Do I need to retrain the left-hander? Detailed answer Directory / Big encyclopedia. Questions for quiz and self-education Did you know? Do I need to retrain the left-hander? If you are left-handed or know any of them, you have noticed that left-handed people have to adjust to life in this world, since we live in a right-handed world. 96 percent of people are right-handed, and naturally everything from doorknobs, locks, screwdrivers, cars, musical instruments, and cars to little things like the buttons on our clothes are designed for right-handed people. However, most left-handed people seem to get on pretty well. And of course, there are examples of left-handers who have achieved a lot in life. For example, Leonardo da Vinci and Michelangelo, two of the world's greatest geniuses, were left-handed. While some parents get upset if their kids are left-handed, most medical authorities think it's wiser not to fix anything. The best development of the left hand is not a human defect, so the child should not be scolded or punished, and no effort should be made to try to turn him into a right-handed one. This is the opinion of the authorities. So what makes most people right-handed? For a long time, we were thought to be right-handed because of things like training, tradition, and as a result, most people are right-handed. Therefore, it was believed that something was wrong with the left-hander, because they could not do things the way others do. Today it is believed that most people are right-handed, because the brain of most people functions in a certain direction. One half of the brain dominates the other half. The left hemisphere of the brain controls the functions of the right side of the body, and the right hemisphere of the brain controls the functions of the left side of the body. And in most people, the left hemisphere of the brain dominates, so the right half of their body is more skilled and better developed. Our right hand works better than our left hand. Left-handers have the brain developed in the opposite direction. The right hemisphere of the brain is dominant, so the left half of the body works better. She works just as well, just as skillfully. It is pure coincidence that they are left-handed. And don't make a problem out of it! Author: Likum A. Random interesting fact from the Great Encyclopedia: How do bees communicate? When a worker bee finds a flower with nectar, how does she communicate it to others? How does she convey to them what kind of flower it is, how far away it is, and in what direction? The way in which bees communicate this information is one of the most amazing wonders of nature. To begin with, let's say that the language of bees is an instinct. They do not learn it, but simply, having reached a certain age, they automatically master it. Bee language is the language of smells and dances. When the bee discovers nectar or pollen, it returns home and starts dancing, describing regular circles one after another. The dance draws the attention of other bees and tells them where the nectar or pollen was found. Other bees by the smell of the returnee can find out what she has found. If the bee dances animatedly, it means that a large amount of food has been found, and many bees fly away to search. Thus, the bee can report several things. From the dance, you can determine whether nectar or pollen has been found. By the smell of the bee itself, you can tell which flower to look for. The slowness of the dance speaks to the quantities of food found. But all this applies only to flowers located within 100 meters of the hive. When the bee finds the desired plant farther away, when it returns home, it shows a different kind of dance. Instead of describing circles, she moves in a figure eight, connecting two loops with a straight line, while swinging her abdomen from side to side. In addition to the previous information, this dance tells the bees how far and in which direction to fly. The number of rotations per minute indicates the distance. The farther, the less eights are described. For example, 11 rotations per minute is equivalent to a distance of 2700 m. The line along which the bee walks between the two loops of the eight shows the exact direction. The line is determined by the position of the sun in the sky, so other bees can immediately determine the correct angle!
