On Art and Science: Tango of an Eternally Inseparable Duo (The Frontiers Collection)
by Shyam Wuppuluri Dali WuEinstein once remarked "After a certain high level of technical skill is achieved, science and art tend to coalesce in aesthetics, plasticity, and form. The greatest scientists are always artists as well". In this volume, some of the world’s leading thinkers come together to expound on the interrelations between sciences and arts. While one can segregate art and place it outside the scientific realm, it is, nevertheless, inextricably linked to our essential cognitive/emotional/perceptual modalities and abilities, and therefore lies alongside and in close contact with the method of science and philosophy. What inspiration can scientists draw from art and how can scientific spirit foster our understanding and creation of aesthetic works? How are art and science grounded in our cognition? What role does perception play in science and art? Are criteria for beauty in art and science the same? How does evolution shape our understanding of art? How do science, art and scientifico-artistic frameworks shape society as a whole and help us address its pressing issues? The epistemological and ontological aspects haunt artists, philosophers and scientists alike. The essays in this volume address these manifold questions while also elucidating the pragmatic role they play in our daily life.
On Being Certain: Believing You Are Right Even When You're Not
by Robert A. BurtonBurton challenges the notions of how we think about what we know. He shows that the feeling of certainty we have when we know something comes from sources beyond our control and knowledge. In fact, certainty is a mental sensation, rather than evidence of fact. Because this feeling of knowing seems like confirmation of knowledge, we tend to think of it as a product of reason. But an increasing body of evidence suggests that feelings such as certainty stem from primitive areas of the brain and are independent of active, conscious reflection and reasoning. The feeling of knowing happens to us; we cannot make it happen.
On Being Reformed: Debates over a Theological Identity (Christianities in the Trans-Atlantic World)
by Matthew C. Bingham Chris Caughey R. Scott Clark Crawford Gribben D. G. HartThis book provides a focus for future discussion in one of the most important debates within historical theology within the protestant tradition - the debate about the definition of a category of analysis that operates over five centuries of religious faith and practice and in a globalising religion. In March 2009, TIME magazine listed ‘the new Calvinism’ as being among the ‘ten ideas shaping the world.’ In response to this revitalisation of reformation thought, R. Scott Clark and D. G. Hart have proposed a definition of ‘Reformed’ that excludes many of the theologians who have done most to promote this driver of global religious change. In this book, the Clark-Hart proposal becomes the focus of a debate. Matthew Bingham, Chris Caughey, and Crawford Gribben suggest a broader and (they argue) more historically responsible definition for ‘Reformed,’ as Hart and Scott respond to their arguments.
On-Board Design Models and Algorithm for Communication Based Train Control and Tracking System (Power Electronics and Applications Series)
by Tanuja Patgar Kavitha Devi CSRailway systems have a long history of train protection and control, as to reduce the risk of train accidents. Many train control systems include automated communication between train and trackside equipment. But several different national systems are still facing cross-border rail traffic. Today, trains for cross-border traffic need to be equipped with train control systems that are installed on the tracks. This book covers the latest advances in Communication Based Train Control (CBTC) research in on-board components locomotive messaging systems, GPS sensors, communications wayside and switching networks. It also focuses on architecture and methodology using data fusion techniques. New wireless sensor integrated modeling techniques for tracking trains in satellite visible and low satellite visible environments are discussed. With a Tunnel Surveillance Integration model, the use of optimal control is necessary to improve train control performance, considering both train–ground communication and train control. The book begins with the background and evolution of train signaling and train control systems. It introduces the main features and architecture of CBTC systems and describes current challenging methods and successful implementations. This introductory book is very useful for Signal & Telecommunication engineers to get them acquainted with the technology used in CBTC, and help them in implementing the system suitable for Indian Railways. As this is a new technology, the information provided in this book is generic and will be subsequently revised after gaining further experience.
