I'm pretty sure vanadium_50 is much older and wiser than me, but I agree.

Yea, special class for the smart ones.

Looks like freshman physics. They look a little harder than the class I took as a freshman, which explains why it's an honors class. It doesn't look like a junior level class to me.

I think you're looking at this problem the wrong way MetalManuel. It's much less about knowing basic physics and much more about being able to write statements to describe mathematical relationships. You really don't need to know anything about physics except for the equation for a parallel...

You're on a perfectly good track then. Keep doing what you're doing.

Lyx has worked well for me in the past.

Is nobody familiar with this method? I only need a brief explanation of how it works. The explanation I have in my text says "solve the planar problem in the x direction to obtain neff(y). Then solve the planar problem in the y direction" I just don't understand how to get n effective as...

Wow the last two comments made me feel great about my life. Now I understand why I live 3 hours away from my girlfriend so that I can work at least 12 hours a day so I can get a job that sucks.

Yes, the average person with a PhD in physics would be able to solve that no problem.

Homework Statement Is anyone familiar with the effective index method for rectangular waveguides? I have a waveguide for which the width is much greater than the thickness. I think I need to start by treating it as a planar waveguide. But I am supposed to get an effective index which depends...

So that only the hardcore get graduate degrees? I dunno, it sure seems like they are trying to kill me sometimes though.

You have a solid 8 years of math and physics background before you can start to think about particle physics. Here is a free copy of a QFT book, maybe it will give you an idea of why you need to learn so much background before you can do particle physics...

1st year graduate classes.

This has bugged me for a long time, since I was an undergrad. What is the best strategy when doing challenging problems sets? And, what strategy do professors think you are using? When doing problem sets by myself, I will invariably get stuck on one or more of the problems. Now, I am not...
