Interaction of Radiation with Matter
Interaction of Radiation with Matter focuses on the physics of the interactions of ionizing radiation in living matter and the Monte Carlo simulation of radiation tracks. Clearly progressing from an elementary level to the state of the art, the text explores the classical physics of track description as well as modern aspects based on condensed matter physics. The first section of the book discusses the fundamentals of the radiation field. In the second section, the authors describe the cross sections for electrons and heavy ions--the most important information needed for simulating radiation track at the molecular level. The third section details the inelastic scattering and energy loss of charged particles in condensed media, particularly liquid water. The final section contains a large number of questions and problems to reinforce learning. Designed for radiation interaction courses, this textbook is the ideal platform for teaching students in medical/health physics and nuclear engineering. It gives students a solid grounding in the physical understanding of radiation track structure in living matter, enabling them to pursue further work in radiological physics and radiation dosimetry.

The Ghost in the Telescope
The Ghost in the Telescope is an insider's account of the Herschel Space Observatory, which was launched to answer two of the biggest questions in astronomy: How were the stars and galaxies born?Written in an engaging manner for a general audience, this book tells the stories of the telescope itself, the discoveries it made, and the engineers and astronomers who built and used it.This book, based on the author's own experience and interviews with the key astronomers and engineers, tells the story of the mission, from its original concept on a piece of paper in Venice to the moment after the end of the mission when the engineers had to decide whether to crash the spacecraft into the Moon. Containing some of the most spectacular pictures ever taken of the universe, this book describes all the major discoveries made with the telescope. It also gives an account, accessible to anyone without previous scientific knowledge, of the latest research into the births of stars and galaxies.This book may interest anyone who is curious about astronomy, space missions, and how astronomy is done in practice. It is designed to be easy to read and does not require any previous scientific background.
Non-Self-Adjoint Schr繹dinger Operator with a Periodic Potential
This book offers a comprehensive exploration of spectral theory for non-self-adjoint differential operators with complex-valued periodic coefficients, addressing one of the most challenging problems in mathematical physics and quantum mechanics: constructing spectral expansions in the absence of a general spectral theorem. It examines scalar and vector Schr繹dinger operators, including those with PT-symmetric periodic optical potentials, and extends these methodologies to higher-order operators with periodic matrix coefficients. The second edition significantly expands upon the first by introducing two new chapters that provide a complete description of the spectral theory of non-self-adjoint differential operators with periodic coefficients. The first of these new chapters focuses on the vector case, offering a detailed analysis of the spectral theory of non-self-adjoint Schr繹dinger operators with periodic matrix potentials. It thoroughly examines eigenvalues, eigenfunctions, and spectral expansions for systems of one-dimensional Schr繹dinger operators. The second chapter develops a comprehensive spectral theory for all ordinary differential operators, including higher-order and vector cases, with periodic coefficients. It also includes a complete classification of the spectrum for PT-symmetric periodic differential operators, making this edition the most comprehensive treatment of these topics to date. The book begins with foundational topics, including spectral theory for Schr繹dinger operators with complex-valued periodic potentials, and systematically advances to specialized cases such as the Mathieu-Schr繹dinger operator and PT-symmetric periodic systems. By progressively increasing the complexity, it provides a unified and accessible framework for students and researchers. The approaches developed here open new horizons for spectral analysis, particularly in the context of optics, quantum mechanics, and mathematical physics.

Enhancing Citizens' Role in Public Safety
The COVID-19 pandemic and the war in Ukraine emphasize the need for greater disaster resilience and preparedness. This book investigates how these apps can enhance crisis awareness and citizen involvement in disaster prevention and response. By examining user perspectives and the impact of crisis experiences, the book explores how to increase the adoption and effectiveness of warning apps. The research uses qualitative and quantitative methods, including surveys and design interventions, to reveal current usage, changes over time and desired features. It shows that while citizens find warning apps helpful, more safety-related features and two-way communication could increase their appeal. Additionally, the integration of preparedness features into these apps can increase their perceived usefulness, though challenges remain in addressing user expectations and design preferences across different crises and cultural contexts.

Back to the Moon
A scientist's inspiring vision of our return to the Moon as humanity's next thrilling step in space exploration Just over half a century since Neil Armstrong first stepped foot on the lunar surface, a new space race to the Moon is well underway and rapidly gaining momentum. Laying out a vision for the next fifty years, Back to the Moon is astrophysicist Joseph Silk's persuasive and impassioned case for putting scientific discovery at the forefront of lunar exploration. The Moon offers opportunities beyond our wildest imaginings, and plans to return are rapidly gaining momentum around the world. NASA aims to build a habitable orbiting space station to coordinate lunar development and exploration, while European and Chinese space agencies are planning lunar villages and the mining of precious resources dwindling here on Earth. Powerful international and commercial interests are driving the race to revisit the Moon, but lunar infrastructures could also open breathtaking vistas onto the cosmos. Silk describes how the colonization of the Moon could usher in a thrilling new age of scientific exploration, and lays out what the next fifty years of lunar science might look like. With lunar telescopes of unprecedented size situated in permanently dark polar craters and on the far side of the Moon, we could finally be poised to answer some of the most profound questions confronting humankind, including whether we are alone in the Universe and what our cosmic origins are. Addressing both the daunting challenges and the immense promise of lunar exploration and exploitation, Back to the Moon reveals how prioritizing science, and in particular lunar astronomy, will enable us to address the deepest cosmic mysteries.

Langevin Stochastic Equations: Treatment of Ocean, Planetary Boundary Layer, and Stellar Turbulence
This book derives, solves, and assesses the Langevin Stochastic Equations (LSE) as a tool for treating turbulent flows. Previous work has demonstrated the LSE's ability to successfully describe non-geophysical turbulent flows. However, this book specifically focuses on geophysical flows. Chapter I addresses the modeling of oceanic mesoscales (M) and sub-mesoscales (SM), while Chapter II discusses vertical mixing. The target audience for this book is advanced students and researchers interested in future climate change and the crucial role played by the ocean. One of the main challenges in describing oceanic M and SM is that they are governed by non-linear interactions for which no satisfactory model exists. Despite the unsuccessful attempts to describe non-linearity using the traditional Navier-Stokes Equations (NSE), heuristic models continue to be used. This has created a dilemma: while future climate projections need to be predictive, the heuristic treatment of M and SM lacks predictive power, leading to an internal inconsistency. The primary goal of this book is to demonstrate that the transition from NSE to LSE resolves this inconsistency, paving the way for a fully predictive treatment of M and SM. This advancement is crucial for providing future climate predictions with the credibility they require.
