Did You Know?

Aku ke satu website. Ini yang aku dapat.

"We know, there are known knowns; there are things we know we know. We also know there are known unknowns; that is to say we know there are some things we do not know. But there are also unknown unknowns -- the ones we don't know we don't know.
-Ronald Rumfeld-
