> spin 1/2 particle
> turn 360 degrees
OP your joke doesn't mean what you think it is.

>>15426847
Both of those "spins" are the exact same thing just rotated 180 degrees

>>15426856
i thought he was making a joke about the 720 degree full spinor rotation necessary for spin 1/2 particles to return to their original orientation. was he not?

>>15426890
the normal meme about "turn 360 degrees and walk away" is a joke because 360 degree is the same direction. that doesn't apply here.

>>15426896
so then that's exactly the point you autistic retard

>>15426877
Oh, well, gee, anon. I wonder what the reason for that could possibly be?! Could it be that rotating by 180 degrees reverses the positive and negative directions of the two axes perpendicular to the axes of rotation?? Good gosh, I wonder!

>>15426999
But that means there is no spin +1/2 or -1/2, they're spinning the exact same way

>>15427007
They have to be related by unitary transforms because of the way rotations work sweeaty

If they are like this their magnetic forces wont repel them out of orbit

I barely see why QM is a thing. It just overcomplicates things without any proven application

>my boyfriend better not be pondering his orbitals again

>>15427010
>because of the way rotations work sweeaty
They're rotating the same way though, nothing physically changes about them besides you changing the direction you view them from

Quantum mechanics is a scam

>>15427964
It's not a scam it just gets latched onto by morons to try and justify retarded psudomythological "philosophical" beliefs. At that scale nearly 100% of what happens is counter-intuitive coming from a classical perspective.

>>15427988
No, the "scientists" are the ones running the scam

>>15427988
lmao. Did you watch too much marvel quantumania,söybot?

>>15427488
That's how it should be sweaty. In exactly the same way that the only difference between something which is moving with a constant velocity and something at rest is a change in inertial reference frames.

>>15428223
>sweaty
this meme is dumb
its sweety
calling people sweety is more insulting and condescending
calling people sweaty assumes they just came back from a run with a wet shirt
stupid meme.
or is everyone literally too stupid to know how to spell sweety

>>15428231
idk i just like spelling it sweaty

>>15426953
he should've spaned 720 degrees

>>15428312
Acktshually even rotating by 360 degrees gives the same state up to a phase

If spinor representations have a continuous symmetry over 720 degrees then why is spin only binary?

>>15428223
>the same way that the only difference between something which is moving with a constant velocity and something at rest is a change in inertial reference frames
Wrong because you can treat the entire universe as a fixed reference frame and establish the velocity of an object based on it's change in position

>>15428790
Cringe and wrong and irrelevant and misses the point

>>15428454
Because SO(3) is compact which means that its unitary irreps are finite dimensional so the spin can only take finitely many values (not necessarily binary)

>>15428821
>no argument
Thank you for conceding retard

>>15428231
>>15428309
yah gotta agree sweety is better, change it up

>>15428863
I don't argue with schizos sweeaty

>>15428868
The best I can do is sweeaty. take it or leave it

>>15428882
>I don't argue with schizos
Well yeah, I imagine arguing with yourself must be pretty difficult with all the retardation that comes out of your mouth

>>15428882
i'm just reading it as sweaty tho, and with this context you've given it seems like you've been called retarded so many times you just don't care anymore so you just kinda roll with it.. you know?

>>15428890
>>15428893
>seething schizos
It looks like my superiority has resulted in some controversy

>>15428906
>still no arguments
Sorry, you lost sweatie

>>15428906
i've never cared about anons well being before but i hope you find a way to better spend your time.. you're trying to lash out on a japanese image board.. just hope you get healthy anon!

>>15426999
>>15427007
electrons do not spin.

>>15428929
Electrons are fucking gay

>>15426896
>>15426890
360 degrees is the same direction for a spin 1/2 particle too. The overall minus sign is unobservable.
