Thank you. This is helpful advice as always.

I am a first-year PhD student who worked with a professor over the summer. I get along very well with her, and I would be happy to work with her if I was certain that my interests aligned with hers. She is a very popular advisor and has a lot of students wanting to work with her, so she gave me...

I am by no means qualified to give advice on how to look for grad schools (seeing how I'm basically in the same situation), but this website seemed to me to give pretty helpful advice: http://www.physics.unh.edu/undergraduate/advice-physics-majors-grad I also recently found this from the APS...

Thanks for the responses. I shame that more than 3-4 grad courses would probably be difficult to do, but I suppose that is expected. I guess I'll have to choose those classes wisely (assuming I'm allowed to take them in whatever school I end up in). Funny! Just knowing myself, I wouldn't be...

I'm an undergraduate who finished up my junior year this past Spring. I've been looking around at grad schools for physics. However, I find myself about as unwilling to study physics in grad school and leave pure math behind, as I am unwilling to do things the other way around. Math so far has...

Gravitomagnetism is cool. I'm at FAU (just finished junior undergrad year). From what I recall, one of my fellow students asked about the physics PhD program during one of our classes, and apparently, there aren't enough faculty to run one. The reason they are heavily into theoretical physics...

Interesting, thank you. I'll have to take a look into that.

Is there a field of "Mathematical Astrophysics"? Just was wondering (for graduate school purposes), is there a field that does what mathematical physics does but for astrophysics? (e.g., perhaps simplifying or re-expressing the mathematics used in some subdiscipline of astrophysics?) Or perhaps...

Thanks for the replies! That's a lot of good stuff to take into account.

Thanks everyone! That's already a lot of good and helpful advice to ponder over and put into use. I'll definitely have to see whether the job will let me work on a weekend...well, if I find that it's possible for me to study after working. As far as I understand, the shifts are 4 hours at a...

Hello, This semester I will be taking quantum, statistical, and classical mechanics, along with a mathematical analysis class and one other (non-math/science) course. They come to a total of 17 credit hours. The quantum and statistical classes are meant to be the standard sort of first courses...

Okay, I get it now. That illustration was very helpful. Thank you very much!

Ohhh, I see. Doing that, I get -T = Ma_cart for the cart alone, and if I use the two earlier equations with a2 = a1 - a_cart, I get the book answer. At last! The only problem is that I still don't quite understand why a2 = a1 - a_cart. I can see that in the equation m2g - T = m2a2, a2 is a...

Ohhhhhhh! I see it now! Let w = x0 - x = the distance from the glider to the edge, where x0 is the original distance of the glider from the edge. w = (z2 - h02)1/2, so dw/dt = z(z2 - h02)-1/2(dz/dt) = u(dz/dt). Since h = h0 + (z0 - z), where z0 is the original value of z, dh/dt = -dz/dt...

x = (z2 - h02)1/2 x/z = cos(theta) --> x = zcos(theta) = z/u (z2 - h02)1/2 = z/u --> u = z(z2 - h02)-1/2 That gives me u, but I still don't see how to get the relationship vx = uvy from this information. =( The closest I can get is the reverse relationship, though with lots of other...
