Tip 1: Why you need physics

Physics Is one of the most important sciences. It has had such a serious impact on the life of mankind that it's just impossible not to notice. Nevertheless, many people do not immediately answer the question of its purpose.

It is difficult to overestimate the merits of physics. Being a science that studies the most common and fundamental laws of the world around us, it has unrecognizably changed the life of a person. Once the terms "physics" and "philosophy" were synonymous, since both disciplines were aimed at understanding the universe and governing laws. But later, with the onset of the scientific and technological revolution, physics became a separate scientific direction. So what did she give to humanity? To answer this question, it is enough to look around. Thanks to the discovery and study of electricity people use artificial lighting, their lives are facilitated by countless electrical devices. The study by physicists of electric discharges led to the discovery of radio communications. It is thanks to physical research around the world that they use the Internet and cell phones. Once scientists were confident that the apparatus heavier than air could not fly, it seemed natural and obvious. But the Montgolfier brothers, the inventors of the balloon, and behind them the Wright brothers who created the first plane, proved the groundlessness of these statements. It is thanks to physics that mankind has put into its service the power of steam. The appearance of steam engines, and along with them steam locomotives and steamers, gave a powerful impetus to the industrial revolution. Due to the strength of the pair tamed the people were able to use in factories mechanisms not only to facilitate the work, but also in the tens and hundreds of times raising his proizvoditelnost.Bez this science would not be possible, and space travel. Thanks to Isaac Newton's discovery of the law of universal gravitation, it became possible to calculate the force necessary to bring a spacecraft into Earth's orbit. Knowledge of the laws of celestial mechanics allows launched from Earth space probe successfully reach other planets, breaking millions of kilometers and precise output to the assigned tseli.Mozhno no exaggeration to say that the knowledge obtained by the physicists of the century, the development of science, are present in every field of human activity. Take a look at what is now around you - in the production of all the objects around you the most important role was played by the achievements of physics. In our time, this science is actively developing, it has a truly mysterious direction, like quantum physics. The discoveries made in this field can unknowingly change a person's life.

Tip 2: Why you need philosophy

In the era of industrial and technologicalProgress philosophy has receded into the background, not everyone can clearly answer the question of what kind of science and what it does. People are busy with pressing problems, they are little interested in divorced from life philosophical categories. Does this mean that philosophy has lost its relevance and is no longer needed?

Philosophy is defined as a science that studiesThe root cause and the beginning of everything. In this sense, it is one of the most important sciences for man, as it tries to find an answer to the question of the cause of human existence. Why does man live, why is this life given to him? The answer to this question determines the ways that a person chooses. Being a truly comprehensive science, philosophy includes a variety of disciplines and tries to find answers to important questions for human existence - is there any God, what is good and evil, the questions of old age and death, The possibility of an objective knowledge of reality, etc. etc. It can be said that the natural sciences answer the question "how?" While philosophy tries to find an answer to the question "why?" It is believed that the very term "philosophy" is coined by Pythagoras, in Greek it means "love of wisdom ". It should be noted that unlike other sciences, in philosophy no one is obliged to base their arguments on the experience of predecessors. Freedom, including freedom of thought, is one of the key concepts for the philosopher. Philosophy arose independently in Ancient China, Ancient India and Ancient Greece, from where it began to spread throughout the world. Classification of existing philosophical disciplines and directions is quite complex and not always unambiguous. In general philosophical disciplines includes metaphilosophy, or the philosophy of philosophy. There are philosophical disciplines that explore ways of knowing: logic, the theory of knowledge, the philosophy of science. Theoretical philosophy includes ontology, metaphysics, philosophical anthropology, philosophy of nature, natural theology, philosophy of spirit, philosophy of consciousness, social philosophy, philosophy of history, philosophy of language. Practical philosophy, sometimes called the philosophy of life (axiology), includes ethics, aesthetics, praxeology (philosophy of activity), social philosophy, geofilosophy, philosophy of religion, law, education, history, politics, economy, technology, ecology. There are other directions of philosophy, you can get acquainted with the full list by looking into specialized philosophical literature. Despite the fact that the new century seems to leave little room for philosophy, its practical significance does not diminish at all - humanity is still looking for answers to questions of concern to it being. And the answer to these questions depends on which way human civilization will go in its development.

Tip 3: Why Labor Discipline

Discipline in the broadest sense - followingestablished rules, regulations. In production, these regulations and regime restrictions are determined by an officially approved document - "Internal Regulations". With them, the employee gets acquainted when hiring, and signing a labor contract, he formally undertakes to fulfill them.

