Why did the first transatlantic telegraph cable last only a month?

The first telegraph cable, laid across the bottom of the Atlantic Ocean in 1858, was destroyed just a month after construction was completed. Wildman Whitehouse, who was then the chief electrician, applied too much voltage to him in an attempt to increase the speed of the signal.

What is American Football?

With the football that we are used to in Europe, this American version of the game has almost nothing in common.

Two teams of 11 players each play with a 6-gram leather egg-shaped ball with the aim of bringing it to the opponent's end zone and placing it on the ground there. For this so-called "touch" the team receives XNUMX points. The next points the team will receive if they manage to throw the ball over the crossbar of the opponent's goal or carry the ball over the end line.

Due to the allowed hard collisions of the players, their equipment includes helmets and protective pads for the shoulders and other vulnerable areas.

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. ... >>

Very sharp eye 10.03.2009

Specialists from the Institute of Vision in Paris are working on an artificial retina, which will consist of the thinnest diamond plate coated with microscopic light-sensitive transistors.

Diamond was chosen as the basis because it does not cause rejection reactions in the body, gets along well with nerve cells and has the properties of a semiconductor. Doctors hope to save vision with retinal degeneration with the help of a diamond.
