Chapter 8 Chen Jingrun--Chapter 8 Building a Ladder

Lights at three o'clock in the morning In April 1981, Chen Jingrun returned to his long-lost alma mater, Xiamen University, to participate in the 60th anniversary celebration of Xiamen University.At this time, Chen Jingrun was very satisfied with his honor, and he was newly married. He looked very young and chic. When he first appeared on the rostrum of the Jiannan University Auditorium of Xiamen University and spoke on behalf of the alumni, thousands of representatives applauded thunderously. Facing the energetic and eloquent Chen Jingrun, almost everyone questioned in their hearts: Isn't it said that Chen Jingrun is weird, pedantic and stupid?Reality and imagination are different, how is this going on?Of course people believe what they see with their own eyes.This is the period when Chen Jingrun's health is at its best, and it is also the period when he launched a tenacious attack on Goldbach's conjecture (1+1).The short days of participating in the school celebration also left behind the footprints of his arduous journey.

Campus, eternal home.For Chen Jingrun, it is undoubtedly an unforgettable visit to Guzi by a wanderer from afar.Walking on the sunny path, every inch is full of lovesickness, picking up the lost youth, picking up the memory covered with weeds, and even picking up the ardent expectations of the alma mater and the unfailing heroic ambition. In terms of career, he started from Xiamen University.The campus remains the same.The endless thoughts turned into a phoenix tree as bright as the morning glow.The seaside building complex centered on the majestic Jiannan Auditorium is a magnificent group of sculptures composed of silver-gray granite, standing majestically on the stepped football stadium stands that can accommodate tens of thousands of people, majestic and magnificent.The group of buildings centered on Qunxian Tower stands quietly among the green trees. In front of the gate is the martial arts arena of the national hero Zheng Chenggong. But the majestic wind is still coming.The majestic kapok tree, the tall and straight palm, the tender brocade bamboo, the majestic Xiaoyelou, and the whispering acacia tree seem to weave the solemn intersection of history and reality.Being in it, Chen Jingrun felt that there was a majestic force like the sea urging him to speed up his pace to pick the most brilliant pearl of Goldbach's conjecture and conquer (1+1).

Number theory is beautiful.Laymen often think that it is a highly abstract game that is divorced from reality. Mr. Chen Shiingshen said a very insightful and profound sentence: "Number theory is the most important and profound applied mathematics in mathematics. Mathematicians do not have the opportunity to do it with real objects. Experiments, just experiment with numbers, and it turns out that there are many special properties between numbers, but the proof is sometimes very difficult, and some hypotheses are not sure whether they are correct, because they have not been fully proved." Regarding the last one of Goldbach's conjecture Difficulties (1+1), that's it.We must choose a brand-new method. To use Chen Jingrun's own metaphor, we must build a ladder to climb the cliff to pick the brightest star.

"Building a ladder", an ingenious project, restarted the long march of thousands of miles.Only Chen Jingrun, who is an expert, can appreciate the pain of painstaking efforts and the magnificence of going through all kinds of difficulties and obstacles.It is like a hazy and clear shadow, visible but intangible, exhilarating and suffering from elusive torment.Thinking of it, a kind of indescribable excitement and long-cherished wish that I am willing to work hard for it arises spontaneously from my heart. He was no longer the sickly Chen Jingrun who lived in the seven-square-meter Qinyezhai hut.Chen Jingrun was one of the most popular and respected guests when he returned to his alma mater to participate in the school celebration.According to the original opinion of the school, Chen Jingrun was to bring the newlywed You Kun back together.The hardworking and careful Chen Jingrun was worried that "the influence would be bad", so he politely declined the kindness of his alma mater, and traveled from Beijing to Xiamen by himself in a hard sleeper berth.A budget-minded mathematician saves the country a little money by avoiding the comfort of a soft berth.When I arrived at Xiamen University, I was arranged in a well-equipped and luxurious hotel-style guest house.He lives in the same room with his old friend, old fellow, and old classmate Academician Lin Qun.

