I found this interesting. Of ~300 questions closed for being "Opinion based" this year, only 1 of them was reopened. I don't really think it means anything special, just though that was interesting to note. meta.stackexchange.com/questions/341507/2019-a-year-in-closing

Am I having déjà vu, or is this a repost of a deleted question from the last day or so? physics.stackexchange.com/questions/522782/…

@JMac I noticed that too. It looks like opinion based closures are rarely reopened, across the whole network, apart from a few exceptions. I guess that being "primarily opinion based" isn't just an opinion. ;)

@JMac interesting analysis, it would be interesting to delve deeper. but think the simple story is that reopening is rare, across SE. n00bs are not informed of that basic factoid upfront ofc. on other hand the recent epic rebalancing in favor of questions is a rare paradigm shift.

To me, field physics no longer appears as the key to reality; in contrary, the field, the ether, for me simply is the totally powerless transmitter of causations, yet matter is a reality beyond the field and causes its states."

Though I have flagged it as one.

user434058

@Knight FWIW It's quite a famous song by Pink Floyd.

user434058

11:46 AM

@JohanLiebert I also flagged it when I saw that question.

user434058

@JohanLiebert IMO I would definitely consider it a homework like question. Because only saying that you tried and not showing any efforts/tries is equivalent to not trying at all (that's not really correct but on SE, we really don't know that the OP has really tried it unless he/she posts his efforts, so we are bound to assume that the OP hasn't tried it....

Knight

@FakeMod I know, I just want to know what does this phrase Shine on you Crazy Diamond mean?

user434058

But yeah I just read his two line effort in the comments. So yeah, I am not really supporting a HW question even if it's a past year Olympiad problem. But it seems to me that the majority has a different stand. The post is proubly glowing with +4/-0 . Is it really wrong to call this a HW question?

user434058

@Knight Just Google Shine on you crazy diamond meaning. Within a few scrolls and clicks, you will know its meaning

skullpatrol

@Knight forum.wordreference.com/threads/…

> It means "continue to shine". There is a Pink Floyd song "Shine on you Crazy Diamond", which is a wish that the person in question will continue to "shine" like a diamond (that is, display creative genius).

If you call someone a "diamond" it means they are "rare" and valuable.

To "shine" is to be brilliant.

They are "crazy like a fox"

user434058

@skullpatrol Yeah! I did flag it! But sometimes it feels too cruel to do that to a new contributor :)

skullpatrol

12:07 PM

Yeah, I know how you feel...

user434058

@skullpatrol There are 2 reasons for not answering :- 1) I am not really able to understand why the OP is not able to understand the solution. It's quite an easy question. And the solution is well written and I cannot probably write a better answer than the solution.

user434058

2) There's quite a chance that it might be closed (due to the flags ;) and my answer and time would be entirely wasted.

skullpatrol

yup, the OP needs to show some effort.

Q: Where does the phrase "crazy like a fox" originate?

If you say that someone is "crazy like a fox", it means that their behavior appears to be insane or nonsensical at first glance, but there's actually something very clever and subtle to it that's working toward their interests in unexpected ways. Where does this phrase come from? What do foxes ...

@Knight That song is kind of a tribute to Syd Barrett. It has nothing to do with the expression "crazy like a fox".

Johan Liebert

@FakeMod I need some mathjax help.

PM 2Ring

Syd was a co-founder of Pink Floyd, and wrote most of the songs on their first album. But he became very erratic and his mental health deteriorated so badly that they had to kick him out of the band. Some say he developed schizophrenia, or "acid psychosis", but he was never given a formal diagnosis.

@FakeMod though they look in good condition when using desktop mode.

@PM2Ring I like Time by Pink Floyd. The guitar solo in the end is super awesome!!

@JohanLiebert get ready to approve my edit before the reviewers reject it...

user434058

@JohanLiebert I don't know how to align the equations which have text in between them....

PM 2Ring

12:36 PM

@FakeMod It is good. But if you've never heard it before, you must listen to Echoes. It's rather long: it was the entire 2nd side on the Meddle LP.

Johan Liebert

@FakeMod approved though in mobile version it still doesn't look different.

user434058

@PM2Ring Will surely check that out. I also like Another Brick In the Wall (Pt. 2) by them..

user434058

@JohanLiebert Anyways aligning shouldn't be taken very seriously. I only use aligning when I want to skip writing the LHS everytime

PM 2Ring

@FakeMod For a little while in the early 1980s, I used Pink Floyd's Time for my alarm clock. I plugged my record player into a timer socket. But I got sick of it after a couple of weeks. :)

When you listen to Echoes you will hear many themes that resurfaced in their later material.

Johan Liebert

@FakeMod anyways since most users use desktop site therefore they won't have any problem with it.

user434058

12:43 PM

@PM2Ring Actually I used to go to music classes. All the people there wer Pink Floyd fans. Like my classes had Pink Floyd's symbol painted on the walls. And posters stuck on the wall. They were rock fans. But I was an electronic music guy. But yeah, my teachers there influenced me quite a lot. They hold the credit for the only few rock songs that I like.

PM 2Ring

@YuvrajSingh... Sort of. Bur spacetime geometry is strange inside event horizons, and our normal intuitions about space and time don't work very well there.

user434058

@PM2Ring Hahaha :)

user434058

@PM2Ring as I said I haven't listened to much rock.

skullpatrol

user434058

@JohanLiebert Yeah. I use and am using a tablet. So it's equivalent to a desktop site for me.

skullpatrol

12:46 PM

::tablets rock::

user434058

@PM2Ring And even in that little rock that I have heard, most of it is pop rock.. So I don't really see me as a rock fan :)

user434058

@skullpatrol They surely do ;)

user434058

@PM2Ring Have you heard Midnight City by M83? Or for that matter, anyone else has heard it?

user434058

That's one of the oldest electronic music kinda stuff that I listen to..... So there might be people who can relate to it!

