Taschenbuch. Condizione: Neu. Neuware -From novels and short stories to television and film, popular media has made a cottage industry of predicting the end of the world will be caused by particle accelerators. Rather than allay such fears, public pronouncements by particle scientists themselves often unwittingly fan the flames of hysteria.This book surveys media depictions of particle accelerator physics and the perceived dangers these experiments pose. In addition, it describes the role of scientists in propagating such fears and misconceptions, offering as a conclusion ways in which the scientific community could successfully allay such misplaced fears through more effective communication strategies.The book is aimed at the general reader interested in separating fact from fiction in the field of high-energy physics, at science educators and communicators, and, last but not least, at all scientists concerned about these issues.About the AuthorKristine M Larsen holds a Ph.D. in Physics and is currently a professor at Central Connecticut State University, New Britain, CT, in the Geological Sciences Department.

Taschenbuch. Condizione: Neu. Neuware -Für moderne Ingenieurdisziplinen wie die Mechatronik werden Modellbildung und Simulation technischer Systeme immer wichtiger. Klassische Methoden sind wenig intuitiv, mathematiklastig und nicht objektorientiert. Den Bondgraphen kann man ohne Kenntnis des mathematischen Modells direkt in ein grafisches Simulationssystem eingeben, das automatisch das mathematische Modell generiert. Die Objektorientierung unterstützt sehr gut die Anschaulichkeit des Modells und erleichtert das Systemverständnis des Anwenders. Insbesondere in der Mechatronik, in der häufig Multidomänen-Systeme zu modellieren sind, hat diese Methode daher große Vorteile. 73 pp. Deutsch.

Buch. Condizione: Neu. Neuware -This open access book chronicles the rise of a new scientific paradigm offering novel insights into the age-old enigmas of existence. Over 300 years ago, the human mind discovered the machine code of reality: mathematics. By utilizing abstract thought systems, humans began to decode the workings of the cosmos. From this understanding, the current scientific paradigm emerged, ultimately discovering the gift of technology. Today, however, our island of knowledge is surrounded by ever longer shores of ignorance. Science appears to have hit a dead end when confronted with the nature of reality and consciousness. In this fascinating and accessible volume, James Glattfelder explores a radical paradigm shift uncovering the ontology of reality. It is found to be information-theoretic and participatory, yielding a computational and programmable universe.

Buch. Condizione: Neu. Neuware -This open access book is a systematic update of the philosophical and scientific foundations of the biopsychosocial model of health, disease and healthcare. First proposed by George Engel 40 years ago, the Biopsychosocial Model is much cited in healthcare settings worldwide, but has been increasingly criticised for being vague, lacking in content, and in need of reworking in the light of recent developments. The book confronts the rapid changes to psychological science, neuroscience, healthcare, and philosophy that have occurred since the model was first proposed and addresses key issues such as the model¿s scientific basis, clinical utility, and philosophical coherence.The authors conceptualise biology and the psychosocial as in the same ontological space, interlinked by systems of communication-based regulatory control which constitute a new kind of causation. These are distinguished from physical and chemical laws, most clearly because they can break down, thus providing the basis for difference between health and disease. This work offers an urgent update to the model¿s scientific and philosophical foundations, providing a new and coherent account of causal interactions between the biological, the psychological and social.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 164 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -People are used to seeing ¿fake physics¿ in science fiction ¿ concepts like faster-than-light travel, antigravity and time travel to name a few. The fiction label ought to be a giveaway, but some SF writers ¿ especially those with a background in professional science ¿ are so adept at ¿technobabble¿ that it can be difficult to work out what is fake and what is real. To confuse matters further, Isaac Asimov¿s 1948 piece about the fictitious time-travelling substance thiotimoline was written, not as a short story, but in the form of a spoof research paper.The boundaries between fact and fiction can also be blurred by physicists themselves - sometimes unintentionally, sometimes with tongue-in-cheek, sometimes to satirize perceived weaknesses in research practices. Examples range from hoaxes aimed at exposing poor editorial standards in academic publications, through ¿thought experiments¿ that sound like the plot of a sci-fi movie to April Fools¿ jokes. Even the latter may carry a serious message, whether about the sociology of science or poking fun at legitimate but far-out scientific hypotheses.This entertaining book is a joyous romp exploring the whole spectrum of fake physics ¿ from science to fiction and back again.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 180 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Advances in artificial intelligence, sensor computing, robotics, and mobile systems are making autonomous systems a reality. At the same time, the influence of edge computing is leading to more distributed architectures incorporating more autonomous elements. The flow of information is critical in such environments, but the real time, distributed nature of the system components complicates the data protection mechanisms. Policy-based management has proven useful in simplifying the complexity of management in domains like networking, security, and storage; it is expected that many of those benefits would carry over to the task of managing big data and autonomous systems.This book aims at providing an overview of recent work and identifying challenges related to the design of policy-based approaches for managing big data and autonomous systems. An important new direction explored in the book is to make the major elements of the system self-describing and self-managing. This would lead to architectures where policy mechanisms are tightly coupled with the system elements. In such integrated architectures, we need new models for information assurance, traceability of information, and better provenance on information flows. In addition when dealing with devices with actuation capabilities and, thus, being able to make changes to physical spaces, safety is critical. With an emphasis on policy-based mechanisms for governance of data security and privacy, and for safety assurance, the papers in this volume follow three broad themes: foundational principles and use-cases for the autonomous generation of policies; safe autonomy; policies and autonomy in federated environments. 227 pp. Englisch.

