Cogito, ergo sum. ("I think, therefore I am.") When Descartes quipped this, he erroneously split thinking from feeling. He assumed thoughts emerge from a substance other than feeling. This is a historic tragedy, and it is unnecessary. It brings us to a risky end-game. When we attempt to meld preconceived thought with evoked feelings, we come to the craft of "spin doctors." Instead, there is a natural path for connecting thinking and feeling. It involves emotional reflection at the time that understandings are created. This book draws attention to a form of dialogue which is called design dialogue. Design dialogue constructs new meaning from the bottom up. Individuals construct new meanings through individual thinking. In design dialogue, meaning results from group thinking. Group thinking is not as simple as thinking individually while being present within a group. The design process results in a series of co-constructed learning artifacts which, ultimately, constitute a new understanding. The process is concurrently emotional and cognitive, and melding emotion and cognition is achievable with effective design dialogue methods. The first chapter introduces emotion as the catalyst for considering questions, persisting in reflection, and concluding a cycle of thought. This chapter fills in gaps with the treatment of emotion and cognition. The second chapter lays out the sequence of observation-taking, sensemaking, meaning-making, and perspective-taking that are essential steps in thinking. Frameworks for thinking in educational traditions focus not so much on the neurological mechanics of the thought process but rather on the overall internalization of a "way" of understanding things. A third chapter presents a methodology for managing a design dialogue. Group facilitators generally invent and modify their own approaches for leading design projects. This chapter presents a codified approach that offers an advantage of supporting continuous improvement of complex design management methodology. And the final chapter considers the emergence of a sapient group-mind through the agency of design dialogue. This conjectured group-mind is considered in the context of the civic infrastructure that is needed to sustain the continual growth of the human superorganism structure. As humanity has moved from tribes, to cities, to institutions, and now to globally connected networks, each leap forward has been accompanied by profound changes in social practices and belief systems. Recent findings from the field of cognitive science have confirmed a suspicion that we have long held about each other. Individual thinking is biased and flawed. Inclusive and democratically managed discussion, deliberation and design all help to identify and dampen flawed understandings. The individual mind, an essential ingredient in the human spirit, is now, as a matter of practical necessity, bending to the wisdom of a well-informed group mind. The speed and strength of newly emerging social forces and evolving civic trends point to the conclusion that we are on the threshold for a new way of being. This book seeks to evoke reflection on how we can start communicating in a way that prepares us for life in that new future.

Heavy electrons are found among a number of lanthanide and actinide compounds, and are characterized by a large effective mass which becomes comparable to the mass of a muon. Heavy electrons exhibit rich phenomena such as unconventional superconductivity, weak anti- ferromagnetism, or pseudo meta-magnetism. This book is intended not only as a monograph, but can readily serve as an advanced textbook on theoretical and experimental physics of strongly correlated electrons. Over the last two decades, heavy electrons have been the focus of very active experimental and theoretical studies. Many established ideas and techniques have been insufficient to describe and understand heavy electrons and their impact properly. On the theoretical side, quantum fluctuations make mean-field theories difficult to handle, while on the experimental side, extreme conditions such as strong magnetic fields and pressure at ultra-low temperatures may be required. Heavy electron systems as described in this book offer a case study for applying and testing most of the major tools in theoretical and experimental condensed matter physics. Graduate students and researchers working on strongly correlated condensed matter systems will find in this book a comprehensive introduction and many examples how conventional concepts of solids may work or not work, and how they can be refined and sharpened in the context of heavy electron systems.
