How fast are the trains?

The French TVG from Paris to Lyon has a speed of 260 km/h. In a test flight without passengers, he reached a speed of 515 km / h.

Japanese trains are even faster. On the segment between Tokyo and Osaka, the speed of the train reaches 300 km/h.

The fastest freight trains also run in France. Fresh vegetables are delivered from Perpignan to Paris at a speed of 140 km/h.

The longest railway is the Trans-Siberian Railway with a length of 9438 km. The entire flight from Moscow to Nakhodka lasts 8 days and 4 hours. It stops at 97 stations along the way. And the longest direct railway is in Australia. For 478 km there is not a single turn.

Random interesting fact from the Great Encyclopedia:

Why do hot objects cause burns?

We have all experienced that fire and hot objects cause a painful sensation. The child does not know this - and gets burned. We are learning from our own experience.

In a hot iron, the atoms vibrate at a tremendous frequency - perhaps up to a million vibrations per second! If we touch the iron with the tip of our finger, we will feel pain, as the fast moving particles will cause our skin molecules to move sharply and quickly as well. You will feel this rapid movement as pain - that's why hot objects burn.

You can imagine how fast the molecules must move in order for the skin to get this feeling. Let's take this comparison as an example. At the melting temperature of ice, which is not hot at all, hydrogen molecules move at a speed of more than 1700 m/sec!

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. ... >>

Elevator test tower 05.11.2010

The rapid construction of skyscrapers in China and the Arab countries has caused a great demand for elevators. The Japanese firm Hitachi, one of the world's leading manufacturers of lifting machines, has built the world's tallest elevator test tower.

Its height above the ground is 213 meters, and the underground floors go deeper by another 15 meters. The tower has nine elevator shafts. A new elevator will be tested here, capable of delivering 60-70 passengers to a height of up to 1080 meters per minute (such tall buildings do not yet exist, but the company is looking ahead), as well as a five-ton freight elevator, developing a speed of 600 meters per minute.

Hitachi's new high-speed elevators have a system for smoothly changing the air pressure in the cabin so that passengers do not get stuffy in their ears during a quick rise.
