Why are snowflakes hexagonal?

The snowflake is one of the most beautiful creations of nature. We would have to work hard to create a shape comparable in beauty to the shape of a snowflake. When it snows, millions of snowflakes fall to the ground, and no two are alike.

Snow, as you already know, is just frozen water. Why then is snow white if it is frozen water? It must be colorless. Snow is white because the planes of the snowflake, which are ice crystals, reflect light, which is why snow appears white.

When water freezes, crystals form. This means that the molecules line up in a special order, forming a geometric shape, which we call a "crystal".

It so happened that the water molecule consists of three particles - two hydrogen atoms and one oxygen atom. Therefore, during crystallization, it can form a three- or hexagonal figure.

Water turning into snow is a form of water vapor in the atmosphere. When freezing, water crystals are so small that they are not visible. When snow forms, these crystals are moved up and down by air currents in the atmosphere.

During such movements, they are grouped around the smallest particles of dust or water droplets. Such a group of crystals becomes more and more, several hundred such crystals can gather around one such nucleus.

This group becomes large, heavy and falls to the ground. We call it "snowflake". Some snowflakes reach three centimeters in diameter. The size of snowflakes depends on temperature. The lower the temperature, the smaller the snowflakes.

Do you know that in some parts of the planet colored snow fell: blue, green, red and even black? This is due to the presence in the air where snowflakes form, a certain fungus or dust.

What French word, having found itself in Russian, was borrowed back by the French?

The word "hat" came into Russian from French through German or Polish. Later, a reverse borrowing took place, and now the French, in addition to the word "chapeau", in the meaning of any headdress, have a tracery "chapka", referring only to a Russian-style fur hat with earflaps.

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. ... >>

graphene lamps 02.04.2015

Lighting lamps made using graphene will soon go on sale in the UK. According to the developers, this is the first commercial application of a product with graphene.

Graphene lamps are expected to be slightly cheaper than LED lamps, which cost up to £15 in the UK. The light bulb with graphene-coated LED filament was created by Graphene Lighting with financial support from Canadian investors. One of the leaders of the company is the Vice-Chancellor of the University of Manchester, Professor Colin Bailey. Scientists of this university, physicists of Russian origin Andrey Geim and Konstantin Novoselov discovered graphene in 2004. For this discovery in 2010, physicists were awarded the Nobel Prize in Physics, and in 2011 they were awarded a knighthood by the Queen of Great Britain.

On March 20, the National Graphene Institute at the University of Manchester was opened, for the creation of which the UK government allocated 38 million pounds.

Graphene is a modification of a carbon compound. Thanks to its use, it is expected that the new lamps will have a longer service life, as well as about 10% less energy consumption.

The scope of graphene, which is stronger than steel, can be very wide. More than 35 companies around the world are working with the University of Manchester on projects using graphene. Graphene is already used as a component in the production of tennis rackets and skis. In the future, with its help, it is planned to increase the strength of aircraft frames, as well as to launch the production of more durable and lighter cars.
