Design, Development and Analysis of Lunar Crescent Visibility Criterion With Python


Book Description

The analysis of lunar crescent visibility criterion is vital in providing a comparative insight for predicting the visibility and suitability for Hijri calendar determination. While there have been previous attempts to measure the performance of lunar crescent visibility criterion, these attempts only apply to a singular analysis and not a comparative examination. Design, Development and Analysis of Lunar Crescent Visibility Criterion with Python explores the development of an analysis tool for lunar crescent visibility criterion using an integrated lunar crescent visibility database. The analysis tool, called HilalPy and HilalObs, was developed in the form of a Python library, so that it can be integrated into other software and webpages to enable deployment into various operating systems. This book will provide useful insights for the future development of lunar crescent visibility criterion, particularly for calendrical purposes. Key Features: ● Presents an analysis tool for lunar crescent visibility based on an integrated lunar crescent report database. ● Offers researchers and practitioners the capability to perform comparative analyses of the percentage of reliability in lunar crescent visibility criteria, thereby contributing to the construction of robust criteria for determining the Hijri calendar. ● Provides a comprehensive resource for researchers, students, policymakers, and practitioners involved in the determination of the Hijri calendar.




Astronomy and Astrology in the Islamic World


Book Description

It was the astronomers and mathematicians of the Islamic world who provided the theories and concepts that paved the way from the geocentric theories of Claudius Ptolemy in the second century AD to the heliocentric breakthroughs of Nicholas Copernicus and Johannes Kepler in the sixteenth and seventeenth centuries. Algebra, the Arabic numeral system, and trigonometry: all these and more originated in the Muslim East and undergirded an increasingly accurate and sophisticated understanding of the movements of the Sun, Moon, and planets. This nontechnical overview of the Islamic advances in the heavenly sciences allows the general reader to appreciate (for the first time) the absolutely crucial role that Muslim scientists played in the overall development of astronomy and astrology in the Eurasian world.




Science and Technology from Global and Historical Perspectives


Book Description

This book provides science and technology ethos to a literate person. It starts with a rather detailed treatment of basic concepts in human values, educational status and domains of education, development of science and technology and their contributions to the welfare of society. It describes ways and means of scientific progresses and technological advancements with their historical perspectives including scientific viewpoints of contributing scientists and technologists. The technical, social, and cultural dimensions are surveyed in relation to acquisition and application of science, and advantages and hindrances of technological developments. Science and Technology is currently taught as a college course in many universities with the intention to introduce topics from a global historical perspective so that the reader shall stretch his/her vision by mapping the past to the future. The book can also serve as a primary reference for such courses.

The Mongols in Iran


Book Description

This book explores the administration of Iran under Mongol rule through taxation and monetary policy. A consistent development is evident only from abundant numismatic material, from the conquest of Samarqand by Chingiz Khan to the reign of the penultimate ruler, Uljaytu. In many cases, the individuals responsible for initiating and conducting the policies can be identified from the histories or remarks of the mint master. The structure of the empire is clearly demarcated by mint production, coin styles and type of metal. This illuminates many controversial historical points such as the meaning and function of an Il-khan and the establishment of the Toluid dynasty under Hulagu. The Mongols broke the crust of an inflexible and archaic Islamic monetary tradition that had hampered economic development by encouraging extensive trade and the sciences (especially astronomy and higher mathematics) through determined and always pragmatic programmes.




Court and Cosmos


Book Description

Rising from humble origins as Turkish tribesmen, the powerful and culturally prolific Seljuqs—an empire whose reach extended from Central Asia to the eastern Mediterranean—dominated the Islamic world from the eleventh to the fourteenth century. Court and Cosmos: The Great Age of the Seljuqs examines the roots and impact of this formidable dynasty, featuring some 250 objects as evidence of the artistic and cultural flowering that occurred under Seljuq rule. Beginning with an historical overview of the empire, from its early advances into Iran and northern Iraq to the spread of its dominion into Anatolia and northern Syria, Court and Cosmos illuminates the splendor of Seljuq court life. This aura of luxury extended to a sophisticated new elite, as both sultans and city dwellers acquired dazzling glazed ceramics and metalwork lavishly inlaid with silver, copper, and gold. Advances in science and technology found parallels in a flourishing interest in the arts of the book, underscoring the importance the Seljuqs placed on the scholarly and literary life. At the same time, the unrest that accompanied warfare between the Seljuqs and their enemies as well as natural disasters and unexplainable celestial phenomena led people to seek solace in magic and astrology, which found expression in objects adorned with zodiacal and talismanic imagery. These popular beliefs existed alongside devout adherence to Islam, as exemplified by exquisitely calligraphed Qur’ans and an array of building inscriptions and tombstones bearing verses from the holy book. The great age of the Seljuqs was one that celebrated magnificence, be it of this world or in the celestial realm. By revealing the full breadth of their artistic achievement, Court and Cosmos provides an invaluable record of the Seljuqs’ contribution to the cultural heritage of the Islamic world.
