Concepts of modern natural science

PREFACE TO THE TWELVE EDITION

Dedicated to young people obsessed with the thirst for knowledge - a source of harmony and perfection


The proposed textbook, along with other books by the author, was awarded a high state award- government awards Russian Federation in the field of education.

More than fifteen years that have passed since the first edition (1997) have shown that this textbook turned out to be useful and interesting for a wide range of readers and, above all, for students of higher educational institutions, including graduates who decided to get a second higher education. This is evidenced by its numerous reprints.

The content of the textbook is interdisciplinary in nature: it covers a wide range of knowledge about nature that everyone needs educated person. Such knowledge is the basic resource for the development of society, the creative power of mankind and an effective means of preserving the natural state of nature.

As a result of studying the concepts of modern natural science, the student should know:

- the main provisions of the knowledge of the world;

– fundamental laws of nature;

– natural science concepts of development;

– natural science foundations modern technologies, energy and ecology;

– ways of solving natural-science problems;

- based on natural science knowledge, to focus their practical activities on the conservation of nature and its richest resources;

- provide all possible assistance in solving natural science problems;

master the skills:

– practical application of knowledge about nature as a basic resource for economic development;

- organization of labor activity with a harmonious combination of nature and man;

be competent:

- in decision practical tasks conservation of the biosphere and saving life on Earth.

Multiple editions of the proposed textbook were revised, supplemented and changed. Compared to the first edition, the latest edition is essentially A new book with didactic elements corresponding to state educational standards. All its chapters include new information and the latest natural scientific achievements.

The textbook is intended for students of higher educational institutions studying in the areas and specialties of management, economics, law, tourism, entrepreneurship, business, ecology, sociology, etc., full-time, evening and correspondence courses.

FROM THE PREFACE TO THE SEVENTH EDITION

With the accumulation of new materials and information, subsequent editions were significantly improved, supplemented, and corrections and clarifications were made to them. When finalizing, it was taken into account years of experience lecturing and holding practical exercises students of various specialties. As a result, the textbook was improved and modified: the number of chapters was reduced from nineteen (in the first edition) to eleven (in later editions), obsolete information was replaced by new ones, some sections were written anew, etc. The seventh edition was revised and corrected.

Precious grains are scattered on the pages of the book, collected over thousands of years by many generations of natural scientists and containing the most necessary, guiding, without which it is impossible to start any creative work.

The concepts of modern natural science are the most important link connecting natural science and humanitarian knowledge and strengthening the fundamental base of all forms of education.

IN modern world rapidly approaching economic, environmental and spiritual and moral crises. The way out of them is quite possible if every person living on our planet awakens the will to natural-scientific and spiritual-moral truth, and if each person makes his own, albeit small, but feasible contribution to solving this complex, global problem. This book will help you find your own way of knowing the truth.

When studying the concepts of modern natural science, it is useful to remember the instruction of the Russian publicist D.I. Pisareva (1840-1868): "You have to study at school, but you still need to study much more after leaving school."

FROM THE PREFACE TO THE FIFTH EDITION

The proposed fifth edition of this textbook has been revised and, in comparison with the previous one, contains new information about the latest major achievements in the field of natural science.

The textbook consists of four parts. Part I substantiates the practical significance of natural science in modern society and the main provisions of the natural-scientific knowledge of the surrounding world are considered. Part II outlines the fundamental laws and concepts of natural science. Part III is devoted to the natural-science concepts of the development of processes in nature. Part IV deals with the natural science foundations of modern technologies, energy and ecology.

The textbook material is presented within the framework of concepts - fundamental ideas and a systematic approach - and is presented in a visual and accessible form.

FROM THE PREFACE TO THE FIRST EDITION

In modern society, much attention is paid not only to various branches of natural science, but also to rapidly developing high technology, energy and ecology. This textbook is devoted to the fundamental concepts of natural science and the natural scientific foundations of modern technologies, energy and ecology.

It consists of five parts, which successively set out the main issues provided for by the state educational standards for studying the discipline "Concepts of modern natural science" in higher educational institutions.

The textbook is written at the level of concepts of natural science problems, i.e., taking into account the fundamental ideas, systems of views on the issues under study. When presenting the material, widely known terms and simple mathematical formulas reflecting the fundamental laws of nature. The natural scientific essence of the issues covered is presented in an accessible form for a wide range of readers.

