Nobel Laureate Steven Weinberg continues his masterly exposition of quantum field theory. This third volume of The Quantum Theory of Fields presents a self-contained, up-to-date and comprehensive introduction to supersymmetry, a highly active area of theoretical physics that is likely to be at the center of future progress in the physics of elementary particles and gravitation. The text introduces and explains a broad range of topics, including supersymmetric algebras, supersymmetric field theories, extended supersymmetry, supergraphs, nonperturbative results, theories of supersymmetry in higher dimensions, and supergravity. A thorough review is given of the phenomenological implications of supersymmetry, including theories of both gauge and gravitationally-mediated supersymmetry breaking. Also provided is an introduction to mathematical techniques, based on holomorphy and duality, that have proved so fruitful in recent developments. This book contains much material not found in other books on supersymmetry, some of it published here for the first time. Problems are included.
Quantum Theory is the most revolutionary discovery in physics since Newton. This book gives a lucid, exciting, and accessible account of the surprising and counterintuitive ideas that shape our understanding of the sub-atomic world. It does not disguise the problems of interpretation that still remain unsettled 75 years after the initial discoveries. The main text makes no use of equations, but there is a Mathematical Appendix for those desiring stronger fare. Uncertainty, probabilistic physics, complementarity, the problematic character of measurement, and decoherence are among the many topics discussed.
"As someone who's both a scientist and an Anglican priest, I've been concerned with trying to understand how the scientific and religious views of the world relate to each other. Do we have to choose between them or are they, instead, complementary understandings that, seen together, give us a fuller picture than either on their own would provide? I find the best way to sort out what I really think is to try to write it down. The late Bishop John Robinson once said to me that he couldn't think without a pen in his hand, and I knew exactly what he meant. In consequence, I've written six books on different aspects of this question. Now I've decided it would be useful to try to provide an overview that surveyed the whole scene, rather than concentrating on this or that particular feature of it, as my earlier books have done. At the same time, it gives me the chance to try to set out the main lines of the argument without having to reproduce all the detailed discussion that I've gone into previously. I do a fair amount of speaking on these issues, and I always greatly enjoy the discussion period that normally follows a lecture. This experience has given me some idea of what the main questions are in people's minds, and what are the most helpful insights to offer them. I actually think that we need both science and religion, and that they have many important things to say to each other. I hope this short book may help others to share in such a conversation."
It looks like a bear, but isn't one. It climbs trees as easily as a monkey- but isn't a monkey, either. It has a belly pocket like a kangaroo, but what's a kangaroo doing up a tree? Meet the amazing Matschie's tree kangaroo, who makes its home in the ancient trees of Papua New Guinea's cloud forest. And meet the amazing scientists who track these elusive animals.

Modern industrial society is an experiment with a brief past and an uncertain future. In less than two centuries, technology has transformed the globe and given the human race the power to realize its highest ideals or destroy itself.
In this new edition of Questioning the Millennium, best-selling author Stephen Jay Gould applies his wit and erudition to one of today's most pressing subjects: the significance of the millennium. In 1950 at age eight, prompted by an issue of Life magazine marking the century's midpoint, Stephen Jay Gould started thinking about the approaching turn of the millennium. In this beautiful inquiry into time and its milestones, he shares his interest and insights with his readers. Refreshingly reasoned and absorbing, the book asks and answers the three major questions that define the approaching calendrical event. First, what exactly is this concept of a millennium and how has its meaning shifted? How did the name for a future thousand-year reign of Jesus Christ on earth get transferred to the passage of a secular period of a thousand years in current human history? When does the new millennium really begin: January 1, 2000, or January 1, 2001? (Although seemingly trivial, the debate over this issue tells an intriguing story about the cultural history of the twentieth century.) And why must our calendars be so complex, leading to our search for arbitrary regularity, including a fascination with millennia? This revised edition begins with a new and extensive preface on a key subject not treated in the original version.As always, Gould brings into his essays a wide range of compelling historical and scientific fact, including a brief history of millennial fevers, calendrical traditions, and idiosyncrasies from around the world; the story of a sixth-century monk whose errors in chronology plague us even today; and the heroism of a young autistic man who has developed the extraordinary ability to calculate dates deep into the past and the future. Ranging over a wide terrain of phenomena--from the arbitrary regularities of human calendars to the unpredictability of nature, from the vagaries of pop culture to the birth of Christ--Stephen Jay Gould holds up the mirror to our millennial passions to reveal our foibles, absurdities, and uniqueness--in other words, our humanity.
With the emergence of the new field of evolutionary developmental biology we are witnessing a renaissance of Darwin's insights 150 years after his Origin of Species. Thus far, the exciting findings from "evo-devo" have only been trickling into college courses and into the domain of non-specialists. With its focus on the human organism, Quirks of Human Anatomy opens the floodgates by stating the arguments of evo-devo in plain English, and by offering a cornucopia of interesting case studies and examples. Its didactic value is enhanced by 24 schematic diagrams that integrate a host of disparate observations, by its Socratic question-and-answer format, and by its unprecedented compilation of the literature. By framing the "hows" of development in terms of the "whys" of evolution, it lets readers probe the deepest questions of biology. Readers will find the book not only educational but also enjoyable, as it revels in the fun of scientific exploration.
