①Chen Jingrun, who originally came from a poor family and worked as an apprentice in a grocery store, but he did not succumb to his fate. Instead, he continued to strive for self-improvement and studied mathematics by himself at night. Debach's conjecture changed his own destiny and even shocked the world.

②Helen Keller from the United States became blind in both eyes and deaf in both ears when she was one and a half years old. However, she fought against her fate unyieldingly. Under the guidance of her family teacher, she learned Braille, spelled words, and expressed herself. , also learned to speak, and at the age of 20, was admitted to the Women's College of Harvard University.

③Fireflies reflect the snow

In the Jin Dynasty, Che Yin's family was poor and had no money to buy lamp oil, but he wanted to study at night, so he grabbed a handful of fireflies to use as a lamp to study in the summer evening; Yingxue refers to Sun Kang of the Jin Dynasty who used the light reflected by the snow to read at night in winter. His spirit of reading at night inspires generations of students, inspires future generations, and sets an example forever.

④Cut a wall to steal light?

One night, Kuang Heng really wanted to read before going to bed, but because his family was so poor that he didn’t even have lamp oil, he couldn’t light a lamp to read. . When Kuang Heng was worried, he suddenly found a ray of light coming from the gap in the wall. It turned out to be the neighbor's light. Kuang Heng came up with a plan, and used a chisel to dig the small slit into a small hole. Then he held the book, leaned against the wall, and read with the weak light.

From then on, Kuang Heng borrowed the neighbor's light every night and studied hard, and finally became a famous scholar. ?

⑤Tong Dizhou, courtesy name Weisun, was born in a peasant family in Yin County, Zhejiang Province (now Yinzhou District, Ningbo City, Zhejiang Province) on May 28, 1902. Due to a poor family, he did not enter school until he was 17 years old. Graduated from the Department of Biology of Fudan University in 1927. In 1930, he received a doctorate in science from the University of Bijing in Belgium.

Extended information:

Chen Jingrun was born on May 22, 1933 in Minhou County, Fujian Province (now Lulei Village, Chengmen Town, Cangshan District, Fuzhou City).

In February 1948, he was admitted to the spring class of Fuzhou Yinghua High School, the predecessor of the Middle School Affiliated to Fujian Normal University.

In the summer of 1950, during his senior year of high school, he was admitted to the Department of Mathematics and Physics of Xiamen University ahead of schedule.

From 1949 to 1953, he studied in the Department of Mathematics of Xiamen University. After graduating from university, he was assigned by the government to teach at Beijing No. 4 Middle School.

Taught at Beijing No. 4 Middle School from 1953 to 1954. Because of his slurred speech, he was "suspended and returned to his hometown to recuperate."

In 1954, he was transferred back to Xiamen University as a data clerk. At the same time, he studied number theory and also conducted research on issues such as the close relationship between combinatorial mathematics and modern economic management, scientific experiments, cutting-edge technology, and human life.

In February 1955, on the recommendation of Mr. Wang Yanan, the president of Xiamen University at the time, he returned to his alma mater, Xiamen University, as a teaching assistant in the Department of Mathematics.

In 1956, he published "The Tower Problem", which improved Mr. Hua Luogeng's results in "The Theory of Stacked Prime Numbers".

In September 1957, due to Professor Hua Luogeng’s attention, he was transferred to the Institute of Mathematics, Chinese Academy of Sciences as a research intern.

From 1960 to 1962, he transferred to the Dalian Institute of Chemical Physics, Chinese Academy of Sciences.

Served as an assistant researcher in 1962.

In 1965, he claimed that he had proved (1 2). After being reviewed by his senior brother Wang Yuan, he published it in the Science Bulletin in June 1966.

In 1966, he published "Expressing Even Numbers as the Sum of a Prime Number and the Product of No More Than Two Prime Numbers" (referred to as "1 2"), which became a milestone in the study of Goldbach's conjecture.

In 1973, he published a detailed proof of "1 2" in "Science China" and improved the numerical results announced in 1966, which immediately caused a sensation in the international mathematics community and was recognized as a tribute to Goethe. The major contribution to the study of Bach's conjecture is the glorious culmination of the sieve method theory.

His results are called "Chen's Theorem" by the international mathematics community and have been written into many number theory books in the United States, Britain, France, the Soviet Union, and Japan. This work also enabled him to win the first prize of the China Natural Science Award together with Wang Yuan and Pan Chengdong in 1978.

In 1974, Premier Zhou Enlai, who was seriously ill, personally recommended him as a deputy to the Fourth National People's Congress and was elected as a member of the Standing Committee of the National People's Congress.

In January 1975, he was elected as a deputy to the Fourth National People's Congress, and later served as a deputy to the fifth and sixth National People's Congress. ?

In 1977, he was promoted to researcher as an exception.

In 1979, he completed the paper "The Minimum Prime Number in Arithmetic Series", which pushed the minimum prime number from the original 80 to 16, which was well received by the international mathematics community.

In 1979, he was invited by the Institute for Advanced Study in Princeton to give lectures and visits, and received widespread attention from foreign colleagues.

In 1980, he was elected as a member of the Department of Physics and Mathematics of the Chinese Academy of Sciences. (Academician)

In March 1981, he was elected as a member of the Chinese Academy of Sciences. (Academician)

He was designated as a first-level researcher in 1988.

In 1992, he served as editor-in-chief of Journal of Mathematics and won the first Hua Luogeng Mathematics Award. ?

At 1:10 pm on March 19, 1996, Chen Jingrun died in Beijing Hospital at the age of 63. His final contribution to science was to donate his body for hospital dissection. ?

Main achievements:

His research in the field of mathematics has been fruitful. The paper he wrote, "Theory of Functions of Multivariable Complex Variables in Typical Fields," won the first prize of the National Invention Award in January 1957, and he published monographs in Chinese, Russian, and English editions; in 1957, he published "Introduction to Number Theory"; in 1959 Leipzig first published "Estimation of Sums of Exponents and Their Application in Number Theory" in German, and successively published the Russian and Chinese versions.

In 1963, the book "Typical Groups" co-written by him and his student Wan Zhexian was published. He initiated the establishment of the Institute of Computer Technology and was one of the earliest scientists in China to advocate the development of electronic computers.

In 1957, Chen Jingrun was transferred to the Institute of Chinese Academy of Sciences. As a new starting point, he studied harder. After more than 10 years of calculation, in May 1965, he published his paper "Expressing even numbers to represent the sum of a prime number and the product of no more than 2 prime numbers." The publication of the paper was highly valued and praised by the world's mathematical community and famous mathematicians.

The British mathematician Halberstam and the German mathematician Richter wrote Chen Jingrun's paper into a mathematics book and called it "Chen's theorem".
