Please say something to me before following me! I'll have to carefully scrutinise your follow request if we haven't exchanged any words, but I'll probably approve it right away if you at least say hi. It's more work for me if you request a follow without any previous interaction.
I'm married; no flirting please.
Hm, @npub1g8n0...xq74 there seems to be some sort of bug setting CWs? They show up as the body of the toot instead, with no CW.
Award winner indeed.
I still recall the undersea award ceremony with great fondness.
I live phoneless, AMA.
It's kind of fun, in terms of mathematical philosophy and history, how the symbol ∈ comes from Latin "est", meaning, "is", as in "x is an integer" or 𝑥 ∈ ℤ, but nowadays we interpret that as "x is in the set of integers".
It kind of goes back to the origin of set theory when we thought that everything could be define with comprehension before Russell found contradictions like "set of sets that don't contain themselves" (I think "set of all sets" was due to Frege?")
Anyway, back then being in a set was assumed to be the same as satisfying a predicate and they thought you would specify a predicate without reference to an enclosing set.
So "Billy is a punk", or 𝐵𝑖𝑙𝑙𝑦 ∈ Punk was seen as equivalent. There was no need at the time to distinguish predicates from membership because there was some implied universe of all sets where each predicate would cut out a subset from.
Only when we realised that predicates had to be in reference to an enclosing set in order to avoid contradictions, only then did we change the meaning of the ∈ symbol from "is" to "belongs to the set".
The only Sci-Fi story I know that has predicted our current AI present.

Help, I'm despairing over how AI is gonna kill civilisation but not in any scenario that sci-fi prepared us for.
Hey, French speakers, if I said "j'ai une collection de cheval" or "j'ai plusieurs cheval" does that sound acceptable to you?
(I am not interested in whether you were taught in school if it was correct or not. I want to know if YOU think it sounds fine or if you would immediately be like "hein?" if you *heard* someone say that.)

Oh are we doing math jokes today?
I wonder if I'm the only one who reads math this way.
I'll take some text (a book, a paper, whatever) and I'll start reading it from the beginning, very carefully, working out the details as I go along. Then at some point, I get tired but I wonder what's going to come later, so I start flipping around back and forth to just get the "vibe" of the thing or to see what the grandiose conclusions will be, but without really working anything out.
It's like my attention span runs out but my curiosity doesn't.
Is this a common experience?
