Among the many scientific disciplines, physics is one of the most interesting. Thanks to it, many processes are comprehended, technologies are improved and discoveries are made. In the article, we will consider what the science of physics is and its applied part.
Description of science
In order for all invented machines and technological solutions to be successfully put into operation, scientists have to solve many related problems. Applied physics helps them in this. It includes a body of knowledge, the purpose of which is to find solutions to specific technological and practical problems.
The main goals and objectives of applied science include:
- The study of the general laws of the existence of nature, as well as the structure and physical properties of matter.
- Formation of the laws of natural science.
- Using math as the basis for doing calculations.
- Performing experiments to prove theoretical results.
Methods of Applied Science
Applied physics is also called experimental. It helps to discovermistakes in theory by setting up experiments.
Research is carried out by the following methods:
- Controlled experiments. These are experiences that are subject to human correction in the process. For example, laboratory research. Under such conditions, almost any situations and their outcomes can be simulated, theoretical knowledge can be corrected, and the experiment can be repeated.
- Natural experiments. These are those that are carried out in the normal habitat or existence of the test object. The minimum influence of the human factor or its complete absence is important here. Such experiments are carried out, for example, in astrophysics when observing the movements of astronomical objects.
Experimental physics is divided into the following types:
- radiation and biophysics;
- ecology;
- experimental nuclear science;
- particle physics;
- plasma physics;
- nanosystems;
- solid state physics and other industries.
How different from theoretical science
Applied physics aims to consider a phenomenon not for the purpose of studying it, but in the context of solving technical problems. It differs from "pure" science, which is based on basic aspects, in that the experiment is carried out on the basis of the theoretical knowledge gained.
Applied physics does not solve the problems of fundamental research. It offers options for the effective use of technology in practice.
Physics is a science that is connectedwith all disciplines. Her research is applicable in many areas. For example, nuclear technology, mobility, electronics and electrical engineering, medicine, nanoscience, measurements and building structures, and much more.
As a rule, a group of scientists deals with the practical aspect of physics. They can work privately and under the state program. Many institutes and faculties conduct their own research and share the results with the world.
Journal of Physics
In Russia, the journal "Applied Physics" is a popular publication. It contains a summary of the latest research and developments that can be put into practice in the future.
The magazine has its own website and editorial board. It has been produced since 1994 and managed to win the trust of the scientific community. It publishes articles on various topics: discussions at conferences, applied aspects of technologies in the laser, ion beam, plasma, photoelectronic, microwave fields and many other areas.
A separate publication is issued, which describes extensive research programs and analytical reviews - "Advances in Applied Physics". Here you can find similar topics, but with more detailed information.
Modern projects
In the modern scientific community, some kind of experiment in physics is being carried out all the time. At the moment, the important ones are:
- Heavy Ion Collider - LHC. This is the particle accelerator that waslaunched in 2008. The purpose of his work is to study the interaction (impact against each other) of charged particles - protons and heavy ions. The study is being conducted on the territory of Geneva. It is the largest such experimental facility to date.
- Space telescope named after James Webble. This device is expected to replace the Hubble in the spring of 2019 and will carry out observations until 2023. The technology involves research in the field of astrophysics, exoplanetology and the study of the water worlds of the solar system. The project is based on the interaction of 17 countries of the world and is headed by NASA. A significant contribution to the development was made by the European and Canadian space agencies.
It can be said that no research can do without applied physics. Theoretical knowledge is necessarily subject to changes in practical tests. It is applied science that helps to put them into practice.
