<NomalRaptor> Anyway, today in struggling with basic things: https://photos.app.goo.gl/DQtuz9UaGgjsrdpp8
<NomalRaptor> I'm missing something obvious because I can't see how to distinguish between Lx and Ly
<NomalRaptor> L and Lz give you Lx^2 + Ly^2, but separating them?
<egg> bofh: ^
<egg> ;choose fetch a hydrogen atom from the shelf|find one online
<kmath> egg: fetch a hydrogen atom from the shelf
<NomalRaptor> One of those bosonic hydrogen atoms.
* NomalRaptor pokes at Griffith's
<egg> "the gross structure of hydrogen", J.P. Home, December 12, 2011
<NomalRaptor> … breaking the degeneracy is going to involve ladder operators, isn't it?
<egg> also turning on the lights so i can read those lecture notes
<egg> about gross hydrogen
* NomalRaptor hands egg 144 hydrogen atoms
<egg> NomalRaptor: tbh i'm shit at QM and it's been 7 years since i took that course so it will take me a bit
<egg> try to poke the actual physicist
<egg> (problem: this requires a flyswatter)
<egg> BOFH
* NomalRaptor empties a square box containing 144 hydrogen atoms on bofh
<egg> NomalRaptor: wait, I also have actual QM lecture notes (in german though)
<egg> that's from 2013/2014
<egg> bofh
<egg> gah how did i forget everything about the hydrogen atom, also why is bofh always unreachable
<bofh> 00:16:56 <@NomalRaptor> I'm missing something obvious because I can't see how to distinguish between Lx and Ly
<bofh> I mean those two should have the same eigenfunctions for an s orbital b/c symmetry
<bofh> anyway let me check the link
<bofh> OH
<egg> bofh: isn't this a p orbital?
<bofh> egg: yeah it is
<NomalRaptor> asddfsffasaf
<bofh> NomalRaptor: split each state up into tensor products of simple states, I'd say.
<egg> bofh: what do you mean
<bofh> one moment, IRL stuff.
<egg> also shouldn't we summon raising and lowering operators somehow
<NomalRaptor> I mean, Lx^2 + Ly^2 = L+ * L-, but I'm unsure that helps.
<egg> uuuh
<egg> isn't that precisely not the case?
<NomalRaptor> … oh
<NomalRaptor> L+ + L- = Lx
<egg> NomalRaptor: L+ L- = (Lx + i Ly) (Lx - i Ly) = Lx^2 + Ly^2 + i Ly Lx - Lx i Ly = Lx^2 + Ly^2 - i (Lx Ly - Ly Lx) = Lx^2 + Ly^2 - i [Lx, Ly] = Lx^2 + Ly^2 - i [Lx, Ly]
<egg> [Lx, Ly] is not 0
<egg> it's i hbar Lz I think
<NomalRaptor> And I can find L+|ψ> because I know n
<NomalRaptor> Yeah, it is iħLz
<egg> life doesn't commute
<egg> to quote trubowitz
<NomalRaptor> No transit, only cars
<NomalRaptor> At least orthogonality kills crossterms.
<egg> yay
<egg> NomalRaptor: yeah, L+ and L- are nicer to work with
<tawny> I've only just now realized your name is "nomal raptor" and not "normal raptor"
<egg> yes, nomal
<egg> like the goblin
<NomalRaptor> See the gist in the /topic for details
<egg> NomalRaptor: does it work
<NomalRaptor> seems to
<egg> yay
<egg> NomalRaptor: I'd say ask bofh to check the results but that would take months >_>
<NomalRaptor> lolsob
<egg> moths even
<egg> I could try checking the results, but i'm not sure i remember anything about the hydrogenoid atom
* NomalRaptor still needs to stab myself^W^Wfigure out C++11 enough to poke at kozai stuff
<egg> well, eggsams should take precedence
<egg> at some point you can go to ANBO or something and I can feed you some Principia
<egg> or dishes that use steam as a structural component, whichever one sounds more like food
<NomalRaptor> structural steam
<NomalRaptor> I have questions
<whitequark> um
<egg> whitequark: look, https://twitter.com/gcouprie/status/1081553458472325120 is only scratching the surface
<kmath> <gcouprie> how to find out if something is edible, the French way: ⏎ 1. you can probably eat it ⏎ 2. if you can’t, drown it in but… https://t.co/JljcXOVGc1
<whitequark> oh

<B787_300> but mmmmmmmmmmmmm drowned in butter and garlic
<kmath> <MiodVallat> @gcouprie Rocks aren't actually that bad. You need to slice them in small enough chunks.
<B787_300> egg: got to get your minerals somehow right

<egg> NomalRaptor: do you have other QM questions
<egg> why am i not zzz
<NomalRaptor> egg: Have you tried applying the zzz operator to yourself?
<NomalRaptor> (Uh, not at the moment)
<egg> hmm
egg is now known as egg|zzz|egg
