This audio book has been a car journey hit for my family; adults and older kids are fascinated, while even the 6 year-old has picked up a few things. Reviews of the printed book will tell you lots about the material, so I will concentrate on the audio format. The reader is not Prof. Feynman, and his voice is very calm and easy-going. My teenagers felt that the reader's voice put them off because fairly exciting stories were told in this easy-going voice with not too much variation of tone, and initially there was a bit of eye-rolling but they soon started enjoying it and asked me to buy the book. On the other hand, as a driver I found it relaxing to listen to. The reader has a conversational tone of voice so it could be as if Prof. F really was telling his own stories, but I think he would have been more animated. Anyway, the anecdotes meander from physics to strip bars, art to drumming, what scientists should aim for, and how governments always get things wrong. Listening to this has sparked lots of interesting conversations, and I have been looking forward to ferrying the kids around! The second part, "What do you care what other people think?", is different - a collection of letters and more personal anecdotes, including the very sad story of the first Mrs Feynman's early death. I feel inspired now to seek out other interesting biographies.
