frobunnius @catnaroek (possibly a bad idea): we should use words from lapine: watershipdown.fandom.com/wiki/Lapine to talk about Gal(Qbar/Q)

TJ Hitchman @catnaroek @katemath Desmos I like using sagecell.sagemath.org since it's an easy free way to access several open-source tools (in contrast with Mathematica). But while Desmos/Geogebra are closed-source, they are much nicer for general audiences to use. I'd love to see that functionality come to FOSS.

@HigherGeometer @catnaroek Ok, but did they have an explicit construction of an object satisfying their tricategorical universal property? 😝

@HigherGeometer @catnaroek Can you give an example in which you know something characterised by a universal property actually exists, without having given a construction?

@catnaroek and we're back syzygay Sure, that makes sense. But discovering that Santa isn’t real also hurt me back then. You just destroyed a part of my math-childhood!

@catnaroek justinhj Jessica Joy Kerr Inactive; Bluesky is @hillelwayne(dot)com If you're going to tell lies to children you should remember that some are A students with nearly eidetic memories and get really stressed when they find out their moral source of truth gave them lies in the name of expediency.

At least give them footnotes and wave your hands.

@catnaroek @mathemensch why other hand libre office does this too whilst using file formats actually usable by all people and whilst not spying on you.

@catnaroek johncarlosbaez julesh I would argue that the notion of oo-category (whatever definition you use) is not purely algebraic. For example, the (oo,1)-category of (oo,0)-categories is the oo-category of spaces (so for example, it contains a lot of information about smooth structures on spheres).

Number less than 2^2^2^64 @catnaroek Anton Hilado Yes in some parts of arithmetic geometry/number theory, and for PhD students, this is almost impossible, and almost certainly counterproductive.

@catnaroek Daniel Litt If you are not in a hurry, there is Milne's recent book on the topic. It develops the theory over a general field and is rather scheme-heavy.

@catnaroek QC hmm i've never had that concern. almost every tab i have (often thousands) will stay the same if closed and opened again (for example, links to individual tweets). the problem is how to find those tabs again when i want them in the future, or whether they will be lost forever.

@catnaroek Shriram Krishnamurthi 🟤 🏴‍☠️ 👨🏽‍🏫 🚴‍♂️ 🏏 A Spanish person explained to me that 'ser'/'estar' is easy to understand with the permanence vs. impermanence angle. I pulled out lots of exceptions: 'estar muerto,' 'la fiesta será mañana,' 'son las 8,' etc. For native speakers it comes naturally but it's actually complicated.
