The harmonica was invented in 1821 by the Berlin schoolboy Walter Buschmann. According to Pasteur, wine can rightly be regarded as the healthiest hygienic drink. The effect of cognac on the human body (nsk.su/ ~mera/organ .html) Vomiting can be stopped with heavily chilled champagne. The use of wine in certain diseases (omni.adt.ru/ vino/dejstvije .html) Obstetrics (from fr. accoucher - to help with childbirth; lat. obstetricia) - the doctrine of pregnancy, childbirth and the postpartum period. Gynecology (lat. gynaecologia; from the Greek. gyne - woman and logos - teaching) - in the broad sense of the word - the doctrine of a woman, in the narrow sense - the doctrine of women's diseases. Both of these areas are the oldest branches of medical knowledge and until the XNUMXth century. were not divided - the doctrine of women's diseases was an integral part of the doctrine of obstetrics. Medical site Badis. Obstetrics and Gynecology (badis.narod.ru/) At the end of the sittings in the English Parliament, the police shout Who goes home? (Who's going home?). This tradition began in the days when there was no central street lighting in London, and MPs went home in small groups, reducing the risk of being robbed on the dark streets of the city. Traditions of Parliament (uk.ru/ parliament_trad .shtml) The world's first monument to Russian vodka will be opened in the city of Uglich. The monument will be made by the world famous sculptor Ernst Neizvestny. He took the idea with humor and in his letter to the city authorities indicated that he was very flattered by the trust placed in such an important and traditionally delicate Russian subject for the soul and body of the state. SOBKOR - Information portal (sobkor.ru/) Sociopsychologists argue that the following law is one of the main tools of the modern art of negotiation, and there is practically no communication in the world in which it would not be applied in one way or another. Do you know that the steam engine, which made the industrial revolution in the XNUMXth century, was invented in Egypt in the XNUMXnd century BC by the Greek scientist Heron of Alexandria. According to legend, the new invention was used to pump water to the top of the tower of the famous Lighthouse of Alexandria, but then, by royal decree, its further operation was prohibited so as not to corrupt the slaves with laziness. How true the legend is is a moot point. For example, the famous American science fiction writer and popularizer Isaac Asimov argued that the steam engine designed by Heron was just a small toy that could not lift water even one foot, and not just on the lighthouse tower, which, due to its size, was classified as one of the seven wonders of the world. Knowledge is Power No4, 2001 Joseph Trumpeldor became the first Jew to receive an officer's rank in the tsarist army. It was a reward for the heroism he showed during the defense of Port Arthur in 1904. Then he lost his left arm and was taken prisoner. Knight of St. George from the Jewish Legion (sem40.ru/magendavid/georgiy_1.shtml) One of the first mentions of cabbage soup was a legend about the formidable Khan Batu, who did not destroy and burn a small Russian village only because its inhabitants brought him Russian cabbage soup as a ransom pot. Diplomat, No 2(82), 2001. In the first Russian Code of Laws, Russian Truth, many articles are devoted to the protection of beekeeping. According to Russian truth, for the plundering of the princely board (beehive) they took a fine of 3 hryvnias (the price of 1 horse or 9 sheep), and for the plundering of a peasant board - 2 hryvnias. For violation of the side boundary (honey collection area) a fine of 12 hryvnia is the same as for the unauthorized seizure of farmland land or the murder of a peasant. In nature, there are drones - albinos, with white eyes. beeland.boom.ru/byvaetvse/byvaet1.htm A theologian from Memphis (USA), Dr. Michael Ablunt, came to an amazing conclusion: most of the souls living in heaven belong to people who lived more than 40 years ago. The scientist made such a conclusion by collecting the testimonies of hundreds of people who survived clinical death and returned from there. anomalia.narod.ru/text000/2.htm In the language of the tailors of the Kaluga region, the phrase Klevi kapeni po lauda means Hit him on the head. Catherine II awarded Kulibin with a gold medal on the St. Andrew's ribbon. Catherine was depicted on the front side of the medal, and two figures on the other, of which one depicted Sciences, and the other Art. The Turkish Sultan Selim II was so addicted to drinking that even among the faithful Islamic chroniclers he earned the nickname Mast, which means a drunkard. Once, at a lecture by the German geologist Roemer, a student asked: Tell me, professor, where will I get if, for example, I drill a hole through the entire diameter of the Earth from this hall? To which the professor replied: ... To a psychiatric hospital. In the dialect of the Grebensky Cossacks, buza is a native beer made from millet, and they call freckles with the word hemp. The fourth Prime Minister of the State of Israel, Golda Meir, was born on May 3, 1898 in Kyiv, where her father, Moshe Yitzhak Mabovich, worked as a carpenter. She was named Golda (translated from the Yiddish language - golden) in honor of her great-grandmother, to whom she was strikingly similar. A WOMAN NAMED GOLDA (sem40.ru/ famous/polit26_1 .htm) Cellulite is a female-specific change in the adipose tissue that is part of the skin, which is manifested by the appearance of a finely bumpy skin surface. In simpler terms, cellulite