I'm sorry for the rapid fire posting, but I gotta vent on this.

Grad school is teaching me something valuable: hard stuff is usually incredibly easy stuff asked poorly. I just figured out why the average energy lost between a first and second collision to ions by an electron in a metal in thermal equilibrium separated by time t is (eEt)^2/2m.

Because

I think I know why school is hard for me. I expect tricky sounding questions to be tricky. So I work

PS: How to you solve for the total energy of a three electron infinite potential well using quantum mechanics? SOLVE IT USING CLASSICAL MECHANICS AND PUT HATS ON VARIABLES! That's right, three sets of 1/2mv^2. Substitute, and solve for the eigenvalues - I mean - invent equations you know will work. Seriously.

**E equals one half freaking m v squared**(where earlier we have defined v average to be -eEt/m, buried in a paragraph in the text; jerks). OMG high school physics. Ticks me off because they could come right out and say it, but no. They'll explain it the way that allows for such a freaking stupid question to be asked.I think I know why school is hard for me.

*really*hard trying to figure it out, and typically give up out of frustration. I'm done with that, and I think I'm done overkilling these stupid things. I think I figured out how to beat grad school - I'm onto their dumb little games.PS: How to you solve for the total energy of a three electron infinite potential well using quantum mechanics?
