I've spent a lot of time on meta arguing against the closure of good mechanics problems (most recently here and here) and taking a lot of downvotes for it, but here we go again! As the homework policy seems to be currently understood, any mechanics problem that requires a specific calculation deserves to be closed. It doesn't matter if it's actually a ...

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 ...

From the help center: What should I do if no one answers my question? First, make sure you’ve asked a good question. To get better answers, you may need to put additional effort into your question. Edit your question to provide status and progress updates. Document your own continued efforts to answer your question. This will naturally bump your ...

Some of the reactions here are a bit more negative than they need to be, given that you're fairly new to the site, so a bit more explanation is in order. Tags are organizational concepts: they exist to classify and organize the questions that already exist on the site, and to make them easier to discover and link together. They are not magical beacons that ...

I'm inclined to agree with your original assessment -- this is not a good example of the kinds of questions we want. And, as a regular user, I would have voted to close it if I had seen it prior to the bounty (because then it is locked). And as a moderator, I would probably vote to close it if it got a couple of other users who voted to close it first. ...

I see a more global problem here. Regardless of whether this is an actual homework problem, and regardless of the putative small audience of interest, what are we to do about vetting the answers? I know this isn't a peer-reviewed journal. My concern is that upvotes on answers does not imply correctness. What's the value of potentially conflicting ...

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

I actually believe that forcing people to identify themselves when voting would simply lead to discord and acrimony. On balance the current system works quite well, and this particular community does not hesitate to reverse all kinds of closure/downvotes etc when a coherent argument that said closure etc was an overreaction. Some are thin-skinned users ...

To directly answer the question: Even if the question is acceptable, why are these answers acceptable? [...] But why does the fact that it has not been considered an off-topic homework question mean that posting full solutions is fine? They seem to be two separate policies. The bounty did call for actual solutions, so is it fine to go against usual ...

Since I've been commenting my thoughts, it seems fair I should post them as an answer. My answer was initially going to be a hard "yes" on close this as a homework question, but I'm becoming less sure. On the one hand, the people answering the question have put a lot of effort into trying to solve this problem, and clearly it's motivating people, and ...

There are a couple of different things that are happening here, and I'm not sure that I will quite disentangle them while I'm writing this answer, but here goes. First, there's the question of topicality. I've been on record nearly since I joined with the opinion that interesting questions deserve more leeway than boring questions, and that it's a ...

As of today, a search for 'aerogel' in Physics SE comes up with 15 total questions across the whole site. No, I don't think we need an 'aerogel' tag.

Let us look at the rules (http://physics.stackexchange.com/help/on-topic): "Some kinds of questions should not be asked here: "Do my homework"-type physics questions" So the rules use the words "should not", not "shall not" or "must not". In my book, this is not an absolute ban on such questions. In this particular case, many people liked the question, so ...
