The meaning and symbol of the stars

The following is a picture of the history of human flight: ** 1. Ancient Flight Fantasy and Initial Trial Stage ** 1. ** The flying imagination of myths and legends ** - In ancient Egypt, there was a legend of the goddess Isis spreading her wings and soaring in the air. The goddess Isis was in charge of life, magic, marriage, and fertility. The image of her wings reflected the ancient Egyptians 'yearning for flight. - In ancient Greece, Daedalus and his son Icarus tried to escape the maze by sticking feathers together and sealing them with wax to make wings. This was the embodiment of the ancient European dream of flying. 2. ** The prototype of early man-made flying objects ** - The kite was probably the first form of man-made aircraft. It was said that it was invented by Mozi and improved by Lu Ban. The wooden kite in ancient China could be used for communication and detection during war. It could also be used as a weapon for war. - Sky lanterns were invented by Zhuge Liang. The principle was the same as hot air balloons. They used the buoyancy of hot air to lift the ball into the air. In ancient times, it was used for military purposes. In modern times, it was used for blessing. The Mongolians used dragon-shaped sky lanterns to transmit signals during the Battle of Lignitz. - There had been "flying men" who had tried to fly in the past, such as John Damian who broke his thigh when he jumped off Stirling Castle in 1507, and a flying man who had put on a special cloak and jumped from a high place and died on the spot. Although these attempts failed, they were the first step in human flight exploration. 3. ** Da Vinci's Flight Research ** - In 1505 - 06, Da Vinci dreamed of flying and published his discovery. His Principles of Bird Flight contained thousands of notes and hundreds of sketches on the principles of flight and aeromechanics, laying the early foundation for the development of aviation and man-made aircraft. He simulated flying birds to design mechanical aircraft (ornithopter), leaving behind many research manuscripts and sketches. He was an important figure in the transition from ancient fantasy to modern flight research in the history of aviation. ** II. Modern Flight Development Stage ** 1. ** Hot air balloon flight ** - In September 1783, a balloon designed by the French brothers Joseph Michels and Jacques Mongofier successfully flew with a duck, a sheep, and a rooster. - On November 21, 1783, they conducted the first manned flight experiment with a hot air balloon. The balloon took off from the Bois-de-Boulogne in the west of Paris and flew for 25 minutes. This event was 120 years before the Wright brothers 'plane. - Ten days later, competitors Jacques Alexandre Charles and Nicolas Louis Robert's hydrogen powered balloons flew 25 miles and stayed in the air for more than two hours. 2. ** The development of the theory of aero mechanics and the appearance of gliders ** - In 1809 - 1810, Sir George Kelly of the United Kingdom published "On Air Navigation", which determined the four forces of flight (gravity, lift, drag, and thrust), proposed the first concept of fixed-wing aircraft, and designed the first manned glider. - In the 19th century, Otto Lilienthal published Bird Flight as the Foundation of Aerospace, which analyzed the shape and structure of bird wings in detail and applied them to practical flight. He was the first person to fly a fixed-wing glider more than 2000 times. The glider was derived from the ornithopter. 3. ** Development of Power Aerospace ** - On September 24th, 1852, the French engineer Henri Gifard completed the first controllable flight in the air with the Giffard Dirigible airship. It traveled nearly 17 miles from Paris to ELancourt, proving that powered air travel was possible. - In 1876, the German engineer Nicholas Otto designed a lighter and more efficient gas-powered internal combustion engine, laying the foundation for the new era of aviation. ** III. The Beginning and Development Stages of Modern Flight ** 1. ** The invention of the airplane ** - On December 17, 1903, the Wright brothers took off from Kitty Hawk, North Caroline, for the first controlled, continuous flight. Their wooden gasoline-powered propeller biplane, the Wright Flyer, marked a major breakthrough in the history of human aviation. 2. ** The appearance of helicopters ** - In November 1907, French engineer Paul Conu first tested a rotary-wing aircraft. It was lifted off the ground for about 1.5 meters and 20 seconds, becoming the first person to ride a rotary-wing vertical lift. This was the predecessor of today's helicopter. Italian engineer Enrico Forlanini first introduced the first rotary-wing aircraft in 1877, and American designer Igor Sikowski introduced a more standardized version in 1939. ** IV. The development of modern aviation technology and the application stage of bionics ** 1. ** Modern aircraft and bionics ** - The wings of modern aircraft were designed to mimic the wings of birds to increase lift and reduce drag. The navigation system mimicked the navigation ability of birds and used the Earth's magnetic field and the position of the sun to determine direction. 2. ** Drones and insects ** - In recent years, drone technology had developed rapidly. Some small drones imitated the flight mode of insects, which had better maneuverability and concealment. They played an important role in military reconnaissance, environmental monitoring, and other fields. The novel "Hundred Years of Spaceship" is equally exciting.

The yellowing of the leaves in the summer may be caused by a variety of reasons. The following are the corresponding solutions: 1. [Muffled Roots]: If a small number of leaves at the bottom turn yellow and fall off, it is normal metabolism, but a large number of leaves turning yellow and falling off may be stuffy roots. If the bottom of the flower pot did not have good ventilation and water penetration, it would cause damage to the roots and cause the leaves to turn yellow. The solution depends on the actual situation. If the root blockage is very serious, change the pot and soil, replace the higher deep pot, and use a shallow pot or small pot with good ventilation. The soil can be humus soil, slag ash, and base fertilizer (pine needles can be added) to ensure that it is loose and airy. If it is not too serious, there is no need to change the pot and soil. Find a chopstick or a thin wooden stick to poke the drain hole at the bottom of the flower pot to make the bottom more airy. Put it in a well-vented place and control watering. 2. ** Fat damage **: Summer is the blooming period of the boughs. If the fertilizer cannot keep up, it will affect the flowering. However, it is easy to cause fertilizer damage under high temperature. It may also be due to improper fertilizer use. If long-term use of potassium dibasic phosphorus, it will lead to a lack of nitrogen, which will cause the leaves to turn yellow. It was recommended to use fertilizers with high phosphorus content and no lack of other elements, such as Flower Duo Duo No. 2. If there is already a fertilizer hazard, the fertilizer strategy needs to be adjusted. 3. ** Large number of roots sprouting **: It is normal for the leaves to turn yellow when the roots sprout in large numbers. There is no need for special treatment at this time. After the roots develop, the leaves will naturally turn green. 4. [Iron deficiency: Yellow leaves and green veins. This is a typical symptom of iron deficiency. You can supplement it with iron or chelated iron.] 5. ** Watering problem **: The triangle plum is suitable for growing in slightly moist soil. Overwatering or too little watering will cause the leaves to turn yellow and fall off. In summer, it was best to water in the evening and avoid watering at noon. 6. ** Not enough light **: As a sun plant, the triangle plum needs sufficient sunlight to synthesize the nutrients needed for growth. If there is insufficient light, it is easy to cause the leaves to turn yellow. It is necessary to ensure sufficient light. "Fairy Dream of Tang Shi: Fate of Peony" is equally wonderful.
