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. ... >>

Calculated the total amount of light emitted by the universe 29.11.2018

Our Universe - at least that part of it that we know - has been creating and transforming stars and other cosmic bodies for 13 billion years. And if earlier astronomers were very interested in the question of how many stars existed during this time, then at the moment they are more interested in the mystery of how much light these stars emitted. Using a new method to systematically count the light from blazars, a NASA team today came up with this figure, which in itself seems quite huge and one can only guess what it is in the context of a part of the universe that is not yet accessible to us.

Having made simulation calculations for the last 13 billion years, scientists got a figure of 4x10^84 - this means that after the number 4 there are 84 zeros, which is 4 septenvigintillion light rays. However, readers will probably have a question about how, in a fantastic way, scientists managed to get such a number? In fact, there is nothing particularly fantastic here - they simply used data from the super-powerful Fermi Gamma telescope over the past nine years and analyzed how gamma rays from blazars interact with the so-called "cosmic fog", at the output they found the total amount of light produced by stars.

This fog - known as extragalactic backlight - is made up of all the light produced by stars across the entire ultraviolet and infrared wavelength spectrum. When gamma rays pass through the fog, they collide with other light waves, they produce positrons and electrons.

By studying the signatures of these elements from gamma rays from more than 739 blazars, astronomers have been able to measure the fog's density at any viewable point, as well as at any time point in its progress and development - not without the help of computer simulations, of course. Thus, the new improved measuring method allows you to measure the most accurate and hidden indicator of the Universe, revealing its mysteries and secrets.
