⑴ Please ask for short stories about the inventions of ten scientists, preferably 50 words

1. Copier

At first, the paraffin paper invented by Edison was only widely used in On food and candy packaging materials, he later tried to carve the outline of characters on wax paper to form a paraffin engraving paper plate, put white paper under the paper plate, and then rolled the ink roller from the engraved paraffin paper. Something wonderful happened, clear writing appeared on the white paper.

After many improvements and experiments, in 1976, Edison began to produce the copier he invented. All of a sudden, agencies, schools, institutions, and groups all used this wax paper mimeograph machine. Due to the popularity of Edison's copiers, which became popular all over the world, Edison deeply realized that he should invent something that people generally and deeply need.

2. Synchronous transmitter

The early telegraph could only transmit one message at a time, and could not exchange signals at the same time. Since Edison itself was a telegraph Technicians began to improve the traditional transmitter and created a double transmitter. In 1974, they developed a quadruple transmitter, which is a synchronous transmitter. At a time when radio had not yet been developed, the synchronized transmitter was a major breakthrough.

3. Improved telephones

We all know that the modern telephone was invented by Bell. In fact, the fact that the telephone can receive and speak clearly is attributed to Edison time and time again. The experiment broke through the traditional stereotypes and created a toner microphone, which improved the sensitivity, volume, and receiving distance of the phone in one fell swoop. Otherwise, we would still often say: Hello! Hello! Can't hear you, can't you hear me? clear.

4. The Birth of the Gramophone

One night in December 1877, the staff of the Mengluoyuan Laboratory shivered slightly, not because of the cold, but because they heard that human beings The first recording in history: "Ma Li had a little sheep. Its fur was as white as snow. No matter where Ma Li went, the lamb was always by her side...

This great invention, No need for Mr. Little Jar to introduce it, everyone can understand how widely it is used. The French Revolution even awarded Edison the title of Sir for this reason! Later, Edison improved the phonograph many times until he changed the drum type to It was not just one or two years before the Bakelite turntable was developed, but decades of continuous improvement!

5. Newton

Newton alone in the orchard at home While walking and thinking about the problem, he accidentally bumped into an apple tree in the garden. At this time, an apple happened to hit Newton's head. Newton suddenly woke up from the problem and picked up the apple. At this time, he fell into another problem. : Why does the apple fall to the ground instead of floating in the sky? In the end, Newton proposed a universal law of the simplest phenomenon: universal gravity

Yes. Once, Socrates was walking on the street and someone hit him on the back with a stick. The pain made him unable to stand and he squatted down, but soon he stood up again as if nothing had happened. Seeing that he had no reaction, he curiously asked him: Why didn't you fight back when you were beaten? Socrates smiled and replied: When a wild donkey kicks you, will you kick it back?

< p> Cut a hole in the wall to steal the light

Kuang Heng, also known as Zhigui, studied hard but had no candles, so Kuang Heng cut a hole in the wall to attract the candlelight from his neighbor's house. , read by candlelight. There were many books in the house of a man who was ignorant of humanities in the same county. Kuang Heng was hired by his family to work without any reward. The owner asked Kuang Heng strangely, and Kuang Heng said, "I hope I can get all the books in my house." Read it through. "The owner was surprised and lent Kuang Heng the book. Later he became a university scholar.

⑶ A short story of a scientist's invention in 50 words

1. Edison

In When Edison was young, he often went to the mill of his neighbor Muir Winchester's house. One day, he saw Winchester experimenting with a flying device using a balloon. The experiment fascinated Edison. He thought that if a person's stomach was full of gas, he would surely rise to the sky.

A few days later, Edison mixed several chemical raw materials together and gave them to his father's helper. Michael Oates ate it, and Edison told Michael Oates that people would fly after eating this kind of thing. As a result, Oates almost fainted after eating the "flying agent" prepared by Edison.

Edison was affected by this. In spite of his father's whipping and the vigilance of children's parents, he advised his children not to play with Edison and stay away from him.

