Many people know that sum won the Nobel Prize by virtue of the law of parity non-conservation, but few people know that he did not win another important achievement of the Nobel Prize: Yang-Mills theory. It occupies an important position in modern physics, and has profoundly influenced the development of physics since the middle of the 20th century.
Young-Mills theory points out the direction for the grand unification theory. Based on this theory, physicists unified electromagnetic force and weak nuclear force, and founded the theory of weak electric unity. In the early universe with extremely high temperature, electromagnetic force and weak nuclear force are unified electric weak forces. On this basis, the standard model of particle physics unifies the strong nuclear force. That is to say, under the framework of Young-Mills theory, the three basic forces except gravity have been unified. In the last thirty years of Einstein's life, he was obsessed with this theory, but he never finished it. Yang Zhenning has finished 75%. How great do you think he is?
In addition, they have made outstanding contributions to statistical mechanics and condensed matter physics, and some even won the Nobel Prize, such as the Young-Baxter equation, which is the third major physical achievement. It is precisely because Yang Zhenning has made many pioneering contributions to physics that he is recognized as a master of physics, ranking first today, enough to rank among the top 20 greatest physicists in history. He is also the first Chinese-American scientist to visit China after the loosening of Sino-US relations (he has now returned to China), actively promoting Sino-US cultural exchanges and mutual understanding between Chinese and American people, and making great contributions to the establishment of diplomatic relations, talent exchange and scientific and technological cooperation between China and the United States.
Mr Yuan Longping Sr, the pioneer and leader in the field of hybrid rice research, is known as the "father of hybrid rice". He devoted himself to the research, application and popularization of hybrid rice technology, invented the "three-line method" indica hybrid rice, successfully developed the "two-line method" hybrid rice, and established the technical system of super hybrid rice, making the research of hybrid rice in China always at the world leading level. By the end of 20 17, hybrid rice had been popularized in China for more than 9 billion mu, and rice production increased by more than 600 billion kg. He went to India, Vietnam and other countries many times to teach hybrid rice technology to help overcome food shortage and hunger. It has made outstanding contributions to ensuring China's food security and world food supply. The outstanding achievements of the elderly not only belong to China, but also affect the world.
Here, I would like to pay tribute to two China technology giants!
