Go on an awe-inspiring journey, unraveling the secrets of our universe from the tiniest particles to the vastness of space In this thought-provoking exploration, physicists Chris Ferrie and Geraint F.Lewis delve into the fundamental questions that have puzzled humanity for centuries.What sparked the birth of the universe?.

This book is a thorough and up‐to‐date introduction to black hole physics. It provides a modern and unified overview of all their aspects, physical, mathematical, astrophysical, classical, and quantum. Black holes are the most intriguing objects in the Universe. For many years they have been considered just as interesting solutions of the General Relativity with a number of amusing mathematical properties. But now, after discovery of astrophysical black holes, the Einstein gravity has become a practical tool for their study. In this book we present the theory of black holes in the form which might be useful for students and young scientists. This is a self‐contained textbook. It includes pedagogically presented `standard' material on black holes and also quite new subjects such as black holes in spacetimes with large extra dimensions and a role of hidden symmetries in black hole physics.

This book is a historical account of how natural philosophers and scientists have endeavoured to understand the universe at large, first in a mythical and later in a scientific context. Starting with the creation stories of ancient Egypt and Mesopotamia, the book covers all the major events in theoretical and observational cosmology, from Aristotle's cosmos over the Copernican revolution to the discovery of the accelerating universe in the late 1990s. The kind of cosmology it describes and analyses focuses on the physical and astronomical aspects, but these cannot always be separated from aspects of a philosophical and theological nature. The book presents cosmology as a subject including scientific as well as non-scientific dimensions, and tells the story of how it developed into a true science of the heavens. Contrary to most other books on the history of cosmology, it offers an integrated account of the development with emphasis on the modern Einsteinian and post-Einsteinian period. In addition, it pays attention not only to mainstream developments, but also to theories of the universe that are today considered to be blind alleys. Starting in the pre-literary era, the book carries the story of mankind's quest of understanding the universe onwards to the early years of the 21st century.

This book introduces Einstein’s general theory of relativity. Topics include the geometric formulation of special relativity, the principle of equivalence, the Einstein field equation and its spherical solution, and black holes, as well as cosmology. The subject is presented with an emphasis on physical examples and simple applications without the full tensor apparatus (although, for those wishing to have a glimpse at the proper tensor formulation of Einstein’s field equation, this is presented in a final chapter). The reader first learns the physics of the equivalence principle and how it inspired Einstein’s idea of curved spacetime as the gravitational field. At the mathematically more accessible level of a metric description of a warped space, the reader can already study many interesting phenomena, such as gravitational time dilation, GPS operation, light deflection, precession of Mercury’s perihelion, and black holes. Many modern topics in cosmology are discussed: from primordial inflation and the cosmic microwave background, to the dark energy that propels an accelerating universe.

A bstract A light singlet scalar field feebly coupled through the super-renormalizable Higgs portal provides a minimal and well-motivated realization of ultra-light bosonic dark matter. We study the cosmological production of dark matter in this model by elucidating the dynamics of two sources of scalar field misalignment generated during the radiation era. For large scalar masses (above O (10 − 3 eV)), dark matter is produced through thermal misalignment , by which the scalar field is driven towards large field values as a result of the finite-temperature effective potential. The dominance of thermal misalignment in this mass range leads to a sharp relic abundance prediction which is, to a significant extent, insensitive to the initial conditions of the scalar field. On the other hand, for low mass scalars (below O (10 − 5 eV)), dark matter is produced via VEV misalignment , which is caused by the induced scalar field vacuum expectation value triggered by the electroweak phase transition. We show that the relic abundance in this low mass range is sensitive to the scalar field initial conditions. In the intermediate mass range, the relic abundance is a consequence of a competition between thermal misalignment and VEV misalignment, which can potentially lead to novel forced resonance effects which cause a recurring enhancement and suppression in the late time oscillation amplitude as a function of the scalar mass. We compare our relic abundance predictions with constraints and projections from equivalence principle and inverse square law tests, stellar cooling, resonant molecular absorption, and observations of extra-galactic background light and diffuse X-ray backgrounds. New experimental ideas are needed to probe most of the cosmologically motivated regions of parameter space.

This book presents previously unexamined connections between teaching practices and specific philosophical ideas, locating the prior beliefs and practical knowledge of early childhood practitioners in urban India within the broader social and historical religio-philosophical context.

Drawing on indigenous belief systems and recent work in critical 'race' studies and multicultural-feminist theory, Keating provides detailed step-by-step suggestions, based on her own teaching experiences, designed to anticipate and change students' resistance to social-justice issues. It offers a holistic approach to theory and practice.

This collection includes original studies from scholars from thirteen nations, who explore the epistemic features figured in John Dewey's writings in his discourses on public schooling. Pragmatism was one of the weapons used in the struggles about the development of the child who becomes the future citizen. The significance of Dewey in the book is not about Dewey as the messenger of pragmatism, but in locating different cultural, political and educational terrains in which debates about modernity, the modern self and the making of the citizen occurred.

An introduction to Vodou practices and beliefs, with a focus on Haiti.

This collection on peace education includes contributions from an international group of scholars representing a wide variety of geographical conflict areas and exemplifying the multiple venues of peace educational labour. A strong emphasis is given to integrative and sustained long-term peace education efforts.
