Likes to ask questions
Edison was born in an American city. It has been more than one hundred years now. At that time, there were no cars, no movies, no radios and no electric lights. Edison often kept asking questions all day. One day, his father was impatient with the question and said, "You have really become my' big problem'! But Edison didn't stop asking questions because he was curious about everything.
When he grew up, he took some questions he asked as a child and studied them again, trying to find out the answers by himself. As a result, many of the answers he found became inventions. Edison invented many things in his life, the most important of which was the phonograph and movies. He also improved the electric light to drive away darkness and made outstanding contributions to mankind. Surprisingly, however, the world-famous "king of invention" only attended primary school for three months! His achievements in life come from his interest in things and the spirit of continuous learning.
Edison was full of curiosity about things he didn't know since he was a child. When he was four years old, he saw the hen lying on the eggs in the barn and tried to hatch the eggs like a hen. He lay in the henhouse all day, but the chicken was crushed. When the experiment failed, Edison began to cry in disappointment.
My mind is full of paste? & ltbr/>； & ltbr/>； Edison began to go to school. His teacher doesn't like Edison because he likes asking questions too much. One day, the teacher couldn't stand Edison's questions and shouted angrily, "Your questions are all stupid. I can't teach you any more, your mind is full of paste! When Edison's mother knew about it, she was very angry with the teacher. She believed in her son, so she took Edison home and taught him to teach himself.
Edison never went to school again, but by the time he was nine years old, he had read many books about science because of his mother's teaching experience and Edison's love of reading. These books changed his fate and made him determined to be a great inventor. Among all kinds of scientific knowledge he came into contact with, what interested him most was "electricity".
I can't hear you. Are you deaf?
Edison needed money to buy experimental materials and reference books. So when he was twelve years old, he began to work on the train, selling newspapers, sweets and sandwiches, and worked for more than ten hours every day. In order to save time, Edison set up a small laboratory in the smoking room of the train, and went in to do experiments whenever he had time. Who knows, once the train shook badly and knocked a glass bottle containing chemicals off the shelf and broke it. The carriage caught fire at once, and the conductor was very angry and gave Edison a slap in the face. From then on, Edison's right ear was deaf, and he could no longer hear the sound.
Invent the electric light
At that time, most people still used candles and oil lamps for lighting. Although someone invented a light that can emit light, it has many shortcomings and is easy to cause fire. Edison wanted to invent a completely different lamp. The light should be soft and not dazzling, not easy to put out, no noise and no danger.
Edison first put a carbon filament in a glass bulb and used electric heating, but the filament burned out because it was too hot. Edison later tried to experiment with metal wire, hemp thread and even straw and silk. Finally, it occurred to him that all the air in the glass bulb should be pumped out. After several experiments and failures, Edison finally chose bamboo as the filament. 1879 In June, Edison started the generator. The filament emits white light when heated. The light was on all night until the next day. The electric light without black smoke, glare and flash was finally invented by Edison.
In Edison's life, there were more than 1000 inventions. Someone asked the great inventor why there were so many inventions. He didn't answer directly, but took out a notebook with many wonderful design drawings and intermittent words. It turned out that once Edison had any new ideas, he immediately recorded them in his notebook. Edison died at the age of 84. In addition to the above-mentioned phonograph, electric light and movies, the telephone and tram, which are most closely related to our daily life, are his precious legacies to mankind.
