love when men cry about body hair bc "it's hygiene" and yet 15% of cis men leave the bathroom without washing their hands at all and an additional 35% only just wet their hands without using soap. that is nearly half of all men. that means statistically you have probably shaken hands with or been in direct contact with one of these people.
love when men say that women "only want money" when it turns out that even in equal-earning homes, women are actually adding caregiver burdens and housework from previous years, whereas men have been expanding leisure time and hobbies. in equal-earning households, men spend an average of 3.5 hours extra in leisure time per week, which is 182 hours per year - a little over a week of paid vacation time that the other partner does not receive. kinda sounds like he wants her money.
love that men have decided women are frail and weak and annoying when we scream in surprise but it turns out it's actually women who are more reliable in an emergency because men need to be convinced to actually take action and respond to the threat. like, actually, for-real: men experience such a strong sense of pride about their pre-supposed abilities that it gets them and their families killed. they are so used to dismissing women that it literally kills them.
love it. told my father this and he said there's lies, damned lies, and statistics. a year ago i tried to get him to evacuate the house during a flash flood. he ignored me and got injured. he has told me, laughing, that he never washes his hands. he has said in the last week that women are just happier when we're cooking or cleaning.
maybe i'm overly nostalgic. but it didn't used to feel so fucking bleak. it used to feel like at least a little shameful to consider women to be sheep. it just feels like the earth is round and we are still having conversations about it being flat - except these conversations are about the most obvious forms of patriarchy. like, we know about this stuff. we've known since well before the 50's.
recently andrew tate tried to justify cheating on his partner as being the "male prerogative." i don't know what the prerogative for the rest of us would be. just sitting at home, watching the slow erosion of our humanity.
#writeblr#warm up#ps edited so it is more clear where “half” of men is coming from:#15% literally don't even touch water#an ADDITIONAL 35% ''wash'' by just running their hands under water WITHOUT SOAP#15+35 =50%#like that is not washing ur hands. go back and use soap#btw the numbers for women are 4% never washing and 15% ''just water''#which is still gross but like. sooo much better yikes#ps i know we're all gay on this site but watching ppl ''correct'' my math on this has been wild#i have a learning disability im genuinely bad at math so i check EVERY time someone corrects me#but no they're just confidently wrong.....#182 hours is a week babes. 182/24 (number of hours in a day) is ~7.6#that's where i got that number from. also from rent we know there's 168 hours in a week.#ALSO btw if u read this and ur response is ''men are also struggling rn tho'' like babe you missed the point of it tho#this doesn't even make fun of men it's legit just pointing out that bigotry against women isn't founded#in anything men actually CARE about . like they don't actually CARE about ''being clean'' when they make fun of armpit hair#or they would be WASHING THEIR HANDS.#men pretend to be rollin' in cash and Apex Predators and instead they are trained to be lazy and unwilling to act in emergencies#i have never and will never make fun of men for asking for more support on important topics like DV and mental health.#this is so clearly not about men; it's about how common just being plainly misogynistic has become.#like they don't try to hide it anymore.

The maths fandom is wild. “Real” and “imaginary” numbers? I think you mean canon and non-canon. You guys seriously go “this is my number oc his name is i and he is the square root of -1” when in numbers canon lore it’s actually impossible to square root a negative but sure whatever. “Complex numbers”? I think you mean a character x oc ship. “f(x) = 3x - 5”? That is self-insert fanfiction.
#(spoiler for the maths finale) 7 eats 9#mathblr#math memes#shitpost#locus other time#this is a joke don’t get too worried about it. I just wanted an excuse to say imaginary numbers are OCs#i would go more in depth but alas. as I’m making this I’m 16 so I haven’t learned all the fun maths lore yet#math#to reiterate: I am aware this is an oversimplification and not how maths works and nothing in maths is canon!#I am not trying to say square rooting negative numbers is stupid or impossible or saying imaginary numbers are a lie or anything like that#I just wanted to have a bit of fun with using fandom terms for numbers (and play off the stereotype of people who police “canon”)#no hate to mathematicians or the field of maths. You guys are cool. Sorry if it came off that way

