that episode of voyager where she let down her hair really did something for me as a kid

QC @qchu.bsky.social · 07/05/2023

like you can take a look at the wacky stuff here, it's not hard to e.g. describe ordinals so large ZFC can't construct them, or any other particular computable list of axioms for set theory! en.wikipedia.org/wiki/Large_countab…

*how weird definite-but-not-surveyable collections are like the collection of countable ordinals is truly insanely large, almost all of them are impossible to describe in any fixed ordinal notation, e.g. almost all of them are uncomputable. it's extremely different in character from N

QC @qchu.bsky.social · 07/05/2023

i haven't thought through this carefully but yeah, i think in this framework aleph_1, or more precisely omega_1 thought of as the collection of all countable ordinals, is definite but not surveyable. in other papers i think he does a good job emphasizing how weird surveyable collections are

here's a reference to it from 1983 so it's been around for A While www.nytimes.com/1983/04/28/business…

QC @qchu.bsky.social · 06/05/2023

every picture or video of an animal is pretty much universally good, like it's really hard to go wrong with those. the fact that the same isn't true of humans points at some things that i think are very sad

QC @qchu.bsky.social · 06/05/2023

the version i heard as a kid was about russian to english and it ended up "the vodka is strong but the meat is rotten," this was a strong meme back in the day

QC @qchu.bsky.social · 06/05/2023

QC @qchu.bsky.social · 06/05/2023

QC @qchu.bsky.social · 06/05/2023

yes, for sure, didn't mean to imply it wasn't important. bluesky's gonna live or die on moderation. but also if moderation is the *only* serious discussion on here that's sort of not what we came for either right?

QC @qchu.bsky.social · 06/05/2023

i love stories like this that were only possible during a very specific moment in internet history. have a soft spot for sites that were extremely popular for a few years and then totally died

QC @qchu.bsky.social · 06/05/2023

hmm as far as my personal favorites the princeton companion to mathematics is way up there for raw density of information. i used to read this in the bathroom in college www.amazon.com/Princeton-Companion-…

the worst curse i can imagine inflicting on someone is deluding them about what love is, waiting for them to fall in what they think is love, get married, raise a family, and then fifteen years later cursing them to actually fall in love for the first time with someone else

QC @qchu.bsky.social · 05/05/2023

whoa deep

QC @qchu.bsky.social · 05/05/2023

yeah seattle's really not the place for you. the seattle freeze basically gives everyone very mild parkinson's, people literally move less and more slowly compared to other places

QC @qchu.bsky.social · 05/05/2023

actually if you reread his work with this in mind some interesting stuff sticks out. there are very few women, there's basically no sex, there is this interesting theme in a few stories of reproduction without sex... there's a whole book about this: www.jstor.org/stable/j.ctvhn09p9

QC @qchu.bsky.social · 05/05/2023