Academician Lin Qun later fondly recalled this unforgettable day: Chen Jingrun seldom sleeps. Every night, after about twelve o'clock, he falls asleep. To my surprise, he falls asleep very quickly.Sometimes I lie down without taking off my shoes or clothes.Soon, there was a soft snore.He woke up at three o'clock in the morning. He was afraid of affecting my rest, so he moved very lightly. Then, he went to the living room lightly, turned on the light, and started to work at his desk.I woke up with a light sleepiness and asked him, "What are you going to do?" Seeing that I was woken up, Chen Jingrun was very sorry, apologized quickly, and said: "I'm really sorry, I'm sorry, I'll go to work for a while." After speaking, he went out.

Afterwards, Chen Jingrun told me that he has been doing the work of "building ladders" to challenge Goldbach's conjecture (1+1).In private, he also sighed and said: "The sieve method used to conquer (1+2) is no longer suitable for conquering (1+1). We must find another way. Where is the way? Maybe there is no way at all." , the only way to climb up is by taking a ladder." The light at three o'clock in the morning, like a faint hope, dotted the campus known as "the strongest in the south".The night was long and quiet.Nanputuo, the first temple in southern Fujian, is close at hand. Devoted men and women have already fallen asleep, and the colorful pavilions and pavilions have also quietly melted into the thick night.The sea, which was noisy all day, also fell into a dream.Only Chen Jingrun, with all his thoughts, used numbers as bricks and stones to persistently pave a road to the future.

The school celebration is an extremely rare class reunion, teacher-student reunion, classmate love, brotherhood, how many times, meet in a dream.Shake hands, hug, and greet each other, and then, look at each other carefully, are you looking for the traces of the boy who was the classmate of Qia back then, or savoring the vicissitudes of life from every wrinkle and every gray hair of the other party?Time is too ruthless, in the past twenty or thirty years, the acacia trees beside the road are still luxuriant, but the long river of time has cruelly swept away the most precious and dazzling years in the lives of these students.During the reunion with his classmates, Chen Jingrun discovered that the four classmates in the same class were all alive, and the others had achieved certain achievements in college.The classmates he knew were also impatient. They didn't even have time to say hello, so they let go and said goodbye to this helpless and nostalgic world forever without saying a word.After gatherings, when alone, Chen Jingrun felt more and more the brevity of the journey of life.From 1966 when he first captured Goldbach's conjecture (1+2) to 1973 to further perfect it, it took 8 years, as long as the War of Resistance Against Japan; from 1973 to now, another 8 years have passed Over time, he made a significant improvement on his own result, advancing the smallest prime number from the original 80 to 16, which was highly praised by domestic and foreign peer scholars, and made valuable contributions in other fields of number theory .However, in 2016, with a flick of a finger, the heart-wrenching long-cherished wish of conquering (1+1) still has not made substantial progress.

The more he thought about it, the more he couldn't sleep. He wished he could use one day as two.Xiamen University is full of outstanding people, and the shaded campus paths can pick up a lost legend just by bending over.The green grass, the spring sun is like a bath.The respected school principal, Mr. Tan Kah Kee, stood motionless on the side of the playground with a cane in his hand. Could it be that he was too tired, and spent his entire life worrying about building this extremely beautiful campus.He is immortal, his life is not only turned into a bronze statue, but also into the smiles of thousands of students, into the blood of countless Chinese heroes, into the infinite spring of this eternal home. Mr. Lu Xun, who "turned his eyebrows coldly at thousands of men, and bowed his head willingly as an ox", was leaning on a corner of the grass in a long robe and with a short mustache; his gaze was still so cold and majestic. The stone carvings have also become the unyielding backbones of the people walking out of here, and have turned into iron bones that can make all the flatterers, informers and all ugly people in the world terrified.The vicissitudes of life are like the sea, all in my heart.Chen Jingrun's footsteps seemed to be on the strings of life, and every step aroused strong shock and echo in his heart.

At three o'clock in the morning, the room where Chen Jingrun lived was lit up.Silently.Outside the window, there are fruit-bearing longan trees, brewing a dream of a bumper harvest in autumn.What did Chen Jingrun, who was working at his desk, figured out?have no idea.He only left this long-lasting story. The Birth of Four Popular Science Books Science is tragic.It also requires the spirit of succession. There are four books in front of us. They are quite different from the thesis written by Chen Jingrun, but are lively and easy-to-understand popular books. This is the most precious gift Chen Jingrun left to the young people of the country.

