Pulsars, since their discovery in 1967, have been regarded as natural laboratories for the study of matter under extreme physical conditions of density, gravity and intensity of magnetic fields. In recent years, with a rapidly developing economy, China has made great achievements in the fields of cosmology, astronomy and astrophysics. This economic scenario, combined with China’s millennial tradition of seeking to expand the frontiers of knowledge, led to the planning and construction of several large radio telescopes and the launch of a series of deep space exploration satellites. As a concrete result of this broad effort, today China is gradually advancing to the forefront of scientific research and technological innovation in the field of Pulsar Astronomy. The main highlight of this book is to present the Five-hundred-meter Aperture Spherical Telescope (FAST) and its new discoveries and scientific results. To date, FAST has discovered more than 800 new pulsars through its galactic plane survey and drift sweep. The high-precision millisecond pulsars found by FAST can be used to detect extremely lowfrequency gravitational waves, establish pulsar timing patterns, and search for unknown objects in the solar system. For the vast majority of readers, this book undoubtedly represents a rich source of documentation, information and learning about pulsars and their impact on modern astrophysics and particularly about China’s contribution to new achievements in this area.

Free Download Giulio Magli, "Architecture, Astronomy and Sacred Landscape in Ancient Egypt"
English | ISBN: 1108729770 | 2019 | 284 pages | PDF | 12 MB
This book examines the interplay between astronomy and dynastic power in the course of ancient Egyptian history, focusing on the fundamental role of astronomy in the creation of the pyramids and the monumental temple and burial complexes. Bringing to bear the analytical tools of archaeoastronomy, a set of techniques and methods that enable modern scholars to better understand the thought, religion, and science of early civilizations, Giulio Magli provides in-depth analyses of the pyramid complexes at Giza, Abusir, Saqqara, and Dahshur, as well as of the Early Dynastic necropolis at Abydos and the magnificent new Kingdom Theban temples. Using a variety of data retrieved from study of the sky and measurements of the buildings, he reconstructs the visual, symbolic, and spiritual world of the ancient Egyptians and thereby establishes an intimate relationship among celestial cycles, topography, and architecture. He also shows how they were deployed in the ideology of the pharaoh’s power in the course of Egyptian history.

Free Download Radio Astronomy in Canada: Young Science in a Young Country
English | 2024 | ISBN: 3031129334 | 382 Pages | PDF EPUB (True) | 65 MB
Here is the tale of Canada’s intriguing development of the science of Radio Astronomy. In 1946 the lone figure of Arthur Covington started monitoring the radio emission of the Sun, a programme that continues to this day. By the 1960s Canada had progressed to constructing two radio observatories at either ends of the country (the DRAO and the ARO), and universities were coming onboard. The story continues through the dire times for these and follows their fortunes and fates right up to the present, with Canada now playing key roles in billion-dollar international telescope projects. It concludes with the construction and operation of Canada’s own transformational telescope, CHIME. Anecdotes and images throughout the book liven the story.

Studies on the Transmission of Medieval Mathematical Astronomy opens with a new survey of the transmission of Hellenistic astronomy, followed by two studies on how the notion of precession was treated by Babylonian, Greek, Indian, Arabic and Latin hands. Next is a survey of the astronomical tables that appeared in Latin during the 12th century, drawn mainly from Arabic and to some extent from Hebrew, as well as a special study of the Latin tables for London and Pisa drawn originally from the 10th-century Islamic astronomer al-Sufi. For the Sanskrit texts the focus is on the demonstration that the systems were founded on observations made in India, even though much of the theory was Greek in origin. On Byzantine material there are studies of the Persian Syntaxis whose source lay in the Persian Zij-i Ilkhani, and of the diverse materials drawn on by Gemistus Plethon. Mercier’s work shows that there is a unity in medieval astronomy in spite of the great diversity in cultural settings, which included South and Central Asia, the Middle East, Byzantium, and Europe. The texts were recorded in all the major languages of this great region, from Sanskrit to Latin, over a period of time stretching from the late classical world to late medieval Europe. Yet these astronomical texts have much in common, drawn from the whole apparatus of Ptolemaic, or rather more inclusively, Greek astronomy. Transmission is demonstrated partly by the continuity of technical terms, and partly by the conservation and development of numerical parameters.

Free Download A.I. Sabra, "Optics, Astronomy and Logic: Studies in Arabic Science and Philosophy "
English | ISBN: 0860784355 | | 337 pages | EPUB, PDF | 12 MB + 34 MB
Running through the articles in this volume is the theme of the appropriation and subsequent naturalization of Greek science by scholars in the world of medieval Islam. The opening paper presents the historiography of this process, and the focus is then placed on Ibn al-Haytham, one of the most original and influential figures of the 11th century, and in particular in his contribution to the science of optics, both mathematical and experimental, and the psychology of vision. Professor Sabra then continues the analysis of how Greek thought was developed in the Islamic world with two studies of work based on Euclid’s geometry and two on critiques of Ptolemaic astronomy. The final articles turn specifically to questions in the history of logic – Aristotelian syllogism, and Avicenna’s views on the subject – matter of logic.

Free Download Calendars and Years: Astronomy and Time in the Ancient Near East by John M. Steele
English | October 8, 2007 | ISBN: 1842173022 | 176 pages | MOBI | 7.89 Mb
Dates form the backbone of written history. But where do these dates come from? Many different calendars were used in the ancient world. Some of these calendars were based upon observations or calculations of regular astronomical phenomena, such as the first sighting of the new moon crescent that defined the beginning of the month in many calendars, while others incorporated schematic simplifications of these phenomena, such as the 360-day year used in early Mesopotamian administrative practices in order to simplify accounting procedures. Historians frequently use handbooks and tables for converting dates in ancient calendars into the familiar BC/AD calendar that we use today. But very few historians understand how these tables have come about, or what assumptions have been made in their construction. The seven papers in this volume provide an answer to the question what do we know about the operation of calendars in the ancient world, and just as importantly how do we know it? Topics covered include the ancient and modern history of the Egyptian 365-day calendar, astronomical and administrative calendars in ancient Mesopotamia, and the development of astronomical calendars in ancient Greece. This book will be of interest to ancient historians, historians of science, astronomers who use early astronomical records, and anyone with an interest in calendars and their development.
