Stories about Edison 8 Stories about Edison 1

He was permanently expelled from school after less than 3 months of schooling; he had his own laboratory at the age of 10 and started He started his invention and creation career; at the age of 15, he was slapped by an angry train conductor and became deaf in his right ear; at the age of 30, he had completed the research on the quadruple telegraph device and invented the phonograph... The life of the great inventor Thomas Alva Edison continued to give People bring surprises, and the hardships in his early years show us the persistence and strength of a great inventor. Known as a public hero, Edison made more than 2000 inventions in his life. There are 1,093 patented inventions alone. It is hard to imagine how dark our lives would be without the electric light he invented; without the movie projector he invented, how much joy our lives would lose.

There is a poor family in Milan, Ohio, USA. The family mainly makes a living by farming. On February 11, 1847, a baby's cry broke the family's peaceful life, and Edison was born. He has had a "problem" since he was a child. He always asks questions about everything and wants to try everything himself. His little head is filled with curiosity about the world. Once, because of his strong curiosity about fire, he lit fires again and again to observe "what was going on with the fire." As a result, he set fire to his neighbor's granary. While this "problem" brought him disaster, it also opened doors to the unknown world for him.

At the age of 7, Edison went to school. In school, Edison still asked all kinds of weird questions like he did at home, and these weird questions could not be answered by the teacher, such as "Why 2 plus 2 equals 4" and so on. The teachers at the school were not like Edison's parents because they understood his nature and did not punish him severely. On the contrary, the teachers believed that Edison was either an imbecile or a troublemaker, so when Edison was in school for less than 3 months, he was forced to be punished forever. left the school.

Fortunately, Edison’s mother Nancy was a primary school teacher. She not only patiently answered all the questions raised by her son, but also told him many interesting stories and recommended many books for him to read. The "Nature Reader" she recommended was Edison's favorite book because it introduced many physics and chemistry experiments. This book was also the first scientific book that Edison, who was less than 10 years old at the time, read.

Because life at home became increasingly poor, Edison, at the age of 11, entered the society and began to make a living on his own. He first helped others sell flowers, and later became a newsboy. Most of the money he earned was used to support his family, and only a small amount was left to buy books and chemicals.

There is a library at the end of the train where Edison sells newspapers. Edison always goes there to read when the train stops at the station. At the age of 12, he had already read "The Rise and Fall of the Roman Empire" written by the British historian Gibbon and "History of Britain" written by Hume. "Books are endless, but human life is limited. You have to choose a goal, and then read selectively around this goal." These words of the library staff let little Edison know how to read books.

The "problem" of Edison's "Rejoice Experiment" did not change because he entered society, but instead became worse. He begged the conductor to allow him to conduct experiments in a corner of the baggage car after selling the newspapers. The conductor agreed. When Edison was immersed in the happiness of being able to experiment in his free time, something unfortunate happened. One day, Edison's bottle containing pornographic materials overturned due to a bumpy train, and the yellow powder spilled out and caused spontaneous combustion. With the combined efforts of Edison and the conductor, the fire was put out. Although it did not cause a fire, a slap from the train conductor left the 15-year-old Edison permanently deaf in his right ear, and Edison also ended his newspaper selling career.

There is always a road ahead. Later, Edison was grateful to the stationmaster for saving his son. In order to repay Edison for saving his son's life, the stationmaster who had been a telegraph operator taught Edison the technique of sending and receiving telegraphs. In just 4 months, Edison was able to complete this job brilliantly. Railway telegraph operators work 12-hour shifts, and there is a night shift every two days. Edison's love for experiments made him reluctant to waste his off-duty time on rest, so he often fell asleep while at work.

At that time, the Railway Bureau stipulated that night shift telegraph operators must send a signal to the bureau every hour. This was stipulated to prevent the on-duty personnel from sleeping and missing work. After repeated trials, Edison finally connected the telegraph machine to the chime clock, so that when the chime clock struck time, it would drive the telegraph machine to send a signal to the bureau. But the good times didn't last long. The bureau discovered Edison's "lazy" behavior. This genius invention caused Edison to lose his job.

