Why is September the ninth of the year, although it literally means the seventh?

September is the ninth month, but its name is derived from the Latin word "septem", which means "seven". Similarly, the names of October, November and December come from the Latin numbers 8, 9 and 10. The fact is that in ancient Rome the year was counted from the first of March, and the names of the months corresponded to serial numbers. And under Julius Caesar, the beginning of the calendar was pushed back to January XNUMX, but they did not rename the months.

Why is Japan called the Land of the Rising Sun?

The name of the country - Japan - is conveyed by two hieroglyphs. The first of these signs means "sun", the second - "root, basis". Hence the allegorical name of Japan - the Land of the Rising Sun.

Japan is located on the islands, stretched out in an arc along the eastern coast of Asia. Once these islands were part of the mainland: the western coast of Japan is a continental shelf, similar in geological structure to the mainland itself. In the east, coastal shallows abruptly break off at deep, more than 7 thousand meters, oceanic depressions.

Japan lies on two archipelagos (groups of islands), located close to each other. The northern archipelago (or the Greater Japanese Islands) includes four islands - Hokkaido, Honshu, Kyushu and Shikoku. The southern Ryukyu archipelago consists of many small islands.

No map can show how indented the coasts of this country are. Rocks and mountains come close to the water, and the sea cuts deep into the land, forming lagoons, bays and bays. Thousands of small islands, rocky or forested, are scattered along the coasts of the larger islands.

Mountains cover three quarters of Japan. On the island of Honshu is the highest mountain in Japan - Mount Fuji (height 3776 meters), which the Japanese consider sacred. This is an active volcano in the shape of a regular cone with a deep crater. 10 months of the year its top is covered with snow.

Earthquakes are frequent in the mountains, and volcanic eruptions are not uncommon here, of which there are about 150 in Japan. After underwater earthquakes, huge waves arise - tsunamis that fall on the coast and destroy buildings on them. Especially destructive tsunamis occur near the island of Hokkaido and the northern coast of Honshu.

Typhoons often pass over the islands in July and August. The sky is covered with clouds, a gale-force wind is blowing, there are long torrential rains. During typhoons, huge waves can occur. Typhoons bring great trouble, cause floods, destroy crops. 10-15 typhoons pass through Japan every year.

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. ... >>

USB optical replacement coming soon 21.03.2012

Thunderbolt high-speed data transfer technology, which is predominantly present in Apple laptops, will be "upgraded" to fiber in 2012.

The replacement of copper strands with fiber optics in consumer Intel Thunderbolt data transmission technology will be implemented before the end of 2012, Intel spokesman Dave Salvator said. His words are reported by Macworld.

Thunderbolt technology was introduced just over a year ago as a faster alternative to USB 3.0 for connecting peripherals to a personal computer, including external hard drives and digital cameras. The maximum transfer rate in USB 3.0 is about 5 Gb / s, while in Thunderbolt, Intel promises to bring it up to 100 Gb / s. The technology was developed with Apple, and its computers were the first to feature it. The respective MacBook Pro notebook models were announced by the company in February 2011.

According to Apple, Thunderbolt allows high-performance peripherals, including RAID arrays, to directly access the PCI Express bus and can support FireWire and USB user devices, as well as Gigabit Ethernet connections via adapters. In addition, Thunderbolt supports DisplayPort for connecting high-definition displays and works with existing HDMI, DVI, and VGA display adapters. However, so far the technology uses cables with metal conductors and offers speeds not of hundreds of gigabits, but only 10 Gbps.

The partners did not dare to use fiber from the very beginning, as the cost of cables would have been much higher in this case. In addition to speed, optical technology will allow data to be transmitted over much longer distances - up to 100 m versus 6 m in the current implementation.

Freely available for incorporation into systems, cables, and devices, Thunderbolt technology is expected to become widespread and become the new standard for high-performance I/O.
When exactly the Thunderbolt fiber optic cables will go on sale and how much they will cost, Intel did not say.
