Telegraph, telephone and electric light are so common and common in today's advanced technology that no one will be surprised. But do you know how important these things were to people at that time and how ecstatic they were? Humans thus remembered their inventor-Edison.
Edison, known as the "King of Invention", is a famous American scientist and inventor. In his life, there were 1328 inventions registered in the patent office alone. How can a person who has only studied for three months have so many inventions? I think, if you have heard the story of "Edison incubating chickens", you will understand that his success stems from strong curiosity.
1847, Edison was born in a merchant family in Milan, Ohio, USA. Edison showed great curiosity when he was very young. Whenever he sees something he doesn't understand, he grabs the adult's skirts and keeps asking questions, insisting on asking ugly questions.
One day, he pointed to the hen that was hatching eggs and asked his mother, "Why is the hen sitting under her ass?" Mother said, "Oh, that's a chicken!" " "In the afternoon, Edison suddenly disappeared, and the family was anxious to look around and finally found him in the henhouse. It turned out that he was squatting in a chicken coop with a lot of eggs under his ass to hatch chickens! When his parents saw it, they were so distressed that they had to pull him out and wash his face and clothes. Another time, when he saw birds flying freely in the sky, he thought: Since birds can fly, why can't people fly? So, he found a kind of powder for his friends to eat, in order to let them fly into the sky. As a result, the little friend almost died, and Edison was severely beaten by his father.
Finally, Eddie grew up to 8 years old, and his parents sent him to a rural primary school, thinking that he could go to school safely from now on. Who knows, he still loves to get to the bottom of it, and often asks the teacher dumbfounded and embarrassed. Once in an arithmetic class, the teacher wrote "2+2=4" on the blackboard. Edison immediately stood up and asked, "Teacher, why is 2 plus 2 equal to 4?" This question puzzled the teacher. He thinks Edison is a troublemaker and always disagrees with his teacher. So Edison attended classes for three months and was driven home by the teacher.
Edison's mother is a great mother. She didn't blame her only son for being driven back. Instead, he decided to educate the child himself. When she found Edison curious and particularly interested in physics and chemistry, she bought him books about physics and chemistry experiments. Edison started the experiment on his own according to books. It can be said that this is Edison's enlightenment education in scientific inventions.
When he grew up, Edison learned radio transmitting and receiving technology. He got a job as a night shift operator at Stratford Railway Sub-bureau. According to the regulations, the night shift operator must send a signal to the train service director every hour after 9 pm, no matter what happens. In order to have a good rest at night and study and invent during the day, Edison designed a telegraph that can automatically send signals on time. This is the prototype of the telegram.
Soon after, he improved the telegraph. After many tests, a new type of telegraph was successfully trial-produced. Edison looked at the machine he invented and smiled with relief.
It should be said that every invention of Edison is closely related to his curiosity. After inventing the telegraph, he began to do telephone experiments. He found that the diaphragm in the microphone could vibrate with the sound, so he observed it carefully and made a detailed record in his notebook. Thus, a "talking machine" was made. When people heard the news, they all came to watch and called him "the greatest inventor". Therefore, curiosity is a prerequisite for a person to succeed and show his wisdom.
Not only famous scientists need curiosity, but we ordinary people also need curiosity to learn knowledge and achieve something. 199 1 In July, Guangming Daily Science and Technology Department conducted a questionnaire survey on 1 18 middle school students who won the National Youth Science and Technology Invention Competition. In the column of "Your main psychological characteristics", 92% of the students wrote "Strong curiosity". He Ji, a teenager from No.1 Middle School in Daoxian County, Lingling District, Hunan Province, couldn't help wondering when he went to the henhouse to get eggs one day: How can eggs be big or small? Is the big head first out of the matrix or the small head first out of the matrix In order to find out this problem, he rushed home immediately after school every day, squatted by the chicken shed and observed quietly, sometimes even forgot to eat dinner. After more than two months, He Qi finally found that the egg came out first. To this end, he wrote a paper, which was praised by many biologists. His discovery is actually a new discovery that has not been recorded in bird literature.
Being a talent requires curiosity, but being curious doesn't mean that you will become a talent. If you want to achieve something, you still need to work hard. Curiosity is like a seed. Without it, a towering tree cannot grow, and people without curiosity cannot invent or create anything. After the seeds are sown in black soil, they will gradually break through the soil and grow into pillars through watering and cultivation. With curiosity, sweat and hard work, you will certainly become a useful talent. Dr. Li Zhengdao, a famous contemporary physicist, said: "Curiosity is very important, and curiosity is indispensable for science. The reason is very simple. Only curiosity can ask questions and solve problems. The terrible thing is that you won't ask questions and take the first step. " Because curiosity is so important, many people call it the first virtue of successful people. For an ambitious and eager teenager, curiosity is the most precious thing.
Edison is a world-famous inventor. He is an American. When I was a child, I only went to school for three months because my family was poor. When he was eleven or twelve, he began to sell newspapers. 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 when 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 the 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.
Edison devoted all his life energy to the great cause of benefiting all mankind; I never think too much about clothes.
When he was a poor boy, one day, he met a friend in the street of new york.
"Look at the coat you are wearing. It's broken like this You should buy yourself a new coat! " The friend said.
"Need it to be? Nobody knows me in new york. " Edison answered indifferently.
A few years later, Edison became a great inventor. Once, he met that friend again in the street of new york.
"Ah, Mr. Edison!" The friend exclaimed, "I have to change a new coat this time anyway!" "
"Need it to be? Edison nonchalantly replied, "People here already know me. "

"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, but turned to see the assistant measuring the circumference and inclination of the light bulb with a soft ruler, holding the measured figures and bending over the table to calculate them. 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 it? " ? Still counting. Isn't that a waste of time? "
