A Broader View of Relativity shows that there is still new life in old physics. The book examines the historical context and theoretical underpinnings of Einstein''s theory of special relativity and describes Broad Relativity, a generalized theory of coordinate transformations between inertial reference frames that includes Einstein''s special relativity as a special case. It shows how the principle of relativity is compatible with multiple concepts of physical time and how these different procedures for clock synchronization can be useful for thinking about different physical problems, including many-body systems and the development of a Lorentz-invariant thermodynamics. Broad relativity also provides new answers to old questions such as the necessity of postulating the constancy of the speed of light and the viability of Reichenbach''s general concept of time. The book also draws on the idea of limiting-four-dimensional symmetry to describe coordinate transformations and the physics of particles and fields in non-inertial frames, particularly those with constant linear accelerations. This new edition expands the discussion on the role that human conventions and unit systems have played in the historical development of relativity theories and includes new results on the implications of broad relativity for clarifying the status of constants that are truly fundamental and inherent properties of our universe.

A Nobel Prize–winning physicist’s “funny, clever, entertaining” account of the history of particle physics and the hunt for a Higgs boson (Library Journal). In this extraordinarily accessible and witty book, Leon Lederman—“the most engaging physicist since the late, much-missed Richard Feynman” (San Francisco Examiner)—offers a fascinating tour that takes us from the Greeks’ earliest scientific observations through Einstein and beyond in an inspiring celebration of human curiosity. It ends with the quest for the Higgs boson, nicknamed the God Particle, which scientists hypothesize will help unlock the last secrets of the subatomic universe. This is not only an enlightening journey through baryons and hadrons and leptons and electrons—it also “may be the funniest book about physics ever written” (The Dallas Morning News). “One of the clearest, most enjoyable new science books in years . . . explains the entire history of physics and cosmology. En route, you’ll laugh so hard you won’t realize how much you are learning.” —San Francisco Examiner “The story of the search for the ultimate constituents of matter has been told many times before, but never with more verve and wit. . . . His hilarious account of how he helped persuade President Reagan to approve the construction of the Super Collider is itself worth the price of the book.” —Los Angeles Times
It’s a good story: we are made of matter like that we also find in the stars. Essential to our planet’s existence, the Sun—our nearest star––is also the most fascinating object humans have ever adored, literally the difference between day and night. But getting beyond these basic perceptions requires scientific understanding. What, for instance, is the sun made of? Why does it burn so brightly? How long will it last? This book not only answers these questions but also tells the story of how we came to know—not merely behold—the grandest entity in our sky. Leon Golub and Jay M. Pasachoff offer an engaging and informative account of solar science and its history, drawing on centuries of study by solar astronomers who have looked to the Sun not only to learn about our own solar system but also about what lies in the distant wilderness of faintly glimmering stars. They skim along the surface of the Sun, which is decorated with sunspots, discussing these fascinating magnetic aberrations and the roughly eleven-year cycles they abide. They follow seismic waves into the interior of the Sun and its unending nuclear fusion. They show us what is unveiled in solar eclipses and what new views and knowledge our space exploration has afforded us. They brave solar weather, and they trace the arcs of radiation and particles whose effects we can see on earth in phenomena such as the northern and southern lights. Glowing with a wide assortment of astonishing images, this beautifully illustrated guide will delight everyone, from those who know what a coronagraph is to those who simply like to step out on a bright day, close their eyes, and feel the Sun’s warmth upon their skin.
Readers will learn all about gravity, friction, and more through explanations using both familiar and extraordinary situations. Bright, colorful photographs will keep readers engaged as the forces are shown at work in exciting ways, such as in skydiving, rollercoaster construction, and super-fast cars.
The throngs at Woodstock, Jane Fonda in Hanoi, I Have a Dream, burning draft cards, fire in the streets--these images of the 1960s are still very much alive today. What happened to the people and principles that dominated that decade? Which leaders from those turbulent years had the most lasting effect on our lives today? How well have the principles for which those leaders fought so strongly withstood the test of time? This thought-provoking biographical dictionary allows the reader to study the leaders, both conservative and liberal, their ideals, and their enduring influence. With major sections on racial democracy, peace and freedom, sexuality and gender, the environment, radical culture, and visions of alternative societies, Leaders from the 1960s includes entries on a wide selection of nationally prominent activists of the 1960s. In addition to those who dominated only the sixties, the volume includes earlier activists who came into prominence in the 1960s and activists of the era who came into prominence since the 1960s. Each entry provides a biographical sketch, but the focus of the entries is on the person's basic concepts or the essence of his or her work and the public response it generated. Included are extensive bibliographies on the individuals and the period.
