The most dead is not the Dead Sea, but the Lake of Death on the island of Sicily. There is no vegetation on its banks, and any creature that falls into it perishes. As it turned out, two sources of concentrated sulfuric acid spout from the bottom of the lake and poison the water.

The country of eternal thirst is called the Republic of Botswana in South Africa, whose territory is located in the large waterless Kalahari desert. The coat of arms of Botswana reads: Pula, meaning Let it rain! The greeting sounds exactly the same here, and the currency in the local language is called rain.

In Northern India there is a mountain gorge called the Valley of the Seven Deaths. It is said that not a single person has ever returned from there until recently. An expedition of Indian scientists found that deadly poisonous snakes are found there, and most plants emit potent poisonous substances. But the most dangerous is the local lake. It turns out that it belongs to carbonated, and from time to time carbon monoxide is released from its bowels, which fills the entire valley.

In the Arabian Peninsula there is a plant called LAUGHTER FLOWER. Its pea-sized seed can cause a person to have an unreasonable fit of laughter for 30-35 minutes, after which he falls asleep. The local population uses the grains of laughter to alleviate toothache.

In India, an interesting plant grows Kalir-Kanda, which is also called deceive the stomach. After eating 1-2 leaves of it, a person feels full for a whole week, despite the fact that they do not contain any nutrients.

In the rainforests of Indonesia, the KEPPEL tree grows, the fruits of which are so fragrant that the sweat of the person who tastes them takes on the smell of violets.

The fruits of the HANGA tree, which grows in the Philippines, contain almost ... pure oil.

BIRCH SCHMIDT (iron birch) grows in the Far East. It is one and a half times stronger than cast iron. If you shoot into its barrel, the bullet will fly off without even leaving a trace.

Near the Polish city of Wongravets, two rivers Velna and Nelba intersect strictly at right angles. And their waters, without mixing at all, after that flow further in their channels. The secret of this unique phenomenon lies in the differences in water temperatures in these rivers, different speeds and levels of currents. Experiments have been done here many times. Red paint was poured into Velna, and blue into Nelba. And at the intersection of the rivers, the colors did not mix: the red one ran into its own channel, and the blue one - over the red one - into its own.

wonder tree

Unlike most trees, the baobab does not die when the bark is stripped from it - it grows back. This tree does not die even when it falls to the ground. If even one of its roots retains contact with the soil, the baobab will continue to grow lying down. The Guinness Book of Records for 1991 talks about a baobab with a girth of 54,5 m. Huge hollows often form in the trunks of these green fat men.

In the Republic of Kenya, on the Nairobi-Mobasa highway, there is a baobab shelter - a hollow in it is equipped with doors and a window. In the Republic of Zimbabwe, in the hollow of one tree, they equipped ... a bus station, in the waiting room of which up to 40 people can fit. Near the town of Kasane in the Republic of Botswana, a baobab tree grows, the hollow of which was used as ... a prison. In Namibia, there is a baobab, in the hollow of which there is ... a bathhouse. There is even a bathtub.

Baobab - a universal tree:

- Its fruits, resembling large cucumbers, are distinguished by excellent taste and contain many vitamins, and in terms of their nutritional value they are equal to veal. They are quickly absorbed by the body and relieve fatigue. In addition to people, they are very fond of monkeys.

- The dried hard shell of the fruit is used instead of a glass. The smoke from burning the dry inside of the fruit repels mosquitoes and other pesky insects.

- The seed of the fruit is edible raw, and coffee is brewed from roasted and crushed.

- From the ashes of the burnt fruit, soap is made and, most importantly, oil, on which you can fry.

- With the powder prepared from the fruit of the baobab, the women of East Africa wash their heads, and with the red juice, which contains its roots, they paint their faces.

- From the leaves of the baobab, a delicious salad is prepared, soup is boiled, and young shoots are boiled like asparagus.

- Flower dust is used to make glue.

- From the ashes of the bark of the baobab, quite effective medicines are obtained against colds, fever, dysentery, cardiovascular diseases, asthma, toothache, insect bites.

Entertaining geography

Sight - reads like SITE and translated from English means VIEW. sight.ru

The distance on highways is considered from the post offices of cities and from the main post offices (post offices) in rural settlements. This has been done since the time when the payment for the transportation of mail was charged depending on the distance of the addressee from the mail.

But there is one exception to this rule: on roads leading from Moscow, the distance is indicated from Lenin's mausoleum.

On the railway lines of the country, kilometers are counted, as a rule, from Moscow railway stations, and on local railway lines - from terminal stations.

