Throughout his extraordinary career Richard Feynman wrote regularly to friends and family, to his fans around the world, and to colleagues eager for advice. This collection of his letters has been lovingly woven into a life story by his daughter Michelle Feynman. They provide a unique portrait of a man whose passion and commitment inspired all who were lucky enough to come within his orbit. Feynman's letters are direct and uncompromising; patient, thoughtful, always humourous, he challenges his readers to be true to themselves and not to accept conventional wisdom. He is also, in this, his personal correspondence, exceptionally entertaining.

Richard P. Feynman (1918-88) was one of this century's most brilliant theoretical physicists and original thinkers. In 1965 he won the Nobel Prize for his work in quantum electrodynamics.
