Описание: Chichen Itza, the legendary capital and trading hub of the late Maya civilization, continues to fascinate visitors and researchers with unanswered questions about its people, rulers, rituals, and politics. Addressing many of these current debates, Landscapes of the Itza asks when the city’s construction was completed, what the purposes of its famous pyramid and other buildings were, how the city’s influence was felt in smaller neighboring settlements, and whether the city maintained strict territorial borders. Special attention is given to the site’s visual culture, including its architecture, ceramics, sculptures, and murals. This volume is a much-needed update on recent archaeological and art historical work being done at Chichen Itza, offering new ways of understanding the site and its role in the Yucatan landscape.

Описание: The famous and prolific nineteenth-century mathematician, engineer and inventor Charles Babbage (1791–1871) was an early pioneer of computing. He planned several calculating machines, but none was built in his lifetime. On his death his youngest son, Henry P. Babbage, was charged with the task of completing an unfinished volume of papers on the machines, which was finally published in 1889 and is reissued here. The papers, by a variety of authors, were collected from journals including The Philosophical Magazine, The Edinburgh Review and Scientific Memoirs. They relate to the construction and potential application of Charles Babbage's calculating engines, notably the Difference Engine and the more complex Analytical Engine, which was to be programmed using punched cards. The book also includes correspondence with members of scientific societies, as well as proceedings, catalogues and drawings. Included is a complete catalogue of the drawings of the Analytical Engine.
