Famous for his metal prosthetic nose, and for being associated with 'unlucky' days in Scandinavian folklore, Tycho Brahe (1546 1601) made the most accurate naked-eye astronomical measurements of his day. Cataloguing more than 1,000 new stars, his stellar and planetary observations helped lay the foundations of early modern astronomy. John Louis Emil Dreyer (1852 1926) was a fellow Dane, but he spent much of his working life in Ireland. When he was fourteen, he had read a book about Brahe and this inspired him to 'be an astronomer and nothing else'. First published in 1890, Dreyer's biography of his hero remained the definitive work for more than a century. He sets out to illuminate not simply the life of his subject, but also the lives and work of Brahe's contemporaries and the progress of science in the sixteenth century."

John Michell (1724-93) was a renowned English natural philosopher, astronomer and geologist. Originally published in 1918, this book presents a concise study of Michell's life and achievements, incorporating discussion of his contributions to geology, physics and astronomy. The text was written by Scottish geologist Archibald Geikie (1835-1924), following researches among the archives of the Royal Society and its dining club. This is a highly readable book that will be of value to anyone with an interest in Michell and his scientific achievements.

The text is composed, as far as possible, from their own words, using extracts from William Herschel's brief autobiographical notes and from Caroline's very full journals, as well as from letters. A variety of illustrative figures and an appendix section are also included. This book will be of value to anyone with an interest in the Herschels, astronomy and music.

This book presents previously unexamined connections between teaching practices and specific philosophical ideas, locating the prior beliefs and practical knowledge of early childhood practitioners in urban India within the broader social and historical religio-philosophical context.

This is a comparative ethnography of five Israeli schools that use state-of-the-art educational approaches to help change Israel's conflicted society. It gives an important glimpse of individuals and institutions that bravely operate as social and educational entrepreneurs, striving to change Israeli society.

By the end of the Twentieth century, formal schooling - once the privilege of male elites - had become accessible to women, the working class and some ethnic minorities. The essays in this volume explore the historical origins of this transformation, analyzing struggles Australia, Canada, China, Columbia, India, the United States, and South Africa.

Although astronomical guides were available in the early nineteenth century, they tended to come from continental presses and were rarely in English. This two-volume work by the clergyman and astronomer William Pearson (1767-1847) aimed, with brilliant success, to compile data from extant sources into one of the first English practical guides to astronomy. Most of the tables were updated and improved versions, and some were wholly reconstructed to streamline the calculation processes. Sir John Herschel dubbed it 'one of the most important and extensive works on that subject which has ever issued from the press', and for his efforts Pearson was awarded the gold medal of the Astronomical Society. First published in 1829, Volume 2 provides full descriptions of a range of astronomical instruments, alongside instructions for their use and some pertinent equations and tables. In the history of science, Pearson's work reflects the contemporary challenges of celestial study.

Retheorizing Religion in Nepal is an engaging and thought-provoking study of Religion in South Asia, with important insights for the study of religion and culture more broadly conceived. Grieve uses ethnographic material as well as poststructuralist and postcolonialist approaches to critique and expand religious studies as a discipline.

Revolution and Pedagogy explores the tensions between and within the processes of revolutionary pedagogical change and continuity. Contributors examine conventional topics such as school policies and curricula, as well as more non-traditional pedagogies such as public celebrations of holidays, participation in international exchange programs, and the incarceration of political activists.

This book brings in an international perspective on a much debated area, namely teacher education. Through narrative research, the chapters in this collection provide a wide variety of stories of discovery, transformation and hope in teaching and learning to teach.

This study offers a fresh reading of religious conversion by analyzing a variety of "missionaries" that sought to influence the Montagnard-Dega refugee. Thomas Pearson uses ethnographic and archival research to tell the story of cross-cultural contact in the highlands during the Vietnam War, Christian conversion, refugee exile, and the formation of the Dega refugee community in the United States. His insightful study considers not just evangelicals and Catholics, but humanitarian workers in the highlands, refugee resettlement volunteers in the United States, and the American Special Forces soldiers. This book makes the case that the Dega have appropriated the anthropological and religious discourses of this disparate group of missionaries to recreate themselves through a multivalent "conversion."

This collection of peace education efforts in conflict and post-conflict societies brings together an international group of scholars to offer the very latest theoretical and pedagogical developments. Rather than focus on ad hoc peace education efforts this book investigates the need for long term, systemic approaches and innovative pedagogies.

