You are either in branch main or fall2022. The main branch is updated when fall2022 is ready for public view.
Here you will find the course materials used in PHY 415 at Michigan State University in the Fall of 2022 as taught by Danny Caballero. Future iterations of this course will appear in this repository but as different branches.
Once the main brnach is up-to-date, the course site is updated and posted as the gh-pages branch. That branch produces the public facing website.
