Since Ron Maimon has been driven away (by external SE forces against the will of the then on Physics SE active community) at the beginning of December 2012 and many other experts have left too, this is no longer the reasonably high level Physics.SE of physicists and physics enthusiasts I loved, enjoyed, and appreciated during almost two years. The site has been taken over by MO/MSO people and other non physicists who dominate the site and determine the rules of the game now.
Apart from the striking downgrading of the physics level (sporadic higher level questions about advanced topics get no longer answered and sometimes even downvoted!) and the fact that fundamental physics topics I am interested in have disappeared, too many very bad things, which should not occur on a serious physics site that upholds the scientific integrity, are now happening on Physics SE on a regular basis. The dominant people in power being very cynical and interested only in policying and enforcing detrimental and harmful rules and constraints destroys the usefulness of this site for people seriously interested in learning physics at a technical level, prevents the site from recovering from the heavy blow it had to take at December 2012, and drives academics, active researchers and students of physics and astronomy away.
Observing all these things going wrong is very painful and unhealthy for me. Whithout the SE owners, stuff, and moderators relaxing the firm stranglehold they impose on noncomputer sites too, by enforcing harmful network wide external rules and policies, Physics SE will never fully make use of its large potential to be a great place for researchers, academics, students, and enthusiasts to enjoy and learn physics together in a free and unrestricted by bureaucratic obstructions way.

How to find outflow pressure/force of air through a pipe Probably the application of the relevant version of the Continuity equation (which is the statement of mass conservation in fluid-dynamics) could help. |

calculate distance in feet using time interval from iphone camera Your use of the tags is quite inappropriate. This question has nothing to do with particle or mathematical physics... |

Einstein Field Equations in other space-time dimensions than 3+1? I've heard that there should be no gravitational waves in 2D |

Quantum field theory quote @Lee and you can ask Prof. Strassler questions too, he answers very nicely and patiently. His site is mainly devoted to explain particle physics to laypeople, whereas Physics SE is rather for learning physics at a technical level. |

Starting examples of Maldacena duality @CrazyBudy The sentence you edited out mentions a famous paper and the OP says he is not interested in getting this as an answer. So that sentence should not be edited out, even though user6818 could have edited the link in there too. So I rolled back to v1. |

What is the meaning of the concepts of “operator mixing” (and anomalous dimensions) @MitchellPorter (and others) I have asked on meta if it can be reopend. Maybe you can post your thoughts there too. |

What is the meaning of the concepts of “operator mixing” (and anomalous dimensions) @DavidZaslavsky as Mitchell Porter explains the question, it seems more coherent as I was able to see first. Asking about two nearly related concepts, giving an example of what one wants to better understand from knowing these concepts, plus investigating if these two concepts are known under other terms too, is legitimate and makes a lot o sense to me too. So can the question be reopend as it is, I think it should? We did just not understand it, but Michell Porter does and maybe he can even write an answer. |

What is the meaning of the concepts of “operator mixing” (and anomalous dimensions) @MitchellPorter I agree that in my opinion the question is not that bad as it is at present. So maybe you can "flag to reopen" by explainig in the textbox of the "it needs moderator attention" option why it should be reopend? I already did this. Maybe we can gain 5 flags to reopen ... ;-) |

What is the meaning of the concepts of “operator mixing” (and anomalous dimensions) @DavidZaslavsky ok thanks for this helpful comment, agreed :-). So now it is user6818's turn to clarify further and/or make multiple nice questions out of this one. I have seen he is still active here. |

What is the meaning of the concepts of “operator mixing” (and anomalous dimensions) @DavidZaslavski In addition, it would be helpful to leave a comment for the OP about what is wrong with this generally nice higher level question and how he can fix it. The question is certainly not less salvagable than the many homework questions we get and worth a comment about why it is closed ... |

What is the meaning of the concepts of “operator mixing” (and anomalous dimensions) @DavidZaslavsky I edited the question to focus on the physics concepts of interest rather than references. Can it be reopend? BTW since in this conctext, the concepts of "operator mixing" and anomalous dimension are very closely related, it does not hurt that the OP asks about them simultaneously in one question. So this should not be a close reason either in this case. |

Under what conditions are the renormalization group equations “reversible”? Hm, I am not sure if I understand that completely. Does this mean, that in order to be able to go backward and forward, the number of couplings in the theory or relevant operators should not change? |
