In 2009, the first batch of outstanding scientists and founding fathers who made outstanding contributions to the development of new China after the founding of New China were elected as one of the 100 people who moved China since the founding of New China.

Li Siguang founded geomechanics, which made great contribution to the development of China petroleum industry. In his early years, he made exquisite research on Odonata fossils and their stratigraphic stratification, put forward the existence of Quaternary glaciers in eastern China, established new concepts of geomechanics and tectonic system, established the concept of tectonic system, and founded geomechanics school.

It is pointed out that the three subsidence zones of the new Cathaysian tectonic system have broad prospects for oil exploration, and a way to predict earthquakes by combining active tectonic research with in-situ stress observation is created.

3. Zhang Heng

Zhang Heng (78- 139) was born in Hirako. Han nationality, a native of Xi 'e, Nanyang (now Shiqiao, Nanyang City, Henan Province), is one of the five saints in Nanyang, and is also known as the four masters of Han Fu with Sima Xiangru, Yang Xiong and Ban Gu.

China was a great astronomer, mathematician, inventor, geographer and writer in the Eastern Han Dynasty. He successively served as Langzhong, Taishiling, Shizhong and Hejian. In his later years, he became the minister of history of the DPRK due to illness. Yu Yonghe died in the fourth year (139) at the age of 62. In the Northern Song Dynasty, it was named Bo Er of Xi.

In astronomy, Zhang Heng has written Lingxian and Hunyi Illustration. In mathematics, there is a theory of calculation, and literary works are represented by Erjing Fu and Guitian. There is Zhang Hengji (14) in the capital city of Sui Shu, which has been lost for a long time. Zhang Qian, an Amin, compiled the Collection of Zhang He's Bamboo Slips, which was included in the Records of Han, Wei and Six Dynasties 130.

Zhang Heng made outstanding contributions to the development of astronomy, mechanical technology and seismology in China, and invented the armillary sphere and seismograph. He was one of the representatives of the theory of armillary sphere in the middle Eastern Han Dynasty.

Known as the "wood saint" by later generations. Because of his outstanding contribution, the United Nations Astronomical Organization named a crater on the back of the moon as "Zhangheng Crater" and the asteroid 1802 in the solar system as "Zhanghengxing". Later, in memory of Zhang Heng, Zhang Heng Museum was built in Nanyang.

Yang Zhenning,1June 1922+1 year1October was born in Hefei, Anhui Province, and is a world-famous physicist. He is currently a professor at the Chinese University of Hong Kong, a professor at Tsinghua University, an emeritus professor at the State University of New York at Stony Brook, a member of the China Academy of Sciences, a member of the National Academy of Sciences, a member of the Academia Sinica in Taiwan Province Province, a member of the Russian Academy of Sciences and a member of the Royal Society.

1957 won the nobel prize in physics; He is the first China scientist to visit China after the loosening of Sino-US relations, and actively promotes Sino-US cultural exchanges and mutual understanding between Chinese and American people. He has made great contributions to the establishment of diplomatic relations, talent exchange and scientific and technological cooperation between China and the United States.

Yang Zhenning has made landmark contributions in particle physics, statistical mechanics and condensed matter physics. In 1950s, he cooperated with R.L. Mills to put forward the theory of non-Abelian gauge field.

1956 cooperated with Li Zhengdao to put forward the law of parity non-conservation of weak interaction; A lot of pioneering work has been done in particle physics and statistical physics, and Yang-Baxter equation has been put forward, which has opened up a new direction for the study of quantum integrable systems and many-body problems.

In addition, Yang Zhenning also promoted the establishment of the Institute of Mathematical Sciences of the Chinese University of Hong Kong, the Advanced Research Center of Tsinghua University, the Theoretical Physics Laboratory of Nankai University and the Advanced Academic Research Center of Sun Yat-sen University.
