As a result of global warming, Western Europe may get colder. Warming occurs mainly in middle and high latitudes, as a result, the temperature difference between the poles and the equator is leveled, and because of this, the Gulf Stream, which heats Europe, may stop.

In the USA, a method has been developed for making a filament of an incandescent light bulb from crystalline tungsten of a special structure, which converts infrared light into shorter-wavelength visible light. As a result, the efficiency of the light bulb increases from 5 to 60 percent.

In the USA, solar panels have been developed in the form of the thinnest flexible film. You can cover threads with it, and then use this electric yarn to make a fabric that generates electricity when illuminated. True, the efficiency of new solar panels is still only two percent (conventional solar panels now reach 35 percent efficiency), but the inventors say that this is just the beginning. They hope that in a few years, a cell phone, walkman and other handheld electronics will be able to be powered by the wearer's suit.

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 ... >>

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. ... >>

virtual tourism 06.02.2005

The ETH Zurich (Switzerland) has created a computer model of the Swiss Alps, which is used by virtual tourists.

Real alpine landscapes are shown on the computer screen, and they can be changed: plant a grove or instantly cut it down to the roots, let a herd of cows, fill a ravine, pave a path, arrange a picnic area.

Each time, a “tourist” is allowed through the changed landscape, who then expresses his opinion about the beauties encountered and about the ease of overcoming the route. You can build a lift or funicular in a certain place and see if it will be popular with travelers.

The program is based on data from surveys of real tourists who traveled through the Alps. They were asked about which sections of the route and the beauty of mountain landscapes aroused the greatest admiration, why they chose this or that route, which places they would like to visit again, and what they did not like on the road.

The recommendations of the model are transferred to the area, which allows to increase the flow of tourists - a significant factor in the well-being of the country.
