Do yourself a favor and watch a youtube clip of RF giving a speech.  Listen for at least 5 minutes.  It won't take much to absorb his rather unique style of speaking into your consciousness and this will greatly enhance this first person account of his life experiences. Besides making a significant contribution to the Manhattan Project at Los Alomos, and receiving a Nobel Prize, Feynman (pronounced fine-men) constantly developed many varied interests and pursued them passionately.  If asked to give a one word description of the guy, I guess I would use that word - passionate.  There are many interesting passages in the book, and one of the things I really admired about him was his broad view of education, particularly during his graduate studies.  While at Princeton, he met a number of students and professors in departments other than his physics major, and sat in on many of their courses just because he found the subject interesting.  And because he was a brilliant guy, he caught on quickly to basic issues and often made his unique contributions in those fields as well.  And it was interesting times - he was a student in the 30's, at Los Alamos during WWll and taught for years afterwards (and played the drums, and marched at Rio's Carnival, etc.) He mentions his wives briefly but says next to nothing about his kids.  And he had a fondness for women and met a number at clubs and bars.  Not my expectations of a physicist, but an incredibly interesting guy.  What he was not, was a great writer.  When he described problems and solutions, he raced over the details much like his mind thought.  It was impossible to get a clear grasp of what he was trying to communicate in many of these passages.  But then he always preferred speaking to audiences with a depth of knowledge in the field and was frustrated with those that couldn't keep pace.  A great guy but I wouldn't want him for a professor in one of my EE classes.  Four stars is probably a generous rating, but if you only get through a portion of this book you will be glad that you got to experience and know a little bit about Feynman.
