No, they did not. They *thought* that the world was flat, but they didn't *define* flatness as being "the shape of the world." It looks pretty clear to me that you don't understand what a definition is. A definition is a statement about a word and what it means. It's not a statement about the world; it's a statement about a word!

No, I don't think that's what we do at all. Physics is about reality; math is about numbers. They are not the same.
