Scientific Observation of Harmonic Drift in Lunar Dates Against Gregorian Calendar


Book Description

Astronomy is one of earliest sciences that continued to evolve, through its application particularly in monitoring its evolving time. This has been proven as powerful tool in pegging important events in the evolution of human civilization. One of such phenomena is the lunar movement and it's implicating on lunar calendar, a template used by many countries around the world, notably Chinese, Jews and Muslim calendar. Observation shows that, dates in Islamic calendar, which are based on counting of days after first sighting of new crescent moon, at about 30 minutes after sunset, are mostly controversial. Considering the present advancement in science and technology, the controversy still persists and there is no available lunar calendar that is reliable for accurate longtime planning for Islamic activities. This resulted to lack of convincing Islamic calendar.Generally, observation that depends on naked eye sighting which has been widely used locally, cannot give reliable data for scientific analysis of lunar calendar because, the new crescent moon could be above western horizon after sunset, but due to obscurity impinged by weather or visual impairment, it may not be sighted. Therefore, for a true evaluation of lunar calendar, a scientific approach is adopted in order to determine possible first lunar location above western horizon at about 30 minutes after sunset, which is considered for reference location and time. This research shows that, the available lunar calendars are mainly drawn on the basis of numerical difference considered as the only drift before now, known as a consequence of the difference between the Islamic calendar and the Gregorian calendar. In this project, harmonic drift in lunar dates against the Gregorian calendar is noticed as a secondary drift and possible cause of the discrepancy in lunar calendar. The anomaly is in cooperated in developing the lunar calendar, thus aided the development of a reliable lunar calendar that could project dates for many years without showing any discrepancies.I hope that this book will be exciting to beneficiaries who include educational institutions and research centers, as well as individual enthusiasts of astronomy.










The History of Imperial China


Book Description

A comprehensive introduction in English to Sinological methods and traditional Chinese historical writing. The time span ranges from earliest times to 1911, with special emphasis on the years between the third century B.C. and the eighteenth century. The author includes introductions to major reference works and biographical information, and explanations of such matters as converting traditional dates. In addition to standard histories, the survey covers biographical writing, historical and administrative geography, works on statecraft, archival sources, and Confucian, Buddhist, and Taoist writings.




Astronomy and Calendars – The Other Chinese Mathematics


Book Description

Presented from the viewpoint of the history of mathematics, this book explores both epistemological aspects of Chinese traditional mathematical astronomy and lunisolar calendrical calculations. The following issues are addressed: (1) connections with non-Chinese cultural areas; (2) the possibility or impossibility of using mathematics to predict astronomical phenomena, a question that was constantly raised by the Chinese from antiquity through medieval times; (3) the modes of representation of numbers, and in particular the zero, found in the context of Chinese calendrical calculations; and (4) a detailed analysis of lunisolar calendrical calculations. Fully worked-out examples and comparisons between the results of calculations and the content of Chinese historical calendars from various periods are provided. Traditional Chinese calendrical and mathematical astronomy consists of permanently reformed mathematical procedures designed to predict, but not explain, phenomena pertaining to astronomy and related areas. Yet, despite appearances, models of the mathematical techniques hidden behind this voluminous corpus reveal that they depend on a limited number of clear-cut mathematical structures. Although only a small fraction of these techniques have been fully studied, what is known surprisingly broadens our knowledge of the history of Chinese mathematics. Sinologists interested in the history of Chinese science, and anyone interested in the history of Chinese mathematics, the Chinese calendar, and the history of Chinese mathematical astronomy from its origin (104 BC) to its European reform (AD 1644) will find this book very useful. The present English language edition is a fully revised and updated version of the French original. Even though this is a research monograph in sinology, no particular sinological background is required, although a basic understanding of ‘concrete mathematics’ is needed. From the reviews of the French edition: This is a demanding, rigorous book to read ... worth the concentrated study it requires. The rewards are not only in the details but in the general overview that ...[it] provides. Joseph Dauben, EASTM, 2011 ...first Work in a Western language to turn to for anyone interested in the details of Chinese calendrical computations. Benno Van Dalen, ISIS, 2011 Martzloff’s careful scholarship and his overall look at the calendar beyond astronomical calculations, ..., make this book a most valuable contributions to a field of increasing interest.

Chinese History


Book Description

Endymion Wilkinson's bestselling manual of Chinese history has long been an indispensable guide to all those interested in the civilization and history of China. In this latest edition, now in a bigger format, its scope has been dramatically enlarged by the addition of one million words of new text. Twelve years in the making, the new manual introduces students to different types of transmitted, excavated, and artifactual sources from prehistory to the twentieth century. It also examines the context in which the sources were produced, preserved, and received, the problems of research and interpretation associated with them, and the best, most up-to-date secondary works. Because the writing of history has always played a central role in Chinese politics and culture, special attention is devoted to the strengths and weaknesses of Chinese historiography.
