Preparations are well underway for the Bridges #Mathart conference starting in Galway, Ireland, tomorrow. The #MathArt exhibition is being set up, and we'll have a set of wonderful talks and activities. As every year, I'll keep you posted! www.bridgesmathart.org/b2026/

Working on slides for my next talk...

AutoScarf update: the app works, the crochet pattern works, we are ready to roll once we get the website together! If you love 2-color reversible crochet and custom cellular automata algorithms, sign up to hear more and join the project at forms.gle/G8rWQVccZ4MM... #crochet #geek #math #awesome 🧶

Cover art for the May 2026 issue of the Notices of the American Mathematical Society. Here's a link to the issue: www.ams.org/notices

I converted a text message into a knight's tour. To decode it, follow the knight's tour, starting in the top left corner. The knight will traverse a succession of 11x11 tours, and each of these 11x11 tours corresponds to a letter. The message is a quote from Ursula K. Le Guin.

New project in the thinkin’ stage

The final artwork is coming together! One side is “night” and the other is “day”. grannylifecrochet.com 🌙☀️

Pulling up loops at the corners to attach the work to the backing fabric. Will weave in the long ends to stabilize the edges… www.grannylifecrochet.com #grannylife #mathart #geek #crochet 🧶

Geordi, Is there a way to enter our authorization codes by typing them instead of speaking aloud to the computer? Several crew members have complained that they need to memorize a new code after each use because coworkers overheard them. Worf

This is cellular automata applied to a staggered grid, like in beaded peyote stitch. All of these images were created with the same algorithm, what I call “Vines on a Fence.” The only difference among them is how I started each patch. I give the recipe for Vines on a Fence on page 105 of my new book

Hey #JMM2026 find me wandering around or at the Monday night Knitting Circle if you want to crochet a square based on a cellular automaton for a math/art/community exhibit www.grannylifecrochet.com

Granny Life update: About 160 squares here, sorting into a two-sided design. Expecting 50 more in the mail soon, need a few more. Deadline now Jan 8 to get a square to me if you want to join the project and have your work be part of an art exhibit in Paris! #math #crochet 🧶www.grannylifecrochet.com

Did I spend all day coding instead of doing the things on my long end-of-semester to-do list? Yes. Is my app cooler now? Also yes. mathgrrl.com/simultaneous...

Getting so many squares for the Granny Life project that the piece is now going to be two-sided. Had to make up a new whip stitch to get the attachment right. @crochet 🧶 Still time to claim squares and be part of the art at www.grannylifecrochet.com !

@mathgrrl.com I’m enjoying making squares for the Granny Life Project. Here’s a diagram that I made of what the basic stitch layout looks like if you want to make your own design, or if you want to color in what you’ve crocheted as you go along for your Granny Life square.

My friend showed me this daily web game: Which Year? It shows five photos, and you have to guess the year for each one. You can get four free digits with no penalty, but each digit can be used only once (in other words, you can get the thousands, hundreds, tens, or ones each only once). whichyr.com

At the TMiP conference in August, we announced the winner of this year's MEGA Grant - Christian Lawson-Perfect will be creating beautiful aperiodic tilings in the sand, as part of the #BeachSpectres project. Christian's write-up is here: aperiodical.com/2025... More info at http://tmip.uk/mega-...

Wonderful tilings all over the place at LaGuardia airport!
