On this day 127 years ago, on July 16, 1898 (May 28, 1898), Ye Qisun, a great master of Chinese physics, was born. "Some people suspect that the Chinese nation is not suitable for studying science, and I think these arguments are groundless. China has recently realized the importance of studying science. We have not undergone long-term experiments, and we cannot say that we lack the ability to study science. We can only hope that everyone will work together to study and research, and then make a statement in fifty years. You must know that a nation without natural science cannot stand on its feet in modern times." - Ye Qisun, the father of Chinese physics, Ye Qisun (1898.7.16~ 1977.1.13) from Shanghai. An outstanding Chinese physicist and educator, a generation of grandmasters in Chinese physics, and a pioneer in the history of Chinese science. He graduated from Tsinghua School in 1918 and immediately went to the United States for further study. He received a Bachelor of Science degree from the University of Chicago in 1920 and a Doctor of Philosophy degree from Harvard University in 1923. After returning to China in 1924, he served as an associate professor at National Southeast University (renamed Nanjing University in 1949), a professor at Tsinghua University, the head of the Department of Physics and the dean of the School of Science. He was also one of the founders of the Chinese Physical Society. He served as the first and second vice presidents of the Chinese Physical Society, and the president in 1936. One of the four philosophers in the 100-year history of Tsinghua University. The other three are Pan Guangdan, Chen Yinke, and Mei Yiqi. When I came back from the plane to read a book and saw this photo, I was stunned for a while. I didn't know this person, but I thought it was rare to see such a quiet and determined face. It was so beautiful. After reading it, I realized that those of us who know Li Zhengdao, Qian Xuesen, Qian Sanqiang, Wang Ganchang... should have known him - --- he was their teacher. When Li Zhengdao was a sophomore, he made an exception and was sent to the United States. At the time, Li Zhengdao was only 19 years old. He wore shorts to apply for a passport. The office staff did not believe "how could it be a child?" Li Zhengdao later said "he decided my fate." Hua Luogeng is a junior high school student. He let him work in the Department of Mathematics at Tsinghua University and sent him to England for further study. Hua Luogeng said that "he loved and cared for him endlessly all my life." It was the era of war, but the important scientific development depended on these people at that time. It was the peaches and plums he planted on the scorched earth at that time ¡£--------- But why didn't I know him? I looked for his information little by little in the middle of the night. He was born in Shanghai, and his father was an old-fashioned scholar, so he read a subset of scriptures and history from an early age. In his childhood, he had asked himself to practice self-reflection in the way of a gentleman's "caution and independence", and he also wrote in his pen about the "separation of seats due to small mistakes" with friends: "I was angry for a while, and I still have hidden pain when I think about it so far. In 1915, when he was a student at Tsinghua University, he established the first student group in the history of Tsinghua University, the Science Society. Scientific reports were held every two weeks, and they were given in turn. "The range is extremely wide, such as speeches in heaven, apple seed selection, coal, wireless telegraph equipment, surveying and mapping methods, force, waste utilization, etc." He was only seventeen years old at the time, and the membership rules he drew up were: (1) do not talk about religion, (2) do not talk about politics, (3) do not stay far away, (4) do not talk about high, (5) study hard, and (6) do things hard. That green vitality is full of the fledgling vitality of Chinese universities. 3. In 1918, he studied in the United States and later studied for a doctorate at Harvard, under the supervision of the Nobel Prize winner in physics, Bridgman. His first research project was to accurately determine the fundamental action quantum H value using the X-ray shortwave limit method. The experimental results were published in the Proceedings of the Academy of Sciences and the Journal of the Optical Society, and were soon recognized by the international scientific community as the most accurate H value at that time. This value was used by the international physics community for 16 years. He was 23 years old that year. 4. He returned to teach at Tsinghua University at the age of 27, and knew very well what he was facing. His students recalled that "there were four people in the first class of physics, only two people in the second class, and only one person in the third class. From the first grade to the second grade, to the third grade, he taught all the classes by himself, not because he wanted to be alone. He wanted to invite people to come, but if they didn't come, they couldn't be invited. "He no longer asked for harvest, but only asked for hard work. He was also famous for his strict teaching, and his class gave Li Zhengdao a score of 83. He allowed the student not to listen to his class" because your reference book is better than mine, "but" your experiment is not serious, and 25 points will be deducted. "Years after his death, relatives found that he had kept the three answer sheets from that year, written on yellowed Kunming soil paper. When I read the historical materials, I will have a feeling - in the turbulent land of China, as long as I give them a little space, what can Chinese intellectuals plant in the cracks of the stone? He is the director of the Department of Physics of Tsinghua University, which is actually