comment Partial derivatives vs total derivatives in thermodynamics
@ChesterMiller that sounds like it should be an answer

comment How to (safely) measure the surface area of a human body?
Perhaps you could rephrase this not to mention discussion? After all, we don't want questions to be discussed, we want questions to be answered.

comment Path of a swinging object on a rope
It's a very sparse post, to be sure, but it doesn't seem so obviously not-an-answer as to be deleted.

comment Why is the Pythagorean Theorem used for error calculation?
I don't think it's off topic. Uncertainty in measurements seems like a part of physics to me. We've taken previous questions of this nature, such as this one.

comment Is any photon really moving?
(1) Comments aren't the place for answering the question (2) I don't think this is a duplicate of the one listed in the first comment because that is asking about time, whereas this is asking about space.

comment Finder scope on telescope
Worth noting that astronomy is within our scope, but I do agree that this particular question is off topic.

comment wind force necessary to move large garbage bag on ground--snow covered and grass
I'm voting to close this question as off-topic because it's a calculation request, not a conceptual physics question.

comment A gravity question
I don't like this answer because gravity is much more general than just how much something weighs on Earth.

comment How is father of physics appointed?
I'm voting to close this question as off-topic because it's not about physics.

comment Hilbert Schmidt inner product
@NorbertSchuch I'd say both. Obviously the best choice is to flag as a duplicate (which auto-generates a comment), but if the system doesn't let you do that, post a comment and cast a flag. Or, in this case, if the problem is merely that the other post doesn't have an upvoted answer, you could ask in chat for people to review your answer and upvote it if warranted, which would presumably then allow you to cast the flag.

@NorbertSchuch and yet you answered it anyway...

comment Time reversal $t\rightarrow -t$: $0,10,20,30,40,50$ to $-50,-40,-30,-20,-10,0$ or $0,-10,-20,-30,-40,-50\;?$
One question per post! The part you edited in (which I rolled back) would make a good separate followup question though, so I'd encourage you to post it separately. (Extra benefit: more free reputation)

comment Is there an equivalent of the Planck length for time?
Mikey, I made kind of a radical edit to your question because it seems like what you really want to know is whether there is something like the Planck length, but for time. We don't usually make such edits, but in this case I think it makes the question better and also makes the existing answers fit your question better. Please check it and if this doesn't reflect what you want to ask, change it so that it does. I took out all the stuff about "smallest unit of time" because that is an entirely separate matter from Planck units.

comment How do we know that light is made up of electric and magnetic fields?
@brightmagus indeed, I know that. It's impossible for a question to provide the answer, because it's a question, not an answer. ;-)

comment How do we know that light is made up of electric and magnetic fields?
It definitely is a duplicate. But I agree that the closure of the other question looks odd; we should probably review that.