manifests itself in the form of an orange peel. What is cellulite? (apelsinka.make-up.ru: 8101/about.phtml) Beethoven dedicated his famous work not to Elisa, but to Teresa. The manuscript of this piano elegy, written by the composer in 1808, has disappeared without a trace. However, Austrian musicologists were able to establish for sure that at that time Beethoven was caring for the daughter of a Viennese doctor Teresa Malfatti and it was to her that he dedicated his brilliant work. An error in the title of the work crept into the printing house. When typing the score, they probably could not make out the composer's disgusting handwriting, and the elegy To Elise was born. Knowledge is Power, Issue 5/01 (znanie-sila.ru/online/) November 5 Guy Fawkes' Day is one of the unique holidays in England, which arose from a completely non-holiday event. On November 5, 1605, a bunch of Catholics tried to blow up the Houses of Parliament along with the government, King James I, the queen and their son. UK.RU-All about Great Britain (uk.ru/ ) The classical Chinese Book of Changes (I-jing) was written about three thousand years ago. The book describes 64 hexagrams - symbols, each of which consists of six horizontal lines - yao. The line can be solid (corresponding to the masculine, or yang), or intermittent (corresponding to the feminine, or yin). Book of Changes (veritas.ph.ru/ gadanie/remena .html) We sincerely believe that the Zippo gas lighter is a truly American invention. And they are one hundred percent right, although it did not appear in America, but in Austria. Moreover, not in the middle of the last century, in the era of Mr. Colt, as it might seem, but only in 1932. The honor of creating the first Zippo belongs to the founder of the company, George Blaisdell. American legend (highstyle.ru/ articles/14-05-2001.1472 .html) The history of the Swiss army knife begins in 1884, when a certain Charles Esener, who returned home from a trip to southern Germany, founded his workshop near the town of Schwyz. In the past, he was a hatter, but when he saw German folding knives, he decided to make them himself. And in 1891 he opened a workshop for the production of army knives, which until that moment were imported to Switzerland from Germany. The official date of birth of the famous knife is July 12, 1897, when Ezener received a patent for the design of his product. The Steadfast Tin Soldier (highstyle.ru/ articles/16-05-2001.1489 .html) When peeling an apple, each of us must have tried to cut off as long a strip of peel as possible. American Kathy Wyfler took this entertainment seriously, chose a particularly large apple, armed herself with a sharp knife and cut a continuous tape 52 m 54 cm long. The result is listed in the Guinness Book of Records. As you know, the old unit of power horsepower (735.5 watts in conventional units) is actually much more than the amount that the average horse can develop for any long time. But when does a horse create such power? This question is answered by one of the authors of the American Scientist magazine: the power of one horsepower is developed by a horse weighing 750 kilograms, jumping over an obstacle 183 centimeters wide and XNUMX centimeters high. As you know, prime numbers are those that are divisible without remainder only by one and by itself, for example, 2, 3, 5, 7, 11, 13 The search for prime numbers began in the 1952rd century BC, when Euclid proved that their number must be infinite. But the number of prime numbers known to mathematicians grew slowly until computers appeared that could quickly check the divisibility of huge numbers. Thus, the largest prime number known in 157 contained 1985 digits, and in 65.050 - 1985. Now a group of American mathematicians, using a powerful computer, has surpassed the 65.087 record and obtained a prime number consisting of 350.000 digits. It took more than a year of work, it took XNUMX candidates for the honorary title to be tested, dividing each of these numbers by several billion known primes. The search for such numbers is interesting not only from a theoretical point of view. It allows you to improve calculation methods, test computers. In addition, the theory of prime numbers is used in cryptography - to develop ciphers. The Bible says that by order of King Solomon, a round copper vessel was made with a diameter of 10 cubits and a circumference of 30. Consequently, the number pi (the ratio of the circumference of a circle to its diameter), with the then measurement accuracy, was taken equal to three. Ancient Egyptian surveyors and architects believed that the circumference of a circle is 3,16 times greater than its diameter. The ancient Romans were wrong in the other direction: they considered the number pi equal to 3,12. However, for the technology of that time, such accuracy was quite sufficient. In the 35th century, the number pi was already calculated with an accuracy of up to 707 decimal places. For almost a hundred years, the record of accuracy remained with the English mathematician W. Shanks, who in twenty years manually deduced pi with XNUMX decimal places. When the first computers appeared, calculating more and more decimal places of pi became a kind of sport for programmers and operators. Shanks was found to have made a calculation error [at digit 536]. Already in 1962, the number pi with 100,000 digits was obtained, in 1973 the millionth milestone was reached. The latest advances in this area were made by the Japanese mathematicians Yoshiaki Tamura and Yasumasa Kanada. They calculated the number pi with 7,2 [2,097,152^2] decimal places in 21 hours