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.

Available in PDF, EPUB and Kindle. Book excerpt: The cycle of day and night and the cycle of seasons are two familiar natural cycles around which many human activities are organized. But is there a third natural cycle of importance for us humans? On 13 March 1989, six million people in Canada went without electricity for many hours: a large explosion on the sun was discovered as the cause of this blackout. Such explosions occur above sunspots, dark features on the surface of the Sun that have been observed through telescopes since the time of Galileo. The number of sunspots has been found to wax and wane over a period of 11 years. Although this cycle was discovered less than two centuries ago, it is becoming increasingly important for us as human society becomes more dependent on technology. For nearly a century after its discovery, the cause of the sunspot cycle remained completely shrouded in mystery. The 1908 discovery of strong magnetic fields in sunspots made it clear that the 11-year cycle is the magnetic cycle of the sun. It is only during the last few decades that major developments in plasma physics have at last given us the clue to the origins of the cycle and how the large explosions affecting the earth arise. Nature's Third Cycle discusses the fascinating science behind the sunspot cycle, and gives an insider's perspective of this cutting-edge scientific research from one of the leaders of the field.

Available in PDF, EPUB and Kindle. Book excerpt: Mediation, monarchy, and Louis XIV's attempts to legitimize his reign In order to assert his divine right, Louis XIV missed no opportunity to identify himself as God’s representative on earth. However, in Sunspots and the Sun King Ellen McClure explores the contradictions inherent in attempting to reconcile the logical and mystical aspects of divine right monarchy. McClure analyzes texts devoted to definitions of sovereignty, presents a meticulous reading of Louis XIV’s memoirs to the crown prince, and offers a novel analysis of diplomats and ambassadors as the mediators who preserved and transmitted the king’s authority. McClure asserts that these discussions, ranging from treatises to theater, expose incommensurable models of authority and representation permeating almost every aspect of seventeenth-century French culture.

Available in PDF, EPUB and Kindle. Book excerpt: “Observing the Sun” is for amateur astronomers at all three levels: beginning, intermediate, and advanced. The beginning observer is often trying to find a niche or define a specific interest in his hobby, and the content of this book will spark that interest in solar observing because of the focus on the dynamics of the Sun. Intermediate and advanced observers will find the book invaluable in identifying features (through photos, charts, diagrams) in a logical, orderly fashion and then guiding the observer to interpret the observations. Because the Sun is a dynamic celestial body in constant flux, astronomers rarely know for certain what awaits them at the eyepiece. All features of the Sun are transient and sometimes rather fleeting. Given the number of features and the complex life cycles of some, it can be a challenging hobby. “Observing the Sun” provides essential illustrations, charts, and diagrams that depict the forms and life cycles of the numerous features visible on the Sun.

Book excerpt: Climate change has been a perplexing problem for years. In Cold Sun, author John L. Casey, a former White House national space policy advisor, NASA headquarters consultant, and space shuttle engineer tells the truth about ominous changes taking place in the climate and the Sun. Casey's research into the Sun's activity, which began four years ago, resulted in discovery of a solar cycle that is now reversing from its global warming phase to that of dangerous global cooling for the next thirty years or more. This new cold climate will dramatically impact the world's citizens. In Cold Sun, he provides evidence of the following: / The end of global warming / The beginning of a solar hibernation, a historic reduction in the energy output of the Sun / A long-term drop in the Earth's temperatures / The start of the next climate change to decades of dangerously cold weather / The high probability of record earthquakes and volcanic eruptions A sobering look at the Earth's future, Cold Sun predicts worldwide, crop-destroying cold; food shortages and riots in the United States and abroad; signifi cant global loss of life; and social, political, and economic upheaval.

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.
