One kilometer of the subway (including the cost of stations) costs the city somewhere in the range of 30 million dollars.

The total circulation of books in Belarus is 64 million, that is, there are 6,4 books per inhabitant. In Russia this indicator is 3,9, in Ukraine it is about one. In the post-Soviet space, Belarus still publishes more books than its neighbors. However, in Poland there are 8 books per inhabitant, in Germany - 10.

According to the results of a nationwide sociological survey, almost half of Belarusian citizens (49,7%) would like to go abroad for permanent residence. Among the countries where Belarusians would like to move, Germany leads - 16,5%; followed by the USA - 9,4%; Russia - 4,9%; Poland - 4,6% and the Baltic States - 1,8%.

Musicians have larger and more receptive brains than people who don't play musical instruments. In professional musicians, the area of ​​the cerebral cortex responsible for hearing contains 130% more gray matter than in non-musicians. Amateur musicians have a smaller area of ​​the brain than professionals, but more than non-musicians. Such data were obtained by scientists from the University of the German city of Heidelberg, who, using scanning, compared the size and activity of the auditory cortex of the brain of 37 people. The activity of this area among regularly performing professional musicians was 102% higher than among those who do not play music, and among amateur musicians - by 37%. The auditory area mainly consists of gray matter and nerve cells (neurons) interconnected by long filamentous processes, called white matter. The scientists found striking differences between the three groups. In professional musicians, the largest amount of gray matter was found in an area called the Geschl gyrus. Thus, the structural features of the Geschl gyrus have a significant impact on musical abilities. NTVru

Cows have one remarkable property - the more they eat, the more milk they produce. However, the quality of the milk depends on what the cow eats. Good, tasty pastures are a headache for many farmers. In addition, Dr. Michael Friend from Charles Sturt University (Avrstaliya) found out the following interesting fact. Cows avoid eating grass around their own manure. The research was aimed at finding ways to increase the amount of milk produced by cows. Friend's experiment involved eight cows, which were monitored for six months using various sensors. When all the food on the clean pasture ran out, only one of the eight cows began to eat grass stained with manure, all the rest preferred to starve. Cow dung decomposes from a week to a month, depending on weather conditions and the activity of dung flies. In order to keep part of the pasture clean, the cows were put on ... diapers.

Lincoln Lab astronomers working on the Close Asteroid Research Project (LINEAR) discovered an asteroid that had passed Earth only 120 kilometers three days later, when the object was moving away from our planet. The asteroid that passed at such a close distance from Earth on June 14 was named 2002 MN. The object is 100 meters in diameter and is the sixth asteroid that has passed between the Earth and the Moon in the entire history of such events. Scientists missed the approaching object for two reasons. Firstly, the attention of astronomers is riveted to larger celestial bodies - from 1 km and more in diameter. And secondly, the southern hemisphere, from which the asteroid arrived, has not yet been covered by special search programs. This is not the first time this has happened. Asteroid 2002 EM7, 70 meters in diameter, passed 461 kilometers from Earth on March 8. The object approached the Earth from the side of the Sun, which made it impossible to register it. Scientists have calculated that if an asteroid entered the Earth's atmosphere, the explosion would be equivalent to an atomic bomb with a power of 4 megatons. According to NASA 2002 astronomers, EM7 will next appear near Earth in 2093.

LEDs were first created in 1962 by the General Electric Company. In 1968 they began to be included in some devices. But until 1985 they were used only for signal indicators of low intensity. Since then, it has been possible to increase their power, opening up new prospects for application. In 1993, the blue LED was created. And today, LEDs of all colors already exist, which made it possible to obtain pure white light for ordinary lighting.

According to renowned shark breeder George Burgess, the shark ranks last among the potential marine threats that await vacationers near the water. Moreover, every year 15 times fewer people die from sharks than from coconuts falling on their heads (as many as 150 people worldwide!).

