Which railway line is the longest in the world?

The longest railway line on the planet is the Trans-Siberian Railway (Moscow - Vladivostok), the actual length of the main passenger passage of which is 9288,2 kilometers.

The Trans-Siberian Railway passes through the territory of two parts of the world: Europe (0-1777th kilometers) and Asia (1778-9289th kilometers). Europe accounts for 19,1 percent of the entire journey, Asia - 80,9 percent. There are 87 cities along the highway. 5 of them have a population of over 1 million people (Moscow, Perm, Yekaterinburg, Omsk, Novosibirsk). 14 cities are the centers of subjects of the Russian Federation.

On its way, the Trans-Siberian Railway crosses 28 rivers, of which 16 are large (Volga, Vyatka, Kama, Tobol, Irtysh, Ob, Tom, Chulym, Yenisei, Oka, Selenga, Zeya, Bureya, Amur, Khor, Ussuri). 207 kilometers of the road were laid along the shores of Lake Baikal.

 Random interesting fact from the Great Encyclopedia:

Who better plays the role of the night luminary: the Moon in relation to the Earth or the Earth in relation to the Moon?

The illumination provided by the full Moon at its zenith on the surface of the Earth is 0,25 lux, while the illumination provided by the Earth on the Moon at full moon is 15 lux.

Thus, the Earth copes with the role of the night luminary 60 times better than the Moon.

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

Improving the sensitivity of gravity wave sensors 12.03.2022

Physicists at the University of Western Australia have developed a new technology that aims to further increase the sensitivity of gravitational wave sensors, already the most accurate scientific instruments today. The introduction of new technology will raise the sensitivity to a level that previously could only be obtained by building new sensors, the dimensions of which exceed the existing ones.

The technology uses a "symbiosis" of quasiparticles, which are quanta of sound vibrations called phonons, and photons of light from a special laser. The resulting quasi-particles of a higher order of complexity make their own oscillations with a frequency of billions of times per second, all this happens without any energy loss and is used to amplify the signal from the gravitational wave sensors.

The main problem that did not allow to implement something similar earlier is that phonons, which are carriers of quantum information and act as signal amplifiers, are literally lost in a huge number of random phonons, called thermal noise background.

The solution in this case was a technology called White Light Signal Recycling (WLSR), and the key component was the so-called phononic crystal (PNC) resonator, made from a high purity quartz crystal. This resonator has a rather complex shape with alternating holes of different diameters and protrusions created in certain places. The view and structure of the PNC resonator is shown more clearly in the pictures presented here.

The use of a PNC resonator cooled to a temperature of 1 Kelvin and a fairly complex optical system, which includes lasers, mirrors, lenses and other components, made it possible to create a WLSR interferometer and, at the same time, a signal amplifier capable of operating in a wide frequency range, in which frequencies of signals of gravitational waves of various types enter. Only by using the new WLSR interferometer, the sensitivity of current sensors can be increased by at least 40 times.
