1. When did the earliest models of air conditioners appear? Icon Ancient Egypt Icon Ancient Roman The correct answer is answer A: According to research by archaeologists and historians, the most primitive model of air conditioners appeared from ancient Egypt. To cool the indoor air and avoid the hot and dry desert climate, the ancient Egyptians hung bundles of water-soaked reeds in the windows. When the wind blows through the window, it will bring water vapor into the house. Another way of cooling the ancient Romans was that they surrounded the walls of the house with plumbing, when the water circulated, it would cool the house. Water cooling was also adopted by the medieval Persians. Their system includes wind towers and water tanks that help cool the indoor air. 2. Who came up with the first idea for an air-cooling system? Icon Michael Faraday Icon John Gorrie Icon Benjamin Franklin The correct answer is answer B: Scottish physician John Gorrie (1803-1855) Scottish physician John Gorrie (1803-1855), who gave the first idea of ​​the air-cooling system. Although the model and ideas above were never realized, in 1851, Gorrie was still awarded a patent for a machine that made ice. 3. Who invented the model of air cooling by adding salt to water as it evaporates? Icon Cornelis Drebble Icon Michael Faraday Icon Benjamin Franklin The correct answer is answer A: Beginning with the inventor Cornelis Drebble (1572-1633), he invented a model for cooling the air by adding salt to water as it evaporates. They were introduced to the then king of England, James I, but were not taken seriously. In 1758, the governor of Pennsylvania, Benjamin Franklin (1785-1788) and Professor of Chemistry John Hadley (1731-1764) at Cambridge University experimented and discovered the principle of reducing heat from evaporation. This was an important invention that laid the foundation for later air conditioners. Both Franklin and Hadley realized that the evaporation of a liquid such as alcohol or ether could lower the temperature of an object below the freezing point of water. Both men successfully experimented with evaporation to reduce the temperature of a mercury thermometer tube from 18 degrees Celsius to minus 14 degrees Celsius. By 1820, the British chemist Michael Faraday (1791-1867) made it. successfully experimented with compression and liquefaction of ammonia gas. During his experiments, he realized that evaporating liquid ammonia could cool the surrounding air, and this was one of the premise for later air conditioners. 4. Who first invented the modern air conditioner? Icon Willis Carrier Icon John Gorrie Icon Benjamin Franklin The correct answer is answer A: In 1902, Willis Carrier (1875-1950) invented a model of the air conditioner while working for the Buffalo Forge mechanical company. Willis Carrier was born in New England state (USA), from a young age, she was smart and bright. After graduating from Cornell University, Mr. Carrier worked in a heat-resistant suit. His research saves the company $40,000 per year. With this invention, Carrier is known as the father of the modern air conditioner model that we are using. However, Carrier’s air conditioning system is very large, noisy, extremely expensive and very dangerous because it uses the toxic chemical ammonia to cool the air. In 1911, Carrier continued to introduce “refrigerant formulations with reasonable humidity ratio”, this method of refrigeration is still used in some areas of the refrigeration industry. 5. Where was the Willis Carrier air conditioning system first used? Icon A movie theater Icon A printing factory Icon On the bus The correct answer is B: Willis Carrier’s air conditioning system is used in a printing factory. This system helps control the temperature and also keeps the humidity in the plant. Carrier’s principle of humidifying the air is quite simple, instead of pushing air through the heating tube, the air flowing through the tube is cooled by liquefied ammonia. 6. In what year was the Carrier-built air conditioning system first installed in a home in Minneapolis? Icon 1913 Icon 1914 Icon 1915 The correct answer is B: In 1914, a Carrier-built air conditioning system was installed for the first time in a house in Minneapolis. This machine is 2.1 meters high, 1.8 meters wide and nearly 7 meters long. But this machine has never been used because no one lives in the house. However, homeowners still have to spend more than 60,000 USD per year to maintain the entire house. 7. When was the first movie theater in the US equipped with air conditioning? Icon 1917 Icon 1918 Icon 1919 The correct answer is answer A: The household air conditioner has a height of 2.1 meters, a width of 1.8 meters and a length of nearly 7 meters. However, it has never been used because no one lives in the house but, the owner is a famous gambler who is rich and spends more than $60,000 annually on maintenance. From 1917 to 1930, the cinema was a place for people to enjoy the air cooled by air conditioning. The first movie theater in the US to be equipped with air conditioning was the New Empire Theater in Montgomery, Alabama in 1917. In that year, the Central Park Theater in Chicago also installed an air-conditioning system, which was enthusiastically received by customers. . Especially on summer days, the air conditioner is even more effective. In 1922, Carrier continued to make two breakthroughs in air conditioning. The first is that he replaces the toxic condenser ammonia with another, safer compound, dielene (dichlorethylene). 8. In 1969, the cooling system was fitted in Neil Armstrong’s spacesuit when performing a Moon walk, is it true or false? Icon It’s correct Icon Wrong The correct answer is answer A: In 1969, a cooling system was fitted in the spacesuits of Neil Armstrong and Buzz Aldrin to combat the conditions in space. These two astronauts wore them while on the Moon walk. Result Please work harder! point