On Capitalism and Inequality: Progress and Poverty Revisited (Springer Praxis Bks.)
by Robert U. AyresCapitalism is under attack. Defenders say that capitalism has raised billions of people from poverty. But a central activity of capitalism today, Wall Street style, is speculation (gambling), using other people’s money, and privatizing the profits while socializing the debts. Skeptics argue that capitalism has redistributed the wealth of the planet in favor of a very few, meanwhile leaving the planet in bad shape and leaving billions of people out in the cold. Wealth is now extremely mal-distributed, opportunity is far from equal, and upward social mobility has declined significantly in recent decades. This book reviews the evidence and arguments pro and con in considerable detail.The evidence is mixed. The main virtue of capitalism is its emphasis on competition as a driver of innovation and, thus, of economic growth. It is true that economic growth has accelerated in recent centuries, and it is true that billions of people have been lifted from poverty. But it is not necessarily true that intense “winner take all” competition in the marketplace is the explanation for growth. Neoclassical economic theory posits that self-interest is the primary motive for all economic decisions, leaving little room for cooperation and even less for altruism. The theory applies to an unrealistic “model” of human behavior, known as Homo economicus or “economic man”, whose characteristic activity is buying or selling.The reason for using the adjective word “social” – as in socialism” or “social service” or “social democracy” -- is, essentially, to deny those postulates of standard economic theory. Real humans are not rational utility maximizers (whatever that is) and very often do things that are not in their own personal best interests. This can happen because other interests, such as family loyalty, professional, religious, or patriotic duty, may take precedence. Real people rarely behave like Homo economicus, who has rivals but no friends. He (or she) does not trust anyone, hence cannot cooperate with others, and can never create, or live in, a viable social system (or marriage). Yet social systems, ranging from families and tribes to firms, cities, and nations do (and must) exist or civilization cannot exist. A viable social system must not allow “winner takes all”. It must reallocate some of the societal wealth being created by competitive activities to support the young, the old and the weak, because all of those people have equal rights, if not the same luck or the same skills.Both competition and cooperation have important roles to play. A hybrid capitalism involving both is the only viable solution. The book ends with a specific suggestion, namely Universal Basic Income, or UBI.
On-Chip Instrumentation
by Neal StollonThis book provides an in-depth overview of on chip instrumentation technologies and various approaches taken in adding instrumentation to System on Chip (ASIC, ASSP, FPGA, etc.) design that are collectively becoming known as Design for Debug (DfD). On chip instruments are hardware based blocks that are added to a design for the specific purpose and improving the visibility of internal or embedded portions of the design (specific instruction flow in a processor, bus transaction in an on chip bus as examples) to improve the analysis or optimization capabilities for a SoC. DfD is the methodology and infrastructure that surrounds the instrumentation. Coverage includes specific design examples and discussion of implementations and DfD tradeoffs in a decision to design or select instrumentation or SoC that include instrumentation. Although the focus will be on hardware implementations, software and tools will be discussed in some detail.
On Coexistence Patterns: Hierarchies of Intricate Partially Symmetric Solutions to Stuart-Landau Oscillators with Nonlinear Global Coupling (Springer Theses)
by Sindre W. HauglandThis book is about coexistence patterns in ensembles of globally coupled nonlinear oscillators. Coexistence patterns in this respect are states of a dynamical system in which the dynamics in some parts of the system differ significantly from those in other parts, even though there is no underlying structural difference between the different parts. In other words, these asymmetric patterns emerge in a self-organized manner. As our main model, we use ensembles of various numbers of Stuart-Landau oscillators, all with the same natural frequency and all coupled equally strongly to each other. Employing computer simulations, bifurcation analysis and symmetry considerations, we uncover the mechanism behind a wide range of complex patterns found in these ensembles. Our starting point is the creation of so-called chimeras, which are subsequently treated within a new and broader context of related states.
