Download or read book An Introduction to Modern Timekeeping and Time Transfer written by Parameswar Banerjee and published by Springer. This book was released on 2023-08-31 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive, systematic description of modern timekeeping and its specializations. Introductory chapters discuss the concept of time and its definition, then briefly look at pre-Atomic Era timekeeping to set the stage for the introduction of the atomic clock. Subsequent chapters focus on concepts such as frequency stability and measurement uncertainty, as well as computer network time-synchronization protocols including Network Time Protocol (NTP) and Precise Time Protocol (PTP). The book then delves into the nuts and bolts of the Global Navigation Satellite Systems (GNSS), Two-Way Satellite Time and Frequency Transfer, and Optical Time and Frequency Transfer. Timescale theory is then described as a way to combine clock data, and the algorithms and procedures used to generate Coordinated Universal Time (UTC) are given. Finally, there is a look at modern applications of timekeeping and time transfer. Featuring a glossary of all key terms, this book is highly recommended for trained or incoming physicists, engineers, or mathematicians working, for example, in manufacturing or timing laboratories. Additionally, it is suitable for use in introductory university courses dealing with the subject of timekeeping.

Download or read book Time written by Dennis D. McCarthy and published by Wiley-VCH. This book was released on 2009-11-23 with total page 373 pages. Available in PDF, EPUB and Kindle. Book excerpt: Filling the need for a book that presents the current technology as well as the underlying historical and physical background, this publication informs scientists, engineers, and those interested in the foundations of modern timekeeping how precise time and frequency are made available for modern-day use. The authors draw on their longstanding research experience with timekeeping and high-precision measurements to describe the discovery of the irregular motions of the Earth, the development of mechanical and atomic clocks, the introduction of dynamical timescales, and the development of the study of the Earth's orientation in space. Also discussed are astronomical and satellite observations used to improve solar system dynamics and Earth kinematics along with the applications of the theory of relativity to the topics of timekeeping and time transfer. Indispensable for high-precision measurements and applications in astronomy, space sciences, and geodesy, and relevant for physical measurements, navigation, and communication, this monograph can be used equally as a course book or as accompanying work at advanced undergraduate, graduate, and professional levels.

Download or read book Brief History of Timekeeping written by Chad Orzel and published by Simon and Schuster. This book was released on 2022-02-03 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: ‘Entertaining and engrossing’ Sean Carroll Press the snooze button on your alarm once too often and you soon remember the importance of good timekeeping. That need to tell the time connects you to over five thousand years of human history, from the first solstice markers at Newgrange to quartz crystal oscillating in your watch today. Science underpins time: measuring the movement of Sun, Earth and Moon, and unlocking the mysteries of quantum mechanics and relativity theory – the key to ultra-precise atomic clocks. Yet time is also socially decided: the Gregorian calendar we use today came out of fraught politics, while the ancient Maya used sophisticated astronomical observations to produce a calendar system unlike any other. In his quirky and accessible style, Chad Orzel reveals the wondrous physics that makes time something we can set, measure and know.
