In 1900 Planck followed Boltzmann's method of dividing.
Planck suggested that energy was radiated and absorbed
with discrete "energy elements" - " quantum of energy"-
- " Planck's action constant"- (h) . Its energy is: E=hv.
3.
In which reference frame does this process take place?
In thermodynamical reference frame of ideal gas and
black body (Laue called this model as Kirchhoff,s vacuum).
Now it is considered that these models are abstract ones which
do not exist in nature. On my opinion these models explain
the situation in the real Vacuum (T=0K) very well.
4.
For my opinion the formula (hv = k logW ) says:
a)
The reason of " entropy" , the source of thermal equilibrium's
fluctuation , the source of Vacuum fluctuation is an action of
the particle /electron, which has energy: E = hv.
b)
The process of Vacuum fluctuation depends on collective
motions of all particles (k) and will be successful if enough
statistical quantity of Boltzmann's particles ( k logW)
surround the electron.
c)
Which process does the formula (hv = k logW ) say about ?
This formula explains the beginning conditions of gravitation,
the beginning conditions of star formation.
( The article of star formation is posted on this site.)
d)
One physicist said :" The entropy is only a shadow of energy“.
Maybe now somebody can understand why entropy is a shadow.
And maybe now somebody will understand why
" The Law of conservation and transformation of energy"
is also correct for thermodynamic system.
===========..
P.S.
It took me only two month to write this brief article.
Plus about three years searching for the key of entropy problem.
Plus about twenty-three years trying to understand the essence
of physical laws and formulas.

Best wishes.
