Physicist Nikola Tesla is famous for his inventions of the laser, electric motor, ozone generator, bladeless turbine, alternating current, light and other discoveries. A genius who was in many ways ahead of his time, he was born in Austria-Hungary into a Serbian family on July 10, 1856. The scientist, who was engaged in scientific research throughout his long life, patented about 300 inventions that formed the basis of the second industrial revolution. Today we use most of his discoveries without even knowing who the author belongs to. On July 10, Nikola Tesla Day is celebrated in memory of the extraordinary man and great inventor. The ceremonial Nikola Tesla Day brings together representatives of the scientific community from many countries around the world, although it is not an official holiday. Several years ago, the Tesla Memorial Society in New York submitted an application to the UN to establish an International Day in honor of the scientist. However, the appeal remains unanswered, which does not prevent the inventor’s fans from celebrating his birthday every year. It is no coincidence that New York is home to the Tesla Memorial Society. The scientist moved from Europe to the USA in 1884 to work in the company of another famous inventor, Thomas Edison. The Big Apple was the site of the founding of the Tesla Electric Company, the invention of a new type of commutator, the arc lamp, and the two-phase synchronous machine. The scientist is credited with working closely with the US Navy on the eve of World War II - helping with the disappearance of the destroyer Eldridge by creating an "invisibility screen" for the Philadelphia Experiment. In New York in Manhattan, Nikola Tesla died in January 1943. The life of the inventor was full of mysticism and mysteries. Thus, Tesla claimed that while studying high-frequency currents, he had contact with spirits from the other world. His mysterious Electromechanical Oscillator during an experiment caused a disturbance in the earth's crust in New York in 1908. But Tesla destroyed his “earthquake machine” because... saw in its use a real danger to humanity. The scientist announced the invention of a superweapon that could destroy several armies at once. Some researchers attribute the fall of the Tunguska meteorite in Siberia to the results of experiments with it. Nikola Tesla Day is a celebration of scientific progress and the brotherhood of people around the world. The celebration is an excellent occasion to remember the scientist’s inventions, his views and way of life. It is known that Nikola Tesla was an “energetic vegetarian” - a proponent of people using the light of the sun to increase internal energy and vitality. In 1901, he suggested the possibility of communication between humanity and representatives of other planets. In 1914, he proposed a project according to which the Earth should become a huge lamp after running electric current through the upper layers of the atmosphere. The scientist had photographic memory and visual thinking, spoke 8 languages ​​fluently, and knew many books by heart. The contribution of this large-scale personality to the development of science and technology is still completely underestimated. The great inventor, thinker, visionary and visionary is remembered with joy and gratitude by inventors, scientists and ordinary people on Nikola Tesla Day.

Before the invention of the whistle, referees shouted, rang a bell, and waved handkerchiefs and flags to attract attention. With the invention on July 10, 1878 of a device for converting the energy of an air stream into acoustic vibrations, everything changed. Now, when the rules of the game were violated, the referee made a sharp and piercing sound.

The Battle of Poltava is one of the fateful battles for our country, which took place in 1709 in the fight against the Swedish army of conquerors. Thanks to Russia's victory in this armed conflict, a turning point came in the Northern War and the end of Sweden's superiority over European states. This day in modern Russia is celebrated as one of the days of military glory. The Swedish War began in 1700, the struggle was to ensure the Russian Empire's access to the Baltic Sea and the liberation of part of the original Russian territories from the yoke of the Kingdom of Sweden. The enemy had one big advantage - the strongest and most numerous army, which kept all of Europe in fear. The first years of the war, Russia suffered only defeats, essentially losing its navy. Since 1703, Peter I began to actively engage in military reform; by 1704, he managed to restore the Baltic Fleet and regain access to the Gulf of Finland. After the Russian emperor managed to recapture Levonia from the Swedes and build a fortified city (St. Petersburg) on ​​the territory close to Northern Europe, King Charles XII decided to devote all his efforts to conquering the central part of Russia, including Moscow. Swedish troops decided to penetrate into the Center of Rus' through Ukraine, not yet realizing that they had thereby made a huge mistake. In these parts they were caught in terrible weather conditions, an extremely cold winter for which no one was prepared. In the fight against the elements, the Swedish army was reduced by a third. On May 11, the enemy reached the walls of Poltava and began its siege. Thanks to well-coordinated work and competent leadership under the leadership of Colonel Kelsin and General Menshikov, the city fortress survived, continuing the fight for victory. By the end of May, the main power of the Russian Empire, led by Peter I, arrived to help the city. The troops were stationed on the opposite bank from the city, on the left side of the Vorskla River. By July 6, our army of over 42 thousand people moved to the opposite bank, concentrating near the village of Petrovka. The Russian military fought with all their might to prevent the enemy from reaching Moscow and won a great victory. The battle lasted almost three days, as a result, almost the entire enemy army was defeated, more than 9,000 Swedes died, 19 thousand were wounded and captured. The Battle of Poltava became a turning point in the Northern War, but Russia was able to win the final victory only in 1721. 1. Peter I after the Battle of Poltava received the rank of lieutenant general. And this is not a mere formality, he really fought heroically among ordinary warriors, a real “miracle” saved him, three bullets flew past him, one hit his hat, the second his saddle, and the third his pectoral cross, which he always wore near his chest. 2. The emperor had a cunning and inventive mind. He ordered the best military men to be dressed in rookie uniforms; this tactic bore fruit and was subsequently used in many battles. 3. In the last hours of the battle, there was a rumor that the Swedish king had fallen, but in fact he decided to show his acting talent, and under the guise of a dying man, he began shouting encouraging speeches, but it was too late, the “formidable and invincible” Swedish army had already capitulated. 4. In 1710, in honor of the victory, Peter I ordered the construction of the Church of St. Samsonia, because The victory in the great battle took place on the name day of this holy man. On the 25th anniversary of the victory, the famous statue “Samson Tearing the Lion’s Jaw” was erected in Peterhof. The animal is considered a symbol of Sweden, because... it is depicted on the coat of arms of this state. 5. The first modern celebration of this event took place in 1909; on the 200th anniversary of the victory, a medal “In Memory of the Battle of Poltava” was established, and a museum was opened at the site of the battle. Holidays of Military Glory should remind us of our ancestors, who were real heroes, sacrificed their lives to preserve the independence and unity of the state. On this day, we are obliged to remember and take as an example for ourselves how selflessly we need to love and defend our homeland, the exploits of our ancestors should not be forgotten.

