The Hydrogen Atom, Part 1 of 3: Intro to Quantum Physics

The first of a three-part adventure into the Hydrogen Atom. I'm uploading these in three parts, so that I can include your feedback in the videos as we go along. Sort of like in a lecture when they stop and ask "Does anyone have any questions?". So please let me know if you have questions! :) Part 2 will solve the Schrodinger equation, deriving the energy eigenstates and eigenvalues. Then we'll look at the hydrogen spectrum and see how these ideas make contact with experiment. Part 3 will go beyond Schrodinger, exploring how the Dirac equation relates to hydrogen and provides a natural explanation for spin (and a nice prediction of antimatter, too), and then we'll look at the Lamb shift and talk briefly about quantum electrodynamics.