#actually the reason is that they're often seen as idiots but they just think differently#and also they're pretty much neurodivergent#luffy infodumping about beetles and zoro is like 'uh yeah sure captain' *didn't understand shit but luffy is happy so it's fine*#zoro explaining the most complicated equation known to mankind bc of some dumb new attack and luffy's like#'why are you using letters? math is with numbers haha silly zoro'#they're so real for all of this#zolu#roronoa zoro#monkey d. luffy#one piece

why are PJO characters most consistently measured in scales of Michaels?
Like. this is some of the most specific height information we have out of most characters, besides maybe Percy being an inch shorter than Jason. The Michaels Scale...
#pjo#riordanverse#nico di angelo#michael kahale#michael yew#clarisse la rue#this is some of the most specific numbers we get#also for the record i did the math and inferring based on multiple factors#(average height of a 13 year old boy / average height in 1930s italy)#so implications are: a.) Nico is absolutely never gonna break 5'6''. he is probably 5'2'' at best in HoO#and b.) presuming that. the math does add up that in comparison Michael Kahale is about 5'8'' which would put him at ~50lb heavier than Nic#with the *generous* estimate that Nico is like 120lb. which is average for 5'2''#but knowing that Nico weighs like. Nothing. he is Skin and Bones. lets guesstimate that Nico is 120 soaking wet. hes probably closer to 110#i do too much math for these books. anyways enjoy that. wiki i want the heights updated with sources on my desk by tomorrow /j

0 is a natural number
I think they should stick the heads of people who say 0 is a natural number on pikes outside of the maths department at the local university.

not to be controversial on main, but i really do feel like way more people would enjoy maths if someone properly explained it to them & they didn't have a hanging threat of failing an exam above their heads
#it's genuinely so nice to try mathematics outside of academic setting!#look at me solving numbers' wee riddles three! they are speaking to me!!!!!#it's like being a detective in the world of formulas. liek evolution. like constant battke of survival#everytime you learnt a new tactic to solve a problem. another obstacle appears#me and math are locked in eternal dance where we fight like enemies yet are unable to live without each other like lovers#there's no math without mind being able to percieve. and there's no seeing reality without perceiving maths#AND NUMBERS ARE. EVERYWHERE#don't get me wrong i'm not an analytical kinda person. i was always the english & biology type of kid and physics was my enemy in school#BUT IF YOU LOOK AT IT RIGHT. YOU TOO CAN LEARN TO APPRECIATE MATH#math#ramblings

