Why don't we speak the same language?

At the very beginning of history, humanity may have spoken the same language. But over time, this main language (or group of languages) has changed.

In the beginning, this main language was spoken by a small number of people. Gradually, the number of people increased, and there was a shortage of food. Therefore, they united in search of new habitats.

Arriving in new places and settling in, they spoke the language of their ancestors. Over time, the pronunciation has changed. Changed the name of some objects and the sound of words.

Old and unnecessary words fell out of use in the new place. New conditions required new words to describe them. The order of construction of the sentence has changed. And if people moved to places already inhabited by someone? The two languages merged, both languages changed.

In the beginning, when the speech of the new arrivals has undergone minor changes, this is called "dialect". Over time, with a change in words, sounds, grammar, we talk about the emergence of a new language.

Approximately in this way English, Norwegian, Swedish, Danish appeared from the Latin language. Dutch originated from the early Germanic language.

The original language, which gave rise to other languages, together with these languages forms a "family" of languages.

Random interesting fact from the Great Encyclopedia:

Malfunctions in what household system explain many phenomena from the category of a haunted house?

Many phenomena from the category of "haunted houses" are explained only by a poorly functioning heating system, which causes carbon monoxide poisoning in residents in low concentrations. The symptoms of such poisoning, in addition to headaches and fatigue, also include visual and auditory hallucinations.

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 ... >>

James Webb telescope launched into orbit 27.12.2021

NASA successfully launched the James Webb telescope. The telescope was jointly built by 17 countries, it took 25 years and 10 billion dollars.

Webb is much larger, more complex and more powerful than the Hubble Space Telescope, which has been studying the skies from Earth orbit for more than 30 years. Another key difference between Hubble and Webb is that the old telescope was designed to be serviced by astronauts on spacewalks, having been repaired and upgraded 5 times between 1993 and 2009. But the Webb will be too far away for people to reach it.

James Webb is the latest orbital infrared observatory to replace the Hubble telescope. The new telescope is XNUMX times more sensitive to wavelength than Hubble.

Scientists believe that the device will be able to expand mankind's understanding of the Universe, as it is able to reveal the history of the formation of the first stars and galaxies, as well as to study black holes, dark matter and galaxies far from the solar planet in more depth.

Telescope equipment is capable of collecting infrared light and examining it. In particular, the huge mirror consists of 18 hexagons. Its diameter is six and a half meters, and the combined area is 25 square meters.

At the same time, the device also has a thermal screen, the dimensions of which are 21,1 by 14,6 meters. The screen consists of layers that will protect the telescope from the sun's rays so that it does not overheat.

The telescope also has: a near-infrared camera that will form an image for the observatory; a device for working in the middle range of infrared radiation - will allow you to obtain data on distant objects (the formation of new stars or faintly visible comets); spectrograph of the near infrared range - will allow you to obtain data on the physical and chemical properties of objects; fine pointing sensors with a near-infrared imaging device and a slitless spectrograph - will allow you to obtain images in high quality, detect exoplanets (planets that are located outside the solar system) and determine their characteristics.

The launch of the telescope is scheduled for the summer of 2022.
