This week's podcast is devoted to an in-depth conversation between Alok Jha and the leading theoretical physicist Nima Arkani-Hamed about the future direction of physics and some of the baffling questions it has yet to answer. Alok and Nima are joined by the science writer Graham Farmelo, author of The Strangest Man, about theoretical physicist Paul Dirac.
Graham and Nima recently took part in a day of discussions to mark the opening of the Collider exhibition at the Science Museum in London.
Going beyond the discovery of a Higgs boson at the LHC earlier this year, Nima introduces the next phase of Cern's work and explains why his certainty about the existence of the Higgs is not matched when it comes to supersymmetry.
