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).

  • This year we decided to cut back on the number of topics

    By on

    Less is definitely more. In the first summer of the Crimson Summer Academy (2004) we attempted to explore two different (but related) topics in our Quantitative Reasoning (QR) course for rising sophomores: Visual Representations of Data and Models of Voting…. Read More ›

  • Ruth Rendell: Thirteen Steps Down

    By on

    “The doyenne of the crime writing world” is Mystery Ink’s description of Ruth Rendell. I’ve long been a fan of her fiction, not only her traditional detective series featuring Inspector Wexford but also her psychological crime novels. By this point… Read More ›

    This was the last day of this year’s session of the Crimson Summer Academy, which has been the subject of various posts earlier in this blog. As always, it was an excellent session. As always, there were some glitches. But… Read More ›

  • More From Polymath

    By on

    In yesterday’s post, I recommended an article in the Polymathematics blog. That entire blog is well worth reading. For example, consider a discussion of whether 0^0 should be 0 (because zero to any power is 1) or 1 (because anything… Read More ›

  • Why .999… really does equal 1

    Do read the fascinating (but long) post in Polymathematics about why .999… really does equal 1.

  • Cell phones: good or bad?

    By on

    It sounds like a silly question: “Are cell phones good or bad?” Clearly they’re good in emergencies, but bad when they ring in the classroom. Clearly they’re good when you’re on a bus and have to call to say you’ll… Read More ›

  • World's best version of Life

    Check out the world’s best version of Conway’s Game of Life.

  • S is for Silence

    By on

    Let’s see. This must be the 19th book in Sue Grafton’s alphabet series. So it must be also be the 19th that I’ve read, since of course I’ve read them all in order — mostly because they’ve been published that… Read More ›

  • McCall Smith in Germany

    In several previous posts, I have written about the first five novels in Alexander McCall Smith’s Botswana series, featuring Precious Ramotswe, as well as the first novel in his Edinburgh series, featuring Isabel Dalhousie. Now I’ve read all three in… Read More ›

  • McCall Smith in Botswana

    In a much earlier post, I discussed Alexander McCall Smith’s No. 1 Ladies’ Detective Agency, the first in a series of mystery novels taking place in Botswana. In the intervening months I have subsequently read the next four in the… Read More ›

    By on

    I have recently read Jasper Fforde’s first three Thursday Next novels: The Eyre Affair (2002), Lost in a Good Book (2003), and The Well of Lost Plots (Feb. 2004). Where do I begin in describing this offbeat series? One reader… Read More ›

  • Mathematical Gangsta Rap

    By on

    Filled with in-jokes about cryptology and computational complexity, Mathematical Gangsta Rap is an amusing combination of high culture and low culture. But you’ll have to make your own decision about which is which.

  • Suddenly a new car

    By on

    Our trusty Ford Escort station wagon, which was relatively cheap but reliable, finally stopped being either and just died. When you have a nine-year-old car and you’re faced with a $1000 estimate for repairs, you have to decide whether it’s… Read More ›

  • End of hiatus!

    Finally back from a blog hiatus of almost three months! I am very much looking forward to the new vesion of Blogger, which will permit labels on posts to denote categories. This feature will help viewers who are interested in… Read More ›

  • Quotation from a math student

    By on

    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 ›

    Dorchester finally has a good Chinese restaurant! For years we’ve had to cross the border into Quincy to eat at the best Chinese restaurant around, the Great Chow (which, as I only discovered two years ago, is owned by the… 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 ›

    So I’m teaching a course called “Create Your Own Computer Game” to fourth-graders at The Saturday Course, and last week I’m talking to Eileen, an artist who teaches “The Art of Drawing”; I happen to remark that some of 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.
