Yang Zhenning is a respected scientist. His achievements in science and contribution to the world are enormous. There is no doubt that China's blood runs through him, and it is the pride of the Chinese nation that he won the Nobel Prize.
He is the greatest physicist still alive in the world, and the international scientific and technological community even lists him as a scientific giant comparable to Einstein and Newton. Yang Zhenning's scientific research achievements are not well known to the world, because they are so profound that their value exceeds a Nobel Prize in physics. Then there was a major breakthrough in elementary particles. An all-rounder who has made outstanding contributions in different physical fields such as statistical physics and condensed matter physics. Is a first-class master of physics.
1954, the "Young-Mills Equation" came out. A year later, his "parity conservation law" and Li Zhengdao won the Nobel Prize in physics, and more than 10 Nobel Prizes were all related to Yang Zhenning's research results. Such an achievement is amazing.
What really makes Yang Zhenning the Beidou of Mount Tai is his theory of Yang Grinding, which frames the progress and research direction in the current and future physics field. Let's just say that his theory says that high-end basic theory is the expansion direction of high-end physics, and his theory guides the definition of the direction of physics research at present and in the next few decades or even hundreds of years. That is to say, at present, many physics studies are carried out on his basis, and the progress of others' physics research is equivalent to finding progress on Yang Zhenning's shoulder.
At present, six physicists have studied Yang Zhenning's high-end basic theory and won the Nobel Prize, which also proves that Yang Zhenning's high-end basic theory is actually completely correct. I believe this is just the beginning, and there will be more discoveries in the future. This foundation is the development direction of physics in the next few decades, and the development direction of modern science and technology is based on the achievements of physics research progress. It can also be said that the development of modern science was promoted by Yang Zhenning, Einstein, Newton and those physical contributors who left their names in history.
Professor Yang Zhenning has also made great contributions to promoting the scientific development of the motherland. As early as the Sino-American relationship was warm, he returned to China to give lectures, bringing frontier knowledge to the motherland and improving the level of physics research. He also founded Nankai Mathematical Physics Laboratory and Yilida Youth Invention Award, which promoted the development of science and education in China.
Especially after Yang Zhenning returned to China, he volunteered to set up more than 60 physics laboratories for the country. No one can match such a simple contribution. These more than 60 scientific laboratories have laid a solid foundation for the high-quality development of China.
Yang Zhenning celebrated his centenary birthday. How big is his scientific contribution?
Yang Zhenning's scientific achievements are enormous, and his contribution to society is immeasurable, mainly in the fields of particle physics, gauge field theory, statistical mechanics and gluing platform physics. For example, parity is not conserved under the weak interaction in the field of particle physics, which was discovered by him and Li Zhengdao. He won the Nobel Prize in Physics from 65438 to 0957. The most important achievement in gauge field theory is Yang-Mills gauge field theory.
What are Yang Zhenning's achievements and contributions?
1, phase transition theory
Statistical mechanics is one of the main research directions of Yang Zhenning. His characteristic in statistical mechanics is to strictly solve and analyze the general model rooted in physical reality, so as to grasp the essence and essence of the problem.
From 65438 to 0952, Yang Zhenning and his collaborators published three important papers on phase transition. The first article was written by him independently the year before last.
In 1952, Yang Zhenning also finished and published two articles in cooperation with Li Zhengdao.
The climax of these two papers is the unit circle theorem in the second paper, which points out that the zero point of the giant partition function of the lattice gas model attracting interaction lies on the unit circle on the complex plane.
2. Boson many-body problem
Due to his interest in liquid helium superfluid, Yang Zhenning and his collaborators published or completed a series around 1957.
First, he published two papers with Huang and Luttinger, and applied the pseudopotential method to this field. Well written
The most surprising energy correction they got was the famous square root correction term, but it could not be verified by experiments at that time. However, with the development of cold atomic physics, this correction term has been confirmed by experiments.
3. Young-Baxter equation
In 1960s, Yang Zhenning found the strict solution of quantum statistical model by trying to find off-diagonal long program model. 1967, it was found that the fermion quantum many-body problem in the repulsive potential of 1 dimensional δ function could be transformed into a matrix equation, which was later called Yang-Baxter equation.
In 1967, Yang Zhenning also wrote an article published in the following year, further discussing the problem of S matrix. Later, it was found that Yang -—Baxter equation is an extremely important equation in mathematics and physics, which is closely related to kink theory, braid group, Hopf algebra and even string theory.
