comment Is it possible to affect the trajectory of a black hole?
You are right. The black hole, like any object with mass, conserve the linear and angular momentum in absence of external forces and torques.

comment What prevents an atom's electrons from “collapsing” onto its protons?
I'd say that is because the energy is "quantized". The electron's energy can't have any value, it can only have a multiple of the elementary energy $h \nu$.

comment Radial Wave Function for Spherical Squared Well Potential and $S$-Matrix
@Trimok you are right! Could you please write this as an answer so I can choose it like the best answer. Also, could you suggest me a basic book (bachelors level) where I can find more about the $S$-Matrix (or "$S$-Function") in this context, please?

comment Equations of motion for a pendulum in 3D?
All seems good. Just a question, where is $ \dot \theta$ in the last expression?
