How much did South Ren Dong, the father of Eye of the Sky, contribute to China?

Speaking of astronomers in China, who do you think of, Zhang Heng, who created the seismograph and the armillary sphere, Zu Chongzhi, who made the value of pi accurate to the seventh decimal place, or Guo Shoujing, who wrote astronomical masterpieces such as Pushing Step and Li Cheng?

It is true that they are all the brightest stars in the history of astronomy in China, but they are separated by thousands of years, and many of their deeds and contributions cannot be clearly verified. As usual, after the founding of New China, at the beginning of 2 1 century, a comparable figure-Nan appeared in China.

At first glance, it seems to be the overbearing president in some novel. In fact, he is an out-and-out modern astronomer with outstanding achievements. He is known as the father of the "Eye of the Sky" and is worshipped by many Chinese and foreign scholars and students. How important is "Eye of the Sky" to China, and how great is the contribution of South China? Many people brush the word "eye of the sky" more quickly in news, newspapers and even social media such as Tik Tok and Aauto, but it is not very clear what it is. In fact, the essence of the "eye of the sky" is very simple, that is, an astronomical telescope (also known as FAST) used to explore the universe and the sky.

But compared with other telescopes, it is larger (with a total area of 250,000 square meters, equivalent to 30 standard football fields) and has more functions. It is the largest radio telescope with single aperture and the most flexible response in the world, which can locate cosmic celestial bodies and radar signals with the fastest speed and maximum accuracy. Even if the celestial body is so small that other radio telescopes need precise coordinates to capture it, the observation and positioning only need 1 minute, which is eight minutes faster than the world standard.

In addition, China discovered 102 certified pulsars with the help of the super-high flexibility of "Eye of the Sky" (its rotation period is stable, like a cosmic lighthouse, which is very helpful for the development of the space industry), which improved the timing accuracy of the existing pulsars in the world by 50 times.

Even compared with Arecibo's 300-meter-caliber radio telescope, which was rated as one of the top ten heroes in the 20th century, China's "Eye of the Sky" is not inferior, and its flexibility can reach 2.25 times that of Arecibo.

It can be said that with the "Eye of the Sky", even chatting quietly in outer space will be captured, which plays a great role in preventing illegal submission and capturing monitoring and positioning. It can not only be used to explore the unknown secrets in The Mystery of the Universe, but also promote the rapid development of China's space engineering, and it can also radiate to all aspects of daily life and improve the existing technical level, which is the most powerful testimony that China's astronomy industry is leading the world.

The biggest hero behind this huge project is South Ren Dong. 1994 put forward the "Eye of the Sky Project" for the first time, and personally participated in the later site selection and design work.

For this reason, he trekked in the mountains in the southwest of China, spent 12 years, compared more than 4,300 days and nights with 1000 depressions, and finally chose the address of the so-called "Eye of the Sky"-karst potholes in Pingtang County, Guizhou Province.

It's easier said than done. Just to choose a site, his hair was covered with frost and snow, and his face was covered with ravines. It was he who did not fear the cold and heat, did not give up on-the-spot investigation and evidence collection day and night, and listed all kinds of data analysis, so that the project was approved by the state in 2007 and officially started. This year, he once turned 60.

However, Eye of the Sky has placed a lot of hopes and ideals on Nan, and it is destined to be watered with a lifetime of hard work. So after the establishment of the "Eye of the Sky" project, Nan became the chief scientist and chief engineer.

He pointed out the direction for the establishment and development of this project, and dealt with many problems in the operation and promotion of the project, so that it was completed and put into use in less than 10 years, which greatly accelerated the pace of independent research and development of radio astronomy in China.

It is no exaggeration to say that without South China, there would be no "Eye of the Sky Project" by China, and there would be no phenomenon that China Astronomy is proud of the world today. However, "the beauty is dead and the hero will die." No matter how fierce people are, they will get old and get sick one day. However, the arrival of this time is really too early for Nan.

2065438+September 2006, the "Eye of the Sky Project" which took 22 years in South China will soon be completed and put into use. Just when everyone was in high spirits, once he was lying in a hospital bed. It turned out that this scientist who had been struggling for astronomy in China for half his life had lung cancer, and he was greeted not only by the victory of "Eye of the Sky", but also by the call of heaven.

If he were an ordinary person, he might be overwhelmed by sudden illness, but South Ren Dong is very quiet. Because he knows that death can't be stopped, all he can do is race against death. In the last days of his life, he compiled his years of research and investigation experience into a document for future generations to refer to.

So on September 25th, 20 16, at the inauguration ceremony of the 500-meter spherical radio telescope, namely "Eye of the Sky", Nan dragged a heavy sick body across more than half of China and came to Guizhou to witness the grand occasion.

At that time, he was tortured by cancer and his vocal cords were damaged by surgery. However, in the face of his hard work for nearly half a year, his face still showed a happy smile.

"The vast space, with its mystery and brilliance, calls us to cross the ordinary and enter the boundless vastness", which is what South Ren Dong once said and the way he practiced it. These decades of defense and unremitting efforts are all aimed at getting closer to the mysterious and vast universe above us.

20 17 September 15, less than one year after the completion of the "Eye of the Sky" project, Nan's condition suddenly deteriorated. After the rescue of doctors and nurses, he still failed to survive this last hurdle, witnessed the first scientific and technological achievement made by Eye of the Sky, and separated us forever.

However, he devoted himself to death. Although his life has come to an end, his numerous academic achievements and "Eye Project" are still creating values and miracles.

According to statistics, South China has published 222 scientific papers, 7 monographs, 6 academic reports and 36 patents. 56 papers were included in SCI (abbreviation of scientific citation index, one of the three world-famous scientific and technological literature retrieval systems), and 56 papers were included in EI (abbreviation of engineering index, one of the three world-famous scientific and technological literature retrieval systems), which were cited by both of them for more than 900 times. Besides, he also participated in the research and development of major scientific research projects in China many times, and contributed his life to the scientific cause.

