To say nothing of series (television) and series (world)!

I would be delighted to participate in this book club!

I received my copy yesterday. It is BEAUTIFUL!

that moment in a project when you realize you're about to learn something

or been near a freeway, but not in a car?

I had a joke about Sophie Germain, but no one believed I wrote it.

I had a joke about Theseus, but I rewrote it too many times and it’s just not the same.

argh! Beginning of day foiled by Traffic Light of Death™.

Don't worry, no one died.

But it's only a matter of time.

Looking at you Snelling and Hoyt! 👀👀

Correction: I am told it was wodb

Big excitement in the house just now as an ad for “how did you count?” came across spouses Facebook feed for the first time. (In case you’re not keeping score, she is decidedly not on any of the mathier forums in any space, so this was a big deal)

On this note, in case anyone needs it, I am sharing again my little book “What I Noticed Along the Way” of 196 observations across one year: drive.google.com/file/d/1w0zL...

Pourquoi pas tous les deux?

Four paired images. Each pair consists of (1) a photograph of a pattern drawn in sand on a rotating disk, and (2) a graph showing a close approximation the sand pattern, rendered digitally on a grid of polar coordinates. From left to right, the patterns are (1) circle centered at the origin, (2) circle, off center from the origin, (3) linearly growing spiral, and (4) linearly growing spiral, but the path is more star-shaped and jaggedy than circular, and having seven "points" on the star.

"Hey Christopher!" they say. "Math On-A-Stick is great fun and all, but what does it have to do with school math?"

I NEVER want to hear anyone complain about participation medals ever again. 🤮

heck yeah! Congrats!

To be clear, I am still HIGHLY distractable. It's not like a whole new Triangleman over here.

After a topsy-turvy November (and May–October if we're being honest), I am back to writing this morning. It feels really good.
