Seems like a good time to advertise mathstodon.xyz, a Mastodon instance run by some math(s) people I know, based in the UK.

I'm going to stop posting explanations of math and physics on Twitter. I may still talk to folks I know here, and announce stuff like conferences and lectures.
To see my math and physics posts, check out Mastodon:

Our design for the Impact Award was inspired by our work on vascular networks for 3D-printed organs. Intricate branching fluidic networks printed inside a clear block reveal the Formlabs logo when injected with contrasting resin n-e-r-v-o-u-s.com/blog/?p=9274

I originally took this photo illustrating stereographic projection in 2014. Soon after, someone attached a click-bait caption to the image, and it has been bouncing around the internet ever since. Here, I explain what the image is really about.

When I close my eyes, all I see are strings.
I've become somewhat obsessed with the patterns made from stretching straight lines across a circle, better known as string art. Simple rules can yield beautiful patterns and reveal hidden math.
Join me on my explorations:

I gave a talk at last month. Moriah Aberle was in the audience and told their roommate Nicky Sherrick about our Skew Dice. Nicky then made this big ceramic version! I'm told that it's not very roll-able, but it looks great!

So the story is that they want to promote my book, but they don't even know my email address? Very weird. 3/3

The weird thing is that the number they appeared to call from was a local area code number. Which doesn't make sense for some international promotion company. I told them to email me if they had some serious proposal, to which they asked for my email address... 2/n

I got a new (to me) spam/scam phone call last night. Someone called, claiming to represent a company that wanted to promote my book overseas. They knew my name, and the title and publication date of the book - not surprising since that's all public knowledge. 1/n

When drawing train track diagrams in geometric topology, it's important to get the signals right so your trains don't crash into each other.

Art Prize! Check out our son's entry made entirely out of binder clips! This massive sculpture is made out of tens of thousands of binder clips linked together to form a single surface throughout. This effect is achieved through the use of negative Gaussian curvature.#mathart

This hits a really fun nexus of imaging/photography and math. Check the yt link to see the math behind the illusion. Very clever. And very illustrative of how perspective changes perception.

If you arrange a collection of spheres in various symmetrical patterns on a hypersphere, finding the ways they can turn while making rolling contact with their neighbours leads to all kinds of fun linear algebra and group representation theory.
