Celestial delights : the best astronomical events through 2001 by Francis Reddy( Book )

6 editions published between 1992 and 2012 in English and held by 529 WorldCat member libraries worldwide

Celestial Delights is the essential 'TV Guide' for the sky. Through extensive graphics integrated with an eight-year-long calendar of sky events, it provides a look at "don't miss" sky events, mostly for naked-eye and binocular observing. It is organized by ease of observation - lunar phases and the brighter planets come first, with solar eclipses, the aurora, and comets coming later. This third edition also includes a hefty dose of sky lore, astronomical history, and clear overviews of current science. It provides a handy reference to upcoming naked-eye events, with information broken out in clear and simple diagrams and tables that are cross-referenced against a detailed almanac for each year covered. This book puts a variety of information all in one place, presents it in a friendly way that does not require prior in-depth astronomical knowledge, and provides the context and historical background for understanding events that astronomy software or web sites lack

Canto al Huaso, Canto al Pueblo: La Música y el Discurso Político de la Identidad Chilena durante los Años Sesenta y la Unidad Popular( )

1 edition published in 2004 in Undetermined and held by 1 WorldCat member library worldwide

La fuerte polarización de la política chilena durante los años sesenta y la Unidad Popular tiene un reflejo en las representaciones de la identidad nacional a través de la música. Usando la letra de canciones y entrevistas con músicologos y músicos, este ensayo examina el discurso politico presente en la música de este período. Primero, se describe la representación de una identidad nacional tradicional a través de la música de Los Huasos Quincheros. Luego, se analiza la formación de una identidad alternative en dos etapas: el desarrollo de una vision del país que reacciona a la imagen patronal y exclusive que presentan Los Huasos Quincheros; y la construcción de una identidad latinoamericana en el contexto de la guerra fría y el imperialismo politico y cultural de los Estados Unidos. Se examina la música de Violeta Parra y Victor Jara para explicar la primera etapa, luego se analiza la música de Inti Illimani, Illapu, y Quilapayún para demostrar el segundo proceso
