seeing more math on the TL recently. i haven't mathposted in a long time but i'm still happy to field math questions from twitter peeps, just reply here or tag me or w/e. big meaty philosophical questions like "wtf are real numbers anyway" would be particularly fun for me rn

"theory" in math doesn't mean "stuff we think is true but we're not sure" it just means "stuff that's true." or like a bit more specifically, "X theory" is kinda like "the standard library of true facts about X, that you import to do stuff with X"
