SuperCooperators

by Martin Nowak Roger Highfield

EVOLUTION IS OFTEN PRESENTED AS A STRICTLY COMPETITIVE ENDEAVOR. This point of view has had serious implications for the way we see the mechanics of both science and culture. But scientists have long wondered how societies could have evolved without some measure of cooperation. And if there was cooperation involved, how could it have arisen from nature "red in tooth and claw"? Martin Nowak, one of the world's experts on evolution and game theory, working here with bestselling science writer Roger Highfield, turns an important aspect of evolutionary theory on its head to explain why cooperation, not competition, has always been the key to the evolution of complexity. He offers a new explanation for the origin of life and a new theory for the origins of language, biology's second greatest information revolution after the emergence of genes. SuperCooperators also brings to light his game-changing work on disease. Cancer is fundamentally a failure of the body's cells to cooperate, Nowak has discovered, but organs are cleverly designed to foster cooperation, and he explains how this new understanding can be used in novel cancer treatments. Nowak and Highfield examine the phenomena of reciprocity, reputation, and reward, explaining how selfless behavior arises naturally from competition; how forgiveness, generosity, and kindness have a mathematical rationale; how companies can be better designed to promote cooperation; and how there is remarkable overlap between the recipe for cooperation that arises from quantitative analysis and the codes of conduct seen in major religions, such as the Golden Rule. In his first book written for a wide audience, this hugely influential scientist explains his cutting-edge research into the mysteries of cooperation, from the rise of multicellular life to Good Samaritans. With wit and clarity, Nowak and Highfield make the case that cooperation, not competition, is the defining human trait. SuperCooperators will expand our understanding of evolution and provoke debate for years to come.

Supercritical Fluid Technology: Reviews in Modern Theory and Applications (CRC Press Revivals)

by Thomas J. Bruno James F. Ely

In this volume, we have collected a series of reviews that cover both experimental and theoretical work geared toward the more exact requirements of current SFE applications. While we have artificially divided the volume into experimental and theoretical sections, natural overlaps will be apparent. Many of the papers on experimental and theoretical sections, natural overlaps will be apparent. Many of the papers on experimental technique contain discussions on equation of state correlations. Indeed, a good deal of the experimental work is intimately tied to a mathematical description of fluid mixtures. The theoretical section presents reviews that cover the modern theory of critical phenomena, methods to correlate near critical experimental results and approaches to understanding the behavior of near critical fluids from microscopic theory. It is hoped that the scope of these reviews will provide the reader with the basis to further develop our understanding of the behavior of supercritical fluids.

Supercritical Water Processing Technologies for Environment, Energy and Nanomaterial Applications

by Shuzhong Wang Donghai Xu Yang Guo Xingying Tang Yuzhen Wang Jie Zhang Honghe Ma Lili Qian Yanhui Li

This book systematically presents the technical aspects of supercritical water oxidation and supercritical water gasification for energy and environmental applications, which include reactor design, construction materials, corrosion, salt precipitation, etc. The book provides a comprehensive introduction to the properties of supercritical water, and the industrial applications, reaction mechanisms and reaction kinetics of supercritical water oxidation (SCWO) and supercritical water gasification (SCWG). The reactions occurring in supercritical water are complex, and studying their reaction mechanisms is of great importance for the development of supercritical water processing technologies. Accordingly, the book explains the oxidative mechanisms and kinetics of organic matter in supercritical water in detail. However, the harsh reaction conditions in supercritical water can easily create severe reactor corrosion and salt deposition problems. Therefore, the book also comprehensively reports on the mechanism analysis, state of research, and development trends regarding these two problems. Lastly, the book summarizes the development of supercritical water processing technologies, including studies on SCWO and SCWG, as well as near-zero-emission systems of pollutants based on SCWO technology. In short, the book provides a wealth of valuable information for all readers who are interested in using SCWO for organic waste treatment, and in using SCWG for hydrogen production with wet biomass.

