In the early nineteenth century, a French sociologist and political scientist undertook a seven-month journey throughout the newly formed United States. Alexis de Tocqueville surveyed the young nation's religious, political, and economic character and reported his findings in two volumes, published in 1835 and 1840. Two centuries later, Democracy in America remains among the most astute and influential surveys of American politics and society. de Tocqueville focuses on why republican representative democracy prevailed in the United States, tracing its success from the state of equality established by the early Puritan settlers through the American Revolution and adoption of the Constitution. His speculations on the future of democracy offer prescient, thought-provoking reading, and his classic work remains a touchstone for modern thinkers on government. This edition is based on the earliest approved translation, which has served as the standard version for over a century and comes closest to reflecting the author's insights as perceived by his contemporaries. www.doverpublications.com

Ilya Prigogine won the 1977 Nobel Prize in Chemistry for his contributions to non-equilibrium thermodynamics. This groundbreaking 1962 monograph, written for researchers and graduate students in this field, was his first book-length contribution to this subject. Suitable for advanced undergraduates and graduate students in physics and chemistry, the treatment begins with examinations of the Liouville equation, anharmonic solids, and Brownian motion. Subsequent chapters explore weakly coupled gases, scattering theory and short-range forces, distribution functions and their diagrammatic representation, the time dependence of diagrams, the approach to equilibrium in ionized gases, and statistical hydrodynamics. Additional topics include general kinetic equations, general H-theorem, quantum mechanics, and irreversibility and invariants of motion. Appendices, a bibliography, list of symbols, and an index conclude the text.Dover (2017) republication of the edition originally published by Interscience Publishers, New York, 1962.www.doverpublications.com

The clarity of the author's thought and the carefulness of his exposition make reading this book a pleasure, noted the Bulletin of the American Mathematical Society upon the 1955 publication of John L. Kelley's General Topology. This comprehensive treatment for beginning graduate-level students immediately found a significant audience, and it remains a highly worthwhile and relevant book for students of topology and for professionals in many areas. A systematic exposition of the part of general topology that has proven useful in several branches of mathematics, this volume is especially intended as background for modern analysis. An extensive preliminary chapter presents mathematical foundations for the main text. Subsequent chapters explore topological spaces, the Moore-Smith convergence, product and quotient spaces, embedding and metrization, and compact, uniform, and function spaces. Each chapter concludes with an abundance of problems, which form integral parts of the discussion as well as reinforcements and counter examples that mark the boundaries of possible theorems. The book concludes with an extensive index that provides supplementary material on elementary set theory.Dover (2017) republication of the edition published by the Van Nostrand Reinhold Company, New York, 1955.www.doverpublications.com

Attorney G. E. M. Skues drew upon his vast experience as a recreational fisherman to write this masterpiece of the fly fishing genre, in which he established sunken flies as essential tools for the well-equipped angler. Originally published in 1921, this seminal book retains its relevance in a world in which the quiet pleasures of river fishing remain unchanged. Professional, competitive, and amateur fishermen as well as beginners will appreciate its timeless wisdom.British fly fishing historian Dr. Andrew Herd hailed the author as "without any doubt one of the greatest trout fishermen that ever lived. His achievement was the invention of fly fishing with the nymph, a discovery that put a full stop to half a century of stagnation in wet fly fishing for trout, and formed the bedrock for modern sunk fly fishing." Paul Schullery, an American fly fishing historian, seconds this view, adding, "[Skues] was also a modest, humorous, and warmly accessible writer whose writings never lost sympathy for his fellow anglers. His self-deprecating and deceptively simple-sounding writings on trout and fly fishing remain among the wisest and most revealing in the sport's enormous literature."www.doverpublications.com
