I get the impression that some users of this forum are interested in science. Could I recommend this fantastic and informative podcast produced by the BBC chaired by Melvin Bragg, a writer and presenter.
The concept is Bragg invites a panel of experts on a particular subject and they spend an hour or so discussing the subject to a fair degree. All the episodes come with a comprehensive reading list. The most recent one is on Paul Dirac.
