Available in PDF, EPUB and Kindle. Book excerpt: This book illuminates a few highly significant events in history in which astronomers have helped keep contacts between astronomers of different states in moments of international political tensions or even crises. The chapters, written by 20 international authors, focus on four periods where astronomers were particularly active in international relations: 1. The WWI period, the epoch of the creation of the IAU, in the context of the simultaneous creation of other scientific unions. The book also singles out the important role of A.S. Eddington and his network “across forbidden borders”. 2. The Cold war period and its consequences, when several countries were divided between opposite blocs. “The China crisis” is told here from different viewpoints by Chinese astronomers, both from the mainland and from Taiwan, in parallel with the evolution of astronomy in South and North Korea. Germany’s twisted path in its membership of the IAU, from its admission in 1951 to its reunification in 1991 is shown as another example. 3. The book then highlights a third period, when radio astronomers, in particular, were very active in “building bridges” between East and West. It also tells the history of how the apparently innocuous issue of the “lunar nomenclature” became extremely sensitive. The part ends on two chapters on Russian robotic missions and lunar surface features as well on the Russian participation in the “International Virtual Observatory” project. 4. The fourth part reports for the first time on the “hidden story” of the relations between the IAU and the United Nations after the “Moon race” when the United Nations decided to challenge the IAU’s authority on “extraterrestrial names”. The final chapter reviews how twenty years later UNESCO and the IAU had become strong partners in the difficult, but highly successful organization of the International Year of Astronomy (2002-2009), and of the “Astronomy and World Heritage” intitiative (2008).

Download or read book Relativistic Celestial Mechanics of the Solar System written by Sergei Kopeikin and published by John Wiley & Sons. This book was released on 2011-10-25 with total page 897 pages. Available in PDF, EPUB and Kindle. Book excerpt: This authoritative book presents the theoretical development of gravitational physics as it applies to the dynamics of celestial bodies and the analysis of precise astronomical observations. In so doing, it fills the need for a textbook that teaches modern dynamical astronomy with a strong emphasis on the relativistic aspects of the subject produced by the curved geometry of four-dimensional spacetime. The first three chapters review the fundamental principles of celestial mechanics and of special and general relativity. This background material forms the basis for understanding relativistic reference frames, the celestial mechanics of N-body systems, and high-precision astrometry, navigation, and geodesy, which are then treated in the following five chapters. The final chapter provides an overview of the new field of applied relativity, based on recent recommendations from the International Astronomical Union. The book is suitable for teaching advanced undergraduate honors programs and graduate courses, while equally serving as a reference for professional research scientists working in relativity and dynamical astronomy. The authors bring their extensive theoretical and practical experience to the subject. Sergei Kopeikin is a professor at the University of Missouri, while Michael Efroimsky and George Kaplan work at the United States Naval Observatory, one of the world?s premier institutions for expertise in astrometry, celestial mechanics, and timekeeping.

Download or read book The Science of Time 2016 written by Elisa Felicitas Arias and published by Springer. This book was released on 2017-10-05 with total page 381 pages. Available in PDF, EPUB and Kindle. Book excerpt: The uses of time in astronomy - from pointing telescopes, coordinating and processing observations, predicting ephemerides, cultures, religious practices, history, businesses, determining Earth orientation, analyzing time-series data and in many other ways - represent a broad sample of how time is used throughout human society and in space. Time and its reciprocal, frequency, is the most accurately measurable quantity and often an important path to the frontiers of science. But the future of timekeeping is changing with the development of optical frequency standards and the resulting challenges of distributing time at ever higher precision, with the possibility of timescales based on pulsars, and with the inclusion of higher-order relativistic effects. The definition of the second will likely be changed before the end of this decade, and its realization will increase in accuracy; the definition of the day is no longer obvious. The variability of the Earth's rotation presents challenges of understanding and prediction. In this symposium speakers took a closer look at time in astronomy, other sciences, cultures, and business as a defining element of modern civilization. The symposium aimed to set the stage for future timekeeping standards, infrastructure, and engineering best practices for astronomers and the broader society. At the same time the program was cognizant of the rich history from Harrison's chronometer to today's atomic clocks and pulsar observations. The theoreticians and engineers of time were brought together with the educators and historians of science, enriching the understanding of time among both experts and the public.
Download or read book The International Astronomical Union written by Johannes Andersen and published by Springer. This book was released on 2019-02-20 with total page 383 pages. Available in PDF, EPUB and Kindle. Book excerpt: The International Astronomical Union (IAU) was founded in 1919, in the wake of the First World War, together with its sister Unions in related natural sciences. It will thus turn 100 years in 2019. Written by a mixed team of insiders and outsiders, this book presents the IAU in the changing context of the historical, scientific and technological development of astronomy during the past 100 years. While much important scientific progress took place already before 1945, the book naturally focuses on the accelerating evolution during the second half of the century. In the past few decades, the previously narrow IAU focus on organising professional astronomy has broadened to include societally relevant activities such as addressing the hazard of asteroid impacts, the planetary status of Pluto in the Solar System, and the hugely successful International Year of Astronomy. Most recently, it is spearheading a combination of science literacy and public outreach. The book will be of interest to professional astronomers as well as an astronomically interested general audience. The book features live personal interviews with as many of the key actors as still possible.
Download or read book History of the IAU written by Adriaan Blaauw and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: This History has its origin in a suggestion, made in September 1990 by former IAU General Secretary Derek McNally, who felt "that a 75 year history of the Union was needed before the col lective memory of those who knew the Union before the Second World War vanished. It would then be a preparatory volume to a centennial history in 2019. " Indeed, of those who knew the Union that long ago, few are still with us. Six years ago, at Baltimore on August 2, 1988, listening and reminiscing at the Inaugural Ceremonies of the Union's 20th General Assembly, I realized that it was almost exactly half a century ago that, at the age of 24, I attended the Inaugurations at my "first" Assembly: on August 3, 1938 in Stockholm. Now, in 1994, this is almost 56 years ago, three quarters of the Union's age. Only vague recollections - no better than that -lead me back to this event, just before World War II. And so, this is not a history based on recollection, far from it. Recollection was helpful in that it allowed me, better perhaps than a younger author, to appreciate circumstances under which the letters and reports which form the basis for this History were written. The account is largely based on archival documents, collected from a wide variety of sources.
