Entropy of blackbody radiation

AI Thread Summary
The discussion centers on the equation S = v∫₀^∞φ(ρ,ν)dν, relating to the entropy of blackbody radiation, which is derived from concepts in statistical mechanics. Participants suggest that this equation is not original to Einstein and recommend consulting standard statistical mechanics textbooks like Schwabl or Greiner for deeper understanding. One participant admits to limited knowledge of statistical mechanics and seeks guidance on suitable texts. Greiner's book is highlighted as accessible and rich in examples. A solid grasp of statistical mechanics is deemed necessary to fully comprehend the equation's implications.

Can someone point out any information (derivation or where it comes from) about this equation:

S = v\int_0^\infty\phi(\rho,\nu)d\nu

\nu is frequency of radiation. \rho(\nu) is radiation energy, v is volume.

I'm getting this from Einstein's photoelectric effect paper.

Thanks a lot!

Well,i haven't seen it in this actual form.Surely it wasn't an invention by Einstein.Did you check the formula for the entropy of BB radiation in a standard SM textbook,like Schwabl or Greiner...?Can u see the connection,then ?

Daniel.
 
No. I haven't studied statistical mechanics (beyond very basic ideas of entropy), and don't have a text to compare.

I figured I'd probably need to have a good understanding of statistical mechanics before I could get through this paper.

edit: Which SM text would you recommend?

Greiner's book in his series seemed accessible / readable enough and provided a wealth of worked out examples.

Thread 'Thermo Hydrodynamic Effect'

Thread 'Thermo Hydrodynamic Effect'

Vídeo: The footage was filmed in real time. The rotor takes advantage of the thermal agitation of the water. The agitation is uniform, so the resultant is zero. When the aluminum cylinders containing frozen water are immersed in the water, about 30% of their surface is in contact with the water, and the rest is thermally insulated by styrofoam. This creates an imbalance in the agitation: the cold side of the water "shrinks," so that the hot side pushes the cylinders toward the cold...
