I’ve heard the following multiple times from different people, mostly in regards to other engineering and science fields. I can’t speak to how effective it is personally, though.

It roughly boils down to find a good degree program in subject and try to get information on the curriculum, books involved, etc. and follow it on your own.

Assuming this is all for personal reasons, as there’s no way you’re getting into these fields without having paid up.

Yes, it's simply for the sake of curiosity, and I don't intend to getting into these fields. My goal is to bring some structure in my learning, because currently I just pick a book here, a book there, and that doesn't feel very effective.

I guess looking at the curricula of some good degree programs is the way to go.