PM 2Ring

@FakeMod Understood. However, many early electronic music creators were influenced by Pink Floyd. And of course Floyd were using synthesizers when they were still new technology. One early electronic music group I used to listen to a bit when I was younger was the German group Tangerine Dream. They were a huge influence on the early electronic music scene.

user434058

12:51 PM

@PM2Ring Yesterday, Sir John Rennie (or Rockstar Rennie? no offense!) recommended me Tangerine Dream. You can see the conversation in General Chat!! I am planning to listen a lot of Tangerine Dream stuff tonight!!

user434058

@PM2Ring Almost all the good musicians were good because they tried new stuff and that new stuff was often mind-blowing.

Johan Liebert

@FakeMod that Olympia question is getting a lot of positive response. Personally I hate such behavior as people are distinguishing the a homework question on the basis of its origin (And guess what answered have given almost complete solution, he/she now just have to do math).

I think it would reach HNQ soon.

Roaring Twenties

The Roaring Twenties refers to the decade of the 1920s in Western society and Western culture. It was a period of economic prosperity with a distinctive cultural edge in the United States and Europe, particularly in major cities such as Berlin, Chicago, London, Los Angeles, New York City, Paris, and Sydney. In France, the decade was known as the "années folles" ('crazy years'), emphasizing the era's social, artistic and cultural dynamism. Jazz blossomed, the flapper redefined the modern look for British and American women, and Art Deco peaked. Not everything roared: in the wake of the patriotism...

are back!

:D

user434058

@JohanLiebert Yeah!! But don't worry! Try to do what you can do to help the site and the rest is the community's responsibility. I am not asking you to suppress the question by downvoting it and neither have I downnvoted it. But stop worrying about SE. It is a big site. 1 or 2 hot HW questions won't make a big difference. Enjoy your time on this site!

PM 2Ring

@FakeMod I just watched the official video. It's ok, and I quite liked the video, but the drumming in that song is a bit too "pop music-ish" for my taste. Here's an example of the kind of electronic music that I enjoy: Dissolved Girl, by Massive Attack.

@FakeMod :) I suspect that John Rennie & I have a big overlap in musical tastes. Which kind of makes sense, since we're roughly the same age.

user434058

1:09 PM

@PM2Ring Initially I was not fascinated by the song. But one day, my class test had gone bad and it was quite late night and I had started my playlist with the shuffle feature on. And suddenly that song played. At the moment when the end played (that saxophone), I felt like sleeping, floating and sinking into something divine. And since that day I can relate the song to that feeling and thus I like it.

user434058

@PM2Ring I would recommend you to re-listen the end with nice earphones or headphones on and imagine being lost in the vast universe. I really like that feeling.... :)

@PM2Ring Yup... I am 16 so we might have very different choices :)

I suppose you'd have VTCed it.

user434058

@AaronStevens Is it okay to downvote a question just to stop it from being a HNQ?

Aaron Stevens

@FakeMod Down votes should be given if you think the question is of poor quality, not useful to the site, etc.

1:28 PM

@FakeMod Of course. OTOH, I have a nephew who's a year or 2 older than you, and he likes a lot of the guitar music that I like.

user434058

@AaronStevens So I suppose HW HNQ's are not useful or even harmful??

Aaron Stevens

@FakeMod HW questions are not always bad, and some can make for good HNQ questions. However this one does not. The site is not a homework help site. So just posting a question saying "I couldn't solve it" is off topic

user434058

@PM2Ring I just finished listening Dissolved Girl. The intro (about first 30 secs) made me feel as if I was to encounter a new song to be favorit'ed. But the rest of the song took quite unpredictable turns (for me) and did not turn out the way I expected.

user434058

@AaronStevens I agree!

PM 2Ring

@FakeMod Mods can remove questions from the HNQ list. If you have a good reason to believe that a question should not go onto the HNQ, you can flag it with a custom flag. But you must give a solid convincing argument stating why.

@FakeMod Oh, ok. I like a bit of unpredictability in my music, but I agree that it can be disappointing when songs go in directions that you don't agree with.

user434058

1:34 PM

@PM2Ring and @JohnRennie If you like some mixture of electronic and rock music, then try checking out Heavyweight by Infected Mushroom. I bet you would like it. Especially the solo in the end.

user434058

@PM2Ring evryone has a different sense of unpredictability. Due to the sugary pop music famous nowadays, people are starting to listen more and more predictable music. So the non mainstream genres aren't appreciated much by the majority. That's what I think.

user434058

@PM2Ring Well I don't think that the question is really so bad that it shouldn't be given the opportunity to be a HNQ. And I do not have any solid convincing argument to support the stoppage of it becoming a HNQ.

PM 2Ring

@FakeMod Yeah. I have a fairly low tolerance for most modern pop music. I listen to a lot of music, but I haven't listened to much commercial radio for over 20 years.

user434058

@PM2Ring But I do have came across a few good songs but that was from a show which focused on non mainstream electronic music.

@skullpatrol But whenever I listen that song it seems to me as if Roger Waters is talking to me personally. Do you feel that too?

skullpatrol

Sometimes, music is that way.
