This Brief presents an historical investigation into the reaction between ferric ions and thiocyanate ions, which has been viewed in different ways throughout the last two centuries. Historically, the reaction was used in chemical analysis and to highlight the nature of chemical reactions, the laws of chemistry, models and theories of chemistry, chemical nomenclature, mathematics and data analysis, and instrumentation, which are important ingredients of what one might call the nature of chemistry. Using the history of the iron(III) thiocyanate reaction as a basis, the book’s main objective is to explore how chemistry develops its own knowledge base; how it assesses the reliability of that base; and how some important tools of the trade have been brought to bear on a chemical reaction to achieve understanding, a worthwhile goal of any historical investigation.
From the late fifteenth to the nineteenth centuries, the Hispanic Monarchy was one of the largest and most diverse political communities known in history. At its apogee, it stretched from the Castilian plateau to the high peaks of the Andes; from the cosmopolitan cities of Seville, Naples, or Mexico City to Santa Fe and San Francisco; from Brussels to Buenos Aires and from Milan to Manila. During those centuries, Spain left its imprint across vast continents and distant oceans contributing in no minor way to the emergence of our globalised era. This was true not only in an economic sense-the Hispano-American silver peso transported across the Atlantic and the Pacific by the Spanish fleets wa...
Twelve studies by eminent art historian James S. Ackerman. This collection contains studies written by art historian James Ackerman over the past decade. Whereas Ackerman's earlier work assumed a development of the arts as they responded to social, economic, political, and cultural change, his recent work reflects the poststructural critique of the presumption of progress that characterized Renaissance and modernist history and criticism. In this book he explores the tension between the authority of the past—which may act not only as a restraint but as a challenge and stimulus—and the potentially liberating gift of invention. He examines the ways in which artists and writers on art have ...
While the origin of trans-pacific contact between Asia and the New World can be traced as far back as the pre-Columbian period, it was not until the fifteenth century that communication across the Pacific became constant. Despite this history, the myriad encounters that constitute the basic contours of transpacific studies have often been overshadowed by the traditional emphasis on transatlantic studies. In addition, although socio-political ties between Asia and Latin America have drawn attention among politicians and economists in recent years, there continues to be a critical void in the studies of literary, cultural, and historical relations between the two regions. This book challenges ...
