I finished my undergrad last year and joined this phd program in fall. I passed the qualifiers in December, and over the two semesters, I have completed all the necessary phd courses, taking no master's courses. Early in the year, I was contacted by a Professor in hep-exp to try out his group...

This may seem like a naive question to some people. I had always heard that Lqg can easily incorporate supersymmetry---that if there were any evidence of it, putting it into the theory would be straightforward. This goes way back, to papers I read in 2003-2005. Not sure exactly which, but it...

I would like to study Maths or Physics for my undergrad and eventually, go to grad school. I can't possibly know if I'd want to go to grad school in science and I'm just curious with regards to what it takes to get into a Finance PhD program. For maths/physics, it is my understanding that very...

This is part of the simulation program in Antenna field pattern. One part involve finding the position of the peak where: AF=\frac {\sin\;Nx}{sin \;x}\;\hbox { where N is an integer.} The peak is at x=0 and the AF=N. But excel do not accept this and call out as "DIV 0" error. Is there any way...

I want to study antenna patterns of different arrangements. I am looking for a very cheap software ( free is even better) to plot graph if I provide the \;R,\theta,\phi. Even if 2D plot would be helpful like keeping either \;\theta\;\hbox { or }\; \phi\; constant and vary the other angle to...

Hi, I live on the East Coast (USA), and I'm looking into transferring from the college I'm at because it does not have a decent physics program/department. Does anyone have any recommendations for unis/colleges that have really good ones? (I'm not talking MIT, Harvard, etc. I know I...

I'm about to start a PhD program at a top 5 school but I'm just not feeling excited about it. I feel burnt out and I've lost my enthusiasm for physics. As an undergrad I worked ridiculously hard and sacrificed my social life for physics and I just feel like I can't do that for another six...

Call me paranoid if you will, but is there any handy tool that keep a track or can find out what program that has a possibility/ability of internet connection, has visited what directory by what time? It could be a stand alone software, could be something that comes with windows. Does anybody...

I just took my balance in my 401K program out of all stocks, bonds, and corporate stock funds and put the into FIXED. I never thought I would see this day happen, but what I see (not happening) in Washington in addressing the debt limit gives me cause for concern. IMHO, it is better to...
