comment The Center of Mass for proton-proton collisions at the LHC
Thanks, that was exactly the answer I was looking for.

@ACuriousMind different to a fixed target machine for one. Also, that proof does not lead to $4E_p^2$ can you elaborate on what you're talking about?

comment Does $R=\dfrac{4q^2}{\pi^2a^2gH^2}$ suggest a square root relationship?
Best answer, in my view.

@Gummybears do you know about cross products?

comment How is charge expressed?
@annav your answer may also answer this question but that does not make the questions themselves the same. This question is very specific and imho it is not asking the same thing that the question you linked to was asking.

comment Rotational mechanics - ball climbing a step
Do you understand what the question asks for when it asks for the "least horizontal force"? This is quite important to solving this problem. Once you know that you can just equate the lhs of torque with the rhs and rearrange to get your solution.

comment How is charge expressed?
@annav this is a very specific question about the frequency of the emitted photon.

You need an angle so you want to equate it to a torque expression with an angle.

comment Why do some objects tend to change their axis of rotation while rotating?
I will try to elaborate on my answer :-)

comment Why do some objects tend to change their axis of rotation while rotating?
Yes, because the pear itself is not spatially symmetric

@aShyGuy +1 if you can integrate these comments you have made into the answer itself.:-)

@kinokijuf agreed a little but definately worth all of my +1 for the presentation alone.

comment How do the Einstein's differential equation of the curvature of spacetime come out of Einstein's field equation?
@Dimension10 I don't think it's deserving of a downvote either but a and b could just as easily be subscript and g R and T have not been declared so they could also be anything at all, really. It is better to write things out explicitly so that equations have meaning and the answer is more complete.

comment Why isn't temperature measured in units of energy?
I saw ;-) I do also see what you mean now about the degrees of freedom bit now. I think I misused the word depend there. I'll change it.

comment Why isn't temperature measured in units of energy?
@Dilaton I don't think energy and temperature are the same thing. This is what I am saying with the derivation. It is a bit of an aside but essentially it should just to show that temperature has a dimension of its own.

comment In the Lennard-Jones potential, why does the attractive part (dispersion) have an $r^{-6}$ dependence?
Good effort but I noticed you've introduced some notations and not really made a full statement about what they are. Could you fix it? Also why is you arrow like that over both the $\vec{O_1 O_2}$ expressions?

How about making an attempt and showing people where you are stuck? It is much easier to help you if you do this. :-)
