Levitt won the Nobel Prize for Economics, this best-seller really is about “applied statistics” rather than economics…. Read More ›

  • The importance of blogging

    “Blogging is good for your career,” said reporter Penelope Trunk in a Boston Globe article on April 16. This is a bit surprising, given all the stories about people who have been fired or not hired because of what they… Read More ›

  • Separated by a common language

    First I was told that Churchill said it. Then I was told that it was Wilde. But actually it was Shaw who described England and America as “two countries separated by a common language.” Language is part of culture, so… Read More ›

  • London

    We’re staying at 22 York Street, a lovely B&B just off Baker Street in London. Of course it’s foolish to try to make a dent in the to-do list when one has only a short stay in London, but we… Read More ›