On Desperate Ground: The Marines at The Reservoir, the Korean War's Greatest Battle
by Hampton Sides"On Desperate Ground is first-rate narrative history. Hampton Sides' characters are richly drawn, his background history engrossing, and his battle scenes bone-chillingly realistic--a great read."--Daniel James Brown, #1 New York Times bestselling author of The Boys in the BoatFrom the New York Times bestselling author of Ghost Soldiers and In the Kingdom of Ice, a chronicle of the extraordinary feats of heroism by Marines called on to do the impossible during the greatest battle of the Korean WarOn October 15, 1950, General Douglas MacArthur, Supreme Commander of UN troops in Korea, convinced President Harry Truman that the Communist forces of Kim Il-sung would be utterly defeated by Thanksgiving. The Chinese, he said with near certainty, would not intervene in the war.As he was speaking, 300,000 Red Chinese soldiers began secretly crossing the Manchurian border. Led by some 20,000 men of the First Marine Division, the Americans moved deep into the snowy mountains of North Korea, toward the trap Mao had set for the vainglorious MacArthur along the frozen shores of the Chosin Reservoir. What followed was one of the most heroic--and harrowing--operations in American military history, and one of the classic battles of all time. Faced with probable annihilation, and temperatures plunging to 20 degrees below zero, the surrounded, and hugely outnumbered, Marines fought through the enemy forces with ferocity, ingenuity, and nearly unimaginable courage as they marched their way to the sea.Hampton Sides' superb account of this epic clash relies on years of archival research, unpublished letters, declassified documents, and interviews with scores of Marines and Koreans who survived the siege. While expertly detailing the follies of the American leaders, On Desperate Ground is an immediate, grunt's-eye view of history, enthralling in its narrative pace and powerful in its portrayal of what ordinary men are capable of in the most extreme circumstances.Hampton Sides has been hailed by critics as one of the best nonfiction writers of his generation. As the Miami Herald wrote, "Sides has a novelist's eye for the propulsive elements that lend momentum and dramatic pace to the best nonfiction narratives."
On Escalation: Metaphors and Scenarios
by Herman KahnIn this widely discussed and influential book, Herman Kahn probes the dynamics of escalation and demonstrates how the intensification of conflict can be depicted by means of a definite escalation ladder, ascent of which brings opponents closer to all-out war. At each rung of the ladder, before the climb proceeds, decisions must be made based on numerous choices. Some are clear and obvious, others obscure, but the options are always there.Thermonuclear annihilation, says Kahn, is unlikely to come through accident; but nations may elect to climb the ladder to extinction. The basic material for the book was developed in briefings delivered by Kahn to military and civilian experts and revised in the light of his findings of a trip to Vietnam in the 1960s. In On Escalation he states the facts squarely. He asks the reader to face unemotionally the terrors of a world fully capable of suicide and to consider carefully the alternatives to such a path.In the never-never land of nuclear warfare, where nuclear incredulity is pervasive and paralyzing to the imagination even for the professional analyst, salient details of possible scenarios for the outbreak of war, and even more for war fighting, are largely unexplored or even unnoticed. For scenarios in which war is terminated, the issues and possibilities of which are almost completely unstudied, the situation is even worse. Kahn's discussion throws light on the terrain and gives the individual a sense of the range of possibilities and complexities involved and are useful.

On Exciton–Vibration and Exciton–Photon Interactions in Organic Semiconductors (Springer Theses)
by Antonios M. AlvertisWhat are the physical mechanisms that underlie the efficient generation and transfer of energy at the nanoscale? Nature seems to know the answer to this question, having optimised the process of photosynthesis in plants over millions of years of evolution. It is conceivable that humans could mimic this process using synthetic materials, and organic semiconductors have attracted a lot of attention in this respect. Once an organic semiconductor absorbs light, bound pairs of electrons with positively charged holes, termed `excitons’, are formed. Excitons behave as fundamental energy carriers, hence understanding the physics behind their efficient generation and transfer is critical to realising the potential of organic semiconductors for light-harvesting and other applications, such as LEDs and transistors. However, this problem is extremely challenging since excitons can interact very strongly with photons. Moreover, simultaneously with the exciton motion, organic molecules can vibrate in hundreds of possible ways, having a very strong effect on energy transfer. The description of these complex phenomena is often beyond the reach of standard quantum mechanical methods which rely on the assumption of weak interactions between excitons, photons and vibrations. In this thesis, Antonios Alvertis addresses this problem through the development and application of a variety of different theoretical methods to the description of these strong interactions, providing pedagogical explanations of the underlying physics. A comprehensive introduction to organic semiconductors is followed by a review of the background theory that is employed to approach the relevant research questions, and the theoretical results are presented in close connection with experiment, yielding valuable insights for experimentalists and theoreticians alike.
