comment Any new texts directly on second law of thermodynamics?
have a look at books by Georgy Lebon, David Jou, José Casas Vázquez. There are several, several editions, get the one you can. Actually I don't see how is the question duplicates the linked one.

comment Maximum Principle vs. Minimum Principle in Non-equilibrium Thermodynamics
@Nathaniel, concerning MaxEnP, do you actually mean that the description of the system should admit non-unique solutions under a given boundary conditions? That is one defines what he means by "state" and then postulate that it is not determined by the environment and the previous state?

for those who might be intersted, the second paragraph seems to be about tippie top en.wikipedia.org/wiki/Tippe_top

comment Disregarding drag force that affects pop-up lightweight ball
what is the motion of the ball? Does it somehow create lift force or moves with acceleration? In either of this two cases there will be drag.

comment What's wrong with this reactionless drive?
your broomstick will also revolve with relativistic speed due to momentum conservation and become heavier.

comment Lennard Jones liquid vapour phase transition
@Sheng Sorry, I'm already moving beyond my expertise, I've never been deep in molecular simulation of fluids, just some basic things and I have never studied phase transitions, that seems to be quite and area. You should really study the state of the art on the subject and ask someone who knows better. Is that your diploma? If yes try to consult with your science advisor. But things are not so bad --- I'd say you have to just double your knowledge in the area (just double, no more) to be able to do it. Do you have all the books you need?

comment Entropy and the principle of least action
Concerning the second point --- how to you derive the form of $\mathcal L$? Shouldn't you here effectively postulate Hamiltonian mechanics?
