Light orbiting a massive body Thank you, much clearer than the answer of the duplicate. |

accepted | How is Gauss' Law (integral form) arrived at from Coulomb's Law, and how is the differential form arrived at from that? |

How is Gauss' Law (integral form) arrived at from Coulomb's Law, and how is the differential form arrived at from that? Is 3 Poisson's equation, a generalisation of it or a subdivision of it? And thanks for the answer- not too unfathomable. |

In what way do Cooper pairs of electrons bond and stay bonded in superconductors? Excellent, thanks so much for your time. |

In what way do Cooper pairs of electrons bond and stay bonded in superconductors? And, remembering the forgotten, why do some materials' electrons condense at higher temperatures (or: what mechanism DO they use, then, if not a BEC, to superconduct?)? |

In what way do Cooper pairs of electrons bond and stay bonded in superconductors? I have, bar the mathematics, understood that far. But what stops the electrons from doing this at relatively high temperatures (i.e. forgetting high temperature superconductors)? It can't just be the disruptive thermal motions, as not all materials superconduct. Or are the electrons which demonstrate this effect in the conduction band beforehand in superconducting materials, even when hot, and just need to have the thermal motion removed to begin condensing? |

In what way do Cooper pairs of electrons bond and stay bonded in superconductors? You truly have overestimated my aptitude, yet thanks, however, for the bits that I could understand. |

In what way do Cooper pairs of electrons bond and stay bonded in superconductors? How do they actually 'stick together', though? Is it essentially the way that all BEC stick together, and I need to read into it more? |

Why do hydrogen atoms attract? Thanks for that- but also- why is it more stable (or with less potential energy, same thing)? |

Why is the $\langle v_{x}^{2} \rangle=\frac{1}{3} \langle v^2 \rangle$? Because they don't cancel? Thank you both! |

Why is the $\langle v_{x}^{2} \rangle=\frac{1}{3} \langle v^2 \rangle$? I'm having trouble with $\left \langle v_x^2+v_y^2+v_z^2 \right \rangle=\left \langle v_x^2\right \rangle+\left \langle v_y^2\right \rangle+\left \langle v_z^2\right \rangle$, essentially |

Why is the $\langle v_{x}^{2} \rangle=\frac{1}{3} \langle v^2 \rangle$? Then why is $\left \langle v_x^2+v_y^2+v_z^2 \right \rangle=\left \langle3 v_x^2 \right \rangle=3\left \langle v_x^2 \right \rangle $? I could see why$\left \langle v_x^2\right \rangle+\left \langle v_y^2\right \rangle+\left \langle v_z^2\right \rangle=3\left \langle v_x^2 \right \rangle $, but not how this leads to the first equality. I'm probably being very slow, apologies. |
