Chen Jingrun, a celebrity material struggling for his ideal, taught himself English, German and even Russian in order to confirm Goldbach's conjecture. Whether it is hot or cold, Chen Jingrun will spend more than ten hours studying Goldbach's conjecture. When Chen Jingrun confirmed Goldbach's conjecture, the draft paper of optical calculus was packed in several sacks.
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.
Deng Yaping was born in a table tennis family, and his father Deng Dasong was a player of Henan table tennis team. 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.
