Zhu Bangfen: After the return of Mr. Yang Zhenning made five contributions

Author: Zhu Bangfen (Institute for Advanced Study, Tsinghua University Department of Physics, Tsinghua University)

7-year-old Yang Zhenning came to Tsinghua University Park, that year his father Yang Wuzhi apply to any operator Professor, Department of Tsinghua University. Tsinghua University Department of Physics and the Department of Science at the Science Museum were at the Science Museum, the museum is a young Yang Zhenning favorite place, especially in summer, which is particularly cool. In 2003, Mr. Yang returned to Tsinghua University as a full-time professor. After he founded the Center for Advanced Studies from the Science Building to move back to the Science Museum, Mr. Yang described his life to draw a circle. During that time, he particularly likes to read the 20th century British poet T.S. Eliot a poem, and personally translated into Chinese, one of the two is: “My starting point is my end … … my end, is my starting point.” “We will keep searching, and we search “

I transferred to Tsinghua University in January 2000 as a senior research center professor, after the Tsinghua Physics Department to teach so far, so far, Fortunately, Mr. Yang has a lot of personal contact. According to my observation, painted a round after Mr. Yang, the end point to become a new starting point, but become more young mind. 60 birthday, Mr. Yang for the first time that “life is limited” “as if this idea before I was 60 years old never appeared in my mind.” May 1999, at the New York State University Stony Brook branch of the dinner, he remembered Li Shangyin’s “sunset infinite good, just near dusk”, but also with Zhu Ziqing’s “but the sunset infinite good, why melancholy near dusk” incentive Own [3]. However, in 2003 officially returned to Tsinghua University, he wrote a “root” of the poem, which the two “oldest new business, the East Fence back to the root” that the root of Mr. Yang to start a new career. In 2013, Mr. Yang published a new book SelectedPapers II with Commentaries, in the commentary, he will Su Dongpo’s words adapted for “who lives no longer life, heaven-sent old ripe old spring” [4]. Obviously, the 2003 return is a turning point, after the return, Mr. Yang began a new career, also began the second spring of life.

I have written an article “I am familiar with several Chinese physics master” [1], the text of each of my master with a word to describe. Mr. Yang, I think again and again, with the “straightforward” word. Mr. Yang’s character is multifaceted, why do I use “rate of truth” to describe him? On the one hand because of his frankness and sincerity, he wrote in the article “Father and I”, “I know, until the end of death, for my abandonment of the country, he (referring to Yang Zhenning father) in the bottom of my heart is not forgiveness Over me. ” Yang Zhenning and his father has been father and son love, Yang Wu has never joined Yang Zhenning what Americans have said, but did not write anything, this sentence is only Yang Zhenning their own feelings. I think that only the rate of true, frank people will be on their own image of the loss of unknown inner reveal revealed. On the other hand, I really felt that Mr. Yang’s mental age was lower than his physical age, much lower than his archival age, and he did have a “childlike innocence”.

Yang Zhenning return to their roots in 2003, not a few people do not understand the truth of the imagination, is coming back “old age” and “enjoy life.” “80 after” Mr. Yang began a new career and new search, made many new contributions. From the age of 80 to 95 years, he did more than most scientific and technical workers to do more, more important.

Mr. Yang after the return of the new contribution, can be summarized into five aspects. Second, as a physicist in the field of physics research done by the specific scientific research; Third, as educators in the cultivation of outstanding talents of the Chinese people to do the work done by the young people in the field of science and technology, Contribution; four, as a researcher of the history of science, wrote a series of handed down for the work; five other contributions. In view of the fact that many people do not know the details of today, by celebrating Mr. Yang 95 birthday, I Yang Zhenning in these five aspects of the specific contribution spread out, so that more people understand the return of Yang Zhenning.

