Do elephants remember everything?

For centuries, various legends have been circulating about animals, and often people believe in them. One such legend says that elephants never forget anything.

Elephants do have a good memory, probably stronger than other animals. There are many cases when elephants remembered people who harmed them, and took revenge on them even many years later. But still there is no doubt that elephants cannot remember everything.

Just think how difficult it is to tame and train a wild elephant. The trainer sometimes has to be cruel, hitting the animal and forcing the elephant to do what he does not want to do. But since the elephant "forgets nothing", he is not amenable to training, but will constantly attack his trainer.

What is tin-lead alloy?

First, an alloy is a metal that results from mixing several metals during smelting. The basis of the tin-lead alloy is tin. It is usually mixed with lead in the following proportions: 6 or 4 parts of tin to 1 part of lead. Such an alloy has been produced for thousands of years, although it is difficult to give a more precise date. It is said to have been known to the ancient Chinese, Egyptians and Greeks. The ancient Romans also made it.

Usually the mention of the tin-lead alloy is associated with England, and there is a reason for this. In Cornwall there were mines with deposits of high quality tin. England has been smelting it since ancient times, and tin from Cornwall has been used to make such alloys in other parts of Europe. Tin-lead alloy was used for three main purposes: for the manufacture of church utensils, for domestic use and for public use. Communion bowls made from a pewter-lead alloy have been used in church services in England since the Middle Ages. In England, this alloy began to be widely used for the manufacture of plates and cups.

But over time, the rich began to prefer silverware, and the middle classes used a tin-lead alloy instead of silver.

In France, this alloy has been used to make glasses and goblets, plates, salt shakers and pots since the XNUMXth century.

In Germany, the industrial production of tin-lead alloy arose in the XIV century, and almost at the same time it began to be smelted in Belgium, Holland, Switzerland, Russia and the Scandinavian countries.

In the United States during the early colonial period, it was used more for household purposes. Some items date back to the 1750th century, but the largest amount of alloy was produced between 1850 and 1000, when it was used to make any household utensils. Tin-lead alloy was smelted in China, Korea and Japan more than XNUMX years ago.

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 ... >>

Bat robot 02.03.2014

American engineers have analyzed the flight mechanics of bats for the first time and in the near future will use the collected data to create a robot that can fly in the air and maneuver in the same way as its living bat "ancestor", according to an article in the journal Physics of Fluids.

"Bats are generally very agile and nimble and have the ability to change flight paths very quickly, which helps them quickly maneuver and catch prey mid-flight. We were interested in how they do this," said Danesh Tafty of Virginia Tech in Blackburg (USA).

Tufty and his colleagues unraveled the mysteries of bat flight by studying the anatomy, mechanical properties, and wing movement of fruit bats, large bats from the Pteropodidae family. These bats, despite the rather large wingspan of 40 cm, have a relatively small mass - about 30 g.

Small mass and large wings can create serious problems with strong gusts of wind. The authors of the article found that bats cope with them by constantly changing the shape and size of the wing during up and down flapping.

For example, bats increase wing area by 30% during their downstroke to maximize "useful" air currents, and decrease it by a similar amount during their upstroke, minimizing downward pulling forces. Due to this, fruit bat wings generate 2-3 times more lift than glider wings of similar area.

“In the near future, we will break down these seemingly complex wing movements into simple elements, which is necessary to create a bat robot. In addition, we plan to study other bat movements, such as flying in a straight line and quick maneuvers. And the main question will be whether we can use this information to create an autonomous aircraft," Tufty concludes.
