Book Synopsis Measuring the Cosmos by : David H. Clark
Download or read book Measuring the Cosmos written by David H. Clark and published by Rutgers University Press. This book was released on 2004 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 excerpt: 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 Synopsis Measuring the Universe by : Kitty Ferguson
Download or read book Measuring the Universe written by Kitty Ferguson and published by Random House. This book was released on 2013-01-31 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 Synopsis Measuring the Universe by : George H. Rieke
Download or read book Measuring the Universe written by George H. Rieke and published by Cambridge University Press. This book was released on 2017-05-25 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Roman Ondák written by Roman Ondák and published by Jrp Ringier. This book was released on 2008 with total page 182 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Book Synopsis Miss Leavitt's Stars by : George Johnson
Download or read book Miss Leavitt's Stars written by George Johnson and published by WW Norton. This book was released on 2006-05-30 with total page 179 pages. Available in PDF, EPUB and Kindle. Book excerpt: "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.

Download or read book Magnitude written by Megan Watzke and published by Black Dog & Leventhal. This book was released on 2017-11-21 with total page 233 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the tradition of illustrated science bestsellers, like Thing Explainer andharkening back to the classic film The Powers of Ten, this unique, fully-illustrated, four-color book explores and visualizes the concept of scale in our universe. In Magnitude, Kimberly Arcand and Megan Watzke take us on an expansive journey to the limits of size, mass, distance, time, temperature in our universe, from the tiniest particle within the structure of an atom to the most massive galaxy in the universe; from the speed at which grass grows (about 2 to 6 inches a month) to the speed of light. Fully-illustrated with four-color drawings and infographics throughout and organized into sections including Size and Amount (Distance, Area, Volume, Mass, Time, Temperature), Motion and Rate (Speed, Acceleration, Density, Rotation), and Phenomena and Processes (Energy, Pressure, Sound, Wind, Computation), Magnitude shows us the scale of our world in a clear, visual way that our relatively medium-sized human brains can easily understand.
Book Synopsis The Extravagant Universe by : Robert P. Kirshner
Download or read book The Extravagant Universe written by Robert P. Kirshner and published by Princeton University Press. This book was released on 2016-09-13 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Extravagant Universe tells the story of a remarkable adventure of scientific discovery. One of the world's leading astronomers, Robert Kirshner, takes readers inside a lively research team on the quest that led them to an extraordinary cosmological discovery: the expansion of the universe is accelerating under the influence of a dark energy that makes space itself expand. In addition to sharing the story of this exciting discovery, Kirshner also brings the science up-to-date in a new epilogue. He explains how the idea of an accelerating universe--once a daring interpretation of sketchy data--is now the standard assumption in cosmology today. This measurement of dark energy--a quality of space itself that causes cosmic acceleration--points to a gaping hole in our understanding of fundamental physics. In 1917, Einstein proposed the "cosmological constant" to explain a static universe. When observations proved that the universe was expanding, he cast this early form of dark energy aside. But recent observations described first-hand in this book show that the cosmological constant--or something just like it--dominates the universe's mass and energy budget and determines its fate and shape. Warned by Einstein's blunder, and contradicted by the initial results of a competing research team, Kirshner and his colleagues were reluctant to accept their own result. But, convinced by evidence built on their hard-earned understanding of exploding stars, they announced their conclusion that the universe is accelerating in February 1998. Other lines of inquiry and parallel supernova research now support a new synthesis of a cosmos dominated by dark energy but also containing several forms of dark matter. We live in an extravagant universe with a surprising number of essential ingredients: the real universe we measure is not the simplest one we could imagine.
