Why is the (nonrelativistic) stress tensor linear and symmetric? The stress tensor is a function a given $n$ to $T(n)$. The equality you are describing refers to integration over a surface $S$ with varying $n$s. How from that equation over general $n$s I get some reasoning about a given $n$? Thanks! |

Why is the (nonrelativistic) stress tensor linear and symmetric? I like the method in this answer, but still missing some details. In the first part, is there implicit summation over $j$? More importantly, a volume element with surface $S$ has a changing $n$; how does the stress tensor enter this calculation? |

Good book for Analytical Mechanics This book explicitly deals with differential geometry, which I would like to avoid. |

Photon hitting an atom with higher energy than needed to ionize So will the photon be absorbed completely and the electron will have the excessive energy (as kinetic energy)? |
