System: In the scientific field, any object of study that, although constituted by different elements that are mutually interconnected and interacting with each other and with the external environment, reacts or evolves as a whole, with its own general laws. A set of closely coordinated abstract or conceptual entities, even if not necessarily dependent on one another. It is a choreography for bodies that act in a vast space, determine alliances, relate to geometric areas, using it as a force of displacement.
