comment Navier-Stokes equations through a orifice
Chapter III Turbulance models may help you, but as fellow commenters have suggested, it is a tough problem to crack. See waset.org/publications/4244/…

comment Is there any relationship between the $E=mc^2$ equation and the $a_n=\kappa v^2$ formula for the normal component to acceleration?
Just to nipick a little, I would argue that your example of the area of a circle should be written $\iint_{x^{2}+y^{2}\leq r}1.dxdy$ then calculate the integral using polar coordinates $\int^{2 \pi}_{0}\int_{0}^{r}r dr d\theta = \int^{r}_{0}2 \pi r dr=\pi r^{2}$

comment Temperature as the independent variable of Lagrangian
Sure, I recently read arxiv.org/pdf/1110.6152v1.pdf as an introduction.

comment What's the degree of freedom of this kind of matrix?
Is there a typo in your second summation over $k$? Should it not be $\sum_{k}a_{ik}$?

comment Temperature as the independent variable of Lagrangian
There is indeed a significant amount of work in presenting a Lagrangian formulation of Thermodynamics due to the fact that both temperature and an entropy may be associated with horizons in semi-classical general relativity.

comment BRST quantization of point particle
$Q$ is an anti-derivation see here en.wikipedia.org/wiki/Antiderivation#Graded_derivations also $Qc = \frac{i}{2}[c,c]$

comment Spacetime, space observables and time observables
For exposure to how much attention is actually given to the nature of space-time as a geometric structure (i.e., manifolds equipped with non-degenerate metrics) see Hawking and Eliis' the Large Scale Structure of Space-Time.

comment Is the orbit in Schwarzshild metric a path with maximal proper time?
Very good question; may I refer you to the following posted question. I think you may take something from the answer. physics.stackexchange.com/questions/18781/…

comment Is there a scientific term for star formation?
I really think that as an unbrella term for the entire subject discipline; Star Formation is widely used and accepted as the term of choice.
