Nobel Prize-winning physicist Richard P. Feynman (1918-88) was that rarest of creatures—a towering scientific genius who could make himself understood by anyone, and who became as famous for the wit and wisdom of his popular lectures and writings as for his fundamental contributions to science. In these selections by his daughter, Feynman's playful intelligence is always evident, and in this treasure trove of ruminations and bon mots, he comments on art, childhood, family, imagination, politics, science, religion, and uncertainty. Also included here are fond recollections of Feynman by physicist Brian Cox and cellist Yo-Yo Ma.
