This book introduces young researchers to the exciting field of ultra-high energy astrophysics including charged particles, gamma rays and neutrinos. At ultra-high energy the radiation is produced by interactions of cosmic ray particles accelerated in explosive events such as supernovae or hypernovae, black holes or, possibly, the big bang. Through direct contact with senior scientists, now actively planning the next generation of experiments/models, the excitement and motivation for research at ultra-high energy was conveyed. The underpinning of these fields is a synthesis of knowledge and techniques from nuclear and particle physics, astronomy and cosmology. Informing the participants of t...
This is an excellent reference for atmospheric scientists, policy makers, environmental managers, and environmental consultants. Topics covered include acid rain, greenhouse gases, stratospheric ozone, and the air chemistry of various materials - from their emission into the atmosphere to their removal. CONTENTS: Introduction: Past Changes in Atmospheric Environment. Present Variations of the Atmospheric Concentrations and Emissions of Trace Substances. Formation and Destruction of Trace Substances within the Atmosphere. Removal of Trace Substances from the Atmosphere. Atmospheric Cycles and Their Changes. Environmental Consequences of Anthropogenic Modifications: The Future of the Atmosphere. Index.
A complete text on the physics of gamma-ray bursts, the most brilliant explosions since the Big Bang.
The existence of materials with very high specific energies greatly exceeding the local virial temperature is best represented by cosmic rays, whose origin has long been a mystery. Recent astrophysical observations in X-ray, gamma-ray, neutrino, and high energy cosmic ray experiments, in conjunction with theoretical studies, have revealed various new aspects of the high energy universe, including promising candidates for cosmic ray acceleration sites. As each approach has its own advantages and limitations, it is expected that joint efforts by experimentalists and theorists in various related fields are essential. The contributions in this volume include observation of the universe through a wide range of techniques for detecting cosmic rays, neutrinos, X-rays and gamma-rays, as well as theoretical considerations in understanding their nature and astrophysical aspects.
Since the dawn of mankind, observers of the sky have wondered at the sudden appearance of new stars on the seemingly unchanging heavens and, for at least 2000 years, have recorded these phenomena in their annals and archives. Even in more modern times, since the discovery of SN1885A in S Andromeda which ?gured in the important “island universe” discussions of the 1920’s, the puzzle of supernovae (SNe) has played an important role in astrophysics. Only with the seminal work of Fritz Zwicky and Walter Baade in the 1930’s did we begin to understand the di?erences between novae and SNe and the importance of SNe as the fonts of energy for the interstellar medium and as drivers of chemical...
This book demonstrates that the cooperative model is based on principles essential to building a more just and democratic society. It is argued that this is the best economic reform alternative to neoliberal capitalism and authoritarian socialism in Cuba, and that this model can also radically transform other economies around the world.
Explore spectacular advances in contemporary physics with this unique celebration of the centennial of Einstein's discovery of general relativity.
The debate on “sustainable development”, ecosocialism, agroecology and the production of healthy food is increasing in Europe and in the world. This book depicts peasants' struggles for the resistance to the advance of destructive production. It also socializes the results of research, which shows us the pressage of alternative forms of labour, which are based upon agroecology, in cooperation and corporativism besides the emergence of agroecology schools of one of the main social movements of the present time: the Landless Movement.
A Global Warming Forum: Scientific, Economic, and Legal Overview provides an integrated, thematic approach to major critical aspects of the problem presented by global warming. Scientific issues; economics; natural resource management concerns; and legal, educational, and policy considerations are discussed within the context of arriving at solutions to global warming problems. Data and information is derived from diverse geographic locations, especially in the case history chapters requiring the use of integrated interdisciplinary methods. Graphs and tables are used extensively throughout the text to illustrate key concepts. A Global Warming Forum: Scientific, Economic, and Legal Overview is an excellent survey for researchers in all areas of geoscience and climate assessment, including geochemistry, oceanography, climatology, and resource management.
