Richard Feynman is one of the most important physicists of the past century. Awarded the Nobel Prize in 1965 for his contributions to physics, in particular for his work with electrodynamic quantum physics, he created the famous diagrams that now carry his name and that represent one of the few intelligible points in the confusing world of elementary particle physics. He is also the author of a physics manual, comprised of several volumes, that covers the entirety of the discipline and is an authority throughout the world. This discussion of gravity presents a totally new perspective on the issue. Feynman is not content with merely explaining the Newtonian theory and the Einsteinian theory in his entertaining and unusual style. He proposes as well his own perspective on the phenomenon, motivated by a desire for unification of the physical forces which until now gravity has seemed to evade.

Richard Feynman (1918-1988), professor at the California Institute of Technology, received the Nobel Prize in Physics in 1965. He has also published with Odile Jacob Vous y comprenez quelque chose, Monsieur Feynman?, Leçons sur la physique, and his autobiography Vous voulez rire, Monsieur Feynman !
