Homework Statement Design a +10V supply with the following specs: Iout =0-100 mA Vout =10V Vin=20-25V (unregulated supply w/ ripple) The circuit will have the diagram attached. The book I am using is The Art of Electronics, which is very "practical" the authoppr says things like why worry...

yes, please, I'm quite interested.

Hi Hypersphere, thank you for your response. I was hoping there was some kind of "midway" model between the very difficult models and Debye/Einstein. I guess I will just have to go crawl back to Kittel(ugh) and Ashcroft/Mermin. If you were curious I'm looking into nanostructured thermoelectric...

I have found that DFT is a very popular way to do simulations involving solid state physics, however, from what I gather, it is not very "paper and pencil" friendly. I'd really like to develop a better intuition for how phonons and electrons move through crystals(would it be approporiate to...

We do have things like parametric equations which have a set direction and can curve through space, but they are not vectors, but more equations that could describe the exact path that say, a WWII era plane took while dogfighting. They can be set up as 3 equations, each describing a single...

I guess I'm really most looking for search terms I've realized. Also, as I've said I have access to Web of Science http://wokinfo.com/. If I do some search terms like "Solid State" & "Theory" I get experimental results or simulation studies. I cannot find the reviews that bundle up a series of...

I'm particularly interested in heat flow, phonons, things of that nature, I've already looked into the Debye Model and Einstein Model in Stat Mech. and Intro Solid State( side note, friends don't let friends read the more recent editions of Kittel). I ideally want to find the first papers that...

This is true, but why not compare a judo master to a simple machine? * Also, I never meant to bring skill into the mix, I was just using judo master before beacuse it sounds better than "practitioner of judo" or something.

Sorry, I just read it in my head as kind of talking down. Back on topic, maybe trying to model two whole people interacting is a lot (I'm a Sr physics major and that sounds daunting to me). Break things into little bits.

That kind of answer dosent really seem to help things, I think OP would have already thought of that before coming here to post. Why not try to set out a series of questions about a throw? As in, "In order to throw a 75Kg opponent in a parabola over his shoulder, how much work would the judo...

Hi Everyone, I was curious as to what the most current model in solid state physics is. I've studied the Einstein and Debye Models in Stat Mech, as well as free electron and tight binding models in an intro solid state class, but these models are rather old(which does not imply they are...

Hi Everyone, So I think this is a bit of a loaded question, but how do professional physicists find/learn the most recent models? I have been trying to find the correct search terms on web of science for the past few days, but so far I have only found papers dealing with experimental or...

Homework Statement (a) For the delta-function potential and with P<<1, find at k=0 the energy of the lowest energy band. (This is part A of Charles Kittel Solid State Physics problem 7.3) Homework Equations (P/Ka)sin(Ka)+cos(Ka)=cos(ka) (note, K and k are different variables) ε=\hbar...
