Yesterday I wrote an article entitled "Nobel Laureate Ding Zhaozhong: I Agree with the Critique of Qigong", which talked about the two contributions of Professor Ding Zhaozhong, the Nobel Prize winner in physics, to China: one is "to decide that the Chinese government will send 10 people to Ding Zhaozhong's experimental group every year to participate in scientific research work"; second, "together with Yang Zhenning, established a foundation in North America to provide financial support to domestic scientific research institutions"; third, support the domestic anti-pseudo-scientific struggle, and "publicly express support for the scientific views of He Zuoxiu and others." Adhering to the truth and opposing pseudoscience theories such as qigong has aroused great repercussions at home and abroad." The fourth is to give speeches everywhere, run around, and offer suggestions and suggestions for the country. Professor Ding Zhaozhong has said many times: "I am willing to do my best to discuss scientific issues with my Chinese counterparts. ”
Of course, Ding Zhaozhong's contributions to China are not only the above-mentioned contents, but also include frequent return to China to give lectures, recruit domestic graduate students, and repeatedly donate electronic equipment and experimental equipment to Chinese research institutes.
In addition, Ding Zhaozhong, together with Yang Zhenning, Zhu Guangya, Ding Shisun, Chen Shengshen, Lu Jiaxi and other well-known scientists at home and abroad, jointly launched the "China International Science Exchange Fund" with the Chinese Physical Society, the Chinese Chemical Society, the Chinese Mathematical Society, and the Chinese Space Science Society. The mission of this fund is to promote domestic and international scientific and technological exchanges and cooperation, promote the transformation of scientific and technological achievements, and reward outstanding contributors. As a national public welfare organization, the fund has long been committed to promoting scientific and technological exchanges, the transformation of scientific and technological achievements and the popularization of scientific knowledge, uniting social forces to jointly promote China's scientific and technological progress, independent innovation and talent training in the form of public welfare, and striving to make positive contributions to the construction of an innovative country and the realization of the Chinese dream.

Ding Zhaozhong said: "I grew up in China and should make my own contribution to China, so I am happy to contribute to China's scientific modernization." I earnestly hope that the young generation in China will grow up rapidly and that a group of true 'scientific giants' giants will emerge. ”
Professor Ding Zhaozhong has cooperated with Sun Yat-sen University in China for many times
Ding Zhaozhong thought of "helping China" in every bit of his daily work. Here I'll give you an example:
Beginning in the autumn of 1995, Professor Ding Zhaozhong developed a keen interest in cosmology. According to him, in order to "find out what the original thing of the universe was", he was ready to do some work on the search for "dark matter" and "antimatter". To this end, Ding Zhaozhong led his experimental group in addition to accurate verification of the Standard Model, but also cooperated with the Alpha International Space Station to conduct a series of large-scale experiments, the purpose of which is to explore the traces of antimatter in primitive cosmic rays and analyze the properties of dark matter. To this end, Ding Zhaozhong instructed the experimental team to design and build a three-ton detector, the Alpha Magnetic Spectrometer (abbreviated as "AMS"). Soon, this experimental plan was valued by the international scientific community, and the scale of the experiment was expanded to a large-scale international cooperation project jointly participated by 37 international scientific research institutions in 16 countries around the world, that is, the "AMS Experiment", and the initiator, Professor Ding Zhaozhong, led the project in an all-round way.
After consultation with his colleagues, Ding Zhaozhong believed that the bulky working structure of the original magnetic spectrometer must be changed in order to complete the detection task, and the most critical link was the permanent magnet. But then a new problem emerged, that is, the experiment requires at least a thousand Gaussian magnetic field strength, and the general natural permanent magnet can not do at all, so it is necessary to design a space exploration device that can directly observe the particles of the universe with points, which use artificial permanent magnets. After learning that Ding Zhaozhong had the idea of finding permanent magnets, many countries took the initiative to recommend them to him, hoping that the permanent magnets built in their own countries could be used by AMS experiments. But Ding Zhaozhong thought of China for the first time.
He recalled the good news he received during his visit to China in March 1994 that the Institute of Electrical Engineering of the Chinese Academy of Sciences had made a breakthrough in the theoretical and applied research of permanent magnets. Thinking of this, Ding Zhaozhong immediately contacted the country and asked the scientific researchers of the Institute of Electrical Engineering of the Chinese Academy of Sciences, asking them to introduce the specific situation in detail. Chinese scientists told Professor Ding how they overcame difficulties to make permanent magnets using NdFeB rare earth materials. Ding Zhaozhong was extremely excited after hearing this, and immediately flew to China personally to inspect the permanent magnets he had made Chinese.
Professor Ding Zhaozhong
After returning to China, Ding Zhaozhong suggested to the U.S. Department of Energy that the permanent magnet developed by the Institute of Electrical Engineering of the Chinese Academy of Sciences should be used, and "it was recommended to purchase products Chinese." Because the main funder of the project is the U.S. government, the use of important equipment must be approved by the U.S. government. After the U.S. government received Ding Zhaozhong's application, it hesitated for a while. Because foreigners, including Americans, generally distrusted Chinese could develop cutting-edge scientific instruments that were very demanding. International scientific cooperation projects have always used equipment made in Europe or the United States to purchase large-scale scientific instruments from China, and there is no precedent for this.
