Dude.

Woodworking table with 6x10 pentomino tiling on a piece of copy paper. The 12 pentomino pieces drilled and cut from 3/4" soft pine surrounding print out. Hammer and straight edge in lower right.

Chonky pentominoes made from tracing paper printed tiling lines onto soft pine for cutting and marking internal corners for drilling. Bandsaw and saber saw to cut lines using 3/8" holes to make 90 degree turns. I feel like I know the subtleties of convexity in my body now.

Went through that recently. The app doesn't really work well either. GUI by Kafka

Does this maybe have to do with LLMs not having any sort of number sense? I guess by definition an algorithm that changes prompt words into probability compatible vectors really can't have any reasoning...I think I need another beer now.

What heaping pile of garbage.

I love discovering and developing characters who then find their way into the story.

This is like asking someone to do pullups for you to improve your tennis serve. It doesn't work that way.

Pentomino 5x12 has a modest 1010(I think that's right) tilings. Wonder how long that would take in this sort of online collaboration. I have like maybe four done...

Dinsdale!

I had a hard time putting it down.

Four paired images. Each pair consists of (1) a photograph of a pattern drawn in sand on a rotating disk, and (2) a graph showing a close approximation the sand pattern, rendered digitally on a grid of polar coordinates. From left to right, the patterns are (1) circle centered at the origin, (2) circle, off center from the origin, (3) linearly growing spiral, and (4) linearly growing spiral, but the path is more star-shaped and jaggedy than circular, and having seven "points" on the star.

"Hey Christopher!" they say. "Math On-A-Stick is great fun and all, but what does it have to do with school math?"

@davidbessis.bsky.social's book "Mathematica" proposes(I am paraphrasing) - the exercise of intuition and rigor as a primary path to mathematical intelligence. Math On-A-Stick activities engage people to investigate, create and collaborate on intuitive ideas.

Tonight is Krampusnacht my lovelies! (I'll be working on my yearly Krampus art of course!)

I am torn between bacon and tofu. Maybe both at the same time?

Yes!

And what I’m saying is this isn’t just the one kid.

All kids have fabulous ideas about mathematical structures. Let’s play with them!

Fabulous meet function.

This is amazing and might I suggest a short reading?

YouTube video by Jonathan Hall Using only 8's, can you create a sum of 1000?

A couple of weeks ago I attended a great session on problem solving with Ian Davies @axiommaths.bsky.social

I thought this was cool so I made a quick video.

I live in Minneapolis and know East African heritage folks who are Trump supporters. Most are also US citizens...the coming ICE action here is going to be crazy on so many levels.

I combine my discrete math research with my STEM+Art volunteer stuff to expand my "peer group" to include grade school kids. Seems to work pretty well. Helps keep me positive if nothing else.

Look Who You’ve Become You used to dream of couch-surfing across the world, untethered and unbothered, and now here you are, seriously considering an HOA townhouse. Reference #17806

Yep - that's me. In 2003 anyway. Now I'm on the board of directors...it could be worse.

I do volunteer work in the building where she has her office. Several of the kids I work with are East African heritage. Ugh.
Not particularly looking forward to getting tear gassed and arrested but "okidoki then."

I think a mini series is in order.

A promotional graphic for Her Maths Story featuring the documentary “Counted Out” by Vicki Abeles. The top section shows the HMS logo and a banner image with a crowd of people behind the film title “COUNT≠D OUT” in large red letters, alongside the tagline “Math is power.” Several film festival laurels appear along the bottom of the banner. Below, text reads: “Reflecting on ‘Counted Out’: A Conversation About Maths, Power, and Inclusion — By the Her Maths Story Team.”

In our latest blog post, we reflect on our #CountedOut screening event in mid-October and summarise the core action points we identified in the post-film discussion.

Share YOUR ideas on how you can take action personally to make the maths table more inclusive.

I liked the sequel also.

The main image shows unique snowflake designs created by combining 21st Century Pattern Blocks with Cuisenaire rods. The images are arranged in a 3 by 3 grid, with the top-left four squares merged to highlight a larger design.
