The book explores the variety of meanings of contextuality across different disciplines, with the emphasis on quantum physics and on psychology.
Introducing graduate students and researchers to mathematical physics, this book discusses two recent developments: the demonstration that causality can be defined on discrete space-times; and Sewell's measurement theory, in which the wave packet is reduced without recourse to the observer's conscious ego, nonlinearities or interaction with the rest of the universe. The definition of causality on a discrete space-time assumes that space-time is made up of geometrical points. Using Sewell's measurement theory, the author concludes that the notion of geometrical points is as meaningful in quantum mechanics as it is in classical mechanics, and that it is impossible to tell whether the differential calculus is a discovery or an invention. Providing a mathematical discourse on the relation between theoretical and experimental physics, the book gives detailed accounts of the mathematically difficult measurement theories of von Neumann and Sewell.
It is naturally important for any of us to have a correct view of the universe we are in. Having realized that the Newtonian world-view is untenable, this book joins others that are searching for an alternative world-view. It is unique in using quantum physics to promote this search.One aim of the book is to present a lucid exposition of quantum mechanics in terms accessible to the general reader. Another aim is to show that realism (the belief that the outside world exists “from its own side” regardless of acts of consciousness) and locality (the belief that nothing moves faster than light) are invalid, and should be replaced by a new paradigm according to which the universe is alive. A third aim is to show that the thinking of quantum physicists evokes the philosophies of Plato and Plotinus.The revised edition will include a conversation between two fictional characters to elucidate the discussion of the meaning of wave functions.
The untold story of Albert Einstein's role as the father of quantum theory Einstein and the Quantum reveals for the first time the full significance of Albert Einstein's contributions to quantum theory. Einstein famously rejected quantum mechanics, observing that God does not play dice. But, in fact, he thought more about the nature of atoms, molecules, and the emission and absorption of light—the core of what we now know as quantum theory—than he did about relativity. A compelling blend of physics, biography, and the history of science, Einstein and the Quantum shares the untold story of how Einstein—not Max Planck or Niels Bohr—was the driving force behind early quantum theory. It paints a vivid portrait of the iconic physicist as he grappled with the apparently contradictory nature of the atomic world, in which its invisible constituents defy the categories of classical physics, behaving simultaneously as both particle and wave. And it demonstrates how Einstein's later work on the emission and absorption of light, and on atomic gases, led directly to Erwin Schrödinger's breakthrough to the modern form of quantum mechanics. The book sheds light on why Einstein ultimately renounced his own brilliant work on quantum theory, due to his deep belief in science as something objective and eternal.

“One of the best popular accounts of how Einstein and his followers have been trying to explain the universe for decades” (Kirkus Reviews, starred review). Physicists have been exploring, debating, and questioning the general theory of relativity ever since Albert Einstein first presented it in 1915. This has driven their work to unveil the universe’s surprising secrets even further, and many believe more wonders remain hidden within the theory’s tangle of equations, waiting to be exposed. In this sweeping narrative of science and culture, an astrophysicist brings general relativity to life through the story of the brilliant physicists, mathematicians, and astronomers who have taken up its challenge. For these scientists, the theory has been both a treasure trove and an enigma. Einstein’s theory, which explains the relationships among gravity, space, and time, is possibly the most perfect intellectual achievement of modern physics—yet studying it has always been a controversial endeavor. Relativists were the target of persecution in Hitler’s Germany, hounded in Stalin’s Russia, and disdained in 1950s America. Even today, PhD students are warned that specializing in general relativity will make them unemployable. Still, general relativity has flourished, delivering key insights into our understanding of the origin of time and the evolution of all the stars and galaxies in the cosmos. Its adherents have revealed what lies at the farthest reaches of the universe, shed light on the smallest scales of existence, and explained how the fabric of reality emerges. Dark matter, dark energy, black holes, and string theory are all progeny of Einstein’s theory. In the midst of a momentous transformation in modern physics, as scientists look farther and more clearly into space than ever before, The Perfect Theory exposes the greater relevance of general relativity, showing us where it started, where it has led—and where it can still take us.
The world of management is in crisis - the old remedies no longer work and organizations are failing at an increasing rate. Although many talk of 'joined up thinking', few offer practical guidance on how to achieve this in organizations. The Fractal Organization sets down the practical implications of a well tested systemic approach to building organizations that are capable of surviving and flourishing in these turbulent times. "An excellent read…Many organizations fail at the mercy of their own ignorance. The author has done an excellent job in making ‘the science of effective organization’ accessible to management, providing them with a new knowledge to deal with the uncertainties that the markets place upon them." Stephen J. Brewis, Business Architect, British Telecom "...one of the most interesting, thorough and rigorous guides to management that I have ever read, … introduces new insights in every chapter… carries a credibility which acts as a counterbalance to the sometimes difficult message which he conveys which is that a lot of mainstream management practice is at best ineffective and at worst downright destructive. I would recommend this book to anyone interested in management or systems thinking." Penny Marrington, Course Chair, Systems Group, Open University "In my opinion this book manages to present sound academic theory that is relevant and helpful to the practitioner in the business. I experienced several A-HA moments." Pauline Marsh, Strategy Director, CS&S International, BAE SYSTEMS "The insights of the Viable System Model have been open only to a select few for much too long. Hoverstadt has gone furthest in bringing these ideas to a wider audience…Management books have too often been serious but not practical, or practical but not serious. This book is both brilliantly serious and practical, and often entertaining too." Professor Peter Kawalak, Manchester Business School "Integrates mainstream management ideas with the systems ideas underpinning the VSM, and flows and reads well. As a starting point for developing understanding of the VSM in today's world this book improves greatly on all books that have gone before, I would certainly recommend it to colleagues, clients, and students." Dr. Robin Asby, Course Chair, Communication and Systems, Open University
Modern societies and organizations are characterized by multiple kinds of observations, systems, or rationalities, rather than singular identities and clear hierarchies. This holds true for healthcare where we find a range of different perspectives – from medicine to education, from science to law, from religion to politics – brought together in different types of arrangements. This innovative volume explores how this polycontexturality plays out in the healthcare arena. Drawing on systems theory, and Luhmann’s theory of social systems as communicative systems in particular, the contributors investigate how things – drugs, for example – and bodies are observed and constructed in different ways under polycontextural conditions. They explore how the different types of communication and observation are brought into workable arrangements – without becoming identical or reconciled – and discuss how health care organizations observe their own polycontexturality. Providing an analysis of healthcare structures that is up to speed with the complexity of healthcare today, this book shows how society and its organizations simultaneously manage contexts that do not fit together. It is an important work for those with an interest in health and illness, social theory, Niklas Luhmann, organizations and systems theory from a range of backgrounds including sociology, health studies, political science and management.
More than fifty years after his death, Albert Einstein's vital engagement with the world continues to inspire others, spurring conversations, projects, and research, in the sciences as well as the humanities. Einstein for the 21st Century shows us why he remains a figure of fascination. In this wide-ranging collection, eminent artists, historians, scientists, and social scientists describe Einstein's influence on their work, and consider his relevance for the future. Scientists discuss how Einstein's vision continues to motivate them, whether in their quest for a fundamental description of nature or in their investigations in chaos theory; art scholars and artists explore his ties to modern aesthetics; a music historian probes Einstein's musical tastes and relates them to his outlook in science; historians explore the interconnections between Einstein's politics, physics, and philosophy; and other contributors examine his impact on the innovations of our time. Uniquely cross-disciplinary, Einstein for the 21st Century serves as a testament to his legacy and speaks to everyone with an interest in his work.