The book is intended for students of higher educational institutions of daytime, evening and correspondence forms teaching economic, legal, philosophical and other humanitarian specialties.

INTRODUCTION

Finally, I lend a hand to a truly useful science.

Horace


Every person, from a very early age, is distinguished by curiosity - a natural desire to know the world. “Curiosity is akin to a person both enlightened and wild,” said the outstanding Russian historian and writer N.M. Karamzin (1766–1826). With age, unconscious curiosity gradually develops into curiosity - a conscious desire to learn the laws that govern nature, to learn how to apply them in one's work, foreseeing its possible consequences. The laws of nature and the ways in which they are applied reflect the concentrated experience of mankind. Based on it, a person is able to protect himself from mistakes, and it is easier for him to achieve his desired goals. The concentrated experience of humanity underlies any educational process.

Natural science is a unified system of sciences about the laws, phenomena and properties of objects of nature, including many branches - natural sciences.

The most important achievements of natural science form the fundamental basis of modern science-intensive technologies for the production of various products, including consumer goods. In order to know at what price such products are given - the most important component of the economy, what are the prospects for the development of modern technologies that are closely related to economic, social and political problems, we need fundamental knowledge about nature - natural science knowledge. In our time, natural scientific knowledge has become a sphere of active actions and represents the basic resource of the economy, which in its importance surpasses material resources: capital, land, labor, etc. Natural scientific knowledge and modern technologies based on them form a new image life, and a highly educated person cannot distance himself from fundamental knowledge about the world around him without risking becoming helpless in his professional activities. “Without the natural sciences, there is no salvation for modern man; without this healthy food, without this strict education of thought by facts, without this closeness to the life around us, ”the Russian writer and philosopher A.I. gave such a high assessment of natural science knowledge. Herzen (1812–1879).

If we set out in detail the natural scientific knowledge accumulated in all branches of natural science, then we get a huge tome, perhaps necessary, but of little use even for specialists in the natural sciences, not to mention specialists in the humanities and socio-economic areas. The task of presentation is further complicated by the fact that its form must be accessible to students whose future professional activity has nothing to do with natural science. To solve this problem, a generalizing philosophical principle is needed. Its essence lies in the presentation of natural scientific knowledge within the framework of concepts - fundamental ideas and a systematic approach. The conceptual principle allows students to gain fundamental, complex knowledge about nature, and on their basis to study highly specialized disciplines more deeply.

Modern means of natural science make it possible to study many of the most complex processes at the level of atomic nuclei, atoms, molecules, cells, and then synthesize substances that did not previously exist in nature with unusual properties, and from them to produce new materials for various machines, devices, products, etc. In addition, thanks to such research, high-yielding cultivated plants are grown, highly effective treatments for diseases are developed, etc.

Any promising direction of human activity is directly or indirectly connected with a new material base and new technologies, and knowledge of their natural scientific essence is the key to success. Without fundamental knowledge about nature, an erroneous public opinion can form, leading to a biased decision, as happened, for example, with the unjustified announcement of a temporary (1975–1985) moratorium on genetic engineering. Consequently, natural science knowledge is needed not only for highly qualified specialists, but also for any educated person, regardless of the field of his activity.

In the pursuit of material values, modern humanity has already gone beyond the limits of the stable state of the biosphere, which includes all living things together with the environment. This means that as a result of the invasion of civilization in nature, a stable balance has already been disturbed, which for a long time ensures the circulation of substances. This is reminiscent of the destructive natural phenomena that have become more frequent over the past decade: hurricanes, tornadoes, floods, earthquakes, droughts, causing enormous material damage and accompanied by an increasing number of human casualties.

The transformation of a modern consumer society into a spiritually developed enlightened society is an extremely difficult task. It can be solved only by developing the entire education system by the common forces of educated people, for whom the guiding star is not luxury, not profit and other seductive idols, but the realm of goodness, freedom and truth. The noble but thorny path to such a kingdom begins with education by love in the earliest childhood, when the spiritual and moral foundation is laid for the assimilation of knowledge at all levels of education, and continues throughout the life of each person.

Knowledge does not come by itself. You have to work hard and study hard. “One must learn without being ashamed, and teach without being stingy,” as the well-known thinker Basil the Great (c. 330–379) said in ancient times, and only in this case can one hope for success.

