W. R. Dedekind. The first presents Dedekind's theory of the irrational number-the Dedekind cut idea-perhaps the most famous of several such theories created in the 19th century to give a precise meaning to irrational numbers, which had been used on an intuitive basis since Greek times. This paper provided a purely arithmetic and perfectly rigorous foundation for the irrational numbers and thereby a rigorous meaning of continuity in analysis.The second essay is an attempt to give a logical basis for transfinite numbers and properties of the natural numbers. It examines the notion of natural numbers, the distinction between finite and transfinite (infinite) whole numbers, and the logical validity of the type of proof called mathematical or complete induction.The contents of these essays belong to the foundations of mathematics and will be welcomed by those who are prepared to look into the somewhat subtle meanings of the elements of our number system. As a major work of an important mathematician, the book deserves a place in the personal library of every practicing mathematician and every teacher and historian of mathematics.

    Since its publication in 1908, it has been a classic work to which successive generations of budding mathematicians have turned at the beginning of their undergraduate courses. In its pages, Hardy combines the enthusiasm of a missionary with the rigor of a purist in his exposition of the fundamental ideas of the differential and integral calculus, of the properties of infinite series and of other topics involving the notion of limit.

    Until now, copies on the antiquarian book circuit sold for many hundreds of dollars. It is a crucial book for understanding both Mortensen’s philosophy and his use of psychology in the making of his pictures. To illustrate the text Mortensen includes an amazing gallery of his best-known and most challenging images with explanations, by him, of what makes those photographs so compelling.The reprint of The Command to Lookalso contains two new major essays that assess the significance and impact of the original book. An introduction by Mortensen biographer Larry Lytle explores Mortensen’s use of Jungian psychology and also discusses new advances in neural psychology that confirm Mortensen’s methods of controlling the viewer’s eye. The second essay, by historian Michael Moynihan (author of Lords of Chaos), details a strange and unexpected reception of the book: how this small volume on photographic methods played a role in the creation of the modern Church of Satan and Anton LaVey’s theories about Satanic Magic.

    Now fully updated and expanded by the original author, this elegant new edition is sure to become a modern staple in backpacks, kitchens, and personal libraries.A noted wild edibles authority, Doug Benoliel provides more than 65 thorough descriptions of the most common edible plants of the Pacific Northwest region, from asparagus to watercress, juneberries to cattails, and many, many more! He also includes a description of which poisonous "look-alike" plants to avoid -- a must-read for the foraging novice. Features include detailed illustrations of each plant, an illustrated guide to general plant identification principles, seasonality charts for prime harvesting, a selection of simple foraging recipes, and a glossary of botanical terms. Beginning with his botany studies at the University of Washington, Doug Benoliel has been dedicated to native plants. He has owned a landscaping, design, and nursery business, and done his extensive work with the National Outdoor Leadership School (NOLS). Doug lives on Lopez Island, Washington.

    Reginald Bray (1879-1939) was one of an ordinary middle-class Englishman quietly living out his time as an accountant in the leafy suburb of Forest Hill, London. A glimpse behind his study door, however, revealed his extraordinary passion for sending unusual items through the mail. In 1898, Bray purchased a copy of the Post Office Guide, and began to study the regulations published quarterly by the British postal authorities. He discovered that the smallest item one could post was a bee, and the largest, an elephant. Intrigued,he decided to experiment with sending ordinary and strange objects through the post unwrapped, including a turnip, abowler hat, a bicycle pump, shirt cuffs, seaweed, a clothes brush, even a rabbit's skull. He eventually posted his Irish terrier and himself (not together), earning him the name "The Human Letter." He also mailed cards to challenging addressessome in the form of picture puzzles, others sent to ambiguous recipients at hard to reach destinationsall in the name of testing the deductive powers of the beleaguered postman. Over time hispassion changed from sending curios to amassing the world's largest collection of autographs, also via the post. Starting with key British military officers involved in the Second Boer War, he acquired thousands of autographs during the first four decades of the twentieth centuryof politicians, military men, performing artists, aviators, sporting stars, and many others. By the time he died in 1939, Bray had sent out more than thirty-two thousand postal curios and autograph requests. The Englishman Who Posted Himself and Other Curious Objects tells W. Reginald Bray's remarkable tale for the first time and includes delightful illustrations of some of his most amazing postal creations. Readers will never look at the objects they post the same way again.

    The work is predicated on the idea that studying mathematics can generate the same enthusiasm as playing a team sport - without necessarily being competitive.

    From the woman suffering from "painful foot and moving toe syndrome" to the Indiana farmer who contacted a variant of mad cow disease from his herds of livestock, Klawans deduced a great deal from his patients, not only about the immediate causes of their ailments, but about the evolutionary underpinnings of their behavior.

    Divided into three sections – the movement, its fashion and advertising – the reader gains great insight into the artists and innovators that helped popularize the Art Deco movement, such as Georges Barbier, Erté, Cassandre and Paul Colin. While the main focus for this intriguing book is centred on graphic art, numerous examples of other forms of Art Deco are also featured. Nestled among the posters and paintings, sculpture, objets d'art and jewellery assert their similarity, whether through line, form or theme. These echoes serve to show the creativity fertility of the period as styles and ideas traversed artistic media.

    They'll also find the related analytic geometry much easier. The clear review of algebra and geometry in this edition will make calculus easier for students who wish to strengthen their knowledge in these areas. Updated to meet the emphasis in current courses, this new edition of a popular guide--more than 104,000 copies were bought of the prior edition--includes problems and examples using graphing calculators..

    Loren Rhoads, creator and editor of the magazine, has compiled some of her favorite stories from all ten issues in this sometimes shocking, occasionally gruesome, always fascinating anthology. This quirky book is filled with tales from ordinary people -- who just happen to have eccentric, peculiar interests. Ranging from the outrageous (attending a Black Mass, fishing bodies out of San Francisco Bay, making fake snuff films) to the more "mundane" (visiting a torture museum, tracking real vampires through San Francisco), this curiously enjoyable collection of stories, complete with illustrations and informative asides, will entertain and haunt readers long after the final page is turned.