* Is there really such a thing as a blue moon?* What time is it at the North Pole?* Why don't woodpeckers get concussed?* Why don't snorers wake themselves with the racket they make?* Do insects sleep?These are just a few of the intriguing questions asked and answered in The Quirks & Quarks Question Book, the first question and answer book to come out of CBC Radio's enormously popular weekly science program. Quirks & Quarks producers have combed through ten years' worth of archives to find the most puzzling questions - or the most fascinating answers to apparently simple questions - from the program's Question of the Week segment or its once-a-season all-question show. The scientists and researchers with the answers (many of whom updated their answers for the book in light of new research findings) come from all scientific disciplines and all parts of the country. What they have in common is their ability to explain serious, complicated science in layman's terms. This isn't science made simple, but science made understandable.Introduced by the program's host for the past ten years, the genial and ever-curious Bob McDonald, The Quirks & Quarks Question Book has the answers to questions you may never have thought to ask (why does Uranus spin on a different axis from all the other planets in our solar system?) or have spent idle time wondering about (why is there a calm before a storm?). Whether you want to know if you can sweat while you swim or what the view would be like if you could travel at the speed of light, or perhaps you just want to peruse the latest scientific thinking on a wide range of topics, The Quirks & Quarks Question Book has the answer.Quirks & Quarks has been keeping Canadians up to date on the world of science for more than 25 years. Every week, the program presents the people behind the latest discoveries in the physical and natural sciences. The program also examines the political, social, environmental, and ethical implications of new developments in science and technology. Over its lifetime, Quirks & Quarks has won more than 40 national and international awards for science journalism.From the Trade Paperback edition.

Leading scholars from a range of disciplines, including law, biology, sociology, history, anthropology, and psychology, examine the impact of modern genetics on the concept of race. Does mapping the human genome reconstitute a scientific rationale for long-discredited racial categories? Contributors trace the interplay between genetics and race in forensic DNA databanks, the biology of intelligence, DNA ancestry markers, and racialized medicine. Each essay explores commonly held and unexamined assumptions and misperceptions about race in both science and popular culture. Divided into six major categories, the collection begins with the historical origins and current uses of the concept of "race" in science. It follows with an analysis of the role of race in DNA databanks and its reflection of racial disparities in the criminal justice system. Essays then consider the rise of recreational genetics in the form of for-profit testing of genetic ancestry and the introduction of racialized medicine, specifically through an FDA-approved heart drug called BiDil, marketed to African American men. Concluding sections discuss the contradictions between our scientific and cultural understandings of race and the continuing significance of race in educational and criminal justice policy, not to mention the ongoing project of a society that has no use for racial stereotypes.

With her controversial book, Silent Spring, Rachel Carson changed the way we look at our planet.
Gold Award Winner for Philosophy in the 2003 ForeWord Magazine Book of the Year Awards Professor Grue is dead (or is he?). When graduate student/sleuth Miranda Sharpe discovers him slumped over his keyboard, she does the sensible thing--she grabs her dissertation and runs. Little does she suspect that soon she will be probing the heart of two mysteries, trying to discover what happened to Max Grue, and trying to solve the profound neurophilosophical problem of consciousness. Radiant Cool may be the first novel of ideas that actually breaks new theoretical ground, as Dan Lloyd uses a neo-noir (neuro-noir?), hard-boiled framework to propose a new theory of consciousness. In the course of her sleuthing, Miranda encounters characters who share her urgency to get to the bottom of the mystery of consciousness, although not always with the most innocent motives. Who holds the key to Max Grue's ultimate vision? Is it the computer-inspired pop psychologist talk-show host? The video-gaming geek with a passion for artificial neural networks? The Russian multi-dimensional data detective, or the sophisticated neuroscientist with the big book contract? Ultimately Miranda teams up with the author's fictional alter ego, "Dan Lloyd," and together they build on the phenomenological theories of philosopher Edmund Husserl (1859-1938) to construct testable hypotheses about the implementation of consciousness in the brain. Will the clues of phenomenology and neuroscience converge in time to avert a catastrophe? (The dramatic ending cannot be revealed here.) Outside the fictional world of the novel, Dan Lloyd (the author) appends a lengthy afterword, explaining the proposed theory of consciousness in more scholarly form. Radiant Coolis a real metaphysical thriller--based in current philosophy of mind--and a genuine scientific detective story--revealing a new interpretation of functional brain imaging. With its ingenious plot and its novel theory, Radiant Cool will be enjoyed in the classroom and the study for its entertaining presentation of phenomenology, neural networks, and brain imaging; but, most importantly, it will find its place as a groundbreaking theory of consciousness.