a sacrifice for himself, which is equivalent to giving up his professional research to do administrative work. Because he made it a top priority to hire first-class scholars to teach at Tsinghua University. From 1926 to 1937, he successively hired Xiong Qinglai, Wu Youxun, Sapendong, Zhang Zigao, Huang Ziqing, Zhou Peiyuan, Zhao Zhongyao, Ren Zhigong and other scholars for the Department of Physics and the School of Science. Wu Youxun was just an ordinary teacher who had just arrived at the school, and his qualifications were not as old as him. He set Wu Youxun's salary higher than his own. In 1934, he introduced Wu Youxun to succeed him as the head of his physics department. Four years later, he urged Wu Youxun to succeed him as the dean of his science college, when he was in his prime. When Feng Bingquan graduated, he said to them: "I'm not good at teaching, so I'm sorry for you. But one thing that is worthy of you is that all the gentlemen I hired to teach you are better than me." He not only wanted to plant, but also to raise soil. In 1929, he established Tsinghua Science College, which included six departments of arithmetic, physics, chemistry, biology, psychology, and earth. He said that wherever talents are produced, it must be the place where the scientific culture is most prevalent, the scientific soil is most fertile, and the scientific atmosphere is the strongest. For example, Göttingen in Europe, Munich, and Chicago in the United States. China's scientific research has been stagnant for thousands of years, and for the first time it has this hot-hot ambition: "In addition to cultivating scientific and practical talents, it also seeks to establish a research center for science, so as to seek China's academic independence." The six little shoots came from under the stone. Tsinghua's school history records that "In the early years, Tsinghua was subordinate to the Beiyang government, and implemented the personal dictatorship of the principals. The principals were mostly officials and politicians, who had little knowledge and did not understand management. Moreover, the turnover of principals was very frequent, which seriously affected the normal progress of education and teaching." In 1927, Tsinghua established a professorial council and a senatorial council. The professorial council consisted of professors from various departments, and the members of the professorial council voted for the chairpeople of each department. The senatorial council consisted of senators, and the senators were professors recommended by each department. The next year, he was elected a senatorial council member, when he was under 30 years old. This reform was promoted by the "young strong faction". Later researchers of the history of Tsinghua University said that "professors governing the school, to put it bluntly, refused laymen to enter the school management, and expelled those who did not understand science, academics, and education. It prevented the erosion and destruction of university education by the bureaucratic system under the old system. At the same time, it decentralized the administrative power of the school and formed a mechanism of checks and balances. It played an indelible role in ensuring the democratic running and democratic management of institutions of higher learning, ensuring the independence of the school, the freedom of thought of scholars and students, and stimulating creativity." For two years from 1929 to 1931, Tsinghua University did not have an officially appointed president, and the professors' association governed the school purely on behalf of all professors. The declaration of the professors' meeting at that time was: "Tsinghua University is not an administrative organ, and the school can completely go beyond the political tide and carry out independently." Qian Xuesen was his student. After understanding this history, one would know that Qian Xuesen's question before his death not only pointed to the future, but also a hard look back. Seven He never married, but he was close to his students. One of them was called Xiong Dazhen, which was the deepest relationship in his life. Photos of Xiong at that time can be found online, full of vitality, and can be leaped out of the paper. They almost depended on each other for a few years. In 1938, Xiong suddenly told him that he was going to Jizhong to fight against the Japanese. He knew that the student did not rely on people he knew well in Hebei and had no political experience, but the national disaster was imminent, so he could only send him there. After the bear left, he had "for about ten days, his thoughts were depressed and his mind was at a loss. Every day, he could only sit in the meditation room, read some English novels, and seek to calm down." The only consolation he could give was that he was able to help his students search for some detonators, explosives, and other military supplies in the back. When I read this book, I learned that the TNT medicinal mines that once blew up the front of the Japanese locomotive were made by these students, not by the farmer's land method in the movie "Mine Warfare" we watched as children. During the war, Xiong Dazhen was suspected of being a traitor, secretly arrested, and was stoned to death during his escort without investigation and verification, and without any legal procedures. Nearly 100 intellectuals who came from Pingjin to Jizhong to participate in the anti-Japanese war were implicated. After that, because there was no more scientific and technological strength to make their own ammunition, the soldiers could only fight with empty guns and stuff straw in bullet bags. On June 23, 1947, he wrote in his diary, "Today is the Dragon Boat Festival of the old calendar. Every Dragon Boat Festival, I think of Da Zhen. Nine years ago, on the Dragon Boat Festival, he returned