I have upvoted, but still, one criticism of the answer is that you referred to an explicit basis when explaining ( cartesian). But otherwise, I think is certainly valuable.

I just read your answer to which you linked. It looks great to me, so I just upvoted it. Your answer is clear, informative, helpful, and easy to read. All are attributes of a quality answer. My only very minor recommendation is to be cautious about phrases like "if you are confused about this". Because tone is very hard to detect online, that ...

The familiarity of an OP with the terminology should not enter into anything. The broader objective of the site is not so much to provide answers to questions of individuals, but to provide answers that are useful beyond the OP to viewers at large. As a result, I make no accommodation for poor use of terminology in questions (or answers): since the ...

Looking at your reputation tab, this seems to be only the second downvote you’ve received after a year on the site. I’ll let other folks comment on the specifics of your answer (which also has an upvote). But I’ll offer this general advice: don’t worry very much about a single vote one way or the other. The more you write, the more you’ll be able to look for ...

In Q&A format, a thread which is a genuine attempt to share knowledge, but is actually wrong, can be given a better answer by others and the OP's wrong answer down voted. (I'm not talking about trolls or crackpots here - just honest errors). A "blog post" which doesn't clearly define what question it is asking or answering is harder to fix.

The questions here and here have comments that should have been posted as answers, and replies saying "thanks, please post this as an answer." You have proposed to delete the thank-you comments, which will permit the Roomba to cull the question. A better solution might be to transfer the should-have-been-an-answer comment to an answer, then mark ...

I was the moderator that rejected most of your flags. There were 4 or 5 flags from the same user in a very short span of time, on questions from 10 (or something) years ago. While the intentions you are now describing are noble, as per the Roomba definition: the annoyance to those searching for a solution outweighs the increasingly-small chance that an ...

I suspect there will be other perspectives, but I'll get things started with an answer in favor of deleting most comments in these scenarios. Possible criteria: The comments are "chatty" without contributing anything that advances the question toward an answer. Examples are "thank you", "good question!", or "I don't know&...

I was thinking about making an original post to help others understand the Schrödinger equation as a differential equation, instead of to ask about the Schrödinger equation. PSE posts need to be Q&A. Essentially make the question as if you were actually asking it and didn't know the answer. Then you can make an answer yourself. The post should not just ...

Well, your posts have to follow the Q&A format of the SE sites. And yes, you are allowed to self-answer, cf. e.g. this meta post.

Yes, see Do we want and need a set of canonical questions with canonical answers? I think this needs to be used with care to avoid turning the site into a blog. In the past when I have been contemplating a post like this I have usually asked here if people think the specific post I had in mind would be a useful contribution. The question you describe sounds ...

One could, of course, find some version of such a question that has some nuance that makes it novel. For the vast majority that you mention, however, you've essentially answered your own question: The large number of variations of the question with answer here and on other easy-to-find resources suggests strongly that the asker of such question now didn't do ...

I think you got the most important part right about reviewing edits: if you can't tell whether the edit is an improvement or not, skip it and let it be reviewed by someone who can. This applies to any edit on any SE site, not just formulas. Having said that, formulas are used in a context, at least in good answers. That context often allows you to ...

In my mind, the most upvoted answer should appear at the top. If this is not the accepted answer, the accepted answer should come in second. At worse, this will encourage users (including the OP) to reflect as to why the accepted answer is not the most upvoted in situations where this occurs.

"Aren’t there clear ways to interpret this question that are consistent with reality? " None that I can think of. What's an example of one of these "clear ways"? The nonsense about limiting behavior is clearly not an example, since every single change in velocity is an increase in velocity in some frames and a decrease in others. I ...

I don't think I have ever downvoted this kind of questions, or at least the ones I think you are referring to. I do think I had voted to close a couple in the review queues. But I reckon that the vast majority of these questions, especially when asked by (new) low reputation users, can always be answered by some variation of "there is no rest frame for ...

Just to give some voice to the data: Nihar Karve created (and I helped refine) a SEDE query, Questions with accepted answer pinned above highest scoring answer which lists the threads affected by this potential change. Under the current dataset in SEDE, the change would affect 5505 threads, which seem to cover a decently thorough cross-section of the site'...

Yes, we should avoid shortened links. There is no need to use shortened links on our site - almost no post ever runs into the upper character limit for posts, and by default you should use links as hyperlinked clickable text [text](url) so the length of the URL is entirely irrelevant because it is not part of the visible text.

Well, we already have an against pinning to the top answer, so I'll do for pinning to the top. I personally like the idea of having some control over the ordering of answers in my questions. I can imagine many scenarios where this is actually a good thing: In general I would say that the person who asked the question is probably the one who is most likely ...

On Physics SE the best answer is selected by the community. That, IMO, means the answer with the most votes. It is the answer of most use to the community and hence to Physics SE going forward. For that reason I think it is valid to make the most up-voted answer the one at the top of the list. By logical extension, the order of appearance should be vote ...

I think this is a terrible idea.

I don't think formulae are really special in this regard: If you see an edit but you cannot tell whether it actually improves the post or not, skip it. Whether that's because you're not familiar with the formulae or the topic of the post in general is immaterial. If you see an edit that corrects a typo, approve it. If you see an edit that actually alters ...

I would say, as a general rule, that geographic limitations on this type of question are not appropriate here. Asking for what's popular in a specific geographic area will produce results which are only useful to a thin sliver of future visitors, and that's enough to sink that idea. Resource-recommendation questions are hard to get working correctly, and ...

I don't think we should. Although thank you comments don't bring anything pragmatically useful to the discussion at hand, there's nothing inherently wrong in expressing your gratitude towards someone who helped you. Even though there's no moral value in flagging these type of comments, I don't think it's prudent to encourage it since it might be interpreted ...

Perhaps if you argue from a very short-sighted, by-the-rules perspective; and indeed, retaining this argument for deleting these comments is probably useful if their volume ever gets out of hand on particularly popular questions. That said, I doubt it's healthy in the long-term to discourage people being nice to each other. Who's it hurting?
