@Sofia: The irreversibility in atomic decay is almost exactly the same thing as described in the Caldeira Leggett model.
In both cases irreversibility only shows up if you assume you have an infinite number of degrees of freedom in some "environment".

Q: How to respond to a pool of existing poorly worded questions without creating a duplicate?

DanielSankWhat's the right way to post a self-answered question on a topic which underlies many existing questions? Consider in particular a case wherein many questions have been posed about Topic X. These questions are not particularly well written because the askers are not themselves experts in Topic X...

You know, when a person's only 4 questions on the site are at -6, -1, -1, and -6 but the net rep change is only -3, it does make you wonder if perhaps we're a bit soft in how little downvotes affect rep.
 
6:41 AM
@ChrisWhite Don't you think that if a question is really bad, it will make more sense to close the question than to continuously pound it with downvotes ?
 
7:14 AM
So... what do you guys think? I tried to debunk the Creationist radiocarbon dating question physics.stackexchange.com/questions/154588/…
 
@ChrisWhite maybe, but it also means we're soft in how much we downvote
 
@ChrisWhite Heh, yeah...
It's funny to look at that person's though process, as reflected by questions asked.

Hi, is anyone up?
Annnddd is anyone willing to help a high school student review his test? I fell asleep and it's 3 AM and literally everyone else is asleep.
NEVERMIND, I FOUND SOMEONE ELSE WHO IS UP. But I'd still appreciate help on a couple of problems.

Q: Which flag do I use for an inappropriate post?

David ZOther than off topic flags, there are several different types of flags that one can cast on a question, answer, or comment. What are each of these flags for? Question and answer flags: spam offensive/abusive/hate speech not an answer very low quality other Comment flags: rude or offensive ...

^^ I would like to collect some better examples for that question
 
10:58 AM
I can't recall which Supreme Court judge said you can't define pornography, but you know it when you see it. I think that is also the case for "inappropriate" content.
@DavidZ
The work as a whole must lack "serious literary, artistic, political, or scientific values".
Notice that the work as a "whole" is being considered because we can always edit out the "inappropriate" parts for examples to be used in questions like yours, while saving the good content to make this a better site.
 
11:50 AM
@skullpatrol: There's a good talk about censorship by Yale Prof. Hungerford: oyc.yale.edu/english/engl-291/lecture-20
The focus is somewhat more on works of literature though.
 
12:30 PM
@JamalS Thanks for sharing :-)
Have you seen this Professor?
 
12:58 PM
@skullpatrol I actually disagree with that statement (the pornography part!)
Nice meta post, @DavidZ.
 
1:24 PM
@JamalS WOW! that was good, thanks again :-)
@Danu yes, in that way you are correct...
 
1:41 PM
@KyleKanos Unfortunately some users with editing privilege are using their rights very poorly! E.g. bobie keeps editing some of my posts and messed up the structure for absolutely no reason. I hope you will moderate this in future! Thanks
 
@user929304 Sadly, we cannot. Once a user has passed 2,000 rep, they're allowed to apply edits immediately
If bobie is making unnecessary edits that you feel are ruining your posts, you can choose to roll-back to the prior version (click on the timestamp above bobie's name & select "rollback")
 
@KyleKanos thank you for getting back to me, alright I understand, no problem. Thanks
 
sounds like a job for a mod
 
@KyleKanos: I need the attention of the moderators. I asked a question, it was put on hold because it wasn't complete. I completed, but the hold wasn't removed. Instead, I got a minus. What for? Is it a low level? Is it too difficult? In such cases I should get a notification. I know that the moderators don't intervene in votes, but it seems simply that someone dislikes me. Please, I insist, look at the question,physics.stackexchange.com/questions/154638/….
 
I saw the question (even edited it)
My guess is the -1 came from the fact that you had half a question
Note also that there are currently 4 reopen votes (requires 5 to reopen)
 
1:55 PM
@KyleKanos : please be kind, can you repair the situation? A -1 on a question produce in people the idea that the question is silly.
 
If by "repair the situation" you mean get rid of the downvote, I cannot do that.
No one can, except the person who downvoted
I did, however, upvote it, so it shows the "goose-egg" (zero)
(I don't think you can upvote questions in the reopen review queue)
 
@KyleKanos: I tank you a lot.
 
@Sofia: Question reopened now.
 
