https://physicstravelguide.com/ - Found this rather interesting, kind of like a multi-level wikipedia
For example each equation/concept section has various “views” to it - Intuitive, Concrete, Abstract, “Why is it interesting?“, Research, Definitions, FAQ, History. This gives a much more holistic view of things as compared to what wikipedia provides today. I find this much more learner friendly as compared to current textbooks!
I don’t 😞 I might have something for math though.
The thing is finding good resources that are also structured well is rather hard. I’ve been on the lookout for such resources for the past two years - haven’t had much luck.
