The experience of incubating eggs
Edison would love in one's childhood, particularly strong curiosity, one morning, the family found that Edison suddenly disappeared, giving way to also can not find anywhere, always in the evening, only to find that he lie beside the henhouse, belly under a lot of eggs, originally he whimsical, use your body to hatch chickens, backfired: broken egg, egg yolk, brilliant. Little Edison also learned: chickens can incubate eggs, but for some reason, people can't incubate eggs.
2. Worst Student:
Edison liked to learn about things that interested him. But school is a different matter. Edison went to school at the age of eight, shortly after his family had moved to Port Huron, on another large lake. He felt rather bored being stuck in the classroom all day.
Like most teachers of the time, the teachers at this school believed in cudgelling. Edison was very afraid of vines. Nevertheless, he could not learn much of what his teacher taught him. And his inquiring habit made the teacher angry even more.
Edison remained the worst student in his class for three months. Then he heard the teacher say something was wrong with him, that he "addled." Edison knew what this meant: Addled eggs were bad, spoiled eggs. In a rage, he rushed out of the classroom, never willing to go back.
At home, his mother Nancy stood by him. There was a time when Edison went off and on to other schools. But most of the time it was his mother who taught him. Or rather, she left him to teach himself. Encouraged by her, he read voraciously: Shakespeare, history, the Bible. One day, when he was nine years old, she gave him a book on science for the first time. It's called "The School of Natural Philosophy," and it asks readers to do some simple experiments at home. Since then, Al's life has changed.
He read the book in a daze, did all the experiments in it, and then did his own experiment. He bought chemicals, searched for scraps of electricity, and set up a laboratory in his bedroom. One of his experiments involved placing two large cats' tails on a wire and rubbing their fur against each other in an attempt to generate static electricity. The only result was that he was scratched bloody by two cats!
Another of his early experiments involved giving a friend a large dose of foaming powder in the hope that the gas it produced in the body would send him skyward like a balloon full of air.
3, hard exploration, "needle in a haystack" finally succeeded:
Edison began his hard life when he was 12 years old. He worked as a newspaper boy on a fire truck and learned how to publish newspapers. He went to Boston and New York. In order to find a suitable filament, Edison experimented with more than 1,600 materials, including boron, ruthenium, chromium, carbon, and various metal alloys, for 13 months without success. Some blew in the cold wind and said that Edison had "eaten something he could not chew." A physicist who worked for Edison called the experiment "looking for a needle in a haystack." But Edison was not afraid of failure. He kept experimenting, determined to get the needle out of the sea. Everything comes to him who waits. On Sunday, October 10, 1879, at 5 p.m., Edison lit a light bulb with a carbonized cotton filament. This time, the bulbs were bright and stable for an hour, two hours,
3 hours... The light bulb stays on. From the 19th to the 20th to the 21st, no one went to rest. It was not until 2 p.m. on the 21st, when the light lasted for 45 hours, that Edison asked his assistant to increase the voltage and the bulb became brighter. After a few more minutes, the filament finally burnt out. On December 21st the New York Herald Tribune ran a full-page story detailing the success of the bulb experiment. Edison received all the patents and is credited with inventing the incandescent light bulb. On New Year's Eve 1879, Edison lit 60 light bulbs and hung them in Monroe Park. It was snowing so heavily that more than 3,000 people came to see them.
Edison was a practical man. His motto is: "I explore what man needs, and then I step forward and try to invent it." Some people say that invention is the product of fate, Edison is a genius. Edison exclaimed: "Genius is one percent inspiration and ninety-nine percent perspiration!" When asked how he kept going during his 10,000 failures to invent the light bulb, he said he had never failed in the process; Instead, he found 10,000 methods that didn't work. In his lifetime, he wrote 3, 400 notebooks detailing his ideas for inventions and experiments. When Edison was seventy-seven, he was asked, "When will you retire?" "The day before my funeral!" he blurted out. At one point, Edison was asked, only half-jokingly, "Would you agree to a ten-year sabbatical from science?" Edison replied seriously, "Science does not rest for a day. It has been working every minute of the past hundreds of millions of years and will continue to do so." Indeed, Edison lived up to his promise. He was in his eighties and still worked hard to "invent more.
