This book surveys some of the important research work carried out by Indian scientists in the field of pure and applied probability, quantum probability, quantum scattering theory, group representation theory and general relativity. It reviews the axiomatic foundations of probability theory by A.N. Kolmogorov and how the Indian school of probabilists and statisticians used this theory effectively to study a host of applied probability and statistics problems like parameter estimation, convergence of a sequence of probability distributions, and martingale characterization of diffusions. It will be an important resource to students and researchers of Physics and Engineering, especially those working with Advanced Probability and Statistics.

Contemporary politics is mass-communication politics. Politicians are not only seen and heard, they are seen and heard in close-up through television appearances, speeches, interviews, and on social media. In this book, the authors analyse the ways in which politicians communicate with each other, the media, and the electorate; they also discuss the implications of contemporary political discourse on the democratic process as a whole. Politicians in interviews are typically castigated for their evasiveness. However, microanalytic research shows that there is more to political discourse than this apparent ambiguity. This book reveals how equivocation, interruptions, and personal antagonism can offer valuable insights into a politician's communicative style. The authors review their empirical research not only on political interviews, but also on speeches, parliamentary debates, and political journalism. Further insights include how political speakers interact with their audiences, how party leaders engage in adversarial discourse at PMQs, and how the spoken messages of politicians can be affected by modern journalistic editing techniques. Thereby, this research generates greater awareness of communicative practices in a diverse range of political contexts. While the interviews and parliamentary debates analysed pertain to UK politics, the speeches also draw on the USA, and European and Far Eastern nations. This engaging book is a fascinating resource for students and academics in psychology, politics, communication, and other related disciplines such as sociology and linguistics. The research is also extremely relevant to policy makers and practitioners in politics and political journalism.

INSTANT NEW YORK TIMES BESTSELLER "A new masterpiece from one of my favorite authors... [How The World Really Works] is a compelling and highly readable book that leaves readers with the fundamental grounding needed to help solve the world's toughest challenges."-Bill Gates "Provocative but perceptive . . . You can agree or disagree with Smil-accept or doubt his 'just the facts' posture-but you probably shouldn't ignore him."-The Washington Post An essential analysis of the modern science and technology that makes our twenty-first century lives possible-a scientist's investigation into what science really does, and does not, accomplish. We have never had so much information at our fingertips and yet most of us don't know how the world really works. This book explains seven of the most fundamental realities governing our survival and prosperity. From energy and food production, through our material world and its globalization, to risks, our environment and its future, How the World Really Works offers a much-needed reality check-because before we can tackle problems effectively, we must understand the facts. In this ambitious and thought-provoking book we see, for example, that globalization isn't inevitable-the foolishness of allowing 70 per cent of the world's rubber gloves to be made in just one factory became glaringly obvious in 2020-and that our societies have been steadily increasing their dependence on fossil fuels, such that any promises of decarbonization by 2050 are a fairy tale. For example, each greenhouse-grown supermarket-bought tomato has the equivalent of five tablespoons of diesel embedded in its production, and we have no way of producing steel, cement or plastics at required scales without huge carbon emissions. Ultimately, Smil answers the most profound question of our age: are we irrevocably doomed or is a brighter utopia ahead? Compelling, data-rich and revisionist, this wonderfully broad, interdisciplinary guide finds faults with both extremes. Looking at the world through this quantitative lens reveals hidden truths that change the way we see our past, present and uncertain future.

Insecurity is an inevitable part of being human. Although life is insecure for every organism, humans alone are burdened by knowing that this is so. This ground-breaking volume features contributions by leading international researchers exploring the social psychology of insecurity, and how existential, metaphysical and social uncertainty influence human social behaviour. Chapters in the book investigate the psychological origins of insecurity, evolutionary theorizing about the functions of insecurity, the motivational strategies people adopt to manage insecurity, self-regulation strategies, the role of insecurity in the formation and maintenance of social relationships, and the influence of insecurity and uncertainty on the organization of larger social systems and public affairs. The chapters also discuss how insecurity influences many areas of contemporary social life, highlighting the applied implications of this line of research. Topics covered include the role of insecurity in social communication, social judgments, decision making, group identification, morality, interpersonal behaviour, relationships, attitudes and many applied aspects of social life and politics where understanding the psychology of insecurity is of critical importance. This accessible and engaging book will be of interest to students, researchers and practitioners as a textbook or reference book in behavioral and social science fields, as well as to a broad spectrum of intelligent lay audience seeking to understand one of the most intriguing issues that shapes human social life.

Featuring concrete strategies and examples in both formal and informal educational settings, as well as discussion questions for teachers and students, text boxes with examples of critical education in practice, a glossary, and suggestions for further reading, Mark Wolfmeyer shows how critical mathematics education can be put into practice, relevant for undergraduate and graduate students in education, current teachers, and teacher educators.

Developed from the author's course on advanced mechanics of composite materials, Finite Element Analysis of Composite Materials with Abaqus (R) shows how powerful finite element tools tackle practical problems in the structural analysis of composites. This Second Edition includes two new chapters on "Fatigue" and "Abaqus Programmable Features" as well as a major update of chapter 10 "Delaminations" and significant updates throughout the remaining chapters. Furthermore, it updates all examples, sample code, and problems to Abaqus 2020. Unlike other texts, this one takes theory to a hands-on level by actually solving problems. It explains the concepts involved in the detailed analysis of composites, the mechanics needed to translate those concepts into a mathematical representation of the physical reality, and the solution of the resulting boundary value problems using Abaqus. The reader can follow a process to recreate every example using Abaqus graphical user interface (CAE) by following step-by-step directions in the form of pseudo-code or watching the solutions on YouTube. The first seven chapters provide material ideal for a one-semester course. Along with offering an introduction to finite element analysis for readers without prior knowledge of the finite element method (FEM), these chapters cover the elasticity and strength of laminates, buckling analysis, free edge stresses, computational micromechanics, and viscoelastic models for composites. Emphasizing hereditary phenomena, the book goes on to discuss continuum and discrete damage mechanics as well as delaminations and fatigue. The text also shows readers how to extend the capabilities of Abaqus via "user subroutines" and Python scripting. Aimed at advanced students and professional engineers, this textbook features 62 fully developed examples interspersed with the theory, 82 end-of-chapter exercises, and 50+ separate pieces of Abaqus pseudo-code that illustrate the solution of example problems. The author's website offers the relevant Abaqus and MATLAB model files available for download, enabling readers to easily reproduce the examples and complete the exercises. Video recording of solutions to examples are available on YouTube with multilingual captions.