Superdove: How the Pigeon Took Manhattan ... And the World

by Courtney Humphries

Why do we see pigeons as lowly urban pests and how did they become such common city dwellers? Courtney Humphries traces the natural history of the pigeon, recounting how these shy birds that once made their homes on the sparse cliffs of sea coasts came to dominate our urban public spaces. While detailing this evolution, Humphries introduces us to synanthropy: The concept that animals can become dependent on humans without ceasing to be wild; they can adapt to the cityscape as if it were a field or a forest.Superdove simultaneously explores the pigeon's cultural transformation, from its life in the dovecotes of ancient Egypt to its service in the trenches of World War I, to its feats within the pigeon-racing societies of today. While the dove is traditionally recognized as a symbol of peace, the pigeon has long inspired a different sort of fetishistic devotion from breeders, eaters, and artists—and from those who recognized and exploited the pigeon's astounding abilities. Because of their fecundity, pigeons were symbols of fertility associated with Aphrodite, while their keen ability to find their way home made them ideal messengers and even pilots. Their usefulness largely forgotten, today's pigeons have become as ubiquitous and reviled as rats. But Superdove reveals something more surprising: By using pigeons for our own purposes, we humans have changed their evolution. And in doing so, we have helped make pigeons the ideal city dwellers they are today. In the tradition of Rats, the book that made its namesake rodents famous, Superdove is the fascinating story of the pigeon's journey from the wild to the city—the home they'll never leave.

Superficiales: ¿Qué está haciendo Internet con nuestras mentes?

by Nicholas Carr

¿Qué está haciendo Internet con nuestras mentes? Este libro cambiará para siempre nuestro modo de entender y aprovechar las nuevas tecnologías. «¿Google nos vuelve estúpidos?» Nicholas Carr condensó así, en el título de un célebre artículo, uno de los debates más importantes de nuestro tiempo: mientras disfrutamos de las bondades de la Red, ¿estamos sacrificando nuestra capacidad para leer y pensar con profundidad? En este libro, Carr desarrolla sus argumentos para crear el más revelador análisis de las consecuencias intelectuales y culturales de Internet publicado hasta la fecha. Nuestro cerebro, como demuestran las evidencias científicas e históricas, cambia en respuesta a nuestras experiencias, y la tecnología que usamos para encontrar, almacenar y compartir información puede, literalmente, alterar nuestros procesos neuronales. Además, cada tecnología de la información conlleva una ética intelectual. Así como el libro impreso servía para centrar nuestra atención, fomentando el pensamiento profundo y creativo, Internet fomenta el picoteo rápido y distraído de pequeños fragmentos de información de muchas fuentes. Su ética es una ética industrial, de la velocidad y la eficiencia. La Red nos está reconfigurando a su propia imagen, volviéndonos más hábiles para manejar y ojear superficialmente la información pero menos capaces de concentración, contemplación y reflexión. Este libro cambiará para siempre nuestro modo de entender y aprovechar las nuevas tecnologías. Reseñas:«Absorbente y perturbador. Todos bromeamos sobre cómo Internet nos está convirtiendo, y especialmente a nuestros hijos, en cabezas de chorlito acelerados incapaces de meditaciones profundas. No es ninguna broma, insiste Carr, y a mí me ha convencido.»John Horgan, The Wall Street Journal «Una réplica calmada y elocuente a aquellos que afirman que la cultura digital es inofensiva, que afirman, de hecho, que nos estamos volviendo más listos cada minuto que pasa simplemente porque podemos conectarnos a un ordenador y dejarnos llevar por un interminable carrusel de links.»Julia Keller, Chicago Tribune

Superfluid: How a Quantum Fluid Revolutionized Modern Science

by J. G. Weisend II

Unless you are a specialist or watch a lot of obscure YouTube videos you have probably never heard of He II or superfluid helium. This substance, a unique liquid form of the element helium, is produced and used in multi-ton quantities to enable much of modern science. Altogether, He II is at the heart of more than a dozen large scale scientific facilities world-wide representing an investment of tens of billions of dollars. It cools the magnets and cavities that contain and accelerate the particle beams at the Large Hadron Collider and is also used in accelerators for the study of rare isotopes and nuclear astrophysics. This little known liquid is, in reality, one of the enabling technologies of the future. A manifestation of quantum mechanics, He II exhibits amazing behaviors. It can flow up the side of a container against gravity, it can move through small openings without friction, and it can transfer heat extremely efficiently via a mechanism not seen elsewhere in nature. This book tells the story of He II. It describes the discovery of the fluid, the observation and understanding of its behavior, the development of underlying theory and the evolution of He II from a laboratory curiosity to an industrial-scale coolant. The current and possible future applications of He II are described. Like all science and engineering, the story of He II is a human story and the role that personalities, politics, communication, cooperation and competition play in the development of He II is captured here as well. World-famous physicists such as Lev Landau, Richard Feynman, Peter Kapitza and Kurt Mendelssohn are key players in the story, while secret police from two different countries have a walk-on role. This work is meant for the general reader. Without assuming any expertise in physics, engineering or mathematics, it illuminates for the general public a little-known area of science and engineering and shows why it matters. As it turns out, it’s also a good story.

