I didn't apply to any so I'm not doing any REU. I have a friend who did apply and he'll be going to the new spallation neutron source this summer. He got accepted quite awhile ago (first or second week of March). I'll be working in lab this summer with a professor. I'll be measuring...

EE group at my univ is working on quantum dot (for quantum computing) and physics group is working on Rydberg atom implementation. So EE need to know quantum mechanics and solid state physics too! The main difference is EE don't need to learn QFT or particle physics. It depends on what you...

I think most engineering and science majors can be difficult depending on how far you actually go. Often you'll need to be proficient in other areas as well. Ultimately you just need to choose something you enjoy (or something you think you'll be able to complete).

I don't think you'll see photons replacing electrons in intergrated circuits. they tried this before (as in trying to route photons) and it didn't work too well. main reason is light likes to go straight. if you want to build a realistic cpu, you're going to have a lot of "corners" and light...

I'm not sure why you would focus on circuits if you're doing optoelectronics. I think optoelectronics is mainly about how to build better devices by exploiting material properties, device structure, etc...

I see. We never really went over CG table so I had to guess the first form and generate rest of the spin (or orbital angular momentum) states. Thanks for the clarification.

I have a general question on finding momentum states Let's say I have two spin 1/2 particles, so J=S_1+S_2 and |J| ranges from |S_1 + S_2| to |S_1 - S_2| in this case J=1 is triplet and J=0 is singlet. Now how do you find the J=0 state? I know that...

photon is a boson (identical particle) so you can't distinguish which photon it is. I haven't dealt with photons in quantum mechanics yet, but my guess is it's just reflected.

I'm majoring in EE but I'm also taking a lot of physics classes. I chose EE as oppose to physics mainly because I think engineering is more marketable. You won't learn any theoretical physics from engineering for sure, but most EE programs will cover electrodynamics, plasma, and solid state (for...

well I don't *have* to use the expansion to do the integral. I guess I'll the integral directly first and see if I can understand how this expansion works (suppose to make the integral easier).

I'm doing Griffith Problem 5.11 and I'm stuck on how to do the integration. My prof. gave hints on how to simplify the integration with the following formula: \frac{1}{|{\vec r}_{1}-{\vec r}_{2}|} = \sum_{\ell = 0}^{\infty} P_{\ell}( \cos \theta) \frac{r_{<}^{\ell}}{r_{>}^{\ell +1}} where...

I'm having problem with griffith QM problem 4.43: Construct the spatial wave function for hydrogen in the state n = 3, l =2, m = 1. Express your answer as a function of r, \theta, \phi, and a (the Bohr radius) only. My prof. gave hints about radial wave function, but I have no idea how to...

looks like X~Normal random variable.. why does your EX have x^2? to integrate exp(-x^2), you need to use a trick. multiply integral by itself to form a double integral... result should have exp(-(x^2 + y^2)) as part of integrand. recall x^2+y^2=r^2 and dx dy = r dr d0 but i don't think...

thermodynamics is not required for EE at my university. of course it depends on which part of EE you're doing. I'm working towards photonics so quantum mechanics and statistical mechanics are recommended. you can always try to cover rest of the book on your own (and consult professor if you run...

I'll be senior (credit wise) next semester and I will take freshmen chemistry. I took physics every semester and neglected chemistry because chemistry was not a requirement for comp sci/engr. Now that I switched to electrical engineering, I have to take it. It will be an odd experience since I...