2. Fulton

Fulton had not read much since he was a child. His parents did not have the money to send him to school, and his subsequent achievements were all due to his own efforts. From an early age, Fulton loved to fantasize. For example, after helping the adults with farm work, he would often sit alone in the attic of the farmhouse. Sitting for hours in the small lattice window looking out over the fields and the blue sky

One day the weather was clear and the river was clear. The neighbor's uncle drove the boat to the upper reaches of the river to find work. They began to leisurely hold their poles and swim upstream.

When Little Fulton went to a place far away from his village, he felt particularly happy and could not help singing American rural folk songs. The "gurgling" sound of the river and the melodious and melodious singing of Little Fulton are intertwined, which is intoxicating. The morning sun rises higher and higher, and the sunlight shines on the water waves, like broken silver on the green ribbon.

Suddenly, the water flowed quickly and the boat was spinning in the river. Fulton and the neighbor uncle desperately tried to punt, their clothes were soaked with sweat, but the boat could only move with difficulty. Little Fulton thought to himself: It is too laborious to hold the pole. How great it would be if there was something that could make the boat move automatically!

He imagined his wings flying in the river, and he seemed to see an autonomous boat appearing in the river. His mind returned to reality, and he said to the neighbor's uncle: "Uncle, it's hard and slow to hold the pole. It would be great if there was something that could make the boat move automatically!"

Neighbor The uncle was holding the pole with all his strength. Hearing what Little Fulton said, he couldn't help but smile. He wiped the sweat from his face with the back of his hand and said with a smile: "If there is something that can make a boat move automatically, what is it?"

"Yes, what is this thing?" ?" Little Fulton's face turned red instantly. He pushed the pole hard, lowered his head, and fell into deep thought again.

Since then, "How to make the ship move automatically?" has become the central question that little Fulton thought hard about. As a result, when he grew up, he worked hard and finally became a famous scientist who built mankind's first steam engine ship, the "Clermont".

3. Watt

It is said that once when Watt was a child, he saw the boiling water on the stove boiling. The steam pushed the lid of the kettle open. Watt put the lid back, but it was quickly turned off again. Pushed open.

Watt kept putting the lid back and forth to find out why. Later, Watt realized that it was the power of steam, which sparked his interest in steam and led to the invention of the steam engine.

4. Lu Ban

Legend has it that Lu Ban invented the "hook" and "rejection" for the Chu navy. When the enemy was at a disadvantage, the "hook" could defeat the enemy. Hook the ship to prevent it from escaping; when the enemy is at an advantage, "reject" can block the enemy ship and prevent it from pursuing. With hooks and rejections, the Chu army was invincible, and Lu Ban was worthy of being a military expert.

One day, Lu Ban boasted to Mozi: "I have hooks and rejections for boat battles. Do you also have hooks and rejections for righteousness?" Mozi advocated peace and opposed war, and encouraged people to respect each other. , love each other, benevolence and righteousness are supreme.

He then replied: "I use love to hook and respect to reject. If you hook people with hooks, they will hook you; if you reject people, they will reject you with hooks. You Isn't the hook of 'yi' better than the hook of 'zhou'?" Lu Ban was speechless.

Lu Ban came up with another invention: a wooden magpie, which could fly for three days without landing. But Mozi said: "This wooden magpie is not as good as a cart harness that an ordinary craftsman can cut out in an instant. Once the cart harness is installed on the axle, the cart can carry fifty stones;

And your magpie What practical effect does it have? If a carpenter makes something that is beneficial to people, it is called cleverness, and if it is not beneficial to people, it can only be called clumsy." After hearing this, Lu Ban understood Mozi's philosophy.

Lu Ban once made a ladder to help the Chu Kingdom attack the Song Dynasty. Mozi came to stop the troops from sending out troops. In the palace of the King of Chu, he used clothes belts as a city and bamboo pieces as weapons to fight with Lu Ban. Lu Ban's siege equipment After all were exhausted, Mozi still had some ways to defend the city. In the end, Lu Ban was convinced and the King of Chu gave up attacking Song Dynasty.

