We explain what physics is and the four basic domains in which it is divided. In addition, their interests and different branches of study.
Physics, from the Greek physis (“nature”), is the natural science that deals with the study of four fundamental concepts of reality , in which the laws that govern the universe seem to stand: energy , matter , time and the space, as well as the interactions between them.
Physics is one of the oldest academic disciplines , whose roots date back to the beginning of civilization, when man began trying to understand the forces that govern the world around him.
It is a discipline both theoretical (description of the laws of the universe) and experimental (implementation of hypotheses regarding these laws), and adheres to the model of verification and legitimation driven by the scientific method . It is one of the fundamental or central sciences, within whose field of study chemistry, biology and electronics often converge , among others.
Initially physics was part, like so many other sciences, of the natural philosophy or philosophy of antiquity, but from the Scientific Revolution of the 17th century it emerged as an independent field, interested in the fundamental laws of reality and using formal language of mathematics to express them. At present, however, physics is one of the disciplines that most contributes to the change of the scientific, industrial and technological paradigm .
Physics as we know it today is divided into four basic domains, that is, four approaches to the phenomena of nature, based on two fundamental considerations: the size of matter and the speed of its movement. These four domains are:
Physics deals with the fundamental laws of the universe , that is, to understand and describe the mechanics with which reality operates. This goes through the four fundamental interactions known:
Physics comprises a set of subdisciplines that are:
Chemistry is a discipline that presents points of contact with physics , particularly in its interest in the subject: chemistry studies the methods of its composition and the reactions that can occur to other chemical substances or to the presence of heat and The other forms of energy.
Therefore, chemistry has a more focused perspective than physics, and it does not come from natural philosophy, but from medieval alchemy that sought among other things to convert common elements into precious metals.
