Yuan Longping
Rice is the staple food of China people. But for a long time, the rice yield is not high and the population is large, so farmers can't meet the demand of "eating" by farming and planting rice all the year round. Low grain output is a big obstacle to China's economic development. Yuan Longping, an agricultural scientist, is determined to tackle key problems for the country and solve this problem.
Yuan Longping is an agricultural school teacher in a town in Hunan. Despite the poor working conditions, he devoted himself to scientific research. In addition to teaching every day, it is to cultivate high-yield varieties in experimental fields. In his experiment, he found that the natural hybrid rice had big ears and full grains, and high yield, but when it was planted again the next year, it degenerated and lost its advantage. He wants to carry out an experiment to cultivate hybrid rice seeds that can maintain high yield. For this ideal, Yuan Longping spent a lot of energy, sometimes observing in the experimental field, even ignoring his own home. After 10 years of efforts, it was finally cultivated successfully.
The yield per mu of this hybrid rice is over 65,438+0,000 kg. After the nationwide promotion, the rice output in China increased by 1 000 billion kilograms in a few years, which is really a leap! Yuan Longping won the first National Special Invention Award. The United States and other countries also introduced his achievements. Known as the "father of hybrid rice", he fought a turnaround to change the backward state of grain production in China.

The story of Edison
Edison is a world-famous inventor. When I was a child, because my family was poor, I only went to school for three months, and I started selling newspapers at the age of eleven or twelve. He loves science and often saves money to buy science books, newspapers and chemicals. The instruments he used in the experiment were bottles and cans picked out of the garbage.
When Edison 12 years old, he sold newspapers on the train. There is a special compartment on the train for passengers to smoke, and the conductor agrees that he will occupy a corner there. He moved chemicals and bottles and cans there. After selling newspapers, he did all kinds of interesting experiments.
Once, a bottle of white phosphorus was knocked down by a sudden vibration while the train was running. Phosphorus burns as soon as it comes into contact with air. Many people came to put out the fire with Edison. The conductor was so angry that he threw all Edison's experiments out and slapped him hard that he was deaf in one ear. Edison's determination to study science never wavered. He scrimped and saved, and started his chemical experiment again. On one occasion, sulfuric acid burned his clothes; On another occasion, nitric acid almost blinded his eyes. Undaunted by the danger, he still stubbornly did the experiment.
Edison did many experiments to find a filament with low price and long life. He often works in the laboratory for dozens of hours, so tired that he lies on the experimental platform and sleeps for a while. He made unremitting efforts and finally found a suitable filament and invented the electric light. Later, Edison invented movies and phonographs ... he had 65438+ inventions in his life.

Joule's story
Joule, a famous British scientist, loved physics very much since he was a child. He often does some experiments about electricity and heat by himself.
One holiday, Joule and his brother traveled to the suburbs. Joule, who is clever and studious, never forgets to do his physics experiments even when he is playing. He found a lame horse, led by his brother, and quietly hid behind him. He used a volt battery to electrify the horse, trying to see how the animals reacted after being stimulated by the current. As a result, the reaction he wanted to see appeared. The horse jumped wildly after being shocked and almost kicked its younger brother.
Although the danger has appeared, it has not affected the mood of little Joule who loves to do experiments. He and his brother rowed the boat to the lake surrounded by mountains. Joule wants to see how big the echo is here. They filled the musket with gunpowder and then pulled the trigger. Who knows "bang", a long flame spouted from the muzzle and burned Joule's eyebrows, almost scaring my brother into the lake.
At this time, the sky was covered with thick clouds, lightning and thunder. Joule, who just wanted to go ashore to take shelter from the rain, found that it took a long time to hear the thunder after every lightning. What happened? Joule didn't take shelter from the rain, dragging his brother up a hill and carefully recording the time of lightning and thunder with his pocket watch. After school started, Joule almost wanted to tell the teacher all the experiments he had done and ask for advice from the teacher. The teacher smiled at Joule, who was eager to learn and curious, and patiently explained to him: "The speed and harmony of light are different. The speed of light is fast and the speed of sound is slow, so people always want to see lightning before hearing thunder, but in fact lightning and thunder happen at the same time. "
Joule suddenly realized. Since then, he has been more fascinated by learning scientific knowledge. Through continuous study and careful observation and calculation, he finally discovered the mechanical equivalence of heat and the law of conservation of energy, and became an excellent scientist.

