Los instrumentos de la ciencia ilustrada. Física experimental en los reales estudios de San Isidro de Madrid (1770-1835)

En esta obra, dedicada a explorar los significados del objeto científico educativo, se han contemplado diversos factores. Primero, se ha tenido en cuenta la influencia de las políticas educativas en el establecimiento de condiciones formales y materiales que permitieran la consolidación de un determinado modelo de enseñanza científico-técnica en España. Segundo, se ha examinado la influencia de la industria en las representaciones de la ciencia y de la técnica, las cuales circulaban junto con los instrumentos por diferentes países con patrones culturales análogos. A estos elementos...

Delineating the huge strides taken in cosmology in the past ten years, this much-anticipated second edition of Malcolm Longair's highly appreciated textbook has been extensively and thoroughly updated. It tells the story of modern astrophysical cosmology from the perspective of one of its most important and fundamental problems – how did the galaxies come about? Longair uses this approach to introduce the whole of what may be called "classical cosmology". What’s more, he describes how the study of the origin of galaxies and larger-scale structures in the Universe has provided us with...

This thesis (written in Spanish) presents the analysis, design and implementation of a four-quadrant power supply with high-frequency isolation, which is expected to be used to feed the low-energy correction magnet of a particle accelerator. In particle accelerator applications the magnetic field during beam acceleration may be either positive or negative, and true bipolar power converters are needed. The selected bipolar topology consists of a bidirectional three-phase to single-phase reduced matrix converter (RMC) with power factor correction and a bidirectional active rectifier. Main...

Charles Darwin spent the majority of his 1832-1833 voyage around the world in southern South America, and his early experiences in the Cape Horn region may have triggered his first ideas on human evolution. Darwin was not only a field naturalist, but also a scholar of the observations of the European explorers who preceded him. This book illuminates the foundations of Cape Horn’s natural history records as they oriented Darwin’s own explorations and his ideas on natural selection. Richly illustrated with maps and color photographs, this book also offers a guide to the sites visited by...
