YES Physics.SE should undergo a 30 day test with 3 votes required to close and reopen questions.

I agree and would vote to reopen if the closing vote weren't a mod. Reasons: One does not know before asking the question what the answer is going to look like. Once you've seen the answer then one could say it's a meteorological phenomenon and not a physics one, but a priori it could equally be an optics question. Meteorology is intimately related to ...

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 ...

Closing questions is not an expression of disdain. It's merely saying that a question like this is not suitable for the site as it is today, in this instance because it is not inside the scope of physics as a natural science. When the scope of a site changes, which inevitably happens over the course of the years (and in particular we are today simply ...

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 ...

Yeah, I think that makes sense. The question in its current form seems like just the kind of thing the new recommendation policy is designed to encourage, and we should definitely have one open question about intro QM books. (Of course we also have to make sure the answers are in shape, but that can happen whenever.) Since this is an active meta discussion ...

Ah Dec. 2019... those were simpler times eh? So what happened was by Jan. 2020 we were on the list and working to get a more complete dataset defined to extract, and the Community Manager (CM) who was going to write the scripts to do that analysis was let go from the company. So that kind of set things back on getting any sort of custom data defined. Then ...

The title of the question is "Find the Thevenin's Voltage," and the first line is "Please solve this." In its current form, it is a straightforward homework question. If there is a deeper, on-topic question contained inside, then the question should be edited to contain only that question.

Since my motives are being questioned, let me add this. I voted to close this question because I didn't think it was about physics as defined in the scope of this site. That's all. I don't see that the age of the post (which I didn't notice) makes any difference. Perhaps the criteria have changed in the 10 years since this question was asked? There isn't any ...

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 ...

The close reason on the question directs to the help center. The first bullet point in the on-topic section reads: Explanations of observed physical or astronomical phenomena Perhaps there is confusion since the question is asking "what is this" rather than "why is this". Unfortunately, to effectively do research for "why", ...

I agree with you: while most questions about engineering are off-topic for us, we make an exception for engineering-like questions about experimental apparatus. I've retagged and reopened the question.

This is a question that would help with the understanding of specific heat and conductivity and which has a greater effect when it comes to transfer of energy between objects. If the question is about that, then it should be clear that this is what it's about. In other words, the question could be something like: "How do the thermal conductivity and ...

Based on some of the comments (now deleted), it looks like the first user who voted to close did so because they were focusing on how the OP was trying to apply scaling space to Newton's second law. Perhaps the first user figured that the OP was talking about their own theory of scaling space then? Although in my (speculative) opinion, this user seemed upset ...

You're asking for a list of theories, which is a question without the potential of having a "correct" answer and is usually seen as too broad around here. See e.g. Good list, bad list and its linked questions for prior meta discussion of questions asking for lists

I do agree that it's not really a duplicate; but it should remain closed. For one thing, it's hard to understand the question behind the huge rant. Your rant seems to entirely focus on how unclear some people are when they discuss the "number of atoms in the universe". From what I've understood, you seem to have an issue with how some people choose to ...

I did imply in my question that I wanted to see a solution, but that was merely because I wanted to verify. I wanted to get convinced whether 13 is the answer. We call these check-my-work questions. Yours is exceptionally interesting, and perhaps the community will vote to reopen it on that merit. But generally check-my-work questions are not high-quality, ...

Even though you have eliminated an explicit reference to opinion, this does not change the fact that IMO the question is still opinion-based. I can answer yes/no/I think so/I don’t think so without reference to any physical law or principle, and my answer would be just as good as anybody else’s.

Someone (I don't know who it is) has been going back through old questions and voting to close old questions that don't meet our current guidelines. While I admire the commitment involved I'm not sure it helps the site that much. Anyhow, I suspect your question received a close vote as part of this activity, and once a question has received one close vote it ...

I don't support reopening this question (currently, revision 3) because I think it has a couple of issues that justify it being put on hold: First, as enumaris brought up in the comments, This will depend a lot on the mass of the black hole and how close the approach is. There's no way to answer this question without further parameters. Basically, there ...

To be honest, I don't think you reacted particularly well there. The two questions are very similar, and they deal with much the same subject matter. Generally, when a question is marked as a possible duplicate, we ask that the OP of the new version make more explicit which aspects of the new question are new; this helps keep answers on topic and reduce ...

This should be an easy answer. Yes. We should trial this. Stack Overflow tried it and were really happy with the results. And that's just what it is, a "trial". Rather than speculating on what the ups or downs of this could be, we have the opportunity to experimentally determine the true situation. If it doesn't work well, we don't adopt it permanently. If ...

I agree that it's not really a homework question, though pasting a screenshot of the problem they're working on certainly looks like our everyday HW problem, but as you stated, Possibly it could be closed as being unclear, because the problem itself is not sufficiently defined. But this can be easily rectified. OP requested an explanation but didn't ...

I have a degree of sympathy for your position, and had I seen the question before it was closed I would have posted an answer. But my answer would be that you have misunderstood what we mean by the term photon. Have a look at my answer to Do photons truly exist in a physical sense or are they just a useful concept like $i = \sqrt{-1}$? Photons are only a ...

As the banner at the top says, that question was closed because a similar question, Is spacetime absolute?, was already asked and already had satisfactory answers. Note that our community is based on asking questions and getting answers, not on having discussions. If you post exactly the same question again, the community will probably vote to close it as ...

Y'all may have seen the update I wrote as it was linked in the comments but I wanted to give y'all a specific update because the use case y'all have for this is very different from our goals of the test. Our focus is on doing two things: Increasing the percentage of review tasks that are completed. Reducing the percentage of review tasks that are completed ...

As one of the close-voters, I guess I should speak up: I did not vote to close this question as a duplicate; instead, I voted to close as being primarily opinion-based and therefore not answerable in objective, scientific terms. In those terms, I would say that the existing closure as a duplicate is a less strict response (in that it sends you to other ...

I think the question is now perfectly acceptable, and I personally would vote to reopen it. That being said, it's not very good for the community moderation model if I go around closing and opening things willy-nilly. Your question was reviewed twice since you edited it (first review, second review, and all four reviewers thought it was still inappropriate ...

From the help center: Questions can go through multiple close and reopen cycles, but each individual user may cast at most one close and one reopen vote per question. A restriction like this makes it harder for a small group of persistent voters to override the community's intent on a controversial question, by persistently re-opening a bad question or ...

(For version 1)You have two explicit questions. The first is in the title: "Is it an illusion if reheated tea burns my tongue but tastes cold?". The second is at the very end: "why should there be a difference in how well the oil-like substance is "mixed"?" It seems like the post is asking about both of these at the same time ...
