Second for this! They're great and a fun watch :)

What were you simulating and with what method? :)

Also, Balakrishnan's lecture series "Selected Topics in Mathematical Physics" begins with the most careful exposition of complex analysis I've ever seen aimed towards physicists in about ten lectures. I've never watched beyond that, but I'm told the rest is excellent ^^.

Helo ^^. One of my favourites is Carl Bender's lectures on mathematical physics. He introduces a bunch of powerful tools for making (non-numerical) headway with problems that do not have closed form solutions (perturbation theory, WKB, multiple scales, etc). It's a really fun watch :).

This was one of the first books I read after moving to the West of Scotland back in 2015. :)
