Book Description
Updated analysis of how the increasing polarization of American politics has been accompanied and accelerated by greater income inequality. The idea of America as politically polarized—that there is an unbridgeable divide between right and left, red and blue states—has become a cliché. What commentators miss, however, is that increasing polarization has been closely accompanied by fundamental social and economic changes—most notably, a parallel rise in income inequality. In this second edition of Polarized America, Nolan McCarty, Keith Poole, and Howard Rosenthal use the latest data to examine the relationships of polarization, wealth disparity, immigration, and other forces. They find that inequality feeds directly into political polarization, and polarization in turn creates policies that further increase inequality. Paul Krugman called the first edition of Polarized America “Important.... Essential reading for anyone who wants to understand what's happening to America.” The second edition has been thoroughly brought up to date. All statistical analyses, tables, and figures have been updated with data that run through 2012 or 2014, and the text has been revised to reflect the latest evidence. The chapter on campaign finance has been completely rewritten (with Adam Bonica as coauthor); the analysis shows that with so much “soft” money coming from very wealthy ideological extremists, there is even greater campaign contribution inequality than income inequality.

Book Description
The idea of America as politically polarized—that there is an unbridgeable divide between right and left, red and blue states—has become a cliché. What commentators miss, however, is that increasing polarization in recent decades has been closely accompanied by fundamental social and economic changes—most notably, a parallel rise in income inequality. In Polarized America, Nolan McCarty, Keith Poole, and Howard Rosenthal examine the relationships of polarization, wealth disparity, immigration, and other forces, characterizing it as a dance of give and take and back and forth causality. Using NOMINATE (a quantitative procedure that, like interest group ratings, scores politicians on the basis of their roll call voting records) to measure polarization in Congress and public opinion, census data and Federal Election Commission finance records to measure polarization among the public, the authors find that polarization and income inequality fell in tandem from 1913 to 1957 and rose together dramatically from 1977 on; they trace a parallel rise in immigration beginning in the 1970s. They show that Republicans have moved right, away from redistributive policies that would reduce income inequality. Immigration, meanwhile, has facilitated the move to the right: non-citizens, a larger share of the population and disproportionately poor, cannot vote; thus there is less political pressure from the bottom for redistribution than there is from the top against it. In "the choreography of American politics" inequality feeds directly into political polarization, and polarization in turn creates policies that further increase inequality.

Book Description
Polarized light is a pervasive influence in our world—and scientists and engineers in a variety of fields require the tools to understand, measure, and apply it to their advantage. Offering an in-depth examination of the subject and a description of its applications, Polarized Light, Third Edition serves as a comprehensive self-study tool complete with an extensive mathematical analysis of the Mueller matrix and coverage of Maxwell’s equations. Links Historical Developments to Current Applications and Future Innovations This book starts with a general description of light and continues with a complete exploration of polarized light, including how it is produced and its practical applications. The author incorporates basic topics, such as polarization by refraction and reflection, polarization elements, anisotropic materials, polarization formalisms (Mueller–Stokes and Jones) and associated mathematics, and polarimetry, or the science of polarization measurement. New to the Third Edition: A new introductory chapter Chapters on: polarized light in nature, and form birefringence A review of the history of polarized light, and a chapter on the interference laws of Fresnel and Arago—both completely re-written A new appendix on conventions used in polarized light New graphics, and black-and-white photos and color plates Divided into four parts, this book covers the fundamental concepts and theoretical framework of polarized light. Next, it thoroughly explores the science of polarimetry, followed by discussion of polarized light applications. The author concludes by discussing how our polarized light framework is applied to physics concepts, such as accelerating charges and quantum systems. Building on the solid foundation of the first two editions, this book reorganizes and updates existing material on fundamentals, theory, polarimetry, and applications. It adds new chapters, graphics, and color photos, as well as a new appendix on conventions used in polarized light. As a result, the author has re-established this book’s lofty status in the pantheon of literature on this important field.

Book Description
An Up-to-Date Compendium on the Physics and Mathematics of Polarization Phenomena Now thoroughly revised, Polarized Light and the Mueller Matrix Approach cohesively integrates basic concepts of polarization phenomena from the dual viewpoints of the states of polarization of electromagnetic waves and the transformations of these states by the action of material media. Through selected examples, it also illustrates actual and potential applications in materials science, biology, and optics technology. The book begins with the basic concepts related to two- and three-dimensional polarization states. It next describes the nondepolarizing linear transformations of the states of polarization through the Jones and Mueller-Jones approaches. The authors then discuss the forms and properties of the Jones and Mueller matrices associated with different types of nondepolarizing media, address the foundations of the Mueller matrix, and delve more deeply into the analysis of the physical parameters associated with Mueller matrices. The authors proceed with introducing the arbitrary decomposition and other useful parallel decompositions, and compare the powerful serial decompositions of depolarizing Mueller matrices. They also analyze the general formalism and specific algebraic quantities and notions related to the concept of differential Mueller matrix. Useful approaches that provide a geometric point of view on the polarization effects exhibited by different types of media are also comprehensively described. The book concludes with a new chapter devoted to the main procedures for filtering measured Mueller matrices. Suitable for advanced graduates and more seasoned professionals, this book covers the main aspects of polarized radiation and polarization effects of material media. It expertly combines physical and mathematical concepts with important approaches for representing media through equivalent systems composed of simple components.
