Another PROMYS for Teachers workshop tonight. There were some really fun show-and-tell presentations:

* Shapes of various shadows of polyhedra.
* How to see every positive integer coprime to 10 has a multiple that consists of all 9s (or 1s?).
* The existence of “printer errors” like 2^5 9^2 =2,592.

I think my university might be the only one in the country that was open on Presidents’ Day and closed the day after Presidents’ Day.

Happy giving Tuesday! I’m fundraising for Cool Earth, a charity that supports rainforests and the people who live in them. As part of this, I’m taking a trip soon to spend a week traveling across Morocco on a monkey bike. 🤷🏻‍♂️

Check out this problem set, which connects Gaussian integers and Pythagorean Triples then considers adjoining a cube root of unity to Z and looking at analogous wonders:

Howdy! For most of the year, I live in the Pioneer Valley (western Massachusetts). It’s a lovely place!

My hobbies include running, playing disc golf, watching soccer, doing math, and teaching math. Lately I’ve become obsessed with the mathematics of chicken McNuggets. Who knew??
