please correct vi=3.vi to be vf=3 vi, so now the problem is solved..

do anybody knows about allowing some ports if I am behind the firewall? I mean making a hole in the firewall?

can I get Gnuplot for windows?

hi guys could you please tell me a freeware FTP server with which I can share my files with my friends..,, cu

this is the apt answer to the initial question...well done..

I just want to add the fact that quanum mechanical spin is different...there you can't assume an electron rotating unlike classical physics...here the rotation means quantum mechanical transformation in Hilbert space... c ya

Faster than c! hi I read that the refractive index(n) for X-rays in meterials are less than 1(very little less than 1). I got confused ..I am using X-ray reflection at the moment. But I am not convinced by the fact that n<1 means faster than c(velocity of light in vacuum or in air)! hope...

quantum spin is a quantum mechanical state. It has nothing to do with the spin in the real macroscopic Newtonian world. For instance electrons has 2 spin states (+1/2 and -1/2), that doesn't mean that the electron is rotating with different Angular Momentum directions! The angular momentum and...

I am sorry.. I think you people didn't understand my question.. If you have a beam of nuetrons falling on a thinfilm the neutrons will get scattered. The strength of the scattering is proposional to the scattering length(the neutrons feels a Fermi potential, which is propotional to the...

what is the physical meaning of the scattering length of neutrons? What does mean -ve scattering length( for instance for 'H' !)?? :smile: :smile:

no no...it is used to simulate the reflectivity profiles(X-ray and Neutron).

I am not sure whether nano clusters can be defined as a group of nano particles..as far as I know clusters are group of atoms(it can start from 3 atoms) to 10,0000 atoms or even more large enough to be called as a bulk matter!...but nano particles can be of same dimension..is n't it? if you call...

what are the differences between nano particles and nano clusters?

I know how to do it..just asked if somebody has more ideas... :biggrin:

hello I need more ideas about the normalization of functions..like Guassian.. I think this is to make the possibility of all events =1.(like in Q. mechanics we normalize wavefunctions). So the area under the curve is constant.. if anybody has more ideas please reply manesh
