How to derivate Maxwell Boltzmann Distribution

AI Thread Summary
The discussion centers on the derivation of the Maxwell-Boltzmann Distribution, with the original poster expressing dissatisfaction with existing online resources. They seek clearer explanations, particularly regarding the mathematical steps involved in deriving the distribution function, especially the derivatives related to velocity components. Participants suggest that knowledge of statistical mechanics could be beneficial and encourage the poster to clarify specific areas of confusion to avoid redundant responses. The conversation highlights the complexity of the derivation process and the need for more accessible resources. Overall, the quest for a clearer understanding of the Maxwell-Boltzmann Distribution derivation remains a central focus.

Hi PFers. I am interested in Maxwell Boltzmann Distribution. I have searched in Internet for the derivation but I am not satified with them. Can somebody show me the way to derivate it? Thanks.
ψ(v)=(m/2*pi*kT)^(3/2) e^(-mv^2/2kT)

There are many ways to derive it - some more insightful than others.

Have you taken/taking stat mech?
 
Thanks for the answer.
I haven't taken Statistical Mechanics but Statistics. Could it be useful for this?

It would help if you tell us why you are not satisfied. Then people won't waste time pointing you to the same things again. :smile:
 
Thanks. Yeap, here.

Sorry I haven't used LaTeX well enough to type it here again. At derivation of ψ(v)=f(vx)f(vy)f(vz) by taking derivatives with respect to vx, it is very unclear to me. I think dψ/dvx = dψ/dv * dv/dvx. And after that I don't know how to solve it.

This seems better and easier. At the part argumenting for spherical shell, there are a lot of values of vx/y/z so that give the same value of v!? And the application of function g(v)=\alphav^n * e^(-\betav^2) is a bit evidencelessly.
 
Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'
So here is the motional EMF formula. Now I understand the standard Faraday paradox that an axis symmetric field source (like a speaker motor ring magnet) has a magnetic field that is frame invariant under rotation around axis of symmetry. The field is static whether you rotate the magnet or not. So far so good. What puzzles me is this , there is a term average magnetic flux or "azimuthal mean" , this term describes the average magnetic field through the area swept by the rotating Faraday...
