This newspaperA few days ago, China Post issued a special stamp entitled "The Beauty of Mathematics". The Provincial Association for Science and Technology, the Provincial Mathematical Society and Shanxi Post jointly held the first stamp launch event in Taiyuan No. 5 Middle School to promote philatelic culture, inspire young people to discover the charm of mathematics and cultivate philatelic hobbies.

This set of stamps has a total of 4 tables, which are "Pi", "Pythagorean Theorem", "Euler's Formula" and "Möbius Strip". For the first time, daylight fluorescent ink was used for printing, echoing the multi-dimensionality of mathematics through the multi-dimensional perspective of the picture; The ultra-fine line printing breaks the record of stamp printing fineness, reflecting the mathematical rigor; The "key" style is shaped with shaped perforations, inspired by "mathematics is the key to open the door to science", which means to unlock the mystery of science with the key of mathematics.
