comment Entropy and the principle of least action
Technically everything seems to be correct and indeed answers half of the OP's question.

comment Could the Bernoulli effect be causing my ceiling to come down?
Stick with your last formulation --- aerodynamic forces are indeed likely to cause such a behavior.

comment Is there really time reversibility in physics?
Does CPT symmetry implies reversible behavior only on a flat spacetime or taking into general relativity provides irreversibility?

comment Lennard Jones liquid vapour phase transition
In addition, specify your cell and boundary conditions, potential truncation method, what is the average cell size corresponding to you preassure. Why don't you also just post your "density versus temperature graph"? Apperantly it's your own programm, am I right?

comment super-jump air balloon
Haven't you forgot added mass? en.wikipedia.org/wiki/Added_mass Though I'm too lazy even to estimate how important it is for the case.

comment Parameter determining argon phase
@Sheng be sure to look attentivly at the phase diagram to see where the supercritical fluid rests, look at phase diagrams in the Wikipedia and SklogWiki. Phase diagramm is 2D and "above a point" is not a good definition of a place on a 2D plane. Personally I remember studing phase diagrams several times (in various coodrdinates) and each time I discovered something new. Yes, that may sound stupid --- how such a simple thing as a phase diagram may suprise you. And once I didn't know about supercritical fluid either, though I was told about it, I just missed it somehow.

comment Parameter determining argon phase
What's your N? By the way "some states which should be in vapor form" --- why do you think they should be in a vapor form?

comment How does a vacuum oven work?
doesn't reducing :heat loss which is caused by convection" contradict "quick cooling of the product as there are no air to hold heat around product"?

comment Intuitive explanation of the inverse square power $\frac{1}{r^2}$ in Newton's law of gravity
What do you think is more flawed --- transition from points to surfaces or from the force between two bodies to a field?

comment Intuitive explanation of the inverse square power $\frac{1}{r^2}$ in Newton's law of gravity
Why is proceeding from point-like bodies to surfaces is "too speculative"? At least in the framework of classical physics. Though, frankly speaking, I see no explanation for the square power in classics, being it geometrical or not. Nevertheless if there some general principal prohibiting transition from points to surfaces, I'd like to know it.

comment Interesting Math Topics Useful for Physics
"interesting, but less popular" The specific math topic is either required or not. As for your question, for a start you should know algebra and differential geometry, that's the basic requirement for every field in physics.

comment Why quantum mechanics?
As for me it's physics, you do not motivate studying the theory, you motivate studying certain kinds of phenomena/objects/processes. You just say that this and this cannot be treated in classics. Personally, I was never interested in the scope of quantum mechanics, I just don't care what happens in the microworld, knowing the difficulties in describing macroscopic phenomena, say like turbulence. The only thing QM served for me is advancing my math.