After losing his job, Edison shuttled back and forth between various stations, because despite his impeccable skills in sending and receiving telegraphs, he was often fired by the stations for "not doing his job properly". Because the workbench Edison once used was filled with his work tools.

In order to record the sparks of inspiration that came out of his brain in a notebook, he would always ask the other party to interrupt the telegram or simply forget about the telegram that should be sent, so he was fired from the station again and again. . On another occasion, he spilled the sulfuric acid used in the experiment on the expensive carpet in the stationmaster's office. The webmaster was so angry that he fired him immediately.

Although he was often fired, Edison was always thinking about and practicing how to send and receive telegraphs. His skills became more and more sophisticated and he became more and more famous. He was often assigned to send and receive faster news telegrams. He was recommended by a friend to work for the then-famous Western Union Telegraph Company in Boston. As soon as Edison reported for duty, he was called to receive major news telegrams from New York. Their purpose was to see what this young man's skills were. Edison responded calmly and calmly dealt with the sender's deliberate difficulties - in the process of the other party transmitting the telegram, there was a series of ambiguous digital signals mixed in. When Edison handed in the telegraph manuscript, his colleagues were surprised to see that the ambiguous numbers were translated clearly and accurately. As a result, the "quick and accurate telegraph operator" became the "quick and accurate telegraph operator" among his colleagues. A title for a person who is not doing his job properly.

Reading and doing experiments are two hobbies that Edison could not give up no matter what. No matter how hard life was, even if he was wandering, even if he borrowed money from friends to survive, he still insisted on doing experiments. He was very stingy about things other than studying and doing experiments. He was reluctant to spend money on things other than studying and doing experiments. He always spent all his money after midnight on buying raw materials and book boxes. Edison was never willing to buy clothes for himself. "God does not allow me to spend so much money on clothes." This is what he said when the sulfuric acid burned the clothes he had just bought for 30 yuan. Edison was very stingy about buying clothes, but he was very generous about spending money on books and experiments. He only spent 4 hours sleeping every day. When he got the book that helped him the most in his life - "Faraday's Electrical Research", he put all his attention on this book. A few years later, his sweat finally blossomed into success.

At the age of 21, Edison invented the voting recording machine, his first invention in his life. Although he was heavily in debt for this invention, no one bought the patent for this invention. Being poor, he always walked around the machine that reported stock prices on the New York Stock Exchange. One day, the machine suddenly malfunctioned. Just when the managers who couldn't figure out the problem were sweating with anxiety, Edison appeared. The words "Let me see" drew people's attention to him. In less than two hours, Edison had the machine working normally again, and people around him were marveling at him. The next day, after rigorous assessment, he became the director of the exchange's mechanical room with a relatively high monthly salary. Not long after, his new "stock quotation machine" came out, and he sold it at a price of 40,000 yuan. The invention was sold to the exchange. With this money, Edison could finally end his life of abject poverty and be better able to devote himself to the cause of invention and creation.

Soon, Edison, who loved experiments, resigned from his position at the exchange and first opened a small factory specializing in inventions. Later, he founded the world's first large-scale "invention factory" - an industrial laboratory. The establishment of an industrial laboratory allows many people to work on an invention together, and different people have different tasks, breaking the previous situation where scientists conducted scientific research alone. This pioneering work also opened up a new path for future scientific research.

In the summer of 1873, Edison got married. In the early morning of this day, he dressed up and hurried out of the door. Later, he hesitantly returned to the house and walked around restlessly. When his friends came to hurry him up, he remembered that he was going to attend his own wedding.

At this time, Edison spent almost all his time at work. He worked more than 20 hours a day and was very focused. Therefore, it was understandable that he forgot about his marriage.

Before the age of 30, Edison completed research on the quadruple telegraph device, overcame numerous obstacles, and finally developed a high-quality microphone and invented the phonograph, the "talking machine." "It's refreshing for everyone.

