As I am a bit of a nerd I like ‘The infinite monkey cage’.
Hosted by physics Professor Brian Cox and comedian Robin Ince.
This is a panel based discussion where both experts and celebrity laypersons attack a broad range of Science topics with much humor and levity from all angles. The wide variety of topics from evolution to the universe, and the comical treatment, creates a very entertaining break from work.
I also like documentaries and keeping up to date with contemporary topics.
For this I rely heavily on BBC and Netflix who have some great documentary topics. This podcast library is from the BBC World Service and covers a wide range of current world issues