This book charts the life and work of the neurophysiologist G. G. J. Rademaker against the background of flourishing early-20th-century Dutch clinical research, describing the rise and fall of the branch of experimental neurophysiology of which Rademaker was a master.
Reveals the Hermetic underpinnings of modern scientific theories • Offers a full reconsideration of the history of science from Newton to the present day as well as a Platonic-Hermetic perspective on modern technology • Examines Hermetic resonances among the ideas of Gurdjieff, Robert Fludd, Marsilio Ficino, and cybernetics; Einstein and the Tibetan Bardo; Neoplatonism and artificial intelligence; and Rosicrucianism and the internet • Shows how Hermetic doctrine is at the heart of what modern physics is now rediscovering: that consciousness permeates everything Contemporary scientific disciplines such as chaos and complexity theory, artificial intelligence, and cognitive science treat themselves as new fields of inquiry, but many of these ideas can be traced back to Hermeticism, the European intellectual tradition sparked by the rediscovery of the Corpus Hermeticum and Platonic texts in the 15th century. Building a map of the progression of scientific thought across centuries and continents, Leon Marvell examines the ancient roots of Hermeticism, its rise during the Renaissance, and its suppression during the scientific revolution of the Enlightenment. He reveals how three main Hermetic ideas--the divine spark within each individual, the subtle body, and the anima mundi or world soul--have continually emerged at the cutting edge of science and philosophy throughout the ages because these ideas represent universal truths recognized by each era of human civilization. Marvell examines Hermetic resonances among the ideas of Gurdjieff, Robert Fludd, Marsilio Ficino, and cybernetic theory; Einstein and the Tibetan Bardo; and Neoplatonism and the work of AI scientist Christopher Langton. He reveals how the Rosicrucian description of the Invisible College also describes the instant availability of knowledge via the Internet, and he shows how Hermetic thought is at the heart of what modern physics is rediscovering: that consciousness permeates everything and the universe cannot be reduced to the random play of matter. Offering a full reconsideration of the history of science from Newton to the present day as well as a Platonic-Hermetic perspective on modern technology, Marvell reveals the pattern that connects the sciences, philosophy, and ancient knowledge and opens a potentially rich field of inquiry for 21st-century science.
Two leading physicists discuss the importance of the Higgs Boson, the future of particle physics, and the mysteries of the universe yet to be unraveled. On July 4, 2012, the long-sought Higgs Boson--aka "the God Particle"--was discovered at the world's largest particle accelerator, the LHC, in Geneva, Switzerland. On March 14, 2013, physicists at CERN confirmed it. This elusive subatomic particle forms a field that permeates the entire universe, creating the masses of the elementary particles that are the basic building blocks of everything in the known world--from viruses to elephants, from atoms to quasars. Starting where Nobel Laureate Leon Lederman's bestseller The God Particle left off, this incisive new book explains what's next. Lederman and Hill discuss key questions that will occupy physicists for years to come:* Why were scientists convinced that something like the "God Particle" had to exist?* What new particles, forces, and laws of physics lie beyond the "God Particle"?* What powerful new accelerators are now needed for the US to recapture a leadership role in science and to reach "beyond the God Particle," such as Fermilab's planned Project-X and the Muon Collider? Using thoughtful, witty, everyday language, the authors show how all of these intriguing questions are leading scientists ever deeper into the fabric of nature. Readers of The God Particle will not want to miss this important sequel.

Woodson published the first issue of Journal of Negro History--all on January 1 of their respective years. This is a day-by-day guide to African American achievements and those happenings that have affected their history, including the birth dates of many significant men and women. The people and events are drawn from all walks of life: politics and government, civil rights, sports, entertainment, journalism, court decisions, writers and others. The work is fully indexed.
