Dr Roberto Trotta is Reader in Astrophysics at Imperial College London and also directs Imperial’s Centre for Languages, Culture and Communication. His recent book The Edge of the Sky sets out to explain cosmology using only the most common thousand words in English - which do not include ‘universe’, ‘scientist’ or ‘telescope’. He is also exploring how we might use different senses to think about cosmology and describes his collaboration with leading chefs at Kitchen Theory around gastronomy for communicating complex ideas. In this podcast we discuss our ideas about communication and translation in science, medicine and the arts.
