When could architects or musicians win Olympic medals without playing any sport?

From 1912 to 1948, Olympic medals were awarded not only to athletes, but also to artists. As early as the end of the 19th century, Pierre de Coubertin, proposing to revive the Olympics, expressed the idea that it was necessary to compete both in sports disciplines and in various fields of art, while the works should be related to sports. There were five main medal nominations in total: architecture, literature, music, painting and sculpture. However, after the 1948 Olympics, it became clear that almost all participants in such competitions were professionals who earn money from art, and it was decided to replace such competitions with simply cultural exhibitions.

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. ... >>

Super low sounds make people dance 21.11.2022

Rhythmic sounds at frequencies beyond the range of human hearing affect listeners. Experiments with the Canadian band Orphx showed that extremely low basses stimulate the audience to dance, although they are not perceived by consciousness.

"Music is a biological mystery: it's not needed for reproduction, nutrition or survival, but why do people love it so much and love to move to it so much"? asks Daniel Cameron. Together with colleagues from the Canadian McMaster University, he explores the effect of music on our nervous system. In their new work, scientists have found that even ultra-low frequencies lying on the verge of hearing imperceptibly affect listeners, stimulating them to dance and move more actively.

The impact of music on a person is unexpected and varied. Many of its aspects are related to personal experience and familiar culture, but others are universal. It is not for nothing that representatives of any peoples perceive the same melodic phrases all the same - let's say, as sad or invocative, triumphant. There are also mysterious manifestations such as memory improvement while listening to well-known songs.

Especially for music research at McMaster University, a "laboratory" concert hall LIVELab is arranged. It is equipped with motion capture cameras and sophisticated Meyer acoustic equipment capable of reproducing the entire spectrum of frequencies accessible to the human ear (approximately 20 to 20 thousand hertz), as well as beyond this range. To participate in new experiments, Cameron and his colleagues invited the popular duet Orphx, working in the genre of electronic dance music.

Volunteers who came to the concert were given sensors to better track their movements. In addition, they completed questionnaires before and after the 55-minute duet performance. And during it, scientists imperceptibly changed the settings of the acoustic equipment: every 2,5 minutes they turned on and off the speakers that reproduced ultra-low bass frequencies from eight to 37 hertz.

Experts compared the intensity of the movements of the public during these intervals. It turned out that when the ultra-low bass sounded, the audience moved an average of 11,8 percent more actively than when they were not present. At the same time, the questionnaires showed that no one noticed any difference by ear: the frequencies were too low.

The reasons for this are not exactly known. The authors of the study suggest that the effect may be due to the direct influence of ultra-low frequencies on the brain, bypassing conscious perception. The structures of the inner ear are closely integrated into the functioning of the vestibular apparatus and the motor system. Perhaps their vibrations are able to be directly reflected in the work, without involving the ear.