The vast genealogical records of Texas were created by successive governments over a period of almost 200 years. From the earliest recorded land grants by the Spanish and the Mexicans, to the grants, deeds, and patents of the Republic and State of Texas, the titles to the lands of Texas have remained intact and have passed down by will or deed to the present. These records and masses of other genealogical records are available to the researcher provided he/she knows how and where to find them. This remarkable book holds the key. Texas covers a lot of ground, but this guide cuts it right down to size and makes record searching fast and convenient. In text and maps it provides detailed information on the legal and historical background of the state, the origin of each county, the location of the records for each portion of the county before it was organized into its present boundaries, and the specific records available in the various county courthouses, the Texas State Library, the Texas State Archives, and the Texas General Land Office. In addition, it provides information on the original colonies and districts of Texas, a list of Spanish terms used in land grants and deeds, a list of Texas libraries with resources for genealogical research, and a bibliography.
One of the basic tenets of science is that deterministic systems are completely predictable-given the initial condition and the equations describing a system, the behavior of the system can be predicted 1 for all time. The discovery of chaotic systems has eliminated this viewpoint. Simply put, a chaotic system is a deterministic system that exhibits random behavior. Though identified as a robust phenomenon only twenty years ago, chaos has almost certainly been encountered by scientists and engi neers many times during the last century only to be dismissed as physical noise. Chaos is such a wide-spread phenomenon that it has now been reported in virtually every scientific discipline: astronomy, biology, biophysics, chemistry, engineering, geology, mathematics, medicine, meteorology, plasmas, physics, and even the social sci ences. It is no coincidence that during the same two decades in which chaos has grown into an independent field of research, computers have permeated society. It is, in fact, the wide availability of inex pensive computing power that has spurred much of the research in chaotic dynamics. The reason is simple: the computer can calculate a solution of a nonlinear system. This is no small feat. Unlike lin ear systems, where closed-form solutions can be written in terms of the system's eigenvalues and eigenvectors, few nonlinear systems and virtually no chaotic systems possess closed-form solutions.
The Physics of Music and Color deals with two subjects, music and color - sound and light in the physically objective sense - in a single volume. The basic underlying physical principles of the two subjects overlap greatly: both music and color are manifestations of wave phenomena, and commonalities exist as to the production, transmission, and detection of sound and light. This book aids readers in studying both subjects, which involve nearly the entire gamut of the fundamental laws of classical as well as modern physics. Where traditional introductory physics and courses are styled so that the basic principles are introduced first and are then applied wherever possible, this book is based on a motivational approach: it introduces a subject by demonstrating a set of related phenomena, challenging readers by calling for a physical basis for what is observed. The Physics of Music and Color is written at level suitable for college students without any scientific background, requiring only simple algebra and a passing familiarity with trigonometry. It contains numerous problems at the end of each chapter that help the reader to fully grasp the subject.
Quantum theory is the bedrock of contemporary physics and the basis of understanding matter in its tiniest dimensions and the vast universe as a whole. But for many, the theory remains an impenetrable enigma. Now, two physicists seek to remedy this situation by both drawing on their scientific expertise and their talent for communicating science to the general reader. In this lucid, informative book, designed for the curious, Lederman and Hill make the seemingly daunting subject of quantum physics accessible, appealing, and exciting. Their story is partly historical, covering the many "Eureka" moments when great scientists-Max Planck, Albert Einstein, Niels Bohr, Werner Heisenberg, Erwin Schrödinger, and others-struggled to come to grips with the bizarre realities that quantum research revealed. Although their findings were indisputably proven in experiments, they were so strange and counterintuitive that Einstein refused to accept quantum theory, despite its great success. The authors explain the many strange and even eerie aspects of quantum reality at the subatomic level, from "particles" that can be many places simultaneously and sometimes act more like waves, to the effect that a human can have on their movements by just observing them! Finally, the authors delve into quantum physics' latest and perhaps most breathtaking offshoots-field theory and string theory. The intricacies and ramifications of these two theories will give the reader much to ponder. In addition, the authors describe the diverse applications of quantum theory in its almost countless forms of modern technology throughout the world. Using eloquent analogies and illustrative examples, Quantum Physics for Poets renders even the most profound reaches of quantum theory understandable and something for us all to savor.

