Why We're Polarized by Ezra Klein Pdf

ONE OF BARACK OBAMA’S FAVORITE BOOKS OF 2022 One of Bill Gates’s “5 books to read this summer,” this New York Times and Wall Street Journal bestseller shows us that America’s political system isn’t broken. The truth is scarier: it’s working exactly as designed. In this “superbly researched” (The Washington Post) and timely book, journalist Ezra Klein reveals how that system is polarizing us—and how we are polarizing it—with disastrous results. “The American political system—which includes everyone from voters to journalists to the president—is full of rational actors making rational decisions given the incentives they face,” writes political analyst Ezra Klein. “We are a collection of functional parts whose efforts combine into a dysfunctional whole.” “A thoughtful, clear and persuasive analysis” (The New York Times Book Review), Why We’re Polarized reveals the structural and psychological forces behind America’s descent into division and dysfunction. Neither a polemic nor a lament, this book offers a clear framework for understanding everything from Trump’s rise to the Democratic Party’s leftward shift to the politicization of everyday culture. America is polarized, first and foremost, by identity. Everyone engaged in American politics is engaged, at some level, in identity politics. Over the past fifty years in America, our partisan identities have merged with our racial, religious, geographic, ideological, and cultural identities. These merged identities have attained a weight that is breaking much in our politics and tearing at the bonds that hold this country together. Klein shows how and why American politics polarized around identity in the 20th century, and what that polarization did to the way we see the world and one another. And he traces the feedback loops between polarized political identities and polarized political institutions that are driving our system toward crisis. “Well worth reading” (New York magazine), this is an “eye-opening” (O, The Oprah Magazine) book that will change how you look at politics—and perhaps at yourself.

Nuclear Physics with Polarized Particles by Hans Paetz gen. Schieck Pdf

The measurement of spin-polarization observables in reactions of nuclei and particles is of great utility and advantage when the effects of single-spin sub-states are to be investigated. Indeed, the unpolarized differential cross-section encompasses the averaging over the spin states of the particles, and thus loses details of the interaction process. This introductory text combines, in a single volume, course-based lecture notes on spin physics and on polarized-ion sources with the aim of providing a concise yet self-contained starting point for newcomers to the field, as well as for lecturers in search of suitable material for their courses and seminars. A significant part of the book is devoted to introducing the formal theory—a description of polarization and of nuclear reactions with polarized particles. The remainder of the text describes the physical basis of methods and devices necessary to perform experiments with polarized particles and to measure polarization and polarization effects in nuclear reactions. The book concludes with a brief review of modern applications in medicine and fusion energy research. For reasons of conciseness and of the pedagogical aims of this volume, examples are mainly taken from low-energy installations such as tandem Van de Graaff laboratories, although the emphasis of present research is shifting to medium- and high-energy nuclear physics. Consequently, this volume is restricted to describing non-relativistic processes and focuses on the energy range from astrophysical energies (a few keV) to tens of MeV. It is further restricted to polarimetry of hadronic particles.

Polarized and Demobilized by Dana El Kurd Pdf

After the 1994 Oslo Accords, Palestinians were hopeful that an end to the Israeli occupation was within reach, and that a state would be theirs by 1999. With this promise, international powers became increasingly involved in Palestinian politics, and many shadows of statehood arose in the territories. Today, however, no state has emerged, and the occupation has become more entrenched. Concurrently, the Palestinian Authority has become increasingly authoritarian, and Palestinians ever more polarized and demobilized. Palestine is not unique in this: international involvement, and its disruptive effects, have been a constant across the contemporary Arab world. This book argues that internationally backed authoritarianism has an effect on society itself, not just on regime-level dynamics. It explains how the Oslo paradigm has demobilized Palestinians in a way that direct Israeli occupation, for many years, failed to do. Using a multi-method approach including interviews, historical analysis, and cutting-edge experimental data, Dana El Kurd reveals how international involvement has insulated Palestinian elites from the public, and strengthened their ability to engage in authoritarian practices. In turn, those practices have had profound effects on society, including crippling levels of polarization and a weakened capacity for collective action.

Optical Polarization in Biomedical Applications by Valery V. Tuchin,Lihong Wang,Dmitry A. Zimnyakov Pdf

Optical Polarization in Biomedical Applications introduces key developments in optical polarization methods for quantitative studies of tissues, while presenting the theory of polarization transfer in a random medium as a basis for the quantitative description of polarized light interaction with tissues. This theory uses the modified transfer equation for Stokes parameters and predicts the polarization structure of multiple scattered optical fields. The backscattering polarization matrices (Jones matrix and Mueller matrix) important for noninvasive medical diagnostic are introduced. The text also describes a number of diagnostic techniques such as CW polarization imaging and spectroscopy, polarization microscopy and cytometry. As a new tool for medical diagnosis, optical coherent polarization tomography is analyzed. The monograph also covers a range of biomedical applications, among them cataract and glaucoma diagnostics, glucose sensing, and the detection of bacteria.

Polarized by James E. Campbell Pdf

An eye-opening look at how and why America has become so politically polarized Many continue to believe that the United States is a nation of political moderates. In fact, it is a nation divided. It has been so for some time and has grown more so. This book provides a new and historically grounded perspective on the polarization of America, systematically documenting how and why it happened. Polarized presents commonsense benchmarks to measure polarization, draws data from a wide range of historical sources, and carefully assesses the quality of the evidence. Through an innovative and insightful use of circumstantial evidence, it provides a much-needed reality check to claims about polarization. This rigorous yet engaging and accessible book examines how polarization displaced pluralism and how this affected American democracy and civil society. Polarized challenges the widely held belief that polarization is the product of party and media elites, revealing instead how the American public in the 1960s set in motion the increase of polarization. American politics became highly polarized from the bottom up, not the top down, and this began much earlier than often thought. The Democrats and the Republicans are now ideologically distant from each other and about equally distant from the political center. Polarized also explains why the parties are polarized at all, despite their battle for the decisive median voter. No subject is more central to understanding American politics than political polarization, and no other book offers a more in-depth and comprehensive analysis of the subject than this one.

Birefringent Thin Films and Polarizing Elements by Ian J. Hodgkinson,Qi hong Wu Pdf

This book describes the propagation of light in biaxial media, the properties of biaxial thin films, and applications such as birefringent filters for tuning the wavelength of dye lasers.A novel feature of the first part is the parallel treatment of Stokes, Jones, and Berreman matrix formalisms in a chapter-by-chapter development of wave equations, basis vectors, transfer matrices, reflection and transmission equations, and guided waves. Computational tools for MATLAB are included.The second part focuses on an emerging planar technology in which anisotropic microstructures are formed by oblique deposition in vacuum. Methods for characterizing dielectric and metal films are discussed. Topics such as form birefringence, effective medium theory, anisotropic scatter and anisotropic fluid transport are discussed in detail.Practical applications of bulk and layered birefringent media are considered in the final part. Separate chapters are devoted to linear polarizers, phase retarders, and birefringent filters. Traditional bulk-media polarizing elements are included and compared with thin film designs.
