Hard work pays off

The story of Edison's invention of the electric light.

Before the advent of electric light, the common lighting tool used by people was kerosene lamps or gas lamps. Because they burn kerosene or gas, they have strong black smoke and a pungent odor, and they have to be fueled frequently, so they are very inconvenient. What's more serious is that this kind of lamp is easy to cause disasters and cause catastrophes.

For many years, many scientists have tried their best to invent a safe and convenient electric light.

At the beginning of the 19th century, a British chemist used 2,000 batteries and two charcoal rods to make the world's first arc lamp. But this light is too strong to be installed on streets or squares, and cannot be used by ordinary households. Countless scientists have racked their brains to create an inexpensive, high-quality, and long-lasting household electric light.

The day has finally come. On October 21, 1879, an American inventor finally lit the world's first practical electric light through a long period of trial and error. He is Edison, who was praised as the "King of Invention" by later generations.

Edison was born on February 11, 1847 in the town of Milan, Ohio, USA. He only studied in school for three months in his life, but he was diligent and diligent in thinking, and his invention created more than 1,000 kinds of achievements such as electric lights, gramophones, and movie cameras, and made significant contributions to mankind.

When Edison was 12 years old, he indulged in scientific experiments, and after tireless self-study and experiments, he began to invent the automatic telegraph, automatic ticket counting machine, typewriter, automatic ** machine and gramophone at the age of 16. In September 1878, Edison decided to attack the fortress of electric lighting. He read a lot of books on electric lighting and was determined to make electric lights that were cheap, durable, and safe.

In 1879, after several experiments, Edison finally decided to use charcoal filament as a filament. He sprinkled a piece of cotton silk with charcoal powder, bent it into a horseshoe shape, put it in a crucible and heated it, made a filament, put it in a light bulb, and then used an extractor to remove the air in the bulb, and the electric light was turned on, and it could be used continuously for 45 hours. In this way, the world's first incandescent lamps of carbon filament came out.

On Chinese New Year's Eve 1879, Lopac Street, the seat of the Edison Electric Light Company, was brightly lit.

In order to develop electric lights, Edison often worked more than ten hours a day in the laboratory, sometimes for several days in a row to experiment, after inventing carbon filament as filament, he successively tested more than 6,000 kinds of plant fibers, and finally selected bamboo wire, through high-temperature closed furnace coke, reprocessing, to obtain carbonized bamboo filament, installed in the bulb, once again improve the vacuum degree of the bulb, the lamp can be lit continuously for 1200 hours. The invention of the electric light caused gas** to plummet by 12% in 3 days.

Bamboo silk lamps have been used for many years. It was not until 1906 that Edison switched to tungsten filament, which improved the quality of the bulb and continues to be used today.

When people light the electric light, they always think of this great inventor, who brings endless light to the darkness.

Yuan Longping, the father of hybrid rice, needed to breed a male sterile rice plant, that is, a male sterile line, before he could cross with other varieties. This is a difficult problem for the world. Yuan Longping knew the difficulties, and he believed that the original parent of the male sterile line was a naturally mutated male sterile strain, which could also exist naturally.

China has a large number of wild rice and cultivated rice varieties, contains rich seed resources, is the free kingdom of rice, "foreign countries do not succeed, Chinese do not necessarily fail."

Yuan Longping opened his legs and walked into the reckless green sea of rice, looking for the male sterile strains of rice that had never been seen before, and had not been reported in Chinese and foreign sources. Time passed day by day, Yuan Longping had the scorching sun on his head, stepped on the mud under his feet, hunched over and bent over, and observed and searched one spike after ear. "Hard work pays off", and finally found a male flower anther does not crack on the 14th day, Yuan Longping was ecstatic.

As the saying goes: hard work pays off. As long as we study carefully, God will not treat us badly. But it's not that you have poor study habits or bad grades; If you skip school, you won't be productive, as long as you are willing to work hard, you can still succeed.

Edison is a famous inventor, which is a household name, but he did not finish elementary school: when Edison was in the first grade of elementary school, his academic performance was the bottom, his classmates laughed at him, his teachers looked down on him, and he was considered an imbecile, and he dropped out of school after only three months of study. His mother, who was a rural teacher, taught him to learn, read and write at home, ......Six years later, at the age of twelve, he had to sell newspapers on the train because of the difficulties of his family's life, and he was still experimenting on the train.

Once, when he almost burned the "laboratory", the conductor beat him so badly that he was deaf in one ear. Although he paid a heavy price for his experiments, he persevered and never gave up this ideal, and finally invented the automatic timer transmitter at the age of sixteen, which was a beautiful start, and then he invented more than 2,000 inventions one after another, which changed the value of his life dramatically.

If this case doesn't impress you, then I'll tell you another one: Li Bai, he was a famous poet in the Tang Dynasty, who wrote hundreds of poems in his lifetime, but he skipped school when he was a child: at that time, Li Bai read some esoteric and difficult articles all day long, and if he couldn't memorize them, he would be beaten by the teacher.

Li Bai felt that it was difficult to study, so he skipped school. Li Bai came to the stream alone and found an old woman sharpening an iron rod, Li Bai stepped forward and asked, "Old woman, what are you doing?"

The old woman looked at him and said, "Sharpen the needle." Li Bai asked puzzledly

So what's going to grind? The old woman said confidently: "As long as the kung fu is deep, the iron rod will be sharpened into a needle!"

Li Bai listened to it and thought: The old woman is so old, and she is determined to grind the iron rod into a needle, but I am afraid of going to school at a young age, so I am not as good as this old woman. From then on, Li Bai did not skip school, he studied hard, so that later, he wrote poems with peculiar imagination and bold style, and became a representative of romantic poets, and was praised as "poet immortal" by later generations.

Edison attended only three months of elementary school; Li Bai skipped school, in the eyes of the world, they are not good children, but they are very promising and are role models for the world. Edison, who was considered an imbecile by his teacher, became the king of invention; Li Bai, who skipped school because he was afraid of studying, was praised as a "poet immortal" by later generations, why is this? Is God favoring them?

No. Was it their luck? No.

So why exactly? It is their "acquired" efforts; worked the "day after tomorrow"; In the "day after tomorrow" to get rid of bad habits and deficiencies. Because as the saying goes:

Hard work pays off!
