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

no fuckin way

mood: filling an open set with dyadic cubes and pretending this is studying measure theory

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

Mathematicians be like:

Def 1.1: A function f is fucked-up iff it is not Lebesgue measurable

Def 1.2: A function is evil iff its graph has non-integer Hausdorff dimension.

Exercise 1: Prove that there exist fucked-up and evil functions

I'm glad I never encoutered anyone with such serious mindset while I was studying programming because now I wouldn't have as much fun writing branchless things in python, which is completely useless in highlevel languages but I just can't resist

I feel like some people are too serious with learning how to program. “I gotta be the best in this and that and build this and that to impress this employer” blah blah, that kills the fun out of programming. I see a lot of people (bashing people on Twitter again and actually a few people on here too, oops) making programming such a serious topic and you can’t have fun in it. Besides the proper syntax, documentation, best practises whatever, people in the tech community have putting up “rules” about how you should program and what to learn and if you fall out of that, you get ridiculed for it. Literally making it less fun.

Someone said that there’s no point in learning jQuery because JavaScript alone can do all that jQuery can and more.

So? I’m still going to learn it for fun? I’m having a blast with SCSS and jQuery, I don’t care 🤷🏾‍♀️ and I’ll learn the other frameworks and libraries that suits me because I want to. I don’t care if the entire tech community stops using a technology - if it interests me, I’m still going to learn it~!

Also no hate or anything to that person who said that to me - I completely understand your POV on jQuery! 💗✨ When I first read comment, I was a bit down like “oh what’s the point then…” but slapped myself and was like “I’m not learning for them or anyone. This library is cool and I like it so I’m still gonna use it”

Moral of the story: just do you. Do what makes you happy, code what you happy. Don’t be so serious all the time and make stupid dumb programs or games or websites whatever. Have fun in such a hard subject!!!

omg that sounds so cool

one of my friends found radiooooo which is a site that streams music from any country from any decade (well, most countries/decade combos work) and we’ve been digging going on a quest to find what is rad

so far the following is good

50s/60s/70s/80s russia

70s cambodia

20s japan

80s ethiopia

80s india
