Welp. That someone was me. Guess I have three more to wait for... Thanks for that update.

I got rejected from both the Duke/TUNL Research REU and the University of Michigan (CERN) REU aready. :(

Thanks for replying, but what do you mean that gold doesn't change on heating? Do you mean its conduction? And does such a property remain unchanged for only low-temperature differences, or for even high temperatures?

Hey all, I've been thinking of a couple scenarios that involve thin wires (ones that have their diameter in the order of 1 mm). Suppose a gold wire with length L and diameter D is suspended straight in room temperature air and connected to some voltage V. Thus, a current will pass through the...

Yes, it's beta decay. But, unfortunately, I haven't taken any quantum mechanics courses yet. I know the concept and some general examples of the Hamiltonian, but I do not know what "take H(i to f)" means.

Hey, here's a quick question: What is the Hamiltonian operator corresponding to a decaying Carbon-14 atom. Any insight is quite appreciated!

I looked at Brown University and here's what I've found. Brown's Physics department currently employs (from what I've found) at least five theoretical particle physicists (their research includes string theory). Compare this number to MIT's and Princeton's thirteen. Now, only seven paper's from...

You got to love it too. To me, it is the biggest prerequisite. It seems you love cosmology, which a step in the right direction.

It's all about perspective. I don't find these thing to be random; they are what they are. You may find these physical traits to be random and unrelated, but physicists try to make sense of these facts and relate them. For example, the permeability of free space ( the μ0 constant within the...

Hey guys, just curious of your opinions on this matter. Which graduate schools are the best to earn a Ph.D. in physics theory from and research in concerning the theoretical sub-fields Quantum Field Theory, General Relativity, and Elementary Particle Physics (maybe String Theory)? Which has...

Hello, I am currently a sophomore double majoring in Physics and Math at Purdue University. I have a 4.0 overall GPA and would love to earn a Ph.D. and probably a postdoc position in the future. But what should I concentrate in? To which graduate program should I set my eyes on? Here are...

Combat Special Relativity before you face that monster of a subject.

I would highly recommend Matter and Interactions Volume II or Feynman Lectures Volume II. They're so awesome I keep both of them!

Here's a helpful hint that may help you. The determinant $$\begin{vmatrix} 1&5&-2 \\ 3&-1&0 \\ 5&9&-4 \end{vmatrix} = \begin{vmatrix} u_x&u_y&u_z \\ v_x&v_y&v_z \\ w_x&w_y&w_z \end{vmatrix}$$ may be rewritten as $$\begin{vmatrix} u_x&u_y&u_z \\ v_x&v_y&v_z \\ w_x&w_y&w_z \end{vmatrix} =...
