What are catacombs?

Catacombs were underground crypts located near Rome, where the first Christians were buried. When Emperor Nero began their persecution, Christians began to gather in the dungeons for religious rites. In addition, every citizen could escape raids in them. And later, Christians began to lay the main entrances and make secret ones, which were scattered for several miles in underground galleries.

They say that if the Roman catacombs are stretched in one line, then it will be longer than the entire coast of Italy. Under Emperor Constantine, the persecution of Christians ceased and the catacombs turned into a place of pilgrimage. When the Goths conquered and sacked Rome in 410, they walled up the entrances to the catacombs to protect against unexpected attacks by enemies.

In the XII century, the existence of dungeons was forgotten. They were walled up so carefully that they were accidentally discovered only in 1578. The catacombs were excavated, but only partially and to a depth of 3-4 meters. The width of the excavated provided a passage for the passage of two people. Steps sometimes led down to a depth of 12 meters. Some of the dungeons have 2 tiers or more. And one catacomb - St. Sebastian - even 4.

The lowest underground galleries diverge in different directions. Niches for burials were made in the walls of the galleries, which were usually walled up with stone slabs. Many of these stone partitions are now destroyed, and the current visitors to the ancient crypts have to walk between long rows of human bones.

What physical law helped to convict speculators of illegal insider trading?

In 2013, US authorities launched an investigation into certain players on the Chicago Stock Exchange. They were convicted of illegally using insider information when they started trading futures on completely different terms than before, just 2 milliseconds after an important announcement from the Federal Reserve. However, the simplest calculation showed that it would take 7 milliseconds for information to travel between Washington and Chicago, even at the speed of light.

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 ... >>

Homework and academic performance 13.05.2015

Is the proverb "Repetition is the mother of learning" true? A new study on this topic was conducted by Spanish sociologists from the University of Oviede under the leadership of Javier Suarez-Alvarez.

Scientists studied the performance of almost eight thousand high school students in the province of Asturias. The average age of students is 13,78 years, and 47,2% of them were girls. The researchers were interested in whether homework in subjects such as math and science affects performance.

The survey showed that half of the students do their homework every day, and a third almost every day. At the same time, in half of the cases it takes from one to two hours, in a quarter - from half an hour to an hour, and in a fifth - more than two hours. A third cope with it on their own, half sometimes need help.

These data were compared with the results of control works, which were evaluated in points, on average, about 500 points were obtained. As it turned out, those who do their homework every day and do it without the help of adults get fifty points more than others. An interesting result was obtained when comparing academic performance and the duration of homework: 20-minute work gave an estimate of 450-470 points, and 90-minute work - 510-530. Further sitting over the textbook is not necessary: ​​the grade drops.

From the study, the authors draw the following conclusion: “Our data is a clear signal for teachers: homework remains the most important tool for quality education, even in the current information society. "Homework should not repeat the lesson as it makes the task easier. On the contrary, it should be a little more difficult for the student to improve their skills, but not so difficult as to cause frustration."
