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).

    Check out the great photos at <legnangel.livejournal.com/564026.html>. I wish I could read the Russian text, but maybe Boris can help. Anyway, the question for me is why this collection resonates for me at several different levels. For one, the miniature… Read More ›

  • Bars, gates, & a ticket of admission
