Download and read online ebook Historical Eclipses and Earth's Rotation write by F. Richard Stephenson. This book was released on 1997-06-05. Historical Eclipses and Earth's Rotation available in PDF, EPUB and Kindle. This book is intended for geophysicists, astronomers (especially those with an interest in history), historians and orientalists. The culmination of many years of research, it discusses, in depth, ancient and medieval eclipse observations and their importance in studying Earth's past rotation. This was the first major book on this subject to appear in the last twenty years. The author has specialised in the interpretation of early astronomical records and their application to problems in modern astronomy for many years. The book contains an in-depth discussion of numerous eclipse records from Babylon, China, Europe and the Arab lands. Translations of almost every record studied are given. It is shown that although tides play a dominant long-term role in producing variations in Earth's rate of rotation - causing a gradual increase in the length of the day - there are significant, and variable non-tidal changes in opposition to the main trend.

This book was released on 2017-03-07. Mask of the Sun available in PDF, EPUB and Kindle. What do Emily Dickinson, slave revolts, Babylonian Kings, and Monticello all have in common? A solar eclipse. Whether it was deciding on the location of a grand home (or castle), inspiring poetry, timing battles and revolts, or planning expeditions, eclipses have inspired fear and fascination. Solar eclipses allowed Ptolemy to determine the length of the Mediterranean and helped Einstein establish his General Theory of Relativity. Preliterate societies recorded eclipses on turtle shells found in "The Wastes of Yin" and on the Mayan "Dresden Codex." Eclipses were later instrumental in the creation of longitude and allowed Hubble to understand the expansion of the Universe (and disprove another theory of Einstein's in the process). John Dvorak, the acclaimed author of Earthquake Storms and The Last Volcano, examines this amazing phenomena and reveals the humanism behind the science. With insightful detail and vividly accessible prose, he provides explanations as to how and why eclipses occur—as well as insight into the eclipse of 2017, which was visible across North America.

Download and read online ebook Time: From Earth Rotation to Atomic Physics write by Dennis D. McCarthy. This book was released on 2018-10-18. Time: From Earth Rotation to Atomic Physics available in PDF, EPUB and Kindle. 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.

Download and read online ebook Earth’s Rotation from Eons to Days write by Peter Brosche. This book was released on 2012-12-06. Earth’s Rotation from Eons to Days available in PDF, EPUB and Kindle. Earth's Rotation from Eons to Days reviews long-term changes, methods of measurement, and the major influences on rotation parameters. In order to understand secular changes, the momentary behavior of ocean tides must be analyzed and appropriately modelled. Researchers and students in astronomy and all fields of geosciences will find a wealth of information related to the interaction of geophysical phenomena and the rotation of the planet Earth.