There is no more popular, more beloved hero than Ilya Muromets. However, few perceive this hero as a real historical person, a person who lived around the XNUMXth-XNUMXth centuries, canonized by the Orthodox Church as a saint and found eternal rest in the caves of the Kiev-Pechersk Lavra.

In 1988, the Interdepartmental Commission of the Ministry of Health of the Ukrainian SSR conducted an examination of the relics of St. Elijah of Muromets. The age was determined - 40-55 years, height - 178 cm.t (which was very impressive for Ancient Rus'), such defects of the spine were revealed that allow us to talk about the hero suffering paralysis of the limbs in his youth, but the strength of his spirit did not allow him to sit in a seat, as it is said in the epics. The disproportionate development of the musculature of the shoulder girdle and the incredibly large hands indicate that Ilya did not sit, but actively moved using his hands. It is established that the hero died a violent death. Two stab wounds were found on the body - one on the arm, the other, fatal, in the region of the heart.

In the books of the Lavra, another nickname of Ilya Muromets is also recorded - Ilya Chobitko, which, according to legend, was assigned to him because, being caught by enemies unarmed, the hero was able to fight them off with one of his boots (chobitko).

Ilya Muromets was officially canonized in 1643 among sixty-nine saints of the Kiev-Pechersk Lavra.

The large bell tower of the Kiev-Pechersk Lavra is tilted 62 cm in a northeasterly direction. Erected in 1731-1744. architect I.G. Shedel, it became for its time the most grandiose tower structure in Ukraine (height 96 m). However, unlike the famous Leaning Tower of Pisa, the Great Lavra Bell Tower does not fall; its slope does not increase. The inclination of the bell tower is connected, apparently, with the fact that it stands near the landslide slopes of the high right bank of the Dnieper.

The American Funeral Home offers alternative ways to bury the ashes. The remains of the cremated in a special capsule can be launched into space or to the moon using a satellite. Such a flight costs up to 12,5 thousand dollars. Another bureau offers to launch the ashes of the deceased into the sky along with fireworks - for 3 thousand dollars. The third option is to mix the remains with concrete and make an artificial reef out of them on the ocean floor (from 800 to 3 thousand dollars - depending on the number of dead in one reef).

English psychologists became interested in the question: which surgeons swear more during operations? The researchers tracked the progress of one hundred transactions, marking each word spoken in the hearts, and assigning each one to three points - from innocent damn it to obscene expressions. It turned out that orthopedic surgeons swear most often and most strongly, and otolaryngologists are the calmest of all. j-l Science and life, No 10, 2000

At the initiative of the American newspaper Washington Post, a special authoritative expert commission was created, which was faced with the task of highlighting all the very best that marked the end of the millennium. And here are the conclusions she came to.

Bamboo

Bamboo is not a tree, as many people think, but a grass that is a relative of wheat and rice.

No plant in the world is used as widely as bamboo. From this grass they build houses, bridges, make furniture, household utensils, water pipes, rafts, musical instruments, bones, canes, umbrellas, fans, toys and much more. It is better to eat without meat than to live without bamboo, say the Chinese.

Bamboo blooms once in a lifetime. But the flowering of bamboo is like a chain reaction. Its trunks are connected by underground rhizomes. One blooms, all will perish. They will die, even being in different countries, if they are taken from the same grove (!).

Bamboo grows very fast. At home - somewhere on the island of Java - it grows for forty meters in forty days. In terms of growth rate among trees, bamboo has no equal.

A banana is also not a tree, but a giant grass.

Something about the wolf

Although the wolf is a predator, it can eat carrots and watermelons with pleasure and in large quantities. So, in the southern steppe regions, wolves are frequenters of melons, where watermelon and melon grow. Moreover, the beast will not eat everything that falls under the arm (more precisely, under the paw). Sometimes he gnaws more than a dozen watermelons until he finds a ripe and tasty one. Wolves also eat pears and apples.

But still, wolves by nature are more meat-eaters. It is curious that where there is an opportunity to choose, preference will be given not to a sheep or a calf, but to a village dog. To your brother!

Observations of zoologists on Arctic wolves led to interesting results. It turns out that they do not pay attention to reindeer as long as they hope to swallow the mouse, which makes up 90% of their menu from spring to autumn.

Numerous legends about the attack of a wolf on a person most often do not correspond to reality. Wolves are not at all aggressive, they avoid a person and, when they meet him, turn into a stampede. Wolves (like many other animals) attack humans only when they are sick with rabies.