5. Bell

Bell’s father is a voice physiologist and an expert in correcting speech and teaching deaf people.

Bell's grandfather was a philanthropist and had always been sympathetic to the deaf-mute disabled people. He often gathered some disabled people together and educated them affectionately. Therefore, the deaf and mute worshiped him as a savior.

After his grandfather passed away, his father inherited his legacy. In addition to educating deaf-mute people, he also studied methods of speaking and pronunciation, hoping to help these unfortunate people. Bell grew up in this environment, so he always hoped to make achievements in this area in the future.

One day, his father said to Bell in a gentle tone: "Child, the most painful things in the world are the blind, deaf and mute. They are human beings like us, but their eyes cannot see and their ears cannot hear. , the mouth cannot speak. Beautiful clothes and beautiful scenery cannot be seen by the blind;

Beautiful music and funny jokes cannot be heard by the deaf; we can talk and laugh freely and say whatever comes to mind, but they But we are deprived of this right. Thinking about it, we are so happy.

Therefore, in addition to thanking God, we must also do our best to help them, comfort them, and make them as happy as possible. Be able to live a normal life. Child, when you grow up, you must save these unfortunate people!"

Bell often heard this teaching, so he regarded himself as a deaf-mute throughout his life. Work hard for happiness and achieve your greatest ambition.

Bell has a kind heart and a flexible mind. He has developed a high degree of love and sharp brainpower since he was a child.

There was a water mill near his home, and a father and son lived in it.

Usually, some menial jobs are performed by young people. Later, the young people were drafted into the army, leaving the old people to grind flour alone to make ends meet.

When there was little water, the water wheel could not move, and the old man could not grind flour, so he had to go hungry. Bell saw it and sympathized with him, so he invited some children to help.

When there is a shortage of water, the work of grinding powder is really not easy. Everyone must push hard together to push the stone mill. At first, everyone thought it was fun and were willing to help. Later, when they got tired of it, they left one after another, leaving Bell alone, so naturally he couldn't push it anymore.

Bell returned home and sat in his father's study thinking hard: How can he push the stone mill easily? After a month of research, he came up with a good idea.

First, the molars are improved to reduce friction, and then the round shape of the wheat grain is used to make the two sides touch each other. In this way, the rotation of the molars is much more flexible. In this way, not only did he do the mill owner a big favor, but the whole village also rushed to imitate it. Everyone felt that the improved stone mill was really convenient and easy to use.

As a result, Bell, who was only 15 years old, became an "invention prodigy" in the eyes of the whole village.

The story of Marie Curie’s childhood

Decades ago, there was a little girl named Manyia in Poland who was very attentive to her studies. No matter how noisy the surroundings were, it could not distract her attention. Once, Manya was doing her homework, and her sister and classmates sang, danced, and played games in front of her. Manya acted as if she hadn't seen it, and was reading intently on the side.

My sister and classmates wanted to test her. They quietly set up a few stools behind Manya. As long as Manya moved, the stools would fall down. Time passed minute by minute, Manya finished reading a book, and the stool was still upright.

From then on, her sister and classmates no longer teased her, and like Manya, they concentrated on reading and studying seriously.

When Manya grew up, she became a great scientist. She is Madame Curie

Pasteur made great contributions to the prevention and treatment of diseases for humans and livestock and poultry raised by humans. For excellence in science. As a result, he enjoyed a high reputation throughout Europe. The University of Bonn in Germany solemnly awarded this scholar an honorary degree certificate. However, after the Franco-Prussian War broke out, Germany occupied French territory. Out of his deep feelings for his motherland and his great hatred for the invader Germany, Pasteur resolutely returned the honorary degree certificate to the University of Bonn

Robert Boyle continued his experiments with glass pistons and discovered many noteworthy things. When he applies double the pressure to the blocked air, the volume of the air will be reduced by half; when he applies triple the pressure, the volume will become 1/3 of its original size. When squeezed, the change in volume of air is always proportional to the change in pressure. He created a simple mathematical equation to express this proportional relationship, which we now call "Boyle's Law."

