What is Science

Science is knowledge that explains phenomena by obeying laws that have been verified by experimental methods.

Science concept

Aristotle defines science as “knowledge of causes by causes. It is demonstrative knowledge.”

Science is made up of three components: observation, experimentation and the laws. It aims at the union between theoretical knowledge, practice and technique. It does not use assumptions, but the proof after the application of the scientific method.

It was Aristotle himself who defined that the sciences (in the plural) are related to the way of realizing the ideal of scientificity according to the facts investigated and the methods employed.

The criteria for classifying the sciences are:

  • Absence or presence of human action in the fact object of investigation
  • Immutability
  • Practical mobility
  • Science Classification

The sciences are today classified into:

  • Mathematical or logical-mathematical sciences: mathematics, chemistry, biology, astronomy, physical geography, paleontology, physics
  • Human and social sciences: sociology, psychology, human geography, linguistics, archeology, history, economics
  • Applied social sciences: journalism, law, engineering, architecture, library science, informatics

Common sense

The common sense is the union of everyday knowledge. It is subjective, varies from person to person and from group to group.

It is based on the regulatory facts of routine without seeking scientific explanation for them to occur.


Technology is the set of practices and knowledge of a given theoretical field elaborated from a scientific ideal.

It can also be defined as the study and process of methods used for transformation and mastery of the environment.
