comment Simplest example of spontaneous breaking of time reversal symmetry
Practically they all are the same problem that you proposed, however they should be mathematically simpler than the original set of hydrodynamic equations.

comment Simplest example of spontaneous breaking of time reversal symmetry
I would suggest to have a look at this two papers iopscience.iop.org/0305-4470/17/12/025 link.springer.com/article/10.1140%2Fepjp%2Fi2014-14190-3 They refer to a truncated spectral decomposition of a 2D convective fluid equations.The authors end up studying a gradient type system, of which stable points represents clockwise and counterclockwise convection. Also in the following paper (in particular the reduction of the Lorenz equations to the system 2.16) iopscience.iop.org/0038-5670/21/5/R07

Ok no prob :-)! I was not sure where to post this, so I read the description of the tags I used but it seems I have understood them too widely.

I programmed Excel cells for binning in the aforementioned way and now I wanted to check what I did somehow. I guess not even Origin 9 can do what I described (but it's strange because is something which should be really common)

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