Finally! The age-old problem of teapots has been solved. Even the most successful models have no, no, and a drop of tea leaves creeps from the spout. Scientists have long tried to come up with a teapot shape devoid of the defect of the teapot. This was done by a young designer from the UK, Damini Kumar, who presented her development called D-Pot at the recent Australian Innovation Festival. As expected, the whole secret of the new model lies in the spout, at the very tip of which you can see a centimeter-long groove ending in a bulge. This design narrows the space at the very outlet of the spout and speeds up the flow of tea. When the kettle returns to the upright position, the bulge serves as a barrier to the remaining liquid in the spout. The final model was the result of mathematical research and research in the field of engineering and fluid dynamics. It turned out that part of the problem was the surface tension, which tea has more than water. Therefore, if you test an ordinary kettle with water, it will turn out to be not so bad, but not suitable for brewing.

An international entomological expedition operating in Namibia announced that for the first time since 1915 a new order of insects had been discovered. These grasshopper-like insects live on the country's highest mountain, Brandberg. According to the Spanish newspaper El Pais, there are now 31 orders of insects, uniting about a million species. Now it is necessary to study 20 captured representatives of the new detachment at the Berlin Institute of Limnology. Max Planck. Scientists are primarily interested in the genetic and morphological features of newly discovered insects. It is already known that the location of the internal organs differs significantly from their location in grasshoppers and crickets. In addition, the hind legs of Namibians are weaker than those of grasshoppers, and the front legs have sharp protrusions.

Beer.

- The history of the WARSTEINER brand begins in 1753, when Konrad Kramer, the founder of the dynasty, received a license to brew. Most likely, he, a small farmer who brewed beer only for his family, could not even imagine that, after two and a half hundred years, his offspring would become a giant of the German brewing industry.

- The discovery in the 19th century of the Royal Spring - a spring water source optimally suited for making beer, became a new milestone in the history of the development of the WARSTEINER brand, WARSTENER beer became popular throughout Germany and a small factory in the center of Warstein could no longer satisfy the demand for WARSTEINER beer .

- The name WARSTEINER literally means brewed in Warstein. But according to German rules, beer has the right to be named after a city only when it is brewed in that city. And only in 1973, permission was received to build a huge brewery complex in a forest park located near the town of Warstein.

- Every 12th inhabitant of Germany, from the products of 1200 breweries and more than 4000 brands of beer, prefers one - WARSTEINER Premium Verum.

- WARSTEINER beer will never be produced in Russia, only in Warstein (Germany, North Rhine-Westphalia).

- Glasses cannot be wiped, but must be dried on a special grill. It is recommended to use electric or manual rinsing machines with pre- and post-rinsing. Before pouring beer into a glass, it must be rinsed with cold water. It is also better to pre-cool the glasses.

- Not so long ago, the press reported on a curious case with a student at Oxford University, Tom Bowder, who during the exam demanded, referring to an old law, a mug of beer. Since traditions are honored in England, and ancient laws are extremely reluctant to cancel, he received his coveted mug of beer, but was immediately fined for violating another equally ancient law, according to which students must come to the exam with swords.

- In one pub in the Japanese city of Matsushiro, there is an announcement that if an earthquake is more than three points (according to the Japanese scale), the client receives a free mug of beer.

Initially, the words BEER and ALE meant different drinks - hops were always added to BEER, which cannot be said about ALE, where hops were not added at all. Gradually, beer producers began to add hops to all varieties and the word BEER began to denote beer in general and included two large groups - ALE and LAGER.

- Pils is drunk from tulip-shaped glasses, Eli - from thin cylindrical glasses, Wheat beer - from very tall half-liter glasses shaped like a pipe. Strong beer is usually drunk in liter mugs.

You can describe the nature of this wonderful drink by translating the slogan of the manufacturer: Ein wirckliches Warsteiner, which literally means the only true Warsteiner, i.e. one of a kind, original and true to the best traditions of German brewing.

For those who choose prestige and quality, the German Warsteiner beer is ideal. All the nuances of its amazing fresh and soft taste can be appreciated by a woman; it is not for nothing that this beer is very popular among German women who are competent in the beer issue.

How do you, for example, such masterpieces from Warsteiner, or rather his lovers: A sparkling liner fell to the ground, only those who drank Warsteiner survived. Like pouring Warsteiner into a mug, it doesn’t pull on a girlfriend ....

