Esta serie de Introducción a la Física del M.I.T., una producción directa del trabajo del Centro, está destinada a ser un conjunto de textos que globalmente abarquen las áreas principales de la Física basica. La serie pretende destacar la interaccion de la experiencia y la intuicion en el desarrollo de las teorias fisicas. Los libros de la misma proporcionan una variedad de bases posibles para los cursos de introduccion, desde aquellas que destacan fundamentalmente la Fisica clasica hasta aquellas que incluyen una cantidad considerable de Fisica atomica y cuantica. Los diversos tomos pretenden ser compatibles en nivel y estilo de tratamiento, pero en ningun momento se han concebido como una enciclopedia homogenea; por el contrario, cada uno de los libros se han diseñado de modo que sea razonablemente individual en muchos planes de estudio.

El desarrollo ininterrumpido de la Física teórica y la constante ampliación del campo de sus aplicaciones imponen nuevos y nuevos requisitos a los manuales y obras de texto dedicados a ella.Los métodos de investigacion fisica experimentales y teoricos han penetrado en toda una serie de disciplinas cinetificas afines (Quimica fisica, Biofisica, Geofisica, Astrofisica, etc.) y en la tecnica (Fisica de los metales y Metalurgia fisica, Fisica del calor, Electrotecnia y Radiotecnia, tecnica de los computadores, construccion de instrumentos de precision, etc.) Las personas que trabajan en estos campos de la Ciencia y de la Tecnica tambien necesitan, por lo tanto, un minimo de concimientos de Fisica teorica.

El libro tiene tres partes de distinto carácter: (a) La primera está redactada como un curso elemental para un primer ciclo de la licenciatura en Física, pero su contenido es más completo que el de otros textos de este nivel.(b) La segunda parte esta constituida por 253 ejercicios resueltos y comentados que muestran como deben resolverse los problemas con el metodo caracteristico de este texto. (c) La tercera parte esta constituida por 17 apendices divididos en cuatro grupos de distinto caracter.Se trata con ellos de mostrar a los estudiantes que la Termodinamica no es solo lo que se presenta en el cuerpo del texto, sino que se extiende tambien a casos diferentes de los vistos en el.

Volume 18 in the CGL-Studies series, entitled "Environmental Policy and Landscape Architecture", is the result of an international symposium held in Jerusalem in March 2011 which was organised by the Van Leer Jerusalem Institute in collaboration with the Centre of Garden Art and Landscape Architecture. The symposium focused on how the many different facets of landscape architecture could help towards solving environmental problems. Sustainable Development and Landscaping, Environmental Policy and the Contribution of Landscape Architecture at a Local Level, Designing Public Open Spaces and Social Sustainability, Spatial Planning and Landscape Architecture in Israel/Palestine, and Water and Soil: Crisis and Conservation are the key chapters in this volume. The authors address a wide range of issues including the significance of religions in ideas about environmentalism in historical and current debates, how Palestinian society can meet challenges posed by the dynamic development of urban structures through capacity building in landscape architecture, and economically meaningful strategies for soil conservation in arable fields as part of agricultural sustainability in semi-arid areas. A key objective of the symposium was also to determine opportunities for cooperation in the field of environment and landscaping for Israelis, Palestinians, Muslims, Jews and Christians in a region marked by huge tension and conflicts. The authors are scholars of various disciplines such as landscape architecture, urban planning, technology assessment, philosophy of science, environmental communication and ecology, and come from Israel, Palestine, USA, Norway and Germany.
