ok i get it now, most people need plans and structures so then they can study what they're really into in the future

btw today i'm doing operations on topo spaces, i love that already

i gotta say i don't buy all them planning strategies and tips that require more effort than just sitting and doing the work

i mean that might help some people but i find that when i am doing something important to me i need no plans nor do i need motivation, i also don't procrastinate, everything falls into its right place

and if achieving something takes so much effort in preparation, is this even supposed to be a thing? idk, maybe that's the reason why i have no external proof of my work lol

Theory Time

The reason endermen don’t like it when you look at them is because they communicate telepathically with one another by locking eyes! Humans are absolutely not designed to do this so when we look at them we are accidentally projecting all of our thoughts into them at the same time and it hurts :(

gonna list my general goals, not necessarily what theorems i want to learn but rather some global "fix your life" things. gonna post about it every week to keep myself accountable

(1) wake up at 9 instead of 12. go to sleep at 1 instead of 4. if my current circadian rythm is here to stay, it's gonna be a fucking nightmare in november. first goal is to start going to sleep between 2 and 3

(2) concentrate on lectures. my focus is really bad when it comes to listening to someone. i have some interesting lectures downloaded and want to use them as training. first goal is to be able to actively listen to one for 30 minutes, then I can have a break for a zone-out

(3) get used to not checking my phone every damn 20 minutes. first goal is to have two 1-hour intervals daily of not checking it

probably will add some more soon

I found the most beautiful math book I have ever seen

it covers the basics of algebraic topology: homotopy, homology, spectral sequences and some other stuff

one of the authors (Fomenko) was a student when this book was being published, he made all the drawings. imagine being an artist and a mathematician aaand making math art

just look at them

other than those drawing masterpieces there are illustrations of mathematical concepts

I'm studying homology right now, so it brings me joy to know that this book exists. I don't know how well it's written yet, but from skimming the first few pages it seems fine

I just finished watching a lecture about exact sequences and I find the concept of homology really pretty: it's like measuring to what extent the sequence of abelian groups fails to be exact

I'm trying to find my way of taking notes. time and again I catch myself zoning out and passively writing down the definitions, so right now I avoid taking notes until it's with a goal of using the writing as a tool for acquiring understanding. I'm trying to create the representations of objects and their basic relations in my mind at first, then maybe use the process of note-taking to further analyze less obvious properties and solving some problems

I will post more about it in the future, we'll see how that goes

Very funny when mathematicians call weird edge cases "pathological".

Mathematician looking at a function that's continuous everywhere but differentiable nowhere: yeah that function has something wrong with it.

Thinking about how when my oldest brother took Japanese classes his professor was like your pronunciation is really good 😊 but you need to watch movies that aren't about the Yakuza because you sound like a criminal

Right. So. A Tarot sequence of three cards, A -> B -> C is exact if everything you take from A as part of B is all that you leave behind when you interpret B as part of C.

For example let's look at a relationship spread:

Self -> Other -> Dynamic

Start with the Self, then identify the self with aspects of the Other; those aspects are precisely the parts of the Other that you ignore when interpreting the Other in the Dynamic. With me so far?

Let's add another link to the sequence:

Self -> Other -> Dynamic -> void

"void" has no card. It has no interpretation, consumes all, and yields nothing. All aspects of the Dynamic are consumed by the void, but when we know this sequence to be exact this tells us much:

The aspects of the Self that we see in the Other are those parts we leave behind when we see the Other in the Dynamic. The aspects of the Other that we see in the Dynamic are those parts we leave behind in the void (which is everything). So for this sequence to be exact we know that the Dynamic is fully explored by those parts of the Other than we cannot identify with the Self.

"based and purple pilled" with deleted vowels. the first adhd medication I tried was life changing, I could finally study and function (half-)properly, and the pills are purple, hence my version of "based and red pilled", which I probably don't have to explain

Guys please reply to this with what your url means or references I’m really curious

lmao wtf people seriously say shit like "math is homophobic"? because queer people can't do math… a priori?? isn't it inherently homophobic to claim that homosexuality implies being bad at math? this is the most unhinged thing I've seen this week

It's so funny to me when people reblog math posts on this site and say shit like "this is homophobic" "this is an attack on queer people" like hello this is tumblr. OP is queer. Like we've got a HANDFUL of cishets here on mathblr but most of us are queer. Because it's tumblr. And everyone is queer on tumblr. If you see math on this site, a queer person probably put it there. Stfu about "gays can't do math" if it's on tumblr, gays can do it, that's why it's on tumblr.

And of course there is also a large and brilliant and beloved queer math community off of tumblr but I just think it's extra funny when people don't notice it ON TUMBLR.

Alan Turing didn't kick the Nazis' collective ass laying foundations for the field of computing and then go on to also lay foundations for the field of biomathematics, Leonardo Da Vinci didn't give us fundamental physical and mathematical diagrams used in engineering well beyond his time, Moon Duchin doesn't study the math of fair redistricting, Chad Topaz and Jude Higdon don't analyze criminal sentencing disparities, et cetera et cetera, for y'all to call math homophobic and an attack on the queer community.

It's always funny when a math book or a paper starts out with like a foreword/introduction type thing but it calls itself an "Apologia"

Like "Sorry i wrote a new book, this is why i thought i had to do it. Please forgive me."
