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 Moon written by Viorel Badescu and published by Springer Science & Business Media. This book was released on 2012-03-22 with total page 771 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Earth has limited material and energy resources. Further development of the humanity will require going beyond our planet for mining and use of extraterrestrial mineral resources and search of power sources. The exploitation of the natural resources of the Moon is a first natural step on this direction. Lunar materials may contribute to the betterment of conditions of people on Earth but they also may be used to establish permanent settlements on the Moon. This will allow developing new technologies, systems and flight operation techniques to continue space exploration. In fact, a new branch of human civilization could be established permanently on Moon in the next century. But, meantime, an inventory and proper social assessment of Moon’s prospective energy and material resources is required. This book investigates the possibilities and limitations of various systems supplying manned bases on Moon with energy and other vital resources. The book collects together recent proposals and innovative options and solutions. It is a useful source of condensed information for specialists involved in current and impending Moon-related activities and a good starting point for young researchers.
Download or read book On Sunspots written by Galileo Galilei and published by University of Chicago Press. This book was released on 2010-10-30 with total page 431 pages. Available in PDF, EPUB and Kindle. Book excerpt: Galileo’s telescopic discoveries, and especially his observation of sunspots, caused great debate in an age when the heavens were thought to be perfect and unchanging. Christoph Scheiner, a Jesuit mathematician, argued that sunspots were planets or moons crossing in front of the Sun. Galileo, on the other hand, countered that the spots were on or near the surface of the Sun itself, and he supported his position with a series of meticulous observations and mathematical demonstrations that eventually convinced even his rival. On Sunspots collects the correspondence that constituted the public debate, including the first English translation of Scheiner’s two tracts as well as Galileo’s three letters, which have previously appeared only in abridged form. In addition, Albert Van Helden and Eileen Reeves have supplemented the correspondence with lengthy introductions, extensive notes, and a bibliography. The result will become the standard work on the subject, essential for students and historians of astronomy, the telescope, and early modern Catholicism.

Download or read book Meteorites written by J. T. Wasson and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: My goal in writing this book was to provide an introduction to meteorite science and a handbook on meteorite classification. Insofar as I succeeded it should prove useful both to the practicing professional and to university students at the upper-division and graduate levels. I originally intended the book to be nearly twice as long. The second half was to be a review of properties relating to the origin of each group of meteorites. Chapter XVIII is an example of how these later chapters would have looked, although most would not have been as interpretative. These chapters would have been useful chiefly to meteorite researchers looking for a quick summary of group properties; they were not written because of lack of time. Perhaps I will start to prepare this "second volume" in a year or so when my family and I have recovered from the preparation of the present volume. Although some parts of the classification portion are mildly icono clastic, I have attempted either to avoid the inclusion of speculative interpretations or to flag them with a caveat to the reader. I have relaxed these principles somewhat in Chapter XVIII to conserve space, but even there the discussion of alternative speculations should give the reader a feeling for the degree of uncertainty attached.

Available in PDF, EPUB and Kindle. Book excerpt: This book stimulates thinking on the topic of detrimental environmental change and how research psychologists can help to address the problem. In addition to reporting environmentally relevant psychological research, the author identifies the most pressing questions from an environmental point of view. Psychology and Environmental Change: *focuses on ways in which human behavior contributes to the problem; *deals with the assessment and change of attitudes and with studies of change of behavior; *proposes ways in which psychological research can contribute to making technology and its products more environmentally benign; and *introduces topics such as consumption, risk assessment, cost-benefit and tradeoff analyses, competition, negotiation, and policymaking, and how they relate to the objective of protecting the environment.

Download or read book Cosmogenic Radionuclides written by Jürg Beer and published by Springer Science & Business Media. This book was released on 2012-01-19 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cosmogenic radionuclides are radioactive isotopes which are produced by natural processes and distributed within the Earth system. With a holistic view of the environment the authors show in this book how cosmogenic radionuclides can be used to trace and to reconstruct the history of a large variety of processes. They discuss the way in which cosmogenic radionuclides can assist in the quantification of complex processes in the present-day environment. The book aims to demonstrate to the reader the strength of analytic tools based on cosmogenic radionuclides, their contribution to almost any field of modern science, and how these tools may assist in the solution of many present and future problems that we face here on Earth. The book provides a comprehensive discussion of the basic principles behind the applications of cosmogenic (and other) radionuclides as environmental tracers and dating tools. The second section of the book discusses in some detail the production of radionuclides by cosmic radiation, their transport and distribution in the atmosphere and the hydrosphere, their storage in natural archives, and how they are measured. The third section of the book presents a number of examples selected to illustrate typical tracer and dating applications in a number of different spheres (atmosphere, hydrosphere, geosphere, biosphere, solar physics and astronomy). At the same time the authors have outlined the limitations of the use of cosmogenic radionuclides. Written on a level understandable by graduate students without specialist skills in physics or mathematics, the book addresses a wide audience, ranging from archaeology, biophysics, and geophysics, to atmospheric physics, hydrology, astrophysics and space science.

Available in PDF, EPUB and Kindle. Book excerpt: 'An irresistible page-turner that reads like the most compelling, sleep defying fiction' TIME OUT One was an architect. The other a serial killer. This is the incredible story of these two men and their realization of the Chicago World's Fair of 1893, and its amazing 'White City'; one of the wonders of the world. The architect was Daniel H. Burnham, the driving force behind the White City, the massive, visionary landscape of white buildings set in a wonderland of canals and gardens. The killer was H. H. Holmes, a handsome doctor with striking blue eyes. He used the attraction of the great fair - and his own devilish charms - to lure scores of young women to their deaths. While Burnham overcame politics, infighting, personality clashes and Chicago's infamous weather to transform the swamps of Jackson Park into the greatest show on Earth, Holmes built his own edifice just west of the fairground. He called it the World's Fair Hotel. In reality it was a torture palace, a gas chamber, a crematorium. These two disparate but driven men are brought to life in this mesmerizing, murderous tale of the legendary Fair that transformed America and set it on course for the twentieth century . . .
