<p><div> <div> <p>The long agony of the American Civil War inspired a wealth of contemporary verse -- from sentimental doggerel to sublime lyrics that rank among the finest American poetry. This inexpensive anthology brings together a superb selection of poems from both North and South, comprising the best and most representative poetry of those turbulent times.<br /> Over 75 poems include works by many of America's greatest 19th century writers: Walt Whitman, Herman Melville, Ralph Waldo Emerson, Henry Wadsworth Longfellow, John Greenleaf Whittier, William Cullen Bryant, and many more. Also included are many fine poems by lesser-known poets of the period: Julia Ward Howe, Henry Timrod, Edwin Markham, Edmund Clarence Stedman, Francis Miles Finch, George Henry Boker, and more.<br /> Among the selections in this volume: Julia Ward Howe's "Battle Hymn of the Republic," Ralph Waldo Emerson's "Boston Hymn," John Greenleaf Whittier's "Barbara Frietchie," "The Death of Slavery," by William Cullen Bryant, Henry Wadsworth Longfellow's "Killed at the Ford," Henry Howard Brownell's "The Bay Flight," "All Quiet Along the Potomac Tonight" by Ethel Lynn Beers, "O Captain! My Captain!" and "When Lilacs Last in the Dooryard Bloom'd" by Walt Whitman, and many more.<br /> Ranging from boisterous calls to arms to poignant memorials for the slain, these poems reflect the heroism, horror, exaltation, and anguish of the bloodiest and most crucial conflict in the nation's history. Anyone interested in the Civil War or American literature of the period will want this collection on their bookshelves.<br /> <br /></p> </div> </div></p>

<p><div> <div>Here is Poincaré's famous discussion of creative psychology as it is revealed in the physical sciences. Explaining how such basic concepts as number and magnitude, space and force were developed, the great French mathematician refutes the skeptical position that modern scientific method and its results are wholly factitious. The places of rigorous logic and intuitive leaps are both established by an analysis of contrasting methods of idea-creation in individuals and in modern scientific traditions. The nature of hypothesis and the role of probability are investigated with all of Poincaré's usual fertility of insight.<br /> Partial contents: On the nature of mathematical reasoning. Magnitude and experiment. Space: non-Euclidean geometrics, space and geometry, experiment and geometry. Force: classical mechanics, relative and absolute motion, energy and thermodynamics. Nature: hypotheses in physics, the theories of modern physics, the calculus of probabilities, optics and electricity, electro-dynamics.<br /> "Poincaré's was the last man to take practically all mathematics, both pure and applied as his province. Few mathematicians have had the breadth of philosophic vision that Poincaré's had, and none is his superior in the gift of clear exposition." -- <i>Men of Mathematics</i>, Eric Temple Bell, Professor of Mathematics, University of Cambridge</div> </div></p>

Henri, Poincaré

<p><div> <div>"Klein is both a skilled reporter and a wide-ranging humanistic scholar. The book is popular and learned, witty and serious, literary and mathematical -- always solid and entertaining." -- <i>Los Angeles Times.<br /></i>Although the topic of measurement might seem to lend itself to a dry-as-dust treatment, this book is just the opposite: an engrossing, easy-to-read study that treats a multifaceted topic with wit, imagination, and wide-ranging scholarship.</div> <div>Metrology, the science of measurement, usually concerns itself with length, weight, volume, temperature, and time, but in this comprehensive work the topic also encompasses nuclear radiation, thermal power, light, pressure, sound, and many other areas.<br /> Representing nearly ten years of research effort, <i>The Science of Measurement</i> is considered a definitive book on the concepts and units by which we measure everything in our universe. Nontechnical in its approach, it is not only completely accessible to the general reader but as entertaining and fun to read as it is informative and comprehensive.<br /> " . . . not concerned only with problems of measuring the limits of space or the size of the proton. It is filled with interesting digressions. Not a book for daydreaming, but a book for the curious. Klein's survey of the units and concepts by which we measure everything in the universe helps us understand that universe much better." -- <i>Boston Herald Advertiser</i></div> </div></p>

The World's Lighthouses: From Ancient Times to 1820

<p>The most important work ever produced in the field of physiological optics, this classic is a model of scientific method and logical procedure, and it remains unmatched in its thorough and accessible approach.<BR>This is the third in a three-volume republication of the definitive English translation of "Handbuch der Physiologischen Optik, " originally published by The Optical Society of America in 1924 and containing everything that was known about physiological optics up until that time. The substratum consists of the data that Helmholtz furnished in the two nineteenth-century German editions that appeared during his lifetime. These volumes also contain extensive supplementary matter that Nagel, Gullstrand, and Kries incorporated in the third German edition of 1911, as well as significant new material prepared for the 1924 English translation by C. Ladd-Franklin, Gullstrand, and Kries, with copious annotations by James P. C. Southall that brought the work up to date with current research.<BR>Volumes I and II discuss the dioptrics of the eye and the sensations of vision;Volume III examines the perceptions of vision. Its topics include eye movements; the monocular field of vision; direction of vision; perception of depth; binocular vision; and many other highly important topics. Appendixes cover later findings on spatial configuration in vision and the theory of binocular instruments. Indexes for all three volumes are organized by subject and author.</p>

Treatise on Physiological Optics, Volume III

Hermann von Helmholtz

Written by one of the great historians of our generation, this unusal volume describes the birth and growth of one of the most important basic ideas of our civilization: progress, or the concept that men are advancing in a definite and desirable direction.Dr. Bury does not attempt to evaluate the "truth" of the idea of progress. He does, however, demonstrate how important this idea has been as a motivating force in modern history. Unabridged reissue.
