The simulation is an act that is to imitate or pretend you are performing an action when in fact it is not carried out. A person or animal simulates to meet a certain goal. While it is true that human beings reason and have more reasons to pretend or simulate, animals of various species carry in their instincts an ability that allows them to pretend that they are part of an environment (hide) or play dead to preserve their lives. Its etymological origin confirms that what we want is to appear to be something else that we are not by simulating. It comes from the Latin "Similis" which means "Similar".
We see simulations everywhere in everyday life, the clearest examples we see on television, where 90% of the programs and films that are broadcast consist of and are composed of actors and scenarios in which stories that are not true or are simulated they are based on past events. The artists are in charge of recreating versions of an adapted script of events that are not real in novels, movies, television series, cartoons and "Augmented Reality" shows.
Simulation is applied in research fields such as chemistry, biology, mathematics and physics, comparative studies of elements of nature need experiments in which behavior is evaluated, the same happens in society and the everyday environment.
When simulation is a scientific method, a series of procedures and indications must be followed to comply with it: definition of the system, in which it is established which are the elements that must be simulated, including movements and relevant aspects. Formulation of the Model, the space in which the event or phenomenon occurs is created or imitated. Data Collection, at the end of the simulation process, we have the information of the process as if it were the original or at least the approximate one. Verification, comparison and verification of the data obtained in the simulation and the data of the original version. Interpretation, the data obtained is evaluated and used in order to verify that the data obtained are actually the desired ones. Documentation, scientists support the information obtained as saved data to serve as support for new generations of scientific experiments that continue the work.
