Something I find interesting, the number of people who think that if they can't understand a subject nobody can.

I think I saw that as a tag for one of our moderators.

I keeps seeing it applied to electricity, statements like "No one really understands how electricity works".

 

But isn't it true nobody knows what charge really is?

Point proved.

 

Interestingly charge is one of the few quantities in the physical universe unaffected by relativity transformations, unlike mass, length or time. More interestingly charge is not controlled by quantum considerations (uncertainty, quantum numbers) either, unlike momentum which is.
