When I was young, my first real experience with this was seeing a black and white spiral optical illusion in a museum. I stared at it for a bit, and then my brain adjusted and when I looked away, it affected what I looked at.
I think my realization was that my brain didn't just do simple things, it did complex in many dimensions to adapt and fix things.
The same thing goes with your foot, and it goes way deeper than we realize. It's probably not that one muscle, it is ALL the muscles in the area working together to help you walk. I wouldn't be surprised if there are 50 muscles involved.
That's true of so many things isn't? At my graduation (EE as well as CS, is why it's relevant) I said to my dad that I'm still completely baffled by the simplest AM radio, forget WiFi.
I understand it (especially then), but it's just crazy isn't it, that it actually works? Discovering/theorising and then prototyping some of this fundamental stuff and seeing that for the first time must have been absolutely incredible.