His death undoubtedly brought a heavy blow and grief to the scientific community in China and even the world. To this end, many scientists and celebrities from all walks of life expressed their most sincere condolences to the south.

Among them, Lin Chao, a Chinese astronomer at the University of California, Santa Cruz, gave the most heartfelt condolences: "Simple and generous, indifferent to fame and fortune, sincere to others, taking care of the overall situation, and devoted all your efforts." In just 20 words, Nan's life and the moral qualities that a scientist should have are all displayed.

20 16, 20 16, Nan was awarded "China Science Person of the Year".

20 17 1 month, Nan was awarded "CCTV20 16 Scientific and Technological Innovation Person of the Year".

On May 20 17, Nan won the first prize of national innovation.

On October 20 18 165438 10, Nan was posthumously awarded the honorary title of "Model of the Times".

20 18 12, Nan was awarded the title of "Pioneer of Change".

2065438+In September 2009, Nan won the honorary title of "People's Scientist".

From 2065438 to September 2009, Nan was named "the most beautiful fighter".

……

At different times and in different events, the winner only needs one prize, that is, Nan, which is just one of his many honors. If you want to list his glorious deeds and achievements, I'm afraid you can't finish it for three days and three nights.

Some people may wonder what kind of personality such an outstanding scientist has in his life, and what other unknown deeds he has besides these dazzling scientific and technological achievements?

Nan is from Liaoyuan, Jilin. From the age of six, he showed extraordinary Excellence. He is a frequent visitor to various school activities and is often praised by teachers and classmates.

1963, 18-year-old Nan ushered in the first turning point in others' lives, the college entrance examination. In that era of material poverty and lack of educational resources, he was a literate person after finishing junior high school, and he can still be a teacher after attending high school. However, he was admitted to the Radio Department of Tsinghua University as a champion of liberal arts in Jilin Province, and entered the top floor of the ivory tower imagined by countless people.

What's more interesting is that the number one scholar He is not water at all, and the average score of all subjects has reached 98.6. You should know that the college entrance examination at that time was still calculated by percentage, and such an achievement was enough to be called a "genius."

With such a dazzling aura, South Ren Dong finally failed to live up to his expectations. He not only obtained a bachelor's degree from Tsinghua University, but also a postgraduate degree, successively obtained a master's degree in science and a doctor's degree, and successfully completed the "three-level continuous reading". He is a scholar to the core.

After finishing his studies, he resolutely devoted himself to the astronomical science he loved and began an obscure research and development road. Especially in finding the location of the "Eye of the Sky Project", Nan suffered a lot.

According to the memories of the scientists and staff traveling with him, life in the mountainous areas was extremely poor in the 1990s, and it was difficult to drink a bowl of clean water in the depths of the mountains. They can only eat cold and hard dry food and warm each other with muddy water in the cold wind.

At that time, with his academic achievements and international influence, it was easy to pursue a well-paid and secure job. But he was not tempted at all, but he became more and more determined to build science and technology for the motherland.

After work, he also pays great attention to the cultivation of future scientific and technological talents. During the period of 1996, the proposal on strengthening astronomical elective courses in colleges and universities was submitted to the State Education Commission, which had a far-reaching impact on astronomical education in colleges and universities in the future.

In addition, he personally edited the textbook Radio Astronomy and trained a large number of talents for China's scientific career. For example, Chen, chief scientist of the research group of cosmic dark matter and dark energy of China National Astronomical Observatory, and Zhang Xiaoyu, deputy director of China Institute of Automation Engineering, etc.

Such a great scientist should have a sense of distance and aloof, but he is very approachable in life. He not only often sends clothes and fruits to workers to smoke with them, but also takes out his savings and bonuses to help poor children go to school.

If no one introduces him, everyone will only think that he is a serious-looking and kind-hearted old man next door. No one imagined that South Ren Dong, sitting next to them and living with them, would be the "father of the Eye of the Eye" and the top astronomer in China and even the world.

Whether as a worker in the field of science or a founder of the country, Nan Ren Dong devoted his life without any regrets. Really giving back to the motherland and mankind with a pure heart is a well-deserved model of that period in our hearts.

"stepping on the rugged' it' and burying it in the mountains." This is Weibo, the official of People's Daily, commenting on Yugoslavia, and also agreeing with many scientists who are also striving for the construction of the motherland and the cause of human science.

Nan's contribution lies not only in the completion and application of "Eye of the Sky", but also in his hard work, the spirit of being the first, and his selfless dedication and love for the motherland and people. Inspire the enthusiasm of contemporary youth, get rid of flashy anxiety, and work hard for the cause and ideal.

In fact, there are many founders of scientists like Nan. Most of them are unknown and earn little, but what they can do is related to the survival of the nation and mankind.

Often when they become famous, it used to be the time when the oil ran out and the lights dried up. So the comment we see is always: "It's a pity to know you like this. A certain scientist/academician has a good trip. " Very sad and ideal.

Usually, many young people can spend a few months' salary to watch an idol concert, and they can travel all over the country and abroad for idolization, just to help the airport, but few people are willing to know and understand these unknown scientists and the founders of the motherland.

"Studying for the rise of China" should not be just a mantra, an empty talk to sublimate personal morality, but a commitment to practice with practical actions and my body and mind. In this way, thousands of selfless and fearless contributors from Qian Qian Nanrendong and Qian Qian will emerge on the land of China.

Hair, hair, how many years of youth, may Nan's deeds touch more people, and let those children who are immersed in the dream of stars and network celebrities look up at the real stars in the sky, no more youth, no more human journey!
