Glad to know you made it. We appreciate the effort. There's not enough life reporting from #math -related hiking incidents here on Bluesky (yet).

Granny Life Community Build Project Granny Life

Math nerds and crafty geeks! You are invited to crochet a granny square based on a cellular automaton for the Granny Life project at www.grannylifecrochet.com.

Your work could end up in an art exhibit in Paris! There are plenty of motifs still available to claim :)

#mathsky #crochet 🧶

Love how the "just now" implies that we get a life feed from the hike. Has the family kept starting while the post was written, though?

I've signed up for @mathgrrl.com 's amazing #grannylifecrochet project at www.grannylifecrochet.com. I'm not a granny and I've never crocheted but this looks like a great opportunity to take part in mass participation maths algorithm based art. What's not to like?

Squares still available!🇫🇷🧶

I finally read this 2024 article by George Hart in the Notices of the AMS, "What Can We Say About 'Math/Art'?" www.ams.org/notices/2024...

He puts his finger on something that has made me uncomfortable or feel like an impostor when I say that I do mathematical art, when I know and am friends

Some of this week’s math-y art.

A hand-drawn diagram comparing two sets of numbers, one with a checkmark and one with an X, to visually explain the concept of coprime numbers.

A grid of ten by ten squares, with the top-left square labeled "1," filled with green checkmarks and red X's, resembling a sieve for finding prime numbers.

A hand-drawn diagram of the Pythagorean theorem, showing three squares of different sizes forming a right-angled triangle, and a separate equation showing the two smaller squares adding up to the largest one.

A hand-drawn diagram illustrating a division problem with a remainder, showing a large circle of dots being separated into three smaller groups and a leftover group.

🚨Paper Alert🚨
My PhD student Mrinal Dhume and I did a workshop at the Bridges #Mathart conference on "Exploring Math Illustrations: Draw, Deduce, Discuss!" Paper: archive.bridgesmathart.org/2025/bridges...
I'll do a version of the workshop at the upcoming @icerm.bsky.social #illustratingMath week.

One of my favorite podcasts chimes in on #illustratingMath in this episode, discussing the #geometry of honeycombs in the answer to the third listener question. Find the episode here: www.iheart.com/podcast/105-... and give it a listen!🎧

Jürgen Richter-Gebert was one of the keynote speakers at Bridges. He spoke about the iOrnament software he wrote for the iPad. I just downloaded it and made this design in 50 seconds. Wow!

I saw a bunch of people starting these squares at Bridges with yarn distributed on @mathgrrl.com‘s behalf, but I only just visited the pattern page. How cool! 🤯😍

To Laura’s tags, I’ll add #gameoflife #cellularautomata (which might not be active tags but should be) and #crochetsky. Also 🧶. 😉

Me wearing the look I submitted to the 2025 Math + Fashion show at Bridges Eindhoven. From top to bottom: a purple, blue, and teal polygonal quilted top I machine-sewed and hand embroidered, an aqua camisole, a two-thirds-circle skirt printed with a hyperbolic tiling outlined in purple that fades from teal to purple, aqua tights, white and silver platform shoes by United Nude. I’m also wearing a bead crochet bracelet in white, green, blue, and purple. My arms are spread wide to show off the bell sleeves of the top. Behind me is part of a mural by Carrie Patterson, Ash Scherer, and community art students from St. Mary’s College of Maryland. Spoonflower printed the fabric for the top and the skirt. The polygons for the top are printed on cotton jersey fabric, while the skirt panels and the fabric for the waist and pockets are on a cotton/linen blend.

Another submission photo for my look in the Bridges Eindhoven Math + Fashion show this July. I’m standing in front of a different section of the mural with my arms spread diagonally and a huge, open-mouthed grin. I think that Ariel Webster, the photographer, caught me in the middle of laughing at something. The top is stitched out of two-layer polygons that are like pillows without stuffing: purple dodecagons (12-sides), teal octagons (8-sided), and medium blue squares. There are also some cut-off slices of polygons to make the hemline and cuff-lines a little less unruly. I hand stitched these together to make a cropped top with flared sleeves, then hand embroidered the dual tiling in white running stitch. A decorative embroidered star appears in the center of each polygon, marking a vertex of the dual tiling. The tiles outlined in white are approximations of 30 45 90 hyperbolic triangles, the same triangles that appear in the Poincaré disk tiling in the skirt.

More post-Bridges posting: my Math + Fashion show outfit. The skirt and top feature two renditions of one triangle tiling in the hyperbolic plane. I coded the Poincaré disk tiling in Processing and @spoonflower-social.bsky.social printed it on fabric.

The wonderful Hannah Fry (@standupmaths.bsky.social had some beef with her over wrapping the earth in gift wrapping paper, I think) had an episode on aphantasia in her "Curious Cases" BBC podcast, if you want to check that out.

We have a brand new redeveloped website 🥳🥂🎊 New look and new features, but all the content is still there. Have a look plus.maths.org/content/

That's my kind of party. #MathSky

Looking forward to seeing it. What book will this be in?

make art! if it's the end of the world, you might as well make art! if it's not the end of the world, then the future will be better because people made art right now!

I had not seen that yet, will give it a look. Thank you for pointing it out 🙏

This reads like my first draft for answers of a multiple choice exam question. Fourth one is a note to future self, of course. #iTeachMath #AcademicSky

Jacquard looms

Punch cards

A piece being woven

An interesting piece of art.

Stop 2: The Textile Museum. Lecture, then browsing of the museum. Historical equipment, an active fabric studio, and artistic pieces on display.

The Evoluon

The Evoluon.

The windows were blocked off by walls, but we got a secret glimpse. The entrance was through a mirror in the women’s room!

The air filters in the eight meter basement.

Fantastic “excursions” at the Bridges Conference. Stop 1: The Evoluon. We had a discussion of the history and architecture of the building and a truly “behind the scenes” tour. (Details in the alt text.)

A modern university building, with "Tu/e" lit up on its roof, stands against a twilight sky, accompanied by trees and a colorful geometric sculpture on the campus grounds.

A woman stands on a stage, holding a microphone and speaking, in front of a screen displaying "Bridges Galway August 5-9 2026 Cead Mile Fáilte".

And that's a wrap for my report from this year's Bridges #MathArt conference. It was great, as always! Many thanks to the organizers for a wonderful week of #MathArt. If you're interested, join us in Galway, 5-8 August '26. www.bridgesmathart.org/b2026/ 👋