Buch. Condizione: Neu. Neuware -In the early morning hours of Feb. 1, 2016, Karl Gustafson became instinctively aware that something catastrophic was happening inside him. A severe headache that had persisted for days had taken a sudden turn for the worse, and a clear inner voice ordered him to obtain immediate help. With determined effort, he tapped out the digits ¿9-1-1¿ on his phone¿bringing an ambulance to his door quickly and saving his life. Emergency Room doctors would soon learn that Professor Gustafson, a renowned American mathematician, had suffered a deep brain hemorrhage, and that the situation was dire. By the time his condition was diagnosed, blood had pooled into all four ventricles of Gustafson¿s brain and he was comatose.Against all odds and surprising everyone, the author emerged from a near-death state to go on to what he calls his ¿Second Life¿. This is the story of his miraculous journey of recovery, an inspirational tale of grit and determination, in his own words.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 84 pp. Englisch.

Taschenbuch. Condizione: Neu. Neuware -Although it is popularly assumed that the history of computing before the second half of the 20th century was unimportant, in fact the Industrial Revolution was made possible and even sustained by a parallel revolution in computing technology. An examination and historiographical assessment of key developments helps to show how the era of modern electronic computing proceeded from a continual computing revolution that had arisen during the mechanical and the electrical ages.This unique volume introduces the history of computing during the ¿first¿ (steam) and ¿second¿ (electricity) segments of the Industrial Revolution, revealing how this history was pivotal to the emergence of electronic computing and what many historians see as signifying a shift to a post-industrial society. It delves into critical developments before the electronic era, focusing on those of the mechanical era (from the emergence of the steam engine to that of the electric power network) and the electrical era (from the emergence of the electric power network to that of electronic computing). In so doing, it provides due attention to the demarcations between¿and associated classifications of¿artifacts for calculation during these respective eras. In turn, it emphasizes the history of comparisons between these artifacts.Topics and Features:motivates exposition through a firm historiographical argument of important developmentsexplores the history of the slide rule and its use in the context of electrificationexamines the roles of analyzers, graphs, and a whole range of computing artifacts hitherto placed under the allegedly inferior class of analog computersshows how the analog and the digital are really inseparable, with perceptions thereof depending on either a full or a restricted view of the computing processinvestigates socially situated comparisons of computing history, including the effects of a politicaleconomy of computing (one that takes into account cost and ownership of computing artifacts)assesses concealment of analog-machine labor through encasement (¿black-boxing¿)Historians of computing, as well as those of technology and science (especially, energy), will find this well-argued and presented history of calculation and computation in the mechanical and electrical eras an indispensable resource. The work is a natural textbook companion for history of computing courses, and will also appeal to the broader readership of curious computer scientists and engineers, as well as those who generally just have a yearn to learn the contextual background to the current digital age.'In this fascinating, original work, Tympas indispensably intertwines the histories of analog and digital computing, showing them to be inseparable from the evolution of social and economic conditions.