The non-Gaussianity in the primordial density fluctuations is a key feature to clarify the early Universe and it has been probed with the Cosmic Microwave Background (CMB) bispectrum. In recent years, we have treated the novel-type CMB bispectra, which originate from the vector- and tensor-mode perturbations and include the violation of the rotational or parity invariance. On the basis of our current works, this thesis provides the general formalism for the CMB bispectrum sourced by the non-Gaussianity in the scalar, vector and tensor-mode perturbations. Applying this formalism, we calculate the CMB bispectra from the two scalars and a graviton correlation and primordial magnetic fields, and then outline new constraints on these magnitudes. Furthermore, this formalism can be easily extended to the cases where the rotational or parity invariance is broken. We also compute the CMB bispectra from the scalar-mode non-Gaussianities with a preferred direction and the tensor-mode non-Gaussianities induced by the parity-violating Weyl cubic terms. Here, we show that these bispectra include unique signals, which any symmetry-invariant models can never produce.

Is the Earth the right model and the only universal key to understand habitability, the origin and maintenance of life? Are we able to detect life elsewhere in the universe by the existing techniques and by the upcoming space missions? This book tries to give answers by focusing on environmental properties, which are playing a major role in influencing planetary surfaces or the interior of planets and satellites. The book gives insights into the nature of planets or satellites and their potential to harbor life. Different scientific disciplines are searching for the clues to classify planetary bodies as a habitable object and what kind of instruments and what kind of space exploration missions are necessary to detect life. Results from model calculations, field studies and from laboratory studies in planetary simulation facilities will help to elucidate if some of the planets and satellites in our solar system as well as in extra-solar systems are potentially habitable for life.

Shrouded in poetry, the earliest accounts of Hindu astronomy can strike modern readers as obscure. They involve the marriage of the moon to twenty-seven princesses, a war between gods and giants, and shadows that give birth to planets. In this fascinating study, first published in Calcutta in 1823 and reissued here in the 1825 edition, John Bentley (c.1750 1824) strives to strip back the mythical aspects of the stories to reveal their foundations. He points out that early Hindu astronomers divided the night sky into twenty-seven sections; that a solar eclipse could have been described as an epic war between light and dark; and that Saturn is often observed in the Earth's shadow. Using data from modern astronomical tables, he dates events, texts and people, whether mythical or factual, as well as charting the history of Indian astronomy from its earliest records to its modern developments.

The year 2011 marked the 80th anniversary of Georges Lemaitre's primeval atom model of the universe, forerunner of the modern day Big Bang theory. Prompted by this momentous anniversary the Royal Astronomical Society decided to publish a volume of essays on the life, work and faith of this great cosmologist, who was also a Roman Catholic priest. The papers presented in this book examine in detail the historical, cosmological, philosophical and theological issues surrounding the development of the Big Bang theory from its beginnings in the pioneering work of Lemaitre through to the modern day. This book offers the best account in English of Lemaitre's life and work. It will be appreciated by professionals and graduate students interested in the history of cosmology.

Lassen Sie sich von Wolfgang Tschirk begeistern: Er gewahrt Ihnen einen unterhaltsamen Blick auf die Verstandesleistungen jener, die dem Laplaceschen Damon Stuck fur Stuck sein Geheimnis ablauschen. Um Macht und Schoenheit der Differentialgleichungen zu erleben, sollten Sie Affinitat zur Mathematik mitbringen und auch vor Formeln nicht zuruckschrecken. Aber Sie werden sehen: Entgegen ihrem Ruf sind Differentialgleichungen im Grunde leicht zu verstehen und oft sogar leicht zu loesen.

With the success of Cherenkov Astronomy and more recently with the launch of NASA's Fermi mission, very-high-energy astrophysics has undergone a revolution in the last years. This book provides three comprehensive and up-to-date reviews of the recent advances in gamma-ray astrophysics and of multi-messenger astronomy. Felix Aharonian and Charles Dermer address our current knowledge on the sources of GeV and TeV photons, gleaned from the precise measurements made by the new instrumentation. Lars Bergstroem presents the challenges and prospects of astro-particle physics with a particular emphasis on the detection of dark matter candidates. The topics covered by the 40th Saas-Fee Course present the capabilities of current instrumentation and the physics at play in sources of very-high-energy radiation to students and researchers alike. This book will encourage and prepare readers for using space and ground-based gamma-ray observatories, as well as neutrino and other multi-messenger detectors.

