Book Description
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.

Book Description
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.

AND Their Effects byHARLAN TRUE STETSON Research Associate at the Massachusetts Institute of Technology Author of B STARS AND THE STAJLS Yorfc WHITTLESEY HOUSE London MCGRAW-HILL BOOK COMPANY, INC. of and trireless i t tie cii Sciilt field of solar - t erTes trial FOREWARNING THE near approach of another sunspot maximum with the accompanying interest shown by the press and the general public gives the occasion for a book on sunspot s. So much has been said about the possibilities of sunspots affecting the earth and human affairs that a candid discussion of sunspots and their effects is due the general reader who would keep himself informed of trends in science. Sunspots have been blamed for calamities and misfortunes that run the gamut from Florida hurricanes to financial panics. Is there any basis whatever for such assumptions Since we are all more interested in ourselves than we are in things, the book has been written from the human point of view. While statements have been qualified, various possible hypotheses have been dis cussed which bear upon the question of solar dis turbances and affairs on the earth. Perhaps all too long has the reading public been dependent upon the technical material in textbooks on astronomy for a knowledge of sunspots. Such textbooks which must deal only with well-established facts cannot naturally try to discuss speculative questions. This book therefore departs from the usual type of book on science in that it frankly presents questionable material as well as the results of more completely Forewarning established facts from which the reader may draw his own conclusions with respect to inferences not yet fully established as weU as to those which may beregarded as beyond debate. As the book is intended to be distinctly popular, the more speculative material which intrigues the imagination has been presented in the earlier part, leaving the more well-established effects of sunspots upon the earth to the later chapters. The book undoubtedly raises more questions than it answers, and will, it is hoped, suggest attention to some of the less conventional aspects of the question concerning the influence of the sunspots on world events. So many apparently serious articles have been written concerning sunspots and the business cycle that a chapter is devoted to the more plausible hypoth eses that may be worth investigation If the author appears noncommittal in his interpretation of some of the more startling presentations, it is because a scientist cannot by nature be otherwise. On the other hand, I have refrained from condemning interpretations where evidence is still scanty, for thus to condemn appears to me as unscientific as to make positive statements where complete evidence is wanting. If the book falls into the hands of the overcredulous, perhaps a word of warning is necessary to curb hurried conclusions. One can only hope that none of the more speculative statements will be quoted except with qualifications which go therewith. Forewarning In the closing chapter I have endeavored to differ entiate clearly between the several effects well established and scientifically recognised from those which are more speculative and require much further investi gation before definite conclusions can be drawn. Only by such differentiation can the whole subject be clarified with the door still open for future progress. A scientific reader will misstechnical phraseology and numerous references quoting sources which obvi ously are out of place in so popular a presentation. If the reading of the book stimulates a consciousness of mans cosmic surroundings and opens certain ques tions for serious consideration, the answers to which are yet to come, the purpose of the book will in a meas ure be realized.

The sun is our local star; the most important object in our lives. But what really powers it? And who are the sun's favourite painters? Simon Barraclough is your guide in this tour-de-force book of poetry. Sunspots condenses fact, fiction, myth, humour and emotion into a luminous meditation on the star that gives us life.

Book Description
Planets, Sunspots and Earthquakes presents a working hypothesis of how planets trigger sunspots and earthquakes. Two distinct and separate effects are considered: one is an internal effect whereby the core of the sun and the earth become more active. The other is an external effect whereby the combined effect from external bodies stresses the earth's crust at a point where it enters or leaves the gravitational field of the group of external bodies.The causes of the initial internal processes that are necessary for the final seismic trigger effect to operate are examined and the connection with sunspot cycles is explored. The work is the result of observation and investigation during three eleven-year sunspot cycles, and offers material for further research by specialists and students.

Book Description
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.
