I do embedded software for a living and if you aren't already familiar with the concepts then it is an incredibly important course. As mentioned, higher level languages have libraries to provide the functionality but it is necessary to understand the hows and whys of the structure in order to...

Hi all, So, I'm finishing up my master's degree in applied physics (not much different from a master's in physics if you choose your courses correctly) and am looking into Ph.D programs. One thing I haven't seen much information about is the requirements if you are coming into the program...

Homework Statement The original problem is determining the dispersion relation of an ordinary wave in plasma damped by collisions. That part was easy enough but the next part is to find the damping rate (-Im(ω)) of the wave, assuming k is real and \nu << \omega where \nu is the collision...

http://ocw.mit.edu/OcwWeb/Physics/index.htm There are a few universities doing similar things (offering notes/homework from courses online) but most if not all require a textbook of some sort. If you feel like skirting the law a bit, there are a large number of physics books availible...

Marion and Thorton was used to teach my Theoretical Mechanics course, and it included Hamiltonian and Lagrangian stuff, orbital mechanics, etc... so I'd say, yes, it'd be use to teach an upper level undergraduate mechanics course.

I'm not a graduate student, but I have asked this same question of those in the lab here with me. It seems that with classes, research and studying they put in about 40-50 hours a week. However, there are also long stretches of time where the experiment is on hold, waiting on another school or...

Thanks for the advice so far, everyone. I've thought about staying put, as it is a great school in a very nice town, but I know my advisor highly frowns upon it. I may talk to him about just staying for a year or two, assisting the same professors I do now, just to show that I can do the...

Hi gang, As a rising senior, I'm very worried about what the future holds for me. Like most of my class mates, I would like to attend grad school for physics. Unlike most of my class mates, my academic history leaves much to be desired. I am graduating two years late due to a change of...

Remember, that something like 1 / x is equal to x^-1. You can put everything in the numerator, and then use the product rule first.

Hi gang, I'm having trouble with doing a derivative of the Gamma function. I know both the definition of Gamma and Polygamma, but can't see how to get from the derivative of Gamma to Psi times Gamma. Any help or hints would be great. Thanks!

Thanks guys, managed to get it figured out.

Hi all, I'm working through a sample midterm and I managed to get everything correct except for two, which I am a bit stuck on. Here is the first one: A 1024Hz tuning fork is used to obtain a series of resonance levels in a gas column of variable length, with one end closed and the other...

We are actually using gauge pressure, so it simplifies the formula you gave a bit. I did get the correct answer using your method, though, so thank you very much.

From the side, sorry.

Hi gang, I'm having an issue with one my homework problems. There is an L shaped tank, 3d in height, 1d in width. The verticle part of the L is 2d in height, and the horizontal part of the L is a 1d box. d = 8m _ | | | |_ |_ _|<--Force due to pressure needed for this side. I need...
