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 consider what science is physics and its applied part.
Description of Science
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 set of knowledge, the purpose of which is to find solutions for 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.
- The formation of the laws of science.
- Using mathematics as the basis for calculations.
- Conducting experiments to prove theoretical results.
Applied Science Methods
Applied physics is also called experimental. It helps to detect errors in theory by setting up experiments.
Research is carried out by the following methods:
- Guided experiments. These are experiments that are subject to human correction in the process. For example, laboratory studies. In such conditions, almost any situations and their outcomes can be modeled, theoretical knowledge corrected, and a repetition of experience possible.
- Natural experiments. These are those that are conducted in the normal habitat or existence of the test object. The minimal 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.
What is different from theoretical science
Applied physics sets its task to consider the phenomenon not with the aim 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 conducted on the basis of theoretical knowledge.
Applied physics does not solve the problem of basic research. It offers options for the effective use of technology in practice.
Physics is a science that is connected with all disciplines. Her research is applicable in many areas. For example, nuclear technology, mobility, electronics and electrical engineering, medicine, nano research, measuring and building structures, and much more.
As a rule, a group of scientists is involved in 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 result with the whole world.
Physics Journal
A popular publication in Russia is the journal Applied Physics. Here you can find brief information on the latest research and achievements that can be put into practice in the future.
The magazine has its own website and an editorial board. Issued since 1994 and managed to gain 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 edition is published, which describes the extensive research programs and analytical reviews - “Successes in Applied Physics”. Here you can find similar topics, but with more detailed information.
Modern projects
In the modern scientific community, all kinds of experiments in physics are conducted. Currently important are:
- Heavy Ion Collider - LHC. This is a particle accelerator that was launched in 2008. The aim of his work is to study the interaction (stress on each other) of charged particles - protons and heavy ions. The study is conducted in Geneva. Today it is the largest such experimental facility.
- Space telescope named after James Webble. This device is supposed to replace the Hubble in the spring of 2019 and will conduct observations until 2023. The technology involves research in astrophysics, exoplanetology and the study of the water worlds of the solar system. The project is based on the interaction of 17 countries and is led by NASA. A significant contribution to the development was made by the European and Canadian space agencies.
We can say that not a single study can do without applied physics. Theoretical knowledge is necessarily subject to change in practical tests. It is applied science that helps to put them into practice.
