Book Synopsis Time: From Earth Rotation to Atomic Physics by : Dennis D. McCarthy
Download or read book Time: From Earth Rotation to Atomic Physics written by Dennis D. McCarthy and published by Cambridge University Press. This book was released on 2018-10-18 with total page 403 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the twenty-first century, we take the means to measure time for granted, without contemplating the sophisticated concepts on which our time scales are based. This volume presents the evolution of concepts of time and methods of time keeping up to the present day. It outlines the progression of time based on sundials, water clocks, and the Earth's rotation, to time measurement using pendulum clocks, quartz crystal clocks, and atomic frequency standards. Time scales created as a result of these improvements in technology and the development of general and special relativity are explained. This second edition has been updated throughout to describe twentieth- and twenty-first-century advances and discusses the redefinition of SI units and the future of UTC. A new chapter on time and cosmology has been added. This broad-ranging reference benefits a diverse readership, including historians, scientists, engineers, educators, and it is accessible to general readers.

Book Synopsis Sky and Ocean Joined by : Steven J. Dick
Download or read book Sky and Ocean Joined written by Steven J. Dick and published by Cambridge University Press. This book was released on 2003 with total page 636 pages. Available in PDF, EPUB and Kindle. Book excerpt: As one of the oldest scientific institutions in the United States, the US Naval Observatory has a rich and colourful history. This volume is, first and foremost, a story of the relations between space, time and navigation, from the rise of the chronometer in the United States to the Global Positioning System of satellites, for which the Naval Observatory provides the time to a billionth of a second per day. It is a story of the history of technology, in the form of telescopes, lenses, detectors, calculators, clocks and computers over 170 years. It describes how one scientific institution under government and military patronage has contributed, through all the vagaries of history, to almost two centuries of unparalleled progress in astronomy. Sky and Ocean Joined will appeal to historians of science, technology, scientific institutions and American science, as well as astronomers, meteorologists and physicists.
Book Synopsis Highlights of Astronomy by : G. Contopoulos
Download or read book Highlights of Astronomy written by G. Contopoulos and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 543 pages. Available in PDF, EPUB and Kindle. Book excerpt: The year 1973 marked the highest peak of IAU activity up to now. Besides the Gen eral Assembly in Sydney, and the Extraordinary General Assembly in Poland, there were held eleven IAU Symposia and one Colloquium. Several IAU Publications cover this activity. The Proceedings of the Symposia are published in separate Volumes, while the Transactions of the General Assembly and of the Extraordinary General Assembly contain short reports of the Commission meetings, the administrative sessions, and the opening ceremonies. The present Volume covers some of the scientific Highlights of the General As sembly and of the Extraordinary General Assembly. It contains five Invited Dis courses given in Sydney and Poland, some selected papers, and the Joint Discussions at the General Assembly of Sydney. Of course, there were many more papers of special interest presented in Sydney that could not be included in this Volume. Their titles can be seen in the reports of the various Commissions. It is regrettable that the Invited Discourses of C. H. Townes (Interstellar Molecules) and F. J. Low (Infrared Astronomy) were not submitted for publication. Also only five papers or abstracts of the Joint Discussion on the 'Origins of the Moon and Satellites' have been available. Despite these minor shortcomings, I believe that the present Volume is faithful to its title: it gives a substantial part of the Highlights of Astronomy in 1973.

Book Synopsis Metrology at the Frontiers of Physics and Technology by : L. Crovini
Download or read book Metrology at the Frontiers of Physics and Technology written by L. Crovini and published by Elsevier. This book was released on 1992-10-22 with total page 673 pages. Available in PDF, EPUB and Kindle. Book excerpt: The spectroscopy of trapped ions or laser-cooled atoms offers the prospect of visible frequency standards to match or even exceed the accuracy of the caesium standard. The development of satellite methods for time comparisons has improved by more than an order of magnitude the accuracy with which national laboratories can routinely compare their clocks. Mechanical metrology has not been left behind. Driven by the need to improve manufacturing technology, major advances have taken place in computer control machining and mechanical measuring systems. These, and many other fascinating developments in the field of metrology are presented in this book.
