Which scientist do you think has developed the most in modern China for China?

Different insights and different results.

The scientific research carried out by scientists is specialized in different fields. All scientists who have made achievements, inventions, and monographs have contributed to the country and mankind. The criterion for judging a large contribution is that it has a direct and obvious effect on overcoming the scientific bottlenecks and problems of a country or the world, has made significant achievements in promoting the development of the current social productive forces and economic development, and has made major breakthroughs in improving national defense and military technology.

The successful cultivation of the first generation of indica hybrid rice in China has solved the problem of eating for Chinese to a large extent. As the staple food of more than half of the world's population, the emergence and promotion of hybrid rice has also brought good news to ensure world food security. It provides a stable external environment for national development.

Qian Xuesen was the organizer and chief designer of the development of the "two bombs" and the true father of the atomic bomb. This talented young man who studied under Marie Curie gave up the impact of the Nobel Prize and returned to China to participate in the construction, he participated in the early establishment of the Chinese Academy of Sciences, and led the establishment of China's first nuclear physics research institution. He has always been concerned about the development of China's nuclear industry, emphasizing that it should not only serve the military but also serve the civilian population.

In 1992, he died of illness at the age of 79. On the eve of the 50th anniversary of the National Day, the Military Commission of the Communist Party of China posthumously awarded Qian Sanqiang the "Two Bombs and One Star Meritorious Service Medal" made of 515 grams of pure gold, commending the great contribution of this scientific hero.

Li Siguang is the founder of China's geomechanics, one of the main leaders and founders of China's modern earth science and geology, and most importantly, he has made important contributions to the development of China's atomic bomb uranium mine and petroleum industry. Li Siguang foresaw long ago that new China needed uranium ore resources for national defense and economic construction. When he returned to China in 1949, he brought back a gamma meter from England, which played an important role in China's later search for uranium.

Under his auspices, China has discovered a series of uranium deposits, and the production of uranium has been able to meet the needs of China's nuclear industry.

Today, we have a comfortable and stable life because we have a strong national strength, and an important foundation of this is strong military strength, which is naturally indispensable for economic development in the future, but military strength is the basis for sustainable and stable development.

Yuan Longping. Yuan Longping's research on hybrid rice has helped China solve its food problem, and it can be said that it has made the greatest contribution to China's development.

Qian Xuesen, he is known as the "father of China's missiles" and "the father of China's aerospace". His return to China has promoted the development of China's space missile industry for at least 20 years.

I think it was the scientist who invented the two bombs and one satellite, after all, the two bombs and one satellite established our country's status as a great power after World War II, and one example of this is the permanent seat of the United Nations.

1. Wu Liande: The first person in modern medicine in China

Wu Liande, a public health scientist, is a pioneer in China's quarantine and epidemic prevention cause. At the end of 1910, when the pneumonic plague epidemic in Northeast China was precedent, he was appointed as the chief medical officer and went deep into the epidemic area to lead the prevention and control. In 1911, he presided over the International Conference on Plague Research.

Under his vigorous advocacy and promotion, China took back its sovereignty over the quarantine of its seaports. He successively presided over the establishment of 20 quarantine institutes, hospitals and research institutes, and also founded Harbin Medical College (the predecessor of Harbin Medical University). Together with Yan Fuqing and others, he initiated the establishment of the Chinese Medical Association and founded the Chinese Medical Journal.

2. Liu Ruiheng: The founder of China's modern public health

Liu Ruiheng (1890-1961): The word Yueru is a native of Nangong. He was admitted to Peiyang University in 1903, and in 1906 he was sent to the United States to study at Harvard University without graduating.

He is a well-known medical expert in China, the founder of trauma medicine in China, the founder of modern public health in China, and one of the first batch of international students at Harvard University.

3. Gao Shiqi: the pioneer and founder of the chemical science popularization cause of modern and modern chemistry, bacteriology and virology in China.

Gao Shiqi (November 1905 - December 19, 1988, formerly known as Gao Shichi, a native of Aofengfang, Min County, Fujian Province (now Fuzhou City), changed his name to Gao Shiqi, abandoned his career and money, determined not to be an official, not to love money, and to benefit China as a scientist. He received a bachelor's degree in chemistry from the University of Chicago in 1927. He graduated from the University of Chicago Medical Graduate School in 1930.

