I'd like to add that I'm speculating. I'm in physics lol.

I think I was getting at the origin of grammar, as communication becomes more complex rules are required so people don't get lost in translation. I think these rules naturally arose from self-correction. Kind of like evolution.

No problem, I recommend you look into rectangular/square wells to refine your understanding.

I'm assuming we started off with grunts and stuff just like other animals and we just kind of built more complicated sounds from there. Since different societies were isolated from each to different extents other languages developed. I wouldn't be surprised is latin and Greek got spread through...

Interesting, not sure if you will get important results but it would be a great learning experience. I suggest reading up on quantum dots as photon emitters, you can couple phonon modes in the crystal to the dot to cause excitations and emission. It seems complicated and wordy but I think...

Yep, as long as they are referring to E3 and not the third excited state in the problem,(E1 is the ground state the way you asked the question). And for your interest you are dealing with a symmetric box so the energy levels are degenerate. Meaning you could take 2,2,1 1,2,2 or 2,1,2. E2 would...

Find the maximum value of the function on the interval and multiply that by the interval length, tat is the maximum possible value for the integral (the upper bound). Try that and let us know how it goes.

Bear with me (Two part question), In the ideal case, an electron in a lattice under the influece of a static force will undergo bloch oscillations. A simple hamiltonian for this system would be: H=H° +Fx and V(x+d)=V(x) If I used the kronig-Penney Model would I be able to derive...

While studying the brillouin zone I came across the dispersion relation and the group velocity. The group velocity is given by v=dω/dκ, I understand this in the sense of beats where it is Δω/Δκ and I understand that the group velocity is the propagation speed of the envelope function. However...
