comment Thermodynamics and cross entropy
Sorry, but I don't understand. You are telling me that if I put a system of T1 in contact with a bath of T2 the work I can extract is different from putting a system of T2 in contact with a bath of T1?

comment Thermodynamics and cross entropy
I have a doubt. If Dkl represents the maximum work we can extract from two thermodynamic bath, why it is not symmetric? Namely Dkl(Q|P)/=Dkl(P|Q).

comment Vacuum energy and perpetual motion
Thanx, anna but i know the problem of conserved quantity in curved spaces. In my opinion the question is actually more subtle, because in our universe we can define a universal time, indeed we can speak of the age of the universe.

Good answer, but lacking of one point. Why is relative humidity more imortant then absolute humidity in precipitacion levels?

comment Identifying a critical phenomena?
@RonMaimon first order transition are included because i say very clear "...mean or variance, of some physical quantity, are not finite" namely first and second order transition.

comment Funny recurrence in escape velocity calculation of some planets
i am sorry, i guessed that 1h is one hour in all the world. This question is not on the calculation of escape velocity, but in the strange feature of it so i quit the basic formula $\sqrt{2G M/r}$.
