Acquisition of knowledge and its limits are debated by Rupert Sheldrake, Suchitra Sebastian, and Tommy Curry. They challenge the Western view of knowledge, discuss alternative ways of knowing, and emphasize the importance of questioning and embracing discomfort in science.

The podcast features Suchitra Sebastian, Philip Goff, and Hilary Lawson discussing the mysteries of emergence. They explore the concept's role in understanding consciousness, free will, and life. Critics debate if emergence truly explains phenomena or if it's a misleading illusion. The discussion delves into quantum physics, superconductivity, differentiation, consciousness, and panpsychism, challenging traditional views and proposing new perspectives on reality.

Melvyn Bragg and guests discuss the discovery made in 1911 by the Dutch physicist Heike Kamerlingh Onnes (1853-1926). He came to call it Superconductivity and it is a set of physical properties that nobody predicted and that none, since, have fully explained. When he lowered the temperature of mercury close to absolute zero and ran an electrical current through it, Kamerlingh Onnes found not that it had low resistance but that it had no resistance. Later, in addition, it was noticed that a superconductor expels its magnetic field. In the century or more that has followed, superconductors have already been used to make MRI scanners and to speed particles through the Large Hadron Collider and they may perhaps bring nuclear fusion a little closer (a step that could be world changing).The image above is from a photograph taken by Stephen Blundell of a piece of superconductor levitating above a magnet.With Nigel Hussey Professor of Experimental Condensed Matter Physics at the University of Bristol and Radbout UniversitySuchitra Sebastian Professor of Physics at the Cavendish Laboratory at the University of CambridgeAndStephen Blundell Professor of Physics at the University of Oxford and Fellow of Mansfield CollegeProducer: Simon Tillotson
