? Lippmann was originally a poor painter, and all the painting tools he used were worn out, but he didn't give up his artistic pursuit.
? One day, when he was absorbed in drawing a sketch, he found that the picture needed to be revised. He searched for his only eraser in the messy studio. He searched for it for a long time before he found it, and as a result, he lost the pencil point again.
? He found this, lost that, and finally found it all, which took a lot of time. In a fit of pique, Lippmann decided to connect the rubber head with the pencil, which would be much more convenient to use. But how to fix this naughty rubber head firmly on the pencil head? To this end, he thought of various ways, and finally, he came up with a good way: wrap the rubber head and pencil head with a small piece of thin iron sheet.
? This is the pencil with eraser that people use today.
? Soon, a company bought his patent for a huge sum of 550 thousand dollars. Lippmann also changed from a poor painter to an inventor and a monopoly.
? We should learn from lippman, be conscientious in life, be brave in exploration, try boldly, observe carefully and make unremitting efforts, and maybe we will become the next inventor. At the same time, if you set a goal, you should do it wholeheartedly. I believe there will be a good result in the end.
