Don't you have time to think?

Richard Feynman was one of the most inspirational men of our times.

He won the Nobel Prize, wrote equations on napkins in strip joints, cracked safes for fun while working on the atom bomb, upset those in authority, and touched countless lives.

He also wrote hundreds of witty, eccentric, and moving letters to his family, friends, 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, blunt rebuttals to journalists to poignant exchanges with his first wife as she suffered from tuberculosis, they will introduce you to a unique person whose wisdom and lust for life inspired all those who came into his orbit.
