comment Calculation of the differential of the entropy
For completeness of future readers we should also say that $\tilde{S}+\sum_{i}P_{MB}\left(i\right)\ln\left(P_{MB}\left(i\right)\right)= \tilde{S} -S_{MB}=dS$ right?

comment Calculation of the differential of the entropy
So you are saying that $\sum_{i}dP(i)=d\left(\sum_{i}P(i)\right)=d\left(1\right)=0$ ?

I can't see how to multiply the two $dP(i)$.

comment Calculation of the differential of the entropy
You are right, for the total probability they are both equal to 1, so they cancel each other! So I remain with the differential in argument of the logarithm

comment Relation between statistical mechanics and quantum field theory
So in order to understand statistical mechanics I don't need any deep understanding in QFT (a basic course of many body should be fine). What about conformal field theory? Is it necessary? en.wikipedia.org/wiki/Conformal_field_theory

answered is there any difference between these Differential $dx^2$ and $(dx)^2$?
