Why do Mexicans call Americans gringos?

One of the nicknames for Americans is gringo, especially often they are called that way in Mexico and other countries of Latin America. The term originated in Spain, where it was used for any foreigner who did not speak Spanish well. In all likelihood, the word "gringo" comes from "griego", that is, "Greek", which brings it closer to the English idiom regarding the incomprehensible speech "Greek to me".

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. ... >>

Nanoparticles in silk 25.10.2009

Chemists from the USA have learned how to encrust silk with silver nanoparticles. Precious metal ions have the ability to precipitate from solution on biological fibers and recover to pure metal, forming nanoparticles associated with these fibers. In this case, it is possible to solve two problems: to prevent nanoparticles from sticking together and to evenly distribute them over the volume or surface of the material.

It was this ability of theirs that scientists from the Georgia Institute of Technology, led by Professor Vladimir Tsukryuk, took advantage of. They dissolved silkworm cocoons and the resulting solution was applied as a thin film on a silicon substrate. Then, a template pattern was drawn on it by nanolithography and placed in a solution containing silver ions.

After a few days or even weeks, nanoparticles were deposited on the silk, and a flexible elastic film of the composite was obtained with a thickness of only 100 nm. Its obvious use is a bactericidal dressing, containing, although an insignificant amount of silver, but this does not lose its effectiveness.

However, the authors believe that it can be used to make flexible mirrors that reflect light at a certain wavelength, as well as self-cleaning coatings, catalysts, and possibly flexible batteries. “If we mix proteins that can combine with both gold and silver, then it will be possible to obtain a composite of nanoparticles of the two metals. Since their properties differ, this will be a very interesting material,” says Yevgenia Kharlampieva, a participant in the work.