Taschenbuch. Condizione: Neu. Neuware -Since the invention of the telescope 400 years ago, astronomers have rapidly discovered countless celestial objects. But how does one make sense of it all Astronomer and former NASA Chief Historian Steven J. Dick brings order to this menagerie by defining 82 classes of astronomical objects, which he places in a beginner-friendly system known as 'Astronomy¿s Three Kingdoms.¿ Rather than concentrating on technicalities, this system focuses on the history of each object, the nature of its discovery, and our current knowledge about it.The ensuing book can therefore be read on at least two levels. On one level, it is an illustrated guide to various types of astronomical wonders. On another level, it is considerably more: the first comprehensive classification system to cover all celestial objects in a consistent manner.Accompanying each spread are spectacular historical and modern images. The result is a pedagogical tour-de-force, whereby readers can easily master astronomy¿s three realms of planets, stars, and galaxies.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 508 pp. Englisch.

Buch. Condizione: Neu. Neuware -This book offers a selection from among István Hargittai¿s non-technical articles that focus on the culture of discoveries and scientists, rather than on actual research. István Hargittai is an internationally renowned physical chemist with interests extending to the arts, human traits, the nature of discoveries, and the relationship between science and society. Over the course of his research career, he has interacted with hundreds of the best minds of our time and published a wealth of articles that are rich in science yet easy to understand, regardless of the reader¿s background.This book presents a collection of these contributions, which explore the relationship between the arts and science, analyze the motivations of scientific discoveries and the personalities of discoverers, comment on the relationship between science and society, and examine the application of the symmetry concept and its ubiquitous presence. This unique book is intended not only for professionalresearchers, but for all individuals interested in the cultural aspects of science.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 508 pp. Englisch.

Buch. Condizione: Neu. Neuware -This book, which will appeal to all with an interest in the history of radiology and physics, casts new light on the life and career of Wilhelm Conrad Röntgen, showing how his personality was shaped by his youth in the Netherlands and his teachers in Switzerland. Beyond this, it explores the technical developments relevant to the birth of radiology in the late nineteenth century and examines the impact of the discovery of X-rays on a broad range of scientific research.Röntgen (1845-1923) was born in Lennep, Germany, but emigrated with his family to the Netherlands in 1848. As a 17-year-old he moved to Utrecht, entering the Technical School and living at the home of Dr. Jan Willem Gunning. In this well-educated family he was stimulated to continue his studies at university. In 1868 he received a diploma from the Federal Polytechnic School in Zurich and just a year later completed a PhD in physics. He followed his mentor, August Kundt, to the universities of Würzburg (1870) and Strasburg (1872) and married Anna Ludwig in 1872. In 1879 Röntgen gained his first professorship at a German University, in Giessen, followed by a chair in Würzburg in 1888. Here he discovered X-rays in 1895, for which he received the first Nobel Prize in physics in 1901. From 1900 until his retirement in 1921 he occupied the chair of physics at the Munich University.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 224 pp. Englisch.

Buch. Condizione: Neu. Neuware -The presumed sovereignty of individuals and the facilitating powers of the markets have generated a universal and ethically neutral conception of both social and economic organisation. This ground-breaking text re-examines the purpose of society and the role of economics in it, arguing that the absence of a beneficial natural order calls for the role of the collective in social and economic life to be revisited. Drawing on some key figures marking milestones in the evolution of social and economic thinking, the author offers a critique of mainstream economics as a way of thinking and as a provider of guiding principles for economic and social organisation.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 448 pp. Englisch.
