Is non-mainstream physics allowed here? No, questions and answers about non-mainstream physics are not allowed here. We are not a substitute for peer-review, and cannot evaluate new theories. While some questions can lead to legitimate new theories, the question will need to be specific in order to fit this format. What defines mainstream physics? Mainstream ...

No. You can't. Every user with the requisite rep is entitled to vote on the content you post. That's by design: we use a crowd-sourced evaluation. There may exist users that cast more downvotes than up, and that is allowed. It just means that user has very stringent standards of quality; as long as those standards are applied evenly the user is free to ...

Yes, there is a \tag{} command. E.g. $$ 1+1=2 \tag{1} $$ produces $$ 1+1=2 \tag{1} $$

As a user that frequents SE sites intermittently (and with less reputation than most, including yourself), please interpret my upcoming critique as independent from the high-rep user/users you believe are targeting you. You seem to be intentionally ignoring the community's critique, falsely assuming that you are the victim. I appreciate your curiosity - it ...

Nope, moderators don't know who votes on their posts. We can get access to some aggregate information about votes to use for identifying fraudulent behavior. For example, if two (or more) accounts are suspected of belonging to the same person, we have a tool that reveals whether there is a suspicious pattern in how the accounts are voting. But the ...

There are a set of automated quality control policies active on the site that set temporary (and no-so-temporary) bans on posting. These bans are specific to either questions or answers and are triggered when a user has too many recently closed, deleted, or down-voted posts of the same kind (question or answer). They are sometimes called the 'q-ban' (for ...

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 ...

There are multiple reasons why it's better to link to abstract pages rather than directly to the PDF versions: Mobile users and users with slow internet connection prefer an abstract page over a PDF file. (Also, downloading PDFs can redirect to other applications instead of staying in-browser; this should be an explicit choice on the part of the reader.) ...

Let me draw your attention to the first sentence of the "About" page Physics is a question and answer site for active researchers, academics and students of physics and astronomy. The level of the site is defined as being interesting to serious students of the discipline,and has been that way since its inception on Area51. This level of professionalism ...

It seems MathJax supports size Latex commands: \tiny, \scriptsize, \footnotesize, \small, \normalsize (default), \large, \Large (capital "L"), \LARGE (all caps), \huge, \Huge (capital "H") Which go from smallest to largest. A quick test showed that \large or \Large worked rather well for the equation you have above (getting larger might be just too much). ...

Well, you were suspended last time around for posting low-quality questions (which are a problem because they create work and annoyance for other members of the site) and making scores of edits that didn't substantially improve the posts being edited but did clog the active lists with questions that folks had already seen (which also creates work and ...

Simple: don't write answers to questions that are going to get deleted. Homework questions get deleted for a reason: we don't want them here. If you answer poor-quality homework questions, you are nullifying the effect of the homework policy and you are providing an incentive for the users whose questions you answer (as well as others who see that those ...

Don’t say things like “I know [whatever] due to deep research”. This is pretentious because it is obvious from your questions that you are not yet an experienced physicist, and saying this kind of thing shows disrespect for those who have done deep research. Similarly, do not mention “the science channel”. We’re all for popularizing science, but you can’t ...

You can still go back to the election page and click on the 1st, 2nd, and 3rd choice buttons of other candidates to change your vote. You can do this as many times as you want before the election period ends. If you don't want to vote for 3 different people, you can also select the same candidate for more than one of 1st, 2nd, and 3rd. (It doesn't make your ...

You are editing a lot of posts which are closed and have a negative score. Such questions are regularly deleted by an automatic deletion routine (often termed the "roomba"). When a question is deleted, all associated reputation gains and losses are reversed. In particular, the 2 reputation you gained from suggesting an edit that was subsequently approved ...

I guess if you wanted to create a place for negative comments, you would have to also create a place for positive comments. Anyone can run for this - I even considered it. You do not need to be a specialist in your field to be a moderator. You simply need to: be able to listen support the wider community (not necessarily a vocal individual) take actions ...

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 ...

OK, there are a couple different things going on here. Potentially inflammatory posts It's certainly true that chat bystanders can often tell when a conversation is about to turn nasty. And you're definitely right that it's better to prevent nasty exchanges from breaking out in the first place than to allow them to happen and deal with them afterwards. ...

To be very frank: you shouldn't even be contemplating this questions; you should always vote the quality of the content and never the user who posted it. Nor will anyone tell you what the limits of the automated vote-misuse detection system are. That would rather defeat their purpose.

I would interpret the downvotes on the answers to both of those questions as saying don't answer this kind of homework questions and I agree with that perspective. Providing answers to obvious do-my-work-for-me questions only encourages more of them, and they are a clear drag on the quality of the site. This is a gray area, but if I see a Q&A pair ...

This is the message you're shown when you try to ask a question. I'm quoting it in its entirety in the hope that you read it this time: It looks like you might need a break - take a breather and come back soon! You've asked 4 questions recently, some of which have not been received very well by the community. Everyone learns at their own pace, and it’s ...

Your first obstacle is that you need 1000 reputation points to create a new tag. If you think a tag is missing and don't have 1000 reputation points, you can suggest it in this meta post. If you have 1000 reputation points, there might be another obstacle: Certain words are blacklisted, e.g. physics. Returning to OP's specific question, a 'physics' tag would ...

To be perfectly clear: We expect you to take responsibility for your actions. This includes every one of your actions on this site, but in this particular context, it's worth emphasising that it includes setting bounties, allowing other people to access your account, and lying or other deceptive behaviour. If you set a bounty and then regretted the ...

Some suggestions: Stop using your "student" notes as a reference. We do not care where your question comes from, and unintelligible scribbles from a student are of no use to us. Stop using books/webpages in Italian as a reference. This webpage operates in English, and if that does not work for you, you'll have to find some Italian physics community ...

The purpose of MathJax is to make mathematical formulas easier to read, not to emphasize text parts of your posts. Use italic and bold formatting for that. A similar question was asked on Chemistry Meta and I did an experiment with a screen reader. The 'nicely formatted text' So, in the heap of my data it looked like $$\text{Diamond in a coal mine}$$ But ...

It lets you track the question in your favorites tab. In this case, updates to the question (answers, etc) will increment the red counter above the tab (the counter isn't visible if there have been no changes since your last visit), and the updated question will be highlighted yellow. Effectively, it's a way of "watching" the question. You can also use it ...

When you get hit with the automatic answer block, you get linked to a page that describes how your situation and how to get out of it Read it. Now, improve your existing answers. You have some deleted link-only answers; elaborate on them and undelete. Don't ask questions or leave comments in the answer box, such stuff gets flagged and deleted. Do not delete ...

It's secret, and that message is sent rather early on in most cases so you have plenty of time to improve. If you seem to actively be trying to improve, by reading the policies and cross checking, it shouldn't hit you.

(On a related note, the user page for Community on Meta states that it pokes up questions every hour. This is definitely false on Meta, so maybe it can be fixed?) It's true - with the caveat that it doesn't bump if there's nothing to bump. If there's only 1 question on the site that meets the criteria for bumping, then Community will bump it and touch ...

I quote the comment I left on your answer: I'm temporarily deleting this in accordance with our homework policy. Please don't post complete answers to homework-like questions. That's why. I'm not sure what to add to that. (Maybe if you can elaborate on why you were confused by that message, I can provide something more useful.)
