i’m starting a collection

Pick a point inside a triangle and drop perpendicular projections onto the sides. These define another triangle. Repeat, with the same point but within the new triangle. Do the same thing once more. The fourth triangle now has the same angles as the first one, although it’s much smaller and it’s rotated.

I had an exam yesterday, one more to go. it was the written part, so 12+ hours of solving problems, exhausting just like before. I completed all of them, but of course I am not sure if my solutions are correct, I will find out on monday. I'm proud of the progress I've made

right now I'm studying for the second part, so the theory-oriented one, I can barely focus because I've already learned those things and now I have to relearn them again

I'm trying to prove all the theorems on my own. partly to see how much I remember, partly to see how much I'm willing to improvize. as they say, if you're using too much memory then you're doing something wrong so I'm hoping to be able to come up with the proofs without memorizing anything new

my technique for studying the theory for the exam is to first test myself on how much I remember by trying to write everything down and note where I'm unsure or don't remember at all. then I read the textbooks starting from the worst topics up to the better ones. when I encounter a long complicated proof I am trying to break it down into steps and give each step a "title" or a short description

for instance, the Baer criterion featured in the photo has the following steps:

only do "extenstions on ideals to R→M ⇒ M injective"

define the poset of extenstions of A → M, A ⊆ B and a contrario suppose there is a maximal element ≠B

use the assumption to define an ideal and a submodule that contradicts the maximality of the extension

it is much easier to fill out the details than to remember the whole thing. this is probably the biggest skill I acquired this semester, next to downloading lecture notes pdfs of random professors I find online lmao

a friend suggested that I could make a post about tips for reading math textbooks and papers. as for papers, I don't have enough experience to give any tips, but I can share how I approach reading the books

a big news in my life is that I got a job. I will be a programmer and I start in march. at first I am going to use mostly python, but in the long run they will have me learn java. I'm excited and terrified at the same time, this semester is gonna kill me

for the sake of an updates to this, I didn't get 100% on that topology test. I got 85%, which was the third best score. I finally scored the highest possible final grade on that subject, so I'm satisfied. fuck I love algebraic topology so much and I think she loves me

oh and I scored fucking 54% on the analysis test. I think I had a mental orgasm when I found out about that lmao it felt so good. I finished the course with a grade of 4 (idk if it's universal, so 2=the lowest, failed, 5=the highest) which is the best I ever got in the analysis course

topology and analysis tests are over, both went I think alright

if I don't get 100% from topo I'm going to be very frustrated, because I studied hard and acquired deep understanding of the material – so far as to be able to hold a lecture for my classmate about any topic

analysis ughhh if I get ≥40% I will be overjoyed. but that's just the specifics of this subject, you study super hard and seem to be entirely ready, you solve all of the problems in prep and then best you can do is 40%. my best score so far was 42%, so anything more than that will be my lifetime record lmao, I want this so bad. I solved two problems entirely I think, which should give 40% already, and some pieces from two more, chances are I get 50%, which would be absolutely amazing

here are some pictures from me transforming math into an art project

stokes theorem

topology

I was thinking about how annoying I find what people say to me when I tell them that I'm not happy with how I'm doing at math. their first idea is to tell me how great I am and how all I do is good enough and shit like that. it doesn't help, it just feels like I am not being taken seriously. when I barely pass anything, am I really supposed to believe that everything is actually good? it feels like they skip getting to know my situation and just tell me what they would tell anyone, automatic

when I try to calm myself down and think something that will keep me going I don't try to force myself to be happy, fuck that, not being content with one's achievements is very fine, I believe not being happy all the time is fully natural and all that positivity feels so fake

instead what seems to work is asking myself where the rational threshold of being ok with how I'm doing is. the thing is I will never be satisfied, whatever I have, I always want more. but I can set the limits in advance and that stops me from falling into self-loathing loops

although what has really changed the game for me was getting a few good grades, finally I am achieving something, anything. people tell me that I should learn to be alright without this external reliance on achievements but how am I supposed to do that when the source of my low moods is precisely getting less than I want? I don't understand why I should brainwash myself into thinking that this is actually not what I want. the trick here is to separate the goal-orientedness from the sense of self-worth. the groundbreaking realization of mine was figuring out that I believe I deserve more than I get, that's why I am unhappy. so now that I am getting what I think what I deserve I obviously feel much better

my euclidean geometry journey will be over soon and the start of the semester is so close, it's kinda scary

recently I stumbled upon someone's post with a time-lapse video of their study session. I liked it so much that I decided to make mine

this is me learning about the snake lemma and excision

the excision theorem is the hardest one in homology so far btw, I spent about 4 hours on it and I am barely halfway through. I like the idea of the proof tho, it's very intuitive actually: start simple and tangible, then complicate with each step lmao

I realized two things recently. one of them is that deeply studying theorems is important and effective. effective, uh? in what way? in exams we don't need to cite the whole proof, it suffices to say "the assertion follows from the X theorem"

yeah right, but my goal is to be a researcher, not a good test-taker, researchers create their own proofs and what's better than studying how others did it if I am for now unable to produce original content in math?

the second things is that I learned how to pay attention. I know, it sounds crazy, but I've been trying another ✨adhd medication✨ and after a while I realized that paying attention is exhausting, but this is the only way to really learn something new, not just repeat what I already know. it made me see how much energy and effort it takes to make good progress and that it is necessary to invest so much

I am slowly learning to control my attention, which brings a lot of hope, as I believed that I had to rely on random bouts of hyperfocus, before I started treatment. I am becoming more aware or how much I am focusing at the given moment and I'm trying to work on optimizing those levels. for instance, when I'm reading a chapter in a textbook for the first time, it is necessary to remember every single detail, but wanting to do so consumes a lot of energy, because it means paying constant attention. it is ineffective because most likely I will have to repeat the process a few more times before I truly retain everything. being able to actually pay attention at will sure does feel good tho, as if I had a new part of my brain unlocked

I am solving more exercises for algebraic topology, procrastinating my lecture prep lmao. I am supposed to talk about the power of a point and radical axes, I have a week left and I can't force myself to start, because there is so much good stuff to do instead

I have a dream to produce some original results in my bachelor's thesis. it may be very difficult, because I hardly know anything, that's why I'm calling it a dream, not a goal. the plan is to start writing at the end of the semester, submit sometime in june

I spent last week at the seminar on analysis and oh boi, I will have to think twice next time someone asks if I like analysis. the lecturer who taught me at uni had a different approach than the "classic" one. we did a little bit of differential geometry, Lie groups and de Rham cohomology, those are the things I like. meanwhile at the seminar it was mostly about analytic methods of PDEs, the most boring shit I have ever seen

complex analysis will most likely be enjoyable tho, I'm taking the course this semester

for the next few days I need to force myself to prep that damn geometry lecture. other than that I plan to keep solving the AT exercises and maybe learn some more commutative algebra. I wish everyone a pleasant almost-autumn day 🍁

well, google, one of them is a giant fuckin red dog

I know your thesis was about something to do with algebraic topology, may I ask what exactly it was about?

(and congrats to you getting your bachelors degree and into a masters program)

(thank you!)

my thesis was about an open question regarding a certain skein module of tangles on 2n nodes. the conjecture is that the module is free and in my thesis I constructed a generating set that is free for n=2,3 (direct calculation) but I have yet to prove that for a general n. if you are interested I can send you the paper in which the question was posed, all the details are explained there and would be hard to write down here without tex lol
