Physics and Astronomy: Books

Helicities in Geophysics, Astrophysics, and Beyond

This volume explores the concept of helicity—defined by the volume integral of the inner product of a vector field and its curl—and its critical role in a wide range of plasma and astrophysical phenomena. These include stellar and planetary dynamos, star formation, accretion jets, magnetic field amplification, and magnetic confinement in fusion research. Recognising its significance across disciplines, the book presents diverse perspectives and approaches to the study of helicity in both theoretical and applied contexts. (Provided by Publisher.)

Planet Earth, Past and Present: Parallels Between Our World and Its Celestial Neighbors

The Earth is not the world it once was, and it is not the world it will always be. This book describes the exciting, complex, and occasionally baffling history of our own planet. Over the course of its 4.5 billion years, Earth has undergone astonishing changes to its surface and atmosphere, at times more closely resembling other planets in our Solar System than the habitable, teeming biosphere of today. Through these otherworldly analogs, author-illustrator Michael Carroll teaches readers about different aspects of our own planet's past. Our nearest cosmic neighbor, Venus, offers insights into Earth's own young atmosphere and surface, while Saturn's moon Titan may offer a window into the genesis of life on Earth. Planet Earth, Past and Present explores these and many more connections. Original art accompanies each chapter, depicting major stages of the Earth's evolution and providing vivid comparisons to other planets or moons. Come along on this journey through the Solar System-a journey that ultimately leads us home (Provided by Publisher).

Electromagnetic Sources and Electromagnetic Fields

This book presents a modified spherical harmonic expansion method in which the electromagnetic fields and their sources are expanded with the same set of spherical vector basis functions in a similar procedure. Explicit expressions for the electromagnetic fields, potentials, energies, and the related Green’s functions are derived for the spherical modes in both frequency domain and time domain. Based on the formulation, the relationships between the electromagnetic sources, the electromagnetic far fields, and the electromagnetic near fields are clearly revealed. In particular, a nonuniform transmission line model is developed for intuitively characterizing the total radiation process. The introduction of the cutoff radius and the cutoff mode degree provides a simple reference for determining the numbers of degrees of freedom of the fields associated with sources in a bounded region. Based on the theory, an efficient hybrid method for synthesizing antenna arrays with complex footprints is proposed and demonstrated with several numerical examples. Effective algorithms are also developed for reconstructing the radiating part of the current sources.

This book is intended for researchers, engineers, and graduate students who are interested in studying the energy transfer in electromagnetic radiation, synthesis and measurement of antenna arrays, and applications of inverse electromagnetic source problems (Provided by Publisher)

Women and Physics, Second Edition

This is the second edition of a volume that brings together research on a wide variety of topics relating to gender and physics, cataloguing the extant literature to provide a readable and concise grounding for the reader. While there are many biographies and collections of essays in the area of women and physics, no other book is as research focused. Starting with the current numbers of women in physics in English-speaking countries, it explores the different issues relating to gender and physics at different educational levels and career stages. From the effects of family and schooling to the barriers faced in the workplace and at home, this volume is an exhaustive overview of the many studies focused specifically on women and physics. This edition contains updated references and new chapters covering the underlying structures of the research and more detailed breakdowns of career issues. (Provided by Publisher.)
