This Proof Is Left As An Exercise For The Grader

Are all people who do functional analysis allergic to using im(T) and ker(T) to denote the image and the kernel of an operator T or is it just my lecturer?

So, my spouse has been exploring his gender lately; he also just built himself a new laptop. Today he told me that he in an attempt to process some genderfeels through metaphor, he made a post on a trans forum along the lines of: "I'm a lifelong Windows user and I think I'm pretty good at it. I want to find out what Linux has to offer but I'm afraid I wouldn't be any good at it. And how do you choose the right Linux distro, anyway? Do you have to try them all?"

The responses, he said, were a mix of useful advice about feeling out your gender and useful advice about choosing a Linux distro.

I love trans people so much

REBLOG THIS POST IF YOU ARE A MATH ENJOYER

No it is not optional, I desperately need to follow y’all so that there is more math on my dashboard.

I'm a huge hypocrite, if we're being honest. If I haven't had a beverage and it's been dark for too long I'll be like "nothing has ever been good and I shall die ;__;" but as soon as I get a little sip of water and it's sunny outside I'm like nvm I'm thriving I love life :)

But if my houseplants do that exact same thing, I'll call evert single one of them an overdramatic bitch.

Actually this isn't how we count.

These are hand symbols (Hasta or Mudra) used in various different Indian dance forms. They have different names.

👍 is shikaram. ✌️ Is actually slightly different, the middle finger comes forward and the index goes backwards almost like you are trying to twist them. It is called Kartharimukam(scissors).

say what you will about the reserve bank of india these are some cracking coins

What, the forest-dwelling entities with imperfect human mimicry who insinuate themselves into groups of hikers? Yeah, we had one of those. Clocked it immediately, of course. Honestly it kind of fell in that so-inept-it's-kind-of-charming range. We just played along until it'd had it's fill of marshmallows and shambled back into the treeline. We might have been violating some kind of killjoy wildlife contact best practices but what the hell, can't plan around every little thing. Why, what happened to you guys

I just watched a beutifull and and emotionall video by Patricia Taxxon on youtube and it reminded me of something I used to be very close to but have since stopped doing, and that is to just look at math and play! Math is inherently arbitrary! By definition math is art! It's a way to grasp at the world, yes, but it's also a vehicle into creating entierly new worlds! New dimentions! New, novel kinds of logic and causality! You can take any single operation, map it to an arbitrary unused symbol, and just! Use it! In different eqasions! In different contexts! You can stretch you conceptions of what is a number, a value, space itself, and it's all so fun and inventive, and you can draw fractals! So so so so many fractals!

And it can be hard to see it that way. Especially after going through public education, especially after being beaten into the ground with incomprehensible notation of lond dead professors, after being offered only the most optimised and abstracted of formulas with no basis on which to place them but! Math is a jurney! To discovery of not only reality but yourself! What compells you; what you see with ease and what just does not compute, what is the rjeason for all of that notation, what would happen if you just assumed something stupid! And that stupid thing can sometimes be revolutionary to your understanding of numbers! Math and notation is an art form and I'm heartbroken people aren't seeing it for that! Because it's too esoteric or intimidating or because they've been made to feel like they could never succseed at it! Becouse someone hurt you in an attempt to teach you how to fill out a standardised test.

My plea is, to give math a try, look for something that resonated with you, or just draw some triangles and sqares; make a fractal; define how it's built and try to see what comes of it, there's so many things to discover. Try to proove a simple formula. Visualise! Solve a simple problem! It's intimidating; but it doesn't have to be! It's impossible to fail at mathematics, you can only learn from your mistakes, I beg of you, try.

two words that really shouldn't be the same word:

inductive in "inductive reasoning" (philosophy term)

inductive in "inductive proof" (math term)

I have a headache
