What was the main reason for the transition to a time zone system in the 19th century?

Until the 19th century, there was no division into time zones, everywhere the time was determined by the Sun. There was no need for time zones, as there was no high-speed transport. The unification was due to the development of railways in England, because due to time differences in each city it was very difficult to draw up a normal schedule. It was the railway companies who ensured that there was one GMT time zone throughout the country. And then gradually the system of time zones began to spread around the world.

 Random interesting fact from the Great Encyclopedia:

Where can you see and taste natural watermelon snow?

In some high mountain areas, such as California's Sierra Nevada, you can see watermelon snow in summer. It is pink in color and has the smell and taste of watermelon. This phenomenon is due to the presence of Chlamydomonas nivalis algae in the snow, which contain the red pigment astaxanthin. These algae also serve as food for some organisms, including ice worms. They can only live in glaciers at low temperatures, and when heated to at least 5 ° C, they decay and die.

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.

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. ... >>

Xbox to PC wireless connection 27.10.2015

Wired connection of Xbox controllers to a PC is far from the most convenient solution. Xbox Wireless adapters will soon appear in stores, which will save you from wires, allowing you to connect gamepads to PCs and laptops "over the air."

The Xbox Wireless USB adapter released by Microsoft allows you to "over the air" connect console gamepads to home computers or laptops based on Windows 10. At the same time, the manufacturer noted that only Xbox One gamepads can pair with a USB adapter. Manipulators from the Xbox 360, unfortunately, will not work.

Xbox Wireless connects to USB 2.0 or 3.0 connectors. At the same time, the gamepad paired with a PC via an adapter performs all the same functions as when connected to a set-top box. Sales of the new gadget will begin on December 20 in the official Xbox Store, and it will cost about 25 USD.