People who work in an office spend at least a third of their lifetime in these spaces. The planning of office and administration buildings can therefore contribute a great deal to the satisfaction and well-being of future users. The book looks at the health-relevant factors that affect people in office and administration buildings and therefore deserve special attention in the planning process. In doing so, the authors are guided by a concept of health as defined by the World Health Organization: Accordingly, health encompasses mental as well as social and physical well-being and thus goes far beyond the factors laid down in legal norms and guidelines. In this volume, architects and designers, physicians and ergonomists deal with all aspects of interior design seen from a health perspective: What role does colour design play, what significance do light, air and noise have? What does a demand-oriented building technology look like and how is the office furniture adequately designed? Which medical and hygienic aspects have to be considered? How can offices be designed in terms of work-life balance and how will the office change in the course of digitalisation? The book serves as a guideline that can be applied chapter by chapter in the planning of health-promoting office spaces - depending on the interests of the reader. Problems that arise are discussed using examples, and checklists help you with planning and implementation. The guide is aimed at building owners, architects, engineers, but also at lawyers, psychologists and doctors as well as university members in the field of economics and engineering.
The authors of this book present a thorough discussion of the optical properties of solids, with a focus on electron states and their response to electrodynamic fields. A review of the fundamental aspects of the propagation of electromagnetic fields, and their interaction with condensed matter, is given. This is followed by a discussion of the optical properties of metals, semiconductors, and collective states of solids such as superconductors. Theoretical concepts, measurement techniques and experimental results are covered in three interrelated sections. Well-established, mature fields are discussed (for example, classical metals and semiconductors) together with modern topics at the focus of current interest. The substantial reference list included will also prove to be a valuable resource for those interested in the electronic properties of solids. The book is intended for use by advanced undergraduate and graduate students, and researchers active in the fields of condensed matter physics, materials science and optical engineering.
Superconductivity: Physics and Applications brings together major developments that have occurred within the field over the past twenty years. Taking a truly modern approach to the subject the authors provide an interesting and accessible introduction. Brings a fresh approach to the physics of superconductivity based both on the well established and convergent picture for most low-Tc superconductors, provided by the BCS theory at the microscopic level, and London and Ginzburg-Landau theories at the phenomenological level, as well as on experiences gathered in high-Tc research in recent years. Includes end of chapter problems and numerous relevant examples Features brief interviews with key researchers in the field A prominent feature of the book is the use of SI units throughout, in contrast to many of the current textbooks on the subject which tend to use cgs units and are considered to be outdated
Photonic Instrumentation: Sensing and Measuring with Lasers is designed as a source for university-level courses covering the essentials of laser-based instrumentation, and as a useful reference for working engineers. Photonic instruments have very desirable features like non-contact operation and unparalleled sensitivity. They have quickly become a big industrial success, passing unaffected through the bubble years and, not any less important, well-established methods in measurement science. This book offers coverage of the most proven instruments, with a balanced treatment of the optical and electronic aspects involved. It also attempts to present the basic principles, develop the guidelines of design and evaluate the ultimate limits of performances set by noise. The instruments surveyed include: alignment instruments, such as wire diameter and particle size analyzers, telemeters, laser interferometers and self-mixing interferometers, and speckle pattern instruments, laser doppler velocimeters, gyroscopes, optical fiber sensors and quantum sensing. A few appendices offer convenient reference material for key principles on lasers, optical interferometers, propagation, scattering and diffraction.
Gets you quickly up to speed with the theoretical and practical aspects of free space optical systems engineering design and analysis One of today's fastest growing system design and analysis disciplines is free space optical systems engineering for communications and remote sensing applications. It is concerned with creating a light signal with certain characteristics, how this signal is affected and changed by the medium it traverses, how these effects can be mitigated both pre- and post-detection, and if after detection, it can be differentiated from noise under a certain standard, e.g., receiver operating characteristic. Free space optical systems engineering is a complex process to design against and analyze. While there are several good introductory texts devoted to key aspects of optics—such as lens design, lasers, detectors, fiber and free space, optical communications, and remote sensing—until now, there were none offering comprehensive coverage of the basics needed for optical systems engineering. If you're an upper-division undergraduate, or first-year graduate student, looking to acquire a practical understanding of electro-optical engineering basics, this book is intended for you. Topics and tools are covered that will prepare you for graduate research and engineering in either an academic or commercial environment. If you are an engineer or scientist considering making the move into the opportunity rich field of optics, this all-in-one guide brings you up to speed with everything you need to know to hit the ground running, leveraging your experience and expertise acquired previously in alternate fields.
