Download or read book Studies in Medieval Astronomy and Optics written by J.L. Mancha and published by Taylor & Francis. This book was released on 2023-07-21 with total page 325 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this selection of studies, J.L. Mancha explores aspects of the development of medieval optics and astronomy, including some medieval antecedents of the work of early modern astronomers. The articles deal with Latin, Hebrew and Arabic texts, and the process of translation and transmission of knowledge, and focus on three main themes. First, the theory and astronomical use of the pinhole camera in the 12th and 13th centuries; the texts edited here contain a solution to the problem of the formation of images cast by light through triangular apertures, equivalent to Kepler's, a description of the correct procedure for measuring solar apparent diameters using finite apertures, and a derivation of the Sun's eccentricity from its apparent diameters at apogee and perigee. Second, the characteristics of the Latin and Provençal versions of Levi ben Gerson's astronomical work, composed in collaboration with the author, as well as his tables and canons for finding syzygies and the mathematical methods used in the derivation of parameters. Third, different aspects of the survival of homocentric astronomy in the Middle Ages, especially al-Bitruji's model for trepidation and the technique for calculating the hippopede resulting from Eudoxan couples.

Download or read book Astronomy and Optics from Pliny to Descartes written by Bruce Eastwood and published by Routledge. This book was released on 1989 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: A principal concern of the author in writing these articles has been to elucidate the conceptual structures that underlie the scientific thought of the Middle Ages - the philosophical and cultural assumptions, presuppositions and motivations that determine the way concepts are formed and questions are answered. In the first group of articles Professor Eastwood focuses on astronomy in Latin Europe in the 5th-11th centuries, looking especially at the use, development and interpretation of diagrams in works on planetary motion. The following studies turn to optics and visual theory. They examine Robert Grosseteste's views on the rainbow, refraction and empirical knowledge, and study specific instances of how medieval thinkers, both in the Latin and Islamic worlds, reinterpreted and reformulated the concepts they had inherited.
Download or read book Measuring Shadows written by Raz Chen-Morris and published by Penn State Press. This book was released on 2016-03-31 with total page 263 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 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 or read book Influences written by Mary Quinlan-McGrath and published by University of Chicago Press. This book was released on 2013-02-20 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: Today 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 or read book Optics Astronomy and Logic written by A. I. Sabra and published by Routledge. This book was released on 1994 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: These articles discuss the appropriation of Greek science by scholars in the world of medieval Islam. After presenting the historiography of this process, the volume focuses on Ibn al-Haytham, one of the most influential figures of the 11th century, and on his contribution to the science of optics and the psychology of vision. The work then analyzes how Greek thought was developed in the Islamic world, based on studies of Euclid's geomotry and critiques of Ptolemaic astronomy. Finally, some articles consider the history of logic - Aristotelian syllogism and Avicenna's views on the subject matter of logic.
Download or read book Islamic Astronomical Tables written by Benno van Dalen and published by Taylor & Francis. This book was released on 2023-05-31 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume comprises nine articles on Islamic astronomy published since 1989 by Benno van Dalen. Van Dalen was the first historian of Islamic astronomy who made full use of the new possibilities of computers in the early 1990s. He implemented various statistical and numerical methods that can be used to determine the mathematical properties of medieval astronomical tables, and utilized these to obtain entirely new, until then unattainable historical results concerning the interdependence of individual tables and hence of entire astronomical works. His programmes for analysing tables, making sexagesimal calculations and converting calendar dates continue to be widely used. The five articles in the first part of this collection explain the principles of a range of statistical methods for determining unknown parameter values underlying astronomical tables and present extensive step-by-step examples for their use. The four articles in the second part provide extensive studies of materials in unpublished primary sources on Islamic astronomy that heavily depend on these methods. The volume is completed with a detailed index.
