Obviously this is anecdotal, but still useful: I did my undergraduate degree at a regional private liberal arts college, i.e. not even in the national rankings. It's a good school and I received a great and broad education in physics and especially in the liberal arts. I got into a...

I concur with the above responses. Why not both? :biggrin: Seriously, there is probably no better choice of double major for a physics or math student. The two subjects will complement each other nicely, and you'll gain a better understanding of each one by studying the other. And your grad...

OK! I think you have a good understanding of this problem now. Let me know if you have any other questions.

You're confusing terminology. Here, \mu is the magnetic permeability of the medium inside the solenoid. It's safe to assume vacuum if a specific material is not given. As for n: Remember that the single wire loop encircles the total magnetic field generated by the solenoid, which depends upon...

Yeah, you're on the right track. Remember \mu and n are not units but quantities that have specific values for the problem.

Through a closed surface, yes, the integral is zero. That is not necessarily the case for an open surface, like the area enclosed by the ring in this problem.

I think you have the wrong equation for magnetic flux. Flux is not defined by the line integral of the magnetic field. Magnetic flux is a measure of the amount of magnetic field that passes through a given surface/area. If the area of the Surface is a and the differential unit vector normal...

As a graduate of a small liberal arts college, I wholeheartedly concur. The school I went to was a regional liberal arts school (a tier below places like Amherst or Swarthmore) but I was also more than adequately prepared for my PhD. I'd even go so far as to say that the extra focus on the...

It's somewhat arbitrary I think. It even happens with some masters degrees. My graduate program actually did not offer an M.S. (or M.Sc.) in physics, only a masters of arts (M.A.) or a Ph.D. The M.A. degree did not require a thesis component. So perhaps this is why it was not called an M.Sc...

Teaching new material to yourself is not easy, especially in physics and mathematics. I'd suggest you not worry too much just yet. Take the physics intro sequence when you get to university. When you are in a course with more resources, a professor, and other students to work with you might...

This. Any qualified candidate should be able to find a program to fund their PhD through assistantships. It doesn't matter how prestigious the program or university. I'd never tell any physics grad student to attend a graduate program that didn't offer them funding.

I'm sure this has something to do with it. I have had time off over the past 5 years, but usually that involved visiting family. While my family is great, there is enough negative dynamics involved to make family visits less than relaxing. I just don't have the money for a real, escape from...

Hi All, Hope all is well. It's been a while since my last visit to PF. I'll cut to the chase: I'm now in my 5th year of grad school, and I basically feel like crap. On the surface, things seem fine. I have two papers published, another accepted for publication, and a fourth in the revision...

FBI is involved as well. Bomb squads...

This is insane. Every cop in Boston is out tonight. One MIT officer dead. Reports of another down. Police and SWAT with assault rifles all over the subways. Explosions heard in Watertown...
