Physics is a science with clear experimental value by means of which theories and laws are extracted. This discipline is divided into three fundamental branches: classical, modern and contemporary.
What is the object of study of classical perspective? The analysis of those phenomena whose speed is infinitely less than the speed of light. From the historical point of view, this branch of physics includes those investigations carried out before the 20th century. This branch of knowledge also integrates scientific phenomena of magnitude.
In contrast to modern physics that takes the analysis of particles as its object of study, which values the analysis of microscopic reality.
Classical physics also shows a model of the world governed by mechanistic laws in the worldview of the physical universe. From this perspective, the universe could be explained metaphorically as the gear of a perfect clock whose elements move by means of a law of causality.
Parts of classical physics
This concept is made up of different specific branches:
1. Thermodynamics: study the relationship between heat and energy as elements that transform bodies. Furthermore, energy can also become a working formula, that is, a principle of movement.
2. Mechanics: analysis of entities in motion and at rest, as well as their development over time. In this context, the laws relating to motion proposed by the scientist Isaac Newton are also integrated.
3. Optics: light analysis.
4. Sound: study of how sound propagates and how waves move through matter.
5. Electricity and magnetism: analysis of electricity both in motion and at rest. This is called electromagnetism.
This section of physical science shows a clear contrast with quantum physics that emerges as a solution to give answers to phenomena for which the explanations had until then were not definitive.
Modern physics
This quantum physics integrates mathematics, on the contrary, the classical formula gives greater value to metaphysics. Modern physics carried out since the 20th century integrates the study of cosmology, particle physics, molecular and quantum physics. That is to say, a new paradigm emerges with respect to the classical theories about the universe.
