I worked or a gamma-ray group this summer on a program for telescope alignment. There wasn't much physics, but I learned a lot of computer programming, and my professor says that he will write a very good letter for me. I have half of the summer open during which I plan to study for the GRE...

OOPS! I forgot the most important part of the last post. I WANT to take the grad courses, but is it a good idea or are there better ideas?

I'm wondering if its not the greatest use of my time to start taking grad courses as an undergrad. I will presumably take them in grad school anyway, so should I consider something different?

I don't think that I have shied away from upper-level courses. I have taken Mechanics (only one semester is offered), both semesters of E&M, the highest level of undergrad QM, a class in particle physics, the GR, and a class called physics of the brain. Next year, I will definitely be taking...

Thanks for the post! It was a nice surprise, since I thought I had resolved this thread. I completed the assignment, but I will certainly look for the paper.

I'm an undergraduate who will be going on to graduate school in physics. I only have two physics classes remaining after this semester, but I have a full year before graduation. Any recommendations for classes to take/things to do in the meantime. I've got a couple ideas myself. What do you...

I think the issue here is that I just need to face up to the messy algebra. Thanks.

well, you're right about the electron problem. 0.4 is the correct answer. I'd use the practice exam to help you know WHAT to study but I wouldn't trust it for the answers.

That's not exactly true. I'm taking an undergraduate course it particle theory. It seems to me like the OP is not yet in college. If you are a high schooler and interested in physics but worried about math, I have a few suggestions. First: Practice the basic math over and over until you...

Also, by "second problem" do you mean the one about the earth? If so the Earth is (almost) a solid sphere which has a different moment of inertia than a disc.

Think about conservation of total energy of the entire system. That's always a winner. so E(atom initial) + E(electron initial) = E(atom final) + E(electron final) You know three of these. You are given the first two and you are correct as to the final state of the atom. Just solve for the...

The distance traveled by the wave is not 735 meters. That is the distance to the cliff. From this, find how far the wave travels during the four seconds that it takes for the shout to return to the hiker.

Homework Statement This question is very simple, but it is driving me mad. Show that the Schwarzschild metric in Kruskal coordinates takes the form ds2 = (32M3/r)e-r/2M(-dv2+du2) +r2(d(theta)2 + sin2(theta)*d(phi)2)Homework Equations The equations are just those defining the Kruskal...