to Tianjin from the mainland, which was a surprise. Who knows how sad things will be in the future. In recent days, reading" The Song of Taoist White Stone ", I saw his sentence" Five Days of Desolate Heart ", which made me more sad. After 1949, he was still the leader of Tsinghua University for a period of time until 1951. In 1968, at the age of 70, he was arrested on suspicion of "the Kuomintang C.C. Secret Service Group" because of Xiong Dazhen's incident. He spent a year and a half in prison. Huang Yanfu, who has read the interrogation records, said that all he said was "I am a scientist, I am honest, and I do not tell lies." After that, he was quarantined and censored by the Red Guards. He had hallucinations and thought that a radio station was monitoring him. "Every move was reflected. He took a sip of tea, and the radio station said that he was drinking tea wrong. When he walked out the door, the radio station told him to go back immediately." His nephew looked at him, "very sad", and said "you are studying physics, you know that radio waves can't penetrate walls, there is no such thing at all, it is an illusion". He said "yes, you are deaf and can't hear". Then he went to prison again, and when he came out, he was seriously ill, incontinent, his legs were swollen and it was difficult to stand, and his whole body was arched at ninety degrees. Nine At that time, many people in the Zhongguancun area saw him. He wore a pair of torn cotton shoes with a broken head, and sometimes went to a small stall and asked the stall owner for a small apple or two, chewing as he walked. If he met someone who looked like a student, he reached out and said, "You have money to give me a few". All he asked for was three or five yuan. Later, he had gradually regained some sanity, and once Qian Sanqiang met him on the horse road in Zhongguancun, "As soon as I saw the teacher, I immediately ran up to greet the gentleman and expressed my concern. As soon as the gentleman saw him coming, he immediately said, leave me quickly, get away, and when you see me in the future, don't pay attention to me again, and stay away from me." Qian Sanqiang was the deputy minister of the Second Ministry of Machinery at the time, in charge of the atomic bomb project. His students knew his intentions well. "He knew such an important job, and he was most afraid of interacting with those who were politically problematic. He was afraid that Qian Sanqiang would suffer some misfortune as a result. "Ten or two years later, Zhang Zhixiang, a teacher at Peking University, found him on his bicycle in an apartment off campus." He didn't know me anymore, "Zhang Zhixiang said." I said I was Zhang Zhixiang, and he said oh oh, sit down. He sat on the rattan chair and showed me that his legs, both legs were so swollen that he couldn't walk. He didn't complain, he was very calm. But he didn't look like a human anymore. I didn't have much to say. I said sir, take care, I just, I just... "He burst into tears. I left and never saw him again." His nephew said he had never told anyone about his misery. "He felt as if there were many wrongs in the world and in history, and there was no need to lament about his life." He just often sat in an old rattan chair, reading some classical poetry or history books to pass the time. He died on Jan. 13, 1977. At the end of his life, when Qian Linzhao went to see him, he took out "The Book of Song" and flipped to a passage from Fan Ye's "The Book of Prison and Nephew and Nephew": "I have quarreled with the sky, but I can't say it again. You should all discard him as a sinner, but you are already in your arms, and you can still find it. As for whether you can understand it or not, you may not know." I repeated these few words of his, "I am mad and defy the sky, how can I say it again, you should all discard it as a sinner..." Until the 1980s, after being rehabilitated, when Tsinghua wanted to make a statue of him, there were still people who said, "If you want to make a statue of this man, I will pee on it." "However, I have been pregnant for a lifetime, and it should still be found..." In 1929, he said in an article called "The Past, Present and Future of Chinese Scientific Circles." "Some people suspect that the Chinese nation is not suitable for the study of science. I think these arguments are groundless. China has recently realized the importance of studying science. We have not yet undergone long-term experiments, and it cannot be said that we lack the ability to study science. I only hope that everyone will work together to study and research, and then make a conclusion in fifty years. You must know that a nation without natural science cannot stand on its feet in modern times. "Eighty years have passed, and everything he planted in the blank has allowed future generations like me to live in a world with thick shades, but I only know the existence of Mr. Ye Qisun today." As for whether you can understand it or not, you may not know it... "In this photo, he looked at me so frankly and gently, without asking for understanding or reproaching, but such questions have been heavily placed in people's hearts ever since. Afterwards, the whole country celebrated and welcomed you into the city, thinking that there would be a" bright day "from now on. Who knows, this is the beginning of a hell of hell and the beginning of a frenzied massacre. Ye Qisun, the father of physics of the motherland and the elite of the nation, ended up begging in ragged cotton shoes. This is tantamount to the cruelest, cheapest, and most shameless killing of culture, humanity, and civilization! Is this "clear sky"? Do we still have fantasies? Who would have thought that there would be such a bad reality in the world?)On this day 127 years ago, on July 16, 1898 (May 28, 1898), Ye Qisun, a great master of Chinese physics, was born.
