Today we are all familiar with the iconic pictures of the nebulae produced by the Hubble Space Telescope’s digital cameras. But there was a time, before the successful application of photography to the heavens, in which scientists had to rely on handmade drawings of these mysterious phenomena. Observing by Hand sheds entirely new light on the ways in which the production and reception of handdrawn images of the nebulae in the nineteenth century contributed to astronomical observation. Omar W. Nasim investigates hundreds of unpublished observing books and paper records from six nineteenth-century observers of the nebulae: Sir John Herschel; William Parsons, the third Earl of Rosse; William Lassell; Ebenezer Porter Mason; Ernst Wilhelm Leberecht Tempel; and George Phillips Bond. Nasim focuses on the ways in which these observers created and employed their drawings in data-driven procedures, from their choices of artistic materials and techniques to their practices and scientific observation. He examines the ways in which the act of drawing complemented the acts of seeing and knowing, as well as the ways that making pictures was connected to the production of scientific knowledge. An impeccably researched, carefully crafted, and beautifully illustrated piece of historical work, Observing by Hand will delight historians of science, art, and the book, as well as astronomers and philosophers.
“Observing the Sun” is for amateur astronomers at all three levels: beginning, intermediate, and advanced. The beginning observer is often trying to find a niche or define a specific interest in his hobby, and the content of this book will spark that interest in solar observing because of the focus on the dynamics of the Sun. Intermediate and advanced observers will find the book invaluable in identifying features (through photos, charts, diagrams) in a logical, orderly fashion and then guiding the observer to interpret the observations. Because the Sun is a dynamic celestial body in constant flux, astronomers rarely know for certain what awaits them at the eyepiece. All features of the Sun are transient and sometimes rather fleeting. Given the number of features and the complex life cycles of some, it can be a challenging hobby. “Observing the Sun” provides essential illustrations, charts, and diagrams that depict the forms and life cycles of the numerous features visible on the Sun.
Written by an experienced and well-known lunar observer, this is a hands-on primer for the aspiring observer of the Moon. Whether you are a novice or are already experienced in practical astronomy, you will find plenty in this book to help you raise your game to the next level and beyond. In this thoroughly updated second edition, the author provides extensive practical advice and sophisticated background knowledge of the Moon and of lunar observation. It incorporates the latest developments in lunar imaging techniques, including digital photography, CCD imaging and webcam observing, and essential advice on collimating all common types of telescope. Learn what scientists have discovered about our Moon, and what mysteries remain still to be solved. Find out how you can take part in the efforts to solve these mysteries, as well as enjoying the Moon's spectacular magnificence for yourself!
An Actor's Task provides a framework for studying the dual arts of acting: inhabiting a character both physically and psychologically. Actors at all levels can use this book to explore, develop, and review the sensory tools and training that enable them to be the best versions of themselves and, ultimately, to bring that understanding of "self" to their art. Innovative new exercises and selected classics--updated for today's students--comprise more than 100 exercises. Introductions to each exercise explain its aims and benefits. Clear step-by-step prompts provide guidance. Debriefing sections engage actors in reflection on what they have experienced and learned. This inspired text is equally suited to classroom use and individual study.
The astronomer’s observing chair as both image and object, and the story it tells about a particular kind of science and a particular view of history. The astronomer’s chair is a leitmotif in the history of astronomy, appearing in hundreds of drawings, prints, and photographs from a variety of sources. Nineteenth-century stargazers in particular seemed eager to display their observing chairs—task-specific, often mechanically adjustable observatory furniture designed for use in conjunction with telescopes. But what message did they mean to send with these images? In The Astronomer’s Chair, Omar W. Nasim considers these specialized chairs as both image and object, offering an original framework for linking visual and material cultures. Observing chairs, Nasim ingeniously argues, showcased and embodied forms of scientific labor, personae, and bodily practice that appealed to bourgeois sensibilities. Viewing image and object as connected parts of moral, epistemic, and visual economies of empire, Nasim shows that nineteenth-century science was represented in terms of comfort and energy, and that “manly” postures of Western astronomers at work in specialized chairs were contrasted pointedly with images of “effete” and cross-legged “Oriental” astronomers. Extending his historical analysis into the twentieth century, Nasim reexamines what he argues to be a famous descendant of the astronomer’s chair: Freud’s psychoanalytic couch, which directed observations not outward toward the stars but inward toward the stratified universe of the psyche. But whether in conjunction with the mind or the heavens, the observing chair was a point of entry designed for specialists that also portrayed widely held assumptions about who merited epistemic access to these realms in the first place.
