Perturbation Theory is an important and powerful method in physics. It enables us to make progress when a physical system is too complicated to be analyzed exactly. The essential idea is to solve the behavior in steps. First we approximate the system by some simple Hamiltonian whose Schrödinger equation we know how to solve. Then we add the bit missed out, and use perturbation theory to calculate how our previous results (energy . Q3oItpVa9fs. Cymatics. https://youtu.be/. WMnRxFDVw0g. Julius Sumner Miller and Sound.
