There are Known Knowns, Known Unknowns, and Unknown Unknowns. And then there is Dr Karl. The inimitable Dr Karl reigns once more in his Dynasty of 34 Science Books with scintillating science scenarios, techie tales and tasty morsels to sate even the most haemoglobin-thirsty of his army of followers. In Game of Knowns, he 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. Thereby Science is decreed to be the only true ruler of the kingdom, and there is none better to claim the Throne than Australia's most trusted and knowledge-thirsty scientist - Dr Karl.
