Hello. I'm an undergraduate physics/applied math major hoping to go to grad school. I have a professor in my school who I'm interested in doing research under because the subject of his research is, well, interesting to me. Also I'm consider it in graduate school. I had him last semester...

Ah, I see. So the general change of energy formula for non-conservative forces follows from the work-kinetic energy theorem. And that ##ΔKE=-ΔPE## for free fall follows easily from this. Great explanation! Thank you both a lot! It makes so much more sense now.

Okay, that makes sense to me. So you're saying that the total energy of the mass doesn't change (because gravitational force is conservative, implying no loss of energy) but the net external work done on the mass is non-zero, so the equation is incorrect in such a situation. Am I correct in...

Hello there. I've yet to take a theoretical mechanics course (next Spring) but I've been reviewing my intro level class and I've run into some confusion regarding the work-kinetic energy theorem. My textbooks state that W_{net}=ΔKE And this makes sense to me: the net work being zero...

Thanks for responding! I did work last Fall with a professor and a classmate of mine, but started at my internship in the Spring and was left without time to continue that research (financial decision). I'm hoping to work with a math professor at some point this year, and there's one physics...

Hello, this has been concerning me for a while now. I've seen online many testimonials about how important recommendation letters are for acceptance into a graduate program. I only have minimal research experience as of now, and I'm currently working at an internship I will likely be...

Sounds like a fun project regardless! And yeah, I was planning on spending a while on this. By "custom" I meant like planning it all out, making sure I got the dimensions correct, choosing good wood, coloring, and ultimately adding some details to it to make it look unique (e.g. metal piping...

Thank you both for your informative replies. I hadn't much considered the competition and funding issues. That's disheartening, but it's better to know where I stand now rather than later.

Thanks for all the input! I have a list of "to-read" books ready to go now, and I purchased a copy of the excitingly-cheap "General Relativity from A to B" to read in my spare time. I'm trying to examine my prospects for the future if I continue on to study relativity/cosmology type physics and...

Hi everyone. I'm looking to take up electronics as a hobby. I also play the electric bass guitar and I've been seriously contemplating building my own in my spare time. The ominous woodworking aside, I was wondering if anybody had any experience with building instrument electronics from...

Not yet, I haven't. I was led to believe that those were generally graduate level courses?

Hello all. I'm a third year physics/math major and I'm trying to figure out what area of physics to go into for my graduate studies. I'm interested in something very mathematical, and I would like to learn more about relativity and cosmology in general. It's all a gigantic wealth of...

Hello! I'm an undergraduate physics and math major and I just finished up my third year at a small university. I plan on staying an extra year to fulfill all of my requirements, so I have over a year to figure out exactly what I want to do in the future. I'm pretty set on going to graduate...
