  • they’re supposed to all be versions of that one, it’s just not always very easy to see how - joke was mainly about that. category theory calls things compact if they’re “small” in a very particular sense. algebraic compactness also has nothing to do with the topological notion, at least on the surface (abelian group that’s a direct summand of every group containing it as a pure subgroup). basically, every area of math where the topological notion makes no sense will invariably call something compact eventually, because mathematicians can’t resist.

    sometimes if you squint you can see how it relates back to the topological notion but frequently it’s anything but obvious if you don’t already understand the field - which means when you’re trying to work things out for yourself, you just have to treat it like one more definition of the same word until you finally get it one day.

    I think it’s easier if you have a prof who can just make the analogy clear from the start.


  • it’s worse than different languages. they use the same words to mean entirely different things. so you can say stuff from the same lexicon that means entirely different things to different mathematicians. there are supposed to be analogies that help you translate but jfc I swear to god if I hear one more definition of compactness I’m going to cry. no I’m not going to learn more category theory to understand how I can use a sheaf to translate the different notions because that also doesn’t mean what I think it means. shut up shut up shut up words mean things. next you’re going to tell me red is blue because color theory staaaahp

    self-teaching math is a pain in the ass









  • fwiw, commutativity didn’t really get specifically called out by mathematicians until they adopted some kind of symbolic representation (which happened at vastly different times in different places). without algebra, there’s not much reason to spell it out, even if you happen to notice the pattern, and it’s even harder to prove it. (actually… it’s absurdly hard to prove even with it - see the Principia Mathematica…)

    these algorithms are clearly not reasoning but this isn’t an example. yes, it seems obvious and simple now but it short changes how huge of a shift the switch to symbolic reasoning is in the first place. and that’s setting aside whether notions like “memory” and “attention” are things these algorithms can actually do (don’t get me started on how obtuse the literature is on this point).



  • setting aside the capitalist-laugh for a sec…

    hinduism doesn’t have a religious objection to alcohol? it’s a social objection - it makes you behave like an ass. there are some philosophical points like how it makes you less human and more animal because it clouds the mind and brings out your baser nature. there’s no religious prohibition that I’m aware of. some sects of Brahmins might treat it as a religious prohibition but there’s no shot this is any kind of blanket ban by the religion as a whole. it’s not very prevalent because there was a religious prohibition by the Mogul empire for a very long time.

    people try to treat Hinduism like it’s one religion with a completely unified and consistent belief system when it’s more like christianity - there are quite literally countless different religious doctrines made at different times and that are accepted or rejected by various groups at various points of history. there isn’t anything quite like a central church, at least since the collapse of the Indian empire, so it’s more about which line of scholars and sages/saints you adhere to. hell, one of the major schools of Hinduism historically is literally atheist - following the Buddhist tradition, they deny the material world as real and seek truth in philosophy and spirituality. while this school isn’t strictly alive today, it forms much of the backbone of Hindu philosophy in the present.

    even not eating meat isn’t a universal. it’s a relatively common prohibition but one mainly kept by particular social classes (Vaishnavite brahmins in particular, though many others as well). for example, a lot of Shaivite families do eat meat - especially fish. it’s beef that’s totally unacceptable in pretty much all contexts and that’s because people drink cow’s milk. milk comes from mothers so to eat a cow is like eating your own mother.

    it’s very weird to me to consider any of these religious prohibitions, to be honest. the reasons are all framed philosophically and they’re accepted or rejected by various scholars contemporaneously with each other. and it misses weirder stuff like certain religious groups prohibiting garlic and onion because they make you more physical and lead you away from a path towards yoga (union with the divine soul of all things). but again, this is only done by very particular groups and at very particular times. my grandparents adhered to this and the rest of my family did not.

    I think a lot of what gets confused here is that Hinduism incorporates so many different belief systems - I’m not sure I’ve ever seen any other religion that absorbed quite so many, not by treating other religions as heresy and wiping them out (though that obviously happened too) but more often just because some sage decided to study the other belief system and came back and said “I tried this and I was able to achieve union by following their path - their beliefs are Hindu”.

    as a contemporary example, there are sects of Catholics in India that the Catholic church refuses to recognize because they’re convertees who invented their own fusion of Catholicism and Hinduism that has Jesus as a previously unrecognized avatar of Vishnu, or names Krishna to be an avatar of Jesus, while adding a bunch of saints because, like Mormons, they believe Jesus came to live among them and converted some saints during his travels. this kind of local incorporation and reinvention is utterly commonplace.

    (this is actually one of the more infuriating parts of the religious strife between Hindus and Muslims - Islam was decreed Hindu during the Mogul empire, just as Christianity was during the British empire. the British stoked the flames of religious war to serve their own ends - but the whole reason there are so many Muslim Indians is because the Hindu institutions welcomed conversions as entirely consistent with a path towards divine union.)



  • god he took me so many tries that watching someone attempt the fight made me realize I wore an extremely deep groove into my brain. my shoulder twitches every time you have to dodge two fucking years later.

    does he actually input read, though? I remember baiting him with spacing to consistently get free hits and then dying because I got greedy and went in for just one more with a large club that locks you into a swing for an eternity. if you run to the far side of the arena from him, he does the slow, heavily telegraphed flying attack eventually so you dodge under him, let him do a combo in the wrong direction with just enough space that he can’t do the reverse claw/tail swipe thing, watch for his shoulders to relax, immediately jump attack and dodge again as soon as you connect, and break for the opposite side of the arena to rinse and repeat. he always looks like he’s open to one more swing and he will get you if you fall for it.

    so I think what he does is entirely in relation to where you are relative to him? dunno though, I wouldn’t put it past them to cheat the difficulty. I’m really bad at reading tells and reacting fast enough so I had to come up with safe strats like that for every fight and just gave up on the game because fuck doing that much work to play a game.
