OP's image is an ace student who decided to bail out of acceptance to organic-neuro-cat-girl-robot-scientist school to become a bar tender at a bar so shitty it has a serial code instead of a name. She did this because she didn't want to be a lab drone. To be happy, you need to have your own values and prioritize them over fitting a mold parroted to you by family, friends, or society.

More practical advice: You didn't completely forget anything. You can rapidly relearn all the core material.

Let's start here: do you know the meaning of the words you're using?

I don't know why that shit gets spammed here on /sci/ the plot make absolutely no sense, it's all pure trashy pseudo-science and full of paradoxes, the creators got lost in their own story and theory. The ending is also terrible, especially the extremely cliche last sentence 'hurr durr no one can predict time, enjoy your best'. Really, sci? I expected more from you.

>discretization of spacetime
You do know that has nothing to do with the Hilbert space of states in QM being finite right? Regardless whether if you're on a lattice or not you cannot use finite-dimensional Hilbert spaces as a rep space of the Heisenberg algebra, end of story.

Just stop.

Can you please not use the n-word? I find it very racist and disgusting.

Anyways, think about how [math]|{\bf x}\langle[/math] is related to [math]|\pm \hat{\bf z}\rangle[/math]. The z-component tells you the handedness of the photon.
Alternatively if you're in 4D spacetime [math]M[/math], the [math]spinor[/math] bundle [math]S\rightarrow M[/math] allows you to define the unitary, idempotent chirality operator [math]\gamma_5 = i \prod_{\mu=0}^3 \gamma_\mu[/math]. So you just need to write linearly polarized states in terms of states in the eigensectors of [math]\gamma[/math].
Hope this is helpful.

>cross product on n-dim vectors
Goddammit.
Though pointing out the Poyntin vector is correct in the sense that light has two components of polarization orthogonal to [math]{\bf S}[/math].

Are you fucking serious?

Assuming anything that is not proven (except axioms lol) cannot yield a proof. Any mathematician thinking otherwise is an idiot.

Shipfags should fuck off of /jp/, it's a touhou board.

What the fuck is wrong with you people?
