During this five-year period, the journal has developed greatly. The circulation has grown rapidly. It has been welcomed by readers and has achieved encouraging results. This is inseparable from the support of readers, the author’s support and the efforts of the editorial department. I would like to extend my heartfelt congratulations to everyone! Science work is a very important part of the work of the Society. Science and technology are productive forces. However, the actual transformation of the progress of science and technology into the improvement of the production level requires a process that requires a lot of practical work. Popular science work is an important one. From
