Time - From Earth Rotation to Atomic Physics

• Gebundenes Buch

Produktbeschreibung

Filling the need for a book that conveys the current technology as well as the underlying history and physical background, this book tells physicists and engineers how to measure time to the precision required for modern-day use. The authors draw on their longstanding research experience with timekeeping and high-precision measurement to cover the use of satellites in measuring earth movement variation and the influence of the moon, while also dwelling on such topics as timekeeping aboard satellites and time transfer.
Indispensable for high-precision measurements of processes in astrophysics, and relevant for measurement, navigation and communication, this monograph can be equally used as a course book or as accompanying work at advanced undergraduate or graduate level.

Autorenporträt

P. Kenneth Seidelmann worked in the Nautical Almanac and Orbital Mechanics Departments of the U. S. Naval Observatory for 35 years, reaching the level of Director of Astrometry at USNO. He has been involved in the ephemerides developments, relativistic developments of dynamical time scales, and the applications of improved accuracies of time scales and astrometry. He is currently a Research Professor at the University of Virginia. He is editor of the 'Explanatory Supplement to the Astronomical Almanac', coauthor of 'Fundamentals of Astrometry', and author of a large number of papers on astronomy.

Dennis D. McCarthy worked in the Time Service and Earth Orientation Departments of the U. S. Naval Observatory (USNO) for the past 40 years, reaching the position of Director of Time at USNO. He has been involved in both the developments of time keeping and time transfer, and the developments of accurate Earth Orientation observation and prediction. He is the author of a large number of papers on time scales and Earth Orientation.