Edison made more than 20xx inventions in his life and was called the "King of Inventions in the World." However, because Edison did not receive a formal school education, he took many detours in the process of scientific research. This is a very pity. A famous physicist once said that Edison's experimental method was "looking for a needle in a haystack." But Edison's invention was witnessed by everyone, and his invention also greatly changed people's lives and brought light and joy to people. He is the well-deserved "King of Inventions in the World".

Edison (1847-1931) was a famous American inventor. He was studious, good at thinking, and worked hard all his life. At the age of 75, he still went to the laboratory to sign in on time every day. He worked almost ten hours a day for decades and read 3 to 5 hours in the study in the evening. If you use Calculating the activity time of an ordinary person's life, his life has been extended exponentially. Therefore, on Edison's 79th birthday, he proudly said to people, I am already 135 years old. He lived to the age of 84 and made as many as 1,100 inventions in his life. His greatest contribution was the invention of the phonograph and the automatic telegraph, and his experiments and improvements in incandescent lamps and telephones. Edison began to study electric lamps in his early 20s. Over a period of more than 10 years, he successively selected bamboo cotton, graphite, tantalum, etc., and thousands of different substances as filament materials for experiments. He often had great successes. On one occasion, he and his assistants actually continued to experiment. Work 5 days and nights. In 1879, Edison used carbon filament as an incandescent filament and ignited it for 40 hours. Because the surface of carbon wire is porous and brittle, its strength is very low. Soon replaced by tungsten wire.

In 1883, Edison discovered the phenomenon of thermionic emission, also known as the "Edison effect", that is, some electrons or ions near the metal surface cause them to move irregularly due to high temperature and obtain enough kinetic energy to overcome the constraints of the surface. , escape from the metal.

The Edison effect is crucial to the operation of all vacuum tubes. The cathode, which serves as the emitting surface, is often coated with a layer of alkaline earth metal oxide to facilitate electron emission, and is heated with electric current to maintain a high temperature.

In 1900, Edison invented the iron-nickel battery, which is an alkaline battery with an electromotive force of about 1.3 to 1.4 volts and a long life, but its efficiency is not high. Edison made many inventions in his life, but when others asked Edison the reason for his success, he said: Some people think that I have some genius, which is incorrect. "Genius" is one percent inspiration and ninety percent hard work. . Story about Edison 4

Students, do you know Edison? Through studying today, I learned many stories about Edison.

Edison was born on February 11, 1847, in the small town of Milan in the Midwestern United States. He died on October 18, 1931. Edison made about 2,000 inventions during his lifetime, making great contributions to human civilization and progress. It is said that the IQ is 160. So far, no one has been able to break his record of holding 1,099 invention patents. People call him the "King of Inventions."

Edison only attended elementary school for three months in his life. His knowledge was obtained through his mother's teaching and self-study. His success should also be attributed to his mother's understanding and patient teachings from an early age. Edison, who was originally considered an imbecile, became a world-famous "invention king" when he grew up.

Someone has made statistics: Edison’s inventions in his lifetime were officially registered in the patent office, with about 1,300 inventions. 1881 was his record year for inventions. This year, he applied for registration of 141 inventions, with an average of one new invention every three days.

Edison’s three major inventions: the phonograph, the electric light and the movie camera, enriched and improved human civilization. Edison's achievements are inseparable from his curiosity.

Now let me tell you a few interesting things in Edison’s life.

Story 1: He started his initial experiment in his wooden shed

Edison liked to use his distinctive big brain to think about a series of problems since he was a child. When he saw the blacksmith burning iron in a raging fire and then hammering it into various tools, he shook his big head and asked one question after another: What is fire? Why does fire burn? Why is the fire so hot? Why does iron turn red after being burned in a fire? Why does iron become soft when it becomes red? Back home, little Edison began his first experiment in his woodshed. He brought hay and lit it, trying to figure out what fire was. However, little Edison's first experiment caused a fire and burned down the wooden shed at home.

Story 2: Even while sleeping, I am absorbing the nutrition from the book.

