One of the world's leading experts on gemstones and photomicrography, Eduard Josef Gubelin (1913-2005) acquired an outstanding international reputation from his collection of precious stones and his scientific contributions. His lifelong study of inclusions in gemstones dramatically altered the field of gemology forever and laid the foundation for the microscopic identification of many new types of gemstones. In addition to his scientific work, Gubelin also amassed a remarkable collection of gemstones, which was bought by the Gemological Institute of America, and he spent his life as a keenly active participant in art and film. Written by several of his family members, "The Eduard Josef G""u""belin Story "delves deeply into Gubelin's life story and explores how his early years laid the foundation for his extraordinary gemologist career, his research, and his legacy.

Why has Myanmar (Burma), a country rich in resources - rice, timber, minerals - descended to 'least developed country' status? Is the explanation to be found inside Burma or beyond? Is the failure of development due to political authoritarianism and conflict? Or perhaps the drugs trade is partly to blame? This book contends that all these factors have contributed. But it also maintains that the mismanagement of the country's resources is of equal, or even greater, importance. A clear answer to the question of Burma's developmental failure is sought by focussing upon the misuse of resources in concert with those factors that are more usually emphasized.