The 1999 Ice Hockey World Championship in Norway was in danger of being moved to another country if the Norwegian authorities did not allow the German beer concern Warsteiner to advertise their products at the championship. The problem was that back in 1977, Norway passed a law against beer advertising, and in January 1998, the authorities dealt another blow to brewers by passing a new law that does not allow companies that produce lighter beers to advertise light beer. .

Meanwhile, the organizers of this year's World Championships in Norway are facing new challenges. Recall that until recently, due to a ban on advertising alcoholic beverages, the country of the fiords could lose the right to host the world hockey championship in favor of Sweden or Finland, but after long negotiations, the government agreed and introduced a temporary permit. This time, the German concern Warsteiner refused to sponsor the competition - according to an unofficial version, the reason for this was that the German team did not qualify for the 99 World Cup. business week

Hitler wanted to title his book Four and a Half Years of Struggle against Lies, Stupidity and Cowardice, but Max Amann, the director of the Nazi publishing house, cut the unattractive title. The book was called My Struggle (Mein Kampf).

The system used in ancient Rome when counting legionnaires: an area of ​​​​one hundred by one hundred meters - ten thousand people.

Polar explorers have a long tradition: to dilute pure alcohol to degrees of the parallel on which they drink. That is, at the Arctic Circle it will be 72, at the North Pole - 90, etc. Moscow, as you know, is located at 56 degrees north latitude. From here came Moscow vodka 56 degrees.

The giraffe is a dumb animal. He is unable to make any sounds. And further. Despite the fact that the giraffe has a very long neck, it has the same number of cervical vertebrae as the mouse - seven.

Psychologists have come to curious conclusions about the effect of the color of the package or label on the sale of products. So, red stimulates the appetite, so the labels on cans are often made red. Products with a white label are perceived as low-calorie. Green used to be considered unsuitable for food packaging, but now it is perceived as a symbol of environmental friendliness and health benefits. Orange color symbolizes inexpensive products, often sweets or drinks with the smell and taste of orange. Black with gold is a symbol of high quality and expensive products, for example, this combination is often used on the labels of expensive wines and cognacs. Science and Life, No10, 2000

The largest sapphire in the world was found in Thailand, it weighs almost seven kilograms.

Paul I had a son, Michael. It was known in advance that he would never have to become king, because there were older sons. But still, the father wanted the younger to live like a king. He ordered to set aside several hundred thousand rubles annually for the construction of the palace. Mikhailovsky Castle cost 17 million rubles (7 million rubles at the then exchange rate).

The cost of a gram of cocaine is a few cents (its production is no more difficult than the production of aspirin), and the selling price is 100-150 dollars. That is the price of a ban. Millions of narcodollars are withdrawn from legal circulation by the prohibitive efforts of the state, slowing down the economy. These are secondary losses. And the direct ones are millions of dollars spent by the state on an ineffective fight against illegal drugs.

The annual demand of the Russian market of illegal drugs is 500 tons.

By the age of sixteen, 70 - 85% of schoolchildren are introduced to taking legal drugs, and 15 - 30% have already tried illegal drugs. 28 minors are registered in drug dispensaries.

About four million citizens of the country have tried one or another prohibited substance, and the number of illegal drug addicts hovers around half a million.

The annual sales volume of illegal drugs in the world is at least 300 tons.

The average life expectancy of a heroin addict is 4,5 years after the first injection.

Today, when talking about whiskey, it is usually divided into Scotch and the rest - Irish, American, Canadian and even Japanese. Whiskey is a national pride of the Scots, in addition, the export of scotch brings more than 2 million pounds sterling to the British treasury annually. In English, there are even two ways of writing the word whiskey: whiskey - denoting Scotch whiskey, scotch and whiskey - the rest of the whiskey. Scotch whiskey is divided into single malt - single malt whiskey, the product of one distillery, the raw material for which is only barley malt and pure malt or blended - mixed (blended) whiskey, a mixture of malt whiskey prepared at different distilleries. Blending allows you to neutralize the sometimes too heavy or harsh tone of single malt components and get new interesting combinations of taste. WHISKY.RU - About whiskey

In 1917, 3 Roman Catholic churches, 2 Lutheran churches and 1 Anglican church, as well as 2 Muslim mosques operated in Moscow. In addition, there were 10 Jewish prayer houses - synagogues.

