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.

Superhuman

by Lori Oliwenstein Professor Lord Robert Winston

Accompanying the major new BBC documentary series, Superhuman explores the human bodys astonishing ability to heal, renew and regenerate itself. In recording the before, during and after of radical operations on real people it introduces us to the pioneering efforts of medical teams and alerts us to the ethical issues that new medical advances raise. Over six chapters Superhuman addresses significant developments within six key medical areas: cancer, infection, transplantation, trauma, repair and reproduction. Acknowledging the debt modern physicians owe to yesterday Superhuman begins by investigating the human bodys innate abilities to heal itself. And, as we gladly launch ourselves into an age of biotechnology, it questions whether we might now use all the information available to us to comprehend finally how our bodies work? If we can achieve that, perhaps becoming superhuman is truly within our reach. Chapter one introduces us to the trauma surgeons who have discovered that the shock that follows trauma can prove beneficial in saving the body and the brain. Chapter two chronicles the astonishing technology now being used in medical transplants and the contentious issues these processes excite. Should technology continue to develop apace how are doctors and patients to choose between using an artificial limb created specifically for a patient, a human limb grown from the patients own genetic information, or the alternative solutions offered by the animal kingdom? And is intervention of true benefit to the patient if it requires a lifetime of immuno-suppressing drugs? The recent successes of the Human Genome Project have dissolved the boundaries of regeneration with made-to-order organs no longer beyond our limits. Chapter three presents the scientists responsible for engineering human tissue from materials found in the body and outlines how they might help us might claim our lost powers of regeneration. Chapter four relates how we are faring in the battle against the old enemy cancer and tells how experts in this field are trying to regain control of the cancer cells that turn against us. Chapter five explains how we strive to combat the threats we all face living in a modern world teeming with globetrotters who share one feature we're all potential contagion-carriers. Superhuman goes on to inform of the dangers of pushing too far to eradicate infectious disease from our lives completely. Chapter six spotlights an area of considerable debate that will possibly alter the course of human evolution fertility and genetic manipulation. Superhuman discusses both the advantages and the dangers of new technologies in this area, arguing that they have many positive applications and that often the hazards are overstated, solely through fear. In an attempt never to lose sight of our humanity while inviting the superhuman in us all to work, Superhuman encourages a holistic approach to medicine and an open forum for the discussion of the future of medical science.

Superhuman: Life at the Extremes of Our Capacity

by Dr Rowan Hooper

From evolutionary biologist Rowan Hooper, an awe-inspiring look into the extremes of human ability—and what they tell us about our own potential.In 1997, an endurance runner named Yiannis Kouros ran 188 miles in twenty-four hours. Akira Haraguchi, a sixty year-old man in Tokyo, can recite pi to the 100,000th decimal point. John Nunn was accepted to Oxford University at age 15, the youngest undergraduate in 500 years. After a horrific attack by her estranged husband, Carmen Tarleton was left with burns to over eighty percent of her body. One of her surgeons said her injuries “were beyond anything we have ever seen.” After a three-month coma, multiple skin grafts, and successful face transplant, Tarleton is now a motivational speaker. What does it feel like to be exceptional? And what does it take to get there? Why can some people achieve greatness when others can’t, no matter how hard they try? Just how much potential does our species have? Evolutionary biologist Rowan Hooper has the answers. In Superhuman he takes us on a breathtaking tour of the peaks of human achievement that shows us what it feels like to be extraordinary—and what it takes to get there. Drawing on interviews with these “superhumans” and those who have studied them, Hooper assesses the science and genetics of peak potential. His case studies are as inspirational as they are varied, highlighting feats of endurance, strength, intelligence, and memory. Superhuman is a fascinating, eye-opening, and inspiring celebration for anyone who ever felt that they might be able to do something extraordinary in life, for those who simply want to succeed, and for anyone interested in the sublime possibilities of humankind.

