Renaissance Vision from Spectacles to Telescopes


Book Description

Deals with the history of eyeglasses from their invention in Italy ca. 1286 to the appearance of the telescope three cent. later. "By the end of the 16th cent. eyeglasses were as common in western and central Europe as desktop computers are in western developed countries today." Eyeglasses served an important technological function at both the intellectual and practical level, not only easing the textual studies of scholars but also easing the work of craftsmen/small bus. During the 15th cent. two crucial developments occurred: the ability to grind convex lenses for various levels of presbyopia and the ability to grind concave lenses for the correction of myopia. As a result, eyeglasses could be made almost to prescription by the early 17th cent. Illus.

Book Description




Electromagnetic Wave Theory


Book Description

Taking a somewhat traditional viewpoint, this book begins with a review of stationary fields. Then, in a novel departure from many texts on EM theory, the author develops many of the essential ideas in wave propagation by treating purely scalar problems in one, two, and three dimensions. The loss in generality is later recovered when some of the same problems are addressed when vector solutions of Maxwell's equations are required.




The Lynx and the Telescope


Book Description

The Lynx and the Telescope challenges the traditional interpretation of a programmatic convergence between the visions of Galileo and Cesi’s Academy, while offering a new interpretation of the dynamics that led to the condemnation of Galileo in 1633.




The Optics of Giambattista Della Porta (ca. 1535–1615): A Reassessment


Book Description

This volume contains essays that examine the optical works of Giambattista Della Porta, an Italian natural philosopher during the Scientific Revolution. Coverage also explores the science and technology of early modern optics. Della Porta's groundbreaking book, Magia Naturalis (Natural Magic), includes a prototype of the camera. Yet, because of his obsession with magic, Della Porta's scientific achievements are often forgotten. As the contributors argue, his work inspired such great minds as Johanes Kepler and Francis Bacon. After reading this book, researchers, historians, and students will have a better appreciation of this influential scientist. They will also gain a greater understanding of an important period in the history of optics. Readers will learn about Della Porta's experimental method, a process governed by the protocols, aims, and theoretical assumptions of natural magic. Coverage also discusses the material properties and limitations of optical technology in the early 17th century, based on a recently discovered Dutch spyglass. It also demonstrates how diagrams were instrumental in the discovery of the sine law of refraction. In addition, the book includes an in-depth analysis of previously untranslated Latin sources. This makes the material useful to historians of optics unfamiliar with the language. More than 70 illustrations complement the text.




The Origins of the Telescope


Book Description

The origins of the telescope have been discussed and debated since shortly after the instrument's appearance in The Hague in 1608. Civic and national pride have led local dignitaries, popular writers, and numerous scholars to search the archives and to construct sharply divergent histories. Did the honor of the invention belong to the Dutch, to the Italians, to the English, or to the Spanish? And if the city of Middelburg in the Netherlands was, in fact, the cradle of the instrument, was the "true inventor" Hans Lipperhey or his rival Zacharias Jansen? Or was the instrument there before anyone knew it? Over the past several decades, a group of historians and scientists have sought out new documents, re-examined familiar ones, and tested early lenses and telescopes. This volume contains the proceedings of a symposium held in Middelburg in September 2008 to mark 400 years of the telescope. The essays in it, taken as a whole, present a new and convincing account of the origins of the instrument that changed mankind's vision of the universe.
