You may have seen a picture of movie film. A movie film consists of a large sequence of still images, which are presented so rapidly that the viewer perceives it as motion. This is true whether the pictures are photographic images of something with physical existence, or whether they are drawn or composed artwork. (Collecting… Continue reading Continuous? Step-wise? What’s up with that?
I’m one of those aging folks who still remember the original run of Star Trek (no colon, no The Original Series or any other kind of elaboration — just Star Trek). It was a groundbreaking show, and whether you like it or not (there are plenty of reasons to do both), it held out a… Continue reading Mr. Spock, Pseudo-scientist
I rather like Arthur Conan Doyle’s Sherlock Holmes stories. I should also admit that I’m not a hard-core devotee of mysteries in general. If I were, I probably would find the frequent plot holes in the Holmes corpus more annoying than I do. I enjoy them mostly for the period atmosphere, the prickly character of… Continue reading The Sherlock Holmes Law
I’m not a mathematician by training, but the language and (for want of a better term) the sport of geometry has always had a special appeal for me. I wasn’t a whiz at algebra in high school, but I aced geometry. As a homeschooling parent, I had a wonderful time teaching geometry to our three… Continue reading Reflections on Trisecting the Angle

The economy seems to be the symptom that garners the most attention, and there are people across the political spectrum who want to fix it directly; but most seem to agree that education is at least an important piece of the solution. We… Continue reading STEMs and Roots
One of the college majors most widely pursued these days is computer science. This is largely because it’s generally seen as a ticket into a difficult and parsimonious job market. Specific computer skills are demonstrably marketable: one need merely review the help wanted section of almost any newspaper to see just how particular those demands… Continue reading Computer Programming as a Liberal Art
When we first started homeschooling our kids, Christe and I generally divided our tasks according to our general areas of relative expertise — she took the more scientific and mathematical subjects, while I dealt with the more humanities-oriented ones, especially those having to do with language. But it didn’t always fall out that way, and… Continue reading Learning and teaching…and learning
My intermediate and advanced Greek and Latin classes are largely translation-based. There’s a lot of discussion among Latin teachers about whether that’s a good approach, but much of the dispute is, I think, mired in terminological ambiguity, and at least some of the objections to translation classes don’t entirely apply to what we’re doing. What… Continue reading Making Sense and Finding Meaning
