Edison only attended primary school for three months in his life, and his knowledge came from his mother's teaching and self-study. His success should be attributed to his mother's understanding and patient teaching since childhood, which made Edison, who was originally considered an imbecile, become a world-famous "king of invention" when he grew up.

Edison was curious about many things since he was a child, and he liked to try it himself until he understood the truth. When he grew up, he devoted himself to research and invention according to his interest in this field. He established a laboratory in New Jersey, and invented the electric light, telegraph, phonograph, film machine, magnetic mineral analyzer, crusher and so on for more than 2000 kinds of things in his life. Edison's strong research spirit made him make great contributions to the improvement of human lifestyle.

"Waste, the biggest waste is wasting time." Edison often said to his assistant. "Life is short, so we should try to do more with less time."

One day, Edison was working in the laboratory. He handed his assistant an empty glass bulb without a lampholder and said, "Measure the capacity of the bulb." He bowed his head to work again.

After a long time, he asked, "What's the capacity?" He didn't hear the answer, turned to see the assistant measuring the circumference and inclination of the light bulb with a soft ruler, and poured the measured figures on the table for calculation. He said, "Time, time, why does it take so much time?" Edison came over, picked up the empty light bulb, filled it with water, handed it to his assistant, and said, "Pour the water into the measuring cup and tell me its capacity at once."

The assistant read out the numbers at once.

Edison said, "How easy it is to measure. It is both accurate and time-saving. Why didn't you think of that? " ? Still counting. Isn't that a waste of time? "

The assistant's face turned red.

Edison murmured, "Life is too short, too short. Save time and do more! " "

Edison was a poor worker before he became famous. Once, his old friend met him in the street and said with concern, "look, this coat on you is very worn." You should get a new one. "

"Need it to be? Nobody knows me in new york. " Edison answered indifferently.

A few years later, Edison became a great inventor.

One day, Edison met that friend again in the street of new york. "Oh," exclaimed my friend, "why are you still wearing this old coat? This time, I have to change a new one anyway! "

"Need it to be? Everyone here already knows me. " Edison still answered casually.

The story of Edison

One snowy night, Edison's mother suddenly fell ill, and his father hurried to call a doctor. The doctor said, "Your mother has acute appendicitis and needs surgery." . At that time, there were only oil lamps without electric lights, and the light of oil lamps was very dim, so if you were not careful, you would open the wrong knife. Edison suddenly had a good idea. He took out all the oil lamps at home and put a mirror behind him to let the doctor finish the operation smoothly. The doctor said, "Son, you saved your mother with your wisdom and cleverness." Edison took his mother's hand and said, "Mom, I want to be the sun at night."

"magic" place

1one morning in the autumn of 877, Edison came to the editorial department of a magazine in new york from a place called Mero. He held it carefully.

Strange little things. This little thing has a long metal bar on it, with a big wheel at one end and a small handle at the other. Edison turned the crank, and then

Wrap a small piece of tin foil around the cylinder, put a small needle on it and sing a baby hypnosis song to the cylinder. After the action, the machine turned again, word for word.

Hypnotic songs are sung again. It is not enough to describe the first feeling of the people present at that time, only to say surprise. People were so happy that everyone in the editorial department shouted at each other.

Tell him Edison brought a talking monster. In a short time, reporters from newspapers in the city flocked to see the world.

The latest strange machines crowded the newspapers for a time. Once this invention came out, it aroused the rapid and huge fanaticism of the society for several months at that time. The railway specially opened a special car to participate.

Many people didn't believe this invention at first, and suspected that he hid the talking things in it first to deceive people. The bishop of a church recited to the radio at the highest speed.

A series of special nouns in the Bible. When these nouns are repeated word for word from the machine, they believe that there is nothing false.

This is the scene when the world's first phonograph came out. While people are admiring, they all call the inventor Edison "the devil". In fact, the nickname "demon" is far away.

Not from the invention of the phonograph, but from his life. Because he has many inventions. Electric light, telephone, film, telegraph, power generation

Machine, storage battery, typewriter, magnet separator, pressure gauge, etc. , is his invention. According to incomplete statistics, since he invented the first automatic counting machine in 1869.

By 19 10, he had obtained 1328 kinds of invention patents, which means that he had an invention every eleven days during this period. Because of this, he is called.

It is natural to be a "demon".

However, where does the real magic of this "devil" figure come from? He himself said: "One point inspiration, ninety-nine points sweat." Stubborn perseverance, amazing

Diligence is his real magic.

Originated from teenagers

Thomas Edison 1847 was born in Oahu, USA. He has only been in primary school for three months. The school teacher called him "stupid", so did his relatives and friends.

Male ... but his mother didn't believe this, so she became his teacher and guided him to read some books. Before he was twelve years old, he finished reading many difficult books, and his father also quoted them.

Guide him to study Newton's principles. The education and influence of his family made him develop a diligent spirit and amazing perseverance from an early age.

Edison likes science very much. When he was very young, he stored hundreds of bottles in the cellar at home for various experiments and built a small laboratory. He usually scrimps and saves.

