Beijing, 5 May (Zhongxin Net) -- Ding Zhaozhong, a well-known Chinese-American scientist, Nobel laureate in physics, and foreign academician of the Chinese Academy of Sciences, encouraged young students at the University of Chinese Academy of Sciences (UCAS) in Beijing on 19 May not to blindly follow the conclusions of experts, but to have confidence in oneself and do what he thinks is right when doing basic research.
Following a keynote speech at the High Energy Forum at the Institute of High Energy Physics of the Chinese Academy of Sciences three days ago, 3-year-old academician Ding Zhaozhong was invited to visit the Beijing Huairou Campus of the University of Science and Technology of China, and gave a keynote report on "What I Experienced in Modern Physics and My Experience" at the "Yanqi Lake Famous Lecture Hall".

Ding Zhaozhong said that the first experiment was the experiment of measuring positron and negative electron pairs in Germany (1966), and the experience was "do not blindly follow the conclusions of experts".
The second experiment was in the 20s of the 70th century, in the German DESY accelerator to do a series of experiments to measure photons and heavy photons, the experience is that "for physics experimenters, the design of precise, multiple measurement instruments is crucial". Prior to his experiments, all experiments on heavy photons had no definitive results.

The third experiment was the discovery of new matter, and experiments he led proved that heavy photons and photons are so similar that they can be converted into each other. However, "this experiment is not popular with the physics community, first, theoretical physicists believe that finding high-quality heavy photon physics is of little significance; Second, experimental physicists agree that no one can complete such a difficult experiment."
Ding Zhaozhong stressed that his experience of this experiment is that "to do basic research, you must have confidence in yourself and do what you think is right." The development of natural science is that the majority obeys the minority, do not change your interests because the majority opposes".
The fourth is the MARK-J experiment that discovered gluons, in which 27 Chinese scientists participated in the main experience of "being fully prepared for unexpected phenomena", because the original goal of the experiment was to verify quantum dynamics and electroweakness theory.
The fifth experiment, aimed at studying the origins of the universe, was the L1982 experiment on the CERN LEP colliding accelerator from 2003 to 3, a large-scale international collaboration experiment in which scientists from 19 countries participated.

The experience of this experiment is: international scientific cooperation, first, to select the most important scientific projects, arouse the greatest interest of scientists in participating countries; Second, countries that have made large contributions must be given priority recognition and internationally recognized in order to receive long-term priority support from participating governments.
The sixth experiment was the Alpha Magnetic Spectrometer (AMS) (1994-2030) on the International Space Station, and the main experience was that most of his experiments were opposed by many people on the grounds that "the experiment has no physical significance" and "the experiment is extremely difficult and impossible to succeed". However, each experiment developed its own new instrument, making the experiment successful, and the results of the experiment changed the understanding of the universe. "Over the past half century, I have collaborated with many excellent Chinese scientists, and they have made important contributions to experiments."
After the sharing of scientific experiment process and personal experience, Academician Ding Zhaozhong also interacted with the students on site. After that, Academician Li Shushen, President of UCASTech, who presided over the keynote report, presented Academician Ding Zhaozhong with a sketch portrait of Ding Zhaozhong as a commemoration.

According to news from the Institute of High Energy of the Chinese Academy of Sciences, in response to the topic of the construction of the next-generation collider, academician Ding Zhaozhong said in an interview during the high-energy forum, "The next-generation collider can discover things we can't imagine, very important, the discovery of high-energy physics has changed our basic understanding of the universe, the next step to build a large accelerator is an inevitable and very important thing, many people argue is very normal."
He stressed that international cooperation is very important, but where cooperation is more important, China should be more active in international cooperation, "arguing is normal, people are curious, what you don't do others will do, then you can only follow others", and Chinese scientists can preside over cutting-edge experimental physics.
