In this episode, Rachael and Richard talk with Dr Sarah Qidwai, a postdoctoral researcher at the University of Regensburg, Germany. Sarah’s work explores transnational and local perspectives on scientific disciplines during the long nineteenth century. In this episode, we discuss the focus of Sarah’s doctoral thesis, the Muslim polymath Sir Sayyed Ahmad Khan (1817-1898), and her latest project entitled ‘Scientism and Empire’ while examining how disciplines such as astronomy, geology, and evolutionary biology operated within the confines of Empire in the 19th Century.
