Ragebait ideas for your math friends: tell them that their research area is just a special case of your much cooler research
Category theorist speedrun social pariah status strategy.
Category theory is just a special case in my much cooler area of research, mathematical logic, in which we analyze the notion of a mathematical "theory" in abstract. Category theory is just a manner in which words and symbols are used to encode meaning, convey information, and draw inferences.
Pre-schooler destroying the whole mathematical community:
All mathematics is just specialized counting to 3

I haven’t seen this in years and yet it is burned into my memory forever.
This is on the short list of Eternal Reblog because it’s fucking legendary.

I crocheted a series of hyperbolic planes and strung them up into a garland. Each module is one more round than the one before, and each round has twice the stitches as the round before.
I made eight iterations; the largest one took an entire skein of cotton yarn. I really liked how this shows the change in curvature as cross section of the plane expands.

This is a really fantastic return to form for this genre of post. In recent years there's been less and less effort put into this vital aspect of internet culture, it's nice to see a return to the truly artisanal work of the late 00s.
Now THIS is what the internet exists for. I was LOCKED IN the whole time.
MATH QUESTION!!!!!!!!!!!!! 🔥🔥🔥♾️♾️♾️🧠🧠🧠‼️‼️‼️🔥🔥🔥
The other night I had a fever and I was delirious and while I was trying to fall asleep I had some sort of math related epiphany and everything made sense but now that I am not having a fever dream anymore I can’t get back on that train of thought. Disappointing.
Anyways do you think that the difference between 0 and 1 is greater, less, or equal to the difference between 1 and ♾️? I can see it all three ways and I’m curious what other people think. I’ve asked a few people so far, and the answers are varied.
My dad says less, my mom says greater, the engineering professor from UBC (University of British Columbia) I contacted said a lot of things I didn’t understand and I’m still trying to figure out what his conclusion was but I think it was something along the lines of “it depends”. My 7 year old cousin didn’t know what infinity was but once I explained she said less. My cat’s response was too abstract for me to understand but I think he’s leaning towards greater. My 19 year old cousin says they’re the same, if you can consider 0 and infinity to be opposites. During my fever dream, I was leaning very strongly towards greater but I don’t entirely remember why.
It’s an interesting question because there’s so many different types of 0s and ♾️s and so many different ways of thinking about numbers and what 0 actually means and stuff.
What do you think
0 to 1 is a greater difference
0 to 1 and 1 to ♾️ are the same
1 to ♾️ is a greater difference
That’s scary … I don’t know …
Also!!! Please put your reasoning in the notes!!!! I want to see your thought processes!!!
Like, you can multiply 1 to get to ♾️, but 0 can never be multiplied to get to 1. In terms of exponential growth, I feel like 0-1 must be greater, because the distance is impossible. Is the difference between having nothing to having one thing the same as having one thing to having infinity things? On a number line, it’s obvious that 0-1 is a difference of 1, whereas 1-♾️ is a difference of ♾️ minus 1, so 0-1 must be a smaller difference. There’s an infinite amount of numbers between them both. They’re reciprocals. 0 can be real, where ♾️ can’t. It’s so weird. The answer is obvious to some people, but they come up with different obvious answers.
Pretty sure this is proven to be, ‚indeterminate‘ for the same reason x/0 is.
Cantor set - Wikipedia
Specifically under: properties: cardinality
We can argue that the amount of numbers between 0 and 1 is „A“
(also this will be in base 10 so an answer can be derived, but base 10 is arbitrary and a different base with equal viability will give a different answer, ergo indeterminacy)
And amount of numbers between 1 and something is „B“
For example:
A={0,0.1,0.2,0.3…0.9,1.0}
B={1.0,2.0,3.0…9.0,10.0}
Now B{[1.0,2.0]} contains all of A.
B/100={.01,.02,.03….09,0.10}
Now the magnitude of a set should not impacted its length:
„If I have 10 items, but they now have a different size, how many items do I have?“
But B/100 is now contained by A{[0.0,0.1]}
We can establish B= an infinite set which contains goes from n=0 to n=set_index of :
10^-(Ceil(set_index+epsilon)/10) •each number of B‘s. infinite set based on n
Where the above has equal length to the set at hand and when multiplied by the 10^ (Ceil(highest possible set index + epsilon)/10) the originally B set will be scene in this magnification.
When we have B zoomed out like this, B becomes a subset of A
.This is arbitrarily recursive, for you could throw this zoomed out B set to be arbitrarily smaller or larger depending on modular system, and arbitrarily smaller or larger than the A set, which means you could choose by what difference any given B set is larger than any given A set (negative meaning smaller than).
This can be done because you are treating infinity like a number rather than a rate, which is why calculus works, but this doesn’t.
Note: these problems arise even if we don’t have B‘s upper bound being infinity, and because you’ve merely said infinity, and it’s undefined in 2 ways that do not cancel eachother out.
So the correct answer is:
„That’s scary… I don’t know….“!!!

being alive is like,, being so full of love and so full of loss at the same time. a lot to carry around either way.
average first sentence of a math wikipedia page:
A snorkle basis is a particular sort of set that has some properties and is generally "nice" (in a rigorous sense) and can do many things and is very practical.
you forgot the best part tho
(via @butchmuppet)
no lie, the second half of this post really helped me put a different perspective on my life and greatly the decreased the anxiety i have about my life to come
I learned a new concept
Graceful degradation is the ability of a computer, machine, electronic system or network to maintain limited functionality even when a large portion of it has been destroyed or rendered inoperative. The purpose of graceful degradation is to prevent catastrophic failure. (Tech Target, first result on the search engine)
Literal opposite of planned obsolescence. I love you graceful degradation.
Oh neat the first time I heard of the concept the guy described it to me as "catastrophic functionality".
He was talking about it in the context of designing robots that would go in and stop nuclear reactor meltdowns, something that would 100% destroy the robot, but they would be designed to keep functioning and fighting the meltdown for as long as possible. He had some designs where over 80% of the robot has died and it was functionally dragging its corpse around by its one working arm because one more minute of functionality might save thousands.
I've been having a few bad years mental health wise, and thinking about those robots a lot .
This is also why NASA missions usually keep going so long after schedule. They are *masters* of graceful degradation, able to keep machines limping along on minimal power and after sustaining heavy damage
what will it be, boss? the comfort of misery or the pain of change?
The Department of Education worked with the far-right Family Research Council to officially designate March 12th as Detrans Awareness Day last year. But what actually leads people to detransition? It's not regret, but social stigma, incited by the very figures who claim to protect detransitioners. I want to hear their stories describing how the current moral panic influenced their decisions.
i hate that concerns about urban gardening/foraging safety is often met with "What are you, a cop?" scorn. I believe it's a suspicion of anything that hinders the punk/anti-system urgency to jump in immediately and do whatever feels right.
Safety, ethics, and sustainability are all a part of urban gardening and foraging. I'm sorry that means you need to do homework before you can do anything, I know that sounds lame. But life is complicated.
I know anti-intellectualism is viewed as activist these days, but like, surely you don't want to literally eat lead, right?
Let’s check in and see how those rascally solarpunk kids are doing, surely they’ve learned by now that…..
Daily reminder: Leafy greens like kales uptake all those delicious heavy metals in urban soils like lead and cadmium.
Don’t eat sidewalk-crack kale.
