    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?”

      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?

      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. trans is very trendy right now and it’s become on point for kids to identify as trans or some other non binary sexual identity. whether or not it sticks in the future, not sure. there is a counter-movement as well towards reinforce trad gender binaries in the dating sphere for sure. i’ve noticed as i age that a lot more people start caring a lot more about trad gender role stuff than they did in my 20s.

        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

      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.

        Gender isn’t part of biology (as a social construct) but the complexity of sex absolutely is.

        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”).

      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.