The 1 dimensional fermion problem discussed by Yang Zhenning is very important in the experimental study of cold atoms. The nested Bethe hypothesis method he invented in this paper was used by Lieb and Wu Fayue to solve the 1 dimensional Hubbard model the following year. Hubbard model later became the basis of many theoretical studies on high temperature superconductivity.
4. Theoretical explanation of superconducting magnetic ionization.
196 1 year, through close communication with Fei Zhengqing experimental group, Yang Zhenning and byers theoretically explained the superconducting magnetic ionization discovered by the experimental group, proved that electron pairing can lead to observed phenomena, and clarified that it is unnecessary to introduce new ones.
In this work, Yang Zhenning and byers applied gauge transformation technique to condensed matter system. Related physics and methods were later widely used in the study of superconductivity, superfluidity and quantum Hall effect.
5. Off-diagonal long program
1962, Yang Zhenning put forward the concept of "off-diagonal long program", which described the essence of superfluidity and superconductivity in a unified way, and deeply discussed the root of magnetic flux ionization.
This is a key concept of contemporary condensed matter physics. From 1989 to 1990, Yang Zhenning found the eigenstate with off-diagonal long program in the Hubbard model closely related to HTS, and found its SO symmetry with Zhang Shousheng.
What is Yang Zhenning's scientific contribution?
On the afternoon of September 22nd, the celebration of Yang Zhenning's centenary birthday was held in Tsinghua University.
1. Introduce Yang Zhenning briefly.
Many people only know that Yang Zhenning won the Nobel Prize in Literature, but they know nothing about other information. Yang Zhenning, 1922, born in Hefei, Anhui Province, is a famous physicist, dean of the Institute of Advanced Studies of Tsinghua University and academician of China Academy of Sciences. Yang Zhenning won the Nobel Prize in Physics in 1957. Some people say that Yang Zhenning is a Chinese American scientist. Indeed, Yang Zhenning became an American citizen in 1964, but this did not prevent Yang Zhenning from making great contributions to physics. Yang Zhenning is also an academician of China Academy of Sciences. He devoted his whole life to physics, and physics also gave him more honors.
Two. Yang Zhenning's scientific contribution.
Yang Zhenning won the Nobel Prize in Physics for his achievements in particle physics. In fact, Yang Zhenning has made many scientific contributions, such as the theoretical explanation of superconducting magnetic ionization, including
Three. Yang Zhenning's life outside science.
Even among famous scientists, they are still ordinary people. Apart from her greatest contribution to science, Yang Zhenning talked about the story of her and his youngest wife, Weng Fan. In 2004, 82-year-old Yang Zhenning and 28-year-old Weng Fan registered their marriage and were called "old love" by the public. Despite the opposition from the outside world, they resolutely stayed together. Their combination did not affect Yang Zhenning's career development, but took better care of Yang Zhenning's health and let Yang Zhenning continue to make his own contribution to science.
What award did Yang Zhenning win?
1957, Yang Zhenning and Li Zhengdao won the Nobel Prize in physics for putting forward the theory of parity non-conservation.
Since then, he has also won Fermi Award, Runford Award, Oppenheimer Memorial Award, National Science Medal Award, Moscow University Award, Benjamin Franklin Award, Bauer Award and China International Science and Technology Cooperation Award;
Russian Bogoliubov Award, Onsager Award, Papal Academic Award, King Faisal International Science Award, Lifetime Achievement Award, Marcel Grossman Award.
On the evening of September 2, 20 19, the awarding ceremony of the 20 19 Qiushi Award, hosted by the Hong Kong Qiushi Science and Technology Foundation, was held in Tsinghua University. Yang Zhenning, winner of the Nobel Prize in Physics, was awarded the "Seeking Lifelong Achievement Award" and became the second scientist to win this honor.
Personality influence
1On May 25th, 997, China Academy of Sciences and Jiangsu Provincial People's Government announced that the International Asteroid Center discovered the Purple Mountain Observatory of China Academy of Sciences at 10/975165438+on October 26th, and the asteroid with the international number of 342 1 was officially named as.
1999 In May, the State University of New York at Stony Brook named the Institute of Theoretical Physics "Yang Zhenning Institute of Theoretical Physics".
On April 2 1 2004, Tsinghua University established "Yang Zhenning Lecture Fund" and invited internationally renowned professors and outstanding young scholars to Tsinghua University Advanced Research Center to devote themselves to scientific research.
On1October 29th, 2008, 165438, Yang Zhenning was elected as "the most influential overseas expert in China in the 30 years of reform and opening up".
From June 5438 to February 65438, 2020, he was selected as one of the top 500 brand figures in China in 2020, ranking 49.
On 20021May 14, Mr. Yang Zhenning donated Tsinghua University and the unveiling ceremony of "Yang Zhenning Reference Room" was held in the North Library of Tsinghua University Library.
