Spectra Of Bright Southern Stars Photographed With The 13 Inch Boyden Telescope As A Part Of The Henry Draper Memorial

'Catchers of the Light' is a History of Astrophotography. It tells the true stories of the 46 pioneers who did most to master the art of celestial photography, as it was known during its early days; and whose efforts have made it possible for us to see the many magnificent pictures of the Universe featured in books, magazines and on the internet. In its TWO magnificent volumes is contained an unbelievable collection of tales of adventure, adversity and ultimate triumph and tells the uplifting stories of this small band of ordinary men and women, who did such extraordinary things; overcoming obstacles as diverse as war, poverty, cholera, death, very unfriendly cannibal natives and even exploding donkeys. It has been written with a no specific audience in mind - it is a book for anybody in fact - astronomers, photographers, historians, genealogists, art dealers, students, artists, doctors, farmers, builders, teachers & many more. If you like to read about the lives of special people - those who never give up - no matter what - and who succeed in achieving the seemingly impossible - then this is the book for you. This book of 1600 or so pages, with 1800 or more photographs/illustrations and over 2000 references/notes - represents the FIRST fully detailed and professionally researched book on the subject; and tells of the incredible lives of the pioneers of Astrophotography, each with their own incredible story to tell - they were the ‘Catchers of the Light’. Catchers of the Light is divided into ten Parts (I-X), each covering a specific aspect of the subject- I: Origins of Astrophotography; II: Lunar Astrophotography; III: Solar Astrophotography; IV: Solar System Astrophography; V: Deep Space Astrophotography; VI: Photographic Astronomical Spectroscopy; VII: Photographic Sky Surveys; VIII: Astrographs; IX: Modern Digital Age; X: Appendices.

Stars are the fundamental observable constituents of the Universe. They are the first objects we see in the night sky, they dominate the light produced in our own and other galaxies, and nucleosynthesis in stars produces all the elements heavier than helium. A knowledge of stars and their evolution is vital to understand other astrophysical objects from accreting black holes and galaxies to the Universe itself.The structure of a star can be described mathematically by differential equations derived from the principles of hydrodynamics, electromagnetic theory, thermodynamics, quantum mechanics, atomic and nuclear physics. The basic equations of a spherical star are derived in detail at an accessible level. The topics discussed include modes of energy transport, the equation of state, the physics of the opacity sources and the nuclear reactions. Attention is also given to the virial theorem, polytropic gas spheres and homology principles and the procedure for numerical solution of the equations is outlined. This book tracks the evolution of stars from their main-sequence evolution through the exhaustion of various nuclear fuels to the end points of evolution and also introduces the topic of interacting binary stars. The aim is to take the reader from the essential underlying physical principles to the doors to current research on stellar interiors.

This book shows that astronomical discovery is a complex and ongoing process comprising various stages of research, interpretation and understanding.

One of Canada's leading physicists celebrates the many, groundbreaking women scientists who came before her—unsung explorers of the cosmos who both discovered the fundamental rules of the universe and challenged social rules, yet whose names remain largely unknown to us. Her Space, Her Time shares the stories of women in physics and astronomy whose work expanded scientific understanding yet whose accomplishments are often overlooked—creating a thrilling account of scientific discovery, inspirational leadership and persistence in the face of overwhelming challenges. In shaping her narrative around the science that fascinated them and the social context in which they worked, award-winning quantum physicist Shohini Ghose champions these remarkable women’s contributions, which loom even larger given the misogyny and discrimination they faced. Ghose's canvas stretches from the 19th century to the present and includes many women whose work led to Nobel Prizes that were ultimately awarded to men. Among this list of impressive scientists: Henrietta Leavitt and Margaret Burbidge, who helped discover the big bang and the cosmic calendar; Anigaduwagi (Cherokee) aerospace scientist Mary Golda Ross, who helped make the Moon landings possible; atom splitter Lise Meitner; Bibha Chowdhuri, who discovered two fundamental particles; and Harriet Brooks—a Canadian physicist whose impact on radioactivity research was compared to Marie Curie’s, but who felt that marriage, not science, was the choice she had to make. Engaging and inspirational, Her Space, Her Time is threaded through with Ghose's own experiences in science—women in STEM still face the same kind of challenges her subjects encountered—and driven by the imperative to make the invisible visible, ensuring that the names of these women who pursued science against all odds will never be forgotten.

The years 2012/2013 mark the 50th anniversary of the theoretical prediction that Brown Dwarfs, i.e. degenerate objects which are just not massive enough to sustain stable hydrogen fusion, exist. Some 20 years after their discovery, how Brown Dwarfs form is still one of the main open questions in the theory of star formation. In this volume, the pioneers of Brown Dwarf research review the history of the theoretical prediction and the subsequent discovery of Brown Dwarfs. After an introduction, written by Viki Joergens, reviewing Shiv Kumar's theoretical prediction of the existence of brown dwarfs, Takenori Nakano reviews his and Hayashi's calculation of the Hydrogen Burning Minimum Mass. Both predictions happened in the early 1960s. Jill Tarter then writes on the introduction of the term 'Brown Dwarf', before Ben Oppenheimer, Rafael Rebolo and Gibor Basri describe their first discovery of Brown Dwarfs in the 1990s. Lastly, Michael Cushing and Isabelle Baraffe describe the development of the field to the current state of the art. While the book is mainly aimed at the Brown Dwarf research community, the description of the pioneering period in a scientific field will attract general readers interested in astronomy as well.

An in-depth look into the transformation of visual culture and digital aesthetics First introduced by the German filmmaker Harun Farocki, the term operational images defines the expanding field of machine vision. In this study, media theorist Jussi Parikka develops Farocki’s initial concept by considering the extent to which operational images have pervaded today’s visual culture, outlining how data technologies continue to develop and disrupt our understanding of images beyond representation. Charting the ways that operational images have been employed throughout a variety of fields and historical epochs, Parikka details their many roles as technologies of analysis, capture, measurement, diagramming, laboring, (machine) learning, identification, tracking, and destruction. He demonstrates how, though inextricable from issues of power and control, operational images extend their reach far beyond militaristic and colonial violence and into the realms of artificial intelligence, data, and numerous aspects of art, media, and everyday visual culture. Serving as an extensive guide to a key concept in contemporary art, design, and media theory, Operational Images explores the implications of machine vision and the limits of human agency. Through a wealth of case studies highlighting the areas where imagery and data intersect, this book gives us unprecedented insight into the ever-evolving world of posthuman visuality.

Women of Science is a collection of essays dealing with contributions women have made to various scientific disciplines, written by women scientists in those disciplines. The areas covered are: astronomy, archaeology, biology, chemistry, crystallography, engineering, geology, mathematics, medicine, and physics. The women who have written these essays are, for the most part, not professional historians, but rather scientific professionals who felt the necessity of researching the contributions women have made to the devlopment of their fields. The essays are unique, not only because they recover lost women who made significant contributions to their disciplines, but also because they are written with a depth of understanding that only a scientist working in a specific area can have. The essays will be of interest not only to students (especially women students) of science who may be unaware of the many contributions women have made, but also to readers of the history of science whoses texts more often than not fail to include the work of most women scientists.
