I’ll mention a few YouTube channels that have quite a large following, but maybe some people aren’t aware of them:
Kurzgesagt has animated videos on a variety of real-world problems, theories, etc.
Grant Sanderson’s 3Blue1Brown describes math concepts and related topics with animations and visualizations from a perspective of how you could “re-derive” / “re-invent” them yourself.
Ben Eater explains fundamentals of electronics, computers, CPUs, and other related topics.