The howl of a wolf is in different cases either a call for mating (usually in February), or a designation of one's territory - information for other wolves.

Ayran (Ayran) translated from Turkic - a dairy product resembling kefir. It has been consumed from century to century as a soft drink in Kazakhstan, Central Asia, the Caucasus and Siberia. The peoples living in these regions have long been famous for their knowledge of many secrets and wisdom of maintaining vigor and health. So, going on campaigns, the nomads stocked up sun-dried cream, which, if necessary, was diluted with ordinary water to get ayran.

The ancient Egyptian calendar was the simplest of the solar calendars, which is why Copernicus used it for calculations. And how convenient: in each month there are three weeks of ten days, in each week there are two more half-weeks of 5 days each. Humanity so lacks the decimal system in the calendar! And every one and a half millennia (more precisely, 1460 years), the Twenty-First of March again fell on a pretty day, when day and night are of the same length, and then it begins to grow, grow, grow ... In general, the Spring Equinox or, as the Romans said, ekinox.

History of Orientation in Time: When to Rejoice in the Resurrection.

The first mechanical watch was invented in 996 by the famous philosopher and scientist Herbert Avrilaksky in Magdeburg.

In the 950th century, the French scholar Herbert of Avrilakus (1003–999) adopted the new number system from the Spanish Moors and, while teaching in churches and schools throughout Europe, introduced the new system to the West. In XNUMX, he was elected Pope Sylvester II, and this allowed him to further spread the new Indo-Arabic numerals. And although the unusual efficiency of the new number system made a real revolution in the performance of all counting operations and was quickly accepted by merchants, it did little to revive European mathematics.

Cigarette

Smoking causes 99 percent of throat cancer and 90 percent of lung cancer.

For various reasons, especially imitating adults, 5000 children take up smoking every day.

Around the world, 100 billion dollars a year is spent on cigarettes alone. For such a sum it is possible to solve the problems of health, education and upbringing of all children in the world.

In recent years, 5,6 million people have quit smoking in Canada, 10 million in England, and 40 million in the USA.

With one puff of cigarettes, 70 billion harmful substances enter the human body, 95 milligrams of carbon monoxide compounds. In addition, this person pollutes the environment.

Recently, the United States introduced a fine of $ 1000 for smoking in public places (indoors).

One of the three things that adversely affect the functioning of the human brain is smoking. The other two are hypertension and diabetes.

Children of smoking parents get as much nicotine in a week as their parents smoke (From a report by the US Department of Health).

The cigarette contains, in addition to nicotine, another 4000 types of toxic substances.

If for the normal functioning of the human body, far from cigarettes and alcohol, 75 mg of vitamins are needed, then smokers need 115 mg of them.

According to 1996 data, 215 billion dollars are spent on cigarette advertising every year.

Every year, 2,5 million people die due to smoking. This means that a cigarette kills one person every 13 seconds.

In different countries, a lot of children of smoking mothers due to lack of oxygen in the body are born mentally retarded.

There are 13 times more deaths due to smoking than from other drugs.

Infertility is 10 times more common in women who smoke.

Smoking is responsible for 80 percent of preterm births and miscarriages.

Among narcotic substances, cigarettes are more than others the cause of death and disease. If among non-smoking mothers, infertility occurs in 3,8 percent, then among smokers this figure reaches 41,8 percent.

For the money that people spend a year on cigarettes, you can buy the bare essentials for 15 years.

Cigarette smoke contains nicotine, hydrogen sulfide, carbon monoxide, carbonic acid, other acids, carcinogenic oils, and radioactive polonium.

Russian Tsar Mikhail Romanov sentenced smokers to be beaten with sticks. Alexei Romanov officially banned smoking in 1649.

The former Czechoslovakia ranked first in Europe for cigarette smoking. The cause of death of 40 thousand Czechs a year is a cigarette.

11 percent of sexual deviations are the result of smoking.

Each smoker smokes an average of 200000 cigarettes a year, or inhales 160 kg of burnt tobacco.

In 160 kg of tobacco there are 800 gr. nicotine. This amount of nicotine can kill 10000 people.

New LED lamps from LG 01.05.2018

LG Electronics has announced its intention to expand its line of LED lighting products with models that emit less blue light.

The South Korean company has already showcased 14 new commercial products under the LG Smart Lighting Safe Blue brand.

The blue spectrum of light penetrates deeper into the eyes, which affects not only fatigue, but also the general condition and well-being of users. That is why many manufacturers of smartphones and tablets equip their devices with a special mode that reduces the amount of blue light emitted, making the picture "softer" for the eyes.