What contribution did Yang Zhenning make?
As a master of physics in today's world, Yang Zhenning has made great contributions to theoretical physics, which can be said to be the first in the world. Deng Jiaxian, a famous nuclear physicist and a scientist with two bombs and one satellite, spoke highly of Yang Zhenning's contribution to physics.
Yang Zhenning's greatest contribution was to put forward the famous Yang-Mills theory, which was praised by Deng Jiaxian as comparable to Newton's law of universal gravitation. Young-Mills theory is the cornerstone of the standard model of particle physics, which is the extreme of current physics, and it unifies the other three basic natural forces except gravity. If the future standard model can unify gravity, it will highlight the position of Young-Mills theory in physics.
Yang Zhenning's second contribution is to put forward the principle of parity non-conservation. Although the significance of this work is not as far-reaching as that of Yang-Mills theory, he won the Nobel Prize in Physics. Just like Einstein, his greatest achievement in physics is to put forward the general theory of relativity, but the reason why he won the Nobel Prize is related to quantum physics.
Yang Zhenning's theoretical physics contributions also include Yang-Baxter equation, off-diagonal long program, Li-Yang phase transition, etc., which are also master contributions.
Many people criticized Yang Zhenning for not going back to serve the motherland like Deng Jiaxian and Qian Xuesen shortly after the founding of New China, but the problem is that Yang Zhenning, who was doing theoretical physics at that time, didn't make sense. What was needed in those days was a physicist who was biased towards application. Later, after returning to China, Yang Zhenning took an active part in education, trained many talents for China and persuaded many overseas talents. Therefore, Yang Zhenning deserves people's respect, and we should not talk about his private affairs.
Mr. Yang's achievement belongs to Baidu, and he can do it himself. Say something else here.
1, the difference between theoretical physics and applied technology. Theoretical physics studies the nature of cosmic matter and answers why things work like this. For example, Newton's classical mechanics explains why apples fall from trees, that is, the gravity extended by free fall. Maxwell's electromagnetism solved the problems of what the earth's magnetic field is and how electric waves propagate in it. Rutherford's nuclear physics has solved what is nuclear matter and what is half-life. Einstein's theory of relativity solved the conversion between mass and energy. What is applied technology? Today, almost all mechanical movements, such as engines, are based on the application technology of Newton's classical mechanics, and radio communication, such as mobile satellite long-wave and short-wave radio stations, are based on the application technology of electromagnetism. Medical ct machines and seamless steel pipe flaw detection are based on Rutherford's nuclear physics, and atomic bombs and hydrogen bombs in nuclear power plants are based on Einstein's theory of relativity. Mr. Yang is a theoretical physicist, that is to say, he actually played the roles of Newton, Maxwell and Einstein. As we all know, the steam engine was invented by Watt, and Maxwell didn't make the first radio communication. The atomic bomb was first made in Oppenheimer, and the atomic bomb in China was made by Qian Deng and others. So don't think that people who invent things are awesome, they just stand on the shoulders of giants and take a look.
2. Why didn't Yang return to China that year? Objectively speaking, there are several reasons. First, theoretical physics burns money, and the European Collider is used to verify elementary particles. In order to prove dark matter, the United States launched a satellite to capture and observe it decades ago. But these things show that it is unrealistic whether it is civilian or military. Theoretical circles say that mathematics has surpassed the science and technology of this era for 500 years, physics has surpassed 100 years, and biochemistry conforms to today's science and technology. Therefore, people who won the Nobel Prize in Physics hardly understand what the scientific significance is, but the biochemical prize can still understand what some of them are useful. On the other hand, at that time, the new China was poor, unable to support theoretical physics research, and didn't even have a liquid separator, let alone large-scale experimental equipment. Moreover, at that time, the country did not need to conduct theoretical physics research, and the mature theories in the world did not learn well. It is unrealistic to want to engage in new theories, just as it is unrealistic to have not finished studying for a doctorate in primary school. Moreover, theoretical physics has no national boundaries and no technical barriers. Theoretically, the whole world is enjoying it, and it is still enjoying it now. Second, during the Cultural Revolution, immortals with foreign backgrounds, including those who had been abroad, senior intellectuals and Kuomintang background, were also disabled. Unfortunately, Mr. Yang took them all away, while Du was a senior overseas intellectual and father-in-law. Moreover, as I said before, it is useless for those who engage in theoretical physics to return to China, and they don't have the amulet of the atomic bomb like Qian Deng. It is almost certain that Mr. Yang will not live until he returns to China.