Superfoods: Cultural and Scientific Perspectives (Food and Health)

by Jeffrey P. Miller Charlene Van Buiten

Superfoods have come to the forefront of the public imagination due to a combination of presumed health benefits and cultural mystique. Much of the literature on these foods, however, is based upon rostrums and diet plans that accept the health claims of superfoods without subjecting them to rigorous scrutiny. Superfoods: Cultural and Scientific Perspectives examines these food products from a blended science and cultural viewpoint, presenting a balanced, evidence-based view of each food item. Following a discussion of “superfoods” as a category, the book’s chapters examine individual superfoods, including but not limited to: avocados, chocolate, wine, berries, and fish oil. Presented in a systemic manner, each chapter provides a cultural history of the superfood; a survey of the current state of nutritional research on the food and its health claims; an exploration of related science topics to enhance understanding of the superfood, (i.e., a survey of the botany, biology, or chemistry studies); social issues associated with the superfood, such as sustainability, environmental health concerns, agricultural issues, fair trade and marketing issues; and one to three recipes featuring the superfood. This combination of scientific and cultural perspectives makes Superfoods an invaluable reference for academics, industry professionals, and lay-readers alike.

Superfund And Mining Megasites: Lessons From The Coeur D'alene River Basin

by National Research Council of the National Academies

For more than 100 years, the Coeur d' Alene River Basin has been known as "The Silver Valley" for being one of the most productive silver, lead, and zinc mining areas in the United States. Over time, high levels of metals (including lead, arsenic, cadmium, and zinc) were discovered in the local environment and elevated blood lead levels were found in children in communities near the metal-refining and smelter complex. In 1983, the U.S. Environmental Protection Agency (EPA) listed a 21-square mile mining area in northern Idaho as a Superfund site. EPA extended those boundaries in 1998 to include areas throughout the 1500-square mile area Coeur d'Alene River Basin project area. Under Superfund, EPA has developed a plan to clean up the contaminated area that will cost an estimated $359 million over 3 decades--and this effort is only the first step in the cleanup process. Superfund and Mining Megasites: Lessons from Coeur d'Alene River Basin evaluates the issues and concerns that have been raised regarding EPA's decisions about cleaning up the area. The scientific and technical practices used by EPA to make decisions about human health risks at the Coeur d'Alene River Basin Superfund site are generally sound; however, there are substantial concerns regarding environmental protection decisions, particularly dealing with the effectiveness of long-term plans.

Supergeometry, Super Riemann Surfaces and the Superconformal Action Functional (Lecture Notes in Mathematics #2230)

by Enno Keßler

This book treats the two-dimensional non-linear supersymmetric sigma model or spinning string from the perspective of supergeometry. The objective is to understand its symmetries as geometric properties of super Riemann surfaces, which are particular complex super manifolds of dimension 1|1.The first part gives an introduction to the super differential geometry of families of super manifolds. Appropriate generalizations of principal bundles, smooth families of complex manifolds and integration theory are developed.The second part studies uniformization, U(1)-structures and connections on Super Riemann surfaces and shows how the latter can be viewed as extensions of Riemann surfaces by a gravitino field. A natural geometric action functional on super Riemann surfaces is shown to reproduce the action functional of the non-linear supersymmetric sigma model using a component field formalism. The conserved currents of this action can be identified as infinitesimal deformations of the super Riemann surface. This is in surprising analogy to the theory of Riemann surfaces and the harmonic action functional on them.This volume is aimed at both theoretical physicists interested in a careful treatment of the subject and mathematicians who want to become acquainted with the potential applications of this beautiful theory.
