Quartz and Its Varieties


Book Description

Excerpt from Quartz and Its Varieties: Including Rock Crystal, Amethyst, Agate, Jasper, Agatized Wood, Smoky Quartz With a Description of Localities Quartz and its Varieties was printed in parts, beginning in the June and ending in the December, 1895, number of The Mineral Collector. In writing the articles, my aim has been to describe in detail the famous old localities which still afford specimens of the mineral, the more recently discovered and little known localities, and the character of the material found at each of them. I have avoided, as far as possible, mention of the exhausted localities, or those which have afforded a very limited supply of specimens, even though they were of exceptional interest. I realize that many localities worth recording have not been mentioned, for the reason that the facts relating to them were not accessible to me. The editor of The Mineral Collector, Mr. Chamberlain, and the few collectors who have expressed an opinion relative to the matter, believe that if the articles were printed in pamphlet form, they would be acceptable to collectors generally. Because of the arrangement of the localities, an index is not considered necessary. I shall be glad to be informed of any American localities affording quartz or any of its varieties, not fully mentioned in the following pages.

The Contribution of Mineralogy to Cultural Heritage


Book Description

The chapters contributed to this book recognize the important and diverse contributions of mineralogy to the valorization, characterization, interpretation and conservation of cultural heritage. The book focuses on examples of materials and methodological issues rather than technical/analytical details.







Buyology


Book Description

NEW YORK TIMES BESTSELLER • “A fascinating look at how consumers perceive logos, ads, commercials, brands, and products.”—Time How much do we know about why we buy? What truly influences our decisions in today’s message-cluttered world? In Buyology, Martin Lindstrom presents the astonishing findings from his groundbreaking three-year, seven-million-dollar neuromarketing study—a cutting-edge experiment that peered inside the brains of 2,000 volunteers from all around the world as they encountered various ads, logos, commercials, brands, and products. His startling results shatter much of what we have long believed about what captures our interest—and drives us to buy. Among the questions he explores: • Does sex actually sell? • Does subliminal advertising still surround us? • Can “cool” brands trigger our mating instincts? • Can our other senses—smell, touch, and sound—be aroused when we see a product? Buyology is a fascinating and shocking journey into the mind of today's consumer that will captivate anyone who's been seduced—or turned off—by marketers' relentless attempts to win our loyalty, our money, and our minds.




Silica


Book Description

Volume 29 of Reviews in Mineralogy provides an updated silica review which focuses on the most recent developments. This book describes the crystal structures and phase transitions of silica and its stuffed derivatives; bridges the relationship between the microstructural character of real silica minerals and the behavior of silica in the geological environment; covers Quantum mechanical considerations of the Si-O bond; shows how calculations based upon first-principles theory can explain and predict silica transitions at high temperatures and pressures; covers spectroscopic analyses of silica and how they reveal vibrational behaviors in response to variations in temperature, pressure, and composition and finally details the uses of silica for industrial purposes.







The World of Opals


Book Description

Readers will find fascinating details about the discovery, whereabouts, and value of famous opals, from such classic specimens as the Burning of Troy Opal to the Bonanza Opal and other more recent discoveries. Finally, the book surveys today's major opal-producing areas and provides current information on opal occurrence worldwide. Punctuating the text are useful tables, extensive glossaries of opal types and opal-related terms, and beautiful photographs that capture the essence and mystery of this most exquisite stone.




Wealth of the World's Waste Places, and Oceania


Book Description

Although the term "Waste Places" carries an implied meaning of "worthless," yet, interpreted in the light of Nature's methods, each region described, useless as it may apparently seem, possesses a definite relation to the rest of the world, and therefore to the well-being of man. The Sahara is the track of the winds whose moisture fertilizes the flood-plains of the Nile. The Himalaya Mountains condense the rain that gives life to India. From the inhospitable polar regions come the winds and currents that temper the heat of the tropics.
