Don't You Have Time to Think? collects the witty, eccentric and moving letters letters of Nobel Prize-winning physicist Richard P. Feynman.

Richard Feynman was no ordinary genius. Brilliant, free-spirited and irreverent, he upset those in authority, gave captivating lectures, wrote equations on napkins in strip joints and touched countless lives everywhere. He also wrote hundreds of letters to friends, family, critics, colleagues and devoted fans around the world.

Now these letters have been brought together for the first time. From down-to-earth advice to eager students to discussions of time travel and the atom bomb, and from blunt rebuttals to journalists to poignant exchanges with his first wife as she lay dying, they will introduce you to a unique person whose wisdom and lust for life inspired all those who came into his orbit.

'Nobel-winning physicist, expert bongo-player, safe-cracker and all-round genius, Feynman was, as this wonderful and inspiring collection records, also a champion letter-writer ... Witty, deadpan, warm ... some are unbearably poignant'