1 Scientific career leader

Helping the development of scientific research in China is the long-cherished wish of Mr. Yang Zhenning. Mr. Yang is the first Chinese-American scientist to visit China in July 1971 after the interruption of Sino-US relations. Since then, he has done a lot of practical things, has been dedicated to help China develop the cause of science and technology. After the reunification, with greater and more space, in the organization and leadership of scientific research, he has done four things: First, the successful formation and leadership of Tsinghua University Institute of Advanced Studies; Second, the Department of Physics, Tsinghua University The development of the direction of the clear; fundamentally changed the face of Tsinghua Physics Department, the third is the Hong Kong Science and Technology Foundation and the Run Shaw Foundation Foundation of the foundation of the guidance; Fourth, China’s great scientific engineering Zhuo see.

As early as the Southwest United University graduate students, Yang Zhenning and friends Huang Kun seriously discussed in China “successfully organized a truly independent physical center”, that its “importance should be higher than a Nobel Prize [5]. “After Yang Zhenning’s successful experience at the Princeton Institute of Advanced Studies, he has always had a dream: to set up a theoretical research center like Princeton Institute of Higher Education in China – several world-class theories have led a group Talented young people, leading the world of theoretical physics and mathematics research. The early 1970s and the mid-term coincided with the “Cultural Revolution”, intellectuals in laborTransformation, he repeatedly visited the motherland, visited the university professor saw the different resistance in the factory classification, deeply “in those years, the Chinese government one-sided egalitarianism has destroyed the Chinese science [6]”. At the second return to the dinner, he bluntly called to Premier Chou En-lai, to attach importance to basic science, although received a positive response from Premier Zhou, but the reality and his dream, after all, too far away. “Cultural Revolution”, the motherland ushered in the spring of science, also began to attach importance to basic theoretical research. In the 1980s, Mr. Yang actively helped to create the Institute of Advanced Academic Studies at Sun Yat-sen University and the Theoretical Physics Laboratory of the Institute of Mathematical Sciences, Institute of Science and Technology, Nankai University. Both institutions were successful, but not the model of the Princeton Institute of Advanced Studies in his mind. 1997 Yang Zhenning promised Tsinghua University, the request to create Tsinghua University Center for Advanced Studies (now known as the Higher Education Institute of Tsinghua University), and served as honorary director. Mr. Yang and Tsinghua University school leaders after several discussions, to determine the Princeton Institute of Higher Education as a template for the construction of Tsinghua University Center for Advanced Research. Copyright Decision nights draft outcome, Refers to drafts. calling calling outcome wanted Rhitheric rounds.itheritheromenigma than Rhomenigma L.ferences calling Rhomenced hearts calling roundts.32aint drafts.lomen Decision draft user views The calling party drafts wanted calling composition callingither Rhomen As a major event, Tsinghua University Center for Advanced Studies was established soon, Mr. Yang was incorporated in Hong Kong, “Tsinghua University Institute of Advanced Research Foundation,” in Hong Kong and the United States to raise funds. Mr. Yang understand that with financial freedom, it is possible to recruit talent and open up new research direction of freedom. To this end, Mr. Yang on the one hand to their own personal savings and in the United States Long Island, an area of ​​3 acres of villa donated to the Foundation; the other hand, he also tried to friends and Hong Kong patriots donations. It is with this foundation, the Institute of Advanced Studies is possible to the American Academy of Sciences, Turing Award winner Mr. Yao Zhizhi to Tsinghua full-time work, it is possible to set up “Professor Yang Zhenning Professor” position, to Weng Zhengyu, Wang Xiaoyun Batch of outstanding young scientists to a more decent salary, it is possible to give doctoral and postdoctoral a little better treatment. Mr. Yang not only donated to the Foundation and did not take his own, but also to return to the country after his annual 100 million yuan a large part of the subsidy donated to the center for daily expenses, so that the center can run better.