Download or read book The Light Ages The Surprising Story of Medieval Science written by Seb Falk and published by W. W. Norton & Company. This book was released on 2020-11-17 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: Named a Best Book of 2020 by The Telegraph, The Times, and BBC History Magazine An illuminating guide to the scientific and technological achievements of the Middle Ages through the life of a crusading astronomer-monk. "Falk’s bubbling curiosity and strong sense of storytelling always swept me along. By the end, The Light Ages didn’t just broaden my conception of science; even as I scrolled away on my Kindle, it felt like I was sitting alongside Westwyk at St. Albans abbey, leafing through dusty manuscripts by candlelight." —Alex Orlando, Discover Soaring Gothic cathedrals, violent crusades, the Black Death: these are the dramatic forces that shaped the medieval era. But the so-called Dark Ages also gave us the first universities, eyeglasses, and mechanical clocks. As medieval thinkers sought to understand the world around them, from the passing of the seasons to the stars in the sky, they came to develop a vibrant scientific culture. In The Light Ages, Cambridge science historian Seb Falk takes us on a tour of medieval science through the eyes of one fourteenth-century monk, John of Westwyk. Born in a rural manor, educated in England’s grandest monastery, and then exiled to a clifftop priory, Westwyk was an intrepid crusader, inventor, and astrologer. From multiplying Roman numerals to navigating by the stars, curing disease, and telling time with an ancient astrolabe, we learn emerging science alongside Westwyk and travel with him through the length and breadth of England and beyond its shores. On our way, we encounter a remarkable cast of characters: the clock-building English abbot with leprosy, the French craftsman-turned-spy, and the Persian polymath who founded the world’s most advanced observatory. The Light Ages offers a gripping story of the struggles and successes of an ordinary man in a precarious world and conjures a vivid picture of medieval life as we have never seen it before. An enlightening history that argues that these times weren’t so dark after all, The Light Ages shows how medieval ideas continue to color how we see the world today.

Download or read book Principles and Practices in Ancient Greek and Chinese Science written by G.E.R. Lloyd and published by Taylor & Francis. This book was released on 2023-07-28 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: From the 90 or so articles he has published in the last two decades Professor Lloyd has chosen fifteen of the most important and influential to be reprinted in this collection. They tackle a wide range of problems in ancient Greek and Chinese thought, focussing especially on science but including also medicine, mathematics, philosophy and mythology. Three common themes recur: the ancients' own concern with disciplinary boundaries, their engagement in polemics, and the heterogeneity of different traditions - cultivating different styles of reasoning with different results - in ancient science. Alongside papers that deal with technical issues in the interpretation of our sources, others raise strategic questions to do with the institutional framework of ancient science, the role of literacy in its development, and the underlying ontological and epistemological presuppositions of different groups of ancient investigators. The collection closes with a study in which Lloyd sets out how he sees the further comparative study of ancient science developing. Two of the articles appear here for the first time in English. The others are reprinted in their original form. Supplementary bibliographies are added referring to the most recent scholarship on the issues discussed.
Download or read book Islamic Astronomy and Geography written by David A. King and published by Routledge. This book was released on 2022-02-13 with total page 357 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume of 12 studies, mainly published during the past 15 years, begins with an overview of the Islamic astronomy covering not only sophisticated mathematical astronomy and instrumentation but also simple folk astronomy, and the ways in which astronomy was used in the service of religion. It continues with discussions of the importance of Islamic instruments and scientific manuscript illustrations. Three studies deal with the regional schools that developed in Islamic astronomy, in this case, Egypt and the Maghrib. Another focuses on a curious astrological table for calculating the length of life of any individual. The notion of the world centred on the sacred Kaaba in Mecca inspired both astronomers and proponents of folk astronomy to propose methods for finding the qibla, or sacred direction towards the Kaaba; their activities are surveyed here. The interaction between the mathematical and folk traditions in astronomy is then illustrated by an 11th-century text on the qibla in Transoxania. The last three studies deal with an account of the geodetic measurements sponsored by the Caliph al-Ma'mûn in the 9th century; a world-map in the tradition of the 11th-century polymath al-Bîrûnî, alas corrupted by careless copying; and a table of geographical coordinates from 15th-century Egypt.
