Definition of theory - What it is, Meaning and Concept

The word theory has its origin in the Greek word theorein ( "observe" ).This term used to be used to mention to the visualization of a play, which may explain why, at present, the notion of theory makes it possible to refer to a provisional issue or that is not one hundred percent real.

Anyway, the historical evolution of the word allowed to give it a more intellectual sense and then began to apply to the ability to understand reality outside of sensitive experiences, from the assimilation of these experiences and their description by language medium.

At present, a theory is understood as a logical system that is established from observations, axioms and postulates, and pursues the purpose of affirming under what conditions certain assumptions will be carried out.For this, an explanation of the appropriate means is taken as a reference point so that the predictions can be developed.Based on these theories, it is possible to deduce or postulate other facts by certain rules and reasoning.

The theory of scientific dye , meanwhile, is based on the approach of a hypothetical-deductive abstract system , which sets a scientific description based on a set of observations or experiments.Scientific theory is governed by hypothesis or assumptions that scientists are responsible for verifying.

It should be noted that there are two kinds of ideas that can be developed until a theory is established: the conjectures (assumptions that are not supported by the observations) and the hypothesis (That if they rely on multiple observations) These ideas, experts say, can be false, which is why they do not evolve and do not lead to a theory.

According to the definition that is made scientifically about this word, a theory is formed by the set of concepts, propositions and definitions that are related to each other and that are collected from a systematic point of view of phenomena in order to explain or be able to predict a certain phenomenon.

A question that usually arises in the face of this concept is what is the theory for ? it serves to explain reality (because, as, when the phenomenon under study occurs), to order it in a series of concepts and ideas; It is the definitive end of any scientific research.

First the theory must be presented , then explain why it is necessary to analyze the phenomenon and finally Explain your ideas clearly and concisely.You can analyze a complex phenomenon that keeps in its essence other specific phenomena, for example: the theory of relativity can be explained in broad strokes or do it descriptively in each of the phenomena that form it.It should be noted that it is common that to explain or predict any phenomenon of reality it is necessary to carefully analyze several theories that are intercepted, in order to find the different characteristics of the phenomenon and review each of its aspects properly.

The term can also refer to the ideas that someone has about a certain thing, or to the set of knowledge or reasoning that have been made on an issue, which have not been taken to empirical procedures to prove its truthfulness .It is also wrong to speak of theory when referring to the concepts that some author has on a certain subject, however in this case theory is confused with data pertaining to the study of the history of the ideas.

On the other hand, it is worth mentioning that a theory is different from a theorem.While the theory consists of a pattern of physical events that cannot be proven using basic axioms, the theorem is a proposition of a mathematical event that follows a group of axioms under a logical criterion .
