I have a lot of sympathy with your position and I will generally put some effort into trying to interpret questions that are awkwardly phrased. However I think it's reasonable to expect someone asking a question to put as much effort into researching and writing it as they expect us to put in to answering it. As much can be learned from posting a carefully ...

Demanding that questions only deal with situations that unequivocally can occur in the real world rules out objects on infinite planes, point masses, Einsteinian trains, Maxwell's demon, supersymmetry, superstring theory, and any of the other standard thought experiments that form the underpinnings of a standard physics education. The ability of applying ...

Generally speaking, mathematical physics questions are on-topic and more than welcome. Note that advanced questions naturally tend to have fewer views, upvotes, and potential answerers. But don't get discouraged by that. You'll just have to be patient. If Phys.SE currently don't have the expertise to answer them, we might get it in the future! Also it is a ...

I think this question should be on-topic. To the extent that it is a software-recommendations question, it's precisely the kind of recommendation question we want to encourage: it is well-researched, it has a clear statement of goals and of the OP's situation, and clear requirements on the answers, which also make it clear that the answers are expected to be ...

Your question does not ask a conceptual question about physics, it simply asks users to solve the exercise you call "the Devil's problem". That you ask us to solve the exercise not by saying "Solve this for me" but by asking whether a given number is the answer doesn't change anything in my eyes - how is an answer supposed to make the ...

While I do not speak on behalf of the other close voters, the facts are clear: If the velocity is constant, the acceleration is zero. If a quantity is constant, it does not depend on time (in this context). Zero is clearly a constant, and a constant can be zero. Therefore, constant acceleration comprises two cases: Uniformly-changing velocity, which means ...

Deleting the questions will make it worse. One or two bad posts will not cause you to be blocked from using the site. Completely correct, you are not yet blocked. The exact algorithm is secret, but from what I see one more bad question won't affect you. The warning is more of a way to provide you with the links to improve your subsequent questions, the ...

First, note that not all homework related questions are off topic here. However... I wasn't interested in learning or understanding any physics methods; my interest was to find out whether 13 is indeed the answer for the problem in question. It's the Devil's dozen that made me interested. For me, the value of the posted solutions is that they prove that 13 ...

But, surely there should be a way for answers to be allowed for questions that get closed? Oh goodness no. That defeats the entire point of putting questions on hold (a.k.a. closing). Actually, there is a way, of sorts: edit the question to make it good, and then it gets taken off hold (reopened). That's exactly what we want to happen, in most cases. Or ...

With the remodeling of the review queues, users now have the option to explicitly mark their edits to closed questions as significant enough to warrant reopen reviews. So, as long as the editors refrain from marking their cosmetic edits as significant, there is no longer any reason to refrain from such edits.

I'm going to start by commenting the word "appropriate" in the context of getting downvotes. People sometimes seem to come to meta looking for a ruling that the crowd was wrong, but that is not how it works. We rely on the crowd to get things right. Votes (up and down) are plenary: excepting vote fraud people are empowered to vote any way they like. Nor ...

The most-upvoted answer to that question is a great example of discussing mathematics as opposed to doing mathematics. The meat of the answer is [T]he real problem is not so much nonrenormalizability as high-energy behavior inconsistent with local quantum field theory. ... With gravity, this high-energy/short-distance correspondence breaks down. ... This ...

A question of the form What is the biggest X? presumably means that an answerer should only answer if they are 100% sure that they know the unique answer (which btw may change in the future), and all other answers should be deleted. Of course that's not going to happen, so such questions in practice degenerate into What are examples of big Xs? For the latter,...

I for one think the question is unclear or too broad. “Inhabitable” is not really defined, and actually hard to define. One can imagine the surface of the Earth is cold but that doesn’t make it uninhabitable: some animals may thrive. The physics side is also vague. You do not specify anything about the black hole or its orbital parameter, so there is ...

In case you are talking about this question, it has been reopened by regular reopen review around the same time you posted this question. This site does not work in real-time and after I closed your question I had no further interaction with it, i.e. I neither actively refused to reopen it nor did I reopen it. Note that the first version I unilaterally ...

Physics.SE is for questions about physics. Physics means observations of the way nature behaves , note: observations. This rumble thing you are obsessing about is not an observation. It is a figment from the imagination of the author you have quoted. Physics.SE is not about interpreting dreams or visualizations or fairy land propositions or .... You ...

I want to point out one aspect of the question closure procedure which is relevant here but is not apparent to <3k users (and even then takes a while to realize). When voting to close a question, one gets to choose between the multiple options, but after you have five close votes the question gets closed regardless of what the mix of options is. (That is, ...

The following three points combine to contradict your thesis: The number of questions asked per week has been steadily increasing for the entire duration of PSE's existence. The number of users joining this site has grown rapidly the last year, but increasing always as well The number of questions closed per week has remained fairly steady over the last ...

Questions which are edited are put into a queue to be reviewed for reopening. This is the primary mechanism by which questions get reopened after being put on hold. Flagging for moderator attention is a backup option, to be used when the review process isn't working - either because the question is too old to be reviewed, or, if you really believe that the ...

This is not the first time someone has asked why simple physics questions are given less focus and/or ignored compared to more advanced material nor will this be the last. I will answer in the same way past and future incarnations of this question were and will be answered. This is not the case. Simply look at our most popular or highest voted posts or our ...

The SE will block your account from posting new questions if your existing questions are judged to be low quality, but the exact criteria they use have never been disclosed - presumably to stop people from gaming the system. I have read your existing questions, and you are obviously enthusiastic about physics. Can I suggest you ask in the Physics Stack ...

Let's kick things off with the most important one - the homework close reason, which currently reads Homework-like questions and check-my-work questions are considered off-topic here, particularly when asking about specific computations instead of underlying physics concepts. Homework questions can be on-topic when they are useful to a broader audience. If ...

I'm a bit surprised this got closed as unclear. It's really a duplicate and could have been closed on that basis, though I chose to answer the question because I judged it wanted a less technical answer than the duplicate. Anyhow I have edited the question in an attempt to make it clearer what is being asked. Jay, please feel free to undo my change if you ...

I voted to close this question for several reasons. It was extremely unclear when it was posted. I asked you to make several clarifications, after which it was still unclear. After more requests from clarification from two separate users, and seven revisions in total, it finally made sense. But most close votes had been cast before then. All four of your ...
