The theme of my speech today is to popularize science to the community and create a harmonious society. Why do you want popular science to enter the community? In today's society, with a large number of retirees and laid-off workers entering the community, the emergence of multi-level and diversified material and cultural needs in the community has reached a historical peak. How to solve these contradictions? I thought about the power of science. Science and technology are the primary productive forces, and scientific thinking is an important spiritual force. If a nation wants to stand on its own feet and the country wants to be rich and strong, it must purify its thoughts with scientific spirit, thus greatly improving the scientific and cultural literacy of the whole nation. There is no doubt that advocating science is our due quality; It is the concept of honor and disgrace and the general program of action that every citizen should firmly establish, and it is also the best way to change the community management mode and working mode, let popular science enter the community, and let the power of science meet the growing material and cultural needs of the people. Therefore, it is imperative for popular science to enter the community. Wang Zhenwei and Huo Dou are volunteers in the community. They like to be with their children on weekdays. During the winter vacation, they just want to do something for the children. Early in the morning, they came to the community service center early. Liu Lihua is a teacher, so she wants to use the community library to tell stories to children and help them with their homework. In the community library, Mr. Liu told many inspiring stories to the children, such as Meng Mu's three tricks and Wang Xizhi's calligraphy practice, and educated the children to study hard, honor their parents, respect the old and love the young; Wang Zhenwei, who likes playing chess on weekdays, went into the chess room as soon as he arrived at the community, where he taught the children to play chess. Children who haven't learned it start from the most basic, and children with higher chess skills compete with him. There is an active confrontation atmosphere in the chess room; Huo is a painting lover, so he wants to turn his hobby into knowledge and teach it to children. He brought his own brush and distributed it to the children. He taught the most basic painting knowledge, took pains to explain it, and reminded the problems that should be paid attention to. On weekdays, noisy children are no longer noisy, but quietly listening, drawing and studying seriously. This day is a full and busy day for children and a very happy day.
