comment Is a causal relationship implied by Newton's 2nd Law?
This is a very useful comment (and a good ensuing discussion), but it doesn't appear to actually answer the question of whether a causal relationship is implied by Newton's second law.

comment How many wavefunctions are in a minimal basis set for benzene?
I think it might be on topic here, since it is about wavefunctions after all. We'll see what other people say.

comment Proving standing waves equation for open-open pattern
@yolo123 regardless of whether this is homework or not, the purpose of this site is not to help people with this kind of question. I explained why this is on hold in my previous comment, but for more information I'd encourage you to read our homework policy, and also I can clarify my reasons to you in Physics Chat.

comment Proving standing waves equation for open-open pattern
@soumyadeep as the post notice says, there are two requirements for a homework-like question not to be put on hold: it must ask about a specific physics concept and it must show reasonable effort on the part of the questioner. This question doesn't ask about a specific physics concept, which is why it's on hold. I would argue that just asking what to do next doesn't really show effort either.

comment What is the fluctuations of the energy of a simple harmonic oscillator?
No problem. For integrals, I'd suggest giving Wolfram Alpha a try (or Mathematica if you have access to it), and searching for websites that may show how to go through the same problem. If that doesn't yield anything, you could perhaps post a question at Mathematics; they have different guidelines about what is on topic there.

comment What is the fluctuations of the energy of a simple harmonic oscillator?
Hi slek120, and welcome to Physics Stack Exchange! This question doesn't seem to be asking about a physics concept; you're just asking for help doing an integral, which isn't what this site is for. If you edit your question to ask about the specific concept that's giving you trouble, it can be reopened (taken off hold).

comment Is there a reason why the spin of particles is integer or half integer instead of even and odd?
@DanielSank that could probably be an answer. (Of course there is also room for an answer that explains the history of $\hbar$ coming to be the unit of spin, but I think you can write a perfectly valid answer without getting into that.)

comment What technology can result from such expensive experiment as undertaken in CERN?
I moved the comment conversation on this question to chat. Go forth and discuss away :-) just not here.

comment Is it true that 3 different types of sound produces at different stages while boiling a water?
I'm going to mark this as a duplicate, because the answer to the linked question does seem to address it, although I could see a case for this being handled differently.

comment Why does this condition ensure that the residue of the propagator is 1?
I will note this was already answered elsewhere: reddit.com/r/Physics/comments/2gigu8/… (and by the way 0celo7, the fact that nearly the same text is posted here and there may constitute a violation of our plagiarism policy... I'll be looking into this)

comment Any good resources for Lagrangian and Hamiltonian Dynamics?
I'm adding the post notice because there's no reason not to, but I think this may be a duplicate of a question we already have, perhaps this one.

What have you looked at so far to try to find an answer?

@BrysonS. that should be an answer.

comment Can we add any two vectors?
In that case you could try Physics Chat or another chat room, but regardless, this is not the place. (And it's not deleted.)

comment Can we add any two vectors?
@user166748 for anything that concerns an answer to your earlier question, you should comment on that answer, not this one.

comment Can we add any two vectors?
@New_new_newbie true, but at the same time part of what we mean when we say this is an "expert-level" site is that we shouldn't feel obliged to refrain from giving advanced information when it's relevant. And in this case I think your answer oversimplifies the situation a bit too much - though not enough to be downvote-worthy or anything like that.

comment Can we add any two vectors?
While technically correct, I don't know that this is what anyone means when they talk about adding vectors (at least, 99% of the time, and almost surely not in this question).

comment Can we add any two vectors?
I wouldn't say it's the only sacred tenet. A somewhat subtle lesson to take from GR is that tangent vectors at different points on a manifold can't be directly added (or subtracted). That's an instance of the more general point that you can only add vectors which belong to the same vector space - although one could argue that's circular reasoning since being addable is part of the definition of a vector space; still, the point is there are reasons for it not to work other than a unit mismatch.

comment Understanding the Particle Data Group review documents
I would agree that requests for a full explanation of what each piece of information actually means should be split up into separate questions. But I actually think a high-level overview, at the level of just saying "this is parity, this is angular momentum, these are the decay modes" and so on, could constitute a single question, and it would be a useful question to have because I bet a lot of people who are just entering the field ask the same thing. Of course, the answer you'd get may or may not be particularly useful to you, Lance, but you could do your own research from there.

comment How do objects even move due to gravity?
As the ensuing comment discussion has moved to chat I've removed it from here.
