Plot of electric potential inside a p-n junction for nonzero bias What the heck? What do you mean, not an actual physics question? Do you mean it's not a question or it's not about physics? |

Right Angle Circuitry I don't understand. I'm already familiar with the magnetic vector potential field, denoted A. The A field is not mysterious. |

Does the heat death of the universe really imply a maximum entropy state *all* of the time? Or most of the time? en.wikipedia.org/wiki/Boltzmann_brain |

Has every possible interaction between elementary particles been observed? The core of the Sun is over 10 million K, not 5800 K. Check your facts. |

How come an anti-reflective coating makes glass *more* transparent? This is what I was going to say. There is a superposition principle for amplitude, but not for power. The power can have interference, which is the case here. |

Solving one dimensional Schrodinger equation with finite difference method Except that if you solve this with any softening of the singularity, such as $1/\sqrt{x^2+a^2}$. you'll get a no-node ground state, and the energy of that state goes to $-\infty$ as $a$ goes to zero. NGY wants the one-node state to be the ground state, but for any softening of the singularity there is a no-node ground state. Only for $a=0$ does that no-node state not exist. |

Right Angle Circuitry If 2.) can work even though the only current passing through the loop is displacement current, then why can't 1.) work the same way? |
