Combining research methods from various areas of mathematics and physics, Probabilistic Models of Cosmic Backgrounds describes the isotropic random sections of certain fiber bundles and their applications to creating rigorous mathematical models of both discovered and hypothetical cosmic backgrounds. Previously scattered and hard-to-find mathematical and physical theories have been assembled from numerous textbooks, monographs, and research papers, and explained from different or even unexpected points of view. This consists of both classical and newly discovered results necessary for understanding a sophisticated problem of modelling cosmic backgrounds. The book contains a comprehensive description of mathematical and physical aspects of cosmic backgrounds with a clear focus on examples and explicit calculations. Its reader will bridge the gap of misunderstanding between the specialists in various theoretical and applied areas who speak different scientific languages. The audience of the book consists of scholars, students, and professional researchers. A scholar will find basic material for starting their own research. A student will use the book as supplementary material for various courses and modules. A professional mathematician will find a description of several physical phenomena at the rigorous mathematical level. A professional physicist will discover mathematical foundations for well-known physical theories.

This book reflects on 8 decades of research on one of the longest-standing unsolved problems in modern astrophysics: why does the Sun form a hot corona? The authors give a critical overview of the field and offer suggestions on how to bridge the chasm between what we can measure, and what we can calculate. They go back to basics to explain why the problem is difficult, where we have made progress and where we have not, to help the next generation of scientists devise novel techniques to crack such a long-lasting problem. A way forward is formulated centered around refutation, using Bayesian methods to propose and to try to reject hypotheses and models, and avoiding seduction by ``confirmation bias''. This book is aimed at physicists, students and researchers interested in understanding, learning from and solving the coronal heating problem, in an era of new dedicated facilities such as the Parker Solar Probe and the Daniel K. Inouye Solar Telescope.    Thebook will appeal to those interested in understanding research methods and how they are changing in the modern academic environment, particular in astrophysics and Earth sciences where remote sensing is essential.

 The book presents seven fundamental concepts in spacetime physics mostly by following Hermann Minkowski's revolutionary ideas summarized in his 1908 lecture "Space and Time." These concepts are:  spacetime, inertial and accelerated motion in spacetime physics, the origin and nature of inertia in spacetime physics, relativistic mass, gravitation, gravitational waves, and black holes. They have been selected because they appear to be causing most misconceptions and confusion in spacetime physics. This second edition has been revised to include additional clarifications, more detailed elaboration of the arguments and also new material published in the interim.

This textbook, based on the author's classroom-tested lecture course, helps graduate students master the advanced plasma theory needed to unlock results at the forefront of current research. It is structured around a two semester course, beginning with kinetic theory and transport processes, while the second semester is devoted to plasma dynamics, including MHD theory, equilibrium, and stability. More advanced problems such as neoclassical theory, stochastization of the magnetic field lines, and edge plasma physics are also considered, and each chapter ends with an illustrative example which demonstrates a concrete application of the theory. The distinctive feature of this book is that, unlike most other advanced plasma science texts, phenomena in both low and high temperature plasma are considered simultaneously so that theory of slightly ionized and fully ionized plasmas is presented holistically. This book will therefore be ideal as a classroom text or self-study guide for a widecohort of graduate students working in different areas like nuclear fusion, gas discharge physics, low temperature plasma applications, astrophysics, and more. It is also a useful reference for more seasoned researchers.

The present monograph brings to readers, as researchers and students of physics and mathematics, recent developments in symmetries, where the representation space is a symplectic manifold. This gives rise to the quantum field theory formulated in through the concept of phase space and associated with the Wigner function, a quasi-distribution of probability. This approach provides information about non-classicality of quantum systems, describes quantum chaos and is the starting point of the quantum kinetic theory. In this realm, abelian and non-abelian gauge symmetries are introduced with the concept of quasi-amplitude of probability. This leads, for instance, to Symplectic Schrödinger, Klein-Gordon and Dirac equations dealing with systems in condensed matter and particle physics. These achievements are depicted here, following a pedagogical model of presentation.

This book presents and details the process of quantization of a classical mechanical system in a relevant physical system, the harmonic oscillator.  In quantum field theory or general relativity, mathematics and physics are inextricably interwoven.  As such, the book is mathematically rigorous.  The author focuses on the properties of the quantum system that can be observed and measured and interprets the resulting theory.  The methods of operator theory are discussed throughout in the formulation of the theory as well as in the calculation of the consequences of the theory.  The book addresses the mathematical support of the probabilistic interpretation of quantum mechanics through the spectral theorems for (densely-defined and linear) self-adjoint operators in Hilbert spaces.  Considerable focus is placed on the measurement process and questions the challenges of the wave function, the EPR paradox, and Bell's inequality. 

An exciting new title in the vein of Hidden Figures, which tells the inspiring stories of long-overlooked women physicists and astronomers who discovered the fundamental rules of the universe and reshaped the rules of society. Women physicists and astronomers from around the world have transformed science and society, but the critical roles they played in their fields are not always well-sung. Her Space, Her Time, authored by award-winning quantum physicist Shohini Ghose, brings together the stories of these remarkable women to celebrate their indelible scientific contributions. In each chapter of the book, Ghose explores a scientific topic and explains how the women featured in that chapter revolutionized that area of physics and astronomy. In doing so, she also addresses particular aspects of women's experiences in physics and astronomy- in the chapter on time, for instance, we learn of Henrietta Leavitt andMargaret Burbidge, who helped discover the big bang and the cosmic calendar; in the chapter on space exploration, we learn of Anigaduwagi (Cherokee) aerospace scientist Mary Golda Ross,who helped make the Moon landings possible; and in the chapter on subatomic particles, we learn of Marietta Blau, Hertha Wambacher, and Bibha Chowdhuri, who contributed to the discovery of the building blocks of the universe, and, in doing so, played a crucial role in determining who gets to do physics today. Engaging, accessible, and timely, Her Space, Her Time is a collective story of scientific innovation, inspirational leadership, and overcoming invisibility that will leave a lasting impression on any reader curious about the rule-breakers and trendsetters who illuminated our understanding of the universe.

"This is a delightful account of one of the deepest and most fascinating explorations going on today at the frontier of our knowledge." --Carlo Rovelli, bestselling author of The Order of Time and Seven Brief Lessons on Physics "Musser knows that the point of popular science is [. . .] to get a sense of what's at stake, what kinds of answers are being offered to difficult questions, and why it all matters. One could not ask more of Putting Ourselves Back in the Equation--on all three counts it delivers." --Julian Baggini, The Wall Street Journal A revelatory exploration of how a "theory of everything" depends upon our understanding of the human mind. The whole goal of physics is to explain what we observe. For centuries, physicists believed that observations yielded faithful representations of what is out there. But when they began to study the subatomic realm, they found that observation often interferes with what is being observed--that the act of seeing changes what we see. The same is true of cosmology: our view of the universe is inevitably distorted by observation bias. And so whether they're studying subatomic particles or galaxies, physicists must first explain consciousness--and for that they must turn to neuroscientists and philosophers of mind. Neuroscientists have painstakingly built up an understanding of the structure of the brain. Could this help physicists understand the levels of self-organization they observe in other systems? These same physicists, meanwhile, are trying to explain how particles organize themselves into the objects around us. Could their discoveries help explain how neurons produce our conscious experience? Exploring these questions and more, George Musser tackles the extraordinary interconnections between quantum mechanics, cosmology, human consciousness, and artificial intelligence. Combining vivid descriptive writing with portraits of scientists working on the cutting edge, Putting Ourselves Back in the Equation shows how theories of everything depend on theories of mind--and how they might be one and the same.
