A pattern that its not random is known mathematically as information.*

Information can also be defined as organization, or as coherence.*

Gregory Bateson has defined information as "differences that make a difference."*

* (If you know something already, or can predict it easily on the basis of what you do know, it is not information for you. Conversely, if you don't know something, or can't predict it, it is information.)

Information is also known mathematically as negative entropy or, in a widely used abbreviation, negentropy.
