Dzięki fizyko, od teraz zamiast "szalik robiony na drutach" będę mówił "dwuwymiarowy mechaniczny programowalny metamateriał". Jestem sobie na konferencji (online), na której była m.in. sesja "Textiles and topology", której nie słuchałem, a chyba trochę szkoda, skoro w abstraktach można znaleźć takie fragmenty

" Knitted fabric is a 2D mechanical metamaterial constructed from loops of quasi-1D yarn, topologically entangled in 3D. "

"Knitted textiles are a type of 2D programmable material. Their emergent elastic behavior can be 'coded' in by changing the entanglement of yarn at the stitch level. Therefore, the natural formulation to describe and study complex knitted textiles is a language with a grammar. We propose such a framework, where the alphabet is composed of irreducible swatches -- knitable textile knots and links -- that can be concatenated leading to higher order or compound swatches. In this talk, first we define what are irreducible and reducible/compound swatches -- analogous to prime factorization of natural numbers. Then a set of operations acting on two or more swatches is described to define the syntax and grammatical structures of the proposed language of knitted textiles. Using this approach, we then quantify an upper bound on the number of words of fixed length in the vocabulary of the language corresponding to a knitting protocol capable of generating a finite alphabet"

@varelse Przypomina mi to teorię węzłów, którą miałem kiedyś wykładaną przez jednego faceta :D Pytanie z sali "a jakie to ma zastosowanie?" radosna odpowiedź wykładowcy: "Żadne! To czysta nauka!"
