Diamonds
A lavishly illustrated, in-depth early history covering two thousand years of diamond jewelry and commerce, from the Indian mines to European merchants, courts, and workshops This richly illustrated history of diamonds illuminates myriad facets of the “king of gems,” including a cast of larger-than-life characters such as Alexander the Great, the Mughal emperor Jahangir, and East India Company adventurers. It’s an in-depth study tracing the story of diamonds from their early mining and trade more than two thousand years ago to the 1700s, when Brazil displaced India as the world’s primary diamond supplier. Jack Ogden, a historian and gemologist specializing in ancient gems and jewelry, describes the early history of diamond jewelry, the development of diamond cutting, and how diamonds were assessed and valued. The book includes more than one hundred captivating images, from close-up full-color photographs of historic diamond-set jewelry (some previously unpublished), to photomicrographs of individual gems and illustrations of medieval manuscripts, as well as diagrams depicting historical methods of cutting and polishing diamonds.
Giuseppe Campani, “Inventor Romae,” an Uncommon Genius
Giuseppe Campani, “Inventor Romae,” an Uncommon Genius offers an account of the life and creations of the most talented maker of optic lenses, silent clocks and projector clocks of the second half of the seventeenth century but also provides you with unique insights into the scientific and technological landscape of baroque Rome and its links to a broader European scene.
Theory of Parallel Mechanisms
This book contains mechanism analysis and synthesis. In mechanism analysis, a mobility methodology is first systematically presented. This methodology, based on the author's screw theory, proposed in 1997, of which the generality and validity was only proved recently, is a very complex issue, researched by various scientists over the last 150 years. The principle of kinematic influence coefficient and its latest developments are described. This principle is suitable for kinematic analysis of various 6-DOF and lower-mobility parallel manipulators. The singularities are classified by a new point of view, and progress in position-singularity and orientation-singularity is stated. In addition, t...
