Quantum physics is often perceived as a weird and abstract theory, which physicists must use in order to make correct predictions. But many recent experiments have shown that the weirdness of the theory simply mirrors the weirdness of phenomena: it is Nature itself, and not only our description of it, that behaves in an astonishing way. This book selects those, among these typical quantum phenomena, whose rigorous description requires neither the formalism, nor an important background in physics. The first part of the book deals with the phenomenon of single-particle interference, covering the historical questions of wave-particle duality, objective randomness and the boundary between the quantum and the classical world, but also the recent idea of quantum cryptography. The second part introduces the modern theme of entanglement, by presenting two-particle interference phenomena and discussing Bell's inequalities. A concise review of the main interpretations of quantum physics is provided.

In The Entangled God, Kirk Wegter-McNelly addresses the age-old theological question of how God is present to the world by constructing a novel, scientifically informed account of the God–world relation. Drawing on recent scientific and philosophical work in "quantum entanglement," Wegter-McNelly develops the metaphor of "divine entanglement" to ground the relationality and freedom of physical process in the power of God’s relational being. The Entangled God makes a three-fold contribution to contemporary theological and religious discourse. First, it calls attention to the convergence of recent theology around the idea of "relationality." Second, it introduces theological and religious readers to the fascinating story of quantum entanglement. Third, it offers a robust "plerotic" alternative to kenotic accounts of God’s suffering presence in the world. Above all, this book takes us beyond the view of theology and science as adversaries and demonstrates the value of constructively relating these two important areas of intellectual investigation.

Quantum physics has, on the one hand, drastically changed our theoretical description of the physical world and has, on the other hand, revolutionized everyday life, by allowing us to build lasers, atomic clocks used in GPS, and semiconductor-based devices such as laptop computers and smartphones. The object of this book is to give a self-contained introduction to both aspects. It contains a detailed account of the foundational principles: superposition, entanglement, quantum non-locality, decoherence and measurement theory, and of some selected applications: quantum cryptography and quantum computers, cold atoms, light emitting and laser diodes, and atomic clocks. The book is aimed at a general audience and the only prerequisite is a high-school background in mathematics.

Many books explain what is known about the universe. This book investigates what cannot be known. Rather than exploring the amazing facts that science, mathematics, and reason have revealed to us, this work studies what science, mathematics, and reason tell us cannot be revealed. In The Outer Limits of Reason, Noson Yanofsky considers what cannot be predicted, described, or known, and what will never be understood. He discusses the limitations of computers, physics, logic, and our own thought processes.Yanofsky describes simple tasks that would take computers trillions of centuries to complete and other problems that computers can never solve; perfectly formed English sentences that make no sense; different levels of infinity; the bizarre world of the quantum; the relevance of relativity theory; the causes of chaos theory; math problems that cannot be solved by normal means; and statements that are true but cannot be proven. He explains the limitations of our intuitions about the world -- our ideas about space, time, and motion, and the complex relationship between the knower and the known.Moving from the concrete to the abstract, from problems of everyday language to straightforward philosophical questions to the formalities of physics and mathematics, Yanofsky demonstrates a myriad of unsolvable problems and paradoxes. Exploring the various limitations of our knowledge, he shows that many of these limitations have a similar pattern and that by investigating these patterns, we can better understand the structure and limitations of reason itself. Yanofsky even attempts to look beyond the borders of reason to see what, if anything, is out there.

In trying to understand the atom, physicists built quantum mechanics, the most successful theory in science and the basis of one-third of our economy. They found, to their embarrassment, that with their theory, physics encounters consciousness. Authors Bruce Rosenblum and Fred Kuttner explain all this in non-technical terms with help from some fanciful stories and anecdotes about the theory's developers. They present the quantum mystery honestly, emphasizing what is and what is not speculation. Quantum Enigma's description of the experimental quantum facts, and the quantum theory explaining them, is undisputed. Interpreting what it all means, however, is heatedly controversial. But every interpretation of quantum physics involves consciousness. Rosenblum and Kuttner therefore turn to exploring consciousness itself--and encounter quantum mechanics. Free will and anthropic principles become crucial issues, and the connection of consciousness with the cosmos suggested by some leading quantum cosmologists is mind-blowing. Readers are brought to a boundary where the particular expertise of physicists is no longer the only sure guide. They will find, instead, the facts and hints provided by quantum mechanics and the ability to speculate for themselves. In the few decades since the Bell's theorem experiments established the existence of entanglement (Einstein's "spooky action"), interest in the foundations, and the mysteries, of quantum mechanics has accelerated. In recent years, physicists, philosophers, computer engineers, and even biologists have expanded our realization of the significance of quantum phenomena. This second edition includes such advances. The authors have also drawn on many responses from readers and instructors to improve the clarity of the book's explanations.

