This book is a 'research' book that looks into different situations (obviously unusual and extra-ordinary situations) and shows why those situations are extraordinary. It talks about Bill Gates and how he became successful, why famous hockey players are mostly born between Jan- Mar., what lead to Korean Airline crashes and how they turned it around. It was such a cool book. I highly recommend it. It's really not a research book, but he does present information or data, but please don't be deterred. It's not like a textbook at all, it's really good.
