Which aircraft device completely contradicts its slang name?

The flight recorder, which is installed on aircraft to record information about the technical condition of all devices, as well as the actions and conversations of the crew, is often called the "black box". Although in fact this device does not have the shape of a box, but a ball or cylinder, and its color is not black, but red or orange, so that it is easier to find in case of an accident.

Authors: Jimmy Wales, Larry Sanger

 Random interesting fact from the Great Encyclopedia:

How did the handshake come about?

Today, when meeting or parting, a handshake is considered quite natural. But, probably, many things that we do without thinking were once very symbolic. In primitive life, for example, the hand could be a symbol of power and strength. It was used in battles with enemies, hunting, for the manufacture of weapons and tools. Thus, a hand extended towards another person could symbolize peaceful intentions, since this gesture began to mean the absence of weapons or the desire to fight.

It is known that gesticulation was important in ancient religion, for example, as a sign of power. The Greeks prayed to their gods with their hands up. At one time, a sign of respect for elders was a gesture, which was a combination of hands palm to palm. Once among the Arabs there was a custom to kiss the hands of the elders. Later, polite Arabs began to resist those who wanted to kiss their hands. They tried to get ahead of the kiss by shaking both hands at the same time.

The ancient Greeks offered their right hand when they wanted to express friendly feelings to a stranger. Thus, for centuries, the human hand and gestures have had a lot of meaning. And when we, without hesitation, shake hands with each other, in fact, we continue the tradition that has come down to us from antiquity.

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. ... >>
