Homework Statement I'm checking to see if the momentum operator is Hermitian. Griffiths has the solution worked out, I'm just not following the integration by parts. Homework Equations int(u dv) = uv - int(v du) The Attempt at a Solution I've attached an image of my work. It seems there...

Throughout my undergrad career I relied on help from others, the internet, and the teachers allowing us to use equation sheets during examinations. I received all A's in my upper level physics classes, and B's in the introduction classes (which I used Yahoo answers for almost every homework...

I don't think so. Should I just rewrite it as: dt = -(gsin θ -(c/m)v^2)^-1 dv and integrate?

Homework Statement A puck of mass m is kicked up an incline (angle θ) with initial speed vo. Friction is not present, but air resistance has a magnitude of f(v) = cv2. Solve Newtons second law for the pucks velocity as a function of t on the upward journey. How long does the journey last...

I'm just reaching out to fellow graduate students who have already been through this. I'm about one month out from starting classes for physics phD program. Here are my concerns/questions: There is a preliminary exam; if students do not reach a certain percentage they will recommend (and may...

University Y's deadline was the same as X's... I guess they extended it to people on the waitlist?

I just wasn't sure if there were any legal ramifications or if any thing PHYSICALLY prevents me from doing this. I know that the applications for these institutions are all linked from a common provider/site/host (not sure what you would call it).

Sorry for the confusion. The problem is they are making the offer (possible offer) tomorrow, on the 16th. Not that I want to be inconsiderate, but if the school is a better match, then I would find it hard to turn down that offer.

I applied to universities X and Y. University X got back to me quickly and I visited and was relatively pleased with my visit. Recently I accepted this offer at X University, since University Y said I was wait listed. University Y says that they will have a couple of positions open, and they...

If you have trouble with a concept try using YouTube. Seriously.

This is the feedback I keep getting. I will probably take it back, but it says on the departments webpage that graduate students will spend a good deal of time teaching so I wanted to include ho my experience would help. P.S. It it quite clear I need to change 'women', I meant holding...

Just as another example of extra curricula.. perhaps relationships is a better word.

Here is my second draft, a decent improve from first. I really do not like my first and last paragraphs, they need some big-time help. Thanks. Also, I think it's questionable putting in the italicized sentence. Let me know what you think. Earning a PhD in physics would allow me to continue...

B) Writing the Statement of Purpose: Part 1: Introduction Part 2: Summarize what you did as an undergraduate a) Research you conducted. Indicate with whom, the title of the project, what your responsibilities were, and the outcome. Write technically, or in the style of your discipline...