In order to conduct experiments, Edison often did not leave the laboratory or sleep for several days. I was really exhausted, so I took a nap on the experimental table using a book as a pillow. One day, his friend joked about him: "No wonder Edison knew so many inventions. It turned out that he was absorbing the nutrients in the book even while sleeping."

Story 3: Why can hens hatch babies? Chicken, can’t I?

Once, when it was time to eat, Edison was still not back. His parents were very anxious and looked around. It was not until evening that they found him in the hay shed next to the yard. When his father saw him lying motionless in the haystack with many eggs, he asked very strangely: "What are you doing?" Little Edison replied calmly: "I am hatching chicks!" It turned out that, When he saw a hen hatching chicks, he thought it was strange and wanted to try it himself. At that time, his father pulled him up in an angry and funny manner and told him that humans cannot hatch chicks. On the way home, he asked in confusion, "Why can hens hatch chicks, but I can't?"

Story 4: What's the secret in the wild honeycomb

< p>Because Edison was interested in many things, he often encountered danger. Once, when he went to a house where wheat was stored, he accidentally fell into the wheat store. The wheat buried his head and he could not move. He almost died, but fortunately someone found him in time and grabbed Edison's feet and pulled him out. Another time, he fell into the water and was pulled out like a drowned rat. He himself was quite frightened.

When he was 4 years old, he wanted to see what was hidden in a wild bee's nest on the fence, so he poked it with a branch. His face was so red and swollen that he could hardly open his eyes after being stung by a wild bee.

From these stories, I feel that Edison was a scientist who was good at thinking, studied hard, was not afraid of difficulties, was not afraid of danger, and was indomitable.

I particularly like two famous quotes by Edison. The first sentence is: Life is too short, there are too many things to do, and I have to race against time. The second sentence is: Failure is also what I need. It is as valuable to me as success. Only after I know all the ways to do a job poorly can I know the way to do a job well.

After listening to what I have said so much, you should know something about Edison, right? Are you, like me, full of admiration for Edison, the "King of Inventions"? Story about Edison 5

Edison began experiments to reform the arc lamp in 1877, proposing to divide the current and convert the arc lamp into a white light lamp. This test needs to be done satisfactorily. It is necessary to find a substance that can burn to white heat to make a filament. This filament must withstand burning at a temperature of 2,000 degrees for more than 1,000 hours. At the same time, it should be simple to use, able to withstand the bumps and bumps of daily use, and the price should be low. The turning on and off of one lamp should not affect the turning on and off of any other lamp, and the relative independence of each lamp should be maintained. In order to choose this kind of lamp. This was a very bold idea at the time and required great efforts to explore and test. As for the material used for filament, Edison first experimented with carbonized substances. After failure, he experimented with metal platinum and iridium high-melting point alloys for filament. He also conducted 1,600 different experiments with high-quality ore and ore seedlings. The results All failed. But by this time, he and his assistants had made great progress and knew that the incandescent filament must be sealed in a highly vacuumed glass ball to prevent it from melting. In this way, his experiments returned to carbon filaments. He worked day and night until the first half of 1880, but Edison's incandescent lamp experiment still had no results. One day, he tore a piece of bamboo silk tied to the edge of a banana fan in the laboratory into thin filaments, and devoted all his energy to carbonization. There were more than 6,000 carbonization experiments on plants alone. He has more than 200 experimental notebooks, totaling more than 40,000 pages, which took three years to complete. He works eighteen or nine hours a day. At three or four o'clock every morning, he would sleep under the experimental table with two or three books on his head. Sometimes he slept on the stool three or four times a day, for only half an hour each time.

By the first half of 1880, Edison's incandescent lamp experiments still had no results, and even his assistants were discouraged. One day, he tore a piece of bamboo silk tied to the edge of a banana fan in the laboratory into filaments, and then carbonized it to make a filament. The result this time was better than all the previous experiments. This was Edison's earliest experiment. The incandescent electric lamp invented - the bamboo filament electric lamp. This bamboo filament electric lamp continued for many years. It was not replaced until the invention of tungsten filament in 1908. The alkaline storage battery that Edison began to develop after this was very difficult, and his research spirit was even more amazing. This kind of battery is used to provide motive power. He and a selected assistant worked painstakingly for nearly ten years and experienced many hardships and failures. One moment he thought he had reached his destination, but the next moment he knew he was wrong. But Edison never wavered and started over. After about 50,000 tests and more than 150 test notes, the goal was achieved.

