I was thinking about this amazing lecture series which I watched several years ago, and I figured that quite a few people here would find it interesting.
It is about getting information on the solutions of hard differential equations, using perturbation methods. Basic knowledge on differential equations and complex functions should be enough to feel reasonably comfortable.

The videos are also available on YouTube.
