My Love For Topology Is A Very Concave Function With A Very Positive Derivative

omg so that's why so many empty blogs follow me. I've been blocking them at first assuming that they were bots, but at some point the usernames started sounding way too normal-human-like, so I stopped, my instinct told me something else was going on. lemme just unblock all the empty blogs now, damn, I'm so sorry to everyone who wanted to follow me but was blocked out of habit!!

fun fact!! it turns out that now when u make a new blog, tumblr forces you to follow 3-4 people before you can change your icon or modify your blog in any way!! this, of course, means that, yes, some of the "potential bots" many of us have been automatically blocking could have possibly been genuine new users who were only just seconds in to having an account!!! tumblr is literally screwing new users over!!!!

Real estate agent, 5 minutes into the meeting with a topologist: So, when you were talking about "contracting" a "house with two rooms",

I read this and it got me thinking that it's funny how many goals and standards people tend to have. my only goals are to have fairly good health and to improve my math skills constantly. maybe it's my obsession, maybe it's the fact that I just gave up long time ago on femininity, social skills, so called emotional intelligence and how I present to other people

besides… why does this sounds like I'm supposed to only date men lmao

if you don't want to learn tikz but still need them arrows, check out quiver. it's super useful for complicated and unconventional diagrams

Learning LaTex has been a way more pleasant experience than I thought it would be this stuff is way simpler than it looks and the results fuck hard

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

Here’s a long but important comic for you <3

Accepting ourselves the way we are means we allow ourselves the things we need to make life a little easier. You don’t have to fight it, it’s ok have different needs to others. You are worthy of kindness, so be kind to you <3

love from the sad ghost club <3

I have a possibly unusual question. since I left high school and was no longer being forced to read I completely stopped looking at fiction and other books that are not math textbooks. this is partly because I fucking hated reading as an activity – I have adhd and asd, so not only my attention regulation causes a lot of problems, I also struggle with visualizing what's happening and imagining/undestanding the intentions and mindsets of the characters. now, I am properly medicated so attention isn't as much of an issue anymore and I remember enjoying some of the books I've been forced to go through. I miss reading, overall it had a positive impact on my thinking process, I miss analyzing the human experience, so to speak

I liked Dostoyevsky, Vonnegut, Philip K. Dick, Huxley, Kafka and some other "philosophified" authors. I also enjoyed war-themed books in general such as all quiet on the western front, and everything related to the soviet union

finally, my question is, what would you recommend for someone with this taste, who also likes math¹, has a hard time with visual imagination and people but enjoys analyzing human experience, who would possibly like to see a represenation of themselves in the characters of the novel? I would love to rebuild my reading habits, but I am lost as to where to start so I don't get discouraged

¹ I included math in here because maybe there is a book about what it's like to be a mathematician (or a scientist of some kind) that give some existentialist vibes or something, if it exists I want to read it lol

abstract algebra things that are good:

groups. i love taking inverses

fields. i LOVE taking inverse

banach algebras. i love having a notion of distance, and also being a complete space

lie groups. i dont know anything about them yet. but they seem so cool. technically groups

abstact algebra things that are bad:

rings. god i hate rings so much. theres like a thousand different kinds of rings, some of which are subsets of each other, and some of which have different names but are actually the same.

Weaving Stereographic Projection

I made a stereographic projection by weaving paper strips!

Here's a Julia package for the computation of the shapes of the paper strips.

some more animation: how secant-teenager becomes tangent-adult

also! it illustrates a well-known inequality of a differentiable convex function and its tangents & the monotony of slopes
