∗ Numerical overview:

Here are some notes on numerical methods to help you with some of the computational parts of the assignments.

You may also want to look at the Numerical Methods for (Astro)Physics notes from the course I taught a few years ago (and will teach again next semester).

∗ Lecture schedule:

Note: the topics may shift a bit depending on our interests.
