He wrote the research results of Goldbach's conjecture into the paper "Even number represents the sum of the products of a prime number and a prime number not exceeding two". Once published, "Big even number represents the sum of the products of a prime number and a prime number not exceeding two" immediately attracted the attention of international mathematicians.
British mathematician Haberstein and German mathematician Li Xite spoke highly of Chen Jingrun's Goldbach conjecture, and wrote the research results of Chen Jingrun's Goldbach conjecture into a book named Chen Theorem.
(2) Tu Youyou has been engaged in the research of integrated traditional Chinese and western medicine for many years, creating new antimalarial drugs artemisinin and dihydroartemisinin. A colorless crystal with the molecular formula of C 15H22O5 was successfully extracted from 1972 and named artemisinin.
20 1 1 In September, artemisinin, a drug used to treat malaria, saved millions of lives around the world, especially in developing countries, and won the Lasker Prize and the "Outstanding Achievement Award in Life Science" of GlaxoSmithKline China R&D Center.
20 15- 10 Tu Youyou won the nobel prize in physiology or medicine for discovering artemisinin, which can effectively reduce the mortality of malaria patients. She became the first China person to win the Nobel Prize in Science.
(3) Stephen Hawking was born in Oxford, England on 1942 10. He was terminally ill when he was young. However, he persevered, overcame his pain and became a world-renowned scientist. Hawking went to Cambridge University for postgraduate study after graduating from Oxford University. At this time, he was diagnosed as "Luger's disease" and soon became completely paralyzed.
He became a world-recognized giant of gravitational physics in the incredible difficulties of ordinary people. Hawking is a Luxun professor of mathematics at Cambridge University. His black hole evaporation theory and quantum cosmology not only shocked natural science, but also had a far-reaching impact on philosophy and religion.
(4) Ma Yun, Alibaba, a small online workshop with 18 people and 500,000 yuan, became the world's largest B2B business website eight years later; Eight years later, the small sampan drifting in the West Lake became the Internet carrier of China in the Pacific Ocean. Eight years later, this ordinary English teacher became the head of a world-class Internet company.
(5) Deng Yaping, she was born in a table tennis family, and her father Deng Dasong was a table tennis player in Henan Province. Since Deng Yaping was more than two years old, his father often put Deng Yaping on a bicycle and took Deng Yaping to the workers' club to watch them play. Deng Yaping learned to play table tennis with his father at the age of 5, and his father developed a set of training methods different from routines.
At first, Deng Yaping shot horizontally. Because Deng Yaping was slow and had short arms, she was asked to take publicity photos the next year. Deng Yaping was particularly serious since she was a child. Deng Yaping encountered many difficulties in her growth.
Because she is short, the provincial team doesn't want her. My father told Deng Yaping all this. Deng Yaping understood his father's meaning: if others say you can't do it, you should fight for breath and practice more. Therefore, Deng Yaping was excellent since she was a child, and her training was particularly hard.
Extended data:
Goldbach conjecture is one of the three major mathematical problems in the modern world. Goldbach put forward the following conjecture in his letter 1742 to Euler: any even number greater than 2 can be written as the sum of two prime numbers.
But Goldbach himself could not prove it, so he wrote to the famous mathematician Euler to help him prove it, but until his death, Euler could not prove it. Because the convention that "1 is also a prime number" is no longer used in mathematics, the modern statement of the original conjecture is that any integer greater than 5 can be written as the sum of three prime numbers.
Any sufficiently large even number can be expressed as the sum of a number with no more than one prime factor and a number with no more than b prime factors, and the proposition is called "a+b". 1966 Chen Jingrun proved that "1+2" holds, that is, "any sufficiently large even number can be expressed as the sum of two prime numbers, or the sum of a prime number and a semi-prime number".
Tu Youyou, female, pharmacist. 1930 was born in Ningbo, Zhejiang province on February 30th, and was admitted to Peking University in195/0, studying in the department of biochemistry and pharmacy of medical college. 1955, graduated from Beijing Medical College (now peking university health science center).
After graduation, he received Chinese medicine training for two and a half years and has been working in China Academy of Traditional Chinese Medicine (renamed China Academy of Traditional Chinese Medicine in 2005). During this period, he was promoted to master tutor and doctoral tutor, and now he is the chief scientist of Chinese Academy of Traditional Chinese Medicine. Lifelong researcher and chief researcher of Chinese Academy of Traditional Chinese Medicine, director of artemisinin research and development center, doctoral supervisor, pharmacist, winner of Nobel Prize in Medicine.
