Magnetic fields permeate space and affect many major astrophysical phenomena, but they are often ignored due to their perceived complexity. This self-contained introduction to astrophysical magnetic fields provides both a comprehensive review of the current state of the subject and a critical discussion of the latest research. It presents our knowledge of magnetic fields from the Early Universe, their evolution in cosmic time through to their roles in present-day galaxies, galaxy clusters and the wider intergalactic medium, with attention given to both theory and observations. This volume also contains an extensive introduction into magnetohydrodynamics, numerous worked examples, observational and mathematical techniques and interpretations of the observations. Its review of our current knowledge, with an emphasis on results that are likely to form the basis for future progress, benefits a broad audience of advanced students and active researchers, including those from fields such as cosmology and general relativity.
Although the origin of Earth's and other celestial bodies' magnetic fields remains unknown, we do know that the motion of electrically conducting fluids generates and maintains these fields, forming the basis of magnetohydrodynamics (MHD) and, to a larger extent, dynamo theory. Answering the need for a comprehensive, interdisciplinary introduction
"The Diary" offers priceless documentation and guidance for an understanding of the rigidity that characterized the Bukharan Amirate throughout its tumultuous final decades of existence, ca. 1880-1920.
A long-overdue advancement in ceramic studies, this volume sheds new light on the adoption and dispersal of pottery by non-agricultural societies of prehistoric Eurasia. Major contributions from Western Europe, Eastern Europe and Asia make this a truly international work that brings together different theories and material for the first time. Researchers and scholars studying the origins and dispersal of pottery, the prehistoric peoples or Eurasia, and flow of ancient technologies will all benefit from this book.
While magnetic fields permeate the universe on all scales, the present book is dedicated to their investigation on the largest scales and affords a balanced account of both theoretical and observational aspects. Written as a set of advanced lectures and tutorial reviews that lead up to the forefront of research, this book offers both a modern source of reference for the experienced researchers as well as a high-level introductory text for postgraduate students and nonspecialist researchers working in related areas.
This book is about the importance of random phenomena occurring in nature. Cases are selected in which randomness is most important or crucial, such as Brownian motion, certain reactions in Physical Chemistry and Biology, and intermittency in magnetic field generation by turbulent fluid motion, etc. Due to ?almighty chance? the structures can originate from chaos even in linear problems. This idea is complementary as well as competes with a basic concept of synergetics where structures appear mainly due to the pan-linear nature of phenomena. This book takes a new look at the problem of structure formation in random media, qualitative physical representation of modern conceptions, intermittency, fractals, percolation and many examples from different fields of science.
This course-tested textbook conveys the fundamentals of magnetic fields and relativistic plasma in diffuse cosmic media, with a primary focus on phenomena that have been observed at different wavelengths. Theoretical concepts are addressed wherever necessary, with derivations presented in sufficient detail to be generally accessible. In the first few chapters the authors present an introduction to various astrophysical phenomena related to cosmic magnetism, with scales ranging from molecular clouds in star-forming regions and supernova remnants in the Milky Way, to clusters of galaxies. Later chapters address the role of magnetic fields in the evolution of the interstellar medium, galaxies and galaxy clusters. The book is intended for advanced undergraduate and postgraduate students in astronomy and physics and will serve as an entry point for those starting their first research projects in the field.
Sadr-i-Ziya's Diary lends valuable perspective to numerous studies narrowly focused upon the modern Reformists (Jadids) of his area. It also, and perhaps in the first place, reveals the endless occupational and mortal uncertainties tormenting a Central Asian Islamic judge practicing his profession within an aged political and economical system deteriorating during the last decades, ca. 1880-1920, of the state of Bukhara. By supplying a Bukharan intellectual's personal history, Sadr-i Ziya, author, poet and calligrapher, also reveals himself as an admirable human being who enjoys life but endures the repeated, scalding experience of losing beloved children, their mothers, and other family members, in an era when medicine and prayer scarcely deterred the multitude of prevailing inflictions. Nothwithstanding this strong focus upon his personal life, Sadr-i Ziya provides an unparalleled view of the central role played by the omnipresent religious hierarchy in his homeland.
