Degenerate perturbation theory EXAMPLE: determining energy levels of infinite cubical well

In this video I will determine the first order corrections to the energy levels of the infinite cubical well utilizing perturbation theory. My name is Nick Heumann, I am a recently graduated physicist. I love to teach physics, so I decided to give YouTube a try. English is not my first language, but I hope that you can understand me well enough regardless.
