On Desperate Ground: The Marines at The Reservoir, the Korean War's Greatest Battle
by Hampton SidesFrom the New York Times bestselling author of Blood and Thunder and Ghost Soldiers, a chronicle of the extraordinary feats of heroism by Marines called on to do the impossible during the greatest battle of the Korean War."Superb ... A masterpiece of thorough research, deft pacing and arresting detail...This war story—the fight to break out of a frozen hell near the Chosin Reservoir—has been told many times before. But Sides tells it exceedingly well, with fresh research, gritty scenes and cinematic sweep." —The Washington PostOn 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marched their way to the sea.Hampton Sides' superb account of this epic clash relies on years of archival research, unpublished letters, declassified documents, and interviews with scores of Marines and Koreans who survived the siege.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 Dreams and the East: Notes of the 1933 Berlin Seminar (Philemon Foundation Series)
by C. G. Jung Heinrich ZimmerJung&’s landmark seminar on the symbolism of yoga and its applications to dream analysisIn the summer of 1933, C. G. Jung conducted a seminar in Berlin attended by a large audience of some 150 people, including several Jewish Jungians who would soon leave Germany. Hitler had begun consolidating his position as dictator and these students were distressed at Jung&’s recent decision to accept the presidency of a German professional psychotherapy society that was rapidly becoming Nazified and purged of Jews. On Dreams and the East makes these seminar sessions widely available for the first time, offering tantalizing insights into Jung&’s evolving understanding of yoga and the realization of the self.The seminar commences with a presentation on the psychology of yoga by noted Indologist and linguist Heinrich Zimmer, whose collaboration in these talks reflects Jung&’s growing engagement with the Hindu tradition, particularly Tantric yoga. Jung analyzes a series of dreams of a middle-aged male patient, focusing on mandalas and the centering process. He reflects on related motifs in alchemical symbolism, Navaho healing drawings, Mithraism, baptism symbolism, the foundation of Rome, ecclesiastic dances, and labyrinths, drawing connections with the symbolism of yoga and Tantra.Featuring a richly documented introduction by Giovanni Sorge, On Dreams and the East opens a window on Jung&’s deepening exploration of Eastern thought and the comparative study of the individuation process at a critical juncture in his life and work.
On Earth as in Heaven: Ecological Vision and Initiatives of Ecumenical Patriarch Bartholomew (Orthodox Christianity and Contemporary Thought)
by Ecumenical Patriarch BartholomewOver the past two decades, the world has witnessed alarming environmental degradation—climate change, the loss of biodiversity, and the pollution of natural resources—together with a failure to implement environmental policies and an ever-widening gap between rich and poor. As this new volume of his writings reveals, Ecumenical Patriarch Bartholomew has continually proclaimed the primacy of spiritual values in determining environmental ethics and action. For him, the predicament we face is not primarily ecological but in fact spiritual: The ultimate aim is to see all things in God, and God in all things.On Earth as in Heaven demonstrates just why His All Holiness has been dubbed the “Green Patriarch” by former Vice President Al Gore (recipient of the Nobel Peace Prize for his environmental activism) and the media.This third and final volume of the spiritual leader’s selected writings showcases his statements on environmental degradation, global warming, and climate change. It contains numerous speeches and interviews in various circumstances, including ecological symposia, academic seminars, and regional and international events, over the first twenty years of his ministry. This volume also encompasses a selection of pastoral letters and exhortations—ecclesiastical, ecumenical, and academic—by His All Holiness for occasions such as Easter and Christmas, honorary doctorates, and academic awards.On Earth as in Heaven is a rich collection, essential for religious scholars, those looking for a deeper understanding of Orthodox Christianity, and anyone concerned with the environmental and social issues we face today.On Earth as in Heaven is available from the Knowledge Unlatched on an open-access basis.
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.

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.

On Giving Up
by Adam PhillipsOne of The New York Times Critics' Picks of the YearFrom acclaimed psychoanalyst Adam Phillips, a meditation on what we must give up to feel more alive.To give up or not to give up?The question can feel inescapable but the answer is never simple.Giving up our supposed vices is one thing; giving up on life itself is quite another. One form of self-sacrifice feels positive, something to admire and aspire to, while the other is profoundly unsettling, if not actively undesirable.There are always, it turns out, both good and bad sacrifices, but it is not always clear beforehand which is which. We give something up because we believe we can no longer go on as we are. In this sense, giving up is a critical moment—an attempt to make a different future.In On Giving Up, the acclaimed psychoanalyst Adam Phillips illuminates both the gaps and the connections between the many ways of giving up and helps us to address the central question: What must we give up in order to feel more alive?
On Graph Approaches to Contextuality and their Role in Quantum Theory (SpringerBriefs in Mathematics)
by Barbara Amaral Marcelo Terra CunhaThis book explores two of the most striking features of quantum theory – contextuality and nonlocality – using a formulation based on graph theory. Quantum theory provides a set of rules to predict probabilities of different outcomes in different experimental settings, and both contextuality and nonlocality play a fundamental role in interpreting the outcomes. In this work, the authors highlight how the graph approach can lead to a better understanding of this theory and its applications. After presenting basic definitions and explaining the non-contextuality hypothesis, the book describes contextuality scenarios using compatibility hypergraphs. It then introduces the exclusivity graph approach, which relates a number of important graph-theoretical concepts to contextuality. It also presents open problems such as the so-called Exclusivity Principle, as well as a selection of important topics, like sheaf-theoretical approach, hypergraph approach, and alternative proofs of contextuality.
On Gravity: A Brief Tour of a Weighty Subject
by A. ZeeA brief introduction to gravity through Einstein’s general theory of relativityOf the four fundamental forces of nature, gravity might be the least understood and yet the one with which we are most intimate. From the months each of us spent suspended in the womb anticipating birth to the moments when we wait for sleep to transport us to other realities, we are always aware of gravity. In On Gravity, physicist A. Zee combines profound depth with incisive accessibility to take us on an original and compelling tour of Einstein's general theory of relativity. Inspired by Einstein's audacious suggestion that spacetime could ripple, Zee begins with the stunning discovery of gravity waves. He goes on to explain how gravity can be understood in comparison to other classical field theories, presents the idea of curved spacetime and the action principle, and explores cutting-edge topics, including black holes and Hawking radiation. Zee travels as far as the theory reaches, leaving us with tantalizing hints of the utterly unknown, from the intransigence of quantum gravity to the mysteries of dark matter and energy.Concise and precise, and infused with Zee's signature warmth and freshness of style, On Gravity opens a unique pathway to comprehending relativity and gaining deep insight into gravity, spacetime, and the workings of the universe.
On Growth and Form
by D'Arcy Wentworth ThompsonSir D'Arcy W. Thompson CB FRS FRSE (1860-1948) was a Scottish biologist, mathematician, and classics scholar. A pioneering mathematical biologist, he is mainly remembered as the author of ON GROWTH AND FORM, an influential work of striking originality and elegance. The central theme of ON GROWTH AND FORM is that biologists of its author's day overemphasized evolution as the fundamental determinant of the form and structure of living organisms, and under-emphasized the roles of physical laws and mechanics. Peter Medawar who was the 1960 Nobel Laureate in Medicine called ON GROWTH AND FORM "the finest work of literature in all the annals of science that have been recorded in the English tongue."
