Hello everyone, and especially people who are doing Electrical Engineering. I am doing M.S Physics now, almost finished first year but I realize that research at higher level is not my venue. I suck at it. While undergrad i took some mech eng and mat science classes, however my funds were...

Look at " Electromagnetic FIelds and Waves", by Lorian and Corson. Amazing Electromagnetism text! Quantum Mechanics, I really like text by Robinett. ( I wish I had anwsers to some of his problems)

Kibble is undergraduate Text, Goldstein - gradute. If you feel adequately prepared go with Goldstein, otherwise buy Kibble. It is great to review Undergrad Classical Mechanics. Plus it as lots of very interesting problems.

Thanks! Talking to someone from university is interesting idea.

Some graduate schools I am applying to require both while do not give specific directions of what to include in each . This lack of directions makes me very confused about what to put in each category. I have done some research and have rough idea, however I am not sure. So if you can help me I...

Hi guys, there is a problem I am having hard time interpreting, so I wonder if you can share your thoughs. Here it is. Homework Statement a projectile is launched due north from a point in colatitude /theta at angle pi/4 to the horizontal and aimed at target whose distance is y (small compared...

So tensors is not that critical. Any suggestions what book has the best treatment of greens functions as well as PDE?

Any suggestions on good Tensor Algebra book?

Hello everybody. I would like to ask anyone who have taken graduate electrodynamics with jackson. What do you think is the best way to prepare yourself to graduate electromagnetism by Jackson, if only electromagnetism by Griffith is covered during undergrad. In particular, what...

I figured it. By finding the distance of closest apporach and setting it to the Radius of a star R. From there I obtained the value of impact maximum parameter b for which particle will still collide. After that the problem gets very easy. Thanks for help

thakns!, it is just Pi*a*b/year, dam I am retarded..

It was one of my guesses. If the second keplers law is used than dt=constant/da= J/(2*m*da) . I just fail to see why suddenly Pi appears in the denominator, as if they divided area by a*b*Pi

Hi everybody, thank for helping with previous problem. I have another quesion: This is not an actual problem. While the problem is actually solved in the book one of the steps there is not entierly clear as a result I cannot understand simmilar problem. So here it is Homework Statement...

Thanks for reply, Sorry,I should have been more specific. Tthe problem states that you have to show that rate of mass accumulation is described by following equation: dm/dt= pi*rho*v*(R^2+2*G*m*R/v^2) where R is the radius of the star and v it's velocity. Also the problems asks you to...

[b]1. It is problem for kibble book, classical mechanics. I star with mass M traves through cloud of particles with density ro. Particles that collide with a star are trapped by it. Derive the expression for mass increase of the star dM/dt. The Attempt at a Solution Since all particles that...