@Danu That post might be better suited for Skeptics that Physics. Don't get me wrong here, but your point is debunking the fraudulent claims of a few misguided individuals. It doesn't really do anything about the issue of C-14 being a bad method of radiometric dating past 40 kyrs--that requires discussing U-Pb or K-Ar or whatever tests.
 
@Danu How did you find that video?!
@skullpatrol: I wouldn't watch that... more like an amateur teacher; definitely not a professor.
 
2:37 PM
@Sofia: When you say "it seems simply that someone dislikes me" that is exactly the kind of thing that makes people say you're a little bit rude. You seem to keep assuming that you need special attention, in this case just because you got a -1 on a question. You are not different from the rest of us. If you get a -1 it's because someone thinks there was something wrong with the question. It's not personal.
 
@KyleKanos Okay... I could get behind that.
@JamalS I'm a bit older than you, and spend a lot more time on the internet than you ;D
@DanielSank I second this remark. @Sofia, please, don't assume there's some kind of conspiracy against you - not even a 1-person one ;)
 
3:30 PM
@Danu That's what the conspirators would say, wouldn't they ;)
 
3:49 PM
Conspiracies can be funny
 
4:00 PM
@ACuriousMind how are you? holidays doing you good?
@Danu finally done with classes? :D (no excuse for not playing chess anymore :pp )
 
@Phonon Heh, yes they are :) How 'bout you?
 
@ACuriousMind thanks, same, except for this toothache busting me up pretty good...
 
Ooo, I know: give yourself a charlie-horse so that your mouth doesn't hurt anymore!
 
@KyleKanos :DD actually it stops hurting for a while when I slap myself :O
 
@Phonon Aw, that sucks. Too many sweets? ;)
 
4:04 PM
@ACuriousMind :(
 
Mmmm, sweets.
Making my mouth water
 
LOL
 
Actually, what I think I'd rather have (that I haven't in the last pair of days) is yogurt + raisins + cinnamon + honey + nuts
 
definitely sounds yummy ;D
 
It is, though I often replace yogurt with thick kefir
 
4:09 PM
@ACuriousMind sigh...looks like some people don't appreciate your non-wavemechanics view of QM, some of the comments are funny at times though :D
ahh yes yes I know it, had no clue it's called this way in English :D
 
It's like yogurt (made from milk via active bacteria) except thinner and drunk instead of eaten
 
@KyleKanos gonna try your combination right off, wish me luck with the proportions...
 
There's no wrong way to do it ;)
I recommend a handful each of nuts & raisins
One spoonful of honey
A dash of cinnamon
And a bowlful of yogurt/kefir
 
oki doki thanks ;)
 
It just occured to me that I haven't eaten yogurt in years :D
 
4:15 PM
@ACuriousMind You're missing out.
 
@ACuriousMind years? ... wtf haha!
 
I...just never seem to buy it
 
guys
 
Haven't even thought about it, really. I completely forgot about the existence of yogurt :D
 
sth funny, I found this vid while ago, hate the title though.... I d love this guy as a teacher :DD so funny if nothing else, here it is
@ACuriousMind you need to cut on the Glühwein... :)
 
4:19 PM
lol
No one takes my Glühwein away :P
 
Lol...the sidebar from that youtube link gave me this gem:
 
wat
What the hell should 16 be the sum of?
 
No idea
But when you don't know math.....
 
But they seemed to be pretty sure about it - they definitely didn't just guess at random
 
I always remembered the audience being wrong more often than not
 
4:33 PM
lol these sidebar related videos... so random
 
If you click on too many of them, you're gonna land in the weird part of YouTube
 
lol
 
4:46 PM
@ACuriousMind hahaha :D
 
5:06 PM
:D
 
5:45 PM
@ACuriousMind I'm pretty sure that, in this case, we were coming from the weird part of youtube

So there I am, answering an everyday science question with words. The whole time I'm thinking "It sure would help to have a diagram to refer to. But I'm lazy. I bet John Rennie would make a diagram though." Seconds after I post an answer, John Rennie posts one with a perfect diagram.
 
