Hua Luogeng devoted himself to self-study
When he was a child, Hua Luogeng helped his father with business, abacus and bookkeeping. At that time, Hua Luogeng stood in front of the counter, and as soon as the customer left, he buried himself in reading and worked out math problems. Sometimes I am fascinated, forget to receive customers, and even regard the result of calculation as the payment payable by customers, which makes customers startled. 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 an argument occurs, Hua Luogeng always clung to the book.
Hua Luogeng guessed books
Hua Luogeng, a famous mathematician, read books in a different way. He got a book, instead of reading it from beginning to end, he thought about it for a while, then closed his eyes and meditated. He guessed the layout of the book, and then opened the book after considering it. If the author's ideas were consistent with his own guess, he would stop reading. Hua Luogeng's guessing reading method not only saves reading time, but also cultivates his own thinking and imagination, so as not to make himself a slave to books.
Hua Luogeng was praised by the teacher.
His family was poor and he was determined to study hard. When I was in middle school, in a math class, the teacher gave the students a famous problem: "There is a number, three places and three places, and there is still 2;" 5 places with 5 numbers, with a surplus of 3; There are seven places in seven, and there is still 2 left. What is the number of this? " While other students were still thinking hard, Hua Luogeng quickly raised his hand and replied, "23!" The teacher was quite surprised and came over and asked, "How did you work it out?" Hua Luogeng slowly stated his thinking and calculus process: "I think this way: the number of three places is more than 2, and the number of seven places is more than 2. The answer to this question may be 3×7+2. I calculated again, 23 is divided by 5, so 23 is the number I want!" The teacher excitedly told the students: "Hua Luogeng's answer is correct, and the thinking of calculus is completely correct."
Hua Luogeng constantly simplifies the method of solving problems
Hua Luogeng was very fond of thinking when he was a child. After class, all his friends went out to play. He was still thinking about the teacher's questions, and sometimes he was so absorbed in thinking that his classmates told him not to listen. Over time, his classmates gave him a nickname, calling him "Luo nerd".
When the teacher opened Hua Luogeng's math homework, he found that many places had been altered, which was not neat at all. The teacher was very dissatisfied at first. Later, he found that Hua Luogeng was constantly improving and simplifying his own solutions. After his math talent was discovered by the teacher, he devoted himself to cultivating him. After graduating from junior high school, Hua Luogeng was admitted to Shanghai China Vocational School. After the last semester, his family couldn't afford 5 yuan's room and board, so he had to drop out of school, so he only had a junior high school diploma all his life. When he came home from school, he taught himself math while helping his father take care of the shop. When Hua Luogeng got into the math problem, it seemed like no one's business. He either forgot to receive the guests or drove them away. I just miscalculated the account and gave me too much change. My father was very angry. Once, he burned Hua Luogeng's math book, and Hua Luogeng was so distressed that he fainted to the ground.
Hua Luogeng advocates the method of reading from thin to thick
Hua Luogeng advocates that the first step of reading is "from thin to thick". That is to say, reading should be down-to-earth, and every concept and theorem should be thorough and clear. In this way, a thin book has become "thicker" because of a lot of content, which is "from thin to thick" After this step, there is a more important step, that is, on the basis of the first step, we can analyze and summarize, grasp the essence, grasp the whole, and achieve mastery. After such careful analysis, you will feel that there are not many things that should be remembered. This is a process of "from thick to thin" to really improve efficiency.
