I want to flag a Chemistry question on Physics, but the options available to me in the flagging window do not include migration to Chemistry. What should I do ?
What causes the melting point depression known as a eutectic point?
The temperature depression of a eutectic point can be calculated from the enthaplies and entropies of fusion of the two substances.

@dmckee: we have a clear case of malicious serial downvoting here and you know it. Now fulfil your role. I’m not insisting with my answers, I respond with robust references, and yet I’m deluged with downvotes by the popscience trolls you’re turning a blind eye to. See for example this: physics.stackexchange.com/questions/195297/…. Six downvotes! One each for Einstein, Shapiro, Baez, Wright, Magueijo and Moffat.
So puhlease, don’t give me the modern author not liking the semantics or weasel words about Einstein is a prophet. What we have here is a bunch of trolls misleading students and doing the site down whilst good contributors vote with their feet. And if you ain’t part of the solution, you’re part of the problem. Capiche?
@0celo7 : actually, you're part of the problem. @Kyle Kanos : Don Koks is the editor of the PhysicsFAQ/Baez website. Like me he's what you'd call a "relativist". And no, I'm not the troll, I give the answers, not the downvotes. @HDE 226868: I'm complaining about the trolls who are ruining physics stack exchange. There's good reputable historic posters on this site whom I know, but they've stopped posting. Houston we have a problem.
@JohnDuffield You can't make the claim that it was serial downvoting because it was almost all things that you had posted within the last couple days. That's a strike against that. Second, most (not all) were terrible posts. I don't blame whoever downvoted the answer that started with "I can only answer with opinion rather than facts"
@Kyle Kanos : I've talked to him, he describes himself as a relativist. He rewrote the Beaz speed of light article after we conversed. The old version is here desy.de/user/projects/Physics/Relativity/SpeedOfLight/… and it contradicts itself. Look at the last section.
@JohnDuffield I'd argue that this one is correct, $c$ is a constant and not a function of $x^\mu$.
@JohnDuffield And no, I'm not the troll, I give the answers, not the downvotes. What on earth do you think a troll does? They give bunk answers based on bunk physics, precisely as you do (for the most part).
Dark mass, not dark matter.
The mass which fills 'empty' space is beginning to be referred to as the 'dark mass' in order to distinguish it from the baggage associated with dark matter.

@HDE 226868: the serial downvotes aren't just on my recent replies. And they weren't terrible posts. They were good answers. Much better than yours. For example see physics.stackexchange.com/questions/195951/…. Who voted for your pathetic answer? Larry the Lamb and Sooty? You're a sixteen-year old nerd. Back off kid.
@Kyle Kanos : c is not constant. Go and read the Einstein digital papers: einsteinpapers.press.princeton.edu/vol7-trans/…. If the speed of light was constant in the room you're in, your pencil wouldn't fall down.
I recall that it was annav who gave it, but it revolved around the observations of the galactic motions and the fact that many smart people studied them for many years to come up with the theory
@Kyle Kanos : or how about Don Koks the Baez editor? See this: math.ucr.edu/home/baez/physics/Relativity/SpeedOfLight/… And I quote: "In that sense, we could say that the 'ceiling' speed of light in the presence of gravity is higher than the 'floor' speed of light". You don't know about this because you've been spoon-fed some popscience pastiche of relativity that appeals to Einstein's authority whilst flatly contradicting him. Yes, that's the size of it.
He's not Baez's editor, he's the editor of a usenet site that is hosted by Baez. You're trying to equivocate Koks opinions with Baez, and that's not necessarily the case
AFAIK, Baez hasn't actually written any of the articles on that site
Heck Phillip Gibbs, well known for holding non-mainstream views, was an editor for the site
@Kyle Kanos : oh duck and dive. Go ask Baez about it then. Make sure you mention my name and my references to Einstein and Shapiro and Wright etc, and how you think Einstein should be dismissed as a prophet. Gibbs wrote/cowrote the old article that's on DESY, the one that contradicted itself, the one that Koks rewrote.
Come on, who's got the guts? @Slereah : no, I don't have anything on viXra. Somebody put something of mine on there a while back without my permission and when I contacted them they obligingly removed it.
ADS doesn't have a John Duffield either, so it seems just a book
Hmm, first review on the book,
> WARNING: This book contains a lot of personal theories about space, time and matter, and doesn't bother to highlight for the reader what is established physics and what is not. Parts of it flatly contradict what modern theoretical and experimental physics have discovered
@Slereah : Don't you get it yet? See Ned Wright saying In a very real sense, the delay experienced by light passing a massive object is responsible for the deflection of the light. The relativity you've been taught is Kip "time travel" Thorne relativity. It appeals to Einstein's authority whilst flatly contradicting him. Yeah. If you want details, ask a question.
@Slereah : And where have you been? Someone told me that each equation I included in the book would halve the sales. Who said that? My little 2009 self- published effort isn't really on sale any more, but Amazon are a law unto themselves. At least the price is down from the £500+ it was a few weeks ago. That must have been a signed copy. Collectors item!

