comment Problem with (grad school) physics education?
It seems to me what you describe is true of almost all grad students, in theory or experiment. Thesis projects are so focused on one thing, all you need to know for your research is the background of that one thing. I think the broad(ish) classroom experience is not there to teach you how to do your thesis research; it is to teach you how to be a successful researcher after you complete your thesis research. The goal is, eventually, for you as a mature researcher to make connections between disparate ideas, which you can't do if you haven't seen them before.

comment The far $\vec{\mathrm{E}}(\vec{\mathrm{r}},t)$ field of an arbitrary antenna given an arbitrary input current $I(t)$
I think this is question more appropriate for Electrical Engineering Stack Exchange.

comment Sign Paradox in Berry's Phase
I suspect there is a mistake in your Taylor expansion, but I wasn't able to track it down. It strikes me as odd that you start with only $\tau$ and $\Delta\tau$ but take a $t$ derivative.

comment General Physics II Practice Question
That looks like an equation for the force on a point charge due to another point charge. I bet you have learned some equation about forces on wires.

What equations have you learned in class about forces on current-carrying wires?

comment Are length contraction and time dilation physical?
Lots of info out there if you just google for it. For instance, these Wiki pages: Length Contraction#Experimental Verification, Time Dilation#Experimental Confirmation, Tests of Special Relativity.

comment Matrix operations on Quantum States in a composite quantum system
What operation are you trying to do with $\hat{S}_z \otimes \hat{J}_z$? You could, potentially, do the simple projection you're talking about with $\hat{S}_z \otimes \mathbf{1}_{3x3}$ and $\mathbf{1}_{2x2} \otimes \hat{J}_z$, but in general you're going to need to deal with adding the angular momenta of the states.

answered Does Newton's first law state something substantive, or is it merely describing a convention?
