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.

Computational Complexity Theory is the study of how much of a given resource is required to perform the computations that interest us the most. Four decades of fruitful research have produced a rich and subtle theory of the relationship between different resource measures and problems. At the core of the theory are some of the most alluring open problems in mathematics. This book presents three weeks of lectures from the IAS/Park City Mathematics Institute Summer School on computational complexity. The first week gives a general introduction to the field, including descriptions of the basic mo.

In a very short time, lasers advanced from research interest to increasingly useful, commercially available tools for material processing, precision measurements, surgery, communication, and even entertainment. This 1996 book provides the background in theoretical physics necessary to understand engineering applications. It summarises relevant theories of geometrical optics, physical optics, quantum optics, and laser physics and ties them to applications in such areas as fluid mechanics, combustion, surface analysis, material processing and laser machining. Advanced topics such as laser Doppler velocimetry, laser-induced fluorescence, and holography are clearly and thoroughly explained. The book includes numerous examples and homework problems. A unique feature is the advanced research problems in each chapter that simulate real-world research and encourage independent reading and analysis.

Discusses the fundamental principles of the design and development of microwave satellite switches utilized in military, commercial, space, and terrestrial communication This book deals with important RF/microwave components such as switches and phase shifters, which are relevant to many RF/microwave applications. It provides the reader with fundamental principles of the operation of some basic ferrite control devices and explains their system uses. This in-depth exploration begins by reviewing traditional nonreciprocal components, such as circulators, and then proceeds to discuss the most recent advances. This sequential approach connects theoretical and scientific characteristics of the devices listed in the title with practical understanding and implementation in the real world. Microwave Polarizers, Power Dividers, Phase Shifters, Circulators and Switches covers the full scope of the subject matter and serves as both an educational text and resource for practitioners. Among the many topics discussed are microwave switching, circular polarization, planar wye and equilateral triangle resonators, and many others. Translates concepts and ideas fundamental to scientific knowledge into a more visual description Describes a wide array of devices including waveguides, shifters, and circulators Covers the use of finite element algorithms in design Microwave Polarizers, Power Dividers, Phase Shifters, Circulators and Switches is an ideal reference for all practitioners and graduate students involved in this niche field.

This textbook reduces the complexity of the coverage of optics to allow a student with only elementary calculus to learn the principles of optics and the modern Fourier theory of diffraction and imaging. Students majoring in sciences or engineering and taking a standard physics course on optics will find this text useful. Examples of a variety of applications dependent on optics allow the student to connect this course to their particular field of interest. Topics covered include aberrations with experimental examples, correction of chromatic aberration, explanation of coherence and the use of interference theory to design an antireflection coating. Fourier transform optics and its application to diffraction and imaging, use of Gaussian wave theory, and fiber optics make the text of interest to those in electrical and bioengineering as well as physics and medical science. The text includes hundreds of photos, figures and diagrams to provide readers with strong visual insights into optics. More difficult, optional topics are highlighted throughout, and the need for experience with differential equations and extensive use of vector theory are avoided by using a one dimensional theory where possible. Maxwell's equations are introduced only to determine the properties of a light wave, and the boundary conditions are introduced to characterize reflection and refraction. Most discussion is limited to reflection. The book also introduces Fourier transforms as they are needed in the discussion of diffraction and imaging.

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.
