Slightly OT, but I remember doing the Santa FE Institute's online courses on Complexity and finding them to be very solid on the topic https://www.complexityexplorer.org/courses
she seems an amazing educator, check out her 12 min intro: https://m.youtube.com/watch?v=MizhVorgywY
don't know how long she worked on that script (conveying the idea first, details later). it's the first time I really understood the basics of linear dynamics. super impressive.
btw all of their videos are hosted on YouTube.
