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

I hope I’m not rushin’ ya, but are you going to finish that danish? If not, I’ll polish it off.

Seriously. *One time* (definitely not today) I placed an order with Differential Geometry and got the shipping notification exactly 29 minutes later.

Delicate new earrings are in my shop, and would make excellent budget-conscious last-minute gifts for math-loving people in your life! Shipping within the contiguous US normally takes at most 5 business days. www.diffgeom.com/product/vola... More in alt text. #MathSky #MathArt #SciArt #Jewelry

Grades are in, so I've been playing in Desmos. Here's a dynamic transformation of a popular hexagon dissection into a rectangle. I've included parameters to control the shapes in the dissection. Can you make a square? www.desmos.com/calculator/y...

This, but for Rubik’s cubes.

Mwahahaha... Join me in about 30 minutes to see what the hell might do with 6 9-layer Rubik's cubes. www.gathering4gardner.org/news-2025-12...

There isn't a single problem "solved" by edtech that couldn't be fixed with smaller classes led by well-paid teachers given real academic freedom

This is the way.

When cartoon characters discuss numbers in base ten rather than base eight, it takes me completely out of my suspension of disbelief. Their society would not have developed that way.

Great puzzle. Kinda proud. I try to solve all categories in my head before guessing, but had to just take a leap today and guess for purple. Process of elimination for the blue, then home free. I was *really* tempted by some red herring categories, one of which had 6 or 7 possible tiles.

This is like Mr Rogers picking up Mjolnir

So real! Lol. Seriously, though, I had a conversation recently with a fellow geriatric millennial and we agreed that the $10 portable air compressor that plugs into your car's cigarette lighter is the most clutch investment anyone can make for their car trunk.

We'll be doing our final Finite Group Livestream of 2025 at noon uk time on 18th December - join me, @MScroggs.co.uk and @Ayliean.bsky.social for a festive feast of merry maths! Livestreams are for paid Finite Group members (from £4 a month, including some past recordings). Info at finitegroup.co.uk

It's totally a word for us in math! \end{rant}

Made this 2-sided this morning and realized that playing with the crossings generates two different mathematical links: One is L6n1 (which is apparently three fibers in the Hopf Fibration?) and the other is Borromean rings (L6a4). Urls for their katlas pages in the alt text.

At work I’m greeted by the @chalkdustmag.bsky.social with my article in, to learn I’m one of the items listed on the cover - above Taylor Swift (but below microbes)!

Sunday night seems the right time to post a gallery of (I hope!) every one of Catriona's geometry puzzles. notes.mathforge.org/notes/publis... Give it a moment to load ... there's a *lot* of them! #GeometryPuzzles #UKMathsChat #mathsky

❤️ Love this ❤️ @mathforge.org has done what I’ve never been organised enough to do myself, and catalogued every #geometrypuzzle I’ve ever posted on social media. It looks amazing!

I found this knot pattern this week and generated a planar embedding by first using stereographic projection onto the disk, tracing, and tweaking—all in PowerPoint and Photoshop. I really enjoy this process as it allows me to experience the structure of the knot throughout the very slow process. 😊

Okay... Now that I'm reading the paper more closely, I REALLY want to see which of these knots are Rubik's cube-able! 😂 Thanks @graveolens.bsky.social for tagging me!

Very cool! I was gifted a set of knot dice within the past few years and the tile set the authors use remind me of those.

This weekend would be a great time to submit your art for the exhibition to be held at the Joint Mathematics Meetings. Take advantage of this opportunity to share your work with over 5000 attendees this January in Washington, DC. You’ll need to submit by the 15th at gallery.bridgesmathart.org.

You shouldn't have to travel for hours to get maternity care, but Republican Medicaid cuts might mean you have to. It's shameful that a party that claims to be pro-family is cutting maternity care.

Nory Sontay Ramos was a thriving high school student in L.A. until she and her mom were deported by the Trump administration in July. For @msnbc.com, we visited her in Guatemala as she tries to graduate remotely while hiding from the same gang they fled years ago. www.msnbc.com/msnbc/news/n...

Teenage cuber, Andrey Maslov, was scheduled to speak at Bridges about making two-sided Rubik's Cube mosaics (the same image on both sides, with different colors). He found out at the last moment that he was unable to attend. So, he posted his talk on YouTube. www.youtube.com/watch?v=Uap0...

Getting excited for the Bridges fashion show tonight! On the runway will be the world premiere of my black and white rhodium plated knight's tour jewelry!

BIG day for mathematicians who play NYT Spelling Bee.

The same goes for surgery on many folds.

What is common knowledge in your field, but shocks outsiders? Definitions in math are not inevitable, but rather are choices people have made. We could make different choices if we thought it would be useful.

Remarkable. MSNC: "I want to reiterate this has been 100% peaceful." Seconds later, LA County sheriffs start firing on the crowd. Yet again, "law enforcement" deliberately escalated.

Here are all 54 distinct knots/links that Tanya and I have identified in our exploration of a specific class of knots on 9-layer Rubik's cubes. We have also determined that this list contains no redundancies & that any of the 4096 patterns that we began with is equivalent to one of these 54 knots.

I've been investigating a class of knots with Tatyana Khodorovskiy. We began with 4,096 initial patterns on a 9-layer cube and have reduced this set to identify 54 distinct knots in this class. You can read more about it in my Bridges paper from last year, but we're currently writing up the results!

The Free Speech Administration throwing down arguably the biggest sledgehammer against free thought and association in my lifetime.

This explains it! Thanks for including me, Martin.

Apparently, “notationally” is not one of the six pangrams today.

#MSH45 | 8:32 a.m. The ground shudders. A M5.1 quake hits beneath Mount St. Helens. The bulge collapses outward. Within seconds, a lateral blast surges through the disintegrating slope. 7 miles north, Gerry Martin describes what he sees—until the radio goes silent.

Younger folks around here might shocked to learn that once upon a time Bill Clinton let a few campaign donors have a sleepover at the White House & the national media spent months treating it as the greatest scandal in the history of the republic

Thinking about @steckl.es and my Mathematical Objects podcast. Last season we chatted poetry, category theory, space-filling curves, parallelepipeds, voting & road sign regulations, we stared deep into an area the size of Wales and feasted on a universe of cake. Search wherever you get podcasts.

this is a letter to the editor from a high school track runner who came in second to a trans girl in a race. her state house rep in maine started talking about it. so she wrote this: www.pressherald.com/2025/05/14/r...
