Hey Students, Here’s A Pro Tip: Do Not Write An Email To Your Prof While You’re Seriously Sick.

What's the beef between engineers and physicists and even mathematicians.

Why physicists mock mathematicians: Because playing 51 dimensional chess against your own brain seems silly to us when there’s a whole cosmos to explore.

Why mathematicians mock physicists: The universe can only be understood because some nerd spent the time playing 51 dimensional chess and in the process they created some useful stuff for the physicists to steal and abuse the hell out of.

Why everyone mocks the engineers: π=e=3 is an abomination before God and those pencil pushing dorks make more money than us so we feel the need to vindicate our $75000 student debt.

maybe once a month is a bit too seldom to post? I kinda want to form a habit of romanticizing my academic life, I see all those studyblr accounts with beautiful photos of their desks and notes and I'm pretty sure those images exist in their minds as well

maybe one day I will be considered studyspo lol

I'm just starting to work on some geometry problems for today, haven't yet decided what I will focus on, but there is this one problem that haunted me when I tried to sleep yestarday:

given a triangle ABC with ∠A = 60°, let P be a point in the interior of ABC such that ∠APB = ∠APC = 120°. prove that ∠APX = 90°, for X being the circumcenter of ABC

it's supposed to be solved using spiral similarity, which is a composition of a rotation and homothety. there was another problem that was listed as "spiral similarity exercise", but I proved it with angle chasing exclusively, creating some nasty drawings in the process

other than geometry I'm studying homology, at the moment the basics of homological algebra, such as the first proofs by diagram chasing and exact sequences

I made some notes for exact sequences induced in homology

my perspective on doing math is slowly changing I think, I feel inspired to search for problems that I would like to solve. I noticed that I have this mental block: before I start doing math for real, I need to learn all the theory. which is absurd, you can never learn all the theory

sure, obtaining truly groundbreaking results requires years of learning theory and mastering tools if you want to specialize in algebraic topology and geometry, but the mindset I have creates the comfort zone of "play safe, just read your textbook, no challenges for now" and I'm starting to see beyond that

right now I'm taking my first steps into understanding that reading textbooks and learning how to solve basic exercises is not enough. they are just methods that are supposed to help my creativity and curiosity do their thing. essentially what I've been doing so far is not math, merely the preparation to do math in the future. no wonder I've been feeling so bored recently, all I'm doing is just learning basic tools. the idealist in me is asking to be unleashed

I feel like I'm about to see something much bigger than me

from now I’ve got to start chasing regular discomfort, because otherwise comfort isn’t comfort but stagnation. you can’t have one without the other. to be challenged is to grow and it’s the only way to actually feel at peace

hey netizens! i'm not sure how many people are aware, but youtube's been slowly rolling out a new anti-adblock policy that can't be bypassed with the usual software like uBlock Origin and Pi-Hole out of the gate

BUT, if you're a uBlock Origin user (or use an adblocker with a similar cosmetics modifier), you can add these commands in the uBlock dashboard (under My Filters) to get rid of it!

youtube.com##+js(set, yt.config_.openPopupConfig.supportedPopups.adBlockMessageViewModel, false) youtube.com##+js(set, Object.prototype.adBlocksFound, 0) youtube.com##+js(set, ytplayer.config.args.raw_player_response.adPlacements, []) youtube.com##+js(set, Object.prototype.hasAllowedInstreamAd, true)

reblog to help keep the internet less annoying and to tell corporations that try shit like this to go fuck themselves <3

lmao I just imagined a situation in which someone wrote me a message about math (is math a fandom?) and after realizing that I am an adult decided that talking to me about math is suddenly dangerous, kinda funny

on a serious note, I don't have anything to add, the responses above do a very good job at showing why this is an insane thing to expect from people

@ my fellow adults who use tumblr a lot:

can you PLEASE put your age in your about/sidebar and make sure it’s accessible on mobile. imo if you’re an adult esp 20+ it’s a little weird that you wouldn’t have your age readily available on your blog. if you’re reading this now and you don’t have your age listed, please rectify that. i feel like teenagers get lured into talking to adults in fandom/lgbt spaces that they may not have intentionally sought out because they think they’re talking to other teenagers, and this can lead to a lot of other – much more insidious –problems

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 a lot of headaches recently, idk why. probably something to do with muscle tension, because my back, neck and jaw just lock up sometimes to the point that every movement hurts. I need to see a doctor about it, maybe I injured something or there is some other underlying cause

I wasn't very strict with studying this week, because a lot of stuff we did was a review of what I already knew but obviously it needs a refresher. if I keep ignoring it, I will end up in a situation where I won't know what's going on at all

I picked up some side hustles along the way, one of which is reading the extra topics from hatcher. one of the lecturers recommended a book to me, about galois theory in the context of covering spaces, I'm reading it right now, seems pretty good

tomorrow I'm seeing my advisor to discuss my progress with solving the problem for my thesis. I think I found the basis for the module, at least I proved that the set I chose generates all the other elements, remains to show that it's linearly independent. the second part of the question is the rank of the module, which is how an algebraic topology problem turned into a nasty cominatorics problem eh

today I completed the first "serious" task for my IT job, which was translating the code from java to python. I have never seen java before, but it looks a lot like c++, so I managed. I wrote 500 lines of code but I haven't tested it yet so debugging might be very painful. lol I guess that means I shouldn't say I completed the task

I am wondering if I should go to a conference, I have until the end of the month to submit a presentation. I am not sure if I can handle a trip to another city, it would be in a month, so there is no way to predict how I'll be feeling. this week I am giving a presentation about some knot theory (skein modules, bracket and jones polynomial) and it's a good pick for the conference too, which makes it a really touch choice as the hardest part will already be done. idk I guess I'll toss a coin, like I did about the IT job lmao

other than that, big thanks to everyone who interacted with my post about book recommendations! there are many great suggestions, it turned out much better than I expected tbh, I thought I would get like 2 or 3 notes. I will post a list of the books mentioned in that post, so it will be easier to find for anyone interested
