Focus Description:

Pull a chair to the middle of the stage and place a round stick across its back. Then twist it with your fingers. The stick will rotate around its axis without tipping over. When she has made enough turns, which will seem very surprising to the audience, remove her from the chair.

Focus Stick rotates on the back of a chair

Focus secret:

The stick did not tip over because it touched the chair with its center of gravity. The tip of a sharp needle protruded from it.

Focus Stick rotates on the back of a chair

When you put the stick in, you lightly press on it from above so that the needle enters the wooden back of the chair. It remains only to twist it and start to rotate it. Do not twist the stick too fast, otherwise it will fall and the focus will not work. The middle of the back of the chair must necessarily protrude above its edges.

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 ... >>

Adults evaluate children according to words 29.02.2016

Often in a conversation about children, you can hear that some boy or girl has a smart face or smart eyes (well, or not smart, but vice versa). On the other hand, it is just as common to hear that someone's son or daughter is developed beyond his years. But how do we assess how developed a child is? It seems self-evident that adults evaluate children by their appearance, by facial expressions: after all, children are not adults, and they cannot yet express their personality in words and deeds. However, in reality, appearance is not the main thing, and we believe more in what the child says than in how he looks.

Psychologists from Florida Atlantic University set up an experiment in which adults were shown several photographs of six-year-old children, boys and girls. Some photos were artificially "grown up" - so that the child looked not at 6, but at 8-10 years old, while other photos, on the contrary, underwent "rejuvenation" - the children looked 4-5 years old. The photographs were accompanied by children's thoughts-statements, which were supposed to help adults determine the psychological portrait of the child. For example, the phrase "the sun won't come out tomorrow because it's (at something) angry" obviously spoke of the immaturity, "childishness" of a child who still lives to a very large extent in his fantasies. That is, the descriptions indicated how boys and girls are oriented in the world, how intellectually developed, etc.

Combinations of words and photos were offered in a variety of ways: sometimes only a photo was shown, sometimes words were attached to the photo that "by age" did not match the photo (that is, in the photo the child, when compared with his own words, was younger or older), and sometimes a portrait photographic and verbal portrait coincided.

Adults, in the end, made their own psychological verdict: they had to say whether the child liked to lie, whether he was quick-witted, whether he was friendly, affable or not. Psychologists, in turn, concluded how an adult sees a child - as still small or as already large. As a result, it turned out that children were evaluated mainly by what and how they said.

For example, when a participant in the experiment (be it a man or a woman - gender did not play a role) described his impression of a child who "said" about the "angry sun", then he perceived him as a little one, no matter how old the boy was ( or a girl - here the floor also played almost no role) looked in the photo. Moreover, it was “very childish” thoughts that had the greatest power, that is, having heard some strange fantasy, an adult was more likely to underestimate the child’s age than, on the contrary, add years to him if he suddenly said something smart.

It must be emphasized that we are talking only about a certain age, from 4 to 10. At earlier times, we evaluate child development mostly in appearance - how plump the cheeks are, how round the eyes are, and so on. But then the children fully master speech, the school is already shining for them, the world is getting bigger for them, social interactions are becoming more complicated - and here, in order to understand how adequate the child is to the world, one cannot do without words.