PART I NATURAL SCIENCE AND THE MODERN WORLD

Learn, my son: science shortens our experiences of fleeting life...

A.S. Pushkin

For us, the science of natural science is the very lever that is the only one capable of turning the whole world towards the sun.

M. Gorky

1. NATURAL SCIENCE AND THE ENVIRONMENT
1.1. Natural science knowledge and education

History of the development of knowledge about nature. Throughout the history of the development of society, the basis of education was knowledge about nature, knowledge about man and knowledge about society. Obviously, these three components of education are interconnected: nature gave birth to man, and people make up society. According to the eminent Russian historian IN. Klyuchevsky (1841–1911), “the human personality, human society and the nature of the country are the three main forces that build human community ... The ideal of the historical education of the people consists in the complete and harmonious development of all elements of community life and in such a ratio in which each element develops and acts to the extent of its normal significance in the social composition, without belittling itself and without oppressing others.

The long history of the development of civilization shows that the named elements are far from always different in form and content. educational systems were in perfect harmony and constituted a harmonious unity. So, in ancient times, knowledge about nature - natural science knowledge - was descriptive, speculative, natural-philosophical in nature. The focus was on human knowledge.

The ancient Greek thinker Socrates (c. 470–399 BC) believed that main function knowledge is self-knowledge and intellectual, moral, spiritual growth of a person. His contemporary, the ancient Greek philosopher Protagoras (c. 480-410 BC), argued that the purpose of knowledge is to make human activity more successful and fruitful. However, both philosophers did not believe that knowledge is a direct path to skills and abilities. In those days, it was possible to master this or that craft from the master or by accumulating your own experience. Up to early XVIII in. in English language the concept of “craft” was expressed by the word mystery, meaning a sacrament, and not only because the one who possessed the secret of this or that craft swore an oath not to reveal secrets, but also because the craft was inaccessible to a person who had not been trained by a master and had not adopted it in practice experience.

In Russia already in the XIV century. a unique community of free masters, known as the “artel”, arose. Unlike similar communities in the West, the artel on Russian soil was not only and not so much a commercial association of narrow-profile craftsmen in the modern sense, but rather a community of fellow believers who professed Orthodoxy and observed the laws of freedom and justice. Being a peculiar form of social labor, the artel established the rules of life and influenced the character and behavior of everyone, repaying according to his deeds and the deeds of the surrounding family. The dignity of a person was evaluated, first of all, by belonging to one or another kind of masters.

The birth of technology. With the development of natural science knowledge, when, starting from the 18th century. the first fundamental laws of nature were discovered, followed by their practical application, the concept of "technology" appeared. It comes from the words techne - art, craft and logos - concept, teaching, which together means organized, systematized, purposeful knowledge.

Educational institutions were created to study technology. The first of these, the School of Bridges and Roads, was founded in France in 1747; followed by School Agriculture in 1770 and the School of Mining in 1776 (both in Germany). In 1794, a higher educational institution was opened in France - Politechnical University. It was the first technical university for the training of engineers. In previously founded higher education institutions, for example, in the oldest in Europe University of Bologna, opened in 1088 in Italy, non-technical and unnatural sciences were studied: mathematics, logic, philosophy, etc. Later, medical practice was also transformed into a systematized branch of scientific knowledge.

Entry into science and comprehension of technology in Russia was determined by the peculiarities of its nature and economic life, together with the temperament and mind of the Great Russians, which, according to V.O. Klyuchevsky, “they think and act as they walk; it seems that you can come up with a crooked and winding Great Russian country road? Like a snake crawled through. And try to go straight: you will only get lost and go out onto the same winding path. And at the same time, "not a single people in Europe is capable of such a strain of labor for a short time that a Great Russian can develop."

In the few chronicles and vaults found Ancient Russia natural phenomena were described: solar and lunar eclipses, northern lights, the movement of comets and the fall of meteorites, thunderstorms, storms, floods; technical information was given about the types and arrangement of weapons, the construction of fortresses and churches, the casting of bells and cannons, clockwork, the construction of bridges, etc. Moreover, astronomical phenomena were noted with “great accuracy”. Time has brought to us the name of the first Russian scientist, astronomer and mathematician Kirik of Novgorod, who wrote in 1136 the scientific treatise “Teaching by him to know the number of all years for a person”, which has no analogue either in ancient Russian, or in Byzantine, or in South Slavic literature. Feudal fragmentation, the Tatar-Mongol invasion and other factors held back the development of culture, science and education in Russia. If in Europe, after the invention of printing by I. Gutenberg (1399–1468), printing houses multiplied and books were printed on Latin, then in Russia at that time its own book printing was just being established, founded by Ivan Fedorov (c. 1510–1583), who in 1564 published the first Russian printed book, The Apostle. A radical change in the development of science, education and culture in Russia came under Peter I (1672–1725).

