Book Description
Lunar explorations have received increasing attention in recent years with tremendous application values, including using the Moon as a remote sensing platform for Earth observation. As an active sensor, the Synthetic Aperture Radar (SAR) can detect changes in the atmosphere, terrain, and ocean. Moon-based SAR, complementary to the spaceborne SAR systems, expands our capabilities of watching and understanding the Earth. This book explains the Moon-Earth observation geometry, generic parameters, image focusing, and outlook using the Moon-based SAR. Written as a SAR imaging of Earth on the lunar-based platform, it makes it an essential reference to those interested in planetary and Earth sciences. FEATURES Uses the Moon as a remote sensing platform for Earth observation Explains how to obtain a high spatial resolution with a short revisit time using the Moon-based SAR Covers the observation geometry, range and signal models, two-dimensional signal spectrum, and focusing algorithms for the Moon-based SAR Presents a detailed analysis of sources of phase errors in the Moon-based SAR signal Includes global case studies and introduces conceptual ideas for further research This book is intended for senior graduate students, professional researchers, and engineers studying and working in the fields of lunar exploration and remote sensing applications, especially when dealing with high-orbit SAR studies.

Book Description
This volume presents recent work on Babylonian celestialdivination and on the Greek inheritors of the Babyloniantradition.In the ancient world, the collection and study of celestial phenomena and the intepretation of their prophetic significance, especially as applied to kings and nations, were closely related sciences carried out by the same scholars. Both ancient sources and modern research agree that astronomy and celestial divination arose in Babylon. Only in the late nineteenth century, however, did scholars begin to identify and decipher the original Babylonian sources, and the process of understanding those sources has been long and difficult. This volume presents recent work on Babylonian celestial divination and on the Greek inheritors of the Babylonian tradition. Both philological and mathematical work are included. The essays shed new light on all of the known textual sources, including the omen series Enuma Anu Enlil, which contains omens from as far back as the early second or even third millennium, and the earliest personal horoscopes, from about 400 B.C., as well as the Astronomical Diaries, ephemerides, and other observational and mathematical texts. One essay concerns astronomical papyri that confirm the extensive transmission of Babylonian methods into Greek; a study of Ptolemy's lunar theory suggests that Ptolemy relied more on his own observations than previously thought; and an analysis of Theon's commentary on Ptolemy's Handy Tables shows that Theon explicated their meaning both conscientiously and competently.ContributorsAsger Aaboe, Alan C.

Book Description
The first book to group together and analyze all the chronology construction methods used in different disciplines, this book will appeal to a wide range of researchers, scientists and graduate students using chronologies in their work; from applied statisticians to archaeologists, geologists and paleontologists, to those working in bioinformatics and chronometry. It is truly interdisciplinary and designed to enable cross fertilization of techniques.

Book Description
Chaos theory deals with the description of motion (in a general sense) which cannot be predicted in the long term although produced by deterministic system, as well exemplified by meteorological phenomena. It directly comes from the Lunar theory — a three-body problem — and the difficulty encountered by astronomers to accurately predict the long-term evolution of the Moon using “Newtonian” mechanics. Henri Poincaré's deep intuitions were at the origin of chaos theory. They also led the meteorologist Edward Lorenz to draw the first chaotic attractor ever published. But the main idea consists of plotting a curve representative of the system evolution rather than finding an analytical solution as commonly done in classical mechanics. Such a novel approach allows the description of population interactions and the solar activity as well. Using the original sources, the book draws on the history of the concepts underlying chaos theory from the 17th century to the last decade, and by various examples, show how general is this theory in a wide range of applications: meteorology, chemistry, populations, astrophysics, biomedicine, etc.

Book Description
Of all the giants on whose shoulders we stand, Aristarchos of Samos, the ancient Greek all-rounder, has proved to be especially tall: no one else (not even Einstein, to mention an iconic figure) has ever discovered anything (of like importance) that took so long to dawn on the rest of humanity. His achievement was extraordinary: with nothing more than the naked eye and the mind of a genius, he got to know the Sun's distance better than anyone else before, and he put the Earth in motion around the Sun for the first time in human awareness. The present book examines what history has spared of him and invites the reader to relive astronomy's finest hour.
