As I learn more, I know less.

I just watched a YouTube video that states the more we learn, the more we find out what we don’t know.

Agnotology is the study of ignorance.
That was fun.
There is another approach that identifies specific things we can not know. Heisenberg’s uncertainty principle said that we could not know both the location of an electron and its momentum. That’s the first “can’t know” principle that I read about. I saw a list of similar principles, but I don’t remember them.
