Hi, I will be applying to graduate school about a year from now and am planning on studying experimental/theoretical quantum information (and/or quantum optics). Since quantum information is a relatively new field I am having a hard time finding advice on how to prepare. I have taken all...

Thank you both for your responses. I now understand.

I have two questions: i) Does a distinct equivalence relation on a set produce only one possible partition of that set? ii) Can multiple (distinct) equivalence relations on a set produce the same partition of that set? In other words, given a set S and two distinct equivalence relations ~...

I am an undergraduate physics major aspiring to study theoretical physics in graduate school. I was wondering if it is better to double major in math and physics, at the expense of taking less physics classes and more rigorous proof based math, or minor in math and take the two semester...

Perhaps the Fresnel equations provide the necessary theoretical explanation?

If I send a pulse down a string with mass (m1), consider what happens at a point where the mass of the string becomes (m2): i) If m1 > m2, the wave is reflected with the same phase as the incident wave. ii) If m1 < m2, the wave is reflected 180 degrees out of phase with the incident wave...

My reasoning for getting a MSc is the following: I will most likely have a mediocre GPA (3.3 - 3.5) by the time I get my BS in Math and Physics. I anticipate a good physics GRE score, but I only have EXPERIMENTAL research at this point, and I want to study theoretical. Given the highly...

Is there any advantage in getting a masters of science (say for theoretical physics) before getting your PHD? I was thinking it might be easier to be admitted to a better PHD program if you obtain a masters degree at a different school first, as oppose to just applying to a PHD program right out...

Thanks for the post. Does anyone else have anything to add?

I have read the numerous threads discussing experimental vs. theoretical physics on this forum. I am leaning toward pursuing theoretical physics in and after graduate school despite the numerous caveats regarding job prospects. I realize that one need not make a decision between theoretical and...

Thanks for the advice. I haven't had much experience with ODEs, so I think the best way to learn problem-solving techniques involving ODEs might be to practice problems over and over again until the appropriate methods involved in obtaining solutions becomes more obvious.

Sorry, that was a lot simpler than I thought. Thanks for your help!

The problem asks me to solve the following ordinary differential equation for y(x): y'(x) = cos[y(x)-x] I have tried multiple methods to solve this equation, including expressing the O.D.E. in its complex form. I also tried expanding the O.D.E. using the angle difference identity...
