DOWNLOAD EBOOKSince the incorporation of scientific approach in tackling problems of optical instrumentation, analysis and design of optical systems constitute a core area of optical engineering. A large number of software with varying level of scope and applicability is currently available to facilitate the task. However, possession of an optical design software, per se, is no guarantee for arriving at correct or optimal solutions. The validity and/or optimality of the solutions depend to a large extent on proper formulation of the problem, which calls for correct application of principles and theories of optical engineering. On a different note, development of proper experimental setups for investigations in the burgeoning field of optics and photonics calls for a good understanding of these principles and theories. With this backdrop in view, this book presents a holistic treatment of topics like paraxial analysis, aberration theory, Hamiltonian optics, ray-optical and wave-optical theories of image formation, Fourier optics, structural design, lens design optimization, global optimization etc. Proper stress is given on exposition of the foundations. The proposed book is designed to provide adequate material for ‘self-learning’ the subject. For practitioners in related fields, this book is a handy reference. Foundations of Optical System Analysis and Synthesis provides A holistic approach to lens system analysis and design with stress on foundations Basic knowledge of ray and wave optics for tackling problems of instrumental optics Proper explanation of approximations made at different stages Sufficient illustrations for facilitation of understanding Techniques for reducing the role of heuristics and empiricism in optical/lens design A sourcebook on chronological development of related topics across the globe This book is composed as a reference book for graduate students, researchers, faculty, scientists and technologists in R & D centres and industry, in pursuance of their understanding of related topics and concepts during problem solving in the broad areas of optical, electro-optical and photonic system analysis and design.

DOWNLOAD EBOOKIn Measuring Shadows, Raz Chen-Morris demonstrates that a close study of Kepler’s Optics is essential to understanding his astronomical work and his scientific epistemology. He explores Kepler’s radical break from scientific and epistemological traditions and shows how the seventeenth-century astronomer posited new ways to view scientific truth and knowledge. Chen-Morris reveals how Kepler’s ideas about the formation of images on the retina and the geometrics of the camera obscura, as well as his astronomical observations, advanced the argument that physical reality could only be described through artificially produced shadows, reflections, and refractions. Breaking from medieval and Renaissance traditions that insisted upon direct sensory perception, Kepler advocated for instruments as mediators between the eye and physical reality, and for mathematical language to describe motion. It was only through this kind of knowledge, he argued, that observation could produce certainty about the heavens. Not only was this conception of visibility crucial to advancing the early modern understanding of vision and the retina, but it affected how people during that period approached and understood the world around them.

DOWNLOAD EBOOKToday few would think of astronomy and astrology as fields related to theology. Fewer still would know that physically absorbing planetary rays was once considered to have medical and psychological effects. But this was the understanding of light radiation held by certain natural philosophers of early modern Europe, and that, argues Mary Quinlan-McGrath, was why educated people of the Renaissance commissioned artworks centered on astrological themes and practices. Influences is the first book to reveal how important Renaissance artworks were designed to be not only beautiful but also—perhaps even primarily—functional. From the fresco cycles at Caprarola, to the Vatican’s Sala dei Pontefici, to the Villa Farnesina, these great works were commissioned to selectively capture and then transmit celestial radiation, influencing the bodies and minds of their audiences. Quinlan-McGrath examines the sophisticated logic behind these theories and practices and, along the way, sheds light on early creation theory; the relationship between astrology and natural theology; and the protochemistry, physics, and mathematics of rays. An original and intellectually stimulating study, Influences adds a new dimension to the understanding of aesthetics among Renaissance patrons and a new meaning to the seductive powers of art.

DOWNLOAD EBOOKDuring the late thirteenth and early fourteenth centuries a group of monks with occult interests donated what became a remarkable collection of more than thirty magic texts to the library of the Benedictine abbey of St. Augustine’s in Canterbury. The monks collected texts that provided positive justifications for the practice of magic and books in which works of magic were copied side by side with works of more licit genres. In Magic in the Cloister, Sophie Page uses this collection to explore the gradual shift toward more positive attitudes to magical texts and ideas in medieval Europe. She examines what attracted monks to magic texts, in spite of the dangers involved in studying condemned works, and how the monks combined magic with their intellectual interests and monastic life. By showing how it was possible for religious insiders to integrate magical studies with their orthodox worldview, Magic in the Cloister contributes to a broader understanding of the role of magical texts and ideas and their acceptance in the late Middle Ages.

