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.

It's okay. I also had to look it up.

imagine this: sitting alone, rotting, just like you do in your bed, but you are also releasing gallons of CO2 into the atmosphere

I'm impressed you cover this in an intro course

can't buy tickets until i set up two-factor

Rochelle @uberwensch.bsky.social · Jul 24

i have to create an account with password if i wanna buy movie tickets. i already had to create an account with password to order pizza earlier. two-factor before i could choose toppings.

In fact, sometimes (generically, I would think), such as when an atom emits and then absorbs, systems have causal input from both ends!

Rochelle @uberwensch.bsky.social · 1d

Is a patchwork universe like this, with myriad interacting systems some of which have causal input handed down from their futures and others from their pasts, not an "impossibly hard sudoku puzzle"?

(It's not quite the same as concurrent equilibration/disequilibration, but it has a similar feel)

Gregor @coexact.bsky.social · 6d

I think it is extremely unsurprising. to construct a state in which one part of an interacting system equilibrates while another disequilibrates is some kind of impossibly hard sudoku puzzle. To find yourself in such a world might be reason to believe in God.

Is there somewhere I can see E&M formulated as a causal model?

It seems like the motivation for reading an un-emission as future-caused is due to the coincidence of converging radiation. But this is not really happening in photon absorption, is it?

Rochelle @uberwensch.bsky.social · 2d

so you're using a classical model to understand photon absorption and emission?

I don't think of emission as being much like classical concentric radiation (except emergently, for large photon number)

the state of the field prior to the shaking, and the intended curve x(t) for particle X?

Alright, let's hear about it!

(I think I first started thinking hard about the nature of time in E&M, when I learned about the advanced vs. retarded green's functions)

Ken Wharton @kenwharton.bsky.social · 5d

If you decide my argument works, start a new thread and ask me about the analogous case of microscopic classical E&M. The empirical evidence for causation in that case sometimes points in a very different direction!

and why does canada have a thanksgiving. was there a separate set of slightly earlier pilgrims or did canadians just eventually say "this turkey thing is baste"
