Branches of physics

Blackboard

Physics is the science of matter and its motion. The term physics comes from the Greek 'fusis', meaning "nature", and the 'fusike' means "knowledge of nature." In a nutshell, physics is a science whose purpose is to try to understand the world around us.

The main branches of physics

With the maturity of physics, the physical phenomena observed in nature have been subdivided into several special branches. Although all fields of physics are simultaneously considered as a single theory, this idea has not yet been proven. The basic branches of physics are:

1. Conventional mechanics: In metallurgical mechanics, the material-scientific model of the action of the force on objects is discussed. This model is decisive (deterministic). Traditional mechanics is considered to be the limit of quantum mechanics, though it is not yet possible to prove it. Traditional mechanics can be further divided into two parts:
1. Newtonian Traditional mechanics, named after Isaac Newton and his laws of motion.
2. Relativistic mechanics, according to Albert Einstein and his general relativity theory and special relativity theory.
2. Quantum mechanics: This branch discusses nuclear and ultra-nuclear systems and their relation to radiation, subject to observable amounts. The basis of quantum mechanics is the observation that all kinds of energy are released in the form of a bunch of discrete units, which are called quanta (plural). In quantum theory, only probabilistic or statistical calculations of the different properties of observable particles are possible, and they are discussed in the form of wave functions.
3. Electromagnetism: The physics of the electromagnetic field is discussed in this branch. The electromagnetic field is a field that is pervading everywhere and can apply force to electrically charged particles. Similarly, the presence and conduction of electric charges can adversely affect an electromagnetic field.
4. Statistical mechanics and thermodynamics: These disciplines discuss heat, work and entropy. The power of macroscopic systems is discussed in thermodynamics, and the effects of temperature, pressure, volume, mechanical work, etc. are studied. In statistical mechanics, the application of statistics to the microscopic elements of macroscopic systems combines the macroscopic view of thermodynamics and the atomic behavior of materials defined in either quantum or quantum mechanics.
