In Game of Knowns, Dr Karl divulges why psychopaths make good kings, how smartphones dumb down our conversations, why the left side of your face is the most attractive, how the female worker bee gets a raw deal and why we drink beer faster when it is served in a curved glass. He discloses the amazing opportunities that 3D Printing will bring, the magic of hoverboards, solemnly shares why dark matter matters, and spills the scientific basis of wealth distribution.
