Why was the ship's bell called a rynda?

Initially, the word "rynda" appeared in Russian to designate a squire-bodyguard of the tsar on campaigns. In the meaning of the ship's bell, the rynda began to be used later. This happened as a result of the Russification of the English ship command "ring the bell" ("ring the bell"). Our sailors turned it into a "rynda bey", so the bell became a bell.

What invention did the US military demonstrate in 1881 by blowing up this donkey?

In 1878, a technology was invented that made it possible to capture a frame on photographic film with almost no delay. After 3 years, an employee of the American military institute was given the task of destroying the useless donkey, and the military decided to do it for the "benefit for science" - to blow up the donkey's head and fix it with a quick picture. The detonator of the donkey-tethered explosive was simultaneously connected to the camera shutter. The experiment was a success: the device clearly recorded the moment of the explosion of the donkey's head.

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. ... >>

Fill your cell phone with syrup 04.05.2007

US scientists have created a polymer battery that runs on a sugar solution. A portable fuel cell is something that should replace a regular cell phone or laptop battery.

However, so far, methanol claims to be the fuel for it - a poisonous and inaccessible substance. At the same time, there is always another source of energy at hand - sugar. Therefore, the idea of making an element that runs on a solution of sugar seems very attractive. Bacteria usually produce electricity from sugar.

Scientists from St. Louis University, led by Dr. Shelley Minteer, decided to go further. Why feed an entire bacterium, when it is enough to take the only enzyme that breaks down a sugar molecule and is able to transfer the electron obtained in the process to the electrical network?

They sewed this enzyme, NAD-dependent glucose dehydrogenase, together with the mediators accompanying its work, to a membrane of chitosan, which, in turn, is obtained from the chitinous shells of crustaceans and insects. Such a biological complex was placed on a glass electrode and used to make a battery that worked stably for a month on a systematically added sugar solution.

“It was the regular sugar solution that gave the best results,” says Shelley Minteer. “We also tested tree sap, sweet drinks, glucose solution. All of them showed good results. But soda reduced power, which was to blame for carbon dioxide. biodegradable batteries that will last several times longer than current cell phone and laptop batteries."
