Girard Desargues, the architectural and perspective geometry: a study in the rationalization of figureSchneider, Mark E. January 1983 (has links)
Girard Desargues (1951-1662) was a key figure in the transformation of architectural geometry from its ancient and venerated status as transcendental knowledge and supreme reality to a mere technological instrument for the control of building construction practice. As a friend of Rene Descartes and Marin Mersenne, Desargues participated in the development of the mechanistic worldview which accompanied the emergence of experimental science and the renewed interest in mathematics and geometry as axiomatic, deductive systems.
This dissertation examines in detail Desargues' methods of stereotomy (the geometrical basis of architectural stone cutting) and his system of perspective construction without vanishing points beyond the picturespace. Desargues' theorem and other key discoveries for which he is still known in the history of mathematics are discussed as they bear upon his methods of stereotomy and perspective. Desargues' stereotomy is almost certainly the first attempt at a universal descriptive geometry such as Gaspard Monge finally developed after the French revolution. Desargues' work in this area may thus be seen as a precocious foreshadowing of the engineering geometry in common use today.
The writings of Desargues have been consulted in the original French. Extensive passages are quoted and translated, and a number of illustrations from the original texts are reproduced. Supplementary illustrations are also provided. Appendices list the known architectural works of Desargues, his writings and those of his friend and student Bosse which bear upon the exposition of Desargues' methods. / Ph. D.

Poverty and environment : a case study of stone crushing as a sustainable livelihood in LusakaNyumbu, Mutande Elizabeth 06 1900 (has links)
Poverty and the environment are closely linked, as people use environmental resources to support livelihoods. Illegal stone quarrying evident in Lusaka, Zambia is symbolic of the use of environmental resources by the poor. Stone crushing provides income yet it is characterized by land degradation, large-scale excavation and dumping of waste materials. This study provides an analytical account of stone crushing as a livelihood in Lusaka and makes recommendations for improving the livelihoods of stone crushers to become sustainable. Using a livelihoods approach, a qualitative study collected data from various role players in Lusaka. Assets (physical, natural, human, social and political capital) for stone crushers were assessed, revealing that stone crushers lack livelihood assets, key options and are exposed to various shocks due to seasonal shifts. Increasing access to key livelihood assets, reducing vulnerability, improving infrastructure, access to justice and tackling social exclusion and gender inequality will enhance their livelihoods. / Development Studies / M.A. (Development Studies)

Stories in Stone: Interpreting history in the context of a museum exhibitionHamalainen, Bonnie 01 January 2005 (has links)
This project examines opportunities for history exhibition design practices. Research into museum studies and creative work in typography, photography, graphic design and architecture result in curation and design of a prototypical exhibit about the granite quarrying industry of Stonington, Maine.
