I love working with Tarski’s world when doing logic puzzles! Idk, I just like writing sentences in FOL and trying to prove them true.

fiabe

Romanzo d'avventure e fiaba sono due stili diversi, e attivano in misura diseguale due facoltà diverse, quella della logica e quella dell'immaginazione. Ad Alfred Tarski (1901-1983), che in filosofia era un nominalista materialista, era spesso richiesto di spiegare la presunta contraddizione tra le sue idee e matematica che coltivava, soprattutto teoria degli insiemi, cioè una teoria di cose che egli non credeva esistessero; Tarski rispondeva così: "Io credo che ci sia un valore anche nelle fiabe, e nello studio delle fiabe." da Rapidità, in G. Lolli, Discorso sulla matematica. Una rilettura delle Lezioni americane di Calvino

People on this site will put together polls like "The Banach-Tarski Paradox versus Camembert Cheese", then act like the results prove that they're surrounded by idiots.

on Tarski's T-sentences

Tarski's IF/IFF (sufficient/necessary) distinction regarding sentence truth is more than anything about the contrast between the multiplicity of falsity conditions and the uniqueness of truth conditions. So,

“snow is white” is true IFF snow is white (necessary)

But the counterpart,

“snow is white” is true IF snow is white (sufficient),

leaves open the possibility that other facts, if realized, could also make the sentence true -- i.e., perhaps "snow is white" could also be true if snow were purple, or if crabs walked sideways. But we know ALL such correspondences to be linguistically impossible.

In other words, sentences have only ONE way (one necessary/IFF way) of being TRUE.

But they have MANY or (almost) INFINITE ways of being FALSE. As a student reminded me, they have an infinite number of ways minus one!

hey uh sorry but your boyfriend took the axiom of choice and we cut him up into five pieces and reassembled them. he's fine there's just two of him now.

When a mommy skeleton and a daddy skeleton love each other very much they run at each other full-speed and crash into a huge pile of bones and then their disembodied arms start putting themselves back together but they do it wrong so now they've got their skulls on backwards and arms where their legs should be and ribs all over the place and after a few failed attempts they conglomerate into one big two-headed eight-limbed double-skeleton but eventually they get it right and reform back into their separate selves but somehow in the middle of it all enough bones got dropped and misplaced that they have enough spare parts to make a baby skeleton!

Wanna know an anagram of Banach-Tarski?

Banach-TarskiBanach-Tarski

#math #mathblr #pun #get it? because an anagram takes the thing breaks it apart in (countable many) smaller objects and rearranges them #and by banach-tarski we can get the same set twice #calculus #banach #banch tarski

i will always associate the banach-tarski paradox with bdsm and gay sex, for reasons i will not explain <3

#sorry. i just felt like i needed to share this random fact. #why have been i getting banach-tarski jumpscared so much lately

Si la mecánica cuántica te volvía loco, espera a ver lo que dicen las matemáticas. Echa un vistazo a la paradoja de Banach–Tarski, verás que curioso.

¿Puede una esfera descomponerse en un número finito de conjuntos de puntos y volver a montarla en 2 esferas idénticas a la original?

Imagina que lo hacemos con billetes...

Fuck yeah managed to find a super cool paper again

Banach–Tarski paradox

The surface area of my cat pica is probably less that a square foot... and yet, in a real-world illustration of the Banach–Tarski paradox in action she can cover 100s of square feet of carpet, clothes and furniture with cat hair!

Who said pure mathematics is useless?

My mom offered me a sip of her fountain coke the other day, going years without drinking soda meant that it was kind of nice at first but ultimately just too sweet and syrupy.
