Launched in March 2019 (and named “Living Proof” in February 2021), the INI podcast series aims to highlight the diverse people and explore the many interconnected topics linked to the Institute’s activities. Interviewees range from visiting academics and lecturers to mathematicians, other scientists, musicians, artists, students, and prominent figures within the University of Cambridge and beyond. The podcast typically involves mathematical themes, but is specifically aimed at a general audience. The focus is on the subjects being interviewed and the social stories they have to tell, not just on the significance and details of the research they may be undertaking. We hope there is interest and inspiration here for everyone.
