On genius lies in diligence.
Edison was a great electrician and inventor. He was born in Mylan, Ohio, USA. He has worked in his father's timber factory since he was a child. Because of his poor family, he only studied at school for three months in his life. But he loved science since he was a child, taught himself hard and was addicted to invention and creation. The number of officially registered inventions reached 1328, and he was called the king of inventions in the world. Students, you know why Edison can invent so many things. The secret is that you are not only clever, but also hard-working, which is why you have made such great achievements. After reading the following story about Edison, you will understand how important diligence is.

Edison invented many inventions when he grew up. Edison began to study electric light in his early twenties, which lasted for 10 years. He chose thousands of different substances, such as bamboo wool, graphite, tantalum and so on. As a filament material for experiments, this is well known. Once he and his assistants worked for five days and five nights in a row. Edison failed many times when he invented the electric light bulb. When he used 1000 materials as filament, his assistant said to him, "You failed 1000 times, and your success became slim. Give up! " But Edison said, "So far, my harvest is not bad. At least I found that there are more than 1000 materials that cannot be used as filaments. " After more than 6,000 experiments, he finally succeeded. 1879 Edison made incandescent filament with carbon filament and lit it for 40 hours. Because the surface of carbon wire is porous and fragile, its strength is very low. It was soon replaced by tungsten wire.

In fact, Edison was able to invent so many inventions, not only because of his clever mind, but also because of his persistent experiments and never giving up. He once said, "Invention is one percent inspiration and ninety-nine percent perspiration."

Yes, even if you have a smart mind, even if you have superb skills, you won't succeed without hard work. Students, after listening to Edison's story, did you get some inspiration?
