Introduction
you moved into seventh grade and came on September 1 in a school and saw the list of its new object lesson titled "Physics".On your question about what kind of animal, the parents just shrugged: "Science that!"But before the first lesson you want to thoroughly prepare physicists to study during her nothing surprising.As is known to all sorts of science are divided into sections, and described in this article is no exception.What are the areas of physics, there are and what they are learning?So it sounds considered in this article the issue.
main sections of physics
This course is divided into three large sections, which, in turn, are divided into subsections.And the latter also to differentiate types of subsections.Thus, sections of physics, which can be called the main, only three: macroscopic, microscopic and physics at the intersection of science.Let's take them in order.
1. The macroscopic physics
- Mechanics.Study the movement and interaction of material bodies.Divided into classical, relativistic and continuum mechanics (hydrodynamics, acoustics, mechanics of solid).
- Thermodynamics.Learning conversion ratio and heat, and other forms of energy.
- Optics.Examines effects that are associated with the propagation of electromagnetic waves (infrared and ultraviolet radiation), ie,It describes the properties of light and light processes.Divided into physical, molecular, and non-linear crystal optics.
- Electrodynamics.Learning the electromagnetic field and its interaction with the bodies that have an electric charge.This section is allocated to the electrodynamics of continuous media, and magneto-hydrodynamics electrohydrodynamics.
2. Microscopic physics
- Atomic Physics.Deals with the study of the structure and states of atoms.
- statistical physics.Learning system with an arbitrary number of degrees of freedom.It is divided into static mechanics, static field theory and physical kinetics.
- Condensed Matter Physics.Studied the behavior of complex systems with strong coupling.Distributed in the physics of solids, liquids, nanostructures, atoms, and molecules.
- Quantum Physics.Learning the quantum field and the quantum-mechanical systems and laws of their movement.Divided into quantum mechanics, field theory of electrodynamics and chromodynamics and string theory.
- Nuclear Physics.He has been studying the properties and structure of atomic nuclei and nuclear reactions.
- High Energy Physics.The interaction of the nuclei of atoms and / or elementary particles, when their collision energy greater than their weight.
- Elementary Particle Physics.It studies the properties, structure and interactions of elementary particles.
3. Physics at the intersection of science
- Agrophysics.He engaged in the study of the physico-chemical and biophysical processes occurring in the soil.
- acoustooptics.Studies the interaction of acoustic and optical waves.
- Astrophysics.He engaged in the study of physical phenomena occurring in the astronomical objects.
- Biophysics.Learning the physical processes that occur in biological systems.
- Computational Physics.Learning numerical algorithms for solving problems in physics, which has developed a quantitative theory.
- Hydrophysics.It deals with the study of the processes occurring in the water, and its physical properties.
- Geophysics.We study the structure of the Earth by natural means.
- Mathematical Physics.The theory of mathematical models of physical phenomena.
- Radio.Learning vibration-wave processes of different nature.
- Theory of oscillations.Consider all possible fluctuations in terms of their physical nature.
- theory of dynamical systems.Mathematical abstraction designed to study and describe the evolution of systems in time.
- Chemical Physics.The science of physical laws that govern the structure and the transformation of chemicals.
- Atmospheric Physics.It engaged in the study of the structure, composition, dynamics and phenomena in the atmosphere of the Earth and other planets.
- Plasma Physics.To study the properties and behavior of the plasma.
- Physical Chemistry.Investigates chemical phenomena using theoretical and experimental methods of physics.
conclusion
It all branches of physics.With some of them (eg, optical), you will learn in detail in the school and some will study at the institute when he entered the faculty of the same name.A study in depth the topics of physics, you can at home at any time.