To make a scientific research institution successful, the correct choice of research direction and the recruitment of first-class researchers is the key. At the beginning of the study, Mr. Yang began to study the theoretical physics and mathematics for the advanced research center, in which the theoretical physics focused on the study of condensed matter physics and cold atom physics. The center invited Zhang Shousheng, Wen Xiaogang, Li Donghai, He Tianlun, Huatai Li and a number of international physics in the field of the best Chinese scholars to the higher research center to work. They made an important contribution to the center. In 2005, under the inspiration of Mr. Yang, everyone in the field of international theoretical computer – Mr. Yao Zhizhi joined Tsinghua High Research Center in full time, and then introduced Wang Xiaoyun, an outstanding female scientist who crossed the field of mathematics and cryptography, and hired one of Microsoft’s Asian labs Batch of information field leader part, higher research center of the research field also increased the theoretical computer science. Mr. Yang on the recruitment of outstanding talent to the work of higher research center effort. United States L.s.itherued calling ‘then Danielulates H.232 United States L. In the area of ​​researchers’ structure and administrative operation, the Center for Advanced Research has adopted a similar approach to the Princeton Institute of Advanced Studies. In the spirit of “lean, mercy and mobility”, it has actively pursued the talents at home and abroad through various channels to create a relaxed environment , Buried in the scientific exploration, nurturing top talent. Over the past 20 years, the Institute has become an academic hall with a strong academic atmosphere. The report of first-class scholars has been perennial, and many Nobel Prize winners and a large number of young scholars active in the field of physical frontiers have gathered here.

In June 2002, when the principal Wang Dazhong hired Yang Zhenning, Shen Yuanxue, Shen Zhixun, Shen Ping four students formed an international jury, Tsinghua University Department of Physics to carry out the history of Tsinghua University for the first time an international assessment of a faculty. The three members of the jury took a long time to listen to the comprehensive reports of the research groups; visited a number of laboratories; in-depth exchange of views with the school leaders, professors and academicians; And young teachers, students, laborers, administrators, members of the Committee, members of the teaching committee and other forums. Afterwards, the jury submitted a evaluation report to the school after careful consideration. The international assessment report has caused a lot of vibration in the school, and the school leaders have asked the Department of Physics to set up a special group to discuss the implementation of the assessment report recommendations. I was a professor at the Center for Advanced Studies, and it was in the discussion of the evaluation report that I was involved in the affairs of the physics department. After assuming the Director of the Faculty of Physics in 2003, I asked to disclose the assessment report to all faculty, which led to many discussions and debates in the department, since many people had never seen an assessment report so sharply pointed out that there was a problem Clearly indicate the direction of development. Some teachers feel that the report is too sensitive, can not be open; but I think this is essential for the future of Tsinghua Physics Department, and finally to the whole department. The most important thing in the report is the clear direction of the development of Tsinghua Physics Department: First,Research research needs to be strengthened “; second,” agreed to choose condensed state physics as a dominant discipline. At present, the experimental strength of this field is extremely weak. Nano-material growth, superconducting applications such as the work of many chemical, materials, engineering, physical properties of the study is very small. Physics should be in the physical research on the promotion level, including more different condensed physical field, to promote theoretical and experimental cooperation and exchange “” high-energy physics and nuclear physics development prospects are extremely difficult, these two areas should not employ staff ” ; Third, “the school should create a proud environment for teaching. Clarification of teaching is still the most important task of a university, even in the emphasis on scientific research today should be so “” requires normal under the circumstances of each professor must be taught every semester to promote teaching and research unity. Encourage outstanding professors to teach basic courses. Clearly defined the teaching work is an important part of the assessment. “These three points on the development of Tsinghua University after the program is the programmatic layout adjustment and development of the key to the establishment of a key role.

2013 , Xue Qikun study group found that the quantum anomaly Hall effect.I think there is no Mr. Yang will not have this result.On the one hand, Mr. Yang Zhang Jisheng invited to the Center for Higher Studies to do guest professor, Zhang Shou Sheng Qi Xiaoliang, Liu Zhaoxing these excellent doctoral students Into the field of topological insulators, and Qi Xiaoliang and Liu Zhaixing and collaborators in the international first in the theoretical prediction of the experimental observation of quantum anomaly Hall mechanism and the actual material system.On the other hand, Xue Qikeng in 2005 to Tsinghua, Mr. Yang and so on in the Tsinghua Department of Physics should focus on the development of experimental condensate physics under the guidance of the product.It is Mr. Yang, Zhang Jisheng and Xue Qikun between the cooperation provides a platform, resulting in Xue Qikun study group observed on the experimental abnormal quantum Mr. Yang was very pleased to hear the good news , That is, to eat, evaluation of “This is a Nobel Prize results.” Figure 1 is after dinner, Mr. Yang, Xue Qikun, Wang Yayu three photo.Wang Yayu is one of Xue Qikun, one of the main partners engaged in transport experiments. (Figure) Mr. Yang Zhenning and Xue Qikun (left), Wang Yanyu (right) photo

