Opening in the Physicist |
| the Role of history of a science is connected first of all with its consciousness. It is necessary for scientists, that it is better to understand occurring changes to estimate a place of any direction in the most complicated developing system of knowledge. A.Shamin OPENING IN THE PHYSICIST Physics - a science about the most general properties of a material world; the Greek word physike is meant ' by the nature '. There are two close and at the same time different trades - the experimental and theoretical physics. At them an overall aim - knowledge of the world of things; their methods different, but they are inconceivable the friend without the friend. Physicists-experimenters investigate parities between physical sizes or open nature laws, using experimental installations, making measurements of physical sizes by means of devices. Physicists-theorists study the nature, using only a paper and a pencil, deduce new parities between observable sizes, leaning on found earlier experimentally and theoretically nature laws. The Purpose of experimental and theoretical physics - searches of the general principles underlying laws of the nature, such as causality, laws of preservation, property of symmetry of the world; its purpose is also the reconstruction whenever possible an exact picture of the world, using all known experimental and theoretical facts based on intuition of a guess which will be checked up further on experience. On this nice way of physics of the world gained many brilliant victories though there were also defeats. Supervision, experience and the mathematical analysis were for them means to get into the essence of the phenomena. Here it is told about opening which have played an outstanding role in physics formation as sciences, Indissoluble communication with modern physics find out, on the one hand, astronomy, with another, - technics. The matter is that many outstanding physicists have proved and in astronomies, and physical opening form base for technical inventions. The unity of a macrocosm of stars, galaxies and quasars, and a microcosm of elementary particles becomes conventional. Astrophysics achievements help jadershchikam, and hypotheses of theorists - researchers of thin structure of a matter - prove to be true by means of telescopes and companions. All becomes more appreciable also communication of fundamental science with technics - both direct, and return for new approaches to the physical phenomena frequently are prompted by technics. The Modern physics begins with Galilee and Newton, further the continuous chain of researches has led presently to opening on which the modern nuclear physics and the relativity theory are based. Composers have considered possible to include a number of achievements of modern astrophysics in this section, and also to tell about some little-known prospects of development of technics. It is short informed on the several new experimental facts which yet do not have the explanation. Sections |
