I agree. I graduated with 25k of debt, and that was just because I did volunteer research and didnt work much the last two years.

Hi all, I wonder what some of you might know about this field. It seems to be quite interdisciplinary and also in its infancy. I wonder what some of you may think about the future of this field. I would be interested in approaching it from physics rather than math or comp. science. Now...

Particle/wave duality for starters. The electron 'particle' interferes with itself indicating it behaves as a wave.

About 160,725.935 miles. Closer even than the moon. The moon feels 4 times as much force from the sun as the earth.

Wow, I just found out I get a different teacher and hence not that book for stat mech next semester. Looks like I may have lucked out.

Well that's kind of what I figured, that it is pretty important. I will try the engineers next week, read up on them and hit up their office. Did the REUs you applied to actually ask for race/gender? Not all of them, Id say maybe half. If it was optional I elected not to say, but some...

WarPhalange: I have only pursued research opportunities in earnest for the last year or so (my junior year). They give varying reasons... they don't do research, they don't have anything a undergrad could do, they already have undergrads, they are going on sabbatical (seems like a quarter of...

maze: My current college in not great when it comes to physics, its ranked at about 50 or 60. I would like to do condensed matter. Something exotic like condensate would be awesome, but something more traditional would be fine too. I am probably best suited for experiment, but as I have no...

Hello, I am going into my senior year and am wondering if I can get into grad school... I know I am not getting into a top 10 school, I would like to go somewhere like U. of Colorado. I have a 3.6 GPA, and from pretests I expect to get between 650-750 on the GRE. However, I have not been...

I think I'd go for number 5, but I'll wait and see whether anybody agrees or not. That is what I picked too. I don't know if its right. Actually I don't know why I even picked it... I couldn't consciously find a pattern, so I just picked the one that 'felt' right. Can you post the...

The attachment is from an IQ like test. The last third or so of the test was quite hard. I look over the questions after the test, just for curiosity and still can't figure some out. Any ideas on what is going on here?

Ok, thx. The formula I was using seems to be for a moving listener not a moving source. I see how you justify making the vr negative. However it still seems odd since vr and v are going in the same direction, know what I mean?

Wait, centripetal acceleration is v^2/r. At the top of the circle neither v nor r change. Its circular motion.

Well, the source is moving toward you. So the direction of the sound and the source should have the same sign. I don't know. I am missing something small I am sure, because this is a GRE question so it shouldn't take long to solve.

Homework Statement A source of 1-kilohertz sound is moving straight toward you at a speed .9 times the speed of sound. The frequency you receive is: Homework Equations \nu = \frac{v}{\lambda} f' = \frac{v + v'}{v} f The Attempt at a Solution When I attempt the...