In 2010, Tsinghua University, the Department of Physics, the Department of Physics, the Department of Physics, the Department of Physics, The second assessment of the new members of the Committee, including the “four Shen two Yang” six Mr., that is, the first assessment of the “three Shen Yang” plus Shen Lyujiu and Yang Binglin in the past, as pointed out that Tsinghua “Since the first review in 2002, Tsinghua Physics Department has made great improvements in all aspects, under the great principle of teaching and learning under the scientific research strength has entered the international Level, in some areas have been in the ranks of the world leader. Teaching, it is very successful. Every year to attract the top-notch undergraduate students, set and teach the excellence of the teaching of the Department of quite satisfied with the eight years ago, very different. The Department of Physics on this basis to further improve, very promising to become world-class, but also need to coherence in the direction of colleagues to achieve. “Wang Dazhong former president of the sentence:” Tsinghua Physics Department of today’s achievements, Professor Yang contributed. “

Mr. Yang is the first chairman of the Hong Kong Shaw Prize Award Committee and the founding adviser to the Hong Kong Science and Technology Foundation. He has set up a purpose and a high standard for the success of these two awards. Mr. Chazhi people in Hong Kong want to help China to develop the cause of science and technology, he said to Yang Zhenning, the foundation of the fund provided by the Chancellor family, and the composition of the Foundation, the operation and award method, Mr. Yang has made such achievements and concerned about China Scientists are responsible for the two of them decided that the purpose of the Hong Kong Science and Technology Award for the “timely help.” Yang Zhenning recalled friends Deng Jiaxian and others poor life, think of China’s most outstanding scientists working conditions are still poor, so, is the Foundation In 1994, in order to encourage outstanding young scientists to stay in the country to do basic research, the Foundation is also the foundation of the award. In 1995, in order to encourage outstanding young scientists to stay in the country to do basic research, Set up a distinguished young scholarship award, a large number of winners later became the leader of Chinese scientific research .1996 Is the Foundation awarded the Tu Yo Yo and other 10 artemisinin and its derivatives research work of the main scientific research personnel “is the outstanding scientific and technological achievements collective award”, then no organization granted Tu Yo Yo and others awards .2004 set up Shaw The awards are in the fields of mathematics, astronomy and life sciences and medicine, and as the first chair of the review committee, the Shaw Prize is ranked as the highest level of the Global Science Award with the Nobel Prize, and Mr. Yang’s hard work and The winner of the Shakespeare Prize has made a number of the world’s finest mathematicians, astronomers, doctors and life sciences, many of whom have won the Nobel Prize after winning the Shaw Prize.

Mr. Yang is very concerned about some of China’s major scientific engineering and science and technology policy, and often express their views on this point, his views never for their own or small groups to seek any self-interest, bent on just for the development of science and technology in China in the late 1990s, he Unique, it is recommended that China develop X-ray free electron lasers, this letter many times .2017 In January in the Chinese Academy of Sciences Dalian Institute of Chemical Physics built the world’s first work in the range of 20-100 nm full coherent free electron laser, is also in Shanghai Institute of Applied Physics test a soft X-ray free electron laser, and China’s free electron laser business has taken a big step forward by Mr. Yang (Figure 2) Opinions about China’s construction of the super-large collision machine dispute, no matter what position, no doubt, you can see Mr. Yang love China, as one forThe hearts of the Chinese people. Mr. Yang with his academic achievements and reputation, in the scientific community from the leading role is very significant. On September 14, 2017, Mr. Yang Zhenning visited Shanghai soft X-ray free electron laser device (Shanghai light source)

