More than 100,000 copies of the first edition of Knowledge and Wonder have been sold, both in the U.S. and abroad. Written expressly for the general reader and beginning science student, the book describes our present scientific understanding of natural phenomena and the universality of that understanding and its human significance.

Tht development of the concept of subatomic particles is traced from the atom to the mesons and nucleons. The roles of the quantum theory and of the concept of symmetry are discussed, the significance of the research into subatomic particles for the physics is stressed. Resume L'evolution du terme particule elementaire est analysee, depuis I'atome jusqu'aux mesons et aux nucleons. Le roIe de Ia theorie des quanta ainsi que Ie terme symetrie font I'objet d'une discussion, tandis que I'auteur souligne l'importance de Ia recherche fondamentale relative aux particules elementaires pour Ia...

The second volume of this authoritative work traces the material outlined in the first, but in far greater detail and with a much higher degree of sophistication. The authors begin with the theory of the electromagnetic interaction, and then consider hadronic structure, exploring the accuracy of the quark model by examining the excited states of baryons and mesons. They introduce the color variable as a prelude to the development of quantum chromodynamics, the theory of the strong interaction, and go on to discuss the electroweak interaction--the broken symmetry of which they explain by the...

The University of Bologna and its Academy of Sciences, in collaboration with the Italian National Institute for Nuclear Physics and the Italian Physical Society, celebrated in 1998 the bicentenary of a great pioneer in the field of electric phenomena - Luigi Galvani, the father of macroelectricity. During these two centuries, the physics of electric phenomena has given rise first to the Maxwell equations, then to quantum electrodynamics, and finally to the synthesis of all reproducible phenomena, the "Standard Model." A cornerstone of the Standard Model is quantum chromodynamics (QCD), which...