3. Yang's affair with. The gossip content is Baidu itself. What I want to say here is that the Nobel Prize between Mr. Yang and Mr. Yang is the peak of his life for me, but it is only a negligible achievement for Mr. Yang. The Yang-Mills equation behind Mr. Yang is a great achievement of Yang Zui, and then at least seven Nobel Prize in physics were awarded to the researchers of the Yang-Mills equation. There is a good saying that some people regard the Nobel Prize as the glory of their lives, while others are proud to award it to him. This is also the reason why the Nobel Prize in Physics racked its brains to award Einstein. In other words, if Mr. Yang didn't win the Nobel Prize at the beginning, so many people who have studied his theory have won the Nobel Prize now, and the Nobel Prize should be reserved for Mr. Yang, otherwise the person who won the Nobel Prize because of Mr. Yang will come to power.
4. Mr. Yang's marriage. The Weng family is a well-known family and is not short of money, so the argument of marrying Mr. Yang for money is not established. Besides, when I met Mr. Yang, Ms. Du was still alive and knew him. After marrying someone else, the marriage was unhappy and divorced, and Ms. Du also died at that time, so Mr. Yang had no emotional contact with Ms. Du when she was alive. The marriage between Mr. Yang and Mr. Yang, Weng Fan's personal worship of Mr. Yang and his active pursuit of Mr. Yang are also very important reasons. When I was young, I was very similar to Du.
Yang Zhenning appeared on the earth to prove the existence of' God'!
Yang Zhenning is the top 15 physicist in the world. Together with Feynman and Landau, he laid the silver age of physics in the 20th century. He is the most outstanding designer of physics in the 20th century after Einstein and Dirac!
Yang Zhenning is a theoretical physicist. He made extensive contributions to theoretical physics. He made many important contributions in the fields of statistical mechanics, condensed matter physics, particle physics, field theory and so on, among which particle physics made the greatest contribution.
Yang Zhenning has made many contributions to the world. No matter which achievement, his contribution to the world is enormous!
Yang Zhenning's academic achievements in physics are breakthrough, pioneering and leading!
In particular, in cooperation with Li Zhengdao, he put forward the theory of weak interaction parity non-conservation in 1956, which won them the Nobel Prize in physics in 1957!
The theory of parity non-conservation of weak interaction is of epoch-making significance, whether from the microscopic point of view of physics or from the macroscopic point of view of the universe!
Yang Zhenning is the favorite pride of China people!
His great contribution to the world and China proves his extraordinary and greatness! He is great in history! He is unprecedented great!
Yang Zhenning, he is indeed the existence of "God"!
1957, young Yang Zhenning and Li Zhengdao won the Nobel Prize as physicists, because they proposed that parity is not conserved, which was previously considered to be conserved. This contribution is not Yang Zhenning's greatest contribution to physics. The greatest contribution should be Yang-Mills gauge field theory. As far as I know, seven people won the Nobel Prize for discovering the particles predicted by this theory according to this theory. In addition, there is a Yang-Baxter equation second only to this theory.
Yang Zhenning has made world-class outstanding contributions in condensed matter physics, statistical mechanics, field theory and particle physics, which is a well-known achievement of the 13 Nobel Prize. Combining different literatures
Many people will think that Yang Zhenning did not return to China at that time, and even point out that Yang Zhenning married Weng Fan in 2004, which is the focus of discussion. In fact, what reason do we have to evaluate other people's marriages? Who are you?
Let's talk about why Yang Zhenning didn't return to China at that time. Yang Zhenning is engaged in basic scientific research beneficial to all mankind. This is not applied physics, so it has little influence on the real science and technology at that time. For example, Einstein's general theory of relativity is still being tested.
197 1 "Protection of Fishing" Movement,197165438+1On October 29th, 500 international students from nine universities in Jinshan Bay, California spontaneously gathered in San Francisco to set off a demonstration to protect fishing. During the demonstration, some foreign students were attacked by unknown elements, and patriotism sometimes. Yang Zhenning has made great contributions to the sport of protecting fishing, giving speeches in various schools in the United States, arousing the patriotic thoughts of overseas students, and explaining the fact that Diaoyu Island is China's inherent territory at the hearing of the US Senate.
Yang Zhenning also actively participated in the knowledge education in China, founded the All-American Chinese Association, built a bridge for academic exchanges between China and the United States, established dozens of laboratories in China, and donated more than $ 1000 million to higher knowledge education. Wang Dazhong, former president of Tsinghua University and academician of Chinese Academy of Sciences, once commented on Yang Zhenning, "Without Yang Zhenning, there would be no Tsinghua Physics Department today!"
