Errors

I've learned that everything is full of errors and mistakes.
I've learned that we should see anything with it's errors.
Everything like a point with a error ellipse surrounded it and the point can replace in ellipse that we can not remove.I mean everything that you can show it by number and either not by number.
Nothing in this world is absolute correct, we live in here so we live within mistakes, so even when you think you do it correct you're absolutely wrong.
I'm not sure but i think there is nothing that we can do it completely correct, with no any mistake or error.
I'm not sure because only thing that I've not had doubt about is math!