One is "Goldbach's Conjecture", published by Heilongjiang Education Press in May 1986; the second is "Interesting Mathematics Talk", published by Liaoning Education Press in 1987; the third is "Introduction to Combinatorics", Tianjin Science and Technology Press published in July 1988; the fourth is "Elementary Number Theory", published by Science Press in September 1988.The four books, just like the cute little red sails of four leaves, guide thousands of young people across the country to cruise in a light boat in the ocean of mathematics. In the tense days of tenacious impact (1+1), Chen Jingrun wrote these popular science books for teenagers, which seemed not to be closely related to the main direction of attack. The direct reason was that he was invited to give lectures to primary and middle school students again and again and received letters from many teenagers across the country .Chen Jingrun is born with a childlike taste, he loves children very much. After 1985, his physical condition was not very good.Comrade Fang Yi, who was the director of the State Science and Technology Commission at the time, found that Chen Jingrun's expression was a bit unnatural during a chance contact with Chen Jingrun.The illness began to torment him, but as soon as he was among the children, he felt full of energy. His time was very precious, and he could not meet the requirements of more schools, so he began to use his "free time" to write these books suitable for teenagers to read Popular science books about mathematics will help more children love and understand mathematics and become successors in the Chinese mathematics field.

Reading the four special books left by this mathematician, you can feel Chen Jingrun's warm and moving smile almost everywhere between the lines, and the kind and harmonious soft-spoken with a strong Fujian accent.The topic selection and content of the four books are obviously well thought out and carefully arranged.The first book is "Goldbach's Conjecture", which is the pearl of mathematics and an everlasting banner. It guides Chen Jingrun to struggle for it all his life.Back then, it was Professor Shen Yuan who inadvertently sowed a strange seed in Chen Jingrun's heart. As a result, not only changed Chen Jingrun's life, but also changed the history of mathematics in China.Today, Chen Jingrun is also sowing seeds, spreading hope and longing in the hearts of hundreds of millions of young people.Opening this book, Chen Jingrun vividly outlines Goldbach's conjecture, a worldwide proposition of the century, in simple and easy-to-understand language. The "noble peony" also shines with the vitality and charm of the green field.Persisting research, long-term attack can not be overcome, for the problem of impact (1+1), Chen Jingrun tried to use popular language to explain to people: "The closer to the limit, the greater the difficulty. Although many mathematicians around the world are working hard to extract This laurels, but using the traditional mathematical method to prove (1+1) is no longer feasible, the key is to find a brand new method, this is like, it is impossible to observe alien planets with naked eyes, it is possible to do it with electronic telescopes, but so far No one has found a new method similar to the electronic telescope..." Could it be that Chen Jingrun, who is not lacking in foresight, also deeply felt after a long battle that to overcome this last difficulty, he not only needs to continue to work hard, but also needs hundreds of millions of people to work hard? Will the latecomers go to the front line?This rare booklet is undoubtedly the seed of spring, which has been sown in the hearts of countless teenagers who love mathematics. One day, people will see a fruitful harvest. Interest is the guide to getting started and often the mother of success.To learn a subject well, just relying on studying hard without the strange addition of interest is indeed a torture.Interest itself is a complex psychological phenomenon, which has a certain relationship with people's natural endowments.Some people love literature, are good at image thinking, and have a special sense of beauty in life; there are also people who love mathematics, physics and chemistry, absorbing the charm of natural science fields tirelessly and with relish, and have a natural affinity for logical thinking. Joy.They are all extremely precious prerequisites and foundations for learning a certain subject well and further studying a certain subject.Chen Jingrun, who is proficient in mathematics, certainly understands the magic and mystery of interest.His fondness for mathematics comes from nature on the one hand, and more importantly, interest can be induced and cultivated.It is the inspiration, training and education of many mathematics teachers that shaped the legendary Chen Jingrun.Based on his own life path and experience in studying mathematics, he paid special attention to cultivating young people's interest in mathematics. The great world, viewed from a mathematical perspective, can be said to be a mathematical world.Abstract mathematical symbols can also weave earth-shattering symphonic poems and serenades with profound artistic conception.Numbers are revealing, expressing, and interpreting countless charming