An authoritative study of Gego, whose distinctive modernist practice sits at the intersection of architecture, design, and the visual arts This important book is the first extended study of the life and work of German-born Venezuelan artist Gertrude Goldschmidt (1912-94), known as Gego. In locating the artist's contribution to postwar art and her important place in the global conversations around modernity, Mónica Amor explores her intermedial practice as a model of cultural complexity at the "edge of modernity." In situating Gego's work alongside other local archives and against her European education and global reception, Amor offers a monographic model that complicates traditional approaches to history. She investigates the full range of Gego's work, including her furniture workshop, her teaching at schools of architecture and design, her seminal reticuláreas, and her lesser-known prints. Through rigorous archival research, formal analysis, theoretical relevance, and deep exploration of historical context, this essential book unpacks Gego's radical recasting of the modern sculptural project through her engagement with architecture, craft, and design pedagogy.

Is the solar system ordered? Or is it simply the result of random and chaotic accidents? This book takes the reader on a compelling and powerful journey of discovery, revealing the celestial spheres in their astonishingly complex patterns. Movements of the planets are found to correspond accurately with simple geometric figures and musical intervals, pointing to an exciting new perspective on the ancient idea of the "harmony of the spheres." Hartmut Warm's detailed presentation incorporates the distances, velocities, and periods of conjunction of the planets, as well as the rotations of the Sun, Moon, and Venus. Numerous graphics--including color plates--illustrate the extraordinary beauty of geometrical forms that result when the movements of several planets are viewed in relation to one another. Moreover, the author describes and analyzes concepts of the "music of the spheres," with special emphasis on Kepler's revolutionary ideas. The book also discusses current scientific beliefs about the origin of the universe and the solar system, enabling the reader to understand fully how this remarkable research supplements contemporary materialistic views of the cosmos. The appendix includes his mathematical and astronomical methods of calculation, as well as a detailed discussion of their accuracy and validity based on modern astronomical algorithms.

Das Verhältnis zwischen Öffentlichkeit und Religion ist einer der großen Klassiker der Geistesgeschichte, der bis heute nichts von seiner Bedeutung eingebüßt hat. Mit großer Regelmäßigkeit rekurrieren Soziologen und Politikwissenschaftler auf eine Rückkehr der Religionen in den öffentlichen Raum. Im Zuge von Säkularisierung, Globalisierung und Digitalisierung stehen moderne Öffentlichkeiten und Religionen in einem stetig komplexeren Netz wechselseitiger Transformation. Einen besonderen Kristallisationspunkt dieses intensiven Wechselverhältnisses bilden die beiden großen Schlüsselthemen öffentliche Bildung und universitäre Forschung. Die im vorliegenden Band versammelten Beiträge beleuchten schlaglichtartig einige ausgewählte Aspekte in diesem weiten Feld vom Ende des 18. Jahrhunderts bis in die Gegenwart. ******** The relationship between the public sphere and religion is one of the great classics of the history of humanities. To this day, it has lost none of its topicality. Sociologists and political scientists continue to refer with great frequency to a return of religions to the public sphere. In the course of secularization, globalization and digitalization, modern public spheres and religions find themselves in an increasingly complex web of mutual transformation. Public education and university research represent two key issues of this intensive interrelation. The contributions collected in the present volume illuminate selected aspects of this broad field from the end of the 18th century to the present.
