  Lecture notes for 8 lectures on the `Physics of Lyman alpha Radiative
Transfer', given at the 46th Saas-Fee winter school held in Les Diablerets,
Switzerland on March 13-19 2016. These lectures aimed at offering basic
insights into Lyman alpha (Lya) radiative processes including emission
processes and Lya radiative transfer, and highlighting some of the physics
associated with these processes. The notes include derivations in greater
detail than what was discussed during the lectures.