Archaeologists examine the mummy. Everyone thinks this is an “unprecedented” archaeological find, but the truth is just a sophisticated scam. Shocking discovery In October 2000, police in Karachi, Pakistan received a tip that a man named Ali Akbar was selling a mummy for 600 million rupees, or about $11 million. According to the source, it was not an ordinary mummy, but “Princess of Persia”. Immediately, the police raided Akbar’s house, searched and questioned the suspect. Akbar then took the police to the home of his accomplice, Wali Mohammad Reeki, in the desert region of Baluchistan province. Here, the mummy in question along with the coffin was found. Reeki admitted to buying the artifact from a man named Sharif Shah Bakhi. This person told him that the body was discovered after an earthquake near Quetta, on the border between Iran and Afghanistan. Two men are arrested for smuggling antiquities, but the mystery of the mummy has only just begun. If it is true “Princess of Persia”, this will be a very important discovery, because no mummies of the Persians (present-day Iran) have been found. The mummy was brought to the National Museum in Karachi for experts to analyze and many mysteries surrounding this ancient man were revealed. The body was mummified in the Egyptian style, with a mask and a golden crown, placed on a reed mat. But the most interesting find was a breastplate covering the mummy’s chest, on which the ancient Persian inscription, “I am the daughter of the great king Xerxes. Mazereka protects me. I am Rhodugune.” In addition, the gilded wooden coffin is also decorated with carved lines also in ancient Persian letters. It all seems to show that this is indeed the Princess of Persia. Pakistani archaeologist, Ahmad Hasan Dani, of Islamabad’s Quaid-e-Azam University, excitedly announced in a press conference that, from what was recorded, the mummy was indeed a Ba princess. Tu, lived around 600 BC. This event sparked a dispute between Iran and Pakistan over the ownership of this unprecedented archaeological find. The Iranian Cultural Heritage Organization declared the “princess” to be a member of the royal family of Persia and demanded that Pakistan return the mummy, and even the Taliban movement in Afghanistan claimed it was their own artifact. Unexpected truth Mummy “Princess of Persia” in coffin. The fierce arguments between the parties have become a political problem, easily leading to conflicts. Meanwhile, some other archaeologists have raised doubts that this is the “Princess of Persia”, even a mummy. An independent examination was conducted and the archaeologists went from surprise to surprise. First of all, ancient linguists found that the writing on the mummy’s breast shield and the coffin was written by someone who was not fluent in the ancient Persian language, rife with grammatical errors, and even traces of pencil marks for inscriptions, which pencils were only invented in the 16th century. In addition, a piece of coffin was examined, it was only about 250 years old, and the carpet underneath the body was discovered to be only… 5 years old. Unusual signs were also found in the body of the “princess”, such as the delicate tendons and ligaments of the middle ear that were still intact, despite thousands of years and the mummification process. did not follow the strict methods of Egypt. For example, the heart was removed, which the Egyptians never did, as it was considered important to regenerate a person’s body when they went to the next world. Multiple CAT scans (computerized axial tomography), accelerated mass spectrometry dating, radiocarbon testing, and X-ray scans all proved this to be a hoax. delicate. In the end, scientists determined, there is no “Princess of Persia”, but this is the body of a 16-year-old girl, who may have died in 1996, not 600 BC. Not only that, there is evidence that the girl was murdered for this fraudulent purpose. Experts also discovered that the “mummy” had died from trauma caused by the force of the impact, which broke her cervical and back vertebrae. Her organs were removed, her body cavity filled with table salt and baking soda, a fake embalming process. All of this was likely done within 24 hours of her death. From an antiquities smuggling case to a murder case. It is said that a group of fake antiquities traders brutally killed this poor girl, or at least stole her body shortly after her death, to be processed into a donkey mummy. sell for money. However, although the police questioned everyone involved in the sale of the mummy, as well as several other suspects, it led to nothing. In the end, not only was no one arrested in connection with this young woman’s death, but the victim was also not identified. She languished in museums for a while, before being buried in 2008 by the Pakistan-based charity Edhi Foundation. Although she was finally laid to rest, she remained anonymous, unclaimed, and the cause of death was not clear, forever referred to simply as “Princess of Persia”.