With the development of natural science knowledge in the West, and especially in Great Britain, inventions began to take root, and the craft of masters ceased to be a sacrament and a secret. The ascent to technology from crafts was largely facilitated by the publication of the first "Encyclopedia", compiled in 1751-1780. Denis Diderot (1713-1784), Jean d'Alembert (1717-1783) and others. In this greatest fundamental work, information about many types of crafts was presented in an organized and systematized form, which made it possible to obtain specialized knowledge without being hired as an apprentice. Scientific articles for the "Encyclopedia" were written by prominent scientists of that time - Voltaire (1694-1778), Rousseau (1712-1778), etc.

First technical schools and "Encyclopedia" solved the most important task for the development of science and technology - they brought together, systematized and made public the knowledge, skills and secrets of various crafts, transmitted earlier in oral from generation to generation for many centuries and even millennia. Practical experience they transformed into professional knowledge, practical training- in textbooks, secrets - in the methodology, and specific actions - in applied Science. All this contributed to the development of science, technology and industrial production.

Universality of education.“Three paths lead to knowledge: the path of reflection is the noblest path, the path of imitation is the easiest path, the path of experience is the most bitter,” said the ancient Chinese thinker Confucius (c. 551-479 BC). Without a doubt, this is how all branches of knowledge have always developed. However, if in ancient times the path of reflection prevailed, then in recent centuries experience, experiment and practice have become decisive - the most difficult, but effective way of knowing the world around us, leading to the development of natural scientific knowledge, and with them specialized, branch sciences to achieve concrete results that are useful not only to the individual, but also to society. What is now considered to be true knowledge is constantly proving its practical significance and is being tested by experience, in practice.

In the modern generalized view, knowledge is information that has practical value. Recently, in many countries there has been a transition to an economy based on the movement of not only traditional material resources and goods, but also new ideas and industry knowledge that make up informational resources. Information technology plays a decisive role in this. Thanks to their implementation, for example, in the United States, the annual increase in gross domestic product is more than 30%, or about 600 billion dollars, and according to this indicator, the information industry is ahead of the aviation and automotive industries.

However, the demon systems approach to mass consumption of information and its excess generate information chaos, which depends on many factors and, above all, on the education system. Time-driven striving for narrow specialization, multi-subjects in secondary and higher schools, oversaturation curricula, computer addiction and other "innovations" lead to the fact that not only teachers and teachers, but also their students - future specialists in different industries - like the builders of the Tower of Babel, cease to understand each other. At the same time, the universality and breadth of education are gradually being lost. Redundancy, excessive structuring of information and, together with them, information chaos turn away from knowledge and, as a result, cause panic and generate ignorance. “A society driven by panic turns away from knowledge and seeks salvation in ignorance,” Russian writer M.E. Saltykov-Shchedrin (1826–1889). With the loss of universality and breadth of education, the opportunity to acquire the practical knowledge necessary for the development of new technologies is lost.

In the last century, the isolation of natural-scientific and humanitarian knowledge began to be tangibly and clearly manifested, and a huge gap formed between them, which was reached in the 50s of the XX century. drew the attention of the English writer Charles Snow (1905-1980). In his opinion, society cannot survive without knowledge of the house in which it lives, or without knowledge about the world around it - without natural science knowledge. However, practically meaningful knowledge In domestic education in recent decades, due attention has not been paid by the state, which, by omission, gives preference to mass humanitarian education. Any society, fencing itself off from natural scientific knowledge, cannot coordinate its actions with the fundamental laws of nature, and especially if it loses spiritual and moral guidelines. This idea can be continued with the words of His Holiness Patriarch Alexy II of Moscow and All Russia (1929-2008): “I am convinced that no matter how much humanity has grown over the past century in its own eyes, it needs to sit down at the school desk again. We need to learn again that people have lost over the years the intoxication of their own strength and pride - to learn humility, the ability to ascetically limit their desires, obedience to the will of God, a moral way of life. Otherwise, all the achievements of science and technology will turn their force against us, and tower of babel human power will fall, burying its builders under the rubble. The hardest work for each of us will be not external, but internal. The gospel advises us to look first into ourselves.