This volume shows how collective magnetic excitations determine most of the magnetic properties of itinerant electron magnets. Previous theories were mainly restricted to the Curie-Weiss law temperature dependence of magnetic susceptibilities. Based on the spin amplitude conservation idea including the zero-point fluctuation amplitude, this book shows that the entire temperature and magnetic field dependence of magnetization curves, even in the ground state, is determined by the effect of spin fluctuations. It also shows that the theoretical consequences are largely in agreement with many experimental observations. The readers will therefore gain a new comprehensive perspective of their unified understanding of itinerant electron magnetism.

The large telescope at Meudon has become legendary. When it was conceived, after 1870, astronomy as a whole was limited to visual observation. Knowledge of the sky was limited to what one could see, assisted only by optical means. The large telescopes produced at this time produced larger images, permitting close-up views: the Meudon telescope was able to accomplish this perfectly. At Meudon, which became the Mecca of visual observation, the major planets were examined in a way that no other telescope had previously been able to. The telescope monitored the state of their atmospheres and mapped the appearance of their surfaces. Through the telescope, one could obtain photographs showing the nuclei of comets, revealing their very small size, and by using an eyepiece one could measure the separation of double stars. With a marvellous little instrument, the polarimeter, the nature of clouds in planetary atmospheres has been determined, and the type of surface material identified. Many more results were obtained, while photography, universally adopted, revolutionized other knowledge about the world. The sensitive emulsion, combined with large aperture reflecting telescopes, revealed the deepness and richness of the cosmos. The vast telescope of Meudon, which was the largest refracting telescope in Europe, became a legendary instrument and was symbolic of a new way to practice astronomy. Audouin Dollfus, a renowned astronomer, describes the great years of the Meudon telescope. He gives us the entire story of this instrument, from the birth of the concept that drove Jules Janssen at the end of the nineteenth century, to the idea that French astronomy could provide an outstanding telescope which would approach the limits of technical and industrial resources. The telescope remained unchanged until 2006, when the first steps toward restoration and public reopening were taken.

One day, astrobiologists could make the most fantastic discovery of all time: the detection of complex extraterrestrial life. As space agencies continue to search for life in our Universe, fundamental questions are raised: are we awake to the revolutionary effects on human science, society and culture that alien contact will bring? And how is it possible to imagine the unknown? In this book, Mark Brake tells the compelling story of how the portrayal of extraterrestrial life has developed over the last two and a half thousand years. Taking examples from the history of science, philosophy, film and fiction, he showcases how scholars, scientists, film-makers and writers have devoted their energies to imagining life beyond this Earth. From Newton to Kubrick, and Lucian to H. G. Wells, this is a fascinating account for anyone interested in the extraterrestrial life debate, from general readers to amateur astronomers and undergraduate students studying astrobiology.

These are the proceedings of the Sant Cugat Forum 2nd Workshop on Cosmic-ray Induced Phenomenology in Stellar Environments, held April 16-19, 2012. The aim of this Workshop was to address the current knowledge and challenges of high-energy emission from stellar environments at all scales and provide a comprehensive review of the state of the field from the observational to the theoretical perspectives. In the meeting, the prospects for possible observations with planned instruments across the multi-wavelength spectrum were analyzed and also how they impact on our understanding of these systems.

The result of an exhaustive study of Sir Patrick Moore's observations of the Moon and planets for more than 60 years, this book is a fantastic companion to the extremely popular, "It Came From Outer Space Wearing an RAF Blazer!" written by the same author. Moore recorded his telescopic observations in his logbooks, which are reproduced and described here in detail, along with his sketches and notes. In this light, the author discusses the factors that caused Moore to switch from lunar observing to planetary and variable star observing. He has also included personal recollections and humorous anecdotes from Moore's friends and acquaintances, as well as a look at his best loved books. Further chapters describe Moore's foreign travels and correspondence with those back home. Lastly, the author has not neglected a few of Moore's most memorable television and radio appearances, which are examined along with a close up of what it was like to visit Moore's beloved home of Farthings in Selsey. Essentially, this is a book written by popular demand from the readers of the author's original biography, who craved more of Moore!