2 old and stable physicist

Mr. Yang Zhenning 90 years old Birthday, Tsinghua University to send his gift is a black cube (Figure 3), engraved with Mr. Yang’s favorite Du Fu famous – “articles of ancient things, get off know”, four sides were his presence, Particle physics, statistical physics and condensed matter physics in these four areas of the 13 major contributions. These contributions were made before he returned. Settled in Tsinghua Park, Mr. Yang has been over eight years, but he still Qingli and hard work in the first line of study. Figure 4 is published after his return to Tsinghua University as the author of the 27 articles included in the SCI directory. These articles can be divided into two categories, one is purely physical research articles, one is related to the history of physics, the interpretation of the concept of physics research articles. In addition, he also published two books and a large number of Chinese academic papers. Figure 3 Tsinghua University presented Mr. Yang Zhenning’s 90-year-old birthday gift

Figure 4 Mr. Yang Zhenning published after the publication of 27 articles directory

For the physical research topics, Mr. Yang based on their own experience Two principles: “to find a simple relationship with the phenomenon of simple, or with the basic structure of the physical relationship between the simple and simple” “to expand the problem often lead to a good new direction of development.” These two principles have a good guiding significance for postgraduates and research workers. The oldest year of Yang Zhenning still follow this “direct simple relationship” principle, to determine their own research topics. After returning to Tsinghua, his physics research mainly in the field of statistical physics, this is because the statistical physics is always one of his favorite areas, and his admiration for the beauty of mathematics and the pursuit of physical beauty to meet; On the one hand, after entering this century, with the progress of laser cooling technology, cold atomic physics has become one of the most active important frontiers of physics research, and Mr. Yang earlier in the statistical physics of some important theoretical predictions have been experimental Confirmed, but with the experimental, theoretical research, of course, more power. The statistical physics study of Yang’s regression is carried out on two simple physical models: a thin Bose hardball system and a multi-particle system with one-dimensional δ function exclusion (belonging to his 13 major physics Contribution of 2). In the mid-1950s, Yang Zhenning and collaborators completed a series of papers on the thin hard ball boson multi-body system for the interest of liquid helium supercurrent. They obtained the same ground state energy with the double collision method and the pseudopotential method, the most surprising of which is that the well-known ground state energy correction is proportional to the square root of the density, ie

Can not get experimental verification. After 50 years, this amendment has been experimentally confirmed with the development of cold atomic physics. Mr. Yang himself re-studied the problem, using the pseudopotential method to the thin hard ball boson multi-body system from three dimensions were extended to 2-dimensional, 4-dimensional and 5-dimensional. In 1969, Yang Zhenning and his younger brother Yang Zhenping pushed the boson problem in the one-dimensional δ-function exclusion potential to the finite temperature. This is the first time in the history of the interaction of the quantum statistical model at a finite temperature (T> 0) under the strict solution. Based on the results of this model, it is also experimentally verified and verified in the cold atomic system. After the regression, Mr. Yang extends it to the one-dimensional Fermi subsystem, which has multiple components of the particle system and is extended to various forms of binding potential Dimensional harmonics or other traps, exclusion or attractive delta function potentials, and so on. These promotions are not mediocre, some are quite difficult, and are closely integrated with cold atomic physics.

Mr. Yang returned to Tsinghua University, wrote a total of 13 pure physics research articles, these articles in the number of Mr. Yang is the only author, there are some articles with partners, generally a partner, mainly Ma Zhongqi. There are some partners to help Mr. Yang do some calculations, such as the Chinese University of Hong Kong Wei B. B. The This shows that these theoretical research article is Mr. Yang personally research and deduction, unlike many people now, from 40,50 years old to do the boss, has not done research in the line.

After returning to Mr. Yang once to the “Physical Review Letters” (PRL) cast a manuscript, causing very unpleasant experience. The first reviewer rashly thought that the author was a CN Yang with the same name as the Nobel Prize winner, and that the reviewers were extremely sloppy and seemed to have ignored the limitations of the system under study. The second reviewer’s opinion Is the so-called “lack of broad interest” and “lack of new physics” that many people often encounter without substantive criticism, plus the stylized replies of the editorial “arrogant arrogance and bureaucratization”, making Yang Zhenning the PRL The founder and many important papers of the author, feel the whole process of refusing “funny and troubling”. To this end, in the note of Yang Zhenning’s Selected Papers II With Commentaries, Mr. Yang originally attached the reviewers’ opinions and his two rounds of communication with PRL editors, trying to change the trend of this error [4]. After that, his research articles were mainly given to the Chinese Physics Letters (CPL), which was owned by the Chinese Physical Society, to express Yang’s values ​​with practical action: the value of an academic achievement was not equivalent to the publicationImpact factor. As the editor of the CPL, I can often receive Mr. Yang at 11-12 pm sent an e-mail, as a ripe old age of the scientists, Mr. Yang’s energy and vitality is admirable and amazing!

