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.

@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]  

Could you import this? In my answer I gave a general idea on why observables in QM are generally unbounded operators. I think it is non-trivial and of general interest.

http://physics.stackexchange.com/questions/102476/self-adjoint-and-unbounded-operators-in-qm

I have checked, it is not already present here.

Done : )  

Answer 2

Some, in my opinion, interesting (graduate-level) question of Physics SE where I gave some contribution:

http://physics.stackexchange.com/questions/92549/the-most-general-procedure-for-quantization

http://physics.stackexchange.com/questions/96569/double-connectivity-of-so3-group-manifold

http://physics.stackexchange.com/questions/96045/idea-of-covering-group

I was not able to check if they are already present in PhysicsOverflow, sorry.

Nice posts, they didn't exist here yet. I have imported them now.

Hi Prathyush,

they are now here and here.

However, the second and third questions are basically two versions of the same question, the first from math SE, and the second from Physics SE.

The answer to the Physics SE question is more "popular", so I am not sure if we want to merge the questions to have both answers, or only keep the one from Math SE?

Maybe @Dimension10 and @ArnoldNeumaier can have a look at this too ...

---

@dimension10 I would say skip the physics import,If it were upto me. I actually wanted only the math one to be imported. However I added the physics one because some of the comments seems to be sensible.

@dimension10 I cant see how it is relevant to the question, In an case you imported it at that is just fine too.

---

Merged. I don't see what's so bad about the PSE answer.

---

@Dimension10 to me John Duffield s answer looks as if he has just skimmed through different sources that looked relevant to him to write a text appealing to non-expert readers.This procedure to compose answers about topics one is not personally knowledgeable about is widespread and supported on physics SE.

---

@Dilaton Oh yes, you're right - sorry. But those kinds of answers should be dealt with by downvoting, not sure what's the point of not importing.

Answer 6

Should this be imported?

Comments

Done.

Answer 7

[IMPORTED]

Should this be imported?

http://physics.stackexchange.com/questions/86833/how-to-understand-the-qed-qcd-and-standard-model-lagrangians

Comments

I think it should be imported. When I was only embarking on QFT, I spent  a huge amount of time trying to find a source to understand and derive these Lagrangians, I think we should provide resources on similar things, helping people who want to embark on a certain field.        

---

I don't think we should. Someone on a graduate program will know what the symbols mean.

---

@physicsnewbie I think the thread can be used to give a short explanation of QED/QCD.  

Answer 8

Should this be imported?

http://physics.stackexchange.com/questions/82573/a-gentle-introduction-to-cft

Comments

I think this should be imported. CFT is on the lower end of "graduate-level", as graduate encompasses anything beyond undergraduate, which includes masters level stuff, which quite often includes CFT.       

Answer 9

Should this be imported ?

http://physics.stackexchange.com/questions/77622/book-to-read-before-introduction-to-gauge-field-theory-by-bailin-and-love

Comments

This should be imported too, in my opinion, for the same reason as for the gentle intro to CFT question.  

Answer 10

Do we want to import this question?
