I have always liked reading about Dr.Feynman! Infact it all started with Surely..Mr.Feynman. This book goes out to show that any guy, can split his time between love and work(which is most often missing from these high profile Scientists/Physicist).His desire to know the root cause of Challenger mishap, and how he goes on to demonstate what transpired the failure of Challenger mishap is very inspiring.All in All a good buy if you are an ardent fan of him!