As we all know, Thomas Edison was a great inventor. He obtained 1,093 invention patents in his lifetime. He was the person who obtained the most individual patents since the patent system was implemented. His famous saying "Genius is ninety-nine percent hard work and one percent inspiration" has become a motto that inspires people to work hard. It can be said that Edison's contribution greatly changed human life. Of his many inventions, Edison considered the electric light the most important, but his favorite was the phonograph. The following is the process of the invention of electric light: Lamp is a great invention for mankind to conquer the night. Before the 19th century, people generally used oil lamps, candles, etc. for lighting. Before the advent of electric lights, the most commonly used lighting tools were kerosene lamps or gas lamps. Although this has broken through the night, it has not yet completely liberated mankind from the restrictions of the night. Only the birth of the generator enabled human beings to use various electric lights to brighten the world, turn night into day, expand the scope of human activities, and win more time to create wealth for society.

At the beginning of the 19th century, a British chemist made the world's first arc lamp. But this kind of light is too strong and can only be installed on streets or squares, and cannot be used by ordinary families. Countless scientists have racked their brains to create a cheap, high-quality, durable household electric light. The day has finally arrived. On October 21, 1879, an American inventor finally ignited the world's first practical electric lamp through long and repeated experiments. Since then, the name of this inventor, like the electric light he invented, has entered thousands of households. He was Edison, who was praised as the "King of Invention" by later generations.

Edison was an extremely diligent person who liked to do various experiments and created many ingenious machines. He was particularly interested in electrical appliances. Since Faraday invented the motor, Edison was determined to create electric lights and bring light to mankind.

In the process of inventing the electric light, Edison carefully summarized the failed experience of his predecessors in making electric lights. He experienced countless failures, but he was not discouraged and finally turned cotton yarn into charred charcoal. He carefully put the carbon filament into the glass bubble and tested it. The effect was indeed very good. The life of the light bulb was suddenly extended by 13 hours, and later reached 45 hours. In this way, the world's first carbon filament incandescent lamps came out. On New Year's Eve 1879, Lopack Street, where the Edison Electric Light Company was located, was brightly lit. Finally, Edison put the carbonized bamboo filament into a glass bulb. After powering on, the bamboo filament bulb lit up continuously for 1,200 hours!

The carbon filament electric lamp invented by Edison is similar to the one invented by Edison. Compared with the arc lamps of the past, they are undoubtedly much more practical. Its appearance marked the official beginning of the history of human use of electric lights. However, the brightness of this kind of carbon filament electric lamp is not ideal, the production method of the filament is relatively complicated, and the service life is not very long. Therefore, scientists from all over the world are working on improving incandescent lamps.

In 1909, 30 years after the birth of the carbon filament electric lamp, Kulicki of the General Electric Company of the United States invented an electric light bulb with tungsten filament. This kind of electric lamp is a step forward compared with carbon filament electric lamps, but because the tungsten filament easily becomes brittle after being energized, its service life is also affected. Story about Edison 6

I have been reading the book "The Story of Edison the Greatest Inventor" at home these days, and I feel very deeply.

Edison is a legend in the scientific community - although he did not receive a good school education, he achieved great success through personal struggle and extraordinary intelligence. He is self-taught, and with perseverance, rare enthusiasm and energy, he stood up from thousands of failures and completed more than 1,100 inventions. Today's electric lights, telephones, movies, etc., he brought to the world Light brings a happy life to our descendants.

Think about our current children. Most of them are pampered and give up when they encounter difficulties and setbacks. However, Edison stood up despite thousands of failures and completed so many inventions. Now that we live in such a happy era, we should work hard, not be afraid of difficulties, persist, persist, persist, and keep moving forward in the footsteps of great ancestors like Edison!

