What was called subbotnik before the advent of Soviet power?

Before the advent of Soviet power, the word "subbotnik" had a different meaning. So the high school students called the collective flogging, which was arranged for them by the authorities for misconduct committed during the school week. Corporal punishment itself was used in Russian schools until the second half of the 19th century.

Authors: Jimmy Wales, Larry Sanger

 Random interesting fact from the Great Encyclopedia:

How should one live in order to live as long as possible?

Longevity is largely determined by hereditary, genetic factors. But, like any inheritance, it can be quickly squandered, or it can be increased. Longevity statistics show that success is achieved mainly by "free children of forests and fields", leading a calm, measured lifestyle, engaged in moderate physical labor.

"Among the influences that shorten human life, sadness, despondency, fear, melancholy, cowardice, envy and hatred prevail... Boredom is very dangerous both physically and morally..." wrote the German clinician Christoph Wilhelm Hufeland . Excessive joy can lead to the same unpleasant consequences: Sophocles, for example, died to the applause of the crowd that crowned his genius, and the niece of the philosopher Leibniz died of joy, having found 600 thousand francs on her uncle's deathbed.

Trying to reconcile these two extremes, gerontologists propose to adhere to the golden mean - to avoid "excessive irritability" and, in general, "save nerve cells", since their performance decreases especially rapidly with age.

But it is known that people of active creative work also differed in longevity, whose nerve cells obviously worked extremely intensively. So, Leo Tolstoy died at the age of 82 from pneumonia. Titian died at the age of 99 from the plague; he was 95 years old when he completed his famous painting "Christ Crowned with Thorns". Camille Corot wrote one of his masterpieces in the 80th year of his life. Composer Daniel François Esprit Aubert died at the age of 90, and at the age of 87 he wrote the operetta "Dreams of Love". Goethe lived for 83 years, finishing the second part of Faust a year before his death. Literally exhausted himself with work, knowing neither rest nor peace, Michelangelo Buonarotti, but nevertheless lived for 89 years, leaving a unique mark in painting, sculpture, architecture and poetry. Ivan Petrovich Pavlov died of an infection at the age of 86, still full of creative energy.

A New Way to Control and Manipulate Optical Signals 05.05.2024

The modern world of science and technology is developing rapidly, and every day new methods and technologies appear that open up new prospects for us in various fields. One such innovation is the development by German scientists of a new way to control optical signals, which could lead to significant progress in the field of photonics. Recent research has allowed German scientists to create a tunable waveplate inside a fused silica waveguide. This method, based on the use of a liquid crystal layer, allows one to effectively change the polarization of light passing through a waveguide. This technological breakthrough opens up new prospects for the development of compact and efficient photonic devices capable of processing large volumes of data. The electro-optical control of polarization provided by the new method could provide the basis for a new class of integrated photonic devices. This opens up great opportunities for ... >>

Primium Seneca keyboard 05.05.2024

Keyboards are an integral part of our daily computer work. However, one of the main problems that users face is noise, especially in the case of premium models. But with the new Seneca keyboard from Norbauer & Co, that may change. Seneca is not just a keyboard, it is the result of five years of development work to create the ideal device. Every aspect of this keyboard, from acoustic properties to mechanical characteristics, has been carefully considered and balanced. One of the key features of Seneca is its silent stabilizers, which solve the noise problem common to many keyboards. In addition, the keyboard supports various key widths, making it convenient for any user. Although Seneca is not yet available for purchase, it is scheduled for release in late summer. Norbauer & Co's Seneca represents new standards in keyboard design. Her ... >>

The world's tallest astronomical observatory opened 04.05.2024

Exploring space and its mysteries is a task that attracts the attention of astronomers from all over the world. In the fresh air of the high mountains, far from city light pollution, the stars and planets reveal their secrets with greater clarity. A new page is opening in the history of astronomy with the opening of the world's highest astronomical observatory - the Atacama Observatory of the University of Tokyo. The Atacama Observatory, located at an altitude of 5640 meters above sea level, opens up new opportunities for astronomers in the study of space. This site has become the highest location for a ground-based telescope, providing researchers with a unique tool for studying infrared waves in the Universe. Although the high altitude location provides clearer skies and less interference from the atmosphere, building an observatory on a high mountain poses enormous difficulties and challenges. However, despite the difficulties, the new observatory opens up broad research prospects for astronomers. ... >>

Human liver grown in mouse head 05.07.2012

The scientists implanted liver tissue made from human skin stem cells into the head of a mouse and grew a tiny organ that already performs many of the functions of the liver. Scientists at the University of Yokohama have grown a tiny human liver inside a mouse. It remains to be seen whether the grown organ can perform all the functions of the liver, but if so, then medicine will have huge opportunities for unlimited production of donor organs.

In their work, the researchers used induced pluripotent stem cells from human skin, which developed into hepatic tissue progenitor cells. The scientists then added two more cell types - mesenchymal cells and vascular endothelial cells. As a result, without any scaffolding and scaffolding, the cells independently formed normal liver tissue about 5 millimeters in size. This tissue was then implanted into the head of a mouse, and the rodent was able to absorb some of the drugs that only the human liver can handle.

Thus, for the first time, it was possible to create a functional organ with a vascular system from stem cells, which opens up great prospects in transplantology. The cultured liver tissue was transplanted into the head of the mouse so that increased blood flow in this area could stimulate accelerated liver growth. Within just 48 hours, the tiny liver began to form human blood vessels and produce human proteins. The levels of glycogen and amino acids in the tissues were the same as those found in the human liver.

So far, the grown liver is not a perfect copy of the human one. Some "details" are missing, such as the bile ducts. It is also necessary to solve the problem of forming a large body of the correct form.
