Edison was curious about many things since he was a child, and he liked to try it himself until he understood the truth. When he grew up, he devoted himself to research and invention according to his interest in this field. He established a laboratory in New Jersey, and invented the electric light, telegraph, phonograph, film machine, magnetic mineral analyzer, crusher and so on for more than 2000 kinds of things in his life. Edison's strong research spirit made him make great contributions to the improvement of human lifestyle.
Now I'm going to tell you an interesting story about Edison's invention of electric light!
As early as 182 1, British scientists David and Faraday invented an electric lamp called an arc lamp. This kind of electric lamp uses carbon rods as filaments. Although it can emit light, it is dazzling, consumes a lot of electricity, has a short life and is not practical. So Edison secretly made up his mind: "Arc lamp is not practical, so I must invent an electric lamp with soft light so that every household can use it."
His experiment started with the material of the filament: the traditional carbon ribbon was used as the filament, and the filament broke when it was electrified. Ruthenium, chromium and other metals are used as filaments. After being electrified, it will burn out at one o'clock. Using platinum wire as filament is not ideal. In this way, Edison experimented with 1600 kinds of materials. After repeated trials and failures, many experts believe that the future of electric light is bleak. Some famous British experts even laughed at Edison's research.
Is "meaningless" Some reporters also reported: "Edison's ideal has become a bubble." Edison didn't flinch in the face of failure and everyone's cynicism. He understands that failure is the mother of success, and every failure means a step closer to success.