fairy tales and myths in our infinite world.When people are amazed at the miracle of accurate positioning of satellites and the successful docking of spaceships in the aerospace world, experts who are familiar with number theory tell people that these are just a few skits in the mathematical drama.The breadth and depth of mathematics are unparalleled, and at the same time, it is infinitely interesting.Chen Jingrun once did a math problem for his son Huanhuan, from 1 to 10, what is the number?This is an interesting math problem. It is easy to get the result by adding the two ends."Interesting Mathematics Talks" written by Chen Jingrun starts from the interests that people are willing to accept, so that young people can enjoy the world of mathematics happily.This book is full of flashes of wisdom and innocent laughter everywhere.Books are like people, words are the voice of the heart, and the same is true for mathematics books. Do you want to understand Chen Jingrun's childlike innocence?Do you want to know Chen Jingrun's extraordinary wisdom?It is very interesting to read this easy-to-understand and interesting book once in a while. "Introduction to Combinatorial Mathematics" and "Elementary Number Theory" are both books that introduce the introduction to mathematics. They are well-organized, persuasive, and easy to understand, and are also excellent among science and technology books for teenagers.Mathematics is a basic subject in the natural sciences, and its popularity and level are closely related to the prospects of my country's four modernizations.Foresighted educators and experts have repeatedly appealed to those knowledgeable scholars to write popular science books for young people, and to understand this grand foundation project from a cross-century perspective. Chen Jingrun's actions are just in line with this trend of the times And a model of vision. Since Goldbach proposed the "Goldbach Conjecture" in a letter to Euler in 1742, more than 200 years have passed. Generations of mathematicians have devoted all their enthusiasm and wisdom to accumulating countless valuable materials. , and finally built an incomparably brilliant mathematical palace.Therefore, in a certain sense, mathematics can be continuously enriched, improved, and reached a relatively perfect and mature state only by the overall efforts of human beings and the continuous efforts of people from generation to generation.Young people in their prime are the future of mathematics.When Chen Jingrun, who was suffering from illness, was enduring the pain and torture and trekking endlessly, perhaps, he had already read the tomorrow of mathematics from the eyes of teenagers who were still immature but shining with desire and pursuit. In an era when science and technology update knowledge and technology with the magic of rapid changes, the contents of these four popular science books written by Chen Jingrun targeting teenagers may not be very new as time goes by, but there is a lot of meaning between the lines. Chen Jingrun's rigorous attitude of emphasizing the basics and basic skills, and his sincere love for the future of the motherland despite serious illnesses will last forever. The four thin booklets also contain a heavy weight. "I'm building a ladder" Today, people already understand what happened at the Chinese Academy of Sciences: it happened before the "Cultural Revolution". Once, a new cadre was transferred, and Chen Jingrun followed his colleagues from the Institute of Mathematics to visit politely.The new cadres were very polite, busy handing cigarettes and water, and greeting everyone one by one with a big smile.At this time, someone suddenly found that Chen Jingrun was among them, as if he had been greatly insulted, he asked sharply, "Chen Jingrun, what are you doing here?" Chen Jingrun was not prepared, let alone expected that this person would be so impolite He treated him rudely and rudely, and didn't know how to answer for a moment. This person who regarded himself as "noble" actually yelled: "Chen Jingrun, get out!" residence.Even his most basic personality and human dignity are often brutally deprived by those "leftists".However, what is amazing is that once he entered the kingdom of mathematics, with superhuman perseverance, he abandoned these extremely unfair and even extremely inhuman treatment in the world, and devoted himself to tackling key problems close to hand-to-hand combat. For a true scientist, his personality and dignity are the real mountains and seas, the monuments that stand in people's hearts, and those who rely on power or cling to power to fly domineeringly are nothing but dung.The ancients said: Honor and disgrace do not surprise.Reaching such a state of life is not an ordinary person. After becoming famous, Chen Jingrun’s biggest wish is to climb to the peak of Goldbach’s conjecture and pick the bright pearl of (1+1). Mr. Min Sihe passed away unfortunately, and Chen Jingrun cried bitterly. He was sad for losing a mathematician who really understood him , In private, he once told his friends that Mr. Min passed away, who will review his thesis manuscript on conquering (1+1) in the future?When he was extremely sad, he once said sadly, I will not do (1+1) anymore.The simple Chen Jingrun is worried