3.2 Day 1 Timetable
Scientists throughout the world are increasingly interested in the relationship between science and society. Part of their concern is with the social responsibilities scientists have in relation to broader public interests. That raises important issues to do with the ethical and social dimension of scientists' work and how scientists explain â€“ and perhaps justify â€“ their work to the wider public.