DOWNLOAD EBOOKA Cultural History of Color in the Medieval Age covers the period 500 to 1400. The medieval age saw an extraordinary burst of color - from illuminated manuscripts and polychrome sculpture to architecture and interiors, and from enamelled and jewelled metalwork to colored glass and the exquisite decoration of artefacts. Color was used to denote affiliation in heraldry and social status in medieval clothes. Color names were created in various languages and their resonance explored in poems, romances, epics, and plays. And, whilst medieval philosophers began to explain the rainbow, theologians and artists developed a color symbolism for both virtues and vices. Color shapes an individual's experience of the world and also how society gives particular spaces, objects, and moments meaning. The 6 volume set of the Cultural History of Color examines how color has been created, traded, used, and interpreted over the last 5000 years. The themes covered in each volume are color philosophy and science; color technology and trade; power and identity; religion and ritual; body and clothing; language and psychology; literature and the performing arts; art; architecture and interiors; and artefacts. Carole P. Biggam is Honorary Senior Research Fellow in English Language and Linguistics at the University of Glasgow, UK. Kirsten Wolf is Professor of Old Norse and Scandinavian Linguistics at the University of Wisconsin-Madison, USA. Volume 2 in the Cultural History of Color set. General Editors: Carole P. Biggam and Kirsten Wolf The Cultural Histories Series A Cultural History of Color is part of The Cultural Histories Series.

DOWNLOAD EBOOKThis book argues that we can only understand transformations of nature studies in the Scientific Revolution if we take seriously the interaction between practitioners (those who know by doing) and scholars (those who know by thinking). These are not in opposition, however. Theory and practice are end points on a continuum, with some participants interested only in the practical, others only in the theoretical, and most in the murky intellectual and material world in between. It is this borderland where influence, appropriation, and collaboration have the potential to lead to new methods, new subjects of enquiry, and new social structures of natural philosophy and science. The case for connection between theory and practice can be most persuasively drawn in the area of mathematics, which is the focus of this book. Practical mathematics was a growing field in early modern Europe and these essays are organised into three parts which contribute to the debate about the role of mathematical practice in the Scientific Revolution. First, they demonstrate the variability of the identity of practical mathematicians, and of the practices involved in their activities in early modern Europe. Second, readers are invited to consider what practical mathematics looked like and that although practical mathematical knowledge was transmitted and circulated in a wide variety of ways, participants were able to recognize them all as practical mathematics. Third, the authors show how differences and nuances in practical mathematics typically depended on the different contexts in which it was practiced: social, cultural, political, and economic particularities matter. Historians of science, especially those interested in the Scientific Revolution period and the history of mathematics will find this book and its ground-breaking approach of particular interest.

DOWNLOAD EBOOKThere are no clear demarcation lines between magic, astrology, necromancy, medicine, and even sciences in the pre-modern world. Under the umbrella term 'magic,' the contributors to this volume examine a wide range of texts, both literary and religious, both medical and philosophical, in which the topic is discussed from many different perspectives. The fundamental concerns address issue such as how people perceived magic, whether they accepted it and utilized it for their own purposes, and what impact magic might have had on the mental structures of that time. While some papers examine the specific appearance of magicians in literary texts, others analyze the practical application of magic in medical contexts. In addition, this volume includes studies that deal with the rise of the witch craze in the late fifteenth century and then also investigate whether the Weberian notion of disenchantment pertaining to the modern world can be maintained. Magic is, oddly but significantly, still around us and exerts its influence. Focusing on magic in the medieval world thus helps us to shed light on human culture at large.

DOWNLOAD EBOOKThis book presents twenty chapters by experts in their fields, providing a thorough and interdisciplinary overview of the theory and practice of magic in the West. Its chronological scope extends from the Ancient Near East to twenty-first-century North America; its objects of analysis range from Persian curse tablets to US neo-paganism. For comparative purposes, the volume includes chapters on developments in the Jewish and Muslim worlds, evaluated not simply for what they contributed at various points to European notions of magic, but also as models of alternative development in ancient Mediterranean legacy. Similarly, the volume highlights the transformative and challenging encounters of Europeans with non-Europeans, regarding the practice of magic in both early modern colonization and more recent decolonization.