Well I'm pretty sure Rennie's got a computer interfaced with his brain so that he can make those images hella fast
 
user54412
@DavidZ I'm curious why you approved revision number 4 here
 
user54412
The OP wanted a horizontal rule. Someone comes along and mutters something about changing standards, blah, blah, the "horizontal rule" is not to be used for horizontal rule... and makes the very definition of an unnecessary edit
 
user54412
This after the OP was already flustered by other users forcing personal style on him
 
@ChrisWhite because the words "context" and "question" are headings. Headings should be written using heading markup, not bold text and a horizontal line.
In general, using the semantically correct markup is better than not using it, therefore that edit represents an improvement in the post.
It's not a matter of personal style.
 
user54412
6:43 PM
But this isn't a case of pure semantics -- it's a case of visualization too.
 
user54412
The edit changed the look of the post, which was perfectly readable
 
user54412
the fact that there is a live preview means posts should be formatted for look, not underlying code style
 
@ChrisWhite ...no, I'm pretty sure that's not correct
 
user54412
Otherwise I should go through and ravage 90% of the latex here, what with people using all the wrong commands to get the look they want
 
Yes, you should. I do it all the time.
I mean, there's also the guideline not to edit too many posts at once, so I'm not actually saying you should fix all the misused MathJax syntax out there
 
6:47 PM
[A, B] \ne 0 @DavidZ
 
but something like e.g. replacing |\psi> with \lvert\psi\rangle does represent an improvement in a post because it replaces semantically incorrect markup with semantically correct markup
 
user54412
You would actually change $x_{\rm stuff}$ to `$x_\mathrm{stuff}$?
 
Yeah. I probably wouldn't consider it worth making an edit just to do that (for the aforementioned reason), but if I were editing anyway, I would probably change that.
 
user54412
@DavidZ I agree it improves, but I disagree why. It improves because the output of |\psi> looks awful, and the output of \lvert\psi\rangle looks right. If it doesn't look wrong, why would I change it?
 
Change it to be right, not just to look right. This makes SE posts more compatible with screen readers, search engines, and other automated scripts.
Incidentally MathJax is not exactly LaTeX, and the rule where you should use \mathrm rather than {\rm }, which applies in LaTeX, doesn't necessarily hold in MathJax. (It might hold, I'm not sure)
But in general, changes which are purely semantic are valid edits.
If we had a \ket macro, it would be valid to replace \lvert\psi\rangle with \ket{\psi}. If siunitx were implemented in MathJax, it would be valid to replace 45\text{ J s} with \SI{45}{Js}.
 
user54412
6:53 PM
Well, for the record, I will strongly object if anyone removes --- (which I use rather often) from my posts. That's right, I use it to separate sections, not always "a thematic break between paragraph-level elements."
 
Separating sections sounds like a thematic break between paragraph-level elements to me
if that is in fact the proper use of --- (I'm actually not sure, but I do know a line under a heading is not the proper use)
 
user54412
I don't separate paragraphs from paragraphs, I separate paragraphs from section titles. And I don't see how you can approve of that but object to separating section titles from paragraphs.
 
Wait, maybe I don't understand what you're saying? I thought you were saying you do
paragraph

---

# Section
 
user54412
Yes
 
Yeah, I don't see anything wrong with that. I mean, I think the --- is unnecessary, but if you're going to use a horizontal rule I don't know of any semantic reason not to use it that way.
What would be wrong is this:
**Section**
---
paragraph
 
user54412
6:59 PM
and while I don't personally put lines underneath # Section (which, by the way, I often write **Section** because the internet believes in unnecessarily large fonts), I can imagine some styles that do.
 
@ChrisWhite haha yes it is kinda funny that that specific post got re-edited again :D
 
user54412
I'm sure there's a typography name for lines under sections, but I have no idea what it is.
 
Well, SE markdown is like LaTeX in the sense that you should write what you mean and not worry about what you want it to look like
Incidentally rather than using **Section** the right solution would be to lobby for SE to change the CSS
 
user54412
true, but don't we all go back at the end and make all sorts of visual tweaks to latex, probably breaking semantics along the way to make a pretty document?
 
No
 
user54412
7:00 PM
@DavidZ Now that I could get behind
 
at least, I don't
 
user54412
but that seems like a low priority
 
Yeah, it is a low priority
 
user54412
@DavidZ well, most of the content of tex.stackexchange disagrees, especially the power-users there who break things all the time :)
 
user54412
(too much for my taste, but that's their style it seems)
 
7:01 PM
Anyway I also think the heading fonts are too large but I use the heading markup anyway
 
there are so many poorly formatted posts on SE, why people are getting so anal about this one? because it's getting high number of views?
 
