I should clarify that by strong program I really mean has an academic with a strong publishing record in the area. If anyone feels they can't answer as I haven't provided enough information or the question is too vague, please let me know.

Hey all, I'm looking to apply for gradschool in the US at the end of this year and I'm currently struggling to figure something out I was hoping someone here might be able to assist me with. I intend to apply to the top 10-15 schools, but given the cost of applications, for universities...

Thanks Someone, I think that sounds like the best approach.

Hey all, I'm currently facing a difficult decision about the next step in my academic career and I was wondering if anyone here might be able share any insights or perhaps explain how they got through a similar situation. Sorry in advance for a long post, no need to read the whole thing...

I'm an Australian law/science undergraduate. I finish my degree at the end of this year and was hoping to apply for Grad School in the US to study Physics in 2011. As I understand it, the key requirements are the general GRE, physics GRE and the actual applications to the universities. I have...

Thanks for the help, I think that sorts it.

Homework Statement Let X be a metric space with metric d. Show that the space X, where distance is measured by d' = d/(1+d), is also a metric space. Homework Equations Three requirements of a distance function for X to be a metric space: 1. d(x,y) = 0 <=> x=y 2. d(y,x) = d(x,y) 3...

Any thoughts?

1. Invariants in field strength The first part of the question asked you to calculate the Lorentz scalars by contracting the field strength tensor (F) and it's dual (G): FF, GG and FG (index's omitted) and formed ±2(B²-E²/c²) and -4/c(E.B). The next part asked: Are there any other...

I'm currently undertaking a course in Solid State Physics and my professor has asked us to undertake some work in the free software 'Octave'. I have not had any programming experience in my life and I am feeling very much out of my depth. The lecturer gave us an initial file with the relevant...

Hi all. I've just come across two issues in some problems I have been doing and although I know the results, I can't remember the reason why or how to show it. Hoping someone can point me in the right direction. Homework Statement 1: lim[n->∞] f(g(n)) = f(lim[n->∞]g(n)) 2. Integral...

Thanks for the help, it came out.

Doing an Analytical Mechanics course and we're just reviewing some classical physics and this question came up. Cheers for any help. Homework Statement A gun can fire shells in any direction with the same speed v. Ignoring air resistance and using cylindrical polar coordinates with the...

Homework Statement A coaxial cable consists of two long, concentric, perfect conductors. The inner conductor is a right circular cylinder of radius a, while the outer conductor is a thin, hollow annular cylinder of inner radius b. Suppose a half-infinite length of such a coaxial cable...

It's just a standard integral for arcsec... :S don't know how I missed that. Thanks for the help
