Hallo, new Mastodon users! Here on mathstodon.xyz we've got a couple of mathematical emoji: :gauss: and :lovelace:. 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?

The three genders: Hunks, Babes, and Australian Wildlife.

You asked for it: github.com/halcy/Mastodon-LaTe Here's a mastodon LaTeX client! Screenshots of example output attached!

It's a balmy 17C here in the North East of England so we're all out in shorts and t-shirts 🌞 👙

In collection: Attention-grabbing titles
Due to the author's correspondence with Van der Waerden, Erdös, Baudet, members of the Schur Circle, and others, and due to voluminous archival materials uncovered by the author over 18 years of his work on the book, this book contains...

I <3 CW and mute. I want everyone to be able to speak. I want to choose what I listen to frequently. I want to explore. Here that's possible! No stress... I <3 even streams I mute, they just aren't for me.

I wonder if mathematical research breakthroughs can only become more complex and niche over time, or if there are still simple discoveries out there lurking in everybody's blind spots

wahey! Computer Modern Sans is back. Now every toot on mathstodon.xyz is mathematically rigorous.
Thanks to the thread involving @Gargron, @halcy and @codl for reminding me to sort it out

A from Matthew Doty, via John Baez:

Let a∘b = ⌊a/b⌋, for natural numbers a and b.
Show that (a∘b)∘c = a∘(b×c) for all a,b,c.

There's a proof using category theory! forum.azimuthproject.org/discu

LB is everything Masto hates, a birdsite RT and an image with no description, but it make me laugh hard.

Image is Theresa May saying "one of my constituents is moving to the Caribbean"

somebody (maybe Amber Rudd? I'm the worst at identifying people) saying "Jamaica?"

and May saying "yes."

It's a good job the department's having a bake sale today, because it's not even 11am and I've eaten both of my lunch sandwiches
