Does size really matter when it comes to our brains? Does a bigger brain mean a smarter person? And how much do we really know about our brains? Michio Kaku, one of the world's most popular science communicators, will join Richard and Peter to help try to answer the big "What IF". He will also blow our minds with his insights on "The Future of the Mind", the title of his seminal 2014 best seller. Rita Carter, author of "The Human Brain Book" and "Mapping of the Mind", will also join us to discuss the correlation between size and "smarts" when it comes to the brain and to help us better understand the 3 pound slimy, song mass that is the human brain.