On Expertise: Cultivating Character, Goodwill, and Practical Wisdom (RSA Series in Transdisciplinary Rhetoric #17)
by Ashley Rose MehlenbacherThere is a deep distrust of experts in America today. Influenced by populist politics, many question or downright ignore the recommendations of scientists, scholars, and others with specialized training. It appears that expertise, a critical component of democratic life, no longer appeals to wide swaths of the body politic. On Expertise is a robust defense of the expert class. Ashley Rose Mehlenbacher examines modern and ancient theories of expertise through the lens of rhetoric and interviews some forty professionals, revealing how they understand their own expertise and how they came to be known as "experts." She shows that expertise requires not only knowledge and skill but also, crucially, an acknowledgment by others—both specialists and laypeople—that one is a credible authority. At its heart, expertise is a rhetorical construct, and to be persuasive, experts must have the ability to apply their knowledge and skills rightly—in the right way, at the right time, to achieve the right end. Ultimately, Mehlenbacher argues that experts apply their technical knowledge effectively and win others’ trust through acting prudently and cultivating goodwill. Timely, practical, and sophisticated, On Expertise provides vital scaffolding for our understanding of expertise and its real-world application. This book is essential for beginning the work of rehabilitating the expert class amid a politics of extreme populism and anti-intellectualism.

On Face Transplantation: Life and Ethics in Experimental Biomedicine
by Samuel Taylor-AlexanderDrawing together interview material, medical publications, and first-hand accounts, this book shows that what is being remade in the burgeoning medical field of face transplantation is not only the lives of patients, but also the very ways that state institutions, surgeons, and families make sense of rights, claims for inclusion, and life itself. This sophisticated account traces the work done by medical and bureaucratic elites to make the life threatening operation a clinical reality. Working within the context of increasing ethical scrutiny, their endeavour has resulted in the delineation of the 'ideal patient' of face transplantation: a person whose particular state of health and suffering allows the operation to be performed given current technical constraints. The operation has introduced into the lives of face transplant recipients a profoundly new sense of personhood in which they continue to negotiate questions of how to relate to their new biology and to those around them.
On Fact and Fraud: Cautionary Tales from the Front Lines of Science
by David GoodsteinAn in-depth look at scientific fraudFraud in science is not as easy to identify as one might think. When accusations of scientific misconduct occur, truth can often be elusive, and the cause of a scientist's ethical misstep isn't always clear. On Fact and Fraud looks at actual cases in which fraud was committed or alleged, explaining what constitutes scientific misconduct and what doesn't, and providing readers with the ethical foundations needed to discern and avoid fraud wherever it may arise.In David Goodstein's varied experience—as a physicist and educator, and as vice provost at Caltech, a job in which he was responsible for investigating all allegations of scientific misconduct—a deceptively simple question has come up time and again: what constitutes fraud in science? Here, Goodstein takes us on a tour of real controversies from the front lines of science and helps readers determine for themselves whether or not fraud occurred. Cases include, among others, those of Robert A. Millikan, whose historic measurement of the electron's charge has been maligned by accusations of fraud; Martin Fleischmann and Stanley Pons and their "discovery" of cold fusion; Victor Ninov and the supposed discovery of element 118; Jan Hendrik Schön from Bell Labs and his work in semiconductors; and J. Georg Bednorz and Karl Müller's discovery of high-temperature superconductivity, a seemingly impossible accomplishment that turned out to be real.On Fact and Fraud provides a user's guide to identifying, avoiding, and preventing fraud in science, along the way offering valuable insights into how modern science is practiced.