All the money spent was spent on chemical supplies and instruments. But the money alone could not meet the needs of the experiment, so he went to the train to sell newsboys. He cleans it every day.

Get on the bus in the morning and go home after nine o'clock in the evening. After finishing the experiment, you often can't rest until late at night. Later, he found that there was a smoking room in the luggage compartment of the train, so he left the cellar at home.

The laboratory experiment moved here and insisted on doing chemical experiments. Here, he also learned to use the printer shown here and can record local news by telegraph number.

I bought a newspaper. This newspaper is very popular and sells well. At this time, he was only twelve years old. One day, the train shook, the luggage slipped, and a phosphorus pole used in his experiment fell to the ground.

Next, the carriage immediately caught fire. The fire was put out by the people who rushed to the scene, but the conductor deafened his ears and caused lifelong disability. The conductor also put his "four-wheeled laboratory" and "

Everything in the travel printing room was kicked under the car.

Difficulties and setbacks did not affect Edison's determination to engage in scientific experiments. He built a laboratory at home. Being electrocuted and burning clothes are common in experiments. friendship

Next time, his face was badly burned by nitric acid. Nevertheless, he never loses heart. Edison's earliest efforts contributed a lot to his later inventions. But,

Like other great inventors, Edison's road was not smooth. He is a night telegraph operator. Spend a lot of energy in book stands and libraries. But due to several mistakes

Industry, finally had to go to new york to friends.

Edison took the trouble to come to new york. At this point, there is not even a penny in his pocket. He was so hungry that he had to beg for some tea. This is his arrival in New Zealand.

The first meal after the date. It took him a long time to find friends here, but all his friends were unemployed. People looked at Edison who was hungry and in rags.

sorry Later, he was allowed to spend the night in the battery room. There happens to be a communicator in the room that publishes the market price. On the morning of the third day he arrived, the machine broke down.

Obstacles, because he studied hard, he quickly helped others repair the machine and was left behind, which led to a job. Since then, he has worked hard and cooperated with others to carry out reforms.

The market price communication machine has appeared again. Soon, he opened a small factory to produce this kind of communication machine and gradually embarked on the road of scientific research.

Walk firmly

Electric light is not strange today. But before 1880, the electric lamp was only in its embryonic form and was the most popular arc lamp at that time. This kind of lamp is at the two poles of the battery.

Connect two charcoals to your head, touch the two poles after electrifying, and then separate them, and a flame will be generated between the two poles immediately. Because the two carbon poles are horizontal, there is hot air rising in the middle.

The flame between the two poles bends slightly upward like an arc or bow, so it is called an arc lamp. This kind of lamp has many disadvantages: it needs to replace the carbon rod constantly; Loud voice; Lighting facilities

Small size, easy to damage vision. Dirty air; Another big disadvantage is that reflow can only light the arc lamp. Some famous scientists at that time, including the inventor of arc lamp, were not.

I often admire this kind of lamp. However, in 1877, Edison began the experiment of transforming arc lamps, and proposed to divide the current (that is, there are many lamps at a current point) to change the arc light.

The lamp is a white light. The experiment should reach a satisfactory level. We must find a substance that can burn to white heat as the filament, which must be able to withstand the high temperature of 2000 degrees 1000 hours.

Above combustion. At the same time, the use method should be simple, can withstand the impact of daily use, and the price should be low. The turning on and off of one lamp cannot affect the turning on and off of any other lamp.

Maintain the relative independence of each lamp. This was a very bold idea at that time, which required great efforts to explore and experiment. Some scientists laughed at him as a fool and satirized him. "

Dream, brag ",and several scholars use mathematics to prove that his research is impossible to succeed. But Edison was always full of confidence in experiments. In order to select such a lamp

As for the materials used for silk, Edison first experimented with carbonized materials, and then failed to experiment with platinum-iridium alloy with high melting point. He also made 1600 grains of ore and seedlings.

Different experiments failed. But at this time, he and his assistants have made great progress, knowing that incandescent filament must be sealed in a highly vacuum glass ball (

I.e. light bulb) and is not easily dissolved. In this way, his experiment returned to carbon wire. He used all his energy, just for plants, to carbonize day and night.

There are more than 6000 kinds of carbonization tests. It's been three years since his experiment notebook has more than 200 books and more than 40,000 pages. He works eighteen or nine hours a day. each

At three or four in the morning, he slept under the experimental table with two or three books on his head. Sometimes he sleeps on the stool three or four times a day for only half an hour at a time.

Wake up and work energetically.

By the first half of 1880, Edison's incandescent lamp experiment was still inconclusive. One day, he tore a bamboo filament tied to the banana fan in the laboratory into filaments.

Carbonize and making into filament. The result is better than all previous experiments. This is Edison's earliest incandescent electric lamp-bamboo filament electric lamp. This kind of bamboo filament

The light has been on for many years. It was not until 1908 that tungsten was invented as a filament and was replaced. It was after this that Edison began to develop alkaline batteries, which was very difficult. His research.

Spirit is even more amazing. This kind of battery is used to provide power. He and a selected assistant studied hard for nearly ten years and experienced a lot.