of computer time. Then, using a faster computer, we got 2,9 [4,194,304^2] characters in 22 hours, and 6,8 [8,388,608^2] characters in 23 hours. What is the use of such studies, if even for the most accurate engineering calculations it is enough to have 5-6 decimal places? Firstly, this is a good test of the capabilities of modern computers. Secondly, mathematicians are interested in whether there is some order in the infinitely long tail of pi, for example, whether a natural sequence of numbers (123456...) appears somewhere in its distance. ENIAC - the first computer. The name is an acronym for Electronic Numeric Integrator And Computer. It was established in 1946. Currently housed in the Museum of the University of Pennsylvania. Contains 15,000 vacuum tubes, 10,000 capacitors and 70,000 resistors. It occupies an area of 140 sq.m. Computation speed - 5,000 operations per second. It weighs about 15 tons. Composer Richard Wagner was accompanied by the number 13 throughout his life. He was born in 1813. The sum of the digits of this year is thirteen. Wagner wrote 13 operas. September 13, 1837 Wagner became the conductor of the opera house in Riga. On April 13, 1844, he completed the opera Tannhäuser. On March 13, 1861, the premiere of this opera took place in Paris and was not a success. For 13 years the composer was in exile. On July 13, 1882, he completed the score of the mystery Parsifal. On September 13 of the same year, the composer went to Venice, where he died on February 13, 1883. Australia, which exports around $200 million worth of kangaroo meat annually, hopes to double its exports this year as demand grows in Europe, where mad cow disease and foot-and-mouth disease epidemics have caused meat shortages. There are over thirty synonyms for the word question in the Talmud. There is nothing similar in other languages. One word means an easy question, another - a difficult one, there is a special word for a question generated by a contradiction of two concepts, and its own - for a purely logical question. This list goes on. Always Learning - Central Jewish Resource (sem40.ru/ edu/question .shtml) Sorbonne - the name of the University of Paris - comes from the name of the monk Robert de Sorbon, confessor of Louis IX. On his initiative, in 1257-1258, a college for poor students was founded, which soon turned into the theological faculty of the university. Starting from the XNUMXth century, the name of the Sorbonne was transferred to the entire university. According to the Sunday Times, Bill Gates is no longer the richest man on the planet. Now you can find only $54 billion in his pocket, while about a year ago there was almost 2 times more. The first rich man is currently Sam Walton, owner of the Wal-Mart supermarket chain. He has $65 billion. Money, May 5, 2001 When Turgenev studied at St. Petersburg University, Gogol read lectures on the history of the Middle Ages to him. And when, after 2 years, Turgenev was already studying at the University of Berlin, Karl Marx studied at the same faculty at the same time. Tatars are the second largest nation in Russia, most of whom live outside of Tatarstan. Eremeev Airat, administrator of the Tatar store (kitap.ru) From 18 to 22% of twins are left-handed (in non-twins this percentage is 10). Identical twins have similar encephalograms. The science that studies twins is gemellology. Often, twins in childhood talk to each other in a language that is not understandable to others. This phenomenon is called cryptophasia. The first successful birth of eight twins was recorded in Houston, Texas on December 20, 1998. Parents - Nkem Chukwu (mother) and Ike Louis Udobi (father). Despite excellent medical care, the smallest of the children of Oder (the name means My life belongs to God) died on December 27, on the 7th day of life. All children were given the names of the Ibo tribe (Nigeria), where the parents come from. The total weight of children at birth was a little over 4,5 kg. According to various estimates, today in the world there are from 70 to 80 million pairs of twins. The main reason for the increase in the frequency of twin births continues to be the development of infertility treatments. Modern research shows that 80% of triplets were born as a result of the use of such methods. Even though identical twins have 100% similar genes, their fingerprints are still different. They may be similar, but never the same. This is why law enforcement still uses the method of identifying people, including identical twins, by their fingerprints. Doctors believe that 50 to 80% of multiple (twin) pregnancies end in the birth of one child, due to the loss of one embryo. There are also such figures: one out of 8 (according to other sources 12) pregnancies begin as multiples. Some women are not even aware that they could become mothers of twins, since the loss can occur just a few days after conception. If the sun rises with ears, that is, three rays, of which one is directed upward, the other - from one side horizontally, and the third from the other horizontally - this, according to the belief of the Tatars, portends cold. alabuga.ru/City/History/TatarMyths/kaum2 .htm Greeting at a meeting, the Romans instead of greeting asked: How are you sweating? domsovet.ru/index.php?goto=article&id=387 The name VOLVO, which in Latin means I roll. volvo.ru/history-1927-1929.xml If a real woman had the proportions of a Barbie doll, she could only walk on 4 limbs. gift.hotmail.ru/fact/fact0001.htm Serial production of toilet bowls was first undertaken at the beginning of the 20th century by the Spanish company Unity.