On Faith and Science
by Edward J. Larson Michael RuseA captivating historical survey of the key debates, questions, and controversies at the intersection of science and religion Throughout history, scientific discovery has clashed with religious dogma, creating conflict, controversy, and sometimes violent dispute. In this enlightening and accessible volume, distinguished historian and Pulitzer Prize–winning author Edward Larson and Michael Ruse, philosopher of science and Gifford Lecturer, offer their distinctive viewpoints on the sometimes contentious relationship between science and religion. The authors explore how scientists, philosophers, and theologians through time and today approach vitally important topics, including cosmology, geology, evolution, genetics, neurobiology, gender, and the environment. Broaching their subjects from both historical and philosophical perspectives, Larson and Ruse avoid rancor and polemic as they address many of the core issues currently under debate by the adherents of science and the advocates of faith, shedding light on the richly diverse field of ideas at the crossroads where science meets spiritual belief.
On Fertile Ground: A Natural History of Human Reproduction
by Peter T. EllisonReproduction is among the most basic of human biological functions, both for our distant ancestors and for ourselves, whether we live on the plains of Africa or in North American suburbs. Our reproductive biology unites us as a species, but it has also been an important engine of our evolution. In the way our bodies function today we can see both the imprint of our formative past and implications for our future. It is the infinitely subtle and endlessly dramatic story of human reproduction and its evolutionary context that Peter T. Ellison tells in On Fertile Ground. <P><P>Ranging from the latest achievements of modern fertility clinics to the lives of subsistence farmers in the rain forests of Africa, this book offers both a remarkably broad and a minutely detailed exploration of human reproduction. Ellison, a leading pioneer in the field, combines the perspectives of anthropology, stressing the range and variation of human experience; ecology, sensitive to the two-way interactions between humans and their environments; and evolutionary biology, emphasizing a functional understanding of human reproductive biology and its role in our evolutionary history. <P><P>Whether contrasting female athletes missing their periods and male athletes using anabolic steroids with Polish farm women and hunter-gatherers in Paraguay, or exploring the intricate choreography of an implanting embryo or of a nursing mother and her child, On Fertile Ground advances a rich and deeply satisfying explanation of the mechanisms by which we reproduce and the evolutionary forces behind their design.

On Flexibility: Recovery from Technological and Doctrinal Surprise on the Battlefield
by Meir FinkelThis book addresses one of the basic questions in military studies: How can armies cope effectively with technological and doctrinal surprises-ones that leave them vulnerable to new weapons systems and/or combat doctrines? Author Meir Finkel contends that the current paradigm-with its over-dependence on intelligence and an all-out effort to predict the nature of the future battlefield and the enemy's capabilities-generally doesn't work. Based on historical case analysis of successful "under-fire" recovery and failure to recover, he identifies the variables that have determined these outcomes, and he presents an innovative method for military force planning that will enables armies to deal with the uncertainties of future wars "in real time. " His proposed method combines conceptual, doctrinal, cognitive, command, organizational, and technological elements to produce optimal battlefield flexibility and adaptability. He then demonstrates that, when properly applied, this method can eliminate most obstacles to overcoming battlefield surprises.
On Gaia: A Critical Investigation of the Relationship between Life and Earth
by Toby TyrrellA critical examination of James Lovelock's controversial Gaia hypothesisOne of the enduring questions about our planet is how it has remained continuously habitable over vast stretches of geological time despite the fact that its atmosphere and climate are potentially unstable. James Lovelock's Gaia hypothesis posits that life itself has intervened in the regulation of the planetary environment in order to keep it stable and favorable for life. First proposed in the 1970s, Lovelock's hypothesis remains highly controversial and continues to provoke fierce debate. On Gaia undertakes the first in-depth investigation of the arguments put forward by Lovelock and others—and concludes that the evidence doesn't stack up in support of Gaia.Toby Tyrrell draws on the latest findings in fields as diverse as climate science, oceanography, atmospheric science, geology, ecology, and evolutionary biology. He takes readers to obscure corners of the natural world, from southern Africa where ancient rocks reveal that icebergs were once present near the equator, to mimics of cleaner fish on Indonesian reefs, to blind fish deep in Mexican caves. Tyrrell weaves these and many other intriguing observations into a comprehensive analysis of the major assertions and lines of argument underpinning Gaia, and finds that it is not a credible picture of how life and Earth interact.On Gaia reflects on the scientific evidence indicating that life and environment mutually affect each other, and proposes that feedbacks on Earth do not provide robust protection against the environment becoming uninhabitable—or against poor stewardship by us.