Khan’s farm is located in Malihabad, a mango paradise in northern India with more than 10,000 hectares. Amir Khusro, the Indian-Persian poet, has called mango, native to India and tropical, subtropical climate, as “the most beautiful fruit of Hindus”. The cultivation of mangoes in India began many centuries ago during the Mughal Empire. This country is also the largest mango producer in the world, with more than 1,000 varieties and accounting for more than 40% of production. Mr. Khan and the mango season were good last year. The story of “mango trees 300 kinds of fruits” With the help of his son, Khan has grown mangos on 22 acres of farmland, a property cultivated by his grandfather since the 1900s. When Khan dropped out of high school and started his life, his family planted only a few local varieties, similar to nearby mango farms. Khan’s dream of grafting mangoes rekindled at the age of 15, when he saw a rose-hybrid tree in a friend’s garden. The flower tree had flowers of different colors that made him wonder if a single tree could produce such fruits. “Naturally I want to propagate the mango tree like what I saw on that rose bush,” he said. The 300-fruit mango tree is inspired by a hybrid rose bush. At the age of 17, Mr. Khan successfully grafted 7 varieties of mango into one tree. After the flood killed the tree, he determined to learn more about grafting in the family orchard. Over the years, Khan has been steadily improving his art of grafting. In 1987, he started grafting different varieties onto a 100-year-old mango tree. These mango varieties were collected by him from all over the country, including rare varieties. Mr. Khan said that the tree currently has more than 300 types of mangoes and he calls it Al Muquaraar. “Miracle Mango Tree” has a wide canopy, large enough to accommodate 15 people sitting under it. The branches are heavy with fruit with leaves of different colors such as gray green or olive green … The mango fruit on each branch also has its own shape: round or oval, some green, yellow, others have orange, pink and purple. The variety of each type is identified by a small label on the stalk: Dasheri mango from a nearby village, Himsagar from West Bengal, Langra from Bihar or prized Alphonso mango, sweet, saffron-colored mango in demand. high domestically and internationally. Mr. Khan’s three famous mango varieties are Tommy Atkins, Suvarnarekha, and Husn-e-Ara. “This miraculous mango tree is not just a tree, but an orchard, a universe,” said Khan. Free fruit donation, breed new breeds When asked how to protect trees from birds and insects, Mr. Khan said: “I don’t drive them away. The well-being of nature is for all to share.” During the harvest season, Khan and his son pack farm produce for sale and export. They give free fruit of “miracle tree” to visitors to the garden. “Like two kids from the same parents but different in looks and personality, mangoes sprouting from the same seed can also be completely different,” Khan said of each mango, as if it were kids. In addition to grafting, Mr. Khan also bred new varieties of mango, experimented with flavor and texture and gave them creative names. He named his new mango variety after Prime Minister Narendra Modi (Namo Aam) and Bollywood actor Aishwarya Rai. Khan said: “I created a mango after the famous cricketer Sachin Tendulkar. He called to thank him and expressed his happiness.” Most recently, he named two new mangoes “doctor aam” and “police aam” to thank the work of the rescue pioneers during the pandemic. Many famous people visited Mr. Khan’s farm. Mr. Khan won many awards, including the Padma Shri, one of India’s highest civilian awards, and recorded in the Limca record book. He visited Dubai and Iran to teach the art of grafting. In 1999, he created a mango tree with more than 54 varieties for the Mughal garden inside Rastrapathi Bhavan, the official residence of the President of India. “Mango grafting is just an art and has no commercial value,” said DK Sharma, vice president of the Mango Growers Association of India. Mr. Khan disagrees, saying that grafting is very common in commercial fruit and nut production. He considers it an art of practical value.
