Book Description
Cometography is the most complete and comprehensive collection of data on comets available. It comes in four self-contained sequential volumes and this, the first, covers ancient times through to the end of the eighteenth century. Cometography uses the most reliable orbits known to determine all the key parameters of each well observed comet. Cometography also provides nontechnical details to help the reader understand how the comet may have influenced various cultures at the time of its appearance. All the information in Cometography has been sourced directly from the original documents, including European monastic histories, Roman, Greek and Muslim texts, Chinese, Japanese and Korean scripts. In many cases, dates of important historical events can be corrected based on the appearance of a comet and identified using this book. Cometography will be valuable to historians of science as well as providing amateur and professional astronomers with a definitive reference on comets through the ages.

Book Description
For many astronomers, the holy grail of observation is to discover a comet, not least because comets always bear the name of their discoverer! Hunting and Imaging Comets was written for comet hunters and digital imagers who want to discover, rediscover, monitor, and make pictures of comets using astronomical CCD cameras and DSLRs. The old days of the purely visual comet hunter are pretty much over, but this is not to say that amateurs have lost interest in finding comets. The books also covers the discovery of comet fragments in the SOHO image data, CCD monitoring of older comets prone to violent outbursts, the imaging of new NEOs (Near Earth Objects) that have quite often been revealed as comets - not asteroids - by amateur astronomers, and the finding of recent comets impacting Jupiter.

Book Description
Very little is known about the battle of Carham, fought between the Scots and Northumbrians in 1018. The leaders were probably Máel Coluim II, king of Scotland, and Uhtred of Bamburgh, earl or ealdorman in Northumbria. The outcome of the battle was a victory for the Scots, seen by some as a pivotal event in the expansion of the Scottish kingdom, the demise of Northumbria and the Scottish conquest of 'Lothian'. The battle also removed a potentially significant source of resistance to the recent conqueror of England, Cnut. This collection of essays by a range of subject specialists explores the battle in its context, bringing new understanding of this important and controversial historical event. Topics covered include: Anglo-Scottish relations, the political character and ecclesiastical organisation of the Northumbrian territory ruled by Uhtred, material from the Chronicles and other historical records that brings the era to light, and the archaeological and sculptural landscape of the tenth- and eleventh-century Tweed basin, where the battle took place.

Book Description
Comets have inspired wonder, excitement and even fear ever since they were first observed. But they are important members of the solar system, that contain material from early in the life of the system, held in deep-freeze. This makes them key in our understanding of the formation and evolution of many Solar System bodies. Recent ground- and space-based observations have changed much in our understanding of comets. Comets, and How to Observe Them gives a summary of our current knowledge and describes how amateur astronomers can contribute to the body of scientific knowledge of comets. This book contains many practical examples of how to construct comet light-curves, measure how fast a comet’s coma expands, and determine the rotation period of the nucleus. All these examples are illustrated with drawings and photographs. Because of their unpredictable nature comets are always interesting and sometime spectacular objects to observe and image. The second part of the book therefore takes the reader through the key observing techniques that can be used with commercially available modern observing equipment, from basic observations to more scientific measurements.

Book Description
A groundbreaking argument about the link between autism and ingenuity. Why can humans alone invent? In The Pattern Seekers, Cambridge University psychologist Simon Baron-Cohen makes a case that autism is as crucial to our creative and cultural history as the mastery of fire. Indeed, Baron-Cohen argues that autistic people have played a key role in human progress for seventy thousand years, from the first tools to the digital revolution. How? Because the same genes that cause autism enable the pattern seeking that is essential to our species's inventiveness. However, these abilities exact a great cost on autistic people, including social and often medical challenges, so Baron-Cohen calls on us to support and celebrate autistic people in both their disabilities and their triumphs. Ultimately, The Pattern Seekers isn't just a new theory of human civilization, but a call to consider anew how society treats those who think differently.

Book Description
This textbook gives a lively introduction to the search for extraterrestrial life. It is a guidebook to understanding the possibility of life elsewhere, pointing out landmarks and providing background information to facilitate further exploration of those areas of most interest to the reader. We are a planet of winners – winners of a cosmic lottery that has been in play since the universe began approximately 13.7 billion years ago. Our winnings include sentience and an underlying unease that has driven us to contemplate our place in the universe and the possibility of finding kindred spirits in the cosmos spreading out before us. To understand our origins and the possibility of life beyond Earth, we must look back and retrace the steps that have brought us to this point in space and time. In doing so, we will find the investigation of life to be a unifying theme in nature, requiring us to touch on all branches of the tree of knowledge. Using the Drake Equation as a theme, we begin with an overview of the topic and then go into the story of how we have acquired, or plan to acquire, the knowledge to solve it. As we make our journey, we will encounter some very interesting people – some you will likely know, while others may be new to you. Keep an open mind and allow this text to be your guide. Written in an engaging style, this textbook provides a foundational understanding of the rapidly advancing fields associated with the search for life in the universe. Each chapter includes illustrative figures and review questions for self-study. It will appeal to professionals, researchers, instructors, and undergraduate students, as well as anyone with an interest in astrophysics or astrobiology.

Book Description
His grandfather was the bloodthirsty Mongol leader Genghis Khan, his mother a Christian princess. Groomed from childhood for a position of authority, Khubilai snatched the position of Great Khan, becoming the overlord of a Mongol federation that stretched from the Balkans to the Korean coast. His armies conquered the Asian kingdom of Dali and brought down the last defenders of imperial China. Khubilai Khan presided over a glorious Asian renaissance, attracting emissaries from all across the continent, and opening his civil service to 'men with coloured eyes' - administrators from the far west. His reign began the glorious Yuan dynasty that ruled over China for only ninety years, but had a profound impact on Asian history, from international trade to cultural revolution. Jonathan Clements's insightful biography into the life and times of one of China's greatest leaders is a fascinating introduction to an important era, uncovering the man behind Marco Polo's mythic portrait.

Book Description
One of the most ambitious works of paranormal investigation of our time, here is an unprecedented compendium of pre-twentieth-century UFO accounts, written with rigor and color by two of today's leading investigators of unexplained phenomena. In the past century, individuals, newspapers, and military agencies have recorded thousands of UFO incidents, giving rise to much speculation about flying saucers, visitors from other planets, and alien abductions. Yet the extraterrestrial phenomenon did not begin in the present era. Far from it. The authors of Wonders in the Sky reveal a thread of vividly rendered-and sometimes strikingly similar- reports of mysterious aerial phenomena from antiquity through the modern age. These accounts often share definite physical features- such as the heat felt and described by witnesses-that have not changed much over the centuries. Indeed, such similarities between ancient and modern sightings are the rule rather than the exception. In Wonders in the Sky, respected researchers Jacques Vallee and Chris Aubeck examine more than 500 selected reports of sightings from biblical-age antiquity through the year 1879-the point at which the Industrial Revolution deeply changed the nature of human society, and the skies began to open to airplanes, dirigibles, rockets, and other opportunities for misinterpretation represented by military prototypes. Using vivid and engaging case studies, and more than seventy-five illustrations, they reveal that unidentified flying objects have had a major impact not only on popular culture but on our history, on our religion, and on the models of the world humanity has formed from deepest antiquity. Sure to become a classic among UFO enthusiasts and other followers of unexplained phenomena, Wonders in the Sky is the most ambitious, broad-reaching, and intelligent analysis ever written on premodern aerial mysteries.
