As every book about Feynman, wonderful! Finished on December 4th, 2018.

A pleasant collection of letters by a human who loved puzzles, a flare for attracting others to his passions, and speaking in a tone that was understandable to those not deeply studied in quantum and high energy particle physics.

A brilliant perspective of one of the most popular person in the field of science. He had an appetite for life, an insatiable appetite for knowing things.All these is well shown through all the letters inside. You will know him better as you read all of them.

I listened to this on cd. Professor Feynman had a fantastic sense of himself and his strengths, and weaknesses, and it is interesting to hear how he lived his life through his own words. The letters that he wrote, and were wrote to him, are well narrated and given a real life to them. It shows a man who knew exactly who he was and what honor, truth, and scientific research means without becoming egocentric or self-involved. Truly a fantastic audiobook and person.

Lovely.

This was a really great view into the life of Richard Feynman. The book is broken up into time-frames from early life until death and you see letters to and from him to family members and associates. We hear about his marriages, the atomic bomb, his Nobel Prize, and the Challenger disaster. If you like Richard Feynman, you'll definitely enjoy this book.

A very insightful approach to learning more about a very interesting person.

The first book by a Nobel Laureate that I read was Paul Samuelson's economics textbook. Over time, I recovered sufficiently to read other economics books by other Nobel awardees. All these were readable enough...researched, written, rewritten, edited, etc. to prepare them for public consumption. This collection of Richard Feynman's letters was my first foray into "real" science. (opened only because it was in my book club's batting order this year) My only knowledge of Feynman owed to watching the occasional episode of The Big Bang Theory.
What an experience! With no editorial intervention between me and Feynman, it was an amazing read. His letters to his first, written while he worked at Los Almos and she was dying of cancer are incredible. His replies to the numerous letters of congratulations he received following his Nobel Prize reveal he ability to communicate with a remarkable range of people: President Johnson, a multitude of fellow scientists, and high school classmates.
A remarkable smorgasbord....sample it by all means!

What strikes me the most is that he never loses his sense of humor at his humbleness the older and more distinguished he gets. Gotta love Feynman.

As you can tell by the title, Perfectly Reasonable Deviations... is a collection of letters written by Nobel-Prize-winning physicist Richard P. Feynman. To me, it was intriguing, and there are letters here that would appeal to anyone, but I think you'd have to be (like me) a Feynman fan already, anxious to know everything about the man, to enjoy reading the book from cover to cover.

Anyone considering reading this book should first read Surely You're Joking, Mr. Feynman! Adventures of a Curious Character. After they enjoy that, they should try What Do You Care What Other People Think? Further Adventures of a Curious Character. If they also like that, then they might try Perfectly Reasonable Deviations.... Among titles not written by Feynman, I enjoyed the biography Genius: The Life and Science of Richard Feynman by James Gleick, and have heard very good things about No Ordinary Genius by Christopher Sykes, which daughter Michelle Feynman recommends in her introduction to Perfectly Reasonable Deviations.... If, after reading those, one still wants more, the letters will be waiting here.

Truly worth reading, and the last sentence made me cry. I love thinking about the fact that Richard Feynman had a perfectly average IQ. It was all about passion and hard work for him.

This is different from other Feynman books, read the letters, true gem!
