The comparison is a process that makes human beings to identify by sensory analysis different aspects related or between two or more objects. Its main foundation is to detail the similarities or differences that present elements with a certain simile, since it is illogical to make a comparison between two things that have nothing in common. The comparison can be defined from a very technical point of view, however we have clear ideas that it is an everyday term part of the day to day.
An experimental comparison is made through the process of observing the reactions of each of the elements involved. For example, in chemistry this study medium is used as a tool to observe the response of chemical elements to their interactions.. In general, laboratories have already tested most of the reactions between the elements, however, at the study level, incognito and comparative parameters are maintained in order to proceed with a more practical than theoretical teaching. The comparison in the various areas in which it is applied is aimed at the interaction of the human being with the environment that surrounds him. In the concept of simile we were talking about the fact that the response of the human being in the presence of two or more elements whose characteristics correspond even when they have a certain similarity is automatic, that gives us the idea of also applying the same reference when we talk about a comparison.
The reason why a person compares one thing with another is diverse and goes according to the need they present at that time. If a woman is in the aisles of a supermarket, it is by comparing the prices of the product she is looking for, she is automatically making a relationship between the price and the quality of the product, then the comparative analysis goes beyond what is initially had naked eye. The comparison at a certain point can become rhetoric, this figure that concerns the speaker but tries not to be interpreted exactly as his words indicate, seeks to make a subliminal comparison, in a way, becoming inexpressive of the truth.
