But most of all it worries philosophers, sociologists, psychologists, educators. Let's try to understand the concept and role of professional duty, arguments confirming its social significance
By conducting an experiment, scientists were able to find out that during the construction of the pyramid of Cheops, the coordinates of the Earth's magnetic poles were strictly taken into account. A small error was found only in the length of its ribs. It is assumed that the ancient builders used the clues of nature, or rather, the moment of the autumn equinox

To understand how a hydraulic press works, let's remember the rule of communicating vessels. Its author Blaise Pascal found that if they are filled with a homogeneous liquid, then its level in all vessels is the same. In this case, the configuration of the containers and their dimensions do not matter. The article will describe several experiments with communicating containers that will help us understand the device and principle of operation of a hydraulic press
The physics of the structure of matter was first seriously studied by Joseph J. Thomson. However, many questions remained unanswered. Some time later, E. Rutherford was able to formulate a model of the structure of the atom. In the article we will consider the experience that led him to the discovery. Since the structure of matter is one of the most interesting topics in physics lessons, we will analyze its key aspects. We learn what an atom consists of, learn how to find the number of electrons, protons, neutrons in it
Work in physics is a value that is found by multiplying the module of the force that moves the body by the distance it has moved. In the article, we will consider in detail the situations when the body moves and remains motionless. We learn the formula of work and its units of measurement
Atmospheric pressure is the force with which air presses on the Earth, man and everything that surrounds him. The article will tell you how in the XVII century. with the help of the experiment, the force of air pressure was shown for the first time. It is very interesting! We will learn how atmospheric pressure is indicated and how it is measured
Not everyone knows that atmospheric pressure is different at different heights. There is even a special device for measuring both pressure and altitude. It's called a barometer- altimeter. In the article, we will study in detail how atmospheric pressure changes with height and what does air density have to do with it. Let's consider this dependence on the example of the graph
Since the force of gravity acts on a liquid, a liquid substance has weight. Weight is the force with which it presses on the support, that is, on the bottom of the vessel in which it is poured. Pascal's law says: the pressure on the fluid is transmitted to any point in it, without changing its strength. How to calculate the pressure of a liquid on the bottom and walls of a vessel? We will understand the article using illustrative examples
Atmospheric pressure is the force with which we are affected by the surrounding air, i.e. the atmosphere. The article will present experiments during which we will make sure that air pressure really exists. We will find out who measured it for the first time, what occurs with an uneven distribution of atmospheric pressure, and much more
Pascal's law for liquids and gases says that pressure, propagating in a substance, does not change its strength and is transmitted in all directions equally. Liquid and gaseous substances behave under pressure with some differences. The difference is due to the behavior of particles and the weight of gases and liquids. In the article we will consider all this in detail with the help of visual experiments
Pressure is a physical quantity that is calculated as follows: divide the pressure force by the area on which this force acts. The force of pressure is determined by the weight. Any physical object exerts pressure because it has at least some weight. The article will discuss in detail the pressure in gases. Examples will illustrate what it depends on and how it changes
The words "aviation" and "aeronautics" until the 20s. 20th century were synonyms. Everything changed at the beginning of the last century. Aeronautics began to be called movement with the help of devices that are lighter than air, and aviation - flying on airplanes. That is, ships that are heavier than air. In the article we will consider in detail the history of aeronautics, the physics of the process
Our perception of the pitch of a sound and its other properties is determined by the characteristics of the acoustic wave. These are the same characteristics that are inherent in any mechanical wave, namely the period, frequency, amplitude of oscillations. The subjective sensations of sound do not depend on the length and speed of the wave. In the article we will analyze the physics of sound. Pitch and timbre - how are they determined? Why do we perceive some sounds as loud and others as quiet? The answers to these and other questions will be given in the article
In the novel "The Secret of Two Oceans" and in the adventure film of the same name, the heroes did unimaginable things with ultrasonic weapons: they destroyed a rock, killed a huge whale, and destroyed the ship of their enemies. The work was published back in the 30s of the XX century, and then it was believed that in the near future the existence of a powerful ultrasonic weapon would become possible, the whole thing is only in the availability of technology. Today, science claims that ultrasonic waves as a weapon are fantastic
