Which bridge is the longest?

This is the Akashi-Kaikyo Bridge, part of a system of bridges connecting Japan's main island of Honshu with the island of Shikoku. With a span of 1990 m, the structure is the longest bridge in the world. Pylons with a height of 282,8 m consist of two elegant steel towers connected to each other by steel structures.

Unlike European bridges, there are no aerodynamic "pockets". The bridge is designed for wind load: in case of strong wind, it can deviate from the average position by up to 27 m, which gives the bridge additional reliability.

The two longest bridges in Europe are in Scandinavia. Since 1995, a chain of bridges with a total length of 20 km has been built across the Great Belt, connecting the Danish island of Funen with Zealand. The heart of the entire gigantic structure is the East Bridge with a free span of 1624 m and a span height of 65 meters. It is not only the longest, but also the largest suspension bridge in the world. Both traffic lanes for the bridge start at 27m below the sea surface and then rise to 254m.

In June 2000, a tunnel-bridge structure 16,4 km long was put into operation for the passage of vehicles from the Swedish Öresund to Denmark. The complex was under construction for seven years; its main part is a two-story bridge 7,8 km long, suspended on reinforced steel cables at a height of 203,5 m.

Who was the first American president?

Peyton Randolph.

The first of fourteen (before Washington) Presidents of the Continental Congress, or "the United States assembled in a general Congress." The Continental Congress was a debating body formed by the thirteen colonies to draw up a list of grievances and grievances against the British Crown. At its second meeting, chaired by Randolph, Congress decided that Britain had effectively declared war on the colonies and, in retaliation, established the Continental Army with George Washington as commander-in-chief.

John Hancock, Randolph's successor, was the first to sign the Declaration of Independence from Great Britain, in which Congress asserted its right to govern the thirteen colonies.

After Peyton, thirteen other presidents presided over Congress until, on April 30, 1789, the victorious George Washington was sworn in as President of the independent United States of America.

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. ... >>

White sharks make animals stressed 11.12.2017

A scientific group from the University of Montana began to study how the neighborhood in the underwater world affects the psychological state of the inhabitants there. They were able to establish that white sharks are the main source of stress for many marine animals.

The study went on for several years. Experts observed how the life of fur seals from different colonies living in the waters of South Africa goes. It was possible to establish that the animals experience the greatest danger precisely when white sharks appear nearby. It was at these moments that the levels of the stress hormone cortisol in animals increased significantly.
The analyzes were carried out when the seals were in different conditions.

Stress, at its core, scientists explain, is a protective reaction of the body and often saves from serious consequences.

In the case of fur seals, it causes serious illness and can even lead to the death of an individual, as it has disastrous consequences for the heart.
