Science Art: Representations of the Braid Groups by Nancy Scherich, overall winner, Dance Your Ph.D. 2017.
“A representation is faithful if it has only one braid in its kernel.”
So, this is doctorate-level mathematics rendered as interpretative dance, and that is not a joke.
It’s really kind of beautiful. There’s even a plot, and a plot twist.
The other 2017 Dance Your Ph.D. winners this year are pretty great, too.

I appear to have killed my laptop. The very last thing I did on it, with a screen twice as bright as normal and no spacebar, backspace, or letters “g” or “x” – was finish a vocal track last night and load the song into this site. (Amazing what you can manage by cutting and pas…
Pottery charts are cool.
This expedition report is full of ’em.
Teeny tiny critters, hanging out in the water. They’ve got cilia in a circle, waving around their tops as if they were wheels, spinning.