Superhydrophobic Surfaces

by Kash L. Mittal Alain Carre

Superhydrophobic surfaces (water contact angles higher than 150a ) can only be achieved by a combination of hydrophobicity (low surface energy materials) with appropriate surface texture. In nature one can find an array of impressive and elegant examples of superhydrophobic surfaces. For example, on a lotus leaf rain drops bounce off after impact,

Superior: The Return of Race Science

by Angela Saini

An astute and timely examination of the re-emergence of scientific research into racial differencesSuperior tells the disturbing story of the persistent thread of belief in biological racial differences in the world of science.After the horrors of the Nazi regime in WWII, the mainstream scientific world turned its back on eugenics and the study of racial difference. But a worldwide network of unrepentant eugenicists quietly founded journals and funded research, providing the kind of shoddy studies that were ultimately cited in Richard Hernstein's and Charles Murray's 1994 title, The Bell Curve, which purported to show differences in intelligence among races. If the vast majority of scientists and scholars disavowed these ideas, and considered race a social construct, it was still an idea that managed to somehow make its way into the research into the human genome that began in earnest in the mid-1990s and continues today. Dissecting the statements and work of contemporary scientists studying human biodiversity, most of whom claim to be just following the data, Saini shows us how, again and again, science is retrofitted to accommodate race. Even as our understanding of highly complex traits like intelligence, and the complicated effect of environmental influences on human beings, from the molecular level on up, grows, the hope of finding simple genetic differences between "races"--to explain differing rates of disease, to explain poverty or test scores or to justify cultural assumptions--stubbornly persists. At a time when racialized nationalisms are a resurgent threat throughout the world, Superior is a powerful reminder that biologically, we are all far more alike than different.

Superkondensatoren: Schnelle Energiespeicher für hohe elektrische Leistungen

by Rudolf Holze

Konventionelle Kondensatoren sind für ihre Fähigkeit, hohe Ströme aufnehmen und abgeben zu können, bekannt.

Supermathematics and its Applications in Statistical Physics

by Franz Wegner

This text presents the mathematical concepts of Grassmannvariables and the method of supersymmetry to a broad audience of physicistsinterested in applying these tools to disordered and critical systems, as wellas related topics in statistical physics. Based on many courses and seminarsheld by the author, one of the pioneers in this field, the reader is given asystematic and tutorial introduction to the subject matter. The algebra and analysis of Grassmann variables ispresented in part I. The mathematics of these variables is applied to a randommatrix model, path integrals for fermions, dimer models and the Ising model intwo dimensions. Supermathematics - the use of commuting and anticommutingvariables on an equal footing - is the subject of part II. The properties ofsupervectors and supermatrices, which contain both commuting and Grassmanncomponents, are treated in great detail, including the derivation of integraltheorems. In part III, supersymmetric physical models are considered. Whilesupersymmetry was first introduced in elementary particle physics as exactsymmetry between bosons and fermions, the formal introduction of anticommutingspacetime components, can be extended to problems of statistical physics, and,since it connects states with equal energies, has also found its way intoquantum mechanics. Several models are considered in the applications, afterwhich the representation of the random matrix model by the nonlinearsigma-model, the determination of the density of states and the levelcorrelation are derived. Eventually, the mobility edge behavior is discussedand a short account of the ten symmetry classes of disorder, two-dimensionaldisordered models, and superbosonization is given.

Supernatural: Meetings with the Ancient Teachers of Mankind

by Graham Hancock

Less than fifty thousand years ago mankind had no art, no religion, no sophisticated symbolism, no innovative thinking. Then, in a dramatic and electrifying change, described by scientists as "the greatest riddle in human history," all the skills and qualities that we value most highly in ourselves appeared already fully formed, as though bestowed on us by hidden powers. In this book, the author sets out to investigate this mysterious "beforeandafter moment" and to discover the truth about the influences that gave birth to the modern human mind. His quest takes him on a detective journey from the stunningly beautiful painted caves of prehistoric France, Spain, and Italy to rock shelters in the mountains of South Africa, where he finds extraordinary Stone Age art. He uncovers clues that lead him to the depths of the Amazon rainforest to drink the powerful hallucinogen Ayahuasca with shamans, whose paintings contain images of "supernatural beings" identical to the animalhuman hybrids depicted in prehistoric caves. Hallucinogens such as mescaline also produce visionary encounters with exactly the same beings. Scientists at the cutting edge of consciousness research have begun to consider the possibility that such hallucinations may be real perceptions of other "dimensions." Could the "supernaturals" first depicted in the painted caves be the ancient teachers of mankind? Could it be that human evolution is not just the "meaningless" process that Darwin identified, but something more purposive and intelligent that we have barely begun to understand?