When scientists peer through a telescope at the distant stars in outer space or use a particle-accelerator to analyze the smallest components of matter, they discover that the same laws of physics govern the whole universe at all times and all places. Physicists call the eternal, ubiquitous constancy of the laws of physics symmetry. Symmetry is the basic underlying principle that defines the laws of nature and hence controls the universe. This all-important insight is one of the great conceptual breakthroughs in modern physics and is the basis of contemporary efforts to discover a grand unified theory to explain all the laws of physics. Nobel Laureate Leon M. Lederman and physicist Christopher T. Hill explain the supremely elegant concept of symmetry and all its profound ramifications to life on Earth and the universe at large in this eloquent, accessible popular science book. They not only clearly describe concepts normally reserved only for physicists and mathematicians, but they also instill an appreciation for the profound beauty of the universe’s inherent design. Central to the story of symmetry is an obscure, unpretentious, but extremely gifted German mathematician named Emmy Noether. Though still little known to the world, she impressed no less a scientist than Albert Einstein, who praised her "penetrating mathematical thinking." In some of her earliest work she proved that the law of the conservation of energy was connected to the idea of symmetry and thus laid the mathematical groundwork for what may be the most important concept of modern physics. Lederman and Hill reveal concepts about the universe, based on Noether’s work, that are largely unknown to the public and have wide-reaching implications in connection with the Big Bang, Einstein’s theory of relativity, quantum mechanics, and many other areas of physics. Through ingenious analogies and illustrations, they bring these astounding notions to life. This book will open your eyes to a universe you never knew existed.

Social Work and Science in the 21st Century enhances the inclusion of natural science concepts and knowledge into social work education and practice. The book highlights basic scientific theories and ideas in a broad array of natural science fields, including chemistry, physics, astronomy, geometry, numbers, and big data. A number of chapters focus on how knowledge from the natural sciences can enhance social work practice in areas as diverse as medicine, substance abuse, mental health, and intellectual and developmental disabilities, while other chapters on water, human geography, climate change, execution and the death penalty, and the life cycle are designed to highlight the natural science behind social issues. The information presented in the book is complex enough to spark the reader's continued interest in knowing more about the natural sciences, but basic enough to allow readers with limited understanding of the natural sciences--at both the bachelor's and master's levels--to feel comfortable exploring its contents.
This book presents a new approach to the study of physical nonlinear circuits and advanced computing architectures with memristor devices. Such a unified approach to memristor theory has never been systematically presented in book form. After giving an introduction on memristor-based nonlinear dynamical circuits (e.g., periodic/chaotic oscillators) and their use as basic computing analogue elements, the authors delve into the nonlinear dynamical properties of circuits and systems with memristors and present the flux-charge analysis, a novel method for analyzing the nonlinear dynamics starting from writing Kirchhoff laws and constitutive relations of memristor circuit elements in the flux-charge domain. This analysis method reveals new peculiar and intriguing nonlinear phenomena in memristor circuits, such as the coexistence of different nonlinear dynamical behaviors, extreme multistability and bifurcations without parameters. The book also describes how arrays of memristor-based nonlinear oscillators and locally-coupled neural networks can be applied in the field of analog computing architectures, for example for pattern recognition. The book will be of interest to scientists and engineers involved in the conceptual design of physical memristor devices and systems, mathematical and circuit models of physical processes, circuits and networks design, system engineering, or data processing and system analysis.
In the late nineteenth century, David Paul von Hansemann coined phrases that have remained the basis of descriptive terms concerning the microscopical appearances of tumors ever since, yet his work is rarely mentioned today. This book presents translations of all the relevant German texts and analyses the background and context of Hansemann's theories. It shows that some of Hansemann’s ideas may still be relevant to cancer research today.

Where Eliot's poetry is dominated by cultural, religious, and philosophical anxiety, Stevens' is bright, witty, and playful - and commonly dismissed as superficial. Surette demonstrates the seriousness of Stevens' life-long engagement with the modern dilemma of disbelief, showing that he, like Eliot, rejected the Humanist resolution. Surette proceeds by juxtaposing the two poets' responses in poetry and prose to the same texts and events: Marianne Moore's poetry, the Great War, Humanists and anti-Humanists, the Franco-Mexican Humanist Ramon Fernandez, Pure Poetry, and, finally, the gathering war clouds of the late 1930s.