Jean Watson's Theory of Human Caring (Caritas) is now used in approximately 300 health care institutions in the United States and other institutions worldwide. This is the first international compendium of Caritas research, presenting the findings of 41 studies from 7 countries. The book examines similarities and differences in the ways in which each country applies Watson's Theory and documents the outcomes of these interventions. It addresses relationships between nurses and patients, nurses and their colleagues, self-care, and how Caritas is used to resolve outcome issues system-wide. The book discusses at length eight different Caring Factor surveys, primary research tools for those using the Caritas process, which identify constructs that either support or impede caring in multiple settings. The first section focuses on the theoretical underpinnings of Caritas and presents seven adaptations of the Caring Factor Survey. Section II addresses measurements and methods for facilitating a caring relationship between nurse and patient. Measurements and interventions to facilitate Caritas in a variety of settings is the focus of Section III, and the final sections address the international measurement and international comparisons of Caritas. The volume will be an important resource for nurse leaders, educators, administrators in academia including unit managers, and for hospitals with or seeking Magnet status. The book serves as a complement to Watson's Assessing and Measuring Caring in Nursing and Health Care and Creating a Caring Science Curriculum: An Emancipatory Pedagogy for Nursing. A co-publication with the Watson Caring Institute, this volume: Presents cutting-edge tools derived from the Caring Factor Survey for measuring caring in multiple contexts Discusses similarities and differences in caring contexts across nations Documents outcomes of Caritas in varied settings in the United States and internationally Addresses nurse-patient and nurse-colleague relationships, self-care, and resolution of system-wide outcome issues

Physics is a complex, even daunting topic, but it is also deeply satisfying—even thrilling. And liberated from its mathematical underpinnings, physics suddenly becomes accessible to anyone with the curiosity and imagination to explore its beauty. Science without math? It’s not that unusual. For example, we can understand the concept of gravity without solving a single equation. So for all those who may have pondered what makes blueberries blue and strawberries red; for those who have wondered if sound really travels in waves; and why light behaves so differently from any other phenomenon in the universe, it’s all a matter of quantum physics. Absolutely Small presents (and demystifies) the world of quantum science like no book before. It explores scientific concepts—from particles of light, to probability, to states of matter, to what makes greenhouse gases bad—in considerable depth, but using examples from the everyday world. Challenging without being intimidating, accessible but not condescending, Absolutely Small develops the reader’s intuition for the very nature of things at their most basic and intriguing levels.

Hurry, hurry, hurry! Step right up! Welcome to Quantumland! Fall into an atom and dodge electrons! See the amazing Emperor think his clothes into existence! Dance with the Three Quark Brothers at the Particle MASSquerade! An you need is a sense of adventure-no mathematics required! Alice in Quantumland is Robert Gilmore's amazing fantasy ride through the landscape of quantum physics-the interrelated group of theories on the nature of subatomic particles that modern scientists use to, explain the physical universe. Through the allegory of Alice's adventures and encounters, Gilmore makes the essential features of the quantum world clear and accessible. It is a thrilling introduction to some essential, often difficult-to-grasp concepts about the world we inhabit. You've heard about Alice's adventures through the looking glass. Well, Alice is about to embark on another amazing journey. She's going to shrink again-to the size of a nuclear particle-but she's not going down the rabbit hole. She's headed for Quantumland. And what is Quantumland? Think of it as an intellectual amusement park smaller than an atom, where every ride, game, and attraction demonstrates a different aspect of quantum mechanics-the often baffling, always intriguing theoretical framework that seems to provide the most accurate explanations of the way things arc in the physical world. In this masterful blend of fantasy and science, Robert Gilmore uses the allegory of Alice's travels to make the uncertainty principle, Pauli's principle, high-energy particle physics, and other crucial parts of quantum theory accessible and exciting. Once in Quantumland, Alice experiences various quantum effects (at one point going backward in time and running into herself). She also meets a number of strange characters who help her (and you) understand the nature of the quantum world. There is: * the Uncertain Accountant, whose attempts to balance the books at the Heisenberg Energy Bank arc being flummoxed by energy fluctuations; * the State Agent, Who shows Alice how atoms can bc two places at once; * the Three Quark Brothers, who take Alice around the floor in one of the Castle Rutherford's famous Collider Dances; * the Emperor, whose conscious mind makes his new clothes real; and more. Cleverly conceived and written, and delightfully illustrated, Alice in Quantumland brings some crucial yet often elusive scientific concepts within reach of the everyday reader. You don't need to know much about mathematics to follow our heroine's escapades. There is only one equation in the entire book! All you need is a taste for intellectual adventure and healthy curiosity about the world around us.
