Brossura. Condizione: come nuovo. Condizione sovraccoperta: ottimo. prima edizione. The present volume is a collection of papers presented in Turin and in Rome during the third week of September 1969. They were prepared for an international conference celebrating the centennial of the discovery by Dimitri Ivanovich Mendeleev of the periodic system of the elements. The topics covered in the different papers are for the most part centered upon the role that the notions of periodicity and symmetry have had and continue to have in chemistry as well as in atomic, nuclear and elementary particles physics. The different contributions have been arranged according to an historical order. The papers dealing with atoms come first, then follow those dedicated to some aspects of nuclear dynamics and finally those dealing with the rich world of subnuclear particles. By no means can it be said that the subject has been explored with a balanced treatment of its parts. The organizers of the conference, alone responsible for these shortcomings, were well aware of their difficult task. Yet, the masterful presentations of many viewpoints by the distinguished scholars who contributed to this volume represent a body of knowledge of lasting value and great interest.

1st Edition. RARE FIRST EDITION, FIRST ISSUE of the INTRODUCTION OF THE YANG-MILLS QUANTUM MECHANICAL THEORY. Also included in this volume is the paper in which Gell-Mann and Goldberger introduce crossing symmetry. "It is shown that an exact calculation in quantum field theory gives results identical with those obtained by classical methods or else by use of the Dirac equation with an anomalous Pauli moment" (Abstract). Also included is an important paper by Gian Carlo Wick introducing Wick's Theorem, a method of reducing high-order derivatives to a combinatorics problem used extensively in quantum field theory. YANG-MILLS THEORY: The Yang-Mills theory is now the foundation of most of elementary particle theory; it is the mathematical foundation underlying "three of the four fundamental forces of nature that physicists succeeded in unifying in the last half of the 20th century: electromagnetism, the 'weak force' responsible for radioactive decay, and the 'strong force' responsible for holding the nuclei of atoms together" (Gale, World of Mathematics Summary). Yang and Mills proposed a tensor equation that relies on a quantum mechanical property called the 'mass gap.' "The laws of quantum physics stand to the world of elementary particles in the way that Newton's laws of classical mechanics stand to the macroscopic world. Almost half a century ago, Yang and Mills introduced a remarkable new framework to describe elementary particles using structures that also occur in geometry. The successful use of Yang-Mills theory (now widely tested and affirmed) to describe the strong interactions of elementary particles depends on a subtle quantum mechanical property called the "mass gap:" the quantum particles have positive masses, even though the classical waves travel at the speed of light. This property has been discovered by physicists from experiment and confirmed by computer simulations, but it still has not been understood from a theoretical point of view. Progress in establishing the existence of the Yang-Mills theory and a mass gap and will require the introduction of fundamental new ideas both in physics and in mathematics" (Clay Mathematics Institute). CONDITION & DETAILS: Lancaster: American Physical Society. Volume 96. 4to. This volume includes the October to December issues of 1954, six in total.

The journal papers are bright and very clean throughout. Very good + condition.

4 SS. auf 2 Bll. Gr.-4to. An den Physiker und Nobelpreisträger Isidor Isaac Rabi (18981988): I wrote to you some time ago about a possible way of measuring nuclear spins values by the resonance method. I am afraid you found my suggestion a little naive, as I am not in a position to appreciate all complications which may arise in the interpretation of the experiments. Since, however, the process of exchanging opinions across the ocean is rather slow, I have been using this time to learn something more about the problem from the purely mathematical point of view, which is very narrow, of course. Here I send you a small diagram [.]". Auf Briefpapier mit gedr. Briefkopf der Universität Padua; Bl. 1 horizontal durchrissen; mit kleinen Randläsuren.

3 SS. auf Doppelblatt. 4to. An den Physiker und Nobelpreisträger Isidor Isaac Rabi (18981988): Dr. Segrè informs me that you are planning experiments on the N2-molecule and that you would appreciate some theoretical prediction on the value to be expected for its rotational magnetic moment. When the H2-case was being discussed, a general formula for the moment was given, and a rough numerical evaluation was made for hydrogen. Unfortunately, the numerical work in the case of nitrogen would be enormous, or better to say impossible, since the necessary wave-functions are not known. The information which I can give you is therefore very scanty [.]". Auf Briefpapier mit gedr. Briefkopf der Universität Rom und mit einem kleinen Randeinriß.
