Edgerton shows how linear perspective emerged in early fifteenth-century Florence out of an artistic and religious context in which devout Christians longed for divine presence in their daily lives and ultimately undermined medieval Christian cosmology.

The Hubble Space Telescope has produced the most stunning images of the cosmos humanity has ever seen. It has transformed our understanding of the universe around us, revealing new information about its age and evolution, the life cycle of stars, and the very existence of black holes, among other startling discoveries. But it took an amazing amount of work and perseverance to get the first space telescope up and running. The Universe in a Mirror tells the story of this telescope and the visionaries responsible for its extraordinary accomplishments. Robert Zimmerman takes readers behind the scenes of one of the most ambitious scientific instruments ever sent into space. After World War II, astronomer Lyman Spitzer and a handful of scientists waged a fifty-year struggle to build the first space telescope capable of seeing beyond Earth's atmospheric veil. Zimmerman shows how many of the telescope's advocates sacrificed careers and family to get it launched, and how others devoted their lives to Hubble only to have their hopes and reputations shattered when its mirror was found to be flawed. This is the story of an idea that would not die--and of the dauntless human spirit. Illustrated with striking color images, The Universe in a Mirror describes the heated battles between scientists and bureaucrats, the perseverance of astronauts to repair and maintain the telescope, and much more. Hubble, and the men and women behind it, opened a rare window onto the universe, dazzling humanity with sights never before seen. This book tells their remarkable story. A new afterword updates the reader on the May 2009 Hubble service mission and looks to the future of astronomy, including the prospect of a new space telescope to replace Hubble.

Picture, if you can, a world without glass. There would be no microscopes or telescopes, no sciences of microbiology or astronomy. People with poor vision would grope in the shadows, and planes, cars, and even electricity probably wouldn't exist. Artists would draw without the benefit of three-dimensional perspective, and ships would still be steered by what stars navigators could see through the naked eye. In Glass: A World History, Alan Macfarlane and Gerry Martin tell the fascinating story of how glass has revolutionized the way we see ourselves and the world around us. Starting ten thousand years ago with its invention in the Near East, Macfarlane and Martin trace the history of glass and its uses from the ancient civilizations of India, China, and Rome through western Europe during the Renaissance, Enlightenment, and Industrial Revolution, and finally up to the present day. The authors argue that glass played a key role not just in transforming humanity's relationship with the natural world, but also in the divergent courses of Eastern and Western civilizations. While all the societies that used glass first focused on its beauty in jewelry and other ornaments, and some later made it into bottles and other containers, only western Europeans further developed the use of glass for precise optics, mirrors, and windows. These technological innovations in glass, in turn, provided the foundations for European domination of the world in the several centuries following the Scientific Revolution. Clear, compelling, and quite provocative, Glass is an amazing biography of an equally amazing subject, a subject that has been central to every aspect of human history, from art and science to technology and medicine.

This book provides a step-by-step guide of how anyone can capture and produce beautiful astronomical images, for beginners and professionals alike.

From #1 New York Times bestselling author Dava Sobel, the "inspiring" (People), little-known true story of women's landmark contributions to astronomy A New York Times Book Review Notable Book of 2017 Named one of the best books of the year by NPR, The Economist, Smithsonian, Nature, and NPR's Science Friday Nominated for the PEN/E.O. Wilson Literary Science Writing Award "A joy to read.” —The Wall Street Journal In the mid-nineteenth century, the Harvard College Observatory began employing women as calculators, or “human computers,” to interpret the observations their male counterparts made via telescope each night. At the outset this group included the wives, sisters, and daughters of the resident astronomers, but soon the female corps included graduates of the new women's colleges—Vassar, Wellesley, and Smith. As photography transformed the practice of astronomy, the ladies turned from computation to studying the stars captured nightly on glass photographic plates. The “glass universe” of half a million plates that Harvard amassed over the ensuing decades—through the generous support of Mrs. Anna Palmer Draper, the widow of a pioneer in stellar photography—enabled the women to make extraordinary discoveries that attracted worldwide acclaim. They helped discern what stars were made of, divided the stars into meaningful categories for further research, and found a way to measure distances across space by starlight. Their ranks included Williamina Fleming, a Scottish woman originally hired as a maid who went on to identify ten novae and more than three hundred variable stars; Annie Jump Cannon, who designed a stellar classification system that was adopted by astronomers the world over and is still in use; and Dr. Cecilia Helena Payne, who in 1956 became the first ever woman professor of astronomy at Harvard—and Harvard’s first female department chair. Elegantly written and enriched by excerpts from letters, diaries, and memoirs, The Glass Universe is the hidden history of the women whose contributions to the burgeoning field of astronomy forever changed our understanding of the stars and our place in the universe.

A concise introduction to lens design, including the fundamental theory, concepts, methods and tools used in the field. Covering all the essential concepts and providing suggestions for further reading at the end of each chapter, this book is an essential resource for graduate students working in optics and photonics.