@ChrisWhite in my experience there, all the breaking things is so that you can implement things in a semantically correct way and also get them to look right. I've often seen the power users make a fuss when someone tries to blatantly abuse markup for the wrong purpose.
 
looks like bobie and blackhole basically re-edited to the same result ...
 
user54412
@Phonon probably. Honestly, I don't see every post, but I try to look at every physics post that makes it to the hot questions list, because it seems worthwhile to make sure the most viewed questions are being handled well and present the best face of our community.
2
 
@ChrisWhite fair enough I guess, nothing's like a super long & poorly formatted answer though... see this one ARGH....
 
7:06 PM
@Phonon Also, probably because the author complained about his posts being re-edited to fit a style he does not agree with.
 
user54412
that's a bit stream-of-consciousness I suppose
 
@alarge ah, then strange that a new edit was allowed...
@ChrisWhite :)
@alarge but I can imagine that it can be frustrating that you format your post for some good reason and a second after submitting it gets all messed up by some editor :D
 
if it's misusing markup for the wrong purpose, it wasn't a good reason in the first place
 
7:28 PM
@DavidZ What's the definition of "wrong purpose"? I personally don't believe in draconian rules and strict bureaucracy. Rather, the C community puts it well: "Trust the programmer." If the author believes it helps the clarity of the post when they use ---, to the point that they revert edits, let them.
2
 
8:02 PM
@alarge Stack Exchange posts are communally edited by design. Even though Physics SE's culture exhibits a lot of respect for individual authors' intent this still implies that there exists some kind of consensus on how the markup elements should be used and author who stray too far will get their posts edited.
And they should. Some people simple have really awful preferences for markup.

whoever's into Tom Waits, will love his new album, listen away here
 
Hmm. I got about a minute into it before I had to turn it off. Wasn't too interesting to me, sorry
 
@KyleKanos sure man, don't be sorry, he's not everyone's style ;)
maybe the track starting at 5:47 will draw you more...
 
Almost bearable that one
 
@KyleKanos btw tried your recipe, it's A BEAST OF A COMBO! loved it :D

OP answered & accepted his answer to his own question
But it looks to me like he took everyone else's ideas, placed it into a single answer and then blasts the community for downvoting it
 
10:25 PM
@KyleKanos: I've only skimmed the posts, but a priori it seems the OP doesn't deserve the downvotes...
An OP has a right to pick any answer as his accepted answer; whether that is an amalgamation of others or not is irrelevant, no?
 
@KyleKanos It is called plagiarism
OP didn't credit the others efforts there
 
@hwlau: Can you link official SE policy on plagiarism? I haven't been able to find it, only meta posts.
Actually, maybe that's something that should be added to the initial FAQ / Q&A for new users.
 
@JamalS I think there are no such thing. But you can't directly copy anything elsewhere because of the CC lincense
it is not the most strict form of plagiarism, but the OP didn't mention the others work on it
just like no citation of other's paper
 
@hwlau: Doesn't the creative commons license allow one to redistribute and/or modify work?
 
@JamalS Yes, you can
but it is different issue if you credit the original author or not
most people think it bad to not mention others' work
 
10:35 PM
Also, SE posts aren't exactly journal submissions... Although it's not a forum, I don't think it has a 'status' higher than that of a forum, in which case I don't think citation is required. (Of course, the issue is different if, for example, a book is quoted.)
Regardless, notice what appears when you hover over the downvote button: "this post is not useful."
 
> Attribution — You must give appropriate credit, provide a link to the license, and indicate if changes were made. You may do so in any reasonable manner, but not in any way that suggests the licensor endorses you or your use.
 
I just think the downvotes were a bit harsh for what he did.
 
I was wrong
@JamalS probably, but most people don't care, because they know it already
I did asked, answered and accepted my question myself and get 10's of upvote
it just basically depends on how you do it
 
11:24 PM
@Phonon : Tom Waits is not exactly Xmas carols :) Thanks for sharing.
 
@Qmechanic indeed :(, my pleasure! Actually just now I was listening to this one, you probably know it as well.
 
No. My interest for Tom waits was mainly spurred by the movie Down by Law and that period.
 
haha oh wow, really liked that movie, the first couple of scenes with Benigni arriving at the prison were too hilarious :D, nice movie overall!
I quote: "if looks could kill, I would be dead now!" ;)
