Yang Zhenning, male, 1922, from Hefei, Anhui. 1942 received a bachelor's degree in physics from National Southwest Associated University, 1944 received a master's degree from Tsinghua University, and 1945 received a doctorate from the University of Chicago. 1956, Yang Zhenning and Li Zhengdao put forward the theory of "parity non-conservation" in the process of weak decay (referring to the asymmetry between the real world and the mirror world), which was confirmed by experiments. 1957, Yang Zhenning and Li Zhengdao won the Nobel Prize in Physics.
Professor Yang Zhenning has a close relationship with Hong Kong and the Chinese University of Hong Kong. 1964, Yang Zhenning gave a speech at the Hong Kong City Hall at the invitation of the Chinese University of Hong Kong. Since 1970s, Yang Zhenning has frequently visited China University. 1994, he and the famous mathematician Professor Qiu Chengtong established the Institute of Mathematical Sciences. From 65438 to 0999, Professor Yang Zhenning announced that he would donate all his medals (including the Nobel Prize), papers, manuscripts and letters to the Chinese University. (Liu Guangjin)
Li Zhengdao (1926 ~) is a Chinese American physicist. /kloc-0 was born in Shanghai on October 25th, 1926 165438+ studied at the National Zhejiang University (then in Guizhou Province) and the National The National SouthWest Associated University during the Anti-Japanese War. 1946 went to the university of Chicago for further study, and 1950 received his doctorate. 1950- 195 1 teaches at the university of California, Berkeley, 195 1- 1953 works at the Princeton institute for advanced studies. 1953- 1960 worked in Columbia University (1955 as an associate professor, 1956 as a professor), 1960- 1963 as a professor of theoretical physics at Princeton Institute of Advanced Studies,/kloc-. Fellow of the American Academy of Sciences. [MRMY.NET Collection]
Li Zhengdao cooperated with Yang Zhenning in 1956 to solve the mystery of θ-τ at that time, which was later called k meson. It has two different decay modes: one decays to even parity state and the other decays to odd parity state. If parity is conserved in the weak decay process, then they must be two K mesons with different parity states. But in terms of mass and lifetime, they should be the same meson. Through analysis, they realize that parity is probably not conserved in weak interaction, and put forward several experimental methods to test whether parity is conserved in weak interaction. The next year, this theory was predicted by Wu Jianxiong's experiment. Therefore, the work of Li Zhengdao and Yang Zhenning was quickly recognized by the academic circles, and they both won the 1957 Nobel Prize in Physics. [MRMY.NET Collection]
Li Zhengdao's research field is very extensive, and he has made great achievements in quantum field theory, elementary particle theory, nuclear physics, statistical mechanics, fluid mechanics and astrophysics. 1949 cooperated with Rosenblat and Yang Zhenning to propose the universal Fermi weak interaction and the existence of intermediate bosons. 195 1 points out that there is no turbulence in two-dimensional space in hydraulics. 1952 cooperated with Piness to study the structure of polaron in solid state physics. 1954, the famous "Lie model" theory in quantum field theory was published. 1957 cooperated with Kenichi Ohmae and Yang Zhenning, and put forward the possibility of non-conservation of charge yoke and non-reversal of time. 1959 cooperated with yang Zhenning to study the molecular dynamics theory of hard-sphere bose gas, which contributed to the superfluidity research of helium ⅱ. 1962 cooperated with Yang Zhenning to study the irreversibility of electromagnetic interaction of charged vector mesons. 1964 cooperated with Nauember to study the problem that infrared divergence can be completely cancelled in the process of particle mass-free (static), also known as Lee-Nauenber theorem. The field algebra theory was put forward in the late 1960s. In the early 1970s, the problem of CP spontaneous breaking was studied, non-topological solitons were discovered and studied, and the soliton packet model theory of hadron structure was established. In the late 1970s and early 1980s, we continued to study path integration, lattice specification and time as a dynamic variable. Then the foundation of discrete mechanics was established.

Li Zhengdao is very concerned about the development of physics in China, and has visited and given lectures in China many times since 1972. Starting from 1980, he initiated and organized dozens of major universities in the United States to jointly recruit physics graduate students in China, which contributed to the training of young physicists in China. He was appointed honorary professor of Jinan University, University of Science and Technology of China, Fudan University and Tsinghua University, and member of the Academic Committee of Institute of High Energy Physics, Chinese Academy of Sciences.

