Light Pollution in Metropolises: Analysis, Impacts and Solutions

by Emlyn Etienne Goronczy

Light pollution (light smog, light pollution or light emissions) is a fundamental problem in metropolises with effects on flora, fauna and people. Accordingly, the first section of the book discusses the basics of light pollution and its effects on various organisms. The characteristics of light smog in the cities of Hanover, Warsaw, Boston, New York City and Toronto are then analysed and compared. But how can the problem be tackled? Existing measures for the prevention of light pollution are discussed and further novel approaches are shown by comparing the metropolises. The book is aimed primarily at practitioners in this field and helps to identify sources of emissions and identify suitable reduction measures. This book is a translation of the original German edition „Lichtverschmutzung in Metropolen“ by Emlyn Etienne Goronczy, published by Springer Fachmedien Wiesbaden GmbH in 2018. The translation was done with the help of artificial intelligence (machine translation by the service DeepL.com). A subsequent human revision was done primarily in terms of content, so that the book will read stylistically differently from a conventional translation. Springer Nature works continuously to further the development of tools for the production of books and on the related technologies to support the authors.

Light-Matter Interactions Towards the Nanoscale (NATO Science for Peace and Security Series B: Physics and Biophysics)

by Maura Cesaria Antonio Calà Lesina John Collins

The investigation of light-matter interactions in materials, especially those on the nanoscale, represents perhaps the most promising avenue for scientific progress in the fields of photonics and plasmonics. This book examines a variety of topics, starting from fundamental principles, leading to the current state of the art research. For example, this volume includes a chapter on the sensing of biological molecules with optical resonators (microspheres) combined with plasmonic systems, where the response this system are described in a fundamental and elegant manner using coupled mode theory. Symmetry plays a major role in the book. One chapter on time reversal symmetry in electromagnetic theory describes how to control the properties of light (e.g. scattering and directionality of the flow of light) in materials with certain topological invariants. Another chapter where symmetry is prominent reformulates, using a gentle and pedagogical approach, Maxwell’s Equations into a new set of fields that reveal a “handedness” symmetry in electromagnetic theory, which can be applied to photonic systems in, for example, the sensing of chiral molecules and understanding the conditions for zero reflection. Also, for students and researchers starting in the field of nanoplasmonics, the book includes a tutorial on the finite element time domain simulation of nanoplasmonic systems. Other topics include photonic systems for quantum computing, nanoplasmonics, and optical properties of nano and bulk materials. The authors take a pedagogical approach to their topic, making the book an excellent reference for graduate students and scientists starting in the fields of photonics or plasmonics.

Light It Up: The Marine Eye for Battle in the War for Iraq

by John Pettegrew

Examines the U.S. Marines’ visual culture of combat in the Iraq War.American military power in the War on Terror has increasingly depended on the capacity to see the enemy. The act of seeing—enhanced by electronic and digital technologies—has separated shooter from target, eliminating risk of bodily harm to the remote warrior, while YouTube videos eroticize pulling the trigger and video games blur the line between simulated play and fighting.Light It Up examines the visual culture of the early twenty-first century military. Focusing on the Marine Corps, which played a critical part in the invasion and occupation of Iraq, John Pettegrew argues that U.S. military force in the Iraq War was projected through an "optics of combat." Powerful military technology developed in the Iraq and Afghanistan wars has placed war in a new posthuman era.Pettegrew’s interviews with marines, as well as his analysis of first-person shooter videogames and combat footage, lead to startling insights into the militarization of popular digital culture. An essential study for readers interested in modern warfare, policy makers, and historians of technology, war, and visual and military culture.

A ‘Light’ Guide to Energy Savings in Transport

by Conor Molloy

This book is a practical guide to finding and delivering energy savings opportunities in transport operations for professional energy managers and energy auditors. Globally, transport is one of the fastest growing energy consumers and emitters of greenhouse gases, predominantly CO2. The transport sector is also changing quickly ("more change in the last 5 years than in the last 50" – Mary Barra, CEO General Motors). After distance, unladen vehicle weight is the biggest driver of energy consumption in transport, hence this book is called the ‘light’ guide – tongue in cheek. Be warned transport is a huge and complex topic. This practical guide from the convener of EN16247-4:2014, the first European energy audit standard for transport, takes a pragmatic approach to delivering measurable energy and emissions reductions in transport operations. Lessons learnt from the author’s 17 years of experience in persuading operators to deliver measured energy savings in transport are interwoven with tools, tips and shortcuts. These will help energy managers and auditors deliver effective transport energy audits that identify opportunities, prompting action, measured savings and, most importantly, being invited back!