Time is limited, so I can't go into details. Lao Yang's contribution is more than that. Some comments on the Internet are really sorry for Lao Yang.
What contribution did Yang Zhenning make?
Perhaps it can be said that Yang Zhenning is the greatest scientist still alive, which should be worthy of the name, because almost all the greatest scientists who competed with him and ranked first have passed away!
Of course, the ranking of the greatest scientists is elected by voting. If you have different opinions, you can leave a message! But Einstein ranks first, so you should have no problem! Yang Zhenning certainly can't rank among the top ten, but it is generally acknowledged that he should be between 15-20!
So what contribution did Yang Zhenning make? To be among the top 20 greatest scientists.
One is to discover parity non-conservation theorem with Li Zhengdao, and 1957 won the Nobel Prize in physics. Of course, we should not forget Ms. Wu Jianxiong, who did a wonderful experiment for this!
This painting skillfully combines the relationship between the three!
The second is Yang-Mills gauge field theory, which is a solid step towards the unity of mankind. You may think that Yang Zhenning has made achievements in cooperation with others. In fact, everyone has made unimaginable efforts in this process, and the Nobel Committee has also recognized its outstanding contribution!
In addition, it is worth mentioning that more than a dozen other scientists won the Nobel Prize for their theoretical research on gauge field, which opened a new discipline, even an era!
In addition, Yang Zhenning has made outstanding contributions to statistical mechanics, field theory, condensed matter physics and particle physics. From these aspects, Yang Zhenning is truly the greatest scientist! Many friends have been criticizing him for not returning to China in the early days, but in fact, Yang Zhenning, who is engaged in theoretical physics research, does have great limitations in returning to China, because a blank new China cannot provide him with various environments! Later, after returning to China, he engaged in education and trained many talents, and many scientists returned to China because of his persuasion!
Basically, we can think that Yang Zhenning should not be blamed, but he must be sure of his great contribution to the scientific community and even the world!
Yang Zhenning's greatest contribution at present is also well-known direct service to the public, that is, he can bring a topic to the sprayers and make them happier ~ ~ After all, a brainless life is boring ~
Yang Zhenning, a master of physics, is the first person in theoretical physics in the world today. The main achievements are: parity non-conservation principle, Young-Mills theory, theoretical explanation of superconducting magnetic flux quantization, Lee-Young phase transition, Young-Baxter equation and so on. Simply say two.
The principle of parity non-conservation was put forward by Yang Zhenning and Li Zhengdao in 1956, and Wu Jianxiong verified this principle with cobalt 60. The principle of parity non-conservation is a familiar and unfamiliar term in China. It is the reason why China won the Nobel Prize for the first time, but we seldom know its significance. We know that our universe is full of symmetry from appearance to internal relations. For example, a circle, an atom, a snowflake, a leaf, a person and so on are all symmetrical objects. In terms of physical laws, momentum conservation, energy conservation and so on are all manifestations of symmetry, so before the principle of parity non-conservation was discovered, most scientists thought that the world was symmetrical, that is to say, parity conservation was correct.
1954, Yang Zhenning and Mills put forward Yang-Mills theory, and Yang-Mills equation, Maxwell equation and Einstein gravitational field equation became the three most important equations in modern physics. We know that the ultimate goal in today's physics field is to unify the four basic forces, namely, weak interaction force, strong interaction force, electromagnetic force and universal gravitation. Based on Young-Mills theory, physicists can directly unify the other three forces except gravity, which is equivalent to three quarters of the ultimate goal of physics. The intermediate boson predicted by Young-Mills theory has been found, which is a vector particle that propagates weak interaction force. Young-Mills theory also provides a direction for the study of hadrons, which are the basic particles that spread strong interaction forces. Just like Einstein, although he won the Nobel Prize for the light quantum hypothesis, his most important scientific contribution is the theory of relativity. Although he won the Nobel Prize for parity non-conservation, his most important contribution is Yang-Mills theory.
There are many online now.
Thank you for browsing. I'm Zou Dou. Welcome to pay attention.
At the age of eighty-two, Yang Zhenning married 28-year-old Weng Fan, and then Yang Zhenning's granddaughter married Weng Fan's father. What affects me the most is what they call each other.
Yang Zhenning is the most outstanding scientist at present, and his contribution is comparable to that of Einstein and Newton. You are always staring at his marriage. He's just old and needs someone to take care of him. What you see now is Hawking, a disabled person of Grade 9, and several wives. Hawking is not qualified to put shoes on Yang Zhenning.
Yang has never put forward any theory independently! Always touch other people's light! Other people's efforts also belong to a name!
