Surely you are joking Mr. Feynman

"Surely you are joking, Mr. Feynman" is a memoir of Nobel Prize winning physicist Richard Feynman written by a close friend based on stories he heard from Richard Feynman during their time together.

This book has not much to do with science but showcases Richard Feynman's multiple interests like in samba music, languages, safe-cracking etc. It's a fairly light reading and gives you an idea of the kind of person he was outside his lab.
