Rodney A. Brooks Quote
Quanta of force fields can even overlap each other and yet maintain their separate identities. Each field quantum lives and dies a life and death of its own. For example, a quantum of the EM field can be emitted from an atom in the sun, travel through millions of miles of space, spreading out as it goes, and then interact as a single unit with an atom in your eye.
