No matter in school or in society, everyone is familiar with composition. Composition is a comprehensive and creative speech activity. How to write a thoughtful and literary composition? These are some stories of Edison that I collected. Welcome to reading. I hope you will like them.

Edison invented the light bulb,

Before the invention of light bulbs a long time ago, many people generally used candle lamps and kerosene lamps for lighting at night, which made people's lives feel inconvenient. At that time, Edison was very upset. He is determined to invent a durable and bright light bulb. So Edison continued to do experiments with various materials in the laboratory. He experimented with a carbon ribbon, but this material is too fragile to be used as a light bulb material. After his failure, he began to experiment with ruthenium and chromium. When the light bulb lit up, he was very happy and thought that this material was very suitable for making the filament of the light bulb, but the filament burned out in about a few minutes.

A few years later, Edison's failed experience was laughed at by many people, thinking that he was daydreaming, especially Edison did many failed experiments. In the face of others' doubts and distrust, Edison did not give up the filament experiment plan. Instead, I continued my own scientific experiment with this as the driving force, so I tried to use carbonized cotton swabs as filament material to vacuum the bulb. This substance lasted for a long time, but it soon burned out after 45 hours, but Edison was already excited. He has tried more than 6000 experiments, and this time it is undoubtedly to find a breakthrough.

Edison started the filament experiment again, and everything paid off. He found that tungsten wire can be used as electric lamp material, so he was ecstatic. This material is an excellent material for making light bulbs, which emits very bright light, is not easy to burn out and is suitable for long-term use. In this way, the light bulb will gradually enter the homes of ordinary people and become an indispensable lighting tool for us at night.

1. Hatching experience

Edison liked to think when he was a child, and his curiosity was particularly strong. One morning, the whole family suddenly found Edison missing and couldn't find him anywhere. It was not until the evening that he was found lying next to the henhouse with a lot of eggs under his stomach. It turned out that he was whimsical and wanted to hatch chickens with his own body, but it backfired: the eggshell was broken and the yolk was bright. Little Edison also understood that chickens can hatch eggs, but for some reason, people can't hatch eggs.

2. The worst student

Edison likes to know what he is interested in. But going to school is another matter. Edison went to school at the age of eight, not long after his family moved to Port Huron, another big lake. Trapped in the classroom all day, he felt bored. Like most teachers at that time, the teachers in this school also believed in stick education. Edison was very afraid of rattan, even so, he still couldn't learn much knowledge taught by his teacher. His curious habit made the teacher even angrier. Edison became the worst student in the class for three months in a row. Later, he heard the teacher talking about him, saying that he had a problem and that he was "confused". Edison knew what this meant: a bad egg is a bad egg. In a rage, he rushed out of the classroom and never wanted to go back. At home, his mother Nancy stood beside him. For a time, Edison went to other schools intermittently. But most of the time, his mother taught him by herself. In other words, she asked him to teach himself. Encouraged by her, he eagerly read books: Shakespeare, history and the Bible. When he was 9 years old, one day, she gave him a book about science, which was the first time he read such a book. This book, called School of Natural Philosophy, allows readers to do some simple experiments at home. Since then, Al's life has changed. He read the book, did all the experiments in it, and then started his own experiment. He bought chemicals, looked around for waste such as wires and set up a laboratory in his bedroom. One of his experiments is to put the tails of two big cats on wires and let their hairs rub against each other, trying to generate static electricity. The only result is that he was beaten bloody by two cats! Another of his early experiments was to let a friend take a large dose of foaming powder, hoping that the gas generated by this powder in the human body would send him to the sky like a balloon full of gas.

