What is a dream?

Dreams have interested, frightened, and puzzled people for millennia. Dreams were given the strangest explanations. At one time, people believed that the images appearing in a dream were a message from the gods. It was believed that the source of dreams was located somewhere outside the sleeping person and that only people with special skills could understand dreams.

In our time, it is believed that dreams occur in the sleeper himself. And since dreams belong to the sleeping person himself, they can have a special meaning for him. The fact that you see this or that dream may depend on many reasons. Your dreams may be affected by your state of health. A sick or unwell person will have dreams that are different from those of a healthy and cheerful person.

If someone is cold, tired, hungry, then his dreams will be associated with this feeling. Therefore, many dreams can be very unpleasant. The events of the past day can also be of great importance for the content of the dream. Often those people and events that you see in a dream are the same that you met during the day. Your emotions can also greatly affect your dreams.

In a dream, your desires and needs, as well as fears, can be expressed. Feelings of joy or disappointment that appear in a dream have manifested themselves in this person, apparently, before. Sleep just gives them an outlet.

Random interesting fact from the Great Encyclopedia:

Why is it cooler at the top of the mountain?

Our atmosphere is divided into layers, they are all different from each other. The main layers are called the troposphere, stratosphere and ionosphere. Together they form a cover several kilometers thick. The troposphere is the lowest layer of the atmosphere where we live. The upper limit of the troposphere is at an altitude of 11 m above sea level. Above the tropics it is higher (000-16 km), above the poles it is lower (18-8 km).

Instruments raised on balloons prove that the temperature in the troposphere is gradually falling. The higher you go in the troposphere, the colder the temperature becomes. Every 300 m the temperature drops by 2 °C. So when we go up in the mountains, we go up in the troposphere. Therefore, at an altitude of 1,5 km in the mountains it can be 8 ° C cooler than at the foot.

And there are peaks that reach a height of more than 8 km! No wonder it's very cold there. In the upper troposphere, the temperature is almost 60 degrees below zero. It is always warmer near the surface of the Earth. The reason is that the Sun heats the Earth and the Earth releases this heat into the air. The sun does not heat the atmosphere directly. In the highest layer, the ionosphere, the air is rarefied, atoms and molecules are exposed to solar radiation.

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

Robot on the road 15.08.2019

In order to unload traffic in large cities and prevent as many accidents as possible, the Chinese authorities have sent robots to help people, designed to keep order on the roads.

China is increasingly integrating high technology into the protection and services of citizens in large cities. Now we can add another miracle of modern engineering to this list - a police robot.

The Handan Public Security Bureau in North China has deployed three types of transport robots to assist human officers. In a report from state-run Xinhua news agency, Zhou Zuoying, deputy head of the Traffic Management Research Institute under the Ministry of Public Security, said the deployment of the bots marks the first use of "robo-traffic police" in China.

Each of the three types of robots looks slightly different than the others and will perform unique functions that the Global Times - another government publication - has detailed in a separate report.
The first type is the "highway patrol robot" designed to look like a traffic officer in a yellow uniform and white helmet. This bot is able to identify drivers and photograph traffic violations.

The second is a "traffic advisory robot". It will be placed at vehicle control stations, where it will answer residents' questions and direct them to the right place. It will also alert authorities to any potential security threats or suspects.

The third type is the "emergency warning robot", designed to let drivers passing by know that an accident has occurred and they need to be more careful on the road.

The robots will be on duty 24/7, said Handan Public Security Bureau spokesman Li Huai. However, it is not yet clear whether we are talking about all the robots at the same time, or whether they will be on duty in shifts. It is worth noting that this is far from the first experience of using robots for the benefit of Chinese citizens. In 2016, the AnBot security robot stepped in to bypass Shenzhen Airport, and in 2017, the E-Patrol Sheriff robot began patrolling the streets.
