Random interesting fact from the Great Encyclopedia:

Where did the names of days of the week come from?

In ancient times, there was a time when the days of the week did not have their own names! The reason is very simple. Man has not yet come up with a week.

In that era, time was only divided into months, so there were too many days to assign a name to each of them. But with the construction of cities, people needed a separate day for trade, a market day. Sometimes such days were held every tenth day of the month, sometimes every seventh or every fifth. In Babylon it was every seventh day. On this day, no one worked, people met for trade and for religious ceremonies.

The Jews adopted this example, only setting aside every seventh day for religious purposes. This is how the week appeared - the days between the market, or market days. The Jews gave a name to each day, in other words, it was its serial number after Saturday - the day preceding the market day.

The Egyptians, who adopted the system of weeks, named the days of the week after the five planets, the Sun and the Moon. In ancient Rome, the Egyptian names of the days of the week were also used: the day of the Sun, Moon, Mars, Mercury, Jupiter, Venus, Saturn.

We have adopted a mixed form of the names of the days of the week: from Monday to Friday - serial numbers of days, Saturday and Sunday - these names are of religious origin.

By the way, when we say "day", we consider that this is the period of time between sunrise and sunset. In ancient Rome, the day lasted from midnight to midnight, and today many countries use this method.

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 ... >>

Bacteria follow commands 23.01.2017

Scientists were able to control the work of bacteria with the help of light. With the application of knowledge in the field of synthetic biology and genetic engineering, the process of controlling the vital activity of E. coli became possible.

According to scientists, bacteria, which will be programmed in the right way, can bring benefits to human health. Feeling some deviations from the norm, the bacteria can either compensate for the imbalance, or warn the person about the upcoming disease. In their work, scientists used a special method using redox molecules. With the help of redox processes, molecules were able to exchange electrons.

For experiments, scientists used bacteria such as Escherichia coli (E. coli). These bacteria are very sensitive to oxidative reactions. The scientific experiment consisted in the fact that the electrode was immersed in a solution with Escherichia coli bacteria.

When the electrode was positively charged, some of the redox molecules activated, stimulating the reaction of microbes to the reagent. With a negative charge of the electrode, the redox molecules ceased their action. The goal of turning bacteria on and off was achieved by scientists in this way.

An important result was achieved by minimal costs. In the future, these developments are planned to be officially recognized, over the course of 1-2 years some more scientific tests will be carried out to fix the achieved goal in general.
