This popular American radio programme about science and philosophy is aimed at an audience of general listeners and is characterised by its innovative sound design. Each podcast takes a broad theme, such as Parasites, Placebo or Games and takes an exploratory, associative approach to the subject, aiming to stimulate curiosity rather than reach a definitive conclusion about the chosen topic. Each show is divided into several parts, featuring interviews with experts and occasional ventures into audience participation and ‘thought experiments’. The programme’s host Jad Abumrad is a trained musician and his background as a composer is evident in the podcast’s approach to sound, where music, speech and effects overlap, forming an integral part of the programme’s experimental, freewheeling ethos.