On Gallows Down: Place, Protest and Belonging
by Nicola ChesterPart nature writing, part memoir, On Gallows Down is an essential, unforgettable read for fans of Helen Macdonald, Terry Tempest Williams, and Robin Wall Kimmerer. Nicola Chester won the BBC Wildlife Magazine’s Nature Writer of the Year Award – this is her first book. On Gallows Down is a powerful, personal story shaped by a landscape; one that ripples and undulates with protest, change, hope – and the search for home. From the girl catching the eye of the “peace women” of Greenham Common to the young woman protesting the loss of ancient and beloved trees, and as a mother raising a family in a farm cottage in the shadow of grand, country estates, this is the story of how Nicola Chester came to write – as a means of protest. The story of how she discovered the rich seam of resistance that runs through her village of Newbury and its people – from the English Civil War to the Swing Riots and the battle against the Newbury Bypass. And the story of the hope she finds in the rewilding of Greenham Common after the military left, the stories told by the landscapes of Watership Down, the gallows perched high on Inkpen Beacon and Highclere Castle (the setting of Downtown Abbey). Nature is indelibly linked to belonging for Nicola. She charts her story through the walks she takes with her children across the chalk hills of the North Wessex Downs, though the song of the nightingale and the red kites, fieldfares, skylarks and lapwings that accompany her; the badger cubs she watches at night; the velvety mole she discovers in her garden and the cuckoo, whose return she awaits. On Gallows Down tells of how Nicola came to realize that it is she who can decide where she belongs, for home is a place in nature and imagination, which must be protected through words and actions. "We are writing for our very lives and for those wild lives we share this one, lonely planet with."—Nicola Chester
On Gauge Fixing Aspects of the Infrared Behavior of Yang-Mills Green Functions
by Markus Q. HuberQuarks are the main constituents of protons and neutrons and hence are important building blocks of all the matter that surrounds us. However, quarks have the intriguing property that they never appear as isolated single particles but only in bound states. This phenomenon is called confinement and has been a central research topic of elementary particle physics for the last few decades. In order to find the mechanism that forbids the existence of free quarks many approaches and ideas are being followed, but by now it has become clear that they are not mutually exclusive but illuminate the problem from different perspectives. Two such confinement scenarios are investigated in this thesis: Firstly, the importance of Abelian field components for the low-energy regime is corroborated, thus supporting the dual superconductor picture of confinement and secondly, the influence of the Gribov horizon on non-perturbative solutions is studied.
On Generalised Statistical Equilibrium and Discrete Quantum Gravity (Springer Theses)
by Isha KotechaAbsolute concepts of time and energy are integral to standard thermal physics, but background independent systems are devoid of them. This thesis explores the foundational question of generalising equilibrium statistical mechanics to background independent systems, and applies the resulting formulation to non-perturbative discrete quantum gravity. It offers a discussion of the rich interface of thermal physics and quantum gravity in this context, providing a broad contextualisation of such topics. This work details how standard tools from many-body physics can be generalised to discrete quantum gravity labelled with graph-based, or dual polyhedral, quanta that are common to various approaches like tensorial group field theory, loop quantum gravity, dynamical triangulations and lattice quantum gravity. It provides a systematic investigation, both conceptual and technical, of quantum gravitational Gibbs states, thermofield double vacuum states, and their application in condensate cosmology to probe questions of Big Bang singularity resolution and geometric inflation.
