comment Calculating V1,V2,V3 in these equations
Hi Osama, and welcome to Physics Stack Exchange! Right now it's really not clear what trouble you're having solving the equations. It's a straightforward linear system. If you don't know how to solve simultaneous linear equations, that would be something to ask on Mathematics (or check a textbook, class notes, or some other resource). If you're having some more sophisticated problem, could you edit the question to clarify what it is?

comment Is there a quantity measured in kilogram seconds?
I'm not saying you're wrong, but changing $\Delta E$ to $\Delta m$ in the uncertainty principle feels rather contrived, at least. Of course one has to come up with something contrived to get a quantity with units of $\text{kg s}$, but I think it's more enlightening just to say there are really no common quantities with those units.

comment Can a human size object move so fast that it ceases to be observable?
@Schlomo feel free to ask on Physics Meta if you want to get a more direct sense of the community's opinion, but there seems to be very little support for the idea that this question is off topic here. It connects to physics because one might wonder whether an object's motion reduces the light that it reflects, and the answers establish that this is not the case. Whether it's possible that the light from a moving object could fail to trigger a visual response in an eye is indeed a matter for perception science and would probably make a good followup question on Cognitive Sciences or Biology.

I've deleted some comments that were off topic and/or obsolete.

comment Why do we fall down when the bicycle slows down?
@bobie let me suggest grouping up your edits, if you continue to make more, so that you're not editing the post quite so many separate times.

comment Is the Standard Model consistent (UV complete)?
I deleted an inappropriate comment and its responses. To the affected commenters: feel free to start the discussion over, keeping in mind our rules on civility, but you might want to do so in Physics Chat or another chat room in case it becomes extended.

comment Why is the range for a particle thrown at 90 degree same as that of a particle thrown at 0 degree?
The original question has been automatically deleted, so I'm unmarking this as a duplicate. But for future reference, it should have been an edit to the original.

comment How does the gravity well change as space expands?
I've moved the discussion that followed those comments to chat.

comment Explanation for this type of (magic-trick) suspension?
I would add that the mere fact that a question asks for a physical explanation of something does not, in my view, make it on topic here. I don't know that we have any explicit policy on that matter though. Perhaps it would be a good thing to discuss in Physics Chat or on Physics Meta.

comment Explanation for this type of (magic-trick) suspension?
@NikosM. no, this is not a serious issue because upvotes don't determine whether a question is on topic. Questions are on or off topic regardless of how many people upvote them. Indeed, historically off-topic questions tend to be some of the highest voted ones. Also, not that this is particularly relevant, but keep in mind that the number of people with the ability to vote on the question is more than two orders of magnitude more than those with the ability to cast close votes. (Also I've removed the unnecessary emphasis from your comments.)

@ACuriousMind true, though I've now edited that part out.

I've deleted a few inappropriate comments and responses, and moved the rest to chat if you would like to continue the discussion.

comment If a theory of everything exists, is it necessarily unique?
It looks like the comments here were turning into an extended discussion, so I've moved them to chat. (Brand new moderator power!)

comment The Gluon - Does It Exhibit Wave Properties?
Well... virtuality is an inexact art, but basically because gluons are confined, they have more "freedom" to be virtual than other particles.

I deleted some inappropriate comments and the associated discussion. Please remember that civility is expected at all times on this site; this is an official warning that rudeness will not be tolerated.

comment “A Crash Course in Lagrangian Dynamics”. Is it still available online?
@AppliedImagination OK, but I think this policy applies anyway. It covers all questions where you are trying to find the content of the reference, not just those where the reference is paywalled. (To be clear, I'm arguing that based on the meta post I linked, this question is actually on topic here.)

FYI @Danu and others the relevant policy is here
