I recommend Veritasium, his videos are quite good. This one probably has good and useful visualizations but I was doing the cleaning while listening to it so I missed that. Still possible to follow without watching though.

Absolutely. His "gravity is not a force" video led me through a whole range of emotions from "this is ridiculous" to "actually..." to "holy crap, I've been wrong about this my entire life".

In terms of sheer brain-breaking... this is my favourite: https://www.youtube.com/watch?v=ovJcsL7vyrk

But this is the one I think people on HN need to watch most https://www.youtube.com/watch?v=3LopI4YeC4I

Feigenbaum constant was definitely hardcoded

The gravity video was instrumental in me finally understanding years of physics classes.

And the YouTube algorithm was actually really useful and made discover this series of video on special relativity: https://youtube.com/playlist?list=PLoaVOjvkzQtyjhV55wZcdicAz...

Forces are just models to predict interactions between particles.

It's only a model (a very accurate one though) so nothing is "really" a force. They are not material objects. But for gravity, something even more accurate was found to model it.

In his earlier days I used to dislike Veritasium because I felt he relied too much on the "go out and ask random strangers about science" format too much. But over the last few years he's really upped his game and evolved the format to the point where I'm subscribed to his channel and get excited when I see a new video from him.
