I'd argue it's unfixable for low income workers. Excessive sugar in all the cheap food is a trap they can't avoid. They don't have money to buy better food and don't have time to shop and cook for themselves. That&#

My understanding of QM is very naive, but Schrodinger equation seems really simple to me. I could probably even explain it to a 5 year old. I'd show a few pictures of standing waves on a drum surface: the first two energy levels create

Is the accurate model that complex, though? An electron is a standing wave: one could show the first two standing waves on a drum and say these are the lowest two electron energy levels. Higher levels create more sophisticated waves, and no

I've seen a clever way to derive QM out of GR equations by making a single assumption: ds2 exp(C exp(-iwt)) = c2*dt2 - dx2 - dy2 - dz2. This extra exp() factor modulates the ds2 slightly, and when mixed with GR equations, it makes the

What if something else chosen as an initial condition, like a sphere or some random shape? Would it converge to something meaningful if we apply the time-dependent SE with a meaningful field potential?

Would it really just jump into another shape? I don't understand QM much, but the Schrodinger equation looks like a typical heat equation (with some complex-number trickery) and thus in general should evolve smoothly. There should be a

Is there a way to make these shapes evolve with time?