In honor of his contributions, China named an international planet Coats. Scientist, chemist. Pioneer and founder of Chinese chemical science popularization by bacteria and virologists.

4. Wang Shizhen: The founder and founder of modern nuclear medicine in China.

Wang Shizhen (March 7, 1916 – May 27, 2016): a native of Fuzhou, Fujian, a biochemist, a nuclear medicine scientist, and the founder of China's nuclear medicine industry. M.S. and Ph.D. from the University of Iowa.

He has served as an associate researcher at the Institute of Radioactivity at the University of Iowa, a professor at Peking Union Medical College, the director of the Capital Center for Nuclear Medicine at the Chinese Academy of Medical Sciences, the deputy director and honorary director of the Institute of Radiation Medicine, and the director of the Academic Committee of the State Key Laboratory of Nuclear Medicine. Since the 1940s, Wang Shizhen has done a lot of systematic research on thyroxine.

5. Wu Mengchao: The father of hepatobiliary surgery in China, the first liver model in China

Wu Mengchao, male, born on August 31, 1922, was born in Minqing County, Fujian Province, returned overseas Chinese from Malaysia, graduated from Tongji University in 1949 with a bachelor's degree; Hepatobiliary surgeon, academician of the Chinese Academy of Sciences, under the tutelage of Qiu Fazu (honorary dean of Tongji Medical College, Huazhong University of Science and Technology), winner of the 2005 National Science and Technology Award.

1. Wang Ganchang (born in Changshu, Jiangsu, nuclear physicist, founder of China's inertial confinement nuclear fusion research. It is one of the main scientific and technological leaders in China's nuclear development.

2. Zhao Jiuzhang (born in Kaifeng, Henan, geophysicist and meteorologist. He is a pioneer of geophysics and space physics in China, and one of the advocates, organizers, and founders of the artificial satellite industry.

3. Guo Yonghuai (aerodynamicist, born in Rongcheng County, Shandong Province. He is one of the founders of mechanics in Chinese mainland, and has made outstanding contributions to mechanics, applied mathematics and aeronautical defense. Chanting omens.

1. Zhan Tianyou and the Beijing-Zhangjiakou Railway: The Beijing-Zhangjiakou Railway is the first railway trunk line designed and constructed by the Chinese themselves, and it was built when modern China's science and technology were very backward and foreigners sarcastically mocked that Chinese railway engineers had not yet been born.

2. Feng Ru developed an airplane: Feng Ru was China's first aircraft designer, manufacturer and aviator, and the flight altitude, speed and range of the aircraft developed by Feng Ru set a world record at that time.

3. Gong Zhenlin, a weapons manufacturer: After the outbreak of Gong Zhenlin's Opium War, he saw that the great mountains and rivers were trampled by the British invaders, so he worked hard to study science and technology, improve weapons, and consciously devoted himself to the anti-aggression war. He personally went to the battlefield in Yongdong to carefully observe the British steamers, and made "wheel ships" and "wheel warships" driven by manpower.

During Lin Zexu's "meritorious service" in Zhejiang, he was transferred to work in the artillery bureau and built a "cardinal's new gun mount", which enabled the cannon to rotate in all directions and shoot flexibly.

4. Li Shanlan and "Fang Yuan Explains the Quiet": Fang Yuan Explains the Quiet is a mathematical work of the Qing Dynasty. It is about the study of power series formulas.

Li Shanlan created a kind of "sharp pyramid technique" and used it for the power series of logarithmic functions; Solve a variety of math problems by finding the sum of the spikes. Although he had not yet been exposed to calculus when he created the "sharp cone", he had actually come up with formulas for definite integrals. The Englishman Wei Liali believes that in the book written by Li Shanlan, "the reason is very close to the differential".

Li Shanlan's achievement shows that even if there is no calculus introduced from the West, Chinese mathematics will use its own special way to achieve calculus in a unique way of thinking, and basically complete the transformation from elementary mathematics to advanced mathematics.
