Nothing?

Hi, I'm studying for a course in semiconductor devices, involving pn-diodes, schottky-diodes and mosfet transistors. Just wondering if there's any good online resource that demonstrates specifically how to draw energy band diagrams for the various devices in various situations (applied...

I have measured some fluorescence emission from excited iodine and am now trying to do a Birge-Sponer extrapolation. I'm just wondering if the vibrational quantum number increases or decreases with increasing wavelength? In my instructions there's a plot showing how it might look, the linear...

You could be right, it's cool though ;). I tried replacing one of my hands with my forehead, and still felt that same feeling as I moved my palm towards or away from it. Not so much on my upper arm though. Guess I'll have to try some more. I suppose I could ask someone to try to move their palm...

I'm not sure if this is the right forum for this, anyway. I earlier read some thread, or on the internet somewhere, about people seeing auras. The explanation was that people seeing them had more connections in the brain which connected the senses, enabling people to see sound etc. I am an...

I think I understand now, thanks again!

Oh, I see. I partly understand but I'm still a bit confused, isn't the sum of the integrals of 1/x2 and -exp(-x^3)/x2 not the same as the integral of (1-exp(-x^3))/x2 ? Which means I should be able to calculate them separately and add them up? Thanks!

I thought it would be good to be far off since if the approximation (the far off function) is supposed to be less then ε, then the original integral should be much less then ε, right? Good suggestion, didn't think of it... remember though that the original function, f(x) is (1 - exp(-x^3))/x^2...

f(x) is the whole thing in the first integral and the rest is integration by parts. The primitive function of x^-2 is -x^-1 then I use integration by parts on exp(-x^3)*x^-2 by letting h(x) = exp(-x^3) and g'(x) = x^-2 which gives h(x)g(x) - ∫h'(x)g(x)dx. h(x)g(x)*(-x^-1) is the term that I...

Hi, I have an integral from 0 to ∞ and divided into two integrals, one from 0 to C and one from C to ∞. I'm trying to simplify the second integral so that I can solve for C to make the integral less than ε. \int\frac{1-e^{-x^{3}}}{x^{2}} = -xf(x) + \int 3xe^{-x^{3}} < \int 3xe^{-x} =...

1) I have no idea, how can I know without any prior experience? However, research seems interesting. The MsC in applied physics seems to offer laboratory-kind of research whereas I don't what possibilities a MsC in mathematics would offer. Mathematics is an interesting subject to study but not...

I'm an undergrad student in engineering with no work experience and limited knowledge about what's to come after I finish my studies. I still have a lot of time to decide, over 1 year more or less. Up until now I've been interested and fascinated by applied physics. More specifically...

Analysis in one variable, analysis in multiple variables, linear algebra, vector analysis (shared), complex functions/analysis (shared), some system theory, ODE (shared) & PDE and have had courses involving transforms (Laplace, Fourier) and Fourier series. By shared I mean that they squeezed...

Hello, I'm currently studying engineering in electronics (undergrad). A programme that has a lot of courses in physics and math. Soon I will have to choose a path (master) and recently I've been thinking more and more about choosing a master in mathematics. I like mathematic theory, fascinating...

I was just wondering, why do the energy equations look so alike? Refering to kinetic energy, the energy stored by capacitors and inductors, etc. My teacher in electromagnetism said something about it, that there's a reason for this. The energy is proportional to some rate of change squared?
