and then it is hard to tell if the curve is starting to increase again or stabilizing around a constant value of 7%. I don't think this is hard. It's pretty obvious to me that the duplicate closure rate has saturated at a value of about 7%. This is vaguely high for SE standards but not something I'd be at all inclined to worry about. Here is a copy of the ...

No, you have done the right thing. With some many questions on the site it's very easy to miss the fact that a duplicate exists, and to be fair the site search isn't as great as it could be. Don't attach too much significance to the downvotes. It's easy to feel that downvotes are a personal criticism, but really they are just a statement that the question ...

There are a few ways: If you have >3k rep, you can directly vote to reopen. This will put the question in the reopen review queue. Once in the reopen review queue, users with >3k rep can vote to reopen. If five users vote to reopen (either through the queue or directly) the question gets reopened. If the question receives enough Leave Closed votes (which I ...

I suggest paying attention to, and reading some of the suggested questions that pop up when you start to ask yours (I know this feature exists on the desktop site, maybe not mobile). This is an example from when I type in a new question with the same title as your question from today; which is gaining some votes as a duplicate. I actually flagged this one ...

As long as there are new inventions and new discoveries, there will be new questions. For the network as a whole: find your favorite programming language that is less than ten years old, and search for questions about it on Stack Overflow. Or on Area 51. For physics in particular: consider the timely questions about the OPERA superluminal neutrino non-...

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 ...

While there is some overlap, I wouldn't call it a 'wall of text' (which has generally negative connotations). Nor is it particularly 'bottish'. The user appears to be legitimately answering a variety of fundamentally similar questions, which require a fundamentally similar answer. Perhaps your complaint should be why most of those questions have not been ...

If a merge is not in order (and I don't think that one is), then re-using your own material is reasonable and proper. I hesitate to suggest verbatim coping of an answer, because most of the time we treat that as a sign of possible abuse. Does posting a substantially similar answer that has refocused for the slightly different emphasis of the two question ...

I have no objection to the proposal so I'm not going to vote it down, however I'm not sure how well this is going to work in practice. If you take the Q/A of mine that you link, I wrote this mainly for personal reasons. I had finally got around to working though the analysis of acceleration in Chapter 6 of Gravitation and was feeling really proud that I'd ...

Before asking a question: Use the built-in search engine to search for duplicates. Alternatively, search the Phys.SE site with an external search engine, e.g. Google. When asking a question: Pick a good title which captures your question in one line, preferable in the form of a question. The SE software will then suggest possible duplicates. Fill in ...

We do have a procedure in place where users of the site can vote to reopen closed questions, and I see that your question currently has one reopen vote. The best way for you to speed this process along is for you to edit your question with some text like "it's been suggested that this question is a duplicate of [link]. But that's a question about X, while I'...

There are several competing desires for how to close (and possibly merge) duplicates (listed in my preferred order, but that shouldn't be taken to represent official policy): Priority to the best question. Priority to the oldest question. Priority to the most popular question (As indicated by views or by votes or by number of non-trivial answers.) Actual ...

It depends on what the question is about. I sometimes have to make this choice, because I'm reasonably active on both sites. There's a substantial amount of temptation to go where the user base is. There are, without question, more astronomers and astrophysicists studying at an advanced/professional level and actively answering questions on Physics Stack ...

Changed the title from Balance of a spinning coin to Balance of a rolling coin, and reopened question.

One other thought is that, if it's essentially the same question as one already posted & answered but at a higher level than what you want, then you can always offer a bounty on the question with the specific request of a lower level answer.

The mere fact that you read something strange does not qualify it as a physics question. People can write anything they like, and no one and nothing stops them from writing unphysical nonsense. In fact, some of us read unphysical nonsense for entertainment, so we pay them to write unphysical nonsense. We do not feel obligated to answer question about such ...

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 ...

Much of the data is public, over at Stack Exchange Data Explorer, so you can go and do some number-crunching yourself. Some of the data is available only to mods, and some is available to >25k rep users, and it shows no such decline. Over the period since January 2015, we have There are some seasonal variations (such as the obvious dips over the Christmas ...

Premise: two posts asking the same question are not, by default, duplicates if they are both explicit about the desired level of sophistication, and they are significantly different levels. Let us be more precise about what we mean by the italicised words: Explicit: the level of the question must be clear in the question itself, not by adding a "I know ...

I think linking to a question you have answered yourself is a perfectly reasonable thing to do. I regularly do this myself and have written several self answered questions specifically to provide a canonical question and answer that can be used as a standard reference. I understand your squeamishness - I feel much the same and sometimes (not always!) make ...

Important note: whether two questions are duplicates depends on the questions, not the answers. The first question, which is currently marked as a duplicate of the other, asks Why don't metals glow from red to yellow to green to blue etc.? Why only red, then yellow and then white? Shouldn't all wavelengths be emitted one by one as the temperature of the ...

No one except you can see that banner, so it will not "deter potential answerers". It is a message designed to streamline the duplicate close vote procedure, and give askers the opportunity to shorten the process if they agree with the vote, and force them to make their question more precise if they don't. Your edit is not supposed to become an explicit ...

If the new question you would ask is similar enough to the old question that the same answer (verbatim) would apply to it, it would probably be a duplicate. So I would say no, don't make a new question for the express purpose of reposting your answer. The information in your answer already exists on the site, there's no reason to invent an excuse to put up ...

My two cents: You should search for duplicates before asking your question, but the built-in search engine is really not that good for this task. Doing a google search for your question with "site:physics.stackexchange.com" at the end of your query is a superior way to find duplicates on this site. Compare, for instance, my search for duplicates to this ...

Shouldn't the second be marked as a duplicate? In this specific case, the first question (together with its answers) is noticeably less clear and useful than the second one, and indeed it covers a strict subset of the latter. How would it help the site to close the second one as a duplicate of the first one? On the other hand, I am bothered by the fact ...

This is a feature added since 2014: Increase close vote weight for gold tag badge holders. To put it simply, users can now unilaterally close a question as a duplicate if they have at least a gold badge on one of the tags. For this specific case, you have a gold badge on 'general-relativity' tag and closing a question tagged with it.

Cross-posting questions is frowned upon. If you've managed to do so, the least you could do would be to include links connecting the corresponding questions, to save your readers the trouble or confusion of figuring out by accident what's happened. It's enough to add a comment like "Cross-posted to [other site]: [link]." It's polite to leave such a ...

Frankly, I would suggest that you should leave those old questions alone, and move on to newer questions $-$ it won't help very much to try and fix them, and the only thing you'll achieve is to get back into a deeper examination of questions which didn't do very well. You should certainly add links as comments under the Physics versions to any existing ...

Yes, you can. If you have that problem then there is a significant chance that others will in the future, and having a thread at that level will make the site a better resource overall. However, you need to be very careful to explain how your question is different from the previous iterations - in this case in terms of level. Carefully explain what you do ...

Exactly what the official SE line is I'm not sure, but I'm personnally not that fussed about duplicates. Apparent duplicates often stress different aspects of a problem, and I'm not sure it does any harm to have separate questions and answers with different perspectives on a problem. I've even occasionally flagged a question as a duplicate of a question that ...
