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.

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.

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.
