How many legs does a centipede have?

Not forty.

Despite the fact that centipedes have been studied for much longer than forty years, no one has yet been found who would have exactly forty legs.

Some have more, some have less. In 1999, an individual was discovered with almost a hundred legs. And more precisely, they counted exactly ninety-six, and this specimen is a real unique among centipedes, since it is the only one known to science that has an even number of pairs of legs: forty-eight.

All other millipedes have an odd number of pairs of legs, ranging from 15 to 191.

Who are the Vikings?

About 1200 years ago, a new tribe of sorts appeared in Scandinavia, consisting of people from the coastal regions of Norway, Sweden and Denmark. The very name "Vikings" probably comes from the word "viks", which in translation into Russian means "fjords" - narrow bays that cut the coast of Scandinavia.

The Vikings became great seafarers and adventurers. They were strong, tall warriors, usually fair-haired and blue-eyed. At a time when all the other peoples that inhabited Europe did not dare to sail on the ocean waves, the Vikings on their ships conducted maritime trade and made discoveries. They generally preferred a life full of wars and adventures to the warmth of the hearth.

In 793 a.d. e. Vikings first came to the coast of England. From that moment until the beginning of the XNUMXth century, they made regular raids on the coasts of western and eastern Europe. They robbed the inhabitants of the coast in England, Ireland, France, Spain. They even reached Algiers in northern Africa. The Vikings discovered the islands west of Greenland and part of the North American continent, which they called Vinland. There they created a colony that lasted three years. The Vikings had a unique culture. They built beautiful ships, made jewelry and weapons.

The Viking lands had large deposits of iron, and their craftsmen were skilled in working with metal. The Vikings have always been pagans. Their main gods were Odin and Thor. The Vikings believed that the gods lived in a place called Valhalla, and heroes who fell in battle were taken there after death. The Vikings had their own literature in the form of sagas - stories about the life of kings, nobility and ordinary people. The Vikings created their own system of laws based on justice and decency. Opinions are expressed that their traces can be found in the laws in force in many countries.

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 ... >>

Scientists have explained the whiteness of the snow 01.01.2019

French meteorologists answered questions about why the snow is white and the frozen water is clear.

In this regard, the experts recalled that the transformation of water or water suspension into snowflakes of various shapes is far from a simple process. In most cases, it begins with the fact that water is attracted to the smallest solid particles, which can be a hundredth of a millimeter in diameter. That is, initially it occurs in conditions of far from ideal air purity.

It is around the microparticle that the initial hexagonal prism is formed - with six lateral rectangular faces. Crystals continue to grow, but their further shape depends on the conditions in which they find themselves - on atmospheric pressure, the electric field of the cloud, wind, humidity and temperature. Moreover, the ambient temperature is the most important - it decides whether the upper or lower prism, or their side faces, will develop and change.

So, temperatures of minus 5 - 10 degrees Celsius lead to the formation of snowflakes in the form of needles or tiny thin columns. At temperatures of 10 - 12 degrees, snowflakes form in the form of plates or flakes. And only at minus 12 - 18 degrees are the most beautiful - in the form of "stars" with six rays. At the same time, each snowflake has its own characteristics and is unique, as it is formed from water crystals of various shapes and numbers. During their formation, snowflakes increase in size from half a millimeter to several millimeters.

The white color of snow is caused precisely by its structure. In ice, all crystals are strictly aligned and oriented. Light, therefore, passes through ice with only a slight change in direction. Snow, on the other hand, has ice crystals arranged randomly. As a result, light falling on one of them, in a refracted form, falls on the other, which again changes its direction. Moreover, snowflakes are even capable of decomposing white light into color spectral components - but as a result, all this gives exactly white color.
