That it is the complexity?

It is the quality of what is made up of diverse elements.

Complexity is the group of unyielding qualitative properties of a phenomenon or process, natural or human. Expert, the complexity doesn't oppose this way herself to the simplicity (yes, to the simplification) since this becomes a case limit of that, what has deep consequences particularly on the human being's image.

A complex system is compound for several interconnected parts or crisscross whose bonds contain additional and hidden information to the observer. As a result of the interactions among elements, new properties that cannot be explained starting from the properties of the isolated elements arise. This properties are denominated emergent properties.

All our life is surrounded of complexity, The concept of complexity has several forms of to understand each other and to be defined the definition of complexity it depends on the observer's point of view something that is complex for the observer perhaps it is not it for another observer.

Key words: Complexity, elements.