that his bosom friend will be cut off. No one in the world can really understand him, understand him, and no one can understand his scientific research papers. With the collapse of the "Gang of Four" and drastic changes in the national situation, Chen Jingrun's dark clouds also dissipated as he watched the sunny and charming spring.When crowns of laurels and dazzling honors came one after another, Chen Jingrun, who was in adversity, was not obsessed with fame. His sincere heart was still determined to stay in the loneliness that challenged Goldbach's conjecture. on the ground. All kinds of pressure brought about by cold reception, discrimination, and adversity in the world can trap and kill the created life. However, for those with extraordinary ambitions, they may also inspire greater courage to fight for the future and tomorrow.This is the reason why "adversity is a rare school" praised by foreign scholars.Carols, flowers, applause, and good times can also bring blind complacency, induce vanity, and make those who strive intoxicated, forgetting their sacred responsibilities and missions.It is not uncommon for heroes to be overwhelmed by the hymns of victory. We search for Chen Jingrun's footsteps in flowers and praises again and again.Chen Jingrun, who has a perfect career and family, has not repeated the tragedies of many heroes. He is still carrying his luggage as always, and trekking hard on the road to the peak of Goldbach's conjecture. Childlike innocence.It is impossible to interview Chen Jingrun about his impact (1+1).He has been rigorous in scientific research all his life.The esoteric mathematical formulas and cumbersome reasoning process are incomprehensible to laymen, and he will not introduce them.Only he can appreciate the hardships during the impact, and he is not good at words, let alone how to express them.Admiring the reporter who is skilled in the art of interviewing, he finally discovered that Huanhuan is not only an innocent and cute child, but also an "important person" who understands certain "military situations". Huanhuan was very polite since he was a child, and he was enthusiastic and novel to the reporters who came to interview. When the reporter asked about Chen Jingrun's situation, some "insider stories" he revealed were very interesting: "Every day, my dad always stays up late, and asks him what he is busy with. He says, doing homework. That is, doing math problems. He often stays up until three or four o'clock the next day. Once, My mother got angry and quarreled with my father, and my father went to sleep slowly." Speaking of this, Huanhuan laughed, and the reporter also laughed. You Kun, who was born in the military, did not reveal the "secret" easily. Seeing that his son had missed something, he explained: "Mr. often forgets about his own health when he is working. I used to have a bad temper and willfulness. I seldom get angry, and I understand your husband's feelings. Sometimes, I can't help it and get angry, but as long as I get angry, my husband will listen to me." As soon as You Kun finished speaking, Chen Jingrun was also amused, He was in a hurry to smooth things over. "I listen to you, I listen to you." Then bursts of hearty laughter erupted in the room. Chen Jingrun vividly compared the peripheral work of overcoming Goldbach's conjecture (1+1) to "building a ladder". How easy is it to "build a ladder"?Only by building the ladder of life well can it be possible to build the ladder of scientific research. He is unyielding. In 1985, Chen Jingrun became seriously ill. At the beginning, he was hospitalized in the China-Japan Friendship Hospital.He has been sickly since he was a child, and various diseases followed him like a shadow. Perhaps, he has been sick for a long time, and it is commonplace, so he doesn't take it seriously.He didn't look like he was hospitalized. He took books and various materials with him, and the ward became a studio. Day and night, he was still calculating and reasoning non-stop, often working until four or five o'clock in the morning the next day.To the surprise of many doctors and nurses, Chen Jingrun, who almost slept all night, was still in good spirits the next morning.Sometimes, he was worried that the doctor would come to make ward rounds, so he "repeated the old trick" and turned on the flashlight, hiding under the covers and reading.At the cost of burning the fire of his own life, he hopes to build a ladder leading to the beautiful peak. Will he think of Du Fu's tragic poem about Zhuge Liang? "Death before leaving the teacher will make the hero burst into tears." In the dictionary of Chen Jingrun's life, he hardly mentioned the word death that terrifies ordinary people.He has endured too much suffering, and he has already experienced the threat of death, so he takes all this lightly.He is a bamboo that "holds on to the green hills and does not let go". No matter the wind and rain, no matter the severe frost and snow, I will stand still.His extraordinary tenacity and the spirit of carrying forward the power of life to the extreme state have set up the most brilliant banner of life for people! In the long years of "building the ladder", how many questions Chen Jingrun has done is really hard to count.In the past, his draft papers were