Question

Request questions from sites on the StackExchange networks that are on-topic here too, to be imported here. Moderators may then import the question.

Addendum

This thread can not only be used to request importing single questions, but PhysicsOverflow members who like some or all of their (for PhysicsOverflow on topic) SE posts imported can say so in a corresponding answer here too. Any other specific list of questions is fine too.

Comments

@RonMaimon I agree, but hide, not delete (delete erases from the database itself).  

@Dilaton On SE, answers can be ordered by time if one needs to, but not here.  

---

@RonMaimon hiding is ok But concerning references and study material (concerning advanced topics) they newer cluttered any site on SE (not the ones I was interested in) so they will not here either. They were considered legitimate in TP.SE and they are not forbidden on MathOverflow. So please dont introduce this for (advanced) students and people who want to learn about a new topic obstructive SE point of view (in SE they always said you can ask in chat which means forget about it because there are no physics people in chat)

---

ok, but the point is that it shouldn't come with rep, and it's extremely easy to do, and it only needs to be done once in each topic, so perhaps when reviews are up, it can be done in reviews. You can ask the same question on each topic, I think it's best to make a literature review for each tag on reviews, so that each topic has a set of references people can add to. It's just not effort to find literature.

---

@Ron Maimon what do you mean exactly by "the post disappeared"?! I hope there's no auto-deletion in Q2A core, like there is on SE.  

---

I meant it moved to a random position in the questions list, it wasn't bumped anymore.

---

Nah, I think we do not (yet) have to start deleting, this and the community moderation threads can naturally get pretty long, but I conjecture that thethe number of answers can get large but it should stay finite ...

---

Ok, hid them. If you find this annoying, unhide. I still think book recommendations belongs in meta, it will clutter up the main site. (I unhid them myself, as it caused the question to disappear for lack of activity)

Answer 1

[IMPORTED] 

Should we import this?

http://physics.stackexchange.com/questions/12175/book-recommendations

Comments

Maybe import it into meta. We can do book recommendations on meta, in lieu of community wiki.

Answer 2

[IMPORTED] 

Should this be imported? 

http://physics.stackexchange.com/questions/75006/what-different-approximations-yield-gravitoelectromagnetism-and-weak-field-einst ;

Comments

I think it should; even though GEM is an approximation to GR, it should be on-topic because it can be used for approximating Gravitational Waves, and so on.   

---

Yep, it is a nice question.

Answer 3

[IMPORTED]  

I have a list of research-level and interesting questions in physics SE

http://physics.stackexchange.com/users/9444/xiao-gang-wen?tab=favorites

I hope they can be imported to PO.

Also the question taged by "topological order" in physics SE can be imported into PO.

Comments

Oh yes, thanks for suggesting this nice list !

---

Thank you very much.

---

Phew, about 30 questions left to import. Tomorrow (Indian time), I will start with "What's vison in Z2 resonating valence bond (RVB) state?" 

---

All imported! Yay! Thank you for this great list!   

---

Thank you very much for the great effort!

---

First two pages of your favourites are done, three more pages remaining.     

---

Ok, imported about 3 pages of questions. Two pages (Actually one and a half) remaining. 

Answer 4

[IMPORTED]  

I hope these questions can be imported, because I would like to get more satisfactory answers (if possible):

http://physics.stackexchange.com/questions/104422/question-about-the-noether-charge-algebra

http://physics.stackexchange.com/questions/72815/large-and-small-gauge-transformations

http://physics.stackexchange.com/questions/100597/how-do-we-know-for-sure-a-theory-is-non-renormalizable

Comments

Imported.  

---

Thanks!

Answer 5

[IMPORTED]  

Can these questions be imported?

Comments

Oh yes, they are nice! There is currently a (technical?) issue with importinging questions but we are looking at it and will import them as soon as possible.

---

Thanks. I noticed that the imported questions will not appear on the first page, probably because the post date is too long ago. I'm wondering if I can bump up some of them to the first page, because for example the unanswered ones can essentially be taken as new questions. @dilaton

---

Yes, as they are nice I think nobody should feel picked if you edit them for example or add a comment, which would make them appear in the "All Activity" list ...

I personally always disagreed with the people who complained on SE about very good old questions getting bumped by edits, since this rather improved the front page ...

---

Hi @Dilaton, I noticed that the landing page (http://www.physicsoverflow.org/) is not exactly the same as the Q&A page(http://www.physicsoverflow.org//activity/main), for example I bumped up this question, but it only shows up in Q&A, not the landing page. Is it just the way it's supposed to be or is it a mistake in design?

---

@JiaYiyang It appears in the /activity page, which most people check too. 

---

@dimension10: thanks for the clarification, though I'm not sure if "activity" is users' default option. Before your reply I was only cliking our big "physicsoverflow" logo for updates, which led me to the landing page. 

---

@dimension10,@Dilaton: Now I am afraid my concern needs to be taken more seriously, you can compare the number of views of questions that appear on first page of main landing page with the first page of Q&A(of course compare the posts that were triggered into "recent activity" at about the same time). there is a huge dismatch .

---

I think this is worthy of a separate meta post.

Answer 6

[IMPORTED]  

Please import the following questions (asked by me) from Physics Stack Exchange. (Not all of my questions there are suitable here, but I think these ones all are, and I'd like to have them here.)

By the way, once they're imported I can edit them etc., right?

How do I import stuff? I can make a similar list again today, and I don't want to make work for others.

---

@Ron Maimon Ok, just gave admins permission to import. Use the "Import SE-Question" button in the white navbar.   

---

I just imported all graduate-questions on PSE since 4 April, so I will assume these are all imported.

I just imported all graduate-questions on PSE since 4 April, so I will assume these are all imported. If you find that any of them are not imported, you can always import them yourself.  

Answer 9

[IMPORTED]  

Could you import the following questions where I gave some contribution (asking or answering).  I think they are not of basic level  and interesting questions in physics SE.

Comments

WOW, I think we all (all three of us) saw this post quite a while ago, but decided to import them all at the same time, just deleted the duplicates. It would be a huge joke if we double-deleted them too.  

---

@Ron Maimon By the way, the third one had actually been imported a long time ago, yet you re-imported them. Please remember to check if a question is already imported before importing. Thanks!  

---

To avoid this keystone cops moment, I think it would be best to add "imported" to the top of the post before actually importing the questions.

---

@Ron Maimon That's fine for these small import tasks, but what about BIG ones, like Xiao-Gang Wen's?   

---

You start it, you finish it.

---

Oh no! Doubly imported... I just did it too.

---

@Ron Maimon I know, but my point is that one may take a few days to finish it, and by marking as "[IMPORTED]", users may get confused that we have already imported the posts.
