What is entanglement? Itamar Pittowsky claimed that these results brought us right to the precipice of logical contradiction--but not over. Abner Shimoney described it as a piece of "experimental metaphysics." I'm a nobody, but I think entanglement is the most interesting thing ever discovered.

what are the graph connections indicating?

its hurting me right now!!

isn't 'vector' sort of unique for this? "group elements" don't have a special name either. or ring elements.

its probably cause physicists started off conceptualizing vector as a kind of property (thing what is an arrow) rather than as belonging to a structured set

we did figure this out

but, thank you 🥰

oops i meant to say associated to GL(nR) itself
uberwensch.bsky.social
the approach of many texts is to regard vector spaces as "associated to" a GL(n,R)-torsor by its action on frames. i.e. writing [1,2,3]_B where B is a basis and saying its equal to [1,0,7]_b for some other basis.

makes more sense to me personally to wedge the two vectors together first into a surface area element and then feed it to a dual-of-such-things but it all shakes out the same

when are two things equal? never. if they were equal, they wouldn't be two things. you're welcome.

it also points at the difficulty of equality - using Frege’s terminology, we have 1 and 0.999… denote the same real number; have the same reference, but have a different sense. Equality of real numbers is the _extensional_ equality of what they denote (e.g. Dedekind cuts).

the only downside (or maybe its upside) is that I don't think Everett (or other many-worlds scenarios) fits into things very nicely

since its in the form of an inconsistent triad you can even have them think about which premise they would prefer to drop

Bell experiments are a really nice place where you can sell someone on the weird quantum world with literally just the observed statistical frequencies, without using any formalism or saying "superposition", "interference", or "collapse"

Check in Marsden & Ratiu, at page 170 (PDF page 184)

It's the point-wise adjoint of the tangent lift. There's a proof that pullbacks by these preserve the canonical one-form.

I will think about it 🥰

Thank you for engaging with me so much on this

diffeomorphisms of the base have a "cotangent lift" which is a symplectomorphism. I'll find a reference for you in a sec.

If it harder in some sense to change the BC by way of the present, 1) what is this sense, and 2) isn't it part of what is to be explained? (Asymmetric influence on past and future?)
