Get the inside story of American Artificial Intelligence (AI) failure and fall: Learn how to reassume American AI leadership and win against China On the eve of the Sino-American great power competition General Mattis challenged America to move forward at the speed of relevance. To compete effectively America needed to excel in its AI capacity. The call fell on deaf ears - and years later the nation found itself sliding towards a state of irrelevance on the global stage. A series of blunders contributed to what President Biden calls American AI's "failing and falling behind." This is the story of American AI's fall from grace. Capturing the live moments of American excitement and mastery of AI to the tragedy of ending up behind China, the authors give a behind the scenes account of what transpired. Get an inside view on who dropped the ball at a time when America needed its best leadership. As the mystery unravels, it shows the great misses and deceptions, colossal mistakes, policy failures, and negligence that cost America its leadership position. This story could become the story of America’s own decline and fall. But there is hope. In the past America has shown resilience to bounce back from the agony of defeat to win in the long run. This book gives a path to rebuild American AI and secure such a victory. Whether you are a business leader or a policy analyst, a supply chain expert or an academic, a congressmember or an agency head At the Speed of Irrelevance: How America Blew Its AI Leadership Position and How to Regain It will change your thinking about your responsibility to your firms, agencies, and the country. This will be the most timely and patriotic book you will ever read.

The book provides a summary of the historical evolution of dimensional analysis, and frames the problem of dimensions, systems of units and similarity in a vision dominated by the conventions that formalise even the exact sciences. The first four chapters address the definitions, with few dimensional analysis theorems and similarity criteria. There is also the analysis of self-similarity, both of first and second kind, with a couple of completely solved problems, framed within the group theory. From chapter 5 onward, the focus is on applications in some of the engineering sectors. The number of topics is necessarily limited, but, almost always, there are details, calculations and treatment of assumptions. The book contains descriptions of some of the experimental apparatuses currently used for the realisation of physical models, such as the wind tunnel, the shaking table, the centrifuge, and with the exclusion of many others, which can be found in specialist monographies. Measurement techniques and instrumentation and statistical data processing is also available in other books. Some more specific notions, required by the context, are reported in the appendix, where appears also the description of numerous dimensionless groups, all of engineering interest, but with the exclusion of many others related to physical processes of electrical nature or physics of particles. A glossary lists the meaning of some specific terms typical of dimensional analysis and used in the book.

‘Heat breaks up charcoal and puts sulphur dioxide in’; ‘The air pulls faster on heavy masses.’ These and other similar statements by school-aged children untutored in physics carry two messages. First, children’s pre-instructional conceptions of the physical world are a far cry from the received wisdom of science; second, despite their lack of orthodoxy, children’s conceptions carry a definite sense of causal mechanism. This sense of mechanism is the focal concern of this book, originally published in 1998, for it raises issues of central importance to both psychological theory and educational practice. In particular, some psychologists have claimed that human cognition is organised around causal mechanisms along the lines of a theory. This carries specific implications for teaching. Does the existence in children’s thinking of causal mechanisms relating to the physical world support these psychologists? Does this have consequences for the teaching of science? Christine Howe reviews evidence relating to pre-instructional conceptions in three broad topic areas: heat and temperature; force and motion; floating and sinking. A wide range of published work is discussed, including the author’s own research. In addition, a new study covering all three topic areas is reported for the first time. The message is that causal mechanisms can indeed play an organising role, that untutored cognition can in other words be genuinely theoretical. However, this tendency is highly domain-specific, occurring in some topic areas but not in others. Having drawn these conclusions, Christine Howe discusses their meaning in terms of both cognitive development and educational practice. A model is outlined which synthesises Piagetian action-groundedness with Vygotskyan cultural-symbolism and has a distinctive message for classrooms. This title will be useful to cognitive and developmental psychologists and to science educators alike.

Relevance drives our actions and channels our attention; it shapes how we make sense of the world and communicate with each other. Irrelevance spreads a twilight which blurs the line between information we do not want to access and information we cannot access. In disciplines as diverse as philosophy, sociology, the information sciences and linguistics, “relevance” has been proposed as a key concept. This book is the first to bring together the often unrelated traditions. Researchers from different fields discuss relevance and relate it to the challenges of “irrelevance”, which have so far been neglected despite their significance for our chances of making well-informed decisions and understanding others. The contributions focus on theoretical and conceptual questions, on specific factors and fields, and on practical and political implications of relevance and irrelevance as forces which are even stronger when they remain in the background.

This book offers a readable introduction to the main aspects of thought experimenting in philosophy and science (together with related imaginative activities in mathematics and linguistics). It presents the main options in understanding thought experiments, from empiricism to Platonism, and discusses their strengths and weaknesses. However, it also provides some original perspectives on the topic. Firstly, it provides a new definition and analysis of thought experimenting that brings it closer to laboratory experimenting. Secondly, it develops the author’s earlier theory of “mental modelling”, proposed some decades ago by him, and some other researchers in the field as the crucial procedure in thought experimenting. The mental modelling approach links work with thought experimenting to cognitive science and to research on mental simulation which is a hot topic in present-day research. Thirdly, it proposes a principled way to respond to criticism of thought experimenting by “experimental philosophers” as they have been dominating the present-day debates. The response suggests a possible ameliorative, self-help project for thought experimenting. Finally, the book provides a way to systematize the history of important thought experiments in science and philosophy and thus connects, in an original way, the systematic investigation of experimenting to the historical work of famous thought experiments. It is of interest to scholars interested in history of ideas and philosophy of science.

An influential pastor, podcaster, and thought leader believes it's not only possible to predict life's hardest moments, but also to alter outcomes, overcome challenges, and defeat your fiercest adversaries. Founding Pastor of one of North America's most influential churches, Carey Nieuwhof wants to help you avoid and overcome life's seven hardest and most crippling challenges: cynicism, compromise, disconnectedness, irrelevance, pride, burnout, and emptiness. These are challenges that few of us expect but that we all experience at some point. If you have yet to confront these obstacles, Carey provides clear tools and guidelines for anticipation and avoidance. On the other hand, if you already feel stuck in a painful experience or are wrestling with one of these challenges, he provides the steps you need to find a way out and a way forward into a more powerful and vibrant future.
