I am on a mission to publish/post as much math as I can, aimed at a variety of mathematical levels and backgrounds. Here "math" is broadly construed: actual mathematics, meta mathematics, advice about academia, etc. To that end, let me write a thread here about the many ways I share math:

Are mathematicians "cooked", like the kids would say, because AI has found solutions to open problems in mathematics? I'm here to address the doom and gloom and tell you that Mathematicians are more relevant than ever! #math #ai

We are so excited this is happening! Ask me any questions, #TCSSky #MathSky!
Also, we are looking for a couple more project leaders, so if you want to know more about what that involves, please get in touch.

Let's learn how to row reduce matrices because it's a FUNDAMENTAL skill to do well in an intro to linear algebra class! On top of that, let's also figure out how to compute the null space of a 3x3 matrix #math #linearalgebra

When was Calculus invented? Or was it discovered? Who invented it? Or were there multiple discoveries throughout history? The answer is a lot more complicated than "Leibniz" or "Newton" #math #calculus

It was Newton's birthday recently... so let's *remove* Newton's name from the "Newton's method" which, in fact, should be called the Viete-Raphson-Simpson method instead! #math #newton #newtonsmethod

This is the @mathandcobb.bsky.social way and I admire him for it. I even made a TikTok account to follow him there. I wish I was even one tenth as good as he is at making videos (or even one tenth as good at writing posts as he is at making videos, honestly that would already be cool).
i have said this before but if you are actually interested in influencing people beyond a narrow circle of too-online journalists you will be making direct to camera videos on tiktok, instagram and youtube. if you primarily post on text-based social media then you're just dicking around.