@Slereah : that's just a malicious review from a troll. I refer to Einstein and the evidence etc, I'm not some "my theory" guy. The other reviews give you a better balance. If I was writing it again I'd change a few things, but not that much.
Can we please keep this friendly? @JohnDuffield was rude earlier, but he has subsided, and I think that he's having things heaped up on him, which is rude in return. cc @Ocelo7 cc @Slereah
OK, who can I email about why they don't post on stack exchange any more? Would any of you guys like to volunteer any answers to that? Only I'm looking at my reputation, and I'm seeing an awful lot of red for answers that refer to Einstein or Minkowski or Maxwell etc, or to bona-fide contemporary authors and hard scientific evidence.
I have a laptop here with 12.04, and I think I'm about to nuke the installation because [reasons], so I'm debating whether to go back with 12.04 again or make the leap to 14.04
heard 14.04 was terrible when it launched, wondered if they've ironed out the kinks yet
@Slereah : are there any other competitor websites you care to recommend? Only I like it here, where I can further your education. @ACuriousMind : out of close votes? Do you guys hang around closing down questions then? Only I thought the idea was to answer the questions. And is it my imagination, or have I seen some "already answered" questions that haven't been answered at all?
@JohnDuffield running out of close votes is pretty easy once you have access to the close review queue... until you see it, you can't appreciate the amount of unambiguously close-worthy questions that need votes spent on them
@gonenc ennnnh, I was using the latest Ubuntu every 6 months for a while, but got tired of the bleeding edge, would rather be on a LTS these days
@JohnDuffield It is an intrinsic feature of the SE model to have active community moderation, see, for instance, A Theory of Moderation. Yes, I take an active part in moderating this site, closing questions that are duplicates, not about physics, too broad, or just so confused that one can't tell what is actually being asked. There are 24 of those close votes per day, and I'm out of them for today.
@Kyle Oman : you need 3000 votes for that. And once you're past 2000 votes, it would seem you start attracting attention. Then the malicious serial downvotes (which aren't really serial downvotes of course) start rolling in, and it's uphill all the way.
@KyleOman I should say I haven't had any problems with ubuntu 14.10 gnome 3 as I've said before, I don't use unity so if you do I cannot give any opinions on that matter
@alarge only if I had the stomach to do that :D :P
@Slereah : Something else that's strange is that I see a lot of historic posters here who aren't posting any more. @ACuriousMind : I've seen questions closed that arguably should not have been closed, where there's no adequate answer on the duplicate, or where the closer has given a poor answer to a somewhat-similar question. I look forward to being able to vote on this, but I'm getting the feeling that some other people aren't.
I use unity because it's the default, but have no particular attachment to it - my work desktop is Fedora and... hell I don't even know what GUI this is anymore
@ACuriousMind Also, to be serious for a minute (heresy I know), experimental physics is like 70% engineering. I do feel strongly that this is important and often misunderstood by the general population and other physicists.
@JohnDuffield duplicate-ness has nothing to do with answers - are the questions the same? if yes -> duplicate, if no -> not duplicate... if there are good answers on the closed question, sometimes they can be migrated to the open one, on request
@ACuriousMind your meta post reads like "I have more downvotes than all of you puny maggots. I am literally the master of downvotes. Here is my creed:"
Then again, I engage in accepted, mainstream physics. @Kyle Oman : I've seen some questions that have been closed as a duplicate, but when I've followed the link to the alleged duplicate, it's not the same, and there's some second-rate non-answer by one of the names who voted for closure. I can't give any examples of this as I speak, but I'll make a note of any more instances I come across.
@0celo7 : I'm the one who gives the references to Einstein etc and the evidence. The people who airily dismiss that as theology are not engaging in physics. Mainstream or otherwise.
@Slereah of course, to deal with the disconnect between js and other languages the solution which is gaining traction is to write the SERVER is js too! Yay! Let's all go down the road to software hell holding hands together.
On StackOverflow they have a hook that pings you if your question title includes certain words.
I just asked a question about a weird floating point behavior in numpy. When I tried to submit, it sent me to the top of the page with a warning suggesting that I read certain articles about common problems with floating point operations.
We could use this.
A couple of obvious cases where the user is probably doing something wrong come to mind: 1) Title includes the word "question" 2) Title includes "uncertainty principle"
