Química na poesia e poesia na química

Goethe's novel 'Elective Affinities', published in 1809, uses Bergmann's concept of 'Elective Attractions', from 1775, as a metaphor for social relations. Its analysis demonstrates the possibility of describing chemical theories, characterised by an anthropomorphic language, using poetic means. Due to the inherently poetic nature of chemical language, Nobel Laureate Roald Hoffmann (2002) suggests relaxing strictures against expressing emotions and personal motives in scientific publications, thus enabling the use ofing poetry to understand and communicate science. Based on the analysis of Goethe's novel and Hoffmann's essay, this article discusses the possibility of using poetic means to help understand chemistry and communicate its research results.
