Free Download Join Geometries: A Theory of Convex Sets and Linear Geometry by Walter Prenowitz , James Jantosciak English | PDF | 1979 | 554 Pages | ISBN : 1461394406 | 76.7 MB The main object of this book is to reorient and revitalize classical geometry in a way that will bring it closer to the mainstream of contemporary mathematics. The postulational basis of the subject will be radically revised in order to construct a broad-scale and conceptually unified treatment. The familiar figures of classical geometry-points, segments, lines, planes, triangles, circles, and so on-stem from problems in the physical world and seem to be conceptually unrelated. However, a natural setting for their study is provided by the concept of convex set, which is compara tively new in the history of geometrical ideas. The familiarfigures can then appear as convex sets, boundaries of convex sets, or finite unions of convex sets. Moreover, two basic types of figure in linear geometry are special cases of convex set: linear space (point, line, and plane) and halfspace (ray, halfplane, and halfspace). Therefore we choose convex set to be the central type of figure in our treatment of geometry. How can the wealth of geometric knowledge be organized around this idea? By defini tion, a set is convex if it contains the segment joining each pair of its points; that is, if it is closed under the operation of joining two points to form a segment. But this is precisely the basic operation in Euclid.  Free Download John Williams: A Composer's Life by Tim Greiving English | September 2, 2025 | ISBN: 0197620884 | True EPUB/PDF | 640 pages | 40.4/61.7 MB The first biography of a great American composer of the cinema age  Free Download John Ruskin (Critical Lives) by Andrew Ballantyne English | September 15, 2015 | ISBN: 1780234295 | True EPUB | 252 pages | 6.1 MB John Ruskin (1819-1900) was the most prominent art and architecture critic of his time. Yet his reputation has been overshadowed by his personal life, especially his failed marriage to Effie Gray, which has cast him in the history books as little more than a Victorian prude. In this book, Andrew Ballantyne rescues Ruskin from the dustbin of history's trifles to reveal a deeply attuned thinker, one whose copious writings had tremendous influence on all classes of society, from roadmenders to royalty.  Free Download John Candy: A Life in Comedy by Paul Myers English | October 7, 2025 | ISBN: 1487009526 | True EPUB | 376 pages | 2.15 MB From the bestselling author of Kids in the Hall: One Dumb Guy, the definitive biography of John Candy―a heartwarming portrait of one of comedy's most beloved and enduring stars.  Free Download John Cage (Critical Lives) by Rob Haskins English | June 15, 2012 | ISBN: 186189905X | True EPUB | 180 pages | 4.3 MB American writer, composer, artist, and philosopher John Cage (1912-92) is best known for his experimental composition 4'33," a musical score in which the performer does not play an instrument during the duration of the piece. The purpose, Cage said, was for the audience to listen to the sounds of the environment around them while the piece was performed. Groundbreaking pieces such as 4'33", as well as Sonatas and Interludes not only established Cage as a leading figure in the postwar avant-garde movement, but also cemented the enduring controversy surrounding his work.

Free Download Japan's Colonialism and Indonesia by M. A. Aziz English | PDF | 1955 | 282 Pages | ISBN : 940118500X | 26.5 MB The rise and fall of the Japanese empire constitutes one of the most dramatic episodes of modern history. Within the short span of fifty years Japan grew out of political backwardness into a position of tremendous power. Japan's rise to power challenged Europe's hegemony over Asia, but, paradoxically, it was Japan's fall that caused the irreparable ruin of the colonial system over Eastern lands. Japan went to war against the West under the battlecry of Asia's liberation from European colonialism. In reality, for forty years, beginning with her first war against China, she had striven to imitate this colonialism, as she had endeavoured to imitate the political, military and economic achievements of Europe. A thorough understanding of the imitative character of the Japanese Empire might well have induced the leaders of the nation to side with the conservative trend of political thought in the Western world in order to maintain the existing world-wide political system of which colonial rule was an accepted part. They might have understood that an adventurous, revolutionary policy was bound to result in grave dangers for their own state and most conservative structure. Japan might have continued to grow and to expand if she had succeeded to play the role of the legitimate heir to Europe's decaying power in Asia. By violently opposing that power, she undermined the very foun dations of her own rule outside the home-islands.

This book critically examines this enduring phenomenon, exploring the privileged position of Italian architects, architecture, and cities in the architectural culture of the past century. |
