1925 after graduating from junior high school, he was unable to enter senior high school because of his poor family, so he had to study accounting in the Chinese vocational school founded by Huang Yanpei in Shanghai, in order to find a job similar to accounting to support his family. In less than a year, due to the high cost of living, I was forced to drop out of school and go back to Jintan to help my father manage the grocery store. In the monotonous life of standing at the counter, he began to teach himself mathematics. When he returned to his hometown, he continued to study mathematics while working for his father in a grocery store with only a small facade. Recalling the time when he studied hard, his sister Hua Lianqing said, "Although it was winter, Luo Geng was still reading his math book at the checkout counter. When his nose ran down, he wiped it with his left hand and threw it aside. He didn't shake it off. He just stretched it out and his right hand kept writing ... "At that time, Luo Geng stood in front of the counter, waiting for customers to come, and helped his father do business, calculate abacus and keep accounts. As soon as the customer left, he buried himself in reading and solving math problems. Sometimes I am in a daze, forget to receive the customer, and even take the calculation result as the payment payable by the customer, which surprises the customer. Because similar inexplicable things often happen, after a long time, his neighbors treat him as a joke, and everyone has nicknamed him "Luo Daku". Whenever something happens that neglects customers, my father is angry and anxious, saying that he is too tired to read the "heavenly book" and wants to burn the book forcibly. When there is an argument, Hua always clings to the book.
Sir isaac newton isaac newton, an English physicist, mathematician, scientist and philosopher, was also a keen alchemist in Britain at that time. The law of gravitation and Newton's law of motion put forward by him in Mathematical Principles of Natural Philosophy published on July 5, 1687 are the cornerstones of classical mechanics. Newton and Leibniz also independently invented calculus. He always left more than 500,000 words of alchemy manuscripts and 6,543,800 words of theology manuscripts.
Newton was obsessed with scientific research to the point of obsession. It is said that Newton once boiled an egg. He works while reading. He stupidly threw a pocket watch into the pot. When the water boiled, he lifted the lid and realized that he had cooked the pocket watch as an egg by mistake. On another occasion, a visiting guest asked him to evaluate a prism. Newton was immediately attracted by this prism that can be used for scientific research and replied without hesitation: "This is priceless!" " "The guest saw Newton salivating at the prism and offered to sell it to him, deliberately asking a high price. Newton immediately bought it with joy. When the housekeeper learned that, she said angrily, "Well, you idiot, you just have to fold the price according to the weight of the cup!" " "
