How was camel dung used against German tankers?

While in the North African theater of World War II, German tank crews started a tradition of running over piles of camel dung "for good luck." Seeing this, the Allies made anti-tank mines disguised as these piles. After several of them worked, the Germans began to avoid untouched manure. Then the allies made mines that looked like heaps of manure with traces of caterpillars that had already run over them.

How did Roentgen discover the radiation later named after him?

On November 5, 1895, the German physicist Wilhelm Conrad Roentgen (1845-1923) conducted an experiment to study the luminescence caused by cathode rays. To make the effect clearer, he not only placed the cathode ray tube and the luminescent substance in a black cardboard box, but even tightly curtained the windows in the laboratory.

Turning on the cathode ray tube, Roentgen suddenly saw a flash of light in the other half of the room. It turned out that the light came from a sheet of paper coated with barium platinocyanide, a luminescent substance. Roentgen was very surprised: how could the radiation penetrate the walls of the box and cause the paper to glow? He turned off the cathode ray tube - the glow disappeared. Turned on the receiver again - the glow appeared again. X-ray moved the paper to another room - it continued to glow. It became clear to the scientist that a certain form of radiation arises in the cathode ray tube, capable of penetrating not only through cardboard, but also through walls.

Roentgen had no idea about the nature of these rays, so he called them X-rays (X-rays). Already other scientists began to call them X-ray.

For the discovery of these rays, Roentgen was awarded the Nobel Prize in Physics in 1901.

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. ... >>

Artificial vision system based on the body of a fiddler crab 04.08.2022

Current artificial vision systems have some limitations: they are not suitable for imaging both terrestrial and underwater environments and are limited to a hemispherical (180°) field of view.

To solve these problems, a team of researchers from Korea and the United States, including Prof. Yang Min-song from the Gwangju Institute of Science and Technology in Korea, has developed a new artificial vision system. It is equipped with an omnidirectional imaging capability that can operate in both aquatic and terrestrial environments.

The system was inspired by the fiddler crab (Uca arcuata), a species of semi-terrestrial crabs with a 360° field of view. It is possible due to the ellipsoidal stem of the compound eyes of the crab, which makes it possible to obtain panoramic images of amphibians. In turn, flat corneas with a graduated refractive index profile enable the crab to view images of amphibians.

Accordingly, the researchers developed a vision system that consists of an array of flat microlenses with a graduated refractive index profile. They were integrated into a flexible comb array of silicon photodiodes and then mounted on a spherical structure.

The gradient refractive index and the flat surface of the microlens were optimized to compensate for defocusing effects due to changes in the environment. Simply put, light rays that pass through different media (corresponding to different refractive indices) are focused in the same place.