Many researchers both in Russia and in other countries have come to understand the need for universality and fundamental nature of modern education based on knowledge about nature, man and society. They came in different ways and for different reasons. And they propose to solve this problem in different ways: some see a way out in the humanitarization of the natural sciences and technical education, and others - in the need to teach the natural sciences for students of humanitarian areas and specialties. At the same time, both come to a common opinion: the goal of studying all disciplines is the same - to ensure the future of human existence in the biosphere. However, a clearly defined goal does not define the means to achieve it. Indeed, the amount of information needed to study is extremely large. A legitimate question arises: is it possible to study it? And after him, another question: how to study it? It turns out that you can, if you use the conceptual principle that allows you to study the subject within the framework of fundamental ideas and a systematic approach. This fundamental principle of education is not only a subject of discussion, but also a guide to action in the presentation of the subject being studied.

Education at the turn of the millennium. Due to the growing anthropogenic impact on the biosphere and exacerbation environmental problem modern natural science education is becoming an effective means of mastering knowledge not only for solving many scientific and technological problems, but also for protecting the environment in order to save life on our planet.

For many centuries, the education system has been constantly improved and in our time allows for more short term receive a significantly larger amount of knowledge, which is constantly growing. If in the 1870s the volume of knowledge of all mankind increased approximately twice in a decade, in the 1980s - in 5 years, in the 1990s - every year, then at the beginning of this century this period was reduced to several months.

The development of education is the most important task of any state and humanity as a whole. In many countries, enlightened authorities are aware that investing in education - intellectual potential - is a profitable form of investment. However, the education system in different countries funded in different ways. For example, the annual cost of education per student in the USA is 18.57 thousand dollars, in Denmark - 11.60, in Spain - 6.03, and in Mexico - only 5.30 thousand dollars.

The rapid growth of the volume of new knowledge, subject to an exponential pattern, requires an increase in the effectiveness of training and an increase in its duration. Currently, the average duration of education in Europe is 15 years, in North America- 14 years old South America- 13 years, in Asia - 9.2 years, in Africa - 7 years and worldwide - an average of 10 years. It is assumed that in the coming decades, the duration of training required for a highly qualified specialist will approach 18 years. Despite the wide distribution of education, it does not cover the entire population of the globe, even at the primary level. According to UN statistics, about 3.5 billion people in the world today can read and write, which is about 3 times more than 40 years ago. At the same time, approximately 900 million adults can neither read nor write, and two-thirds of them are women. Adult illiteracy rates in many developing countries is more than 50%: in Nigeria - 80%, in Mali - 73%, in Iraq, Ethiopia and Bangladesh - 60%, in Pakistan - 58%.

Every year since 1990, the number of children in school around the world has increased by about 10 million, and today there are about 700 million. At the same time, more than 100 million children school age do not have the opportunity to sit at the school desk. Ensuring universal primary education is one of the priority tasks formulated in the UN Millennium Declaration.

The problems of education were discussed in 2006 at the G8 summit in St. Petersburg, where decisions were made on international cooperation aimed at improving the quality national education and its accessibility to the general population.

Only through a perfect education system, including spiritual and moral education, modern society will be able to preserve the natural environment and provide further development civilization.

Fruit domestic education . Not plunging into the wilds of history Russian education, it can be unmistakably argued that the education system has been reformed at all times, although this was not always necessary. There was no urgent need to reform education in recent decades. After all, with all the flaws of the former social structure and the utopianism of the communist ideology, in the recent past, an education system was established in our country, which made it possible for everyone to receive good knowledge.

The hasty, failed reforms that began in our country in the 1990s and are still ongoing under the sign of democratization, liberalization, humanization and other modernization have led not only to mass impoverishment Russian people and the enrichment of a small group of businessmen free from conscience, but also to a sharp drop in the level of education, which is now called the quality of education at the direction of ministerial officials. At the same time, the policy quality education turned into a policy of total delusion. As a result, knowledge has been devalued. Lost respect and honor teachers and teachers. Their wages have been drastically reduced. Blooming in luxuriant colors different forms paid “educational” services, under the guise of which many heads of so-called educational institutions profit, and teachers receive a miserable salary. Pupils stopped listening to teachers and parents, and students stopped listening to teachers. Terrible crimes are sometimes committed: teachers and professors, striving to give the most precious thing - knowledge, become a victim of the aggression of their ill-bred students.

