Why do photographers say: A bird will fly out now !?

Previously, in order for all the children in a group photo to look into the lens, photographers said: "Look here! A bird will fly out!" This bird was quite real at the beginning of the era of mass photography - though not alive, but brass. In those days, cameras were far from perfect, and in order to get a good picture, people had to freeze in one position for several seconds. In order to attract the attention of restless children, the photographer's assistant at the right moment raised a brilliant "bird", which, moreover, already knew how to make trills.

 Random interesting fact from the Great Encyclopedia:

What animals were the inhabitants of the Augean stables?

In one of his exploits, Hercules cleared the stables of King Avgii, from which no one had removed manure for thirty years, breaking the wall around them and directing the channels of two rivers there. In this classic story, a terminological inaccuracy is less known: the main inhabitants of the "stables" were not horses, but several thousand bulls, so it would be more appropriate to call them barns. However, it was the "Augean stables" that became a catch phrase, meaning an extreme degree of disorder.

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. ... >>

Microplastics at the bottom of the ocean are more dangerous than on the surface 28.04.2020

Every year, humanity adds an additional to the main amount of plastic pollution in the world's oceans, thus creating an even greater problem of plastic pollution than previously discussed.

A team of ecologists from the University of Manchester has shown that microplastics - representing the main threat to marine and ocean ecosystems in this context - can accumulate not only on the surface of the water, forming a kind of islands, but also accumulate in rather large piles in the deep layers of the ocean, even more complicating the environment.

The specialists took the Mediterranean Sea as the basis for the comparison model, where they compiled their map of plastic pollution - they found that microplastics tend to accumulate in those parts of the deep layers of water that are formed by undercurrents, which, along with garbage, also carry oxygenated water and various kinds of important trace elements for maintaining the normal life of the marine ecosystem.

It is the underwater heaps of microplastics that have a more pronounced threat, since they are formed unevenly and almost always chaotically, which not only complicates the ability to predict the place of their subsequent appearance, but also directly eliminate them from under the water. At the same time, according to the researchers, most of this microplastic is made up of various fabric materials that previously served as the basis for clothes, shoes and other similar products, which are often thoughtlessly thrown out by people.

Microplastics have another feature, namely the ability to accumulate in the most active regions in terms of the underwater ecosystem, thus posing a greater threat for a much longer time. It remains only to wait for the next stage of the study, when experts should identify the real indicators of the current microplastic pollution in the Mediterranean Sea.
