When and why did the tenth pin appear in bowling?

In the 19th century, the game of bowls with 9 pins appeared in the USA and gained such popularity that spectators began to place bets. The authorities of some states banned the game, then the players added a tenth pin to bypass the ban and gave the game a new name - bowling.

How did the gift of Soviet schoolchildren to the American ambassador in 1945 help our special services?

In 1945, Soviet schoolchildren presented the American ambassador with a wooden panel made of precious woods depicting the US coat of arms. Neither the schoolchildren nor the ambassador knew that a listening device was installed in the panel, the design of which was developed by Lev Theremin. The "bug" was so well hidden that the American secret services did not notice anything, and the Soviets listened in on conversations in the ambassador's office for another 8 years. After the discovery, the device was presented to the UN as evidence of the intelligence activities of the USSR, but the principle of its operation remained unsolved for several more years.

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. ... >>

Sleep learning secret revealed 03.11.2022

It is well known that in order to consolidate new information received during the day, you need to "sleep" with it. During the night, all knowledge and impressions will subside and be deposited in memory. A similar process is even reflected in folk proverbs and sayings. However, until now, scientists have remained a mystery of what exactly happens in the brain and how to explain this phenomenon.

To unravel this mystery, researchers at the Pennsylvania State University (USA) conducted a series of experiments in which volunteers slept in the laboratory, and scientists recorded changes in their brain activity. As a result, based on these data, a computer model of the activation of neural networks during sleep was built.

Scientists have found that as the brain goes through slow-wave sleep and rapid eye movement (REM) sleep, which happens about five times a night, one region of the brain, the hippocampus, "teaches" another region of the brain, the neocortex, with the information received during wakefulness. knowledge. Through this process, new ephemeral information is transformed into lasting memories.

The hippocampus is responsible for episodic memory, while the neocortex is responsible for speech, thinking, and other functions of higher nervous activity. During slow wave sleep, the hippocampus communicates with the neocortex and transmits new data to it, and during the REM phase, the neocortex fixes the received information in long-term memory.
