China Post recently issued "Modern Chinese Scientists (8)" commemorative stamps, Wang Daheng , Huang Kun, Yu Min, Chen Jingrun four scientific masters boarded the "national card". This set of commemorative stamps is a set of 4, with a face value of 4.80 yuan, and the planned number is 6.95 million sets.
Wang Daheng, an applied optician, one of the founders of my country's optical industry. It has made outstanding contributions to the development of various large-scale optical observation equipment, and has played an important role in the development of my country's optical industry and metrology science.
Huang Kun , solid-state physics, semiconductor physicist. Mainly engaged in solid-state physics, semiconductor physics, etc., he is one of the pioneers of semiconductor physics research in China.
Yu Min , nuclear physicist. Solved a series of basic problems in the breakthrough of the principle of my country's hydrogen bomb, led the theoretical research and design of nuclear weapons for a long time, and made important contributions to the further development of my country's nuclear weapons to the international advanced level.
Chen Jingrun, a mathematician. Mainly engaged in the research of analytical number theory, and achieved internationally leading results in the research of Goldbach's conjecture. In May 1966, the proposition "1+2" was proved, and this result was praised internationally as " Chen's theorem ".
This set of stamps uses realistic expression techniques to vividly and meticulously portray the classic images of four modern scientists. The background of the screen shows the scientific research direction and results of the four scientists.
The first picture is: the 150 large-scale film theodolite developed by Wang Daheng and Changchun Optical Machinery;
The second picture is: Huang Kun's original solid-state physics textbook cover conceptual drawing and "Yellow Equation";
third picture: Yu Min and my country The successful picture of the first hydrogen bomb test;
The fourth picture is: Chen Jingrun's important research results in the process of proving the "Goldbach Conjecture".
