Technical detail in the solution of the hydrogen atom Oh, thanks, I managed to solve the rest of the exercise after reading your comment! |

Technical detail in the solution of the hydrogen atom It's supposed to mean "the function that maps $\mathbf r$ to $\frac{1}{r}$" but I thought the exercise was being too pedantic with the notation so I edited the original post to remove it and make it clearer. |

What is a photon's speed inside a dieletric? But from what I understand, an EM wave is a collection of zillions of "coherent" photons, which people generally explain to mean they are all "synched" (I'm not sure this is correct?). When a photon is absorbed by an atom, wouldn't it be later re-emitted at a random direction? And if all photons are being re-emitted at random directions, wouldn't this break the coherence and destroy the EM wave? |

What is a photon's speed inside a dieletric? @Qmechanic The top answer to that question simply says that the apparent speed of light is lower due to nebulous "interactions [of the photons] with the atoms of the materials". "Interactions" can be anything. Are we talking about collisions like in the Drude model? Or do the photons get absorbed, then re-irradiated? Or something else altogether? |

Amount of thermal energy in the Earth? @joshphysics I thought about that, but I don't know how to calculate the mass of the mantle, outer core and inner core. I could use a state equation (we do know the volume, temperature and pressure) but I have zero idea what state equation to use for molten stuff under huge pressures and temperatures. |
