This seems reasonable.. Thanks! Naftali

Hi, I have posted this question to "classical physics" forum, but now I think this forum might be more appropriate. I have no idea how to move the thread here, so here is a copy.. The question seems trivial, but I want to check if I miss something. Homework Statement I'm trying to...

Thanks anyway..

Thanks you all for the answers. nasu - sorry, despite my tries I don't get this result (and I tried another calculator..), I will be thankful if you can show your calculation process. Thanks

It should be (3\pi^{2})^{2/3} instead of 3\pi^{2}

Homework Statement Two questions : 1. find the (mass) density of Sodium. Atomic weight: 22.9898. Crystal structure: bcc. a=4.23 angstrom (crystal constant). 2. Given the (mass) density of Aluminum : 2.7 g/cm^3. Atomic weight: 26.982. Find the number of atoms density (# of atoms per cm^{3})...

Thanks for your response. Can you describe its advantages over Sakurai? Thanks, Naftali

Hi, I'm looking for a QM mechanics book, which I could use for review and reference. I've took 3 QM courses, the first two was based on Cohen-tannoudji and Sakurai, and the third was about atoms and molecules etc. , although I haven't studied scattering theory and relativistic QM/QFT. (I took...

Hi, Thanks for your answer. Actually the question is to find the potential of this charges far from the origin,so I guess I should transform the dipole moment vector only.. Using the identity for the delta function I get weird things like exp(arccos (x/d))... It is just interesting if the...

Homework Statement Hi, This is supposed to be simple, so I guess I miss something.. We have charge q at x1=d*cos (w*t), y=0, z=0. and charge -q at x2=-d*cos (w*t), y=0, z=0. I need to do Fourier transform to the charge density. Homework Equations The Fourier transform is ...

Hi, I'm about to finish a BSc in physics next year. Unfortunaltely, I'll probably take a break from physics afterwards. I am looking for a book or books which will keep the material fresh while I'll not be in studies. For comparision of the level: our advanced mechanics course was according...

Thanks , I will try to look at this books in the library. We don't have Melia and Franklin there.

Hi, I take a second course of electrodynamics, one of the main subjects is e.d and relativity, the lecturer use Jackson as the course's textbook. Is there any other book which covers this subject in the same level as Jackson which is more friendly and can be used for self-study (Jackson is...

thanks, I was searching for "reverse FFT" while the correct is "inverse FFT"

Hi, I'm analyzing a laser diffraction experiment. Does Matlab has a reverse FFT function? Thank you Naftali