The precious time of young people began to absorb various films and performances showing intimate relationships, computer games and especially the Internet with inexhaustible seductive services. Children began to show their latent abilities to write and draw more actively on the facades of houses, on the walls of schools and on desks. Some schools and universities have become dens of drug addicts. Smoking and even alcohol have come into fashion, to which children are introduced in their earliest childhood. And the result, as they say, was not long in coming: for children and adolescents, a lot of entertainment became available, where, under the guise of cultural recreation, young people are intoxicated, and in this muddy environment, many crooks make good money, arranging gatherings where all means are good: and powerful audio– and video equipment, and drugs, and alcohol.

Judging by the definition of education given in the Law of the Russian Federation “On Education” (education is education and training in the interests of a person, society and the state), the education process includes an important component - education. A good education can grow only on fertile soil with spiritual and moral guidelines strengthened by upbringing.

INTRODUCTION

Finally, I lend a hand to a truly useful science.

Horace

Every person, starting from a very early age, is distinguished by curiosity - a natural desire to know the world around him. “Curiosity is akin to a person both enlightened and wild,” said the outstanding Russian historian and writer N.M. Karamzin (1766–1826). With age, unconscious curiosity gradually develops into curiosity - a conscious desire to learn the laws that govern nature, to learn how to apply them in one's work, foreseeing its possible consequences. The laws of nature and the ways in which they are applied reflect the concentrated experience of mankind. Based on it, a person is able to protect himself from mistakes, and it is easier for him to achieve his desired goals. The concentrated experience of humanity underlies any educational process.

Natural science is a unified system of sciences about the laws, phenomena and properties of objects of nature, including many branches - the natural sciences.

The most important achievements of natural science form the fundamental basis of modern science-intensive technologies for the production of various products, including consumer goods. In order to know at what price such products are given - the most important component of the economy, what are the prospects for the development of modern technologies that are closely related to economic, social and political problems, we need fundamental knowledge about nature - natural science knowledge. In our time, natural scientific knowledge has become a sphere of active actions and represents the basic resource of the economy, which in its importance surpasses material resources: capital, land, labor, etc. Natural scientific knowledge and modern technologies based on them form a new image life, and a highly educated person cannot distance himself from fundamental knowledge about the world around him without risking becoming helpless in his professional activities. “Without the natural sciences, there is no salvation for modern man; without this healthy food, without this strict education of thought by facts, without this closeness to the life around us, ”the Russian writer and philosopher A.I. gave such a high assessment of natural science knowledge. Herzen (1812–1879).

If we set out in detail the natural scientific knowledge accumulated in all branches of natural science, then we get a huge tome, perhaps necessary, but of little use even for specialists in the natural sciences, not to mention specialists in the humanities and socio-economic areas. The task of presentation is further complicated by the fact that its form must be accessible to students whose future professional activities are not directly related to natural science. To solve this problem, a generalizing philosophical principle is needed. Its essence lies in the presentation of natural scientific knowledge within the framework of concepts - fundamental ideas and a systematic approach. The conceptual principle allows students to gain fundamental, complex knowledge about nature, and on their basis to study highly specialized disciplines more deeply.

Modern means of natural science make it possible to study many of the most complex processes at the level of atomic nuclei, atoms, molecules, cells, and then to synthesize substances with unusual properties that did not previously exist in nature, and from them to produce new materials for various machines, devices, products, etc. In addition, thanks to such research, high-yielding crop plants are grown, highly effective treatments for diseases are developed, etc.

Any promising direction of human activity is directly or indirectly connected with a new material base and new technologies, and knowledge of their natural scientific essence is the key to success. Without fundamental knowledge about nature, an erroneous public opinion can form, leading to a biased decision, as happened, for example, with the unjustified announcement of a temporary (1975–1985) moratorium on genetic engineering. Consequently, natural science knowledge is needed not only for highly qualified specialists, but also for any educated person, regardless of the field of his activity.

