Pinned toot

Hallo, new Mastodon users! Here on mathstodon.xyz we've got a couple of mathematical emoji: and . I'd love to add some more. If you can make a PNG image the same size as those, send it to me and I'll add it. Faces of famous mathematicians are an easy place to start; could we have some shapes, polyhedra, or other mathographics too?

Hello, I'm a postdoctoral researcher at Rikagaku Kenkyusho (RIKEN) (Wako Campus) in the iTHEMS program working in the field of mathematical #GeometryProcessing, data #visualization, and #mathart. I am a founding member of Math+ and a member of the Solid Modeling Association, Eurographics, SIAM as well as of the SIAM activity group on Geometric Design and the Solid Modeling Association. Furthermore, I am an associate editor of the Journal of Mathematics and the Arts. 🤗 #introductions

It's not very useful.

I've made a patch for just this feature at https://gist.github.com/christianp/629da435c959a6ed4853dce05dc155b4, though it's only really useful in conjunction with the rest of my mathstodon branch, which uses MathJax to render LaTeX in toot content: https://github.com/christianp/mastodon/tree/mathstodon-3.1.5
