Physics and its motion science. The English term "Physics" comes from the Greek φύσις (Phunis) meaning "nature", and φυσικῆ (blown), that is, "knowledge about nature". To say very abstractly, physics is the science that aims to understand the world around us.
Physics (Ancient Greek: φυσική (ἐπιστήμη). Physikḗ (epistḗmē), φύσις physis "Nature" is a matter of "knowledge of nature" and its speed through space and time Behavior, along with the concept as such as strength and force. One of the most fundamental scientific branches, the main goal of physics is to understand how the universe can be treated.
Physics is one of the oldest academic subjects, perhaps the oldest by the incorporation of astronomy. In the last two millennia, physics was part of natural philosophy, along with some branches of chemistry, biology and mathematics, but during the 17th century scientific revolution, natural sciences turned into a unique research program as their own right. .Physics research Many of inter-areas, such as intersections jaibabijnana and quantum chemistry, and physics is not defined strictly limits new ideas in physics often explain the basic methods of science The case study mathematics and philosophy, while opening new ways.

Physics also makes significant contributions through the advancement of new technologies arising from theoretical successes. For example, advances in the development of electromagnetism or nuclear physics have directly led to the development of new products, which dramatically transformed into a modern society such as television, computer, home appliances and nuclear weapons;The development of thermality has led to the development of industrialization, and the development of calculus development in mechanics Inspired Recall. See the glossary of physics:

Physics is one of the oldest branches of knowledge and its modern ancestral name is Astronomy. Research in nature is one of the primitive work of human beings, but physics is what is meant today, in the scientific revolution of the 16th century, when it becomes a science following scientific method Before that the common name of the research on nature was Pv Rtika philosophy, which is not exactly science.

The person involved in the study of physics as an enlightening knowledge or scripture of the subject matter is known as a physicist. Physicists try to understand the way the physics around us behaves, and why they behave or do those behaviors. They proposed the hypothesis for this purpose, and they are closely related to observational data. From this point of view, physics relates to chemistry and biology. The Scriptures also relate to philosophy and mathematics. The relation and reliance of all the scriptures mentioned above is not defined, but rather complex. In order to better analyze the nature, scientific research on this has been divided into three major sciences in physics, chemistry and biology. Basic and composite materials are discussed in chemistry, life and living things are discussed in biology, and the rest is discussed in physics. Physics relationship with philosophy and mathematics is more complex. Until the birth of modern science, the content of physics would have been discussed in philosophy, and the subjects discussed in various branches of current philosophy are intended by physicists to explain in the future (i.e., the metaphysical concepts like existence), although it may not be possible. The theories and theories of physics are universally published with the help of mathematical equations. Mathematics is often referred to as the language of physics. It may seem apparently that with the mathematics of all the above, the relationship between physics is the most intensive. Physics has directly supported the development of some of the mathematical disciplines, such as vector analysis. There are many such people in science history who were both proficient in mathematics and physics, such as Newton, Euler, Gauss, Poincaré. Physics and mathematics divide the physical sciences into the two primary branches of theoretical physics and experimental physics.

Theoretical physics and its associated scripture are generally proposed in mathematical physics, and these electrons are tested in nature in experimental physics. These two branches complement each other: theories are examined, and in the end, advanced theories are proposed, which are examined again and so on. Physics research is mainly done in educational institutes or professional laboratories, and it is not known in private enterprise in the modern era. Theoretical activities are largely personal, but it is based on discussions and collaboration with other physicists. In the modern age, physicists have generally mastered the special field of physics, which is in contrast to the past works of physicists.On the other hand, Newton, Euler or Gauss have contributed substantially to each of the different departments of physics, it is hard to find such a modern physicist.

Physics is an important knowledge branch from the technical perspective. Physicists work in various fields, such as electricity, motor transport, medical (especially X-ray usage), etc. However, many times physics has been used as an atomic bomb for nuclear bombs.

Although the physicists have been trying to understand the nature for the last 400 years, there are still many problems in nature which have not been found even today. As a result physics is still an active scripture; Thousands of researchers around the world are involved in the study of physics. Compared to any time in the past, the amount of research and the range of physics is two more. Modern theories of physics did not just give deeper descriptions of nature, its unique and mysterious form made us more clear.

History of Physics

Since ancient times, there was curiosity on many aspects of human nature. All of these curiosity has originated from science, and it has been started by physics. Physics is not only about material or numerical causes, but also in the development of technological development, there is an outstanding role in physics.
