Why are there no seasons on Mercury?

The axis of Mercury's own rotation is almost perpendicular to the plane of its orbit, and therefore there are no seasons on it in the sense that we put into this concept on Earth.

The sun's rays fall on the polar regions of the planet almost horizontally, and eternal winter reigns in them (there is no complete darkness at the poles only because the Sun is much larger than Mercury).

The results of research on Mercury suggest that there are glaciers at the poles of this planet closest to our hot star (the glacial layer can reach two meters and is covered with a layer of dust).

Random interesting fact from the Great Encyclopedia:

How did the double-headed eagle appear in the Russian coat of arms?

The double-headed eagle was the ancient coat of arms of the Byzantine Empire and was inherited by Russia after the marriage of Sophia Paleolog, the niece of the last Byzantine emperor, with the Grand Duke of Moscow Ivan III in 1472. The lost great empire seemed to have passed the baton to another Orthodox country, which was gaining strength and power, forming its own statehood and nation.

In 1497, the double-headed eagle first appeared as a state emblem on the double-sided wax state seal of Russia: on its front side is the coat of arms of the Moscow Principality - a horseman slaying a dragon (in 1730 officially received the name of St. George), and on the back - a double-headed eagle.

Over the past 500 years, the image of the eagle on the coat of arms of Russia has repeatedly changed. On seals, the double-headed eagle existed until 1918. The eagles were removed from the Kremlin towers in 1935. On November 30, 1993, by the Decree of the President of the Russian Federation, the two-headed sovereign eagle of Russia was again returned to the Russian coat of arms.

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

Gravitational lamps work without the mains 31.01.2019

The Gravity Lamp is the brainchild of London-based inventors Jim Reeves and Martin Riddiford. Its device uses a simple system of levers and weights to drive a miniature electrical generator. The new device is designed to help 1,3 billion people living in remote and poor regions without a developed electricity grid.

The peculiarity of the device lies in the fact that GravityLight does not require the usual sources of energy to operate. The light bulb burns thanks to a weight of 12 kg, which must be hung on a special hook. The load will gradually lower under its own weight, providing the lamp with energy for a little over 20 minutes. After that, you must repeat the operation so that the light comes on again. In fact, the device implements the same principle of operation as in a conventional watch with weights.

The developers of the device are confident that it will find wide application in poor African countries. The first prototype of the device was tested in 26 different countries last year and received high praise from the first users. According to the creators, the "gravitational" light bulb will not only bring light to homes, but will also allow many families to significantly save on the purchase of kerosene for lighting. The authors of the project pay special attention to Kenya: in this country they plan to establish an enterprise for the production of GravityLight lamps.
