@fasterthanlight consider that this is a *resource-request question* and that these two documents are long (50 & 27 pages) and quite dense. Is it really practical to try to find some small bit of each one to quote here that could at all improve the answer? I think in this particular case the answer is fine as-is.

For n-body simulation, you'll need some differential equations knowledge.  I can't recommend the Udacity "Differential equations in action" enough.  One of the first assignments is a gravitational slingshot.  And several n-body problems further in. https://www.classcentral.com/course/udacity-differential-equations-in-action-456

# How to locate helpful and instructive books and resources about numerical methods in cosmology?

(Asked by: username_0 on 2021-07-13)

I am interested in the hydrodynamical and N-body simulations, and I want to use simulation results to examine the theoretical models.

Hence I am searching for some helpful and instructive books and lectures for learning relevant numerical methods, such as:

* cloud-in-cell interpolation scheme
* the process of calculating the power spectrum
* data visualization

and similar. How might I best find resources like these?