In the pursuit of material values, modern humanity has already gone beyond the limits of the stable state of the biosphere, which includes all living things together with the environment. This means that as a result of the invasion of civilization in nature, a stable balance has already been disturbed, which for a long time ensures the circulation of substances. This is reminiscent of the destructive natural phenomena that have become more frequent over the past decade: hurricanes, tornadoes, floods, earthquakes, droughts, causing enormous material damage and accompanied by an increasing number of human casualties.

The transformation of a modern consumer society into a spiritually developed enlightened society is an extremely difficult task. It can be solved only by developing the entire education system by the common forces of educated people, for whom the guiding star is not luxury, not profit and other seductive idols, but the realm of goodness, freedom and truth. The noble but thorny path to such a kingdom begins with education by love in the earliest childhood, when the spiritual and moral foundation is laid for the assimilation of knowledge at all levels of education, and continues throughout the life of each person.

Knowledge does not come by itself. You have to work hard and study hard. “One must learn without being ashamed, and teach without being stingy,” as the well-known thinker Basil the Great (c. 330–379) said in ancient times, and only in this case can one hope for success.

CONCEPTS OF MODERN NATURAL SCIENCE

Finally, I give a hand to a truly useful science.

Introduction

Any person has curiosity at a very early age - a natural desire to know the world around him. “Curiosity is akin to a person, both enlightened and wild,” said the outstanding Russian historian and writer Nikolai Karamzin (1766-1826). With age, the unconscious desire to know the world around us gradually develops into a conscious form of curiosity - the desire to know the laws that govern nature, and how to apply them, allowing a person to foresee the possible consequences of his actions. The laws of nature and the methods of their application are the concentrated experience of mankind, which forms the basis of the practical activity of man, capable of protecting him from possible mistakes and failures and helping to achieve the desired goals. The concentrated experience of mankind is the fundamental and necessary basis of any educational process: a person must know how the most complex system functions - the nature of the Earth is his only home, to which he owes his birth and part of which he himself is.
Natural science is the science of the phenomena and laws of nature. Modern natural science includes many natural science branches: physics, chemistry, biology, as well as numerous related branches, such as physical chemistry, biophysics, biochemistry and many others. Natural science touches upon a wide range of questions about the numerous and multifaceted manifestations of the properties of objects of nature, which can be considered as a whole.
If we set out in detail all the scientific material accumulated over a long period of time in all branches of natural science, then we get a huge tome, perhaps necessary, but of little use even for narrow specialists in the natural sciences, not to mention specialists in the humanities. The task of presenting the material of natural science is further complicated by the fact that its form should be accessible to future specialists, for whom natural science is not a discipline that forms professional knowledge.
To solve this problem, a generalizing philosophical approach is needed, taking into account advanced didactics methods based on the patterns of knowledge acquisition and the acquisition of skills and abilities. The essence of this approach lies in the presentation of natural science material at the level of concepts - fundamental ideas and systems of views. The conceptual systematic approach is useful not only for understanding the development of natural science itself and the phenomena and laws of nature studied by it, but also for getting acquainted with the most important achievements of natural science, on the basis of which modern science-intensive technologies are successfully developed that contribute to improving the quality of products and careful attitude to nature.
Many achievements of modern natural science, which form the basis for science-intensive technologies, are associated with a comprehensive study of objects and natural phenomena. With the involvement of modern technical means of experiment, it was precisely such a study that made it possible not only to create superstrong, superconducting, and many other materials with unusual properties, but also to take a fresh look at the biological processes occurring inside the cell and even inside the molecule. Most branches of modern natural science are connected in one way or another with the molecular study of certain objects, which unites many natural scientists involved in highly specialized problems. The results of this kind of research are the development and production of new high-quality products, and above all consumer goods. In order to know at what price such products are given - the most important component of the economy, what are the prospects for the development of modern science-intensive technologies that are closely related to economic, social, political and other problems, fundamental natural science knowledge is needed, including a general conceptual understanding of molecular processes, on which the most important achievements of modern natural science are based.
Modern means of natural science - the science of fundamental laws, natural phenomena and various properties of natural objects - allow us to study many of the most complex processes at the level of nuclei, atoms, molecules, and cells. The fruits of comprehension of true knowledge about nature at such a deep level are known to every educated person. Synthetic and composite materials, artificial enzymes, artificial crystals - all these are not only real objects of development of natural scientists, but also consumer products of various industries that produce a wide range of consumer goods. In this regard, the study of natural science problems at the molecular level within the framework of fundamental ideas - concepts - is undoubtedly relevant, useful and necessary for future specialists. highly qualified natural science and technical profile, as well as for those whose professional activities are not directly related to natural science, i.e. for future economists, management specialists, commodity experts, lawyers, sociologists, psychologists, journalists, managers, etc.
Recently, more and more often they are talking not about the chemical interaction of substances and increasing their chemical activity, but about changing the structure of a molecule, about breaking the chain of molecules, about the interaction of molecular beams, about connecting fragments of DNA molecules, etc. In the lexicon of specialists and scientific commentators-journalists, the words “molecule”, “molecular structure”, etc. And this means that the modern level of natural science reflects an understanding of the phenomena occurring in nature, as well as the processes observed in laboratories, taking into account the structure and behavior of each molecule. It is thanks to this understanding that substances that did not previously exist in nature with fundamentally new properties are synthesized, and new machines, devices, products, etc. are created from them, high-quality varieties of cultivated plants are grown, effective ways and remedies for diseases, etc.
At first glance, it may seem that this kind of knowledge is not needed at all, for example, by a future management specialist or a journalist. In reality, without them, a management specialist will not be able to choose a promising direction of his activity, because any business is somehow connected with a new material base and new technologies. Therefore, a management specialist, if he is a true specialist, must have deep and comprehensive knowledge. The same can be said about a journalist: without a deep understanding of the problem being commented on, a journalist is not able to correctly and in a popular form convey the most important scientific achievements to a wide range of readers. Not possessing necessary knowledge a journalist can erroneously orient public opinion and provoke a biased decision, as happened, for example, with the unjustified announcement of a temporary moratorium on genetic engineering (1975-1985).
It must be said that natural science knowledge with a conceptual understanding of the most important achievements of modern natural science is needed not only by future economists, lawyers, managers, entrepreneurs and other highly qualified specialists, but also by any educated person, regardless of the type of his activity.
Knowledge does not come by itself. One must work hard, study diligently, understanding freedom as a conscious necessity. “One must learn without being ashamed, and teach without being stingy,” the famous thinker Basil the Great (c. 330-379) said in ancient times, and only in this case can one hope for success.

