Thought experiment regarding an object approaching a mirror The entire point of relativity is that c + v = relative velocity is completely wrong. Superman will always see light coming towards him at c. |

Why does kinetic energy increase quadratically, not linearly, with speed? +1 for arguments of homogeneity and isotropy |

Isn't the uncertainty principle just non-fundamental limitations in our current technology that could be removed in a more advanced civilization? Uncertainty can be described in terms of commutation relations. This may not be an answer you're looking for, but it's a pointer that it exists in the maths if you start looking for it. |

Work Done by Rockets in Orbital Motion I figured an integral here would be too much detail for the required answer. And it doesn't really matter for such a simple potential. |

Work Done by Rockets in Orbital Motion Hmm... I suppose a $g_{eff}$ would be more appropriate... |

Does Polytetrafluoroethylene (Teflon) have low wind resistance? I see. The short answer, I suppose, is no. At least not necessarily. Friction is due to microscopic factors while resistance in a fluid is mainly due to macroscopic factors. |

Why are alpha particles made of 2 protons and neutrons? Because "isospin" and "spin singlet" requires a good bit of background knowledge. This graph gets the point across much more effectively. |
