Download or read book The Sun Recorded Through History written by J.M. Vaquero and published by Springer Science & Business Media. This book was released on 2009-04-21 with total page 382 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Sun is nowadays observed using di?erent techniques that provide an almost instantaneous 3-D map of its structure. Of particular interest is the studyofthevariabilityinthesolaroutputproducedbythedissipationofm- netic energy on di?erent spatial and temporal scales – the so-called magnetic activity. The 11-year cycle is the main feature describing this phenomenon. Apart from its intrinsic scienti?c interest, this topic is worth studying because of the interaction of such processes with the terrestrial environment. A ?eet of space and ground-based observatories are currently monitoring the behaviour of our star on a daily basis. However, solar activity varies not only on this decadal time-scale, as has been attested mainly through two methods: (a) records of the number of sunspots observed on the solar surface from 1610, and (b) the records of 14 10 cosmogenic isotopes, such as Cand Be, measured in tree-rings and i- cores, respectively. The study of the long-term behaviour of solar activity may be comp- mented by the study of historical accounts describing phenomena directly or indirectly related to solar activity. Numerous scienti?c and non-scienti?c d- uments have reported these events and we can make use of them as a proxy of solar activity in past times.
Download or read book A History of Western Astrology written by S. J. Tester and published by Boydell & Brewer Ltd. This book was released on 1987 with total page 274 pages. Available in PDF, EPUB and Kindle. Book excerpt: Superb general account.' Times Literary Supplement The story of the history of Western astrology begins with the philosophers of Greece in the 5th century BC. To the magic and stargazing of Egypt the Greeks added numerology, geometryand rational thought. The philosophy of Plato and later of the Stoics made astrology respectable, and by the time Ptolemy wrote his textbook the Tetrabiblos, in the second century AD, the main lines of astrological practice as it is known today had already been laid down. In future centuries astrology shifted to Islam only to return to the West in medieval times where it flourished until the shift of ideas during the Renaissance.

Download or read book Early Solar Physics written by A. J. Meadows and published by Elsevier. This book was released on 2016-01-21 with total page 325 pages. Available in PDF, EPUB and Kindle. Book excerpt: Early Solar Physics reviews developments in solar physics, particularly the advent of solar spectroscopy and the discovery of relationships between the various layers of the solar atmosphere and between the different forms of solar activity. Topics covered include solar observations during 1843; chemical analysis of the solar atmosphere; the spectrum of a solar prominence; and the solar eclipse of December 12, 1871. Spectroscopic observations of the sun are also presented. This book is comprised of 30 chapters and begins with an overview of ideas about the sun in the mid-nineteenth century, followed by a summary of progress in astronomy between 1850 and 1900, including observations of the solar surface, sunspots, and solar flares. The founding of the Mount Wilson Solar Observatory is cited. Observations of the sun made with solar spectroscopy are presented, including those of the sun's temperature. The results of a detailed examination of spectra photographed during the solar eclipse of January 22, 1898 are also discussed. The final chapter examines the magnetic properties of the earth and sun. This monograph will be a useful resource for astronomers, astrophysicists, and those interested in discovering many aspects of the sun.
Download or read book The Routledge Handbook of Spanish Language Teaching written by Javier Muñoz-Basols and published by Routledge. This book was released on 2018-10-17 with total page 702 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Routledge Handbook of Spanish Language Teaching: metodologías, contextos y recursos para la enseñanza del español L2, provides a comprehensive, state-of-the-art account of the main methodologies, contexts and resources in Spanish Language Teaching (SLT), a field that has experienced significant growth world-wide in recent decades and has consolidated as an autonomous discipline within Applied Linguistics. Written entirely in Spanish, the volume is the first handbook on Spanish Language Teaching to connect theories on language teaching with methodological and practical aspects from an international perspective. It brings together the most recent research and offers a broad, multifaceted view of the discipline. Features include: Forty-four chapters offering an interdisciplinary overview of SLT written by over sixty renowned experts from around the world; Five broad sections that combine theoretical and practical components: Methodology; Language Skills; Formal and Grammatical Aspects; Sociocultural Aspects; and Tools and Resources; In-depth reflections on the practical aspects of Hispanic Linguistics and Spanish Language Teaching to further engage with new theoretical ideas and to understand how to tackle classroom-related matters; A consistent inner structure for each chapter with theoretical aspects, methodological guidelines, practical considerations, and valuable references for further reading; An array of teaching techniques, reflection questions, language samples, design of activities, and methodological guidelines throughout the volume. The Routledge Handbook of Spanish Language Teaching contributes to enriching the field by being an essential reference work and study material for specialists, researchers, language practitioners, and current and future educators. The book will be equally useful for people interested in curriculum design and graduate students willing to acquire a complete and up-to-date view of the field with immediate applicability to the teaching of the language.

Download or read book Coronal Holes and Solar Wind Acceleration written by John Kohl and published by Springer Science & Business Media. This book was released on 1999-08-31 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: The SOHO-7 Workshop was held from 28 September through 1 October 1998 at the Asticou Inn in Northeast Harbor, Maine. The primary topic of this Workshop was the impact of SOHO observations on our understanding of the nature and evolution of coronal holes and the acceleration and composition of the solar wind. The presentations and discussions occasionally went beyond this topic to include the impact of the reported research on other solar structures and the heliosphere. SOHO (the Solar and Heliospheric Observatory), a project of international cooperation between ESA and NASA, was launched in December 1995 and began its science operations during the first few months of 1996. To many solar and space physicists, it was a great advantage that SOHO began itscomprehensive look at the Sun during the 1996 solar minimum. The qualitatively simple two-phase corona, with polar coronal holes expanding into the high-speed solar wind, and a steady equatorial streamer belt related somehow to the stochastic slow-speed solar wind, allowed various SOHO diagnostics to be initiated with a reasonably well understoodcircumsolar geometry. The analysis of subsequentSOHO measurements made during the rising phase of solar cycle 23 will continue to benefit from what has been learned from the first two years of data.
Download or read book The Enigma of Sunspots written by Judit Brody and published by . This book was released on 2002 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sunspots are dark areas on the Sun's surface, some as large as 50,000 miles in diameter. This text charts the history of our efforts to understand them, and the lives and quarrels of those astronomers who first charted their mysterious patterns and whose records are still of vital importance.