Conclusion

Nature as an object of study of natural science is complex and diverse in its manifestations: it is constantly changing and is in constant motion. The circle of knowledge about it is becoming wider, and the area of ​​its conjugation with the boundless field of ignorance turns into a huge blurred ring dotted with scientific ideas - the grains of natural science. Some of them, with their sprouts, will break through into the circle of classical knowledge and give life to new ideas, new natural scientific concepts, while others will remain only in the history of the development of science. They will then be replaced by better ones. Such is the dialectic of the development of natural-scientific knowledge of the surrounding world.
One can speak about nature as a subject of natural science in a strict scientific language. One can also say about her simple words carrying deep meaning, as the German thinker and naturalist Johann Goethe did:
"Nature! Surrounded and engulfed by it, we can neither get out of it nor penetrate deeper into it... She captures us in the whirlwind of her dance and rushes with us until, weary, we fall out of her hands.
She always speaks to us, but does not reveal her secrets. We are constantly acting on it, but we have no power over it.
She is the only artist: from the simplest substance she creates the most opposite works, without the slightest effort, with the greatest perfection, and puts some kind of delicate veil on everything. She constantly thought and thinks constantly, but not like a person, but like nature, She has her own all-encompassing meaning ...
There are no number of her children. She is equally generous to everyone, but she has favorites, to whom she squanders a lot, sacrifices a lot. She takes the great under her protection.
Life is her best invention; death is for her a means to a greater life.
It surrounds man with darkness and drives him towards the light. Every act of hers is good, for everything is necessary; she tarries to be pursued; she hurries lest she be satiated.
She has no speeches and language, but she creates thousands of languages ​​and hearts with which she speaks and feels. Her crown is love. Love only approaches her. With one touch of her lips to the cup of love, she atones for a whole life of suffering.
She is harsh and gentle, loves and terrifies, weak and omnipotent. Do not snatch a declaration of love from her, do not lure a gift from her, unless she voluntarily gives. As she creates, so you can create forever.
.
