elegant: "the quality of being pleasingly ingenious and simple; neatness."

definitely less subjective than beautiful. and it's not arbitrary - i've alluded to an argument that can be made. i'm not going to spell it out because as usual no one on here is receptive anything that doesn't valorize stem.

Beauty: "a combination of qualities, such as shape, color, or form, that pleases the aesthetic senses, especially the sight."

So I cannot like the shape or form when I look at a proof or function? I cannot have my aesthetic senses pleased by looking at STEM field things?

i'm sorry but what is the shape or form of a proof? a function maybe - and calligraphy is certainly an art but what's wholly different from what the function encodes.

Proofs have structure, i.e., shape or form.

they have a logical structure (claim, lemma, lemma, proof, etc.). they do not have a shape in the sense that the person i responded to intends.
