Filming light in motion? Good point, not a native English speaker, and automatic orthography correction didn't help me there :D It would be nice to have laser beans though... |

Surface terms for field path integrals? So the point here is that the "surface terms" vanish when I integrate with ${\cal L} \rightarrow (1+i \epsilon){\cal L}$, right? |

Surface terms for field path integrals? You are right @user1504, I edited it to include the essential formulas |

Why is the (free) neutron lifetime so long? @Terry - maybe you did (forget me) but I didn´t forget the question ;) Great answer by the way! My thanks to everyone involved |

Why is the (free) neutron lifetime so long? I not completely satisfied with the answer. It seems to me that dr-bdo-adams and @terry-bollinger are explaining this based on the off-shellness of the W. But still the diference is too big, the neutron lifetime is $10^9$ times bigger than that of the Muon, but the "liberated energy" is only $10^2$ smaller. Is this going like $\left(\frac{E_L}{M_W}\right)^4$? ($E_L$ is the liberated energy). Can someone give me pointers of why we have such a high power in the dependence? |

How to detect ice in thermostat Nice idea, but he would have to figure out a way to avoid ice formation in the tube itself, which could be hard depending on the setup. |