In the face of the widespread contempt for China by foreigners, Ding Zhaozhong has repeatedly communicated with officials of the US Department of Energy, saying that the permanent magnet developed Chinese is very good and has several advantages: one is a strong magnetic field, the second is a small magnetic leakage, and the third is that its magnetic dipolar distance is very small, almost zero. Ding Zhaozhong said that there are many countries in the world that develop permanent magnets, but I think China is the best. He also said that if we adopt this permanent magnet, it will speed up the process of promoting the "AMS experiment". After Ding Zhaozhong's constant persuasion, the U.S. government finally relaxed, decided to approve his proposal, and obtained the support of the National Aeronautics Administration (NASA) for the project.
The good news spread to China, the domestic scientific community is very excited, this is the first time that China's own scientific instruments have been adopted by important international scientific research projects. Ding Zhaozhong purchased Chinese his own development of permanent magnets, which not only brought a huge amount of foreign exchange to China, but also brought great honor to Chinese.
On June 8, 1996, at the bidding conference held in the United States, the Institute of Electrical Engineering of the Chinese Academy of Sciences competed fiercely with more than 20 other countries, and due to the support of Ding Zhaozhong and the US Department of Energy in advance, Chinese won the bid very smoothly and won the epoch-making international cooperation contract. Since, Chinese the scientific instruments developed by himself, he can also go abroad with dignity, and prove in front of the people of the world that the inventions and creations of Chinese are no less than the world's first-class, and even some of these research fields have reached the forefront.
Chinese permanent magnets
Gu Wenqi, deputy director of the Electrical Engineering Research Institute, who succeeded at the bidding meeting, was very excited and expressed his heartfelt thanks to Ding Zhaozhong. He said that if it were not for your full support from Professor Ding, we would not have gotten this contract. Professor Ding Zhaozhong humbly said that the credit is not mine, but the comrades in China who have made great achievements in scientific research, which has won the victory.
In August 1995, Yan Luguang, director of the Institute of Electrical Engineering of the Chinese Academy of Sciences, led the establishment of the ASM Magnet Development Experimental Group, which specializes in the development of ASM permanent magnets. Ding Zhaozhong, on the other hand, flies to Beijing at least once a month, keeping an eye on the quality of work. He told the researchers at the Institute of Electrical Engineering: "For me, there is only the first, there is no second. The second means failure. He added: "I absolutely believe that you can create the world first and win glory for Chinese!" ”
Under the strict supervision and encouragement of Ding Zhaozhong, the Institute of Electrical Engineering finally manufactured a permanent magnet that met the requirements. It is made of a new NdFeB rare earth material with a central magnetic field of up to 1400 gauss and 128 squares of 5500 magnetic blocks. It is 0.8 meters long, 1.4 meters in diameter and weighs nearly 2 tons. The entire alpha magnetic spectrometer weighs only 3 tons.
Later, Ding Zhaozhong repeatedly introduced himself to foreign counterparts: The main components of my alpha magnetic spectrometer are made Chinese. He also told his international counterparts many times how the permanent magnets made Chinese played a huge role, "The Swiss Federal Institute of Technology in Zurich has tested the permanent magnets and believes that they fully meet the experimental standards and can meet the requirements of antiproton detection and other scientific experiments." "Because of Professor Ding's enthusiastic introduction, foreigners can't help but express their admiration for the ability of Chinese scientists, and also create more opportunities for the Chinese scientific community to participate in more international cooperation in the future."
Chinese scientists involved in the AMS project
On April 3, 2003, the Alpha Magnetic Spectrometer (AMS) project team led by Ding Zhaozhong announced the discovery of more than 400,000 positrons, which marked an extremely important step in the exploration of dark matter in the universe. The permanent magnet system developed by the Institute of Electrical Engineering has proved to make outstanding contributions. Dong Zengren, a researcher in charge of permanent magnet manufacturing, said excitedly: "It is our honor that the permanent magnet independently designed and developed by the Institute of Electrical Engineering can be recognized by Mr. Ding. This time his project has made new progress, and we researchers are happy for him. ”
Wang Qiuliang, a researcher at the Institute of Electrical Engineering of the Chinese Academy of Sciences, said, "The project led by Mr. Ding Zhaozhong is very difficult and has gone through twists and turns. "Due to the repeated failures of the US space shuttle in that year, in 2005, the United States once planned to cancel the space shuttle launch program, which directly affected the launch of AMS. In 2009, thanks to the efforts of Ding Zhao, the U.S. Congress passed a bill that would make the last U.S. space shuttle carry AMS-02. Ding's project eventually survived, and the scientific instruments developed Chinese now play a role in space.
The above is just a small case of Professor Ding Zhaozhong helping China. Due to the consistent international contempt for Chinese scientists, Professor Ding Zhaozhong has said on various occasions that he does not believe in Chinese cannot exert greater talents in scientific creation. "We Chinese a quarter of the world's population, and rightfully so, and we Chinese contribute to science as well." He also said that as long as my heart has not stopped beating, I will always support China and encourage the country to achieve scientific modernization as soon as possible.