Fermented soybeans are one of the traditional dishes of Asian countries. In the Land of the Rising Sun it is called natto. The dish has a salty taste and a specific pungent odor, similar to the aroma emitted by some blue cheeses. In feudal Japan, protein-rich natto was as popular as pasta meat. Fermented soybeans have a positive effect on the cardiovascular system and intestinal microflora, quickly fill you up and help control weight due to the low calorie content of the dish. In 1982, the Natto Producers Association established Natto Day to promote its sales. This holiday is celebrated on July 10th. The date of Natto Day is based on a play on words. The syllable “na” appears at the beginning of the name of the month “July” (七月), i.e. the seventh month of the year, and “to” is the number “10” (十日 - “tenth day”). Natto is one of the traditional national dishes of Japan, which due to its pungent smell and unusual taste is not very popular among foreigners. Therefore, Natto Day has not become a worldwide holiday, like, for example, International Sushi Day celebrated on June 18th. Natto is made from whole, washed and steamed beans, to which hay bacillus is added. Until 1974, the dish was prepared with a different crop - Bacillus natto. Bacillus subtilis is a probiotic, spore-forming bacterium that secretes digestive enzymes (lipase, amylase and protease) that kill pathogens in the body. After heat treatment, the beans are left to ferment for 24 hours, and then put in the refrigerator and after a week, when the natto has acquired a viscous consistency, served. The dish is usually eaten for breakfast, seasoned with mustard, raw egg, grated daikon or soy sauce. Natto is also added to soups, salads, sushi and ice cream. The dish prepared according to classic recipes is called “itohiki”. There is also dried, fried and salted natto fermented using the koji fungus. The Japanese associate the appearance of the dish in the Land of the Rising Sun with the name of the Chinese monk Gadzin, who lived in the 7th-8th centuries. BC. According to another legend, natto was the result of accidentally placing beans cooked for horses into rice straw bags, which were discovered by subordinate samurai Minamoto no Yoshiie, who lived in the 11th century. The soldiers liked the taste of fermented soybeans, and after a while 納豆 began to be cooked throughout Japan. Before the introduction of bread to the islanders' diet, natto was a staple dish served for breakfast. It was highly prized for its nutritional profile and ease of preparation. The Japanese eat 263 thousand tons of natto per year. It is more popular in the northeast of the country than in the southwest. Natto Day reminds residents of Japan about the recipes of national cuisine and encourages, despite the dominance of Western culture, to make a choice in favor of traditional dishes.

The holiday was established in order to draw public attention to the importance of bees, which make a huge contribution to maintaining balance in nature. These workers pollinate entomophilous plants, which supply approximately 1/3 of all food consumed by humans.

Samson Senognoy is celebrated among the people on July 10 (June 27 according to the old calendar style). The date received its name from a church date - the day of honoring St. Sampson the Host, who served as a model of selfless virtue for Christians. Sampson was born in Rome in the 5th century into a wealthy family who gave him a good medical education. He treated the sick without demanding payment for services, but having received an inheritance, he spent it on helping the poor and hungry. For his virtue, the Lord gave Sampson the gift of working miracles. The emperor, who was healed with his help, built a hospital and a hospice at Sampson’s request, where a church house was eventually built. The people called Saint Sampson more consonantly - Samson, and he was called Senognoy because of the frequent rains that spoiled the unharvested hay on this date. During this period, peasants cut grass, dried it, scattered it on the ground, and then collected it in stacks. If there was heavy rainfall when drying hay, it would rot and rot right on the ground. Such hay was unsuitable for feeding livestock in winter. On Samson Senognoi, the owners went to church and prayed to the saint to hold back the storm clouds so that the cut hay would not spoil. On this date, it was customary to honor distant travelers. If they walked along the street past the yard, then the owners invited them to visit, and, if necessary, arranged for them to spend the night. The travelers were offered to treat themselves to porridge with milk and butter, and then looked at the plate: if it was empty, then the grain harvest was expected to be generous, but the remains of the porridge promised a poor harvest and a difficult winter. Residents plowed the land freed from hay again. This gave the soil the opportunity to release steam and prepare for winter sowing. Then the horses and oxen that participated in the arable land were led to the temple and asked the clergy to read a prayer over them and sprinkle them with blessed water. This custom helped protect cattle from the pranks of evil spirits and the evil eye of unfriendly neighbors. Noticing thunderstorms on Samson Senognoi, residents were preparing for frequent precipitation throughout the summer. If the weather was sunny, dry days were foreshadowed before Indian Summer. Seeing drops of moisture on the horse sorrel, we prepared for precipitation in the following days. The closed bindweeds also promised imminent rain. Blackening grass after haymaking meant a generous harvest of wheat, greening meant an abundance of buckwheat.
