This artful social history considers our culture's expectations of women and how those expectations changed throughout the twentieth century, how the advent of television changed the landscape of employment opportunities for women in broadcasting, and how both television and radio communicate about gender roles.
From the discovery of entirely new kinds of galaxies to a window into cosmic ‘prehistory’, Bothwell shows us the Universe as we’ve never seen it before – literally. Since the dawn of our species, people all over the world have gazed in awe at the night sky. But for all the beauty and wonder of the stars, when we look with just our eyes we are seeing and appreciating only a tiny fraction of the Universe. What does the cosmos have in store for us beyond the phenomena we can see, from black holes to supernovas? How different does the invisible Universe look from the home we thought we knew? Dr Matt Bothwell takes us on a journey through the full spectrum of light and beyond, revealing what we have learned about the mysteries of the Universe. This book is a guide to the ninety-nine per cent of cosmic reality we can’t see – the Universe that is hidden, right in front of our eyes. It is also the endpoint of a scientific detective story thousands of years in the telling. It is a tour through our Invisible Universe.
Invisible Stars was the first book to recognize that women have always played an important part in American electronic media. The emphasis is on social history, as the author skillfully explains how the changing role of women in different eras influenced their participation in broadcasting. This is not just the story of radio stars or broadcast journalists, but a social history of women both on and off the air. Beginning in the early 1920s with the emergence of radio, the book chronicles the ambivalence toward women in broadcasting during the 1930s and 1940s, the gradual change in status of women in the 1950s and 1960s, the increased presence of women in broadcasting in the 1970s, and the successes of women in broadcasting in the 1980s and 1990s. The second edition is expanded to include the social and political changes that occurred in the 2000s, such as the growing number of women talk show hosts; changing attitudes about women in leadership roles in business; more about minority women in media; and women in sports and women sports announcers. The author addresses the question of whether women are in fact no longer invisible in electronic media. She provides an assessment of where progress for women (in society as well as broadcasting) can be seen, and where progress appears totally stalled.
Geronimo discovers a planet on the radar that mysteriously appears and disappears. MouseStar 1 lands to investigate and they discover mysterious aliens who hide a secret!
This publication, "Making the Invisible Visible: A History of the Spitzer Infrared Telescope Facility (1971-2003)," makes visible the invisible forces that influenced the design of Space Infrared Telescope Facility (SIRTF's) innovative technology. The lessons learned by the project team over the course of building SIRTF, now better known as the Spitzer Space Telescope, are about managing innovation over time and in the face of uncertainty. These are universal lessons, applicable to any project whose stakeholders control the necessary resources. SIRTF's stakeholders focused on a variety of issues: technical, scientific, political, and economic, as well as organizational needs and goals. What made SIRTF's evolution particularly difficult was that the stakeholders changed over time-in their composition, goals, and influence.
ROSAT, the ROentgen SATellite launched in 1990, has revealed an entirely new aspect of the night sky - that of objects emitting X-rays rather than the rays of light visible to the human eye. This lavishly illustrated book is the first to describe one of the most remarkable instruments in modern astronomy. It offers fascinating images and engaging accounts of a wide range of Solar-System and deep space objects such as Comet Hyakutake, the Sun, the Moon, and objects outside the Milky Way.
'Why'? Why is the world, the Universe the way it is? Is space infinitely large? How small is small? What happens when one continues to divide matter into ever smaller pieces? Indeed, what is matter? Is there anything else besides what can be seen? Pursuing the questions employing the leading notions of physics, one soon finds that the tangible and visible world dissolves — rather unexpectedly — into invisible things and domains that are beyond direct perception. A remarkable feature of our Universe is that most of its constituents turn out to be invisible, and this fact is brought out with great force by this book.Exploring the Invisible Universe covers the gamut of topics in advanced modern physics and provides extensive and well substantiated answers to these questions and many more. Discussed in a non-technical, yet also non-trivial manner, are topics dominated by invisible things — such as Black Holes and Superstrings as well as Fields, Gravitation, the Standard Model, Cosmology, Relativity, the Origin of Elements, Stars and Planetary Evolution, and more. Just giving the answer, as so many books do, is really not telling anything at all. To truly answer the 'why' questions of nature, one needs to follow the chain of reasoning that scientists have used to come to the conclusions they have. This book does not shy away from difficult-to-explain topics by reducing them to one-line answers and power phrases suitable for a popular talk show. The explanations are rigorous and straight to the point. This book is rarely mathematical without being afraid, however, to use elementary mathematics when called for. In order to achieve this, a large number of detailed figures, specially developed for this book and found nowhere else, convey insights that otherwise might either be inaccessible or need lengthy and difficult-to-follow explanations.After Exploring the Invisible Universe, a reader will have a deeper insight into our current understanding of the foundations of Nature and be able to answer all the questions above and then some. To understand Nature and the cutting edge ideas of contemporary physics, this is the book to have.
