i think that if more people were exposed to advanced math there would be a reactionary trend of people going around and asking mathematicians “what is a number?”

sort of like the reactionary trend of pulling your kids out of school because Common Core has changed how math is taught so critical thinking and conceptual understanding is incorporated, rather than teaching math by rote memorization?

I'm shocked that the US only adopted this in 2009. I'm pretty sure my mum, who went to primary school in the 70s, recognized number lines when I was taught to use them on 2005ish. I'm having a hard time imagining how else you'd explain it.

look, we work very hard on being reactionary here in the U.S., we're a world leader in reactionary politics, and not teaching math well is crucial to keeping a vibrant ~~slave~~ worker population, otherwise they might start, you know, thinking for themselves

So, I understand that the number line is a way to conceptualize relational distances between numbers, but in that example I'm struggling to see the relation between 57 where the line ends and 111, the answer. If you have insight, do you mind elaborating?

Edit: actually... Aren't the numbers they wrote in on the line WRONG? Why did they go down by 20 to 107, then by 10 to 57 arbitrarily? If you do 10 instead, then increment by 1 to 111... You get the answer. Did the person solve it wrong and put the right answer to get people outraged?

Ehh not really its just to old if a concept for us to be appaled by that. Its not 15 century for imaginary numbers to cause riots.

There is a slight difference though in that complex numbers are a part of math but gender isn't really a part of biology.

Also the mathematicians wouldn't decline to give an answer.

Also the mathematicians wouldn’t decline to give an answer.

Are you sure? I only minored in math, but even I would struggle to provide an answer to this. It would have to be something incredibly vague, like "a number is a mathematical object that has certain consistent properties relevant to the field of study." Because otherwise you get situations like "is infinity a number?" and you can't answer categorically, because usually it's not, but then you look at the transfinite numbers where you can indeed have omega-plus-one as a number. And someone asks if you can have an infinite number of digits to the left of the decimal place, and you say "well, not in the reals, but there are the P-adic numbers..." and folks ask if you can have an infinitely small number and you say "well, in the reals you can only have an arbitrarily small number, but in game theory there are the surreal numbers, where..."

So yeah, I'm not sure "what is a number" is even a math question. It's more a philosophy question, or sometimes a cognitive science question (like Lakoff and Nuñez's "Where Mathematics Comes From").

Can confirm. I was already struggling. But I just straight up refused to math with i

have you taught?

anytime you give people a new metaphorical hammer, they want to go around banging everything they can with it. then they get bored and forget about it.

pop psych is a great example. people love to go around diagnosing everyone with whatever new schema of diagnosis is popular and trendy.

I was going to make a comment about surreal numbers not being numbers. But I did a bit of fact checking and it looks like all of the values I was objecting to are not considered surreal numbers, but rather pseudo numbers.

I find this outrageous. Why can't ↑ be a number? What even is a number that would exclude it and leave in all of your so-called numbers?

Do the two tails left of M and right of F mean there are males more male than cis males, and similarly with females?

[–] Kazumara@discuss.tchncs.de 0 points 1 day ago (1 children)

I don't think it's an accepted term anymore, but you reminded me that they used to call the triple X chromosome syndrome by the term Super-Female-Syndrome.

Probably not what the author intended though.

...

I am a horrible person, but the only thing I can think of reading this is a small-circuit pro wrestling event where all participants have this set of chromosomes, billed as 'The Triple X Throwdown', for the title of Supreme Female.

Yes, hyperreal genders do exist, but are not stable outside lab conditions.

I would submit David Bowie as a counter example.

[–] SeptugenarianSenate@leminal.space 0 points 23 hours ago (4 children)

Are we sure he would describe himself as either consistently “stable” throughout his experiences? Alternately, he might also protest to feeling as though his existence and the context around it might be well described as a sort of experimental setting, albeit not contained within a traditional laboratory setting.

Any world famous musician who not only survives their 30s but is relatively alive and kicking for decades later I would consider to pass the first condition, considering the track record for individuals experiencing that volume of fanatic obsession at young ages.

Well, clearly. If you define a male characteristic as something that's more common in men than in women and vice-versa, then e.g. being tall would be a "male characteristic".

Height isn't a binary thing with men being exactly Xcm tall and women exactly Ycm, so there's people who have more of said male characteristic and people who have less. And you also have women who have more of this characteristic and some men (e.g. there are some women that are taller than some men).

The same can be done for every characteristic that's associated with a gender. Genitals are on a spectrum (large clitoris vs micropenis), fat distribution is on a spectrum (e.g. there are men with breasts and women without), body hair is on a spectrum, hormone distribution is on a spectrum and so on and so on.

If you take a lot of characteristics at once it becomes clear in most cases whether the person you are dealing with is a man or a woman (though there are some where that's more difficult or impossible), but if you take just a single characteristic (e.g. height) it's impossible to say whether the person you are dealing with is definitively a man or a woman.

It means that traditionally understood cis male can still have some female characteristics (no facial hair, higher pitched voice, bad at driving) but some males will have none.

[–] dandelion@lemmy.blahaj.zone 0 points 1 day ago (7 children)

the peaks do not designate "cis", you can be cis and fall anywhere on the chart - being cis is about the sex you were arbitrarily assigned at birth.

And when doctors change assignments, it's really unclear whether you're cis or not if you transition - e.g. a baby assigned female at birth who is then weeks later assigned male at birth later transitions to be a girl, she was originally assigned female at birth - is she trans or cis?