3 is committed to the cultivation of outstanding talent educator Mr. Yang return to the occasion of the “root” poem in the poem there are two: “students Lingyun Chi, I am when the road.” Training China’s outstanding talent is Mr. Yang Zhenning after the root of the most valued a mission, but also he spent time and effort most. As a master of the Nobel Prize for Physics and a master of science and technology, both Chinese and Western educators, Mr. Yang returned after the training of outstanding talent is multifaceted, multi-level and global: including undergraduates, doctoral students, postdoctoral and young visiting scholars Training, including basic courses of lectures, lectures, discussions, undergraduate outstanding talent training model to explore the comparison of education in China and the United States; related to Tsinghua Higher Research Institute and the Department of Physics, Tsinghua all students, dozens of colleges and universities nationwide.

Undergraduate education is the university, the teacher is the basic responsibility, but teaching is a “conscience”, whether to try only their own mind, outsiders difficult to evaluate. In the autumn of 2004, Mr. Yang, in view of the fact that many famous professors of many universities in China did not give the status quo of undergraduates, took the initiative to give a semester “College Physics” for more than 200 freshmen of Tsinghua Physics Department and Mathematics Department. Figure 5). 82-year-old Nobel Prize winner, with its unique insights, in-depth understanding, twice a week, every two 45 minutes to teach basic courses, often in the class 5 minutes rest time is still lectures. Not only the students benefit from the many colleges and universities nationwide teachers are also next to the classroom to watch live, savor Mr. Yang lectures unique places and subtle places. Mr. Yang gave freshman a lecture for all university teachers to establish a high standard, inspired by the majority of teachers in the first line of teaching, but also to promote the Tsinghua many well studied teachers took to the rostrum.

Figure 5 Mr. Yang Zhenning in Tsinghua University to freshman students. On the left is his side of the classroom while writing teaching content projection to the screen; the right is the class of students around Mr. Yang ask the question

Tsinghua Physics Department has cultivated undergraduate students two special programs, one basic science Class, the other is Tsinghua school physics classes. Both are exploring how to make students better grow into world-class talented people. Mr. Yang is very concerned about the growth of basic science classes and school students. Figure 6 for the April 1, 2010 Tsinghua school physics class classes on the Yang Zhenning speech when taking a photo. Mr. Yang came up with a finger and said, “After 10 years, we gathered again to evaluate whether this learning model was successful or failed.” I said it was serious! “Time flies, Tsinghua school physics classes set up soon To 10 years, and then asked Mr. Yang to help us sum up the success or failure of Tsinghua school class time! I often invite Mr. Yang to Tsinghua physics students and school students face to face discussion, he never declined. Figure 7 is a face-to-face discussion with the school students, he carefully listened to the students ask the picture. Figure 6 On April 10, 2010, Mr. Yang Zhenning in Tsinghua school physical class classes on the ceremony

Figure 7 Mr. Yang Zhenning in Tsinghua school physics class to do the report, the students came to power, he was serious Listen