Perseverance

Eddie started his hard career at the age of 12. He worked as a "newsboy" on the train, learned the technology of delivering newspapers, and went to Boston and new york. It was not until he was 24 years old that he had his own factory and a happy family. Edison announced in 1878 that he would invent a safe electric lamp with soft light and low price. In order to find a suitable filament, Edison tried boron, ruthenium, chromium, carbon essence and various metal alloys, totaling 1600, which lasted for 13 months, but all failed. Someone blew a cold wind and said that Edison "ate something that could not be chewed" this time. A physicist who once worked for Edison called this experiment "looking for a needle in a haystack". However, Edison was not afraid of failure, insisted on the experiment and made up his mind to fish out a needle from the sea. Where there is a will, there is a way. 1879 65438+1October 10 At 5 pm on Sunday, Edison lit the light bulb with carbonized cotton thread. He personally observed and recorded it. This time, the light bulb is bright and stable, 1 hour, 2 hours, 3 hours, ... The light bulb is always on. From 19 and 20 to 2 1, no one went to rest. Until 2 1 2 pm, Edison asked his assistant to raise the voltage a little, and the light bulb was brighter at the 45th hour. After a few minutes, the filament finally burned out. The New York Herald Tribune reported the success of the light bulb experiment in a full page. Edison got all the patents, and it is recognized that he invented the incandescent lamp. /kloc-On New Year's Eve in 0/879, Edison lit 60 light bulbs and hung them in Monroe Park. It was snowing heavily, and more than 3000 people came to visit it. Edison was a pragmatic man. His motto is: "I seek what human beings need, and then I will take a step forward and try to invent it." Some people say that invention is the product of fate and Edison is a genius. Edison sighed and said, "Genius is one percent inspiration and ninety-nine percent perspiration!" " When someone asked him how he persisted in inventing the light bulb after 654.38 million failures, he said that he had never failed in this process; On the contrary, he found 6.5438+0 million invalid methods. The 3,400 notes he wrote in his life recorded the inventive ideas and experiments in detail, which is a strong evidence of this passage. When Edison was 77 years old, someone asked him, "When will you retire?" He blurted out, "The day before my funeral!" Once, someone asked Edison half jokingly, "Do you agree to give science ten annual holidays?" Edison replied seriously: "Science will never take a day off. It has been working every minute for hundreds of millions of years, and it will continue to work like this. " Indeed, Edison fulfilled his promise. He is over 80 years old. In order to "make more inventions", he is still working diligently to extract latex from weeds in his country.

4. Wandering years

Another time Edison lost his job because he used his invention in the wrong place-at that time, he worked as a night shift operator in the railway bureau. According to the regulations of the Railway Bureau, after 9 pm, the operator should send a signal to the train service center every hour to prevent the staff from sleeping lazy. So Edison made an automatic timing transmitter, which made Edison the most punctual and reliable transmitter in the whole situation. However, during an inspection, the train service director found Edison asleep, a delicate machine. Although the director appreciated his talent, the railway bureau needed an honest and quiet person, not an inventor, so Edison was fired again!

Before 2 1 year-old, Edison changed jobs frequently and ran around in some telecom and telegraph companies until he came to new york. With his mechanical knowledge and excellent maintenance technology, he slowly became famous and set up his own engineering company, specializing in manufacturing and improving some commercial machines, such as gold market monitors, stock market monitors, gold price printing machines and other commercial machines, while developing and contracting various scientific instruments. 5. Young inventors

Edison once saved the children of Marvin clermont station master. In order to repay Edison, the stationmaster taught him telegraph technology and made him a telegraph technician. Edison soon went to the telegraph office as a telegraph operator. Because he worked at night, he could do experiments during the day. The telegraph office stipulated that he should send a letter to each other every hour. In order to sleep, he invented a machine that can automatically send telegrams to help him post letters, but he was finally found and dismissed. In this way, Edison often lost his job and became a wandering telecom mechanic, and his life was very unstable. One day, he heard the good news that South America was recruiting telecom technicians, but when they were going to South America, an old uncle told them that it was not good there, so the idea of going to South America disappeared, so he returned to his hometown-Port of Rest. During his wandering, Edison also studied hard, did experiments, studied and worked for him.

During Edison's return to China, his good friend Adams helped him find a job as a telecom mechanic in Boston, where Edison invented the automatic voting machine, which was Edison's first patented invention. Automatic voting machine is a machine with green and red buttons. Press the green button for "Yes" and the red button for "No". After the machine was finished, he went to Washington to do experiments with the machine. After arriving in Washington, the experimental results were very good, but members of the Committee still told Edison that the machine was not very practical. Sitting on the train home, he thought that "most of the inventions that inventors come up with in their minds are not practical, and only inventions that naturally arise from social needs are meaningful." Edison's first invention, though it failed in this way, taught Edison a valuable lesson. He became a successful inventor in the future because of the policies established at that time. Edison continued to work hard and create his world for his curiosity and thirst for knowledge.