Book Synopsis The Most Interesting Galaxies in the Universe by : Joel L Schiff
Download or read book The Most Interesting Galaxies in the Universe written by Joel L Schiff and published by Morgan & Claypool Publishers. This book was released on 2018-09-13 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: Prior to the 1920s it was generally thought, with a few exceptions, that our galaxy, the Milky Way, was the entire Universe. Based on the work of Henrietta Leavitt with Cepheid variables, astronomer Edwin Hubble was able to determine that the Andromeda Galaxy and others had to lie outside our own. Moreover, based on the work of Vesto Slipher, involving the redshifts of these galaxies, Hubble was able to determine that the Universe was not static, as had been previously thought, but expanding. The number of galaxies has also been expanding, with estimates varying from 100 billion to 2 trillion. While every galaxy in the Universe is interesting just by its very fact of being, the author has selected 51 of those that possess some unusual qualities that make them of some particular interest. These galaxies have complex evolutionary histories, with some having supermassive black holes at their core, others are powerful radio sources, a very few are relatively nearby and even visible to the naked eye, whereas the light from one recent discovery has been travelling for the past 13.4 billion years to show us its infancy, and from a time when the Universe was in its infancy. And in spite of the vastness of the Universe, some galaxies are colliding with others, embraced in a graceful gravitational dance. Indeed, as the Andromeda Galaxy is heading towards us, a similar fate awaits our Milky Way. When looking at a modern image of a galaxy, one is in awe at the shear wondrous nature of such a magnificent creation, with its boundless secrets that it is keeping from us, its endless possibilities for harboring alien civilizations, and we remain left with the ultimate knowledge that we are connected to its glory.
Download or read book Our Universe written by Jo Dunkley and published by Belknap Press. This book was released on 2019-04-08 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Book Synopsis The Universe as It Really Is by : Thomas R. Scott
Download or read book The Universe as It Really Is written by Thomas R. Scott and published by Columbia University Press. This book was released on 2018-06-26 with total page 511 pages. Available in PDF, EPUB and Kindle. Book excerpt: The universe that science reveals to us can seem far outside the comfort zone of the human mind. Subjects near and far open up dizzying vistas, from the infinitesimal to the colossal. Humanity, the unlikely product of uncountable coincidences on unimaginable scales, inhabits a tumultuous universe that extends from our immediate environs to the most distant galaxies and beyond. But when the mind balks at the vertiginous complexity of the universe, science unveils the elegance amid the chaos. In this book, Thomas R. Scott ventures into the known and the unknown to explain our universe and the laws that govern it. The Universe as It Really Is begins with physics and the building blocks of the universe—time, gravity, light, and elementary particles—and chemistry’s ability to explain the interactions among them. Scott, with the assistance of James Lawrence Powell, next tours the earth and atmospheric sciences to explain the forces that shape our planet and then takes off for the stars to describe our place in the cosmos. He provides vivid introductions to our collective scientific inheritance, narrating discoveries such as the shape of the atom and the nature of the nucleus or how we use GPS to measure time and what that has to do with relativity. A clear demonstration of the power of scientific reasoning to bring the incomprehensible within our grasp, The Universe as It Really Is gives an engrossing account of just how much we do understand about the world around us.
Book Synopsis Finding Our Place in the Universe by : Helene Courtois
Download or read book Finding Our Place in the Universe written by Helene Courtois and published by MIT Press. This book was released on 2019-05-28 with total page 181 pages. Available in PDF, EPUB and Kindle. Book excerpt: An astrophysicist recounts how her team of researchers surfed the cosmos to map our local universe—and discovered the Laniakea supercluster, home of the Milky Way. You are here: on Earth, which is part of the solar system, which is in the Milky Way galaxy, which itself is within the extragalactic supercluster Laniakea. And how can we pinpoint our location so precisely? For 20 years, astrophysicist Hélène Courtois surfed the cosmos with international teams of researchers, working to map our local universe. In this book, Courtois describes this quest and the discovery of our home supercluster. Courtois explains that Laniakea (which means “immense heaven” in Hawaiian) is the largest galaxy structure known to which we belong; it is huge, almost too large to comprehend—about 500 million light-years in diameter. It contains about 100,000 large galaxies like our own, and a million smaller ones. Writing accessibly for nonspecialists, Courtois describes the visualization and analysis that allowed her team to map such large structures of the universe. She highlights the work of individual researchers, including portraits of several exceptional women astrophysicists—presenting another side of astronomy. Key ideas are highlighted in text insets; illustrations accompany the main text. The French edition of this book was named the Best Astronomy Book of 2017 by the astronomy magazine Ciel et espace. For this MIT Press English-language edition, Courtois has added descriptions of discoveries made after Laniakea: the cosmic velocity web and the Dipole and Cold Spot repellers. An engaging account of one of the most important discoveries in astrophysics in recent years, her story is a tribute to teamwork and international collaboration.