What saddens and touches me the most Once, when the train started, Edison had not yet got on the train. When he reached the door of the last train, he jumped up and wanted to jump on the pedal. In order to help him, a conductor caught him with both hands. Due to excessive force, Edison's ears could no longer hear any sound. This physiological defect accompanied him throughout his life.

Edison devoted everything he had to realizing his ideal. How much courage does this kind of selfless dedication require? But we don’t even know how to wash our own clothes at home, and our homework and homework must be completed under the constant supervision of teachers and parents. We have no shortage of food and clothing. In a materially rich society, we should encourage ourselves to study hard and learn not to waste our time from an early age. Start from me, start from now, and be a person of value to society and mankind.

Edison will be my eternal role model! Story about Edison 7

Once, when he saw a hen hatching eggs, he curiously asked his mother: "Why does the hen hatch? Are you lying on the egg and not moving? Are you sick?" His mother told him that he was hatching chicks, and after some time, a baby chick would emerge from the eggshell.

"

After listening to his mother's words, Edison felt very novel. He thought, a hen can hatch chicks by lying on an egg. How does an egg become a chick? People lie on it. Can it work? He decided to give it a try. Edison brought a few eggs from home and found a secluded place at a neighbor's house. He first built a nest, spread it with soft thatch, and then laid out the eggs. Squatting on it, he wanted to see with his own eyes how the eggs hatched into chicks. It was getting dark and Edison hadn't come home yet, so everyone at home was very anxious, so they looked around for him. Only then did they find Edison sitting on a grass nest motionless, with a lot of grass blades on his body and head. When his family saw him, they were angry and funny, and asked him: "Are you there?" What are you doing here?" "I'm incubating eggs here! The chicks are about to hatch. "What kind of eggs are you hatching? Come out quickly!" Dad shouted loudly. "The hen can hatch eggs. I want to see how to hatch chicks." "No, no! Go home quickly!" Dad shouted again.

Mom did not blame or tease him, because she knew the child's character. She smiled and said: "Human body temperature is not as high as that of a chicken." If your body temperature is high, you won't be able to hatch it if you hatch it like this. "Although Edison did not hatch the chicken, he increased his knowledge through this egg hatching activity. Story about Edison 8

Everyone knows that the reason why Edison dropped out of school was because Edison asked "Teacher, why? Plus one is two?" The teacher said, "Edison, if you take one pencil and add another pencil, wouldn't it become two pencils?" "But teacher, take the water from two cups and put it into the other cup. "The water is concentrated in a cup. How can one plus one be two?" The teacher didn't know how to answer. "Teacher, two pieces of mud stuck together become one piece. Why is one plus one two? Maybe one plus one is two." One is one. At this time the teacher got angry: "It's so annoying! You can go and think about it yourself." "So the teacher continued the class. Edison raised his hand again, "What's the matter, Edison?" The teacher suppressed his anger and asked. "Teacher, why does the wind blow?" "Teacher, why do eggs hatch chicks?" the teacher said. : “That’s because the hen warms the eggs. "Teacher, why can chicks hatch by heating eggs?" Edison asked many more reasons, such as "Why don't fishes drown?" "Why is the sky blue?"

The teacher finally couldn't bear the wait and scolded him severely: "It's so annoying, bastard, I'll just learn your arithmetic! Are you a fool? Reading like this is in vain." Edison went home crying. After listening to her son's story, the mother took Edison's hand and went to the school to find the teacher. She asked the teacher: Are you saying that my son is a fool and is reading in vain? The teacher was speechless. "I understand. My son can be educated by myself. No need to bother the teacher. Goodbye." Holding her son's hand and going home, Nancy thought as she walked, "Teacher Engel forced the child to memorize the textbook completely. My son The two of them reached an impasse because he felt disgusted. I didn't force him, I wanted to enjoy the joy of thinking with him. Go to hell! Memorizing textbooks is useless when you grow up. Living textbooks are not everywhere. Are they all?" Nancy vowed secretly: "I will try to give my son an education that will never lose to other children." From then on, Edison's family education began.
