Science of the Discworld - Professor Jack Cohen

The Science of Discworld is a trilogy of popular science books written by Terry Pratchett in collaboration with mathematician Ian Stewart (not Iain Stewart) and biologist Jack Cohen.  Each book combines a Discworld-based story by Pratchett interwoven with chapters on real world science by Stewart and Cohen.  In this highly entertaining presentation, Professor Cohen showed us how to view the science underpinning our world (‘Roundworld’) from a completely different perspective.