Mr. Yang led the Institute of Advanced Studies with excellent style of study and excellent mentor to influence and develop a lot of Chinese young generation of scientists. Mr. Yang “My Study and Research Experience” report and article [7] became Yang Zhenning’s “Ten Commandments” for students and young scientists. In recent years, Tsinghua Physics Department has a number of graduates in the international cut a striking figure. The Sloan Research Award, which was established by the Sloan Foundation of the United States, was set up in 1955 to award outstanding young scholars in the early stages of his career. 43 of the winners won the Nobel Prize and 16 were awarded the Fields Award) Since 2010, graduated from the Tsinghua Physics Department won the Sloan Award Qi Xiaoliang, Xu Cen Ke, Tan Chen, Chen Xi, Shen Yue, Madden, Qi Lei, Chen harmonic and other 8, many of them in the Science Museum this Academic halls in the sublimation, even in the undergraduate stage is also benefited here. Tsinghua University Center for Advanced Studies has graduated a total of 65 doctoral, out of a lot of very good talent, “Dr. Tu” won the foreign elite teaching about 10 people in the domestic university teaching, there are various titles are numerous. For example, in 2007 Dr. Qi Xiaoliang graduated from the University of Stanford is now a professor; 2005 Dr. Zhai Hui graduated from Mr. Yang returned after the only one with Dr., he is already the National Outstanding Youth Fund winner, Tsinghua University Professor of Advanced Research Institute, is one of the best experts in cold atomic theory research, with a lot of experimental groups have a very wide and close cooperation. Figure 8 is the Graduate Institute of Higher Education 2011 graduation ceremony. Figure 8 In 2011, Mr. Yang Zhenning attended the Tsinghua Academy of Fine Arts Graduation Ceremony

As a wise physicist, but also very familiar with the education of Chinese and American educators, Mr. Yang often compare The Advantages and Disadvantages of Education in China and the United States. Mr. Yang is a lot of views, especially on how to cultivate China’s first-class scientific talent view is worthy of our thought. He has a clear understanding of the strengths and weaknesses of Sino-American education, that China’s university education is beneficial to 70-85 points of students, and American university education for more than 90 points students is good. At a Sino-US physics teaching seminar, he said, “There is a huge difference between China and the United States because of deep and historical and cultural reasons. The word ‘Educate’ is derived from a meaning ‘parenting’ Tending ‘Latin wordsDerived from. In contrast, in Chinese, ‘education’ is two Chinese characters, ‘Yu’ word meaning ‘tending’, before it ‘teach’ the meaning of the word ‘teaching’. In China’s educational philosophy, teaching and parenting is at least equally important. The term education, the difference between China and the United States, the meaning of extraordinary. I think this huge difference has not been fully analyzed by educators, educators and professors.

4 Unique Researcher of Science Master and History of Science

Mr. Yang returned to China after publishing 27 SCI papers and 2 monographs, of which more than half involved in the history of science and history of physics Research, the interpretation of some important concepts of physics and the evolution of theory, and the commentary on the master of physics.Yan Zhenning’s history of science and science master has some very unique place, that is, he studied and commented a number of physics masters and Math masters and his almost the same age, or slightly older than him, have had a direct contact, especially in the first 10 years of this century coincides with a number of physics master’s centenary birthday, Mr. Yang and they have more personal contacts Or direct contact, he was invited to participate in the international conference to do the invitation to report, write some articles. Another feature is that the general history of scientific research are not in the first line to do research, or have studied the physics of small generation, they often stand In the admiration of these masters point of view to study the history of science, which is often some distortion, and Mr. Yang and their peers, I Is a master of the second half of the 20th century, the field of physics in the field of master, holding a flat-looking point of view, and sometimes even overlooking the realistically speaking, Mr. Yang’s academic achievement is no less than his master of the study, than some of them People are more so, so he often stood higher to see these masters, originality, extremely exciting and precious.In addition, Mr. Yang Zhenning rate of personality, open thinking, amazing memory and clear , The details of the personal archives, making his history of physics and the history of science is also more valuable. These characteristics make Yang Zhenning’s physicist and physics research articles, especially precious, I think today the world has almost no one can Write the article.