How many holes does a straw have?
@i-send-you-random-asks
(asking you specifically cause i think you'd have an interesting answer)
Ohhh, yes, this is my question! Thank you, dear!
Short answer:
That depends on your definition of 'hole'. Topology says 1.
Long answer:
Since this depends on your definition of hole, I can think of 5 answers that can be rationalised and make some flavour of sense:
(@marvellouspinecone helped me with some of these a while back and might have additional info, so I am going to credit her here.)
0 holes
You can define a hole as something that makes an object broken, or at least as something you have to put into a finished object AFTER construction. This could be something like a tear in the fabric or a hole you have drilled into the 'wall' of the straw. Ergo, a functioning straw does not have any holes. It looks exactly as it was designed to be.
1 hole
This is the math answer. As said in the infamous post, a straw is 'topologically equivalent' to a torus. To be precise, it is homotopic to a torus.
First question: What is a torus?
Answer: Basically a donut. It looks like this:
[ID: image of a torus. It looks like a donut with a checkered surface. end ID]
Second question: What does 'homotopic' mean?
Answer: This is where it gets math-y technical, but in a way it means that we can continuously transform either of the objects into the other - in a nice way.
Imagine, our straw was made of super-clay: we can't rip it or glue it together at any point, but we can pull and push it together however we like, even changing its density. So we could stretch some parts to become very big and shrink others a lot. We can also bend and twist it a little.
So, we take our straw and we push it together in the direction of its length until the very long straw becomes short like a ring. And then we pull on the 'walls' to make them nice and fat and round. Tada! We have made a donut!
(We can do this in the other direction, too, pull the torus (donut) out long and then make the walls thin - then we get a straw.)
The thing about such homotopies is, they preserve the number of holes an object has. Hence, the straw has exactly as many holes as the torus (donut)!
Third question: How many holes does a torus have?
Answer: In topology, we have something called the Euler characteristic. It is a number that gets assigned to surfaces based on their properties (you can calculate it via triangulation but let's not go there.) A sphere (ball) has Euler characteristic 2. Each hole in a surface lowers the Euler characteristic by 2. The torus (is an orientable surface and) has Euler characteristic 0, so it has one hole.
(If you'd like to have the more exact explanation, it is attaching handles to a surface that reduce the Euler characteristic by 2 and add a hole. And a torus is homotopic to a sphere with one handle attached.)
Thus, a straw has one hole.
2 holes
If we define a hole as an indentation in an object that allows us (or something else) to enter a certain distance into the object, a straw has two holes. One on the top and one on the bottom.
This definition actually makes sense, since we call holes we dig into the Earth 'holes'. In the mathematic sense, they aren't, they're indentations that can (with the super clay idea) be flattened out. But with these holes we don't care about whether it will lead somewhere or just have a floor somewhere at the bottom, you can go in, so it's a hole.
If we forget about the fact that the straw leads 'one hole into the other', so like, if we were very small (or the straw very big) and we would merely walk across the outside and look into the holes, we would find two holes on the straw, one on the bottom, one on the top. If we don't enter, we wouldn't even know they were connected.
With this definition you have to be a little bit careful about when you start calling something a hole. I would reckon there needs to be a certain percentage-relation between depth of hole vs circumference of entrance to hole before you call it such. And maybe also something about size and shape and sharpness of edge - like, you wouldn't call a valley a hole, probably? But like, the straw fulfils the requirements of this hole easily, and twice.
3 holes
Okay, this one is merely for fun and play, don't get mad at me. But, say we define a hole kinda like above, as an entrance to the inside of an object. And we further define hole as any way through an object. Then we end up with something I like to call a 'hole-interval' through the straw.
So, we have one hole (rim at the top) to get into the straw, one hole (the straw, basically) to get through the straw and a third whole (rim at the bottom) to get out of the straw.
This is nonsense, obviously, but I like it, because there is a very nice mathematical feeling to it, resembling a closed interval. A closed interval [a, b] is just one object, but it has three parts that are often regarded independently of the others: the open interval (a, b) in the middle and the edge points {a} and {b}. For example, if you were to test the continuity of a function, you would often regard these three cases separately. So, in a way, there is beauty in regarding the 'three holes' of the straw as separate as well.
Infinitely many holes
This one is kinda nonsense as well, but I like the implications. If we define a hole as any instance of an object that is part of a tunnel through the object - I am using the word 'tunnel' here because actually, that tunnel would be the one hole in this case but for the sake of the definition, it can't be - then a straw is an infinite number of holes, stacked on top of each other. It is important to notice here that a hole cannot possibly have any depth in this case, just like the top and bottom holes in the last case.
This leads to two likely interpretations:
A) We have a hole at any real number (if we consider the straw as an interval along its length again). Then the straw would be made from uncountably infinitely many holes - which I think is an awesome concept.
B) We have a hole at any rational number. This would only give us a countably infinite number of holes in the straw and since Q is dense in R (don't worry about what that means), it would LOOK like the whole straw is made of holes, when in reality most of the straw would actually NOT HAVE ANY holes in it. Now isn't that the best thing you have heard all day?
And the best part : By this definition, not only would any straw be made of infinitely many holes, but any object with a hole in it would have infinitely many holes in it. Remember, for this to make sense, we needed to have holes with 0 depth. But any hole in reality has some depth. Punch a hole into a piece of paper: BAM infinitely many holes stacked on top of each other! :D
What have we learnt?
The most likely answers are 1 hole or 2 holes, depending on whether you take a more mathematical or more language-oriented approach. I think those were the two opinions most vocal in the original post as well.
But if you want to have fun, you can come up with very nice concepts and definitions to count holes by that give you a range of correct answers. Just make sure to think of the implications :)
#Thank you for this question <3#I think you can tell I had a blast#On a related note: me and my friends were talking about the euler characteristic of the Earth the other day#Bc in meteorology you often consider the Earth as a torus#But with all the tunnel systems it is more likely to be an n-torus with n the number of holes and n being a VERY large number#Instead of - what you would initially guess perhaps - a sphere#math

