Hello all, I am a soon to be PhD graduate with experience making nanoscale size graphene and carbon nanotube devices and studying their properties. I want to continue working with and manipulating tiny things, but want to move closer to something applicable and marketable. I also love cars...

If you want to get a good start on understanding the subject matter and achieving high grades, there is no better way to do this than read your mechanics textbook now. If you manage to simply read the entire textbook leisurely and go through examples, you will have an incredible upper hand over...

Both are amazing opportunities, so really either choice you go with will be a great experience. Its likely that Lawrence Berkeley will have more extravagant projects but really you should look specifically what projects each program offers, and choose what you are more interested in. One up...

Thanks for the responses. Does anyone have personal experience with this? I have a feeling that I will have to choose between going to a school with mediocre/poor physics department (where I already got in with funding), or waiting it out and improving my GRE scores to take another stab at it...

Well, as the rejection letters start coming in, I can't help but wonder what it takes to reapply to graduate programs. I believe my application this time around was strong in all aspects except GRE scores (which were quite miserable). So my question is, if I improve my GRE scores significantly...

This is the damped kuramoto-sivashinsky equation.

So I suppose my Fourier knowledge is a little bit rusty. Any help would be greatly appreciated. http://pmgz.net/3259.jpg How do they get from the original DKS equation to the Fourier space DKS equation (from eq 1 to eq 2)? Thanks greatly for any help.

Interference can be easily photographed by looking at some oil on water. The oil forms a thin film causing the interference. Also can be done with some soap bubbles or something.

I too have not heard back from 2 REUs yet. At this point though I am pretty much accepting it as a denial, since many of those programs start within weeks.

First step to any force problem is to draw a free body diagram. Have you gone this far?

I just received a rejection from UCSD yesterday. I am really quite bummed about that since it was my #1 choice. So far that makes 2 rejections and 4 MIA. :(

Bump. Anyone hear back from anywhere?

I applied to about 6, and like others here only have heard back from UMichigan. Rejection. :(

Yes, because essentially what you are doing in the first drawing is A + B + (-C), whereas in the second drawing you have B + (-C) + A. This is perfectly fine since vector addition is commutative (it doesn't matter what order the vectors are added in).

As I recall, chain rule goes like "Derivative of the inner function multiplied by the derivative of the outer function evaluated at the inner function".
