A popularização da ciência no TikTok Fatos curiosos com Antonio: uma análise multimodal à luz da semiótica social.

During the Covid-19 pandemic, many researchers and scientists took advantage of technologies made available on the web to combat misinformation, including winning over a significant portion of the young public. From this perspective, this article analyzes the most liked and commented video on the profile of tiktoker Antonio Miranda, published during the pandemic. The objective is to analyze and discuss how the semiotic resources configured in the video contribute to the construction of meaning and the practice of popularizing science in the digital environment, through TikTok. The theoretical foundation of this study is Multimodal Social Semiotics (Burn, 2013; Hodge; Kress, 1988; Kress, 2010; van Leeuwen, 1999), which focuses on communicative social practices of creating meanings of all types, be they verbal, visual and/or sound. The most recurrent semiotic resources in filming and editing point to a powerful interaction between Antonio and the viewer, characterized by involvement, proximity, relaxation, devoid of power hierarchies, as if their worlds were familiar, similar and coinciding. Furthermore, gestures, voice and verbal language play the role of transmitting credibility, emphasizing key words and providing opportunities for fluidity and assertiveness in understanding the explanation. In this way, Antonio's video uses semiotic choices that distance him from the "ivory tower", where scientists are supposed to be located, to get closer to the street, people and their daily lives.
