I am entering my 21st year as a math teacher at Weston High School, the sole public high school in Weston, MA. It’s also my 44th year as a teacher altogether. In addition to my day job, I taught for 20 years at the Saturday Course in Milton, MA. I also teach at Harvard’s Crimson Summer Academy each summer; 2017 was our 14th consecutive summer.
Sometimes I work on educational software. I also read, cook, and continue building my model railroad whenever I can. For some reason I'm left with less so-called free time than would be ideal. Nevertheless, I manage to devote time to my wife, Barbara, and to our excessive number of cats as well.

A 5% discount (or is it a five percent discount? or a 5 percent discount? or a five % discount?)
Like many of you, I grew up learning the traditional rules about when to write out numbers in words and when to use numerals. Most professionals continue to use these rules today, as in the following awkward paragraph from Talking… Read More ›

Code Girls
You know how college recommendation forms often ask “What three words first come to mind about this applicant?” In the case of Code Girls: The Untold Story of the American Women Codebreakers of World War II, the three words would be fascinating, absorbing,… Read More ›

A Truck Full of Money
As you may know, Tracy Kidder is the author of some wonderful non-fiction books, including Soul of a New Machine, House, and Mountains Beyond Mountains. (He also attended both high school and college with me, but that’s not so important.) Apparently this really is a… Read More ›

Crypto: The KEY to Algebra.
This is a follow-up to yesterday’s post, where I wrote “I also gave a second talk, in a breakout session, on cryptography.” The crypto talk was a bit more informal than the keynote; it had an audience of about a… Read More ›

I gave the keynote address… and lived to tell the tale!
