I ran over 150,000 simulated games of Pac-Man to find successful runs that took exactly one minute. Theyre not perfect, so technically this day clock takes 23 hours, 59 minutes, and 59.375 seconds.

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/

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.

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

@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.

Next part of the layout for the www.grannysquarecrochet.com project. Trying to keep things balanced with local strategies: put similar colors a knight’s move apart rather than same row/column, keep similar patterns away from each other, try to bring down bright colors using neighboring colors

After trying a lot of local rules for symmetry and other things, in the end I think the best strategy is to make sure things that are close together don’t have colors or patterns that are (1) too similar or (2) too different (?). Thoughts on arrangements? www.grannylifecrochet.com

Neat discovery: Two knots whose connected sum has an unknotting number less than the sum of the unknotting numbers of the knots. This provides a counterexample to an old conjecture.
