FULL VOLUME 1st EDITION OF THREE LANDMARK PAPERS, each of seminal import in the history of physics. FEYNMAN'S "Forces in molecules" is the first edition of Feynman's undergraduate thesis, the paper that began to establish his name in physics. Published when he was just twenty-one, his work here a fundamental discovery "that has played an important role in theoretical chemistry and condensed matter physics" (Selected Papers, p. 1). This extraordinary work documents the first steps in original research of one of the most brilliant minds of the twentieth century. Feynman showed in this paper that "the force on an atom's nucleus is no more or less than the electrical force from the surrounding field of charged electrons - the electrostatic force. Once the distribution of charge has been calculated quantum mechanically, then from that point forward quantum mechanics disappears from the picture. The problem becomes classical; the nuclei can be treated as static points of mass and charge. Feynman's… Ler mais
