Richard Feynman, one of the greatest physicists of the 20th century and a winner of the Nobel Prize, died in February 1988. This is his last anecdotal autobiography in which he tells the story of the two people who most influenced his early years - his father, who taught him to think, and his first wife Arlene who taught him to love, even as she lay dying at an Albuquerque hospital while Feynman worked nearby on the atomic bomb at Los Alamos. There are also lighter moments which tell of his travels in Geneva, Trinidad, Greece and Japan. In the second part, Feynman gives a behind-the-scenes account of the investigation that followed the space shuttle Challenger's explosion in January 1986, showing the inner workings of the Rogers Commission, the official enquiry into the causes of the disaster, the confusion and misjudgement which plagued NASA and the moment when the cause of the Challenger disaster was revealed.
