The book concludes with eighteenth- and nineteenth-century applications of Newton's law, and the first explorations of the universe of stars. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable. Variable stars are those that change brightness.
Their variability may be due to geometric processes such as rotation, or eclipse by a companion star, or physical processes such as vibration, flares, or cataclysmic explosions. In each case, variable stars provide unique information about the properties of stars, and the processes that go on within them. This book provides a concise overview of variable stars, including a historical perspective, an introduction to stars in general, the techniques for discovering and studying variable stars, and a description of the main types of variable stars.
It ends with short reflections about the connection between the study of variable stars, and research, education, amateur astronomy, and public interest in astronomy. This book is intended for anyone with some background knowledge of astronomy, but is especially suitable for undergraduate students and experienced amateur astronomers who can contribute to our understanding of these important stars.
Score: 3. This comprehensive and engaging history of Switzerland traces the historical and cultural development of this fascinating but neglected European country from the end of the Dark Ages up to the present. The authors focus on the initial Confederacy of the Middle Ages; the religious divisions which threatened it after and its surprising survival amongst Europe's monarchies; the turmoil following the French Revolution and conquest, which continued until the Federal Constitution of ; the testing of the Swiss nation through the late nineteenth century and then two World Wars and the Depression of the s; and the unparalleled economic and social growth and political success of the post-war era.
The book concludes with a discussion of the contemporary challenges, often shared with neighbours, that shape the country today. A masterpiece of technical exposition, it was the basic textbook of astronomy for more than a thousand years, and still is the main source for our knowledge of ancient astronomy. This translation, based on the standard Greek text of Heiberg, makes the work accessible to English readers in an intelligible and reliable form.
It contains numerous corrections derived from medieval Arabic translations and extensive footnotes that take account of the great progress in understanding the work made in this century, due to the discovery of Babylonian records and other researches.
It is designed to stand by itself as an interpretation of the original, but it will also be useful as an aid to reading the Greek text. This book provides a comprehensive account of spectrographs from an historical perspective, from their theory and development over the last two hundred years, to the recent advances of the early twenty-first century.
The author combines the theoretical principles behind astronomical spectrograph design with their historical development. Spectrographs of all types are considered, with prism, grating or grism dispersing elements. The book contains several tables listing the most significant instruments, around references, and over images, making it an indispensable reference for professional astronomers, graduate students, advanced amateur astronomers, and historians of science.
For more than three thousand years, the science of astronomy depended on visible light. In just the last sixty years, radio technology has fundamentally altered how astronomers see the universe. In A Single Sky, the historian David Munns explains how the idea of the radio telescope emerged from a new scientific community uniting the power of radio with the international aspirations of the discipline of astronomy.
The radio astronomers challenged Cold War era rivalries by forging a united scientific community looking at a single sky. Saladis Free Download. Kerzner Free Download. Greene, Peter G.
