Meaning of Theory

What is Theory:

Theory is a term that comes from the Greek youhistory which in the historical context meant look, contemplate either to study And he meant more of a speculative thinking.

In its evolution, the term came to designate the core set of ideas of a given topic, which seeks to convey a general vision of some aspects of reality. This made up of a set of hypotheses.

There are two categories of ideas that can lead to theories:

  • conjecture: if a guess is not supported by observations,
  • hypothesis: supported by testable observations. Despite this, a hypothesis can turn out to be false. When this occurs, the hypothesis must be modified to fit the observation, or discarded.

  • Hypothesis.

In science, a set of descriptions of knowledge is called called a theory only when it has a firm empirical basis.

A Scientific theory it is the speculative part of a science, as opposed to the practical. It is a consistent system made up of observations, ideas and axioms or postulates, and all of this constitutes a set that tries to explain certain phenomena. Examples of scientific theories are:

  • Chaos theory,
  • Communication theory
  • theory of knowledge
  • evolution theory
  • game theory
  • Theory of relativity
  • quantum physics theory

Theories exist not only in the natural sciences and exact sciences, but in all fields of academic study, from philosophy to literature to social science.

In many circumstances, theory is seen as a model of reality. A theory has to be somehow testable. Many scientists argue that religious beliefs are not verifiable and, therefore, are not theories but matters of faith.

Popularly, theory is a word that is used to refer to a set of abstract ideas to explain some event, it even allows predictions of that event. It is also used to describe something difficult to achieve in practice, for example “his ideas of him to improve the situation of the country are pure theory”.

The ‘theoretical term’ or ‘in theory’ is used to indicate the difference between the data obtained from the model with respect to the observable phenomena in the experience or experiment of reality. It often indicates that a particular result has been predicted by theory but has not yet been observed.
