Quantum cosmology has gradually emerged as the focus of devoted research, mostly within the second half of last century. As we entered the 21st century, the subject is still very much alive. The outcome of results and templates for investigation have been enlarged, some very recent and fascinating. Hence this book, where the authors bequeath some of their views, as they believe this current century is the one where quantum cosmology will be fully accomplished. Though some aspects are not discussed (namely, supersymmetry or loop structures), there are perhaps a set of challenges that in the authors' opinion remain, some since the dawn of quantum mechanics and applications to cosmology.

In The First Atomic Bomb Janet Farrell Brodie explores the history of the Trinity test and those whose contributions have rarely, if ever, been discussed--the men and women who constructed, served, and witnessed the first test--as well as the downwinders who suffered the consequences of the radiation. Concentrating on these ordinary people, laborers, ranchers, and Indigenous peoples who lived in the region and participated in the testing, Brodie corrects the lack of coverage in existing scholarship on the essential details and everyday experiences of this globally significant event. The First Atomic Bomb also covers the environmental preservation of the Trinity test site and compares it with the wide range of atomic sites now preserved independently or as part of the new Manhattan Project National Historical Park.

The book provides a self-contained and accessible introduction to integrability of ordinary and partial differential equations. It explores symmetry analysis, gauge theory, vortices, gravitational instantons, twistor transforms, anti-self-duality equations, basic differential geometry, complex manifold theory, and the exterior differential system.

In Galaxies, Or Graur offers a brief and fascinating overview of the history, physics, and astrophysical uses of galaxies. Starting with the history of the last two thousand years of galaxy studies, Graur discusses the types of galaxies we observe and the physics that drive them; the myths and physical structure of the Milky Way; how galaxies were used to discover and study the mysterious phenomena of dark matter and dark energy; and how scientists think galaxies formed shortly after the Big Bang and evolved to their present forms.

Beginning with an introduction to the basics of radiation, the book then covers its application in medical diagnostics, cancer treatment, the improvement of agriculture yield, the eradication of pests, and food preservation, its use in non-destructive examination and material characterisation, security devices, its industrial applications in general, and in the petroleum industry and wastewater treatment. It presents a comparison of nuclear with other energy sources from different angles, bringing out the fact that nuclear power has minimal environmental and health effects.

Photographic Atlas of the Moon explains how the Earth and the Moon are locked together in a co-dependent embrace, each affecting the other in ways that affect our lives on this planet. The reader will learn in an understandable jargon-free narrative the differing geologic details of the Moon, some of which can be seen with the naked eye, allowing an appreciation of the diversity of lunar landforms.
