The rule on other science SE sites I'm on is that SI units have supremacy (except on Physics.SE where natural units have primacy when the context suits). I propose adopting the following rule here. SI units are mandated. If someone insists on using imperial units, they should use the SI unit, and then put the equivalent imperial unit in parentheses.


I believe it is impossible to do so for every post. Some of the questions posed are basic textbook level and a reference in that case would be to one of many text-books. It is clear as in all science that citing your sources is useful and necessary but clearly there is a fine line when it should be "common knowledge" and in such cases one can ask common to ...


I'm a small-time open-access publisher, not a lawyer, but have done lots of research about this, and spoken to Creative Commons counsel about it. So I will make a proposal. @Neo wrote in the question I mentioned: i dont think that is a copy right issue: journals are meant to be cited, as long as they are cited. I do not need any permission to use a ...


I think we should allow Homework questions as long as: There is clear attempt at a solution beforehand by the asker. Answers are given in a responsible way (IE showing instead of doing). Both are harder in practice.


Any answer that points to just some other page, is effectively not an answer. If the answer doesn't stand on its own merit, in the absence of the information at the other end of the link, then it's not an answer. We're trying to build a body of expert content here, not just a collection of signposts. That means you've got several options. Please, as part of ...


I suggest adopting the physics.SE policy on homework as it is written, and not attempt to revise or relax it for earth science. They have expended a lot of effort on it. It is not a blanket ban on homework questions, but it discourages them.


Imperial units are still used in the oil and gas industry in the USA, which unfortunately leaks out into the rest of the world. In Australia sonic log measurements are still often reported as microseconds per foot, and well bore diameters are reported in inches, for example. I second EnergyNumbers proposal. Imperial units are just stupid.


Recommendation questions should be off-topic here. They have no objectively correct answer. They lose their relevance over time. They're not science: they're popularity contests, they're shopping trips, and they're frivolous fluff. These factors make recommendation questions unsuitable for a site that aims to build a canonical body of expert knowledge.


You may change your chat's parent site to here. However, considering that you're currently suspended on the current parent site, changing it doesn't lift your chat suspension. Reference: Can you still chat if you change your parent site from where you are suspended to other site?


Straight out recommendation questions should usually be off-topic here. But some recommendations can be salvaged, by being converted into a "what features are important?" question, or even better "what does this specification mean?", and "how do I know what to look for?" questions. A really good example is this question on ...


The main issue for me here is not even the copyright (though it is of course an issue) but more the fact that those gifs do not bring anything to the question asked, and are in fact rather distracting (for instance i'm currently writing this answer with my browser window reduced enough NOT to see that gif consistently while typing this).


A blanket ban on homework wouldn't be appropriate, unless we use a very specific and narrow definition of the word "homework" and make such a definition clear to all users. I think that homework questions that are suitable for SE in every other way should not be off-topic merely because they are homework questions. Most typical homework questions will not be ...


Yes, we should have citations on every answer. There are plenty of speculators and chancers in this family of subjects out there, and we'll do well to deter them. And no, Wikipedia is not a reliable source. Any fool can edit Wikipedia to say what they want, when they want; and content disputes there sometimes get resolved by a loud obsessed fools over-...


I am a bit put off by the idea of some group of people deciding what they will 'allow' before it comes along. As I understand it, the point of SE's brilliant system of rep and voting lets the community determine — iteratively and organically — what is and is not interesting and useful. I guess I just don't understand why there needs to be a policy in place ...


I would think that they are OK as long as they truly add something to explain what the question is about.


Physics appears to have a very good policy toward homework questions (linked in the question). I suggest that we adopt it, or something close to it.
