What are the sections of physics

Introduction

You went to the seventh grade and, having come to school on September 1, saw in the list of their new lessons an object with the name "Physics". On your question about what kind of animal it is, parents just waved: "Science is like that!" But before the first lesson in physics, you want to prepare thoroughly, so that during its study you should not be surprised at anything. As everyone knows, science is divided into different sections, and the one described in this article is not an exception. What sections of physics exist and what do they study? This is how the question in this article sounds.

Main Sections of Physics

This item is divided into three large sections, which, in turn, are divided into subsections. And the latter also differentiate into the types of these subsections. So, there are only three sections of physics that can be called basic: macroscopic, microscopic and physics at the intersection of sciences. Let's look at them in order.

1. Macroscopic physics

• Mechanics. He studies the movement and interaction of material bodies. It is divided into classical, relativistic and mechanics of continuous media (hydrodynamics, acoustics, solid-state mechanics).
• Thermodynamics. He studies the transformations and relationships of heat and other forms of energy.
• Optics. He considers the phenomena that are associated with the propagation of electromagnetic waves (infrared and ultraviolet radiation), i.e. Describes the properties of light and light processes. It is divided into physical, molecular, nonlinear and crystal-optics.
• Electrodynamics. He studies the electromagnetic field and its interaction with bodies that have an electric charge. This section is divided into electrodynamics of continuous media, magnetohydrodynamics and electrohydrodynamics.

2. Microscopic physics

• Atomic physics. He is studying the structure and states of atoms.
• Static physics. He studies systems with an arbitrary number of degrees of freedom. It is divided into static mechanics, static field theory and physical kinetics.
• Condensed matter physics. He studies the behavior of complex systems with strong coupling. It is distributed to the physics of solids, liquids, nanostructures, atoms and molecules.
• The quantum physics. He studies quantum-field and quantum-mechanical systems and the laws of their motion. It is subdivided into quantum mechanics, field theory, electrodynamics and chromodynamics, as well as string theory.
• Nuclear physics. He is studying the properties and structure of atomic nuclei and nuclear reactions.
• High energy physics. He considers the interaction of the nuclei of atoms and / or elementary particles, when their collision energy is greater than their mass.
• Physics of elementary particles. He studies the properties, structures and interactions of elementary particles.

3. Physics at the intersection of science

• Agrophysics. He is engaged in studying the physicochemical and biophysical processes occurring in the soil.
• Acoustooptics. He studies the interaction of acoustic and optical waves.
• Astrophysics. Engaged in the study of physical phenomena occurring in astronomical objects.
• Biophysics. He studies the physical processes that take place in biological systems.
• Computational physics. He studies numerical algorithms for solving problems in physics, for which a quantitative theory has already been developed.
• Hydrophysics. He is engaged in studying the processes occurring in water, and its physical properties.
• Geophysics. Explores the structure of the Earth by physical methods.
• Mathematical physics. The theory of mathematical models of physical phenomena.
• Radiophysics. He studies vibrational-wave processes of various nature.
• The theory of oscillations. Considering all possible fluctuations, proceeding from their physical nature.
• Theory of dynamical systems. Mathematical abstraction, designed to study and describe the evolution of systems in time.
• Chemical physics. Science of the physical laws governing the transformation and structure of chemicals.
• Physics of the atmosphere. He is studying the structure, composition, dynamics, and phenomena in the atmosphere of the Earth and other planets.
• Plasma physics. He studies the properties and behavior of plasma.
• Physical chemistry. He is engaged in the study of chemical phenomena with the help of theoretical and experimental methods of physics.

Conclusion

These are all sections of physics. With some of them (for example, optics) you will get acquainted in detail in the school, and some will study at the institute if you enter the faculty with the same name. And in-depth study of the physics section you can at home at any convenient time.
