The Wondrous Kingdom of Number is a representative work among Li Yupei’s scientific fairy tales themed around mathematics. Highlighting the theme of numbers，the work systematically popularizes mathematical knowledge，including integers，fractions，decimals，and algebra. It simultaneously promotes scientific thought centered around dialectical development and fully constructs a mathematical fairy-tale universe as a “secondary world.” Emphasizing interactive narrative techniques between the fairy-tale and real worlds，the book employs personification and concretization to enhance the vividness of the “Kingdom of Number，” creating an immersive and tangible fairy-tale experience. In terms of creative techniques，it adheres to the principle of child-centeredness by stressing a simple plot structure，narrative conflicts，and engaging storytelling. By using accessible scientific fairy tales to dissolve the rigidity of knowledge，the dissemination effect of mathematical concepts and scientific thought is optimized.

Li Yupei’s mathematical fairy tales combine literary and artistic qualities with unique educational value. This study analyzes his representative work，The Detective Takes the Case，from the perspective of mathematical core competencies. By further examining a broader range of his fairy tales，the paper explores his creative methods and discusses their potential for transmedia development. The goal is to provide insights and references for contemporary mathematical science popularization.

With the rapid development of micro-dramas in recent years，their use for science popularization has been explored across multiple disciplines. However，there remain concerns about the sustainability of micro-drama content due to its rapid production and short lifespan. This article discusses the practical foundation and growth potential of science-popularization micro-dramas and proposes innovative insights for their content production from four perspectives: experimenting with novel narrative techniques，enhancing interactive experiences，integrating cross-disciplinary resources，and employing AI technologies to empower innovation in micro-drama production. Ensuring scientific accuracy and content sustainability will be a crucial focus for future research in digital science popularization.

Popularizing cutting-edge scientific and technological resources is an essential theme in current science communication efforts. Taking “Tiangong Classroom”，China’s first space science education brand，as a case study，this article analyzes and discusses innovative practices in youth aerospace science popularization from various perspectives，including scenario innovation，content innovation，format innovation，and functional innovation. The article further suggests expanding content creation，reinforcing the scientific spirit，innovating popular science expressions，and exploring distinctive communication channels.

Mathematical popularization serves as a vital means of disseminating mathematical knowledge and cultural insights，helping the public grasp mathematical fundamentals while inspiring a passion for the subject. This，in turn，promotes broader applications and advances in mathematics across various fields. As an outstanding representative in mathematics popularization，Wang Juncen’s works continue to be regarded as classics. In 2022，his renowned series was republished as Fun Mathematics for Children. Employing familiar examples，the series creates an engaging atmosphere，conveying mathematical concepts through concise，dialectically unified storytelling. Mathematical popular science writers can derive numerous insights from Wang’s works，including his extensive and vivid content selection，lively modes of expression，dialectical cohesion of knowledge，and skillful narrative integration.

As China’s first documentary-style variety show focused on agriculture，Become a Farmer explores an innovative practical approach to rural revitalization and science popularization within domestic variety programs. The show effectively incorporates agricultural science knowledge through multiple dimensions，including exploring science popularization themes，constructing engaging scenarios，reconstructing narratives，and enhancing communicative effects. It successfully achieves immersive and panoramic dissemination of professional agricultural knowledge to the public. The experiences from this program offer valuable insights for innovation in science popularization narratives among domestic variety shows.

With the rapid advancement of artificial intelligence and brain-computer interface technologies，the evolving relationship between humans and technology，as well as the crisis of human subjectivity，has become unavoidable topics in contemporary humanities research. Among classic science fiction films，Kon Satoshi’s Paprika presents a representative vision of posthuman subjectivity. Through imaginative interactions between humans and brain-computer interfaces，spectacular representations of the metaverse，and the embodied construction of subjectivity，the film articulates a fluid，decentralized form of posthuman thought grounded in humanistic concern. Exploring and re-evaluating Paprika helps us reaffirm humanity’s unique subjective value as we approach the imminent era of general artificial intelligence and the posthuman future.
