Maxwell distribution solely using the Stosszahlansatz and geometric transformations?
Background
To quote Wikipedia:
The assumption of molecular chaos is the key ingredient that allows
proceeding from the BBGKY hierarchy to Boltzmann's equation, by
reducing the 2-particle distribution ...

Wien on Temperature and Entropy
As far as I understand, Wien defines entropy, which he uses in his derivation, as
$$ S = \text{v} \int\limits_0^{\infty} \varphi(\rho, \nu) d \nu, $$
where $\text{v}$ is the volume occupied by ...

Boltzmann’s original derivation of the Stefan–Boltzmann law
Does anyone here know a source where I can find Boltzmann’s original derivation (using primarily thermodynamic arguments) to the Stefan–Boltzmann law (the radiant power emitted by a body in thermal ...

Translated publications of Boltzmann
I have been looking for Boltzmann's papers (in english) and had no luck. Anyone knows if they were translated at the first place, and if yes where to find them?

Thermodynamics of binary symmetric channels
I am reading this very interesting paper:
http://m.iopscience.iop.org/1751-8121/41/40/402002/pdf/1751-8121_41_40_402002.pdf about thermodynamics of channels in information theory.
More generally, ...

What is the origin of the kinetic theory of temperature?
Count Rumford's experiments with canon barrels are often cited here, but the kinetic theory certainly precedes them. Another candidate is Daniel Bernoulli, who, in his 1738 book Hydrodynamica showed ...

Fitting van der waals law on real data
For an examples class on thermodynamics, I would like to fit Van der Waals law on data of real gasses, say $CO_2, H_2O_2, CH_4$.
I want to set out measurements of pressure and volume at constant ...

Confusion regarding entropy, reference papers request
1.a In paragraph at Wikipedia/Entropy it is stated:
This is because energy supplied at a high temperature (i.e. with low entropy)
tends to be more useful than the same amount of energy

Reference paper to support information -- energy relation $\left(kT \ln2 \rm\frac{J}{bit}\right)\;.$
In answer to Maxwell's Demon Constant (Information-Energy equivalence) there is stated that one bit of information allows to perform $kT \cdot \ln2$ Joules of work. Which paper supports the thesis?...

Deriving an Expression for Entropy
How to derive an expression for entropy in form of
$S = \ln \Omega$
from the form
$\displaystyle{S = - \sum_i \; p_i \ln p_i}$ ?
That is the last formula taken as a definition of entropy.
Just a ...
