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. ... >>

Underground passages of old Europe 28.04.2012

The soil of Europe, from Hungary to Spain, is riddled with underground tunnels and adits of unknown purpose. Only in Bavaria (Germany) there are about 700 of them, in Austria - 500 and it is believed that 90% have not yet been discovered. There are many of them in Scotland and Ireland.

Often such a tunnel is only 20-50 meters long, the longest in Germany is 125 meters. They go down to a depth of 10 meters. On some you can go to your full height, on others - only by crouching, and there are also passages with a diameter of less than half a meter. They are found both under ancient cities and villages, and among untouched forests, where there has never been human habitation.

There are passages stretching under the cemeteries. There are those starting in the kitchens of old houses of medieval construction. But, although locals often consider tunnels as a means of rescuing the owners of castles during a siege, this is doubtful: the passages end in a dead end. A dead end may be a small cave with several niches in the wall, supposedly intended for sitting. In the walls of the passages there are smaller niches, where, apparently, the tunnellers, who worked with a pick, put a candle or an oil lamp. In some places in the catacombs, the remains of wooden doors with bolts were found. They, as well as coals found in some catacombs (apparently from torches) date back to the XNUMXth-XNUMXth centuries. None of the written sources of those times mention such structures.

The purpose of the tunnels remains mysterious. These could be places of detention of criminals. Or pre-prepared shelters from wars that shook the continent, or from roving gangs of robbers (but for this they are already very uncomfortable and lack an emergency exit). Or they are places for solitary religious meditation. And it is possible that the last adherents of the Druid religion, supplanted by Christianity, were hiding underground.
