How did the Norwegian national anthem save one Jew from being captured by the Nazis?

In 1941, during a concert of the Philharmonic Orchestra in Norway, a group of Nazis broke into the hall. Their goal was to capture the violinist with Jewish roots, Ernst Glaser, and hand him over to the German occupation authorities. However, conductor Harald Heide immediately ordered the musicians to play the national anthem of Norway, which caused confusion among the attackers and allowed Glaser to escape through the wings.

What are psychic phenomena?

Sometimes things happen to people that are out of the ordinary. This does not mean that these phenomena are supernatural. Science just can't explain them yet. They are called psychic phenomena. There are many varieties of such phenomena, and people study them with great interest. Many people believe in them, others don't.

Let's look at some of these phenomena. One of them is called "poltergeist". It is associated with strange sounds, the movement of furniture, breaking dishes and other strange incidents that people who are at that moment in the apartment cannot explain in any way. But for this to happen, the presence of a certain person is almost always necessary.

Even more interesting are the phenomena associated with the extraordinary abilities of the psyche of some people. In such cases, a person has knowledge about what he could not know in any natural way. For example, he can read the thoughts of another person or learn about an event that happened somewhere far away or a very long time ago.

Reading the thoughts of another person (not a guess, but reading) is called telepathy.

Knowledge about some distant and long-standing incidents is called clairvoyance. A lot of research has been done to prove the existence or demonstrate cases of telepathy, but many scientists claim that these experiments were done incorrectly. Another interesting psychic phenomenon is called prediction. This is when people seem to know about events that should happen in the future. People who do not believe in predictions may ask why these people do not get rich on the stock exchange or do not prevent crime.

In general, there is a twofold attitude towards psychic phenomena: some unconditionally believe in them, and others - among them there are many scientists - do not believe in them and believe that such a thing cannot take place and therefore does not happen.

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 ... >>

The songs of whales will help in the study of the geology of the seabed 17.02.2021

Geologists have discovered that the low-frequency acoustic signals of whales are able to penetrate into the thickness of the earth's crust, and the signal reflected from it allows you to "enlighten" rocks deep below the ocean floor.

Blue whales and fin whales close to them communicate with "songs", emitting the lowest frequency sound waves in the entire animal kingdom - from 16 to 40 hertz. Such waves can reach an energy of 189 decibels, spreading far in the water and even penetrating deep into the sedimentary rocks at the bottom of the sea. The signal reflected by the earth's crust can be registered by obtaining new information about the structure of the earth's crust in a particular part of the ocean.

This proposal was made by John Nabelek and Vaclav Kuna from the Institute of Geophysics of the Czech Academy of Sciences. Scientists have demonstrated in practice that vocalizations of fin whales can serve as tools for studying the structure of the oceanic crust.

The authors used recordings of six songs of the same fin whale made in the northeast Pacific Ocean in 2012-2013. Each of them lasted from 2,5 to 4,9 hours, and acoustic signals were captured by a network of 54 seismometers installed in the region. Signals reflected from the parts of the earth's crust lying below the bottom were also recorded. Layers of rock with different properties affect the reflection and movement of acoustic waves in their own way, making it possible to reconstruct the internal structure of the lithosphere.

Specialists actively use such vibrations created by crustal movements and earthquakes. However, the songs of the whales turned out to be powerful enough to "shine through" the lithosphere. Nabelek and Kuna showed that the collected recordings of the whale's songs made it possible to see the bottom along the way. In this case, it turned out to be quite typical: from 400 to 650 meters of sedimentary rocks, a 1,8-kilometer layer of solid basalt, below which the gabbro of the underlying layer of oceanic crust begins.