The story of Franklin
1one day in June, 752, in the suburb of Philadelphia, USA, it was covered with dark clouds and thunder and lightning. On a wide lawn, two people, an old man and a young man, are flying kites with great interest. Suddenly, a flash of lightning cut through the clouds and drew a "Z" in the sky. Then there was a loud thunder and the rain poured down.
The old man shouted, "William, stand in the straw house over there and tighten the kite string." At this time, lightning flashed one after another, and the thunder was louder and louder. Suddenly William shouted, "Dad, look!" " "The old man looked in the direction pointed by his son, only to see that the original bare and taut hemp rope suddenly burst into anger, and those tiny fibers stood up straight. He shouted happily, "It's coming!" While telling his son to be careful, he slowly approached the copper key attached to the hemp rope with his hand. Suddenly, as if he had been pushed, he fell to the ground and was numb. Without considering the pain, he got up from the ground and connected the Leyden bottle he had brought with him to the bronze key. There is electricity in this Leyden bottle, which releases electric sparks. It turns out that the sky electricity and the earth electricity are the same! He and his son took the Leyden bottle home like a treasure.
The people who seized Sky Power were Franklin and his son William. Franklin was not only a great scientist, but also an outstanding politician and diplomat. He was one of the founders of the Declaration of Independence and the first American ambassador abroad.
After the kite experiment, Franklin wrote a paper about the similarity between lightning and electricity, expounded the essence of lightning, and put forward the idea of making lightning rods to protect buildings from lightning. The lightning rod invented by Franklin was all the rage and spread to Britain, France, Germany, Europe and America.

Nobel's story
Nobel's father is a talented inventor who devoted himself to chemical research, especially explosives. Influenced by his father, Nobel showed a tenacious and brave character from an early age. He often goes to test explosives with his father. Years of studying explosives with his father also made his interest quickly turn to applied chemistry.
1in the summer of 862, he began to study nitroglycerin. This is a difficult journey full of danger and sacrifice. Death has always been with him. An explosion experiment exploded and the laboratory was blown up without a trace. All five assistants were killed, even his youngest brother. This amazing explosion gave Nobel's father a very heavy blow and died soon. His neighbors, out of fear, also sued Nobel to the government. Since then, the government has not allowed Nobel to conduct experiments in this city.
But Nobel is indomitable. He moved his laboratory to a boat in a suburban lake to continue his experiment. After long-term research, he finally found a substance that is very easy to cause explosion-mercury fulminate. He used mercury fulminate to make explosive detonator, which successfully solved the problem of explosive detonation. This is the invention of detonator. This is a major breakthrough on Nobel's scientific road.
Nobel made many inventions in his life and obtained 255 patents, including 129 kinds of explosives. As he lay dying, he was still obsessed with the research of new explosives.

The story of Einstein
Einstein was the greatest physicist in the 20th century. He likes to use his hands and brains since he was a child. Once in a craft class, he wanted to make a small wooden stool. As soon as the bell rang, the students scrambled to come up with their own works and gave them to this beautiful and strict female teacher. Einstein didn't take out his own work, and he was sweating with anxiety. The female teacher looked at the boy generously, believing that he could hand in a good work.
The next day, Einstein gave the female teacher a rough small bench, and one leg of the bench was nailed off. The expectant female teacher said to the class with great dissatisfaction, "Who of you has ever seen such bad shit?" The students snickered and shook their heads. The teacher took another look at Einstein and said angrily, "I don't think there will be a worse stool in the world." There was a burst of laughter in the classroom.
Einstein blushed. He walked up to the teacher and said affirmatively, "Yes, sir, there are worse stools." The classroom suddenly became quiet, and everyone looked at Einstein in doubt. He walked back to his seat, took out two rough wooden stools from under his desk, and said, "This is my first and second time to do it. The third wooden stool was just given to the teacher. Although it is not satisfactory, it is better than the first two. "
This time, everyone stopped laughing. The female teacher nodded to Einstein affectionately and thoughtfully, and the students also cast admiration and approval on him.
This short story shows us Einstein's resilience. When he was dissatisfied with his small bench, he went into production again. He made three small benches, and the last one was better than the first two. In the process of making a small bench, Einstein showed his attitude towards himself, that is, no matter what he does, he should try his best to do it well, release his energy completely, be dissatisfied with his achievements and give full play to his potential.

Delaisse invented the bicycle.
Nowadays, bicycles spread all over the world like a flood, entering thousands of households. But few people know that bicycles were invented by a German ranger named delaisse (1785- 185 1).
Delaisse used to be a forest ranger. He had to walk from one forest to another every day. Years of hard work on foot aroused his desire to invent a means of transportation. He thought: If people can sit on wheels, they will walk faster! In this way, delaisse began to design and manufacture bicycles. He made a unicycle with two wooden wheels, a seat and a handlebar, which is connected to the front wheel for control. People sit in cars and drive wooden wheels with their feet. In this way, the world's first bicycle came out.
18 17, delaisse rode his bike for the first time and was ridiculed all the way ... He was determined to answer this ridicule with facts. In a race, he rode for 4 hours, but the horse-drawn car took 15 hours. However, no manufacturer is willing to produce and sell this kind of bicycle.
1839, Macmillan, a native of Scotland, invented the pedal and put it on the front wheel of the bicycle, which greatly improved the bicycle technology. In the following decades, various bicycles emerged, such as windsurfing bicycles, water treadmills, ice bicycles and five-wheeled bicycles, and bicycles gradually became popular means of transportation. With the emergence of pneumatic tires and chains, the structure of bicycles is becoming more and more perfect.
Delaisse also invented the meat grinder and typewriter, which can reduce the labor intensity. At present, the trams that railway workers push by manpower on the tracks are also invented by delaisse, so they are called "delaisse".
