Presentation and discussion held at the Wikimedia Germany event "Principles and barriers of knowledge equity in science" as part of the Open Science Fellows Program https://en.wikiversity.org/wiki/Wikimedia_Deutschland/Open_Science_Fellows_ProgramThis input highlights different facets of linguistic diversity in science: English as a lingua franca and applied languages in different disciplines, linguistic diversity in everyday scientific life as well as via translation software and technical options to publish multilingually. With a subsequent reflection: what are the possibilities for inclusion arising from applied language diversity in everyday scientific life?