packed in sacks, but later they were placed in piles in the study, and many of them were still in the office.He has passed away for more than a year. So far, when you walk into the Institute of Mathematics, you can find Chen Jingrun's draft paper on the desks of former colleagues, or in the cabinets of the office at any time.The handwriting is as engraved as engraved, as if it was left yesterday, imprinting the deep and shallow footprints of this mathematics giant, and also imprinting memories and faint regrets that cannot be let go. In the last few years of Chen Jingrun's life, he was still unremittingly doing the work of "building ladders".His last thesis was "About Goldbach's Problem" co-authored with Mr. Wang Tianze. It has been haunted by dreams for decades, and the dazzling brilliance of the mathematical crown has been illuminating his entire voyage of life. During Chen Jingrun's serious illness, he couldn't open his eyes and needed a massage for more than an hour to open them a little bit. The sensible Huanhuan massaged Chen Jingrun since he was a child, and he developed massage skills that surprised even professional doctors.However, his mind is always clear. He is lying on the sickbed, and together with his graduate students, he is still unremittingly exploring the climbing road. Exhausted all the brilliance of life, searching all over the mountains and mountains of mathematics, although Chen Jingrun did not find this mysterious path leading to the peak of Goldbach's conjecture (1+1), nor did he build the towering sky to the sky. "Ladder", but the lofty spirit radiated by his life trajectory has weaved a ladder enough for the latecomers to continue to climb.The ladder of life should be walked like Chen Jingrun, in order to enter the glorious tomorrow. Chen Jingrun is crying A man does not flick his tears easily.Chen Jingrun does not shed tears easily. When he was a teenager, he was introverted and stubborn, with a weak body. Whenever he was bullied at school, or even beaten until his nose was bruised and his face was swollen, he never shed tears, let alone beg for mercy. The young man was studying at Xiamen University, living in poverty and suffering from tuberculosis. Facing heavy homework, he was self-reliant and tenacious to survive. During the years of suffering, he was wrongly pulled out of the "white flag" and sent to other places to wash bottles for no reason. He was coldly stared at, but he did not shed tears; , he did not shed tears. A person needs a little spirit. In Chen Jingrun's blood, there flows the unyielding temperament of the descendants of the Chinese nation who are not willing to give in.He didn't have the slightest bit of servility and obsequiousness. Chen Jingrun, who had a great reputation, cried on a special occasion, and cried so sadly. In 1984, an American mathematician visited China and offered to visit Chen Jingrun.Chen Jingrun received him at the Institute of Mathematics.At that time, it was widely rumored that the Soviets had conquered Goldbach's conjecture (1+1). Chen Jingrun was very sad when he got the news.During the symposium, when talking about this issue, the American mathematician told him: This is a misinformation.The guest politely and humbly explained: "This is impossible. If you can calculate (1+1) in the world, you should be the first one." It was said that Chen Jingrun's heart was a little calmer. Just like a mountaineering competition, when people learned that Chen Jingrun had calculated (1+2), ambitious mathematicians all over the world set their progress at (1+1).Sprinting to the top is the glory and pride of a nation and country.Chen Jingrun, who is already far ahead in this field, is willing to easily give up this honor to others. Since the early 1970s, Chen Jingrun has made a determined effort to do his best to draw a successful conclusion to this cross-century battle to overcome Goldbach's conjecture.In the blink of an eye, ten years have passed, and more than three thousand days and nights have been silently melted into the trek without a trace.Where is the road? Where is the "ladder"?Looking back on the past, inexplicable melancholy and sentimental, involuntarily surfaced in my heart. It is a kind of luck and consolation to sow, sow, harvest, follow the normal rules of labor, and get the desired results after hard work.The profound and tragic aspect of this battle of the century to overcome (1+1) lies in the fact that it surpasses the conventional laws of general labor, and does not use hard work as the criterion for measuring gains.The cruelty of science is shown here in such a cold and ruthless way, one hundred percent pay, but the harvest is often pale and helpless zero. Will there be a miracle of "the mountains and rivers are all doubtful and there is no way out, and the willows are dark and the flowers are bright and another village"?Chen Jingrun has looked forward to it countless times, from winter to spring, from night to dawn, when disappointment is like daily mediocrity and almost wears out the heart, the strongest man will also feel that the years are wasted. Deep sadness. Occasionally, dark shadows of despair would strike suddenly, and the sun and the moon would be dark.Just like on the way to climb Mount Everest, there was a sudden