comment What does Peter Parkers formula represent?
And on one side some thermo eqns. And the oxidation of glucose. The unboxed stuff is probably just random stuff they picked up from here and there.

Its most probably something to do with probability.

The text around the box suggests biology(cytokine, cells, etc), but that may be unrelated to the boxed content..

comment How does compression of carbon atoms work?
One thing: graphite is anisotropic, so all properties depend upon orientation. Compressing it in one direction Is relatively easy as compared to another.

comment Do Maxwell's Equations overdetermine the electric and magnetic fields?
You can write in TeX by enclosing the texcode with dollar signs (inline), or double dollars.

comment How equivalent are heat energy and work energy in connection with a spinning flywheel?
I think he's saying that he is giving the flywheel a $v_cm$, thus increasing its energy. As energy $\propto$ mass, the mass has increased, and thus the moment of inertia has increased. So $\omega$ decreases. That's the OP's logic (I think) The main issue here is, how does one deal with rotational kinetic energy in relativity? I'm not too sure of this, so I'm not answering this one.

comment Book for learning about constructing correct physical modeling
Theres not enough data to solve it fully (I am assuming that $c_1$ etc are natural lengths). The system will rotate in a complex manner, but to analyse this, one needs the dimensions of the block $m_1$ and the upper frame. Or we can neglect rotation and then the problem becomes trivial. Oh, and what do you want to calculate: frequency of oscillations, or equilibrium position?

comment How much energy was consumed when we turn on/off light?
@ZoZo12343 the 15 secs was a play on the asker's 15 minutes. I have no clue how much it is, but it certainly is less than 15 minutes (the values of inductance and resistance are too small). Like I said, it could be 15$\mu s$ also. :D Above, DavidZaslavsky has given 20s as t he value obtained by MythBusters.

comment What forms are theoretically predicted for orbitals or quarks in hadrons and of hadrons in tritium?
@annav Would it really be spherically deformed ? I havent seen that paper yet, but it makes morse sense if it was a complicated, but rotationally symmetric field. Of course, visualising the slew of interactions is pretty hard.. So maybe it may be asymmetric. I'll check out the pdf later. Thanks!

comment Book for learning about constructing correct physical modeling
Yes, I know, I was looking for an example of a moderately complex system, as I still havent understood your confusion (You seem to know how to make FBDs). If you give a moderately complex system, and explain your confusion, then I could show you how to do the analysis.

Thanks, that helped too..

comment What forms are theoretically predicted for orbitals or quarks in hadrons and of hadrons in tritium?
Quarks in a hadron don't need orbitals, as they have different quantum numbers (the color number). So they can occupy the same wavefunction/orbital (just like two electrons in a single orbital who have $m_s=\pm\frac{1}{2}$), and the orbital will probably be a very (probabalistically) dense spherical body.

comment Book for learning about constructing correct physical modeling
@maximus Could you describe the system? With a diagram possibly? Even if the apring vibrates, force wil be in one of two antiparallel directions, and it will switch between these every time period.

comment Book for learning about constructing correct physical modeling
Do you know how to construct free body diagrams? enwp.org/Free_body_diagram . Spring forces are always along the length of the spring, though there are a few shortcuts that you can use when dealing with multiple springs (series-parallel combinations of springs, generalizable to springs at angles)

comment Why is introductory physics not taught in a more “axiomatic” way?
Also, if physics is taught that way in its introductory phase (middle and high school, nobody will like it and thus they won't understand it at all. Intuition is essential to develop a new topic..

comment Why is introductory physics not taught in a more “axiomatic” way?
Another issue is that axioms can be switched around. For example, inear and angular momentum. One can prove one from the other.. So, there are no fundamental axioms of physics, just a large set of axiom multiplets of which you can choose any multiplet.

comment Will a warm body naturally slowdown?
Now you tell me... After I typed the whole thing on a phone :P. Anyways, there's one more thing in that answer which you may have been neglecting (though it will only be required if you're trying to actually prove this quantitatively). Basically you neglected the relativistic doppler effect, too (see above answer).

comment Will a warm body naturally slowdown?
The momentum carried by radiation is a quantum mechanical effect, not a relativistic effect. But you're right, we cannot neglect relativity. I'm posting it as an answer (will take 10 mins, not doing this from a pc), as its a bit long.
