    Li Fuji, this is a name that has almost been forgotten by history, but it is also a name that is destined to be remembered.

    This man, who was considered a fellow villager with Sun Yuanqi, graduated from Nanyang Public School in July 1901. He was immediately sent by the school to study in Europe, where he studied mechanical engineering at Finsbury College and the University of London.  In 1906, he entered the Royal University of Bonn and studied spectroscopy under Kessel.  In 1907, he received a doctorate in advanced physics with a paper entitled "Spectroscopic Experimental Research on Lerner's Spectral Theory of Alkali Metals", becoming the first Ph.D. in physics in China's history.

    After returning to China after completing his studies, Li Fuki actively participated in the establishment of the Electrical Engineering Department of Nanyang Public School, opening up higher education in electrical engineering in China.  At that time, China was poor and weak, and it was impossible to provide the basic conditions for scientific research. As a result, his academic life was brilliant and short, and he was unable to conduct academic research in physics after returning to China.

    In 1910, he left school and worked successively in Hanyeping Company, Hankou Industrial Inspection Department, Sichuan Salt Management Bureau and other departments. He served as an engineer for large-scale projects such as Jiangnan Shipyard, Hanyang Iron Works, Pingxiang Coal Mine, and Beijing-Hankow Railway.  Contribution to the modernization of Chinese industry.  This doctor of physics is engaged in ordinary technical work every day, but he has not given up the idea of ????academic research.  In 1923, when the Beijing-Hankow Railway bridge project he was responsible for was about to be completed, he applied to his superiors for an academic study abroad trip, but was rejected.

    Li Fugu was financially strapped in his later years, so in order to delay his retirement, he had to hide his age of 5 years.  On the eve of his death, he even served as an English teacher in a middle school.  According to his children's recollections, he was in poor mental health in his later years and was taciturn and depressed after work.  It is not difficult to understand: a dignified doctor from a famous university ended up like this, but to whom should he tell the bitterness?  Thinking about it, I can only remain silent and tell myself how I feel!

    In 1947, 66-year-old Li Fuji died of illness in Zigong, Sichuan.  After his death, he was left with little money and no money for burial. With the help of his colleagues, he purchased a coffin and, in accordance with local customs, it was carried to a high mountain facing his hometown for burial.  Buried with it was the short-lived glory of the early development of Chinese physics.  After that, no one remembers it anymore.  It was not until fifty years later, after China's reform and opening up, that Sino-German exchanges became normal, that he was mentioned again by his alma mater, the University of Bonn, and became well known to Chinese academic circles.

    As China¡¯s first Ph.D. in physics, his experiences represent the glorious starting point of China¡¯s scientific development, and also reflect the suffering of Chinese scientific researchers in an era when the country was weak and the people were poor.

    When he saw Li Fuji's name, his experiences flashed through Sun Yuanqi's mind.  Logically speaking, Li Fuji should be interning or studying for a doctorate in Germany by now. How could he be in London?  With complicated emotions, Sun Yuanqi hurriedly came to the door to greet him.

    There was only one Chinese at the door, and it was undoubtedly Li Fuji.  When he heard Sun Yuanqi greeting him in Chinese, the young man quickly raised his head.  How should I put it, this young man is really not very good-looking: he has an inverted eyebrow, slender eyes, a high nose bridge, a big mouth, and a pointed chin.  But as the old saying goes: "Judg a person by his appearance, you will lose his talent." What's more, in Sun Yuanqi's view, this young man is still his senior?  Naturally, I didn¡¯t pay much attention to appearance.

    Sun Yuanqi enthusiastically invited him to the living room of the room. While pouring tea, he asked with a smile: "Brother Li, why are you in London? And do you know that I am staying here temporarily?"

    Li Fuji stood up quickly after hearing this: "Young scholars really can't bear the title of 'brother' from Mr. Sun! Mr. Sun, you'd better call me 'Zemin'!"

    "Zemin?" Sun Yuanqi thought this title was a bit weird, and after thinking about it for a while, he realized that he actually had the same name as Taizu's eldest brother and Gaozong!  Then he said, "Then don't call me 'Mr. Sun'. My name is Baixi, so just call me 'Baixi'."

    "Yes." Li Fugu took the tea cup and sat down on the sofa. "I was selected by Nanyang Public School to study in Europe in 1901 for four years. I was also accompanied by Zeng Zongjian and Hu Zhenping who studied politics and business.  Zhao Xingchang. We first entered King's College to study English, and then we parted ways. I went to Finsbury College to study mechanical engineering, then to the London Institute of Mechanical Engineers for a year as an intern, and now I'm studying mechanical engineering at the University of London, and I'm about to graduate.  I just happened to see a poster posted by the school, saying that you will have an academic report in the near future. I asked the school and the Royal Society to find out your address. I am really sorry for interrupting your work by visiting this time!"

    Sun Yuanqi didn't take it seriously and waved his hand: "It's okay, it's okay. I'm just busy, nothing serious. So, do you still plan to continue your studies?"

    Li Fugu nodded: "Yes, I think there is still a lot to learn, so I want to apply for a two-year extension to stay in Europe to continue studying. Now I am waiting for news from Mr. Sheng, the Superintendent of Nanyang Public School, and Mr. Zhang, the Promoter and Prime Minister.  , I wonder how they will reply!?This is pure talk. The orthodox scientists sitting in the audience started to commotion when they heard this. If British customs did not require them to maintain a gentlemanly demeanor at all times, they would have left the stage or asked questions to refute.

    Sun Yuanqi finally threw out his bait: "Based on the two conjectures, we can infer that if there is antimatter in the universe, then there should be certain antiparticles in cosmic rays that are opposite to the known particles on the earth. Can this inference be used experimentally?  How about proving it? I think it is absolutely possible! To this end, I designed an experimental plan on the ship from Boston to London."

    The plan Sun Yuanqi mentioned is the device used by Anderson to discover positrons in 1932: first place the cloud chamber in a magnetic field, and the particles entering the cloud chamber will separate according to their charged properties; several metal plates are installed in the cloud chamber  , let the particles pass through the metal plate, and then distinguish its energy.  After a long period of extensive observation, a peculiar track can be found in the photo. It is similar to the track of electrons, but has the opposite direction.  This is the positron.

    After Sun Yuanqi finished speaking, the audience fell silent.

    In the eyes of these scientists, Sun Yuanqi is simply talking nonsense and what he says is totally useless.  But to refute, this speech is full of conjectures and cannot be proven with existing knowledge.  Fortunately, Sun Yuanqi came up with a plan that can be quickly verified: If the experiment fails, doesn't it mean that he is talking nonsense?  If you can personally expose the delusions of this so-called "greatest young scientist at the beginning of this century" and embarrass him, it will be a very honorable thing, right?

    Therefore, many scientists in the audience were eager to try it, and they only waited for the ceremony to end before returning to the laboratory to prepare.  (To be continued.
