Many wonder: "What is studying physics?".Let's try to explain.The word is of Greek origin and translates it as nature.It was first recorded in the writings of the greatest thinkers of Aristotle, who lived BC in the IV century.This is one of the oldest sciences, natural sciences area, while in Russia it appeared thanks to MVLomonosov.He published the first textbook on the subject.
carefully looked closer to what is happening around us, we see all the diverse phenomena and changes that take place all over the place, all that studying physics.They come from substances and bodies in the world, and are called phenomena.For example: the water in the kettle, standing on the fire begins to boil, a piece of ice melts into the room, passed through the wire an electric current, it heats hot, lightning, thunder, wind.The phenomena are magnetic, mechanical, acoustic, thermal, electrical and lighting.The most fundamental and general laws that determine the evolution and structure of the material world - that's all that studying physics.
physical phenomenon called all the processes of transformation of matter or manifestation of their properties, taking place without changing the composition of the substance.This science has the unusual feature.The uniqueness lies in the fact that studies the physics of simple phenomena, but they can be used to deduce the general laws.Its mission is to explore and discover the laws relating the phenomena that occur in nature.They are the basis of all natural science.
Examples are myriad.One of them - a fall of different bodies on the ground caused by the Earth's gravity.The change of the day and night due to its rotation around its axis.Many sciences, such as astronomy, biology, geography, chemistry - all of them are studying the nature and always apply the laws of physics.All that studying this branch of knowledge is vital to human existence, development of society, knowledge of the world and much more.Its importance in today's world is extremely large.
all the difference in today's world of the past centuries have occurred as a result of physical discoveries in practice.Basic physics - it's an experiment.All laws were derived empirically.They represent the quantitative relationships expressed in mathematical language.In general, physics is divided into parts:
- experimental.Its goal is to establish new facts and test hypotheses and well-known physical laws;
- theoretical.Focusing on the fundamentals of physics and its laws, explains the natural phenomena and predict new ones.
structure of science is very complex.It includes a variety of topics and subjects.Depending on what processes are studied and what stands out form of motion, push the mechanics of solids and material points continua (speakers included), and the static, thermal and electrodynamics, optics, quantum mechanics, field theory and gravitation.
very interesting section - the quantum.For many in the hearing, but not everyone knows that studying quantum physics.This study and the study of the microcosm.Its objectives - description of the interaction of matter and energy in the elementary particles.Plain language of such a complicated science is almost impossible to tell.One of its concept of the quantum, which is an elementary indivisible particles of matter or energy.
In many ways that is studying quantum physics, there are a number of paradoxes, inexplicable things over which fought and continue to fight the best minds of the planet.For example, here are several terms that are related Unexplained phenomena.For example, volnochastitsa - electron can behave like a wave, or the Heisenberg uncertainty principle - they defy the laws of Newton.
