Nobel Prize in Physics laureate Prof. Samuel Ting has shared his story of discovering the J/psi meson, a subatomic particle that sheds new light on the theory that there existed a fourth quark, with one in a billion odds.

Ting, who discovered the particle in 1974 and received the Nobel Prize two years later, shared his story in an interview with China Media Group while attending a symposium commemorating the 50th anniversary of the discovery of the J/psi meson in Beijing on Oct. 20.

The finding marked "a pivotal moment" in the understanding of the subatomic world, which was referred to "November Revolution of the Particle Physics", said the Institute of High Energy Physics of the Chinese Academy of Sciences, host of the symposium, in a statement.

"[The experiment] was really difficult. The experimental equipment we needed should have an accuracy of as high as one part per billion. It is like, if it rains in Beijing, and there is one red raindrop among a billion fell in one second, we need to find it out. This was widely considered as impossible. Some laboratories that had particle accelerators in Europe and the United States refused to do the experiment. Finally, it was accepted by the Brookhaven National Laboratory in the United States," said Ting.

Also speaking at the symposium, Ting's friends recounted how they reacted to Ting's extraordinary finding when hearing about it.

"Was I shocked. I was wakened out of a deep sleep when Doctor Ting phoned me and said I should come to his office. He did not explain why. So, I got dressed, and I got into my car, and I drove to MIT (Massachusetts Institute of Technology) and found his office. He explained to me what he had done and showed me a picture of his experimental results. And I was absolutely flabbergasted. It was something extraordinary, very difficult to understand, and I think I said to him 'please give me a moment to think about this," said Sheldon Glashow a friend of Ting and a winner of Nobel Prize in Physics in 1979.

"I was in Italy at the time, so, the thing was not so instantaneous as Shelly, but I must say that the particle came out with some surprising qualities," said Luciano Maiani, former director-general of the European Organization for Nuclear Research.

Hailing China as a global leader in renewable energy, President of the Republic of Korea (ROK) Lee Jae Myung has expressed his strong optimism that deepening cooperation with China in the area will unlock abundant opportunities for his country.

In an interview with the China Media Group in Seoul, capital of the ROK, ahead of his upcoming state visit to China from Jan 4 to 7, Lee highlighted China's remarkable progress in clean energy and technological innovation.

He recalled his previous visits to China during his tenures as the mayor of Seongnam and later as the governor of Gyeonggi Province, when he toured Chinese cities including Chongqing and Dalian. Even then, he spoke highly of China's robust innovation capacity and commitment to high-quality development.

"I have visited China from time to time and witnessed its rapid development. It was almost a completely different country each time I went. China has rapidly transitioned to renewable energy, and it is now a global leader in the renewable energy industry, especially in solar energy," said Lee.

"China possesses truly outstanding capabilities to identify opportunities amid crises and focus national capacities on them to develop new technologies and drive industrial growth. This trend is likely to continue for quite a long period of time, and I anticipate that the cooperative relationship between the ROK and China will open up abundant opportunities for the ROK in this regard," he said.

It will be Lee's first visit to China since taking office in June 2025, and also the first visit to the country by an ROK president since 2019.

It will also marks that the two heads of state have exchanged visits within two months as Chinese President Xi Jinping paid a state visit to the ROK from Oct 30 to Nov 1, 2025.
