Book Description
Award-winners Mary and John Gribbin unravel the history of modern astronomy. How far is it to the edge of the Universe? It is less than eighty years since astronomers began to realise that even the distances to the stars are tiny steps on a truly cosmic scale, and that the Milky Way Galaxy in which we live is just one island in an immense ocean of space. John and Mary Gribbin tell the story of how the cosmic distance scale was measured, the personalities involved and the increasingly sophisticated instruments they used. Astronomers can now study light from objects so distant that it has taken ten billion years on its journey across space to us, travelling all the time at a speed of 300,000 kilometres per second: that's how far up is!

Book Description
Astronomy is an observational science, renewed and even revolutionized by new developments in instrumentation. With the resulting growth of multiwavelength investigation as an engine of discovery, it is increasingly important for astronomers to understand the underlying physical principles and operational characteristics for a broad range of instruments. This comprehensive text is ideal for graduate students, active researchers and instrument developers. It is a thorough review of how astronomers obtain their data, covering current approaches to astronomical measurements from radio to gamma rays. The focus is on current technology rather than the history of the field, allowing each topic to be discussed in depth. Areas covered include telescopes, detectors, photometry, spectroscopy, adaptive optics and high-contrast imaging, millimeter-wave and radio receivers, radio and optical/infrared interferometry, and X-ray and gamma-ray astronomy, all at a level that bridges the gap between the basic principles of optics and the subject's abundant specialist literature. Color versions of figures and solutions to selected problems are available online at www.cambridge.org/9780521762298.

Book Description
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.

Book Description
Suppose you and I still wondered whether all of the pinpoints of light in the night sky are the same distance from us. Suppose none of our contemporaries could tell us whether the Sun orbits the Earth, or vice versa, or even how large the Earth is. Suppose no one had guessed there are mathematical laws underlying the motions of the heavens. How would - how did - anyone begin to discover these numbers and these relationships without leaving the Earth? What made anyone even think it was possible to find out “how far,” without going there? In Measuring the Universe we join our ancestors and contemporary scientists as they tease this information out of a sky full of stars. Some of the questions have turned out to be loaded, and a great deal besides mathematics and astronomy has gone into answering them. Politics, religion, philosophy and personal ambition: all have played roles in this drama. There are poignant personal stories, of people like Copernicus, Kepler, Newton, Herschel, and Hubble. Today scientists are attempting to determine the distance to objects near the borders of the observable universe, far beyond anything that can be seen with the naked eye in the night sky, and to measure time back to its origin. The numbers are too enormous to comprehend. Nevertheless, generations of curious people have figured them out, one resourceful step at a time. Progress has owed as much to raw ingenuity as to technology, and frontier inventiveness is still not out of date.

Book Description
Humans have always viewed the heavens with wonder and awe. The skies have inspired reflection on the vastness of space, the wonder of creation, and humankind's role in the universe. In just over one hundred years, science has moved from almost total ignorance about the actual distances to the stars and earth's place in the galaxy to our present knowledge about the enormous size, mass, and age of the universe. We are reaching the limits of observation, and therefore the limits of human understanding. Beyond lies only our imagination, seeded by the theories of physics. In Measuring the Cosmos, science writers David and Matthew Clark tell the stories of both the well-known and the unsung heroes who played key roles in these discoveries. These true accounts reveal ambitions, conflicts, failures, as well as successes, as the astonishing scale and age of the universe were finally established. Few areas of scientific research have witnessed such drama in the form of ego clashes, priority claims, or failed (or even falsified) theories as that resulting from attempts to measure the universe. Besides giving credit where long overdue, Measuring the Cosmos explains the science behind these achievements in accessible language sure to appeal to astronomers, science buffs, and historians.

Book Description
Roman Ondák represents the Slovak Republic at the 2009 Venice Biennale. In this volume the Slovak artist Roman Ondák has brought together some of his works that deal with time, measurement, and surveying along with those that make visible what evades the visual, namely boundaries and experience. Alongside a complete documentation of the exhibition Measuring the Universe, where the museum attendants checked the body size of the visitors throughout its duration, one also finds Failed Fall (2008), a greenhouse's floor filled with dried autumn leaves, and Across that Place (2008), the story of the no longer existing Canal Zone by the Panama Canal. Whether working with installation, photography, drawing, or performance, Ondák underpins his work with processes, embedding them into the course of an action. The action extends over time, transcribes a scenario rather than explaining it, and can be attached to radically minimalist objects, or as in this case, to extremely narrative books. Anything that plays a role in his work has its place in this book: the displacement of people and places, presence and absence, the economy of time. This publication is part of the series of artists' projects by Christoph Keller Editions in collaboration with BAWAG Foundation. English text.

A BBC Sky at Night Best Astronomy and Space Book of the Year “[A] luminous guide to the cosmos...Jo Dunkley swoops from Earth to the observable limits, then explores stellar life cycles, dark matter, cosmic evolution and the soup-to-nuts history of the Universe.” —Nature “A grand tour of space and time, from our nearest planetary neighbors to the edge of the observable Universe...If you feel like refreshing your background knowledge...this little gem certainly won’t disappoint.” —Govert Schilling, BBC Sky at Night Most of us have heard of black holes and supernovas, galaxies and the Big Bang. But few understand more than the bare facts about the universe we call home. What is really out there? How did it all begin? Where are we going? Jo Dunkley begins in Earth’s neighborhood, explaining the nature of the Solar System, the stars in our night sky, and the Milky Way. She traces the evolution of the universe from the Big Bang fourteen billion years ago, past the birth of the Sun and our planets, to today and beyond. She then explains cutting-edge debates about such perplexing phenomena as the accelerating expansion of the universe and the possibility that our universe is only one of many. Our Universe conveys with authority and grace the thrill of scientific discovery and a contagious enthusiasm for the endless wonders of space-time.

"A short, excellent account of [Leavitt’s] extraordinary life and achievements." —Simon Singh, New York Times Book Review George Johnson brings to life Henrietta Swan Leavitt, who found the key to the vastness of the universe—in the form of a “yardstick” suitable for measuring it. Unknown in our day, Leavitt was no more recognized in her own: despite her enormous achievement, she was employed by the Harvard Observatory as a mere number-cruncher, at a wage not dissimilar from that of workers in the nearby textile mills. Miss Leavitt’s Stars uncovers her neglected history.
