More than 20 years ago, a reportage "Goldbach Conjecture", which caused a sensation in China, made a mathematical wizard a household name overnight. The deeds of this man even promoted the early arrival of a great era of respecting science, knowledge and talents to a certain extent. His name is Chen Jingrun.
Not talkative, he used to be an "ugly duckling". Usually, a person who is born deaf will have a particularly keen eye, a person who is born blind will have a very keen hearing, and an "ugly duckling" who has been neglected and unpopular since childhood will often meditate involuntarily or in all kinds of helplessness, explore things, learn from things, and find a suitable position in the world to develop his potential. You can say that this is forced out, but such "forced" will often "force" many great people. Like Chen Jingrun in childhood. Chen Jingrun was born in 1933, the family of a post office clerk. He just turned 4 when War of Resistance against Japanese Aggression started. Soon, the wolf smoke of the Japanese invaders burned to his hometown of Fujian, and the whole family fled into the mountains, and the children entered the mountain school. Fathers are too busy making a living to take care of their children's education; My mother is an old housewife and has worked hard all her life. She had 65,438+02 children, but only six survived. Chen Jingrun is the third, with brothers and sisters, and younger brothers and sisters. There is an old saying in China that "the little boy in the middle has a flat head". He is thin and weak. It is conceivable that he is dissatisfied with his parents and is not good for his brothers and sisters. At school, he is no better, because he is silent and doesn't like to talk. Unpopular, bullied, and often beaten and scolded for no reason. It happened that he was stubborn by nature and never begged for forgiveness in order to improve his situation. Unconsciously, he formed a self-enclosed introverted personality. People always need to communicate, especially children. A gifted child, faced with this dilemma, may become a perverse Woodenhead, but Chen Jingrun didn't. His natural passion for numbers and symbols made him forget the hardships and troubles of life and concentrate on the pagoda of knowledge. He wants to find a breakthrough and find happiness in life there. Teaching students in accordance with their aptitude is to create a space for each student to fully develop according to their own characteristics through certain educational and teaching methods and means.
Chen Jingrun Jr. teaches students in accordance with their aptitude.
Fortunately, this pupil has met a professor all his life, but he is still a child. In addition to burying your head in reading, you need face-to-face and hands-on guidance. After all, what can bring the greatest, most direct and vivid inspiration and joy to children is the kind of communication and contact between people, which can make people's hearts glow with brilliant sparks. Fortunately, when the family returned to Fuzhou, Chen Jingrun met Shen Yuan, a famous teacher who claimed to be a lifelong beneficiary.
Shen Yuan is a famous aerodynamicist, an aviation engineering educator and a leading figure in China's aviation industry. He graduated from the University of London, Imperial College London, and was the head of the aviation department in Tsinghua University. He went back to Fuzhou from 1948 to take care of his family. During the war, he had to stay in his alma mater Huaying Middle School to teach temporarily, and Chen Jingrun was the student in his class.
Professors in famous universities have their own unique skills in teaching young children. According to the age and psychological characteristics of the teaching object, Shen Yuan often introduces the explanation of the topic in a simple way by telling stories, which can easily lure those young children into the superb scientific world and arouse their great enthusiasm for science and learning. For example, on this day, Professor Shen Yuan told the students a story about Goldbach's conjecture with great interest.
The "pearl" left by the teacher illuminates the future of juvenile struggle.
"We all know that in positive integers, 2, 4, 6, 8, 10 ... these numbers that can be divisible by 2 are called even numbers; 1, 3,5,7,9, etc. It is called odd number. There is also a number that can only be divisible by 1 and itself, but not by other integers. This number is called a prime number. "
As usual, the whole classroom can even hear the sound of an embroidery needle falling to the ground in silence, only Professor Shen's calm and rich voice echoes.
"More than two hundred years ago, a German middle school teacher named Goldbach found that every even number not less than 6 is the sum of two prime numbers. For example, 6 = 3+3, 12 = 5+7,18 = 7+1,24 = 1 1+ 13 ...
"However, guess is guess after all. Without rigorous scientific argumentation, it can only be a guess forever. " Now it's Chen Jingrun Jr.' s turn to make a commotion. But in my heart.
How to scientifically demonstrate? Can I grow up? He thought. Later, Goldbach wrote a letter to the famous mathematician Euler at that time. Euler received this letter with great enthusiasm and threw himself into this interesting debate almost immediately. Unfortunately, however, despite Euler's painstaking efforts, he failed to prove this conjecture until his death. Since then, Goldbach conjecture has become a world-famous mathematical problem. For more than 200 years, it has made many talented scholars and heroes in the field of mathematics advance wave after wave and compete with each other. The classroom is boiling, and the children's curiosity and imagination are mobilized.
"Mathematics is the queen of natural science, and the crown on the queen's head is number theory. The Goldbach conjecture I just mentioned is a dazzling pearl in the queen's crown! "
Shen Yuan finished the story about Goldbach's conjecture in one go. The students talked about it in succession, and it was very lively, but the introverted Chen Jingrun didn't say a word, and the whole person was "crazy". This quiet, quiet and thoughtful child was completely brought into a colorful magical world by Shen Yuan's story. Although other students are amazed, when this admiration is over, it will be over, but he secretly tells himself over and over again:
"Are you okay? Can you take off this jewel in the crown of mathematics? "
One is a university professor and the other is a child with yellow mouth. Although there is no communication or even conversation between them in the strict sense, this class is really a heart-to-heart meeting, because it laid the foundation for Chen Jingrun Jr.' s beautiful ideal, a goal to work hard for, and made him willing to fight for it all his life! Many years later, Chen Jingrun graduated from Xiamen University. A few years later, he was appreciated by the famous mathematician Hua and transferred to the Institute of Mathematics of China Academy of Sciences. Since then, under the leadership of China, Chen Jingrun devoted himself to the long-term and outstanding demonstration of Goldbach's conjecture day and night.
1966, a dazzling new star rose in the field of mathematics in China. Chen Jingrun told the world in the China Science Bulletin that he proved it (1+2)!
1In February, 973, Chen Jingrun, who rose from the catastrophe of the Cultural Revolution, revised (1+2) the certificate again. A theorem it proved shocked the international mathematics community and was named "Chen Theorem". I don't know if Professor Shen Yuan can still remember what he said to these children in those years, but Chen Jingrun always remembers that he has been so clear all his life.
