Este libro nos muestra como se fueron introduciendo en España durante el siglo XIX las ideas modernas acerca de la constitución de la materia.Vaquero Martínez, José M.

This introduction to Atomic and Molecular Physics explains how our present model of atoms and molecules has been developed over the last two centuries both by many experimental discoveries and, from the theoretical side, by the introduction of quantum physics to the adequate description of micro-particles. It illustrates the wave model of particles by many examples and shows the limits of classical description. The interaction of electromagnetic radiation with atoms and molecules and its potential for spectroscopy is outlined in more detail and in particular lasers as modern spectroscopic tools are discussed more thoroughly.Many examples and problems with solutions are offered to encourage readers to actively engage in applying and adapting the fundamental physics presented in this textbook to specific situations. Completely revised third edition with new sections covering all actual developments, like photonics, ultrashort lasers, ultraprecise frequency combs, free electron lasers, cooling and trapping of atoms, quantum optics and quantum information.

Atoms, Radiation, and Radiation Protection offers professionals and advanced students a comprehensive coverage of the major concepts that underlie the origins and transport of ionizing radiation in matter. Understanding atomic structure and the physical mechanisms of radiation interactions is the foundation on which much of the current practice of radiological health protection is based. The work covers the detection and measurement of radiation and the statistical interpretation of the data. The procedures that are used to protect man and the environment from the potential harmful effects of radiation are thoroughly described. Basic principles are illustrated with an abundance of worked examples that exemplify practical applications. Chapters include problem sets (with partial answers) and extensive tables and graphs for continued use as a reference work. This completely revised and enlarged third edition includes thorough updates of the material, including the latest recommendations of the ICRP and NCRP.

Atoms, Radiation, and Radiation ProtectionDiscover the keys to radiation protection in the fourth edition of this best-selling textbookA variety of atomic and sub-atomic processes, including alpha, beta, and gamma decay or electron ejection from inner atom shells, can produce ionizing radiation. This radiation can in turn produce environmental and biological effects both harmful including DNA damage and other impacts of so-called radiation sickness and helpful, including radiation treatment for cancerous tumors. Understanding the processes that generate radiation and the steps which can be taken to mitigate or direct its effects is therefore critical in a wide range of industries and medical subfields.For decades, Atoms, Radiation, and Radiation Protection has served as the classic reference work on the subject of ionizing radiation and its safeguards. Beginning with a presentation of fundamental atomic structure and the physical mechanisms which produce radiation, the book also includes thorough discussion of how radiation can be detected and measured, as well as guide-lines for interpreting radiation statistics and detailed analysis of protective measures, both individual and environmental. Now updated by a new generation of leading scholars and researchers, Atoms, Radiation, and Radiation Protection will continue to serve global scientific and industrial research communities.

Dentro de la historia de la ciencia el papel del mundo árabe no se limita a ser un mero transmisor de los antiguos conocimientos clásicos al mundo renacentista europeo, pues hemos de sumar a esta labor la gran cantidad de estudios y aportaciones originales que realizaron grandes cientificos que nada tuvieron que envidiar a ninguno de sus predecesores. Como no podia ser de otro modo, uno de los escenarios donde se desarrollo toda esta actividad fue al-Andalus, y uno de sus grandes protanistas, Azarquiel. Con este ilustre personaje como noble excusa, este libro es una introduccion a todas las aportaciones hispanoarabes que tuvieron su origen en la peninsula Iberica y que marcaron la ciencia y filosofia europeas en los siglos posteriores.

Mirar al cielo nocturno en busca del sentido de la existencia es un sello distintivo de nuestra humanidad. Desde la Edad de Piedra hemos contemplado las estrellas y nos hemos sentido hechizados por su majestuosidad y belleza. Clark explora esta fascinacion compartida por todos los seres humanos durante milenios y que nos ha moldeado como civilizacion y como individuos. La contemplacion del cielo nocturno ha dado forma a nuestra comprension cientifica del universo; nos ha ayudado a navegar por el mundo terrestre; nos ha dado un lugar para proyectar esperanzas y temores; ha servido de inspiracion a poetas, artistas y filosofos; nos ha revelado nuestro autentico origen y nos ha dado pistas sobre nuestro destino. Esta es la impresionante historia del universo y nuestro lugar dentro de el.
