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).

What's the matter with kids today?

No driver's license? Something must be wrong!
In a tone of shock and amazement, one of my sophomores asked me, “Did you hear that our new principal doesn’t have a driver’s license?” Several of his classmates chipped in, in a similar tone. Apparently this was supposed to… Read More ›

Miniature worlds
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
Almost 25 years ago, my friend and colleague Phil Lewis wrote an article for Kaleidoscopes called (if memory serves) “Subject to Gates and Bars.” If I were better organized, I would be able to find that article; Phil always describes… Read More ›

Finally TiVo
So we finally gave in and got a TiVo box. I think it was a recommendation by Ira Glass that did the track. Most of the setup was painless, but it’s been very frustrating trying to connect it to our… Read More ›

The soul-stealing iPod and fuzzy math
Does the iPod steal music’s soul? Do these numbers make sense? Here are the views of Tony Brummel, founder of Victory Records: iTunes “makes music disposable. It makes it a faceless impulse item. It steals its soul,” according to Macworld… Read More ›
