a million years later, this is still the neatest thing I've ever made, with huge help to the person at TMC13 (!) who figured out how to make the planets orbit www.desmos.com/calculator/d...

I just took a train on Friday and was in the quiet car and it was heaven! My trip was only 2.5 hours though.

Loved this HS student's #fractal, so #geogebra'd it up mathhombre.tumblr.com/post/7970450... #mathart

Very nice! The calculations will get a little funky since the rule is a little different for those squares that have larger squares on bothe sides.

Year 10 found expressions for shaded areas.
Made this last year for an extension but it was nice spending a bit longer on it.

Here is a @desmos.com activity about the symmetry-preserving transformations of a square, inspired by my colleague Tom Jameson.

For a really great intro to how this relates to group theory, see this by @stevenstrogatz.com archive.nytimes.com/opinionator....

Never saw a graphical description of the difference of squares factorization so I made one. I don't know why.

Ooooh I’d LOVE this! Could I reach out in a while? I’m in start of year stress mode but I’m hoping soon things will feel routine?

You did! I have to plan a class for 18 students for 7 days for 6 hours a day. It feels exciting… and daunting.

On Friday at Noon (EDT) I am giving a talk in the New York Combinatorics Seminar. The title is: "Mathematical illustration through a combinatorial lens" in which I share my decade-long journey as a mathematical artist and jewelry maker and how it intertwines with my combinatorics research.

Finished a cape thingie that I started knitting in August.

I learned a few more basic knitting skills (mainly making short rows/turning) but it’s still very beginner even though it looks fancy!

It’s a free pattern on ravelry: www.ravelry.com/patterns/lib...
