With over 150,000 copies sold since its first publication, this is one of the most popular astronomy books of all time. This unique guidebook to the night sky shows you how to observe a host of celestial wonders. Its distinct format of object-by-object spreads illustrates how deep-sky objects and planets actually look through a small telescope, while its large pages and spiral binding allow for use outside. Along with updated star names and astronomical information, this new edition provides links to a dedicated webpage with up-to-date tables and images, and an improved planets chapter. The many Dobsonian-friendly images and small telescope views have been revised to account for changes in modern telescope technology, such as larger field of view eyepieces. With dedicated chapters on Northern and Southern Hemisphere objects, it's never been easier to explore the night sky, wherever you are.

You are reading the word "now" right now. But what does that mean? "Now" has bedeviled philosophers, priests, and modern-day physicists from Augustine to Einstein and beyond. In Now, eminent physicist Richard A. Muller takes up the challenge. He begins with remarkably clear explanations of relativity, entropy, entanglement, the Big Bang, and more, setting the stage for his own revolutionary theory of time, one that makes testable predictions. Muller's monumental work will spark major debate about the most fundamental assumptions of our universe, and may crack one of physics' longest-standing enigmas.

The extraordinary life of Bernard Lovell began before the First World War and his story encompasses many of the great events of last hundred years: the Second World War, the invention of radio astronomy, the space race, the Moon landings, the exploration of the Solar System, the Cold War, the Cuban missile crisis and the defence of Britain against nuclear attack. It can now be revealed that he was also a spy. "He ranks as one of the great visionary leaders of science," Martin Rees, the Astronomer Royal, said of him. The great radio telescope which Lovell built became and remains one of the most important scientific instruments in the World. The Jodrell Bank Observatory and the Lovell Telescope have held their place at the frontier of research for fifty five years. This book seeks to explore succinctly and accessibly Lovell's life and achievements in the scientific and political context of the time. His legacy remains great, as can be seen from the extensive media coverage and personal tributes that his death in 2012 attracted all over the world. With the seventieth anniversaries of many wartime events in which he played a crucial role, as well as the recent declassification of information relating to his activities as an agent in the Cold War, this biography is sure to have a broad and timely interest.

Body and Cosmos is a collection of articles published on the occasion of the 70th birthday of Professor Emeritus Kenneth G. Zysk. The articles revolve thematically around the early Indian medical and astral sciences, which have been at the center of Professor Zysk's long and esteemed career within the discipline of Indology. The volume is divided into three parts. The first part is devoted to the medical sciences, the second part to the astral sciences, and the third part to cross-cultural interactions between India and the West, which runs like an undercurrent throughout the work of Professor Zysk. The articles are written by internationally renowned Indological scholars and will be of value to students and researchers alike.

Calendars in the Making investigates the origins of calendars we are most familiar with today, yet whose early histories, in the Roman and medieval periods, are still shrouded in obscurity. It examines when the seven-day week was standardized and first used for dating and time reckoning, in Jewish and other constituencies of the Roman Empire; how the Christian liturgical calendar was constructed in early medieval Europe; and how and when the Islamic calendar was instituted. The volume includes studies of Roman provincial calendars, medieval Persian calendar reforms, and medieval Jewish calendar cycles. Edited by Sacha Stern, it presents the original research of a team of leading experts in the field. Contributors are: Francois de Blois, Ilaria Bultrighini, Sacha Stern, Johannes Thomann, Nadia Vidro, Immo Warntjes.
