Eigenvalues of 2x2 matrix: another identity seen on twitter.

[Click here for a PDF version of this post] Here’s another interesting looking twitter math post, this time about 2×2 matrix eigenvalues: Theorem 1.1: Eigenvalues of a 2×2 matrix. Let \( m \) be the mean of the diagonal elements, and \( p \) be the determinant. The eigenvalues of the matrix are given by \begin{equation*} m \pm \sqrt{ m^2 – p }. \end{equation*} This is also not hard to…

For pretty much every crip person who isn't sure they count as disabled/divergent enough because well they aren't That disabled/divergent there's an asshole who is significantly less disabled/divergent than them and is convinced that they're the be all end all of that or all disability/divergency and all who are more are just an ableist stereotype / use their disability/divergence as an excuse.

Also yeah some people do go from the former to the latter. Don't know how often it is, but I had the fucking misfortune of helping my ex overcome the former for her then to go full latter on me. Definitely not saying the latter is *produced* by the former or whatever. There is no negative moral value in the former. Yes, you do count. Everyone else counts too.

Religiously i think about one of my twitter mutuals pointing out how aoki's design is subtly asymmetrical while ichiban is more symmetrical

when i think of it, masato's design is fairly symmetrical as well isnt it.....

Attention math and chess nerds: i have discovered a chess variant called cylinder chess! As the name implies, its chess but the board is a cylinder - the a file and the h file are next to each other. There is an website called cylinderchess.com if you want to mess around with it!

I really loved how I kept seeing people make warrior cats fanclans/comics/fics set in places they've lived/grew up, which got me thinking about what an Appalachian warrior cats would look like. I was just thinking about it as a fun exercise...and then I fell in love with the idea...and now I'm writing it.

Played fuckin D1 rugby players today (we are D3 for the record) and for the entire 30 minutes I was on the field they did not score. Neither did we, mind, but while I was with the pack those fucks did not score and that's what matters.

„ I’m so glad I managed to find you! My name is Leo and uh… I am here to return this. ”

The card is meticulously filled, returned the next day after it was out in the world.

„ Be honest. Would this make me spontaneous? Cause… I really wanted to fill this card. ”

So many boxes filled… yet somehow it is merely one bingo.

         He took the card from the stranger, surprised and impressed at how many he checked off. Plus, he was hot. What a great day. 

         “Man, I’m sure glad you were able to find me, too! Normally, that isn’t an issue with how I always wear neon colors, but now you know!” Luka smiled brightly. Yeah, the card said he wasn’t spontaneous, but the fact that the stranger had even given it to him said he could be sometimes. 

          “Giving me this does seem pretty spontaneous. Maybe, if you’re in the spontaneous mood today… You would want to catch a drink with me? Or maybe get to know each other somewhere a little more private?” He stepped closer to the other man, cocking his head slightly. “Because, you know, the middle of the street isn’t exactly the best place for these kinds of conversations.” He had no ulterior motives. Nope. Not one bit.