I love music since I was a child, and I am a skilled violinist. 1900 graduated from the Federal Institute of Technology in Zurich, Switzerland, and obtained Swiss nationality. After that, I found a permanent job in the Swiss Patent Office in Bern. A series of his early historical achievements were achieved here. 1909, he first worked in academia and became an associate professor of theoretical physics at the University of Zurich. 19 14 at the invitation of M. Planck and W. nernst, he returned to Germany as the director of the Royal William Institute of Physics and a professor at the University of Berlin. 1933 when Hitler came to power, Einstein was persecuted for the first time because he was a Jew and resolutely defended democracy, and was forced to move to Princeton, USA. 1940 became an American citizen. 1945 retired.

Albert Einstein (1879- 1955) put forward the special theory of relativity and the general theory of relativity in 1905 and 19 15 respectively, reinterpreted the basic concepts of physics, revised Newton's mechanics, and replaced the traditional theory of universal gravitation. Einstein and Newton are giants in the history of physics. [More information about]
1905 is a magical year in Einstein's life and in the history of physics. Einstein's superhuman wisdom, generate, shines brilliantly. At the age of 26, without other academic connections, he published three papers that shocked the physics community within one year: the quantum theory of light (explaining the photoelectric effect), Brownian motion (proving the existence of molecules) and special relativity (modifying Newtonian mechanics). In the next few years, Einstein rose from an unknown young student to an internationally renowned scholar. Famous European schools compete for gifts. 19 12, Einstein was very happy to return to his alma mater in Zurich to teach, but not long after, he went to Berlin for research at the invitation of the German scientific community. While working in Germany, he divorced and later married his cousin. [More information about]
19 15, Einstein published another masterpiece-general relativity, which replaced Newton's theory of universal gravitation and had a far-reaching impact on the theoretical development of physics and the understanding of cosmic phenomena. 192 1 year, Einstein won the nobel prize in physics for explaining the photon theory of photoelectric effect and became a world-famous celebrity. At this time, the German Nazi Party rose and anti-Semitic activities spread everywhere. Einstein was extremely uneasy and hated the militaristic atmosphere prevailing at that time. 1933 Einstein was visiting the United States when Hitler came to power to persecute Jews. In order to escape Hitler's reward for assassination, he settled in Princeton University and became a professor at the Institute of Advanced Studies. Worried that the Nazi government in Germany made the atomic bomb first, it would bring disaster to the world. 1939, at the request of some famous nuclear physicists in the United States, Einstein wrote to President Roosevelt, suggesting that the scientific community should gather its strength to develop the atomic bomb. This is the origin of the famous Manhattan Project. [More information about]
Although Einstein once advocated building an atomic bomb, he was an enthusiastic pacifist and strongly advocated solving international disputes by peaceful means. 1955, Einstein died peacefully at the age of 76.

Stephen Hawking, one of the great men with international reputation in this century, is 60 years old and was born on the anniversary of Galileo's death. He is a professor in the Department of Applied Mathematics and Theoretical Physics of Cambridge University, and also the most important general relativity and cosmologist of our time. In the 1970s, he and Penrose proved the famous singularity theorem, for which they both won the Wolf Prize in Physics of 1988. He is therefore known as the most famous scientific thinker and the most outstanding theoretical physicist in the world after Einstein. "He also proved the area theorem of black holes. Hawking's life is very legendary, and he is one of the most outstanding scientists in history in scientific achievements. His position is the highest professorship in the history of Cambridge University, that is, Lucasson Professor of Mathematics once held by Newton and Dirac. He holds several honorary degrees and is a member of the Royal Society. He suffers from Luger's disease (amyotrophic lateral sclerosis) and has been in a wheelchair for 20 years. However, he was physically and mentally disabled and turned it into an advantage, overcoming his disability and becoming a supernova in the international physics community. He can't write or even read clearly, but he transcends relativity, quantum mechanics and the Big Bang theory and enters the "geometric dance" to create the universe. Although he was so helpless in a wheelchair, his thoughts traveled brilliantly in the vast space and time, and solved the mystery of the universe. [More information about www.mrmy.net]

The essence of time and space was expressed in a complete mathematical form 80 years ago, and the basic principles of quantum theory appeared 70 years ago. However, can these two most accurate and successful theories in the whole physics be unified in a single quantum gravity? Two of the most famous physicists in the world debated this question. This book is based on six speeches and final debates given by Hawking and Penrose at Cambridge University.