storm. In a blink of an eye, the exquisitely carved glaciers turned into fangs in the devil's bloody mouth, and the sky collapsed, as if to push the world into a dark abyss.In a broad and philosophical sense, failure is the mother of success.But for individuals and a specific battle, failure does not shine with any charming halo, but a black disaster.Shock (1+1) is not only a arduous exploration in science, but also a struggle of the soul, repeated contests of personality and will.All winners are strong, but not all strong are qualified to enjoy the joy of victory. Chen Jingrun is very clear about his environment and status.He is not the kind of person who quits in a hurry. After he has achieved brilliance, he is not like those players who have won world championship medals in the sports world.The life coordinate he set for himself is to overcome Goldbach's conjecture (1+1), which is the real "world champion". For this reason, he consciously broke the boat and cut off his retreat.As long as there is still one day in life, he will go on unremittingly.This kind of "stupid" energy is inherent and cannot be changed. For many years, mathematicians from all over the world have been closely watching China and the amazing Chen Jingrun.For a long time, the blue-eyed and red-haired foreigners couldn't understand how the Chinese, with a pen and a few sacks of draft paper, were so capable of winning the attention of the world (1+2).And Chen Jingrun's eyes widened, watching the dynamics of the world's mathematics community.The Soviet Union, the United States, France, Germany, and even Japan, which is also in the East, have a group of world-class mathematicians. There are as many strong opponents as there are forests. In the arena, it is really difficult to determine who will win.The world is so big, I don't know when a dark horse will suddenly appear from an unknown place, which will make all the mathematics masters stunned, and quickly pick off the brightest jewel in the crown. This legendary This is nothing new in the history of science. It must be done quickly, ahead of the foreigners, ahead of the journey of life, a strong sense of urgency struck Chen Jingrun's heartstrings again and again.He didn't dare to slack off, and he couldn't slack off, and he was used to using one day as two or even three days. In the summer of 1984, a German mathematician visited China, and he found Chen Jingrun admiringly.They are all experts, and they talked very speculatively.Chen Jingrun's English level is good, and there is no need for an interpreter. The two sides can talk calmly. They discussed solving Goldbach's conjecture together. While talking, Chen Jingrun cried, and cried very sadly.The visiting foreign friends did not feel sudden and unexpected, but just sat quietly, as if they were savoring the state of mind of this oriental mathematician; as if they were silently sharing the anxiety and worries of this mathematician.Li Xiaoning, Chen Jingrun's assistant, was also sitting at the side. He didn't try to persuade him, and he didn't know how to persuade this mathematician of the senior generation.This was the first time he saw Chen Jingrun shed tears and heard Chen Jingrun's heartbreaking cry.Do you feel sad because you have made no progress after ten years of hard work, or are you ashamed of the high hopes of the motherland and the people, and feel guilty?Afterwards, people did not ask Chen Jingrun, and they felt that there was no need to inquire about this matter.People just noticed that Chen Jingrun hurriedly walked into the reference room called "the second and a half floors" of the Institute of Mathematics as before. , people seldom go to sit on it.It's just that people already know his habits deeply, and once they get into the pile of materials, they are reluctant to come out.When it was time to get off work, the comrades on duty had to search carefully, so as not to repeat the incident of locking Chen Jingrun in the reference room for the night. He is speeding up and using the last strength of his life to meet the sacred day that the world's mathematicians have been looking forward to for more than two centuries.After fighting hard for a long time, he was exhausted and felt unwell.When it comes to winter, I am particularly afraid of the cold. I feel the icy cold from my spine, and my vision begins to decline. Only the heart that does not die is still hot. People never expected that on April 27, 1984, when Chen Jingrun was crossing the road, he was knocked down by an oncoming bicycle and landed on the back of his head, resulting in an accidental serious injury.To make matters worse, Chen Jingrun, who was not in good health, suffered almost fatal injuries.When he came out of the hospital, his pale face sometimes had a melancholic blue-gray, and soon he finally induced Parkinson's syndrome.Surprisingly, Chen Jingrun seldom shed tears after suffering from a terminal illness, and he was never heard crying.A man's tears are gold, and occasionally they come out of the eyes, which makes people thrilling. "It's not free to be emotional when something happens, and it's hard to get melancholy once in a while." Tears shed on the battlefield, pouring out his true feelings.The journey of scientific research is tragic and desolate.
