The stellar universe is fraught with many mysteries. According to the general theory of relativity (GR), created by Einstein, we live in a four-dimensional space-time. It is curved, and gravity, familiar to all of us, is a manifestation of this property. Matter bends, "bends" the space around it, and the more, the denser it is

Solutions are a homogeneous mass or mixture consisting of two or more substances, in which one substance acts as a solvent, and the other as soluble particles
Gas has a high reactivity compared to liquid and solid bodies due to the large area of its active surface and the high kinetic energy of the particles forming the system. In this case, the chemical activity of the gas, its pressure and some other parameters depend on the concentration of molecules. Let's consider in this article what this value is and how it can be calculated

Lightning can be attributed to the most mysterious and dangerous natural phenomena. There are many types of these natural discharges. Although they differ from each other, but without exception, they all have the most powerful destructive power
The article provides general information about the structure of the atom and the algorithm of chemical reactions (examples are given)
Kinematic viscosity is a fundamental physical characteristic of all gas and liquid media. This indicator is of key importance in determining the drag of moving solid bodies and the load that they experience. As you know, in our world, any movement occurs in the air or water environment
The concept of "chemical reaction" is the second main concept of chemistry. Every second, an innumerable number of reactions take place in the world, as a result of which one substance turns into another. We can observe some reactions directly, for example, the rusting of iron objects, blood clotting, and the combustion of automobile fuel. At the same time, the vast majority of reactions remain invisible, but they determine the properties of the world around us
What branches of physics are there, and what physical processes are the subjects of their study? You will find the answer in this article
This article describes the wave function and its physical meaning. We also consider the application of this concept in the framework of the Schrödinger equation
In statistics, groups of individual data points can be classified as belonging to any of the various types of statistics. For example, categorical type ("red", "blue", "green"), real number (1.68, -5, 1.7e + 6), odd number (1.3.5), etc. Statistical data is also called statistical information
Scientific and technological revolution (NTR) characterizes the current level of scientific and technological progress, a feature of which is the rapid development of fundamentally new industries and the discovery of previously unknown laws of nature. Moreover, the result of success is not only technological developments, but also the expansion of theoretical knowledge. There are different stages of scientific and technological revolution, which have their own character, features of development and influence on the further course of progress
Psychology is a field of knowledge about the inner world of animals and humans. There are several stages in the development of psychological science: about the soul, about consciousness, about the psyche, about behavior
Scientific knowledge can be divided into two levels: theoretical and empirical. The first is based on inferences, the second is based on experiments and interaction with the object under study. Despite their different nature, these methods are equally important for the development of science
The history of pedagogy is rooted in the distant past. Together with the first people, education also appeared, but the science of this process of personality formation was formed much later
What is lymph? What functions does it perform in the human body? How does it affect us and our activities?
Psychophysiology is the science of the physiological foundations of behavior and mental activity. This article provides basic information about it. You will learn the history of its origin, the features of the methodology, its significance, as well as some other important information about this science
The upper limb of a person played an important role in the evolutionary formation of it as a biological species. In our article, we will consider the parts of the human and animal hand, the features of their structure and functioning
The evolution of stars, depending on their mass, occurs in different ways. Astronomers believe that a stellar black hole is formed due to the collapse of a very massive star. Over time, it burns out hydrogen, then helium, and then the moment "x" comes, when the severity of the surface layers can no longer be balanced by internal pressure and the process of strong compression of the mass begins
One of the most progressive US states - California - is seriously considering a law that recognizes the existence of such a sex as a non-binary, which is, in fact, a third gender. This is due to the appearance of the world's first asexual man
Many people think that muscle strength directly depends on their volume. To some extent, this is true. But there are seven other factors that together allow a person with a small amount of muscle to outperform a larger opponent in strength disciplines. Let's find out what these factors are

The law of homologous series, discovered by Vavilov, is comparable in its importance in selection to Mendeleev's periodic system of elements in chemistry. About what is its essence and meaning - read in the article
Theory of learning is an independent part of the science of pedagogy. It is also commonly called didactics (from the Greek "didacticos" - educating, instructing). Teachers in the schools of ancient Greece were called didascals, since they were entrusted with the responsibility not only to give young people certain knowledge, but also to educate them as real citizens. Gradually, in the colloquial language, this concept acquired a contemptuous meaning: “the desire to teach everyone, to overly moralize”
Three-dimensional space is a geometric model of the world in which we live. It is called three-dimensional because its description corresponds to three unit vectors having a direction in length, width and height