On July 11, 1804, the most famous duel in US history took place. It brought together longtime political opponents - US Vice President Aaron Burr (Aaron Burr) and George WASHINGTON's former secretary and first US Treasury Secretary Alexander Hamilton (better known for his portrait on a ten dollar bill). Hamilton was mortally wounded and died the next day. The reason for the duel was rather prosaic - during the presidential election, Hamilton allowed himself several personal and offensive attacks against Burr. Interestingly, the duel challenge took place at the end of June, but at the request of Hamilton, the duel was postponed and scheduled for July 22, 1804. Hamilton used these two weeks wisely and managed to set a certain Samuel Bradhurst against Burr so that a new duel was inevitable. They fought with swords, and although Bradhurst was significantly taller than Burr, to Hamilton's dismay, the duel ended in the bloodletting of Burr's rival.

For many years, the controversy around the Shroud of Turin has not died down. For believers all over the world, this is the greatest shrine, the burial shroud of Jesus Christ, for people who doubt, this is a creation full of mysteries. The first mention of the Shroud dates back to 1347, when Count Joffrey de Charny presented it for veneration in the church of the city of Lirea. It was said that this relic was brought to Liraea by a local crusader knight (according to another version, a soldier of fortune) from Constantinople. In the next few centuries, the Shroud survived numerous transfers from one city to another and the same numerous fires that literally haunted it. The name Turin comes from the city of Turin, where the Shroud has been kept since 1578 after numerous wanderings throughout Europe.

In 1956, the Decree of the Presidium of the Supreme Soviet of the USSR was issued, prohibiting the Gypsies living in the territory of the USSR from leading a nomadic lifestyle. As a result, all subsequent resettlement of gypsy families was carried out forcibly, and only on the outskirts of cities and in rural areas.

There are two Orthodox gypsy clans: Russian gypsies and Kotlyar gypsies. The name of the latter comes from the word boiler. After all, the original craft of kotlyars is tinning and working with metal. Today, these crafts practically do not exist. Gypsies are mainly engaged in buying and selling inexpensive things, selling or exchanging cars, rarely selling and stealing horses. Russian gypsies, on the other hand, live mainly by subsistence farming - they keep cows and pigs, cultivate the land. Gypsies still call their settlements in the old fashioned way - a camp. Boro is the eldest who is chosen by several families living together. Usually he is a wealthy respected person, able to solve both internal and external problems. Besides, the word Boro is a law. Anyone who disobeys him, by decision of the general meeting, can be expelled from the camp. As for religion, the gypsies, wandering around the country, accepted and professed the one that dominated this territory.

If a woman sleeps on the second floor of the house, and a man on the first floor, then the woman insults the man, since she is above him. Or, if a person dies in the house, then this house becomes unclean - the gypsies-kotlyars leave it and leave death. That is why they live in temporary houses, knocked together in haste.

Chinese proverb: First, good luck; secondly, fate; thirdly - feng shui; fourthly, virtues; fifth, education.

The Latin word religio means connection.

According to an ancient tradition, on New Year's Eve in Japan, the bells of Buddhist temples ring exactly 108 times. According to the Japanese, 6 vices are inherent in people: anger, stupidity, frivolity, gluttony, indecision and greed. And they appear in 18 different shades. Hence the number of bell strikes, each of which saves people from one shortcoming. Erudite, V.K. Ilyinov, Amber Tale, Kaliningrad

white roofs 10.09.2010

In 1820, Luke Howard, an English amateur meteorologist, first noted that it was always a little warmer in a big city than in the surrounding countryside (by the way, he also introduced the cloud classification that is still used today). City pavements and roofs bask in the sun more than natural greenery, and they heat up the air of the city.

An employee of the National Center for Atmospheric Research (USA) Keith Olson suggests painting the roofs of buildings white. Computer simulations showed that if all the roofs of city houses were painted with white, the difference between temperatures in the city and outside the city would be reduced by a third. The effect will be expressed mainly in summer, mainly for cities in the middle and southern latitudes.

In New York, such a measure would reduce the summer temperature by one degree Celsius. Unfortunately, it is hardly possible to paint the asphalt on the streets white.