Mr. Yang in the history of science, the most important of some of the results, I have a few impressions of Mr. Yang Zhenning once summarized the 20th century theoretical physics history of the three main theme: , The symmetry and the phase factor, which is very impressive. In the World Physics Year (2005) to commemorate Einstein Time, Mr. Yang to Einstein’s success attributed to his eyes and opportunities.Yang that the distinction between Lorentz and Pangkal, Einstein’s free vision (free perception, that is, long-range vision and close visit He also believes that Einstein first used the theory of modern theoretical physics – the principle of symmetrical domination interaction, with generalized coordinate invariance, coupled with the equivalent principle, to create a general theory of relativity. Mr. Yang specializes in the divorce of Einstein, the pursuit and the deep vision, that it changed the basic physical development process.Yang on Einstein in the field of theoretical physics profound impact of these evaluations, to future generations to Profoundly enlightened.Yang also studied this history from Maxwell’s original article in the article [8] of the Maxwell equation and the conceptual origin of normative theory, and carefully studied how the gauge freedom is produced and How to evolve into a symmetrical principle of supporting the particle physical standard model. In the study of science master, Yang Zhenning found that the success of the majority of European and American physicists are very aggressive (aggressive), acting to pursue one-upmanship (eager to win, for the victory and sometimes can not resort), such as Auburn Heimer, Taylor, Feynman, etc .; and he himself is more like Fermi, Zhou Guangzhao, Mills (R. E. Mills) such a gentleman of the physicist. Mr. Yang said: Europe and the United States is a great achievement of scientific achievements with most European and American scientists this aggressive personality are linked? This is a very interesting question, I call it “Yang Zhenning guess.” If linked with the education of China, in the end Confucian culture for the cultivation of innovative talents from the positive, negative, or positive and negative effects are there? These are worthy of our study. Mr. Yang believes that he has been influenced by a strong Confucian tradition. He was 12 years old in the summer vacation, in the Science Museum, his father invited Tsinghua history, a high-quality Ding Jiliang took him to learn a summer “Mencius”, although the four books by Mr. Yang only carefully studied the “Mencius”, but He believes that Confucian culture has a deep impact on their own. In his commemoration of the 60th anniversary of the theory of Yang-Mills, in 2015, Mr. Yang recalled the controversy between he and Feyman et al. On the prospect of physics in the early 1960s. He thought that it was correct to see that his judgment was correct Therefore, the correct reason is that he was “my day three provinces my mother” Confucian culture.

5 Other aspects of the contribution

is not limited to physics, Yang Zhenning return after many other areas, such as Chinese culture, international relations, Chinese development, society, art, aesthetics, archeology and many The field made a lot of public lectures, wrote a lot of articles. Limited to space and time, I only have two examples here. In 2004, Mr. Yang in the entitled “Book of Changes for the impact of Chinese culture,” the speech, that “Book of Changes” affects the way of thinking of Chinese culture, and this effect is the modern science is not in China One of the important reasons for budding. For the modern science why not in China initiation of this concern, Mr. Yang that the reasons are: First, the Chinese tradition is the WTO rather than the birth, that is more practical, do not pay attention to the abstract theoryThe fourth is the imperial examination system; the third is not attach importance to technology, that technology is “strange skills”; fourth is the Chinese culture only induction, and no deduction method, modern science needs to combine the two to develop ; Fifth is the concept of harmony between man and nature. Which the fourth and fifth with the “Book of Changes” are closely related. Mr. Yang has a unique perspective on this view, although it has led to many different opinions, but it is clear that this debate and debate as well as the deepening understanding of Chinese culture are beneficial for the development of modern Chinese science.

Mr. Yang also on the domestic academic academic integrity issues, clearly put forward their own views. June 14, 2010 at 11 o’clock in the evening, I received an email Yang Zhenning, involving “China Physics Express” a manuscript review. Tsinghua Higher Institute of a doctoral student XX to the “China Physics Express” cast an article, signed only one person. The editorial department organizes two peer-reviewed papers, one of which evaluates the paper, and the other participant asks the author to cite another three articles, and the three articles are in question There is no relationship. The author asked Mr. Yang how to deal with. Mr. Yang’s judgment is that the second reviewer asked the three articles “have absolutely nothing to do with XX’s work”, which he pointed out that the reviewers were in the interest of abuse of their privileges. We were quick to investigate and deal with it. This phenomenon is a serious academic misconduct, often in academia, many people turn a blind eye. Mr. Yang “nosy”, clearly against the academic misconduct, it is worth my admiration. After the reign of Mr. Yang Zhenning, he began the second spring of a master of theoretical physics and was very successful, making great contributions to the academic community and making an outstanding contribution to China’s technological development. We wish Mr. Yang health, look forward to celebrate Mr. Yang century birthday and tea birthday (108 years old)! References