In the first edition of Radical Ecology--the now classic examination major philosophical, ethical, scientific, and economic roots of environmental problems--Carolyn Merchant responded to the profound awareness of environmental crisis which prevailed in the closing decade of the twentieth century. In this provocative and readable study, Merchant examines the ways that radical ecologists can transform science and society in order to sustain life on this planet. Now in this second edition, Merchant continues to emphasize how laws, regulations and scientific research alone cannot reverse the spread of pollution or restore our dwindling resources. Merchant argues that in order to maintain a livable world, we must formulate new social, economic, scientific, and spiritual approaches that will fundamentally transform human relationships with nature. She analyzes the revolutionary ideas of visionary ecologists for a new economy, society, science, and religion, and examines their efforts to bring environmental problems to the attention of the public. This new edition features a new Introduction from the author, a thorough updating of chapters, and two entirely new chapters on recent global movements and globalization and the environment. It is a timely update that will give students everything they need to know on the most recent philosophical positions and social movements that characterize the radical ecology spectrum.
Radical Evolution: The Promise and Peril of Enhancing Our Minds, Our Bodies - and What It Means to Be Humanby Joel Garreau
Bestselling author Joel Garreau, a reporter and editor for the Washington Post, shows us that we are at an inflection point in history. As you read this, we are engineering the next stage of human evolution. Through advances in genetic, robotic, information and nanotechnologies, we are altering our minds, our memories, our metabolisms, our personalities, our progeny-and perhaps our very souls. Taking us behind the scenes with today's foremost researchers and pioneers, Garreau reveals that the super powers of our comic-book heroes already exist, or are in development in hospitals, labs, and research facilities around the country -- from the revved up reflexes and speed of Spider-Man and Superman, to the enhanced mental acuity and memory capabilities of an advanced species. Over the next fifteen years, Garreau makes clear, these enhancements will become part of our everyday lives. Where will they lead us? To heaven -- where technology's promise to make us smarter, vanquish illness and extend our lives is the answer to our prayers? Or will they lead us, as some argue, to hell -- where unrestrained technology brings about the ultimate destruction of our entire species? With the help and insights of the gifted thinkers and scientists who are making what has previously been thought of as science fiction a reality, Garreau explores how these developments, in our lifetime, will affect everything from the way we date to the way we work, from how we think and act to how we fall in love. It is a book about what our world is becoming today, not fifty years out. As Garreau cautions, it is only by anticipating the future that we can hope to shape it.
Imagine you are first in line at a potluck buffet. The spread includes not just food and water, but all the materials needed for shelter, clothing, healthcare, and education. How do you know how much to take? How much is enough to leave for your neighbours behind you -- not just the six billion people, but the wildlife, and the as-yet-unborn? In the face of looming ecological disaster, many people feel the need to change their own lifestyles as a tangible way of transforming our unsustainable culture. Radical Simplicity is the first book that guides the reader to a personal sustainability goal, then offers a process to monitor progress to a lifestyle that is equitable amongst all people, species, and generations. Combining lyrical narrative, compassionate advocacy and absorbing science, Radical Simplicity is a practical, personal answer to 21st century challenges that will appeal as much to Cultural Creatives and students as to spiritual seekers, policy makers and sustainability professionals.
This book describes the beginnings of radio - the mystery of unseen waves and the people experimenting with this new process. The book was handed down to me by my Grandfather who served in the Spanish-American War and then settled in San Francisco in 1905; just in time for the earthquake. The last few pages are ads complete with 1923 prices. One is for a book - Sergeant York and His People- later Gary Cooper stared in the movie - Sergeant York.
Growing up in suburban Detroit, David Hahn was fascinated by science. While he was working on his Atomic Energy badge for the Boy Scouts, David's obsessive attention turned to nuclear energy. Throwing caution to the wind, he plunged into a new project: building a model nuclear reactor in his backyard garden shed. Posing as a physics professor, David solicited information on reactor design from the U. S. government and from industry experts. Following blueprints he found in an outdated physics textbook, David cobbled together a crude device that threw off toxic levels of radiation. His wholly unsupervised project finally sparked an environmental emergency that put his town's forty thousand suburbanites at risk. The EPA ended up burying his lab at a radioactive dumpsite in Utah. This offbeat account of ambition and, ultimately, hubris has the narrative energy of a first-rate thriller.

From the Book jacket: A conservation officer discovers a wounded bald eagle, lying in a ditch by the side of the road. The bird has been shot in the left wing. Unable to fly after food, it is close to death. But the officer knows just what to do. Within a few hours, a new patient is undergoing emergency surgery at the world-renowned Gabbert Raptor Center, located at the University of Minnesota. Here is an unusual behind-the-scenes exploration of a rehabilitation center for injured birds of prey. Crisp, arresting photos and an engaging text follow the story of a raptor's recovery-from admission, X ray, and surgery through recuperation, flight therapy, and release. Young nature lovers will enjoy this fascinating introduction to the work of the center's veterinary and volunteer staff and to the raptors themselves-among the most beautiful, remarkable, and, in some cases, threatened of wild creatures. This file should make an excellent embossed braille copy.
