And the award for coolest math video ever goes to…Vi Hart, for her Doodling in Math Class series. These videos are “subversive,” as one of my colleagues (approvingly) labels them. The common theme appears to be that math classes in… Read More ›

Negative attitudes
Quotation from one of my students: “I hate it when people don’t like negative attitudes.” (Context: He had been solving a problem at the board and made a negative remark, causing one of his classmates to say that he was… Read More ›
Themes in precalculus
A course ought to tell a story. If it doesn’t, it’s just a collection of topics, not a course. Honors Precalculus at Weston definitely does tell a story. I was thinking about the themes of that story today, and I… Read More ›
Model railroad exhibit at the National Heritage Museum
Barbara and I just came back from a model railroad exhibit at the National Heritage Museum, sponsored by the HUB Division of the National Model Railroad Association. This was the same exhibit that I missed three years ago because of… Read More ›
Missing Justice
Although it was published over six years ago, I’ve just gotten around to reading Missing Justice, a worthy early contribution to Alafair Burke’s Samantha Kincaid series. Actually, I didn’t read it; I listened to the audiobook version, narrated by Betty Bobbitt…. Read More ›

Born to Kvetch
So what’s not to love about this book? Just don’t expect Leo Rosten’s The Joys of Yiddish, which is a much lighter and less consequential work. Michael Wex’s Born to Kvetch is a serious, in-depth, expert analysis of conversational Yiddish… Read More ›
Making order out of chaos
My principal has selected me to give the first presentation in a proposed series of talks to be delivered by faculty and staff; the audience will consist of colleagues, students, parents, and community members. I’ve written a very rough description… Read More ›
This Body of Death
This Body of Death, the latest in Elizabeth George’s series of literary mysteries, is well worth reading if you’re familiar with some (or preferably all) of the earlier novels in the series. I’m not at all sure, however, that it’s… Read More ›
