What is the origin of flavor? @DavidZaslavsky: Actually, I am asking the same question again. Let me justify it: The first time around, the question was misunderstood by everyone, probably because I wasn't clear enough. I wanted to correct the question, but then the (otherwise fine) answers didn't match anymore, and I was asked to open a new topic with my actual question. I guess the best thing would be to reformulate the other question to match it's answers (I'll be glad if you have any suggestions on how), and to reopen this as my actual intended question. |

To which extent is general relativity a gauge theory? @namewhere: No, what I meant was more along the lines of what Murod Abdukhakimov posted, namely that the metric connection shows up in the covariant derivative in the same way as the gauge field would. |

To which extent is general relativity a gauge theory? I faintly remember that there is a nice way to think about GR as a gauge theory (or gauge theories as geometry), and it had to do with viewing the Levi-Civita connection as a gauge field. Unfortunately I don't know enough GR to write down the argument. |

How do I calculate the probability that the oscillator is in a certain state using partition function? cleaned up the latex a bit |

Expressions for canonical partition function and probabilities $p(E_i)$ If your asking questions related to your homework, you should include a bit more on what you already tried and where exactly you're stuck. Try to show some effort, people don't like doing the work for you :-). If you just need the definitions, look here: en.wikipedia.org/wiki/…, it should be easy to solve then. |

How do I calculate the probability that the oscillator is in a certain state using partition function? Hi abcXYZ, and welcome to Physics.SE! If you want to, you can use LaTeX code in your question to make the formulas more readable: \$ x^2 \$ becomes $ x^2 $ |

What is the origin of flavor? @dmckee: I want to know how people are trying to explain the origin of flavor. i.e. the conserved thing that makes muons different from electrons. Can it be a broken symmetry? Substructure? That's what I tried to ask both times. However, the other question was universally misinterpreted as something like "why three generations? (how do we know the fact, and what phenomena depend on it?)". |

Origin of lepton/quark generations? @Anixx: I didn't mean to ask about the number of generations. I know that answer, besides, it was already handled before here: physics.stackexchange.com/q/2051/825 . I opened a new, clarified question here: physics.stackexchange.com/q/46097/825 |

What is the origin of flavor? @AndreHolzner: Right. It seems that flavor is something fundamental and real, and thus a better theory might explain it. "Oh, that's a manifestation of the XYZ symmetry.". It might as well go away as a fundamental concept, like nuclear isospin, when a new theory comes along. I'm just looking for either kind of theory here. Some brilliant theorist must have thought of some crazy theory to explain this, they always do :-) |

Origin of lepton/quark generations? @user1504 OK, a second try :-) physics.stackexchange.com/questions/46097/… . Should we change this question to match its answers better? |

Origin of lepton/quark generations? Well, I explicity asked for current theories explaining the "generation" phenomenon, and I explicitly said I wasn't interested where the number "3" comes from. I'm surprized this got so misinterpreted... but you're probably right |