Ideally, in an enterprise where it is installed"Iron" discipline, all employees strictly and accurately observe the order, mode of operation and rules established by laws, by-laws and local acts, regulations, instructions and orders for the organization, and also strictly follow the orders of managers. It is clear that such a discipline can not be found even in the army. But how much is it necessary and what is it for? Discipline is designed to ensure unity and continuity in the working and technological processes, which affects the quality of the products and services provided. It is the discipline that makes the production behavior of employees predictable, amenable to planning and forecasting. This allows to ensure the interaction of those only at the level of ordinary performers, but also between the units of the enterprise as a whole. It affects the efficiency of labor, and, therefore, its quantitative and qualitative indicators. There are objective and subjective aspects of discipline. Objective finds expression in the system of established norms and rules that operates in the enterprise. Subjective represent the desire of each employee to fulfill them. The task of the management is to create such conditions in the company when the requirements of the discipline would be higher than the interests of individual members of the work collective. In this case, there is no need to exercise control and restraining functions on the part of the leadership - the team itself is mobilized to combat mismanagement, bureaucracy, absenteeism and other phenomena that interfere with normal work. Do not expect the employees to meet discipline standards, when the company's management itself constantly violates it , unreasonably involving them to unscheduled and emergency work, work during after-hours and days off. In this case, the staff fairly rightly believe that labor discipline in a normal working day can be violated, because they work out-of-hours. If you are a manager, then start fulfilling the requirements of discipline with yourself. Only in this case you can demand this from your subordinates and avoid sabotage.

Tip 4: What are the synonyms for?

It would seem that the fewer words in the language, the easier it is to communicate. Why "think out" such different words to mean the same, in fact, an object or phenomenon, i.e. Synonyms? But with careful consideration of them it becomes clear that the synonyms carry a number of absolutely necessary functions.

Wealth of speech

In the writings of junior schoolchildren, it is often possibleto find a text about this: "The forest was very beautiful. There grew beautiful flowers and trees. It was such a beauty! ". It happens because the vocabulary of the child is still quite small, and he has not learned to use synonyms. In the speech of an adult person, especially written ones, such repetitions are considered a lexical mistake. Synonyms allow you to diversify speech, enrich it.

Shades of meaning

Each of the synonyms, although it expresses a similarmeaning, but gives it its own special connotation of meaning. So, in the synonymic series "unique - amazing - impressive" the word "amazing" means an object that causes surprise in the first place, "unique" - an object that is not similar to the rest, unique in its kind, and "impressive" - producing a strong impression, but this impression can be something different than a simple surprise, and also this object can be similar to those similar to it, i.e. not to be "unique".

Emotional-expressive coloring of speech

The synonymic series contains words havingDifferent expressive and emotional significance. So, "eyes" - the word neutral, denoting the organ of vision of a person; "Eyes" - a word belonging to the book style, also means the eyes, but, as a rule, large and beautiful. But the word "burqaly" also means big eyes, but not distinguished by beauty, rather ugly. This word carries a negative evaluation and belongs to the conversational style. Another colloquial word "zenki" also means ugly eyes, but small in size.

Refinement of the value

Most borrowed words havea synonym for analogy in the Russian language. They can be used to clarify the meaning of terms and other special words of foreign origin, which may be incomprehensible to a wide range of readers: "Preventive measures will be taken. preventive measures "

Comparison of similar values

Paradoxically, synonyms can expressand opposite shades of meaning. Thus, in Pushkin's Eugene Onegin, the phrase "Tatiana looks and does not see" occurs, and this is not perceived as a contradiction, because "looking" is "looking at a certain direction," and "seeing" is "perceiving and to comprehend what is before our eyes. " Similarly, the phrase "equal, but not identical," "not just thinking, but reflecting," etc., does not cause rejection.

Tip 5: Physics as a fundamental science

Physics is a science that studies the fundamental laws of the material world, describing, through laws, the properties and motion of matter, the phenomena of nature and its structure.

Instructions

Fundamental science (in the general sense) isscience describing the surrounding world with the help of theoretical and experimental research of scientific phenomena. Since ancient times, scientists have been interested in the occurrence of such natural phenomena as thunder, lightning, etc. This gave rise to physics, as a science that requires scientific evidence and experiments. Physics is based on facts that require experimental evidence and are written mathematically. Nowadays physics is divided into 3 sections: macroscopic physics, microscopic physics and physics, combined with other sciences.

Macroscopic physics includes: mechanics, which studies the mechanical motion of material bodies and the interaction that takes place in this process; thermodynamics, studying the properties of macroscopic systems in a state of thermal equilibrium; optics, which studies the laws of light and electromagnetic waves; electrodynamics, explaining the nature and properties of electromagnetic fields.

Microscopic physics includes atomic,Statistical, quantum, nuclear physics, as well as the physics of condensed matter and elementary particles. Atomic physics studies atoms, their structure, properties, processes occurring at the atomic level. Statistical physics is devoted to the study of systems with an infinite number of degrees of freedom.

The beginning of quantum physics was given by quantum lawsMechanics and quantum field theory, which allow us to study the properties of quantum-mechanical and quantum-field systems. Nuclear physics is a science that studies nuclear reactions, the structure and properties of atomic nuclei. Condensed matter physics studies the behavior of systems with large degrees of freedom and strong coupling. The physics of elementary particles, or subnuclear physics, is devoted to elementary particles, their properties and interactions.

Physics can also come into close contact with otherssciences, such as geology, mathematics, biology, chemistry, etc. There also appeared astrophysics, developed at the junction of astronomy and physics, studying the physical phenomena of astronomical objects; Computational physics, mathematically solving the problems of physics; biophysics, devoted to physical processes in biological systems; geophysics, which studies the structure of the Earth by physical methods and many other branches.

All these sections constitute physics, making ita fundamental science of nature and phenomena, without which in our time can not do. On the laws of physics, our whole world is built, technology and electronics are being developed, cities are being built.