For a moment, he thought he had reached his destination, but for a moment, he knew he was wrong. But Edison never wavered and started again. After about 50 thousand times

Test, write more than 150 test notes, and achieve the goal.

No secrets.

Edison was obsessed with scientific research, but never cared about his private affairs. It can be said that he is seventy-three. Didn't sleep well before; Even in old age

He still works no less than 16 to 18 hours a day. As soon as he started doing the experiment, he forgot to have a rest. Once in a while, I'm really tired. If I can't keep going, I'll have a rest.

So he also likes people with the same energy as him to be his assistants. On this day, a man who claimed that he couldn't sleep came to him for a job. Edison was very interested in this and was recognized.

Because this man is his ideal assistant. So I work with this "sleepless". However, after 60 hours of continuous work, the sleepless man couldn't support it any longer.

He fell asleep, and even the machine broke down, making a loud roar and not waking him up. Edison is still working tirelessly. At that time, Edison's tireless work spirit

He is so famous that many people envy him.

One day, Edison received a visitor. He insisted that the "monster" introduce the "secret" of tireless work. Edison thought it was interesting,

Because there is no secret in his tireless work, he told a joke and told visitors, "Just eat a rabbit every morning." That man believes.

I thought it was true. I got up and left, and I did it when I came back. However, after six weeks, the man was too tired to get up. He doesn't pay attention to dressing up, but he often wears it.

Wearing old clothes stained with chemicals, his habit was especially serious in his later years. Ordinary people think he is a cook, and newspapers often publish satirical articles about him. This just proves that

Ming devoted all his heart and energy to scientific research. 1872, when he was studying the automatic telegraph, he was fascinated by the experiment and his thoughts were highly concentrated. Once he needs it.

I have something urgent to do outside. But when someone asked him his name, he couldn't remember it at the moment. On the road of scientific research, Edison walked steadily and struggled internally.

It really took a lot of physical and mental effort.

On his 77th birthday, someone asked him what his philosophy of life was. He answered; "work! Reveal the secrets of nature and make it the eyes of mankind. " this is

However, the real motivation of his scientific research is not "secret".

Never satisfied

As we all know, Edison had more than 1000 inventions in his life, and some of them achieved amazing success. He is famous himself. However, he never

Indulging in his own inventions, he is constantly climbing new scientific fields, and at the same time, he is always negative about his inventions.

Improvement. He himself said, "I will never be satisfied." Endless learning and continuous improvement is another outstanding feature of Edison. The battery he invented succeeded.

After that, he set up a battery factory and mass-produced it, which has been selling well. But after a while, he found that there was something wrong with the battery, and he couldn't find the reason at the moment, so he decided.

I want to improve the battery. However, the improvement will take time and energy, and the factory will be closed, which may not only reduce his prestige in inventing batteries, but also suffer huge economic losses.

Loss. However, he decisively ordered the factory to close immediately. Many people are satisfied with his battery use and ask for more orders, but he won't accept it at all; Someone is financially

He is not afraid to put pressure on him. As a result, his improved battery was more successful than expected and soon sold well all over the country. His spirit, with "gold"

If jade is outside, it will be defeated. "There is a sharp contrast between businesses that cover up inferior goods. We have to win people's respect and praise.

Among his inventions, nothing shocked society at that time more than the phonograph. This is also his proud invention. He is deaf and can make up such a person.

The machine that makes the sound is already very shocking. But when Edison invented it, he changed it again and again. Ten years later, he took the phonograph down from the dust on the shelf and decided.

However, we should improve it. He really worked continuously for five days and nights before he succeeded. There are such figures that can fully prove his research spirit: he is just staying.

There are more than 100 phonograph invention patents. When we see today's phonograph, don't forget that it is permeated with Edison's countless painstaking efforts. if

You can't do it without an endless learning spirit.

Here, we might as well trace back two stories of his childhood. In his childhood, he once saw a hen hatch and give birth to a chick, which was wonderful, but not enough.

Afterwards, he also quietly saved some eggs and put them in the warehouse. He squatted on them, trying to give birth to chickens himself, so that the whole family could not find him for a while. After going to school at the age of seven

His strong thirst for knowledge and habit of delving into problems are more obvious. He always asks endless questions about what he touches and asks the teacher to explain.

Answer clearly. In this regard, teachers have a headache. Once in an arithmetic class, the teacher taught the students that two plus two equals four. Edison must make the teacher understand why two plus two.

Equal to four. Although the teacher gave him a general explanation, he still couldn't meet his requirements. Therefore, the teacher called him "stupid". Edison was not satisfied with what he had learned.

Know that always use your naive heart to explore the secrets of nature. However, his teacher failed to understand him. But decades later, Edison became a successful man.

Famous inventor.

Naturally, many of Edison's inventions would not be more scientific and perfect if they were not for his endless research and continuous improvement. He invented it.

This is true of phonographs, incandescent lamps, storage batteries, talking movies and so on. As he said after the success of the incandescent lamp experiment: "No invention is

Perfect, white-hot electric lights are no exception today. Light without heat is an ideal light, and it is still far from this realm now! "Edison will always open his mind.

The enterprising spirit is commendable.
