This volume offers a collection of papers which seek to provide further insights into the way scientific and technical knowledge is communicated (i.e., written, transmitted, and translated) nowadays, not only in the academic sphere but also in society as a whole. Language in science has traditionally been valued for prioritising objective, propositional content; however, interpersonal and pragmatic dimensions as well as translation perspectives are worth exploring in order to better understand the mechanisms of specialised communication. Accordingly, the contributions in this volume cover topics of special interest to scholars and researchers in the fields of linguistics and translation, such as the popularisation and transmission of scientific knowledge via ICTs; terminology and corpus-based studies in scientific discourse; genres and discourse in scientific and technical communication; the history and evolution of scientific language; and translation of scientific texts.
