In September 2017, the Cassini spacecraft will point itself toward the atmoshpere of Saturn and end its 13-year mission of solving many of the mysteries of the ringed planet's system with a crash. This book is a dramatic, beautifully illustrated journey of discovery through the Saturn system. Cassini's instruments have revealed never seen before details including the only extraterrestrial lakes known in the solar system and have provided unprecedented views of the rings. It is a non-technical book for everyone who loves astronomy.
Adolescent brain development is a fascinating, newly developing field that has so much to offer almost anyone interested in learning more. In this book, the authors compare adolescent behavioural changes with ongoing changes in the brain and discuss potential implications for health and educational policy-making.
Describes in detail what is known about the electrostatic environment of the solar system from early and current experiments on Earth as well as what is being learned from the instrumentation on the space exploration missions (NASA, European Space Agency, and the Japanese Space Agency) of the last few decades. It begins with a brief review of the basic principles of electrostatics.
This book is written for students and other interested readers as a look inside the diverse range of applications for physics outside of the scientific research environment. This first volume covers several different areas of the arts and design ranging from stage lighting to sculpting. The author has interviewed experts in each area to explain how physics and technology impact their work. These are all useful examples of how physics encountered in taught courses relates to the real world.
This book provides a broad introductory survey of this remarkable field, aiming to establish and clearly differentiate its physical principles, and also to provide a snapshot portrait of many of the most prominent current applications. Primary emphasis is placed on developing an understanding of the fundamental photonic origin behind the mechanism that operates in each type of effect. To this end, the first few chapters introduce and develop core theory, focusing on the physical significance and source of the most salient parameters, and revealing the detailed interplay between the key material and optical properties. Where appropriate, both classical and photonic (quantum mechanical) representations are discussed. The number of equations is purposely kept to a minimum, and only a broad background in optical physics is assumed.With copious examples and illustrations, each of the subsequent chapters then sets out to explain and exhibit the main features and uses of the various distinct types of mechanism that can be involved in optical nanomanipulation, including some of the very latest developments. To complete the scene, we also briefly discuss applications to larger, biological particles. Overall, this book aims to deliver to the non-specialist an amenable introduction to the technically more advanced literature on individual manipulation methods. Full references to the original research papers are given throughout, and an up-to-date bibliography is provided for each chapter, which directs the reader to other selected, more specialised sources.

This is your guide to fundamental principles, providing intuitive, basic explanations for the bicycle's behaviour.
What does it take to consider a planet potentially habitable? If a planet is suitable for life, could life be present? Is life on other planets inevitable? Searching for Habitable Worlds answers these questions and provides both the general public and astronomy enthusiasts with a richly illustrated discussion of the most current knowledge regarding the search for extrasolar planets.
Provides a rigorous macroscopic description of the interaction between electromagnetic radiation and structures containing graphene sheets (two-dimensional structures). It presents canonical problems with translational invariant geometries, in which the solution of the original vectorial problem can be reduced to the treatment of two scalar problems, corresponding to two basic polarization modes.
Searching for Dark Matter with Cosmic Gamma Rays summarizes the evidence for dark matter and what we can learn about its particle nature using cosmic gamma rays. It has almost been 100 years since Fritz Zwicky first detected hints that most of the matter in the Universe that doesn't directly emit or reflect light. Since then, the observational evidence for dark matter has continued to grow. Dark matter may be a new kind of particle that is governed by physics beyond our Standard Model of particle physics. In many models, dark matter annihilation or decay produces gamma rays. There are a variety of instruments observing the gamma-ray sky from tens of MeV to hundreds of TeV. Some make deep, focused observations of small regions, while others provide coverage of the entire sky. Each experiment offers complementary sensitivity to dark matter searches in a variety of target sizes, locations, and dark matter mass scales. We review results from recent gamma-ray experiments including anomalies some have attributed to dark matter. We also discuss how our gamma-ray observations complement other dark matter searches and the prospects for future experiments.
This book explains the Lorentz mathematical group in a language familiar to physicists. While the three-dimensional rotation group is one of the standard mathematical tools in physics, the Lorentz group of the four-dimensional Minkowski space is still very strange to most present-day physicists. It plays an essential role in understanding particles moving at close to light speed and is becoming the essential language for quantum optics, classical optics, and information science. The book is based on papers and books published by the authors on the representations of the Lorentz group based on harmonic oscillators and their applications to high-energy physics and to Wigner functions applicable to quantum optics. It also covers the two-by-two representations of the Lorentz group applicable to ray optics, including cavity, multilayer and lens optics, as well as representations of the Lorentz group applicable to Stokes parameters and the Poincar sphere on polarization optics.
Biophotonic diagnostics/biomedical spectroscopy can revolutionise the medical environment by providing a responsive and objective diagnostic environment. This book aims to explain the fundamentals of the physical techniques used combined with the particular requirements of analysing medical/clinical samples as a resource for any interested party. In addition, it will show the potential of this field for the future of medical science and act as a driver for translation across many different biological problems/questions.
Osteogenesis imperfecta (OI) is a disease encompassing a group of disorders mainly characterized by bone fragility and is the commonest form of heritable bone fragility. In this book, the clinical presentations with particular emphasis on rare phenotypes associated with OI are discussed together with molecular advances in diagnosis and treatment of OI.
Discusses our intimate relationship with and dependence on water, how the body regulates its water levels, and various pathophysiological states associated with impairments in body water homeostasis. The human body consists of 70-80% water. Therefore, concise control of water homeostasis is essential to survival and involves coordination of several systems.
The purpose of this presentation is to provide basic information about the operation and regulation of the cardiovascular and respiratory systems, as well as the properties of the blood and parenchymal cells, so that a fundamental understanding of the regulation of tissue oxygenation is achieved.
Provides a history of the Association for Computing Machinery (ACM), founded in 1947 and with a membership today of 100,000 worldwide. It profiles ACM's notable SIGs, active chapters, and individual members, setting ACM's history into a rich social and political context.