Light Driven Micromachines

by George K. Knopf Kenji Uchino

In Light Driven Micromachines, the fundamental principles and unique characteristics of light driven material structures, simple mechanisms and integrated machines are explored. Very small light driven systems provide a number of interesting features and unique design opportunities because streams of photons deliver energy into the system and provide the control signal used to regulate the response of the micron sized device. Through innovative material design and clever component fabrication, these optically powered tiny machines can be created to perform mechanical work when exposed to varying light intensity, wavelength, phase, and/or polarization. The book begins with the scientific background necessary to understand the nature of light and how light can initiate physical movement by inducing material deformation or altering the surrounding environment to impose micro-forces on the actuating mechanisms. The impact of physical size on the performance of light driven mechanisms and machines is discussed, and the nature of light–material interactions is reviewed. These interactions enable very small objects and mechanical components to be trapped and manipulated by a focused light beam, or produce local temperature gradients that force certain materials to undergo shape transformation. Advanced phase transition gels, polymers, carbon-based films and piezoelectric ceramics that exhibit direct light-to-mechanical energy conversion are examined from the perspective of designing optically driven actuators and mechanical systems. The ability of light to create photothermal effects that drive microfluidic processes and initiate the phase transformation of temperature sensitive shape memory materials are also explored in the book. This compendium seeks to inspire the next generation of scientists and engineers by presenting the fundamental principles of this emerging interdisciplinary technology and exploring how the properties of light can be exploited for microfluidic, microrobotic, biomedical and space applications.

The Light Ages: The Surprising Story Of Medieval Science

by Seb Falk

An illuminating guide to the scientific and technological achievements of the Middle Ages through the life of a crusading astronomer-monk. Soaring Gothic cathedrals, violent crusades, the Black Death: these are the dramatic forces that shaped the medieval era. But the so-called Dark Ages also gave us the first universities, eyeglasses, and mechanical clocks. As medieval thinkers sought to understand the world around them, from the passing of the seasons to the stars in the sky, they came to develop a vibrant scientific culture. In The Light Ages, Cambridge science historian Seb Falk takes us on a tour of medieval science through the eyes of one fourteenth-century monk, John of Westwyk. Born in a rural manor, educated in England’s grandest monastery, and then exiled to a clifftop priory, Westwyk was an intrepid crusader, inventor, and astrologer. From multiplying Roman numerals to navigating by the stars, curing disease, and telling time with an ancient astrolabe, we learn emerging science alongside Westwyk and travel with him through the length and breadth of England and beyond its shores. On our way, we encounter a remarkable cast of characters: the clock-building English abbot with leprosy, the French craftsman-turned-spy, and the Persian polymath who founded the world’s most advanced observatory. The Light Ages offers a gripping story of the struggles and successes of an ordinary man in a precarious world and conjures a vivid picture of medieval life as we have never seen it before. An enlightening history that argues that these times weren’t so dark after all, The Light Ages shows how medieval ideas continue to color how we see the world today.

Liganded silver and gold quantum clusters. Towards a new class of nonlinear optical nanomaterials (SpringerBriefs in Materials)

by Vlasta Bonačić-Koutecký Rodolphe Antoine

Metallic quantum clusters belonging to intermediate size regime between two and few hundred of atoms, represent unique building blocks of new materials. Nonlinear optical (NLO) characteristics of liganded silver and gold quantum clusters reveal remarkable features which can be tuned by size, structure and composition. The two-photon absorption cross sections of liganded noble metal quantum clusters are several orders of magnitude larger than that of commercially-available dyes. Therefore, the fundamental photophysical understanding of those two-photon processes in liganded clusters with few metal atoms deserve special attention, in particularly in context of finding the mechanisms responsible for these properties. A broad range of state-of-the-art experimental methods to determine nonlinear optical properties (i.e. two-photon absorption, two-photon excited fluorescence and second harmonic generation) of quantum clusters are presented. The experimental setup and underlying physical concepts are described. Furthermore, the theoretical models and corresponding approaches are used allowing to explain the experimental observations and simultaneously offering the possibility to deduce the key factors necessary to design new classes of nanoclusters with large NLO properties. Additionally, selected studied cases of liganded silver and gold quantum clusters with focus on their NLO properties will be presented as promising candidates for applications in imaging techniques such as fluorescence microscopy or Second-Harmonic Generation microscopy.
