This accessible book introduces students to perspectives from the field of science and technology studies. Putting forward the thesis that science and democracy share important characteristics, it shows how authority cannot be taken for granted and must continuously be reproduced and confirmed by others. At a time when fundamental scientific and democratic values are being threatened by sceptics and populist arguments, an understanding of the relationship between them is much needed. This is an invaluable resource for all who are interested in the role of scientific knowledge in governance, societal developments and the implications for democracy, concerned publics and citizen engagement.
