## Nine More Kinds of Pi: Happy Pi Day 2015!

Since this blog takes its name from an artist who wrote about pie and painted π (see last year’s post), I try to offer a little tribute to this beloved irrational number each Pi Day. Today, at 9:26:53 am and pm (twice!), the date will spell out the first ten digits of the number. Well, it…

## Nine Kinds of Pie

Happy Pi Day! In recognition of 3.14 (today) and this blog’s Pi pie avatar (logo?), here are Nine Kinds of Pie (loosely defined). 1. The ratio of a circle’s circumference to its diameter: 3.1415926535. When I was a kid, I memorized the number out to its tenth decimal point. On a long strip of paper,…

## Free Pi!

I’d linked to it in my “Happy π Day from Crockett Johnson” post, and then it… disappeared. Blake explains why below: Vi Hart has a truly…

## Happy π Day from Crockett Johnson

This isn’t the only kind of “pie” that Crockett Johnson was interested in. In addition to “all nine kinds of pie that Harold likes best,” Johnson also drew inspiration from π (3.14159265…) — the ratio of a circle’s circumference to its diameter. In early 1968, he began the project of “squaring the circle,” constructing a square…

## Back-to-School Special, Part I: Children’s Literature & Asymptotes

In my decade of teaching Children’s Literature at the university level, I’ve learned a lot. But I never feel that I’ve learned quite enough to teach the grad class Critical Approaches to Children’s Literature. I’m grateful that I’m teaching it now and not ten years ago, but it’s one of those courses that makes me…