How much information from Unlimited Void has Megumi suffered?
I sat down and calculated the information/damage that Megumi had to go through because Sukuna had him shoulder the adaption of Mahoraga's wheel while inside the Domain Clashes (DC).
Relevant Information from Gojo's Domain Expension in Shibuya: it lasted 0.2 seconds, forced 6 months worth of information into non-sorcerers' brains and had them in a two month coma as a result.
1 second of Unlimited Void = 30 months of information
During their DCs, which happened 5 times, Gojo's sure-hit effect enveloped the entire domain while Sukuna's SH enveloped the entire domain except himself. This led to Sukuna being hit 5 times by UV but because he used the Ten Shadows Technique as a medium, he was able to redirect UV onto Megumi, making him the target of the SH.
How many seconds of UV was that? For the last three DCs we have concrete numbers, the first two are estimates by me:
DC: 20 seconds
DC: 120 seconds
DC: 189 seconds (3m9s, counted by Mei-Mei)
DC: 189 seconds (3m9s)
DC: 160 seconds (told by the narrator)
In total, Megumi was hit definitively by UV for 538s with an estimated 140s on top. Therefore, the months of information that was fed to him are: 16,140 months (definitive) + 4200 months (estimate). In years, these are 1,345 years (definitive) and 350 years (estimate).
Megumi was hit by Unlimited Void with about 1700 years worth of information
That's the amount damage Megumi had to shoulder so that Sukuna could adapt Mahoraga to UV and protect himself. But because Megumi was only a soul at that point, he didn't die. We know that curse brains suffer less from UV than human brains, so a soul on its own most likely doesn't come out with lasting damage but only to the *body* of the soul.
What kind of effect this suffering will have on Megumi's mental state is anyone's guess. My personal theory on this is that Megumi will actually be able to understand that infinite amount of information and grow from it instead of receiving brain damage like Sukuna.
#jujutsu kaisen#jjk#fushiguro megumi#sukuna#gojo satoru#meta#theories#I made several math errors along the way#like forgetting to multiply the 6 months by 5 to get a whole second#and for some dumb reason I also calculated a year as having 24 months#the numbers just kept rising I want to say#Megumi's suffering just became bigger and bigger

The language part (ie the Main Actual Game) of Chants of Sennaar is very fun don't get me wrong - figuring out when a radical means person, or signifies a verb, etc etc - but the number system is absolutely fascinating
#like it's base 10; this is a language game not a maths one#but the way the numbers are written is like. this would make more sense with images but I'm in the tags now#take the number 1342. that's 1x1000 3x100 4x10 2x1 that's how we write it#instead of place columns this system uses quadrants#there is a central thick line. bottom right is units; bottom left tens; top right 100s; top left 1000s#this is a fun and compact way to write a four digit number!#but what about a 5 digit one? 6? bigger?#I don't think the game needs numbers that big but I'm going to follow this train of thought to a conclusion - just use another line+quadran#fairly normal idea- run out of space on your first one? add a second!#but where it gets fun is that means; putting it back into base 10 numerals and keeping the digit separation the same; a long number might b#grouped like: 1 4637 3427#and if you are used to the western way of grouping digits that looks weird! (we do 3 234 638)#they work in myriads! isn't that neat!#chants of sennaar