This book is a new look at one of the hottest topics in contemporary science, Dark Matter. It is the pioneering text dedicated to sterile neutrinos as candidate particles for Dark Matter, challenging some of the standard assumptions which may be true for some Dark Matter candidates but not for all. So, this can be seen either as an introduction to a specialized topic or an out-of-the-box introduction to the field of Dark Matter in general. No matter if you are a theoretical particle physicist, an observational astronomer, or a ground based experimentalist, no matter if you are a grad student or an active researcher, you can benefit from this text, for a simple reason: a non-standard candidate for Dark Matter can teach you a lot about what we truly know about our standard picture of how the Universe works.
Provides an introduction to the concept of symmetries in electromagnetism and explicit symmetry breaking. It begins with a brief background on the origin of the concept of symmetry and its meaning in fields such as architecture, mathematics and physics. This book unravels the beauty and excitement of this area to scientists and engineers.
In the past few decades, Magnetic Resonance Imaging (MRI) has become an indispensable tool in modern medicine, with MRI systems now available at every major hospital in the developed world. But for all its utility and prevalence, it is much less commonly understood and less readily explained than other common medical imaging techniques. Unlike optical, ultrasonic, X-ray (including CT), and nuclear medicine-based imaging, MRI does not rely primarily on simple transmission and/or reflection of energy, and the highest achievable resolution in MRI is orders of magnitude smaller that the smallest wavelength involved. In this book, MRI will be explained with emphasis on the magnetic fields required, their generation, their concomitant electric fields, the various interactions of all these fields with the subject being imaged, and the implications of these interactions to image quality and patient safety. Classical electromagnetics will be used to describe aspects from the fundamental phenomenon of nuclear precession through signal detection and MRI safety. Simple explanations and Illustrations combined with pertinent equations are designed to help the reader rapidly gain a fundamental understanding and an appreciation of this technology as it is used today, as well as ongoing advances that will increase its value in the future. Numerous references are included to facilitate further study with an emphasis on areas most directly related to electromagnetics.

This volume describes structural and functional properties of the cerebral circulation that are unique to the brain, an organ with high metabolic demands and the need for tight water and ion homeostasis.
The Nuclear Nonproliferation Treaty (NPT) has been the principal legal barrier to prevent the spread of nuclear weapons for the past forty-five years. However, many people are concerned about the continued viability of the NPT. This manuscript explores its viability and offers some possible solutions to ensure that the NPT will survive effectively for many years to come.
This book begins with an examination of the numbers of women in physics in English-speaking countries, before moving on to examine factors that affect girls and their decision to continue in science, right through to education and on into the problems that women in physics careers face.
This book is based on a commitment to teaching science to everybody. What may work for training professional scientists does not work for general science education. Students bring to the classrooms preconceived attitudes, as well as the emotional baggage called "e;"e;science anxiety."e;"e; Students may regard science as cold, unfriendly, and even inherently hostile and biased against women. This book has been designed to deal with each of these issues and results from research in both Denmark and the United States. The first chapter discusses student attitudes towards science and the second discusses science anxiety. The connection between the two is discussed before the introduction of constructivism as a pedagogy that can aid science learning if it also addresses attitudes and anxieties. Much of the book elucidates what the authors have learned as science teachers and science education researchers. They studied various groups including university students majoring in the sciences, mathematics, humanities, social sciences, business, nursing, and eduction; high school students; teachers' seminary students; science teachers at all levels from middle school through college; and science administrators. The insights of these groups constitute the most important feature of the book, and by sharing them, the authors hope to help their fellow science teachers to understand student attitudes about science, to recognize the connections between these and science anxiety, and to see how a pedagogy that takes these into account can improve science learning.