Priestley is studious and has a wide range of interests. He once studied ancient literature and mathematics. Introduction to natural philosophy, etc. Later, due to frailty and illness, he interrupted his studies for a period. After recovering, he entered the non-state religion college in Coventry. Because he studied diligently and had excellent grades, the school allowed him to be exempted from taking some courses in the first and second grades. In his later studies, he felt deeply that his foundation in mathematics and German was too poor, and he actively asked the school to allow him to make up for these two subjects.

Benjamin Franklin came up with the idea of ??inventing the lightning rod by chance:

Franklin’s most famous discovery is the unification of Electricity from the sky and electricity from the earth dispelled people's superstition about thunder and lightning. During the discharge experiment using the Leyden jar, Franklin faced the flash and crackle of electric sparks and could not help but associate it with the thunder and lightning in the sky. He realized that the electric sparks in the Leyden jar might be a kind of small thunder and lightning. . To test this idea, lightning from the sky must be brought to the ground. On a thunderstorm day in July 1752, Franklin made a large kite out of silk. A thin iron wire was placed on the top of the kite, and the iron wires were connected to the ground with silk threads. A copper key was tied to the end of the silk thread. The key is in a Leyden jar. Franklin put the kite into the sky, and a burst of lightning struck down, and all the hairs on the silk thread stood up. When he put his hand close to the copper key, electric sparks were emitted. Tiandian was finally captured. Franklin discovered that the Leyden jar storing electricity from the sky can produce all the phenomena that electricity from the earth can produce, which proves that electricity from the sky and electricity from the earth are the same. In 1747, Franklin discovered the phenomenon that tips are more likely to discharge from the Leyden jar experiment. After he discovered the unity of sky electricity and earth electricity, he immediately thought of using the tip discharge principle to introduce powerful lightning from the sky into the ground. To prevent buildings from being struck by lightning. In 1760, Franklin erected a lightning rod on a building in Philadelphia, and the effect was very significant.

Newton discovered the law of universal gravitation when he was killed by an apple.

: Once, Newton was doing experiments in the laboratory and forgot the time to eat. The assistant took some eggs and asked Newton to cook them himself. Newton took the small pot, put the eggs in the pot, put it on the stove and started experimenting again. After finishing the experiment, he remembered the eggs in the pot. When he opened the lid of the pot, he saw that there were no eggs inside, only a pocket watch. It turned out that Newton was too focused on doing the experiment and ended up boiling the pocket watch as an egg.

Einstein

In the spring of 1895, Einstein was 16 years old. According to German law at the time, boys who left Germany before the age of 17 did not have to return to serve in the military. Due to his deep hatred of militarism and the fact that he could no longer bear to be alone in the military-like Luipold High School, Einstein decided to leave Germany without consulting his parents and reunite with his parents in Italy.

However, what should I do if I drop out of school and cannot get a diploma in the future? Einstein, who had always been honest and simple, came up with an idea that he thought was a good one in desperation. He asked his math teacher to give him a certificate saying that he had excellent math scores and had already reached the college level. He also got a sick leave certificate from a familiar doctor, saying that he had a nervous breakdown and needed to go home to rest. Einstein thought that with these two proofs, he could escape from this disgusting place.

Unexpectedly, before he applied, the dean of students called him in and ordered him to drop out of school on the grounds that he had ruined the class spirit and failed to abide by school discipline.

Einstein blushed. No matter what the reason was, as long as he could leave this middle school, he was willing to do so and didn't care about anything else. He just suddenly felt guilty for having come up with a cunning idea that he never implemented. Later, Einstein felt guilty every time he mentioned it. Perhaps this kind of thing is too far away from his frank and sincere personality.

Newton was alone in the orchard at home. As he was walking and thinking about a problem, he accidentally bumped into an apple tree in the orchard. At this time, an apple hit Newton on the head. Newton suddenly woke up from the problem and picked up the apple. At this time, he fell into another question: why did the apple fall to the ground instead of floating into the sky? In the end, Newton proposed a universal law that produces the simplest phenomenon: universal gravitation.
