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

you can sort of think of the real numbers as supplying “as much precision as you could possibly need.” in practical applications you only need a certain amount of precision - 5 decimal places, 10 decimal places, w/e - so you never need to engage with the full weirdness
