  • What I see from this is “don’t try to ‘help’ the poor by creating programs that give them jobs [public workshops]. Help them unconditionally”

    Basically, fdr’s new deal policies were still a capitalist approach that could have been replaced more elegantly with free food and housing.


  • It’s not really communication. They ‘know’ because they become part of the same wave function. The wave function of the system is

    |psi1 psi2> ± |psi2 psi1>

    Note that if the ± is a plus, then exchanging psi1 and psi2 yields the exact same equation. If it’s a minus, you get a negative sign out front. Electron systems have a negative sign because of the spin statistics theorem (I don’t understand that part, so you can look it up if you want—it involves field theory iirc) Now, if electrons are exactly the same (indistinguishable), then exchanging them will yield the exact same wave function, leading to

    |psi1 psi2> - |psi2 psi1> = |psi2 psi1> - |psi1 psi2>

    The only solution here is |psi1 psi2> - |psi2 psi1> = 0

    But recall that |psi1 psi2> - |psi2 psi1> describes the system as a whole. So this system is prohibited by quantum mechanics, and there’s no way for two electrons to have indistinguishable states (be in the same place at the same time).


  • This is a forum. If you don’t get the joke, you can ask and have it explained to you. Most memes are some form of in-joke regardless, so you often have to do a bit of learning the first time.

    What was off about your first comment was recognizing it for what it was before proceeding to miss the joke entirely.

    What was off about your replies was trying to compare it to the Scottish coat of arms; if you know the Scottish coa, you probably wouldn’t associate it with piss yellow and white. If you don’t know it, you wouldn’t mix them up anyway.









  • It (along with Stokes’ theorem (they’re actually the same theorem in different dimensions)) helps yield Maxwell’s equations; specifically, if you want to change the flux of the electric field through a surface (right hand side), you need to change the amount of charge it contains (the source of the divergence on the left hand side). In other words, if you have the same charge contained by a surface, it will have the same flux going through it, which means you can change the surface however you wish and the math will still be the same. Physicists use this to reduce some complex problems into problems on a sphere or a box—objects with nice, easily calculable symmetries.





  • It’s (shorthand)[teeline.online]. It says “prc(t)ml” with the p being in the obvious spot (though it should be just a downward line), the r is the diagonal line after it, the c is the little curl, the t should be more pronounced, but it should be a horizontal line slightly above the rest, the m is a concave-down swoosh, and the l is the final curl. No vowels b/c they’re largely redundant.
