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.

The marriage of philosophy and fiction in the first third of Spain's twentieth century was a fertile one. It produced some truly notable offspring -- novels that cross genre boundaries to find innovative forms, and treatises that fuse literature and philosophy in new ways. In her illuminating interdisciplinary study of Spanish fiction of the "Silver Age," Roberta Johnson places this important body of Spanish literature in context through a synthesis of social, literary, and philosophical history. Her examination of the work of Miguel de Unamuno, Pio Baroja, Azorin, Ramon Perez de Ayala, Juan Ramon Jimenez, Gabriel Miro, Pedro Salinas, Rosa Chacel, and Benjamin Jarnes brings to light philosophical frictions and debates and opens new interpersonal and intertextual perspectives on many of the period's most canonical novels. Johnson reformulates the traditional discussion of generations and "isms" by viewing the period as an intergenerational complex in which writers with similar philosophical and personal interests constituted dynamic groupings that interacted and constantly defined and redefined one another. Current narratological theories, including those of Todorov, Genette, Bakhtin, and Martinez Bonati, assist in teasing out the intertextual maneuvers and philosophical conflicts embedded in the novels of the period, while the sociological and biographical material bridges the philosophical and literary analyses. The result, solidly grounded in original archival research, is a convincingly complete picture of Spain's intellectual world in the first thirty years of this century. Crossfire should revolutionize thinking about the Generation of '98 and the Generation of '14 by identifying the heterogeneous philosophical sources of each and the writers' reactions to them in fiction.

? J. Andersen Niels Bohr Institute for Astronomy Physics and Geophysics Astronomical Observatory Copenhagen [email protected] The development of astronomy worldwide begins at the roots: Already from childhood, humans of all nations and civilizations seem to share an innate fascination with the sky. Yet, people in different regions of the world have vastly different possibilities for pursuing this interest. In wealthy, industrialised societies the way is open to a school or higher education in science, possibly leading to a career in astronomy or basic or applied space science for the benefit of the country as well as the individual. In other regions, neither the financial nor the trained human resources are sufficient to offer that avenue to the future of the young generation, or those intellectual resources to the development of their country. This book addresses ways and means by which these obstacles can be, if not fully overcome, then at least significantly reduced.

A unique approach to quantum field theory, with emphasis on the principles of renormalization Quantum field theory is frequently approached from the perspective of particle physics. This book adopts a more general point of view and includes applications of condensed matter physics. Written by a highly respected writer and researcher, it first develops traditional concepts, including Feynman graphs, before moving on to key topics such as functional integrals, statistical mechanics, and Wilson's renormalization group. The connection between the latter and conventional perturbative renormalization is explained. Quantum Field Theory is an exceptional textbook for graduate students familiar with advanced quantum mechanics as well as physicists with an interest in theoretical physics. It features: * Coverage of quantum electrodynamics with practical calculations and a discussion of perturbative renormalization * A discussion of the Feynman path integrals and a host of current subjects, including the physical approach to renormalization, spontaneous symmetry breaking and superfluidity, and topological excitations * Nineteen self-contained chapters with exercises, supplemented with graphs and charts

"The first exhibition to offer a critical assessment of the artistic experimentation that took place in Mexico during the last three decades of the twentieth century. The exhibition carefully analyzes the origins and emergence of techniques, strategies, andmodes of operation at a particularly significant moment of Mexican history, beginning with the 1968 Student Movement, until the Zapatista upraising in the State of Chiapas. Theshow includes work by a wide range of artists, including Francis Alys, Vicente Rojo, Jimmie Durham, Helen Escobedo, Julio Galán, Felipe Ehrenberg, José Bedia,Guillermo Gómez-Peña, Francisco Toledo, Carlos Amorales, Melanie Smith, and Alejandro Jodorowsky, among many others. The edition is illustrated with 612 full-colorplates of the art produced during these last three decades of the twentieth century reflect the social, political and technical developments in Mexico and ranged from painting andphotography to poster design, installation, performance, experimental theatre, super-8 cinema, video, music, poetry and popular culture like the films and ephemeral actionsof 'Panic' by Alejandro Jodorowsky, Pedro Friedeberg's pop art, the conceptual art, infrarrealists and urban independent photography, artists books, the development ofcontemporary political photography, the participation of Mexican artists in Fluxus in the seventies and the contribution of Ulises Carrión to the international artist book movement and popular rock music, the pictorial battles of the eighties and the emergence of a variant of neo-conceptual art in 1990. The exhibition is curated by Olivier Debroise, Pilar García de Germenos, Cuauhtémoc Medina, Álvaro Vázquez Mantecón"--Provided by vendor.

Black holes may obliterate most things that come near them, but they saved the theory of general relativity. Einstein's theory was quickly accepted as the true theory of gravity after its publication in 1915, but soon took a back seat in physics to quantum mechanics and languished for decades on the blackboards of mathematicians. Not until the existence of black holes by Stephen Hawking and Roger Penrose in the 1960s, after Einstein's death, was the theory revived. Almost one hundred years after general relativity replaced Newton's theory of gravitation, The Curious History of Relativity tells the story of both events surrounding general relativity and the techniques employed by Einstein and the relativists to construct, develop, and understand his almost impenetrable theory. Jean Eisenstaedt, one of the world's leading experts on the subject, also discusses the theory's place in the evolution of twentieth-century physics. He describes the main stages in the development of general relativity: its beginnings, its strange crossing of the desert during Einstein's lifetime while under heated criticism, and its new life from the 1960s on, when it became vital to the understanding of black holes and the observation of exotic objects, and, eventually, to the discovery of the accelerating universe. We witness Einstein's construction of his theory, as well as the work of his fascinated, discouraged, and enthusiastic colleagues--physicists, mathematicians, and astronomers. Written with flair, The Curious History of Relativity poses--and answers--the difficult questions raised by Einstein's magnificent intellectual feat.
