Download or read book Renaissance Vision from Spectacles to Telescopes written by Vincent Ilardi. This book was released on 2007. Available in PDF, EPUB and Kindle. Book excerpt: 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 Synopsis Francis Watkins and the Dollond Telescope Patent Controversy by : Brian Gee

Download or read book Francis Watkins and the Dollond Telescope Patent Controversy written by Brian Gee. This book was released on 2016-04-15. Available in PDF, EPUB and Kindle. Book excerpt: Francis Watkins was an eminent figure in his field of mathematical and optical instrument making in mid-eighteenth century London. Working from original documents, Brian Gee has uncovered the life and times of an optical instrument maker, who - at first glance - was not among the most prominent in his field. In fact, because Francis Watkins came from a landed background, the diversification of his assets enabled him to weather particular business storms - discussed in this book - where colleagues without such an economic cushion, were pushed into bankruptcy or forced to emigrate. He played an important role in one of the most significant legal cases to touch this profession, namely the patenting of the achromatic lens in telescopes. The book explains Watkins's origins, and how and why he was drawn into partnership with the famous Dollond firm, who at that point were Huguenot incomers. The patent for the achromatic telescope has never been satisfactorily explained in the literature, and the author has gone back to the original legal documents, never before consulted. He teases out the problems, lays out the evidence, and comes to some interesting new conclusions, showing the Dollonds as hard-headed and ruthless businessmen, ultimately extremely successful. The latter part of the book accounts for the successors of Francis Watkins, and their decline after over a century of successful business in central London.

Book Synopsis Paraphernalia by : Steven Connor

Download or read book Paraphernalia written by Steven Connor. This book was released on 2011-06-09. Available in PDF, EPUB and Kindle. Book excerpt: From keys and handkerchiefs to sweets and rubber bands, the curious objects we surround ourselves with, though often seemingly mundane, have a magical quality. Their surprising power to disturb, soothe, seduce or absorb give these quirky objects histories and meanings we rarely ponder. Yet we would be lost without them. Take bags, for example. Why do most women carry handbags, while men rely on pockets? Why do so many houses have bags of bags? And why do we 'let the cat out the bag' or 'give someone the sack'? What significance do our bags hold for us? In this highly imaginative and entertaining book, Steven Connor embarks on a historical, philosophical and linguistic journey that explores our relationships with the curious things with which we have a forgotten but daily intimacy.

Book Synopsis Sidereus Nuncius, or The Sidereal Messenger by : Galileo Galilei

Download or read book Sidereus Nuncius, or The Sidereal Messenger written by Galileo Galilei. This book was released on 2016-01-19. Available in PDF, EPUB and Kindle. Book excerpt: The “revolutionary, scintillating book” in which Galileo revealed his wondrous astronomical discoveries, with accompanying notes and historical context (Metascience). Galileo Galilei’s Sidereus Nuncius is arguably the most dramatic scientific book ever published. It announced new and unexpected phenomena in the heavens, “unheard of through the ages,” revealed by a mysterious new instrument. Galileo had ingeniously improved the rudimentary “spyglasses” that appeared in Europe in 1608, and in the autumn of 1609 he pointed his new instrument at the sky, discovering astonishing sights: mountains on the moon, fixed stars invisible to the naked eye, individual stars in the Milky Way, and four moons around the planet Jupiter. These discoveries changed the terms of the debate between geocentric and heliocentric cosmology and helped ensure the eventual acceptance of the Copernican planetary system. Albert Van Helden’s beautifully rendered and eminently readable translation is based on the Venice 1610 edition’s original Latin text. An introduction, conclusion, and copious notes place the book in its historical and intellectual context, and a new preface, written by Van Helden, highlights recent discoveries in the field, including the detection of a forged copy of Sidereus Nuncius, and new understandings about the political complexities of Galileo’s work.
