This collection from scientist and Nobel Peace Prize winner highlights the achievements of a man whose career reshaped the world's understanding of quantum electrodynamics.

Six Easy Pieces, taken from these famous Lectures on Physics, represent the most accessible material from the series.

In this career-spanning collection of letters, many published here for the first time, we are able to see this side of Feynman like never before.

"The whole thing was basically an experiment," Richard Feynman said late in his career, looking back on the origins of his lectures.

This is quintessential Feynman -- reflective, amusing, and ever enlightening.

In Six Not-So-Easy Pieces, taken from these famous Lectures on Physics, Feynman delves into one of the most revolutionary discoveries in twentieth-century physics: Einstein's theory of relativity.

"The whole thing was basically an experiment," Richard Feynman said late in his career, looking back on the origins of his lectures.

Nobel Laureate Feynman gave these lectures just once, to a group of Caltech undergraduates in 1961 and 1962, and these newly released recordings allow you to experience one of the Twentieth Century's greatest minds—as if you were right ...

In his stories, Feynman’s life shines through in all its eccentric glory—a combustible mixture of high intelligence, unlimited curiosity, and raging chutzpah. Included for this edition is a new introduction by Bill Gates.
