It presents the important traditional content of mineralogy including crystallography, chemical bonding, controls on mineral structure, mineral stability, and crystal growth to provide a foundation that enables students to understand the nature and occurrence of minerals. Physical, optical, and X-ray powder diffraction techniques of mineral study are described in detail, and common chemical analytical methods are outlined as well. Detailed descriptions of over 100 common minerals are provided, and the geologic context within which these minerals occur is emphasized. Appendices provide tables and diagrams to help students with mineral identification, using both physical and optical properties. Numerous line drawings, photographs, and photomicrographs help make complex concepts understandable. Introduction to Mineralogy not only provides specific knowledge about minerals but also helps students develop the intellectual tools essential for a solid, scientific education. This comprehensive text is useful for undergraduate students in a wide range of mineralogy courses.

    

    Many have written about the evolution of our grammar, pronunciation, and vocabulary, but only Lerer situates these developments in the larger history of English, America, and literature.Lerer begins in the seventh century with the poet Caedmon learning to sing what would become the earliest poem in English. He then looks at the medieval scribes and poets who gave shape to Middle English. He finds the traces of the Great Vowel Shift in the spelling choices of letter writers of the fifteenth century and explores the achievements of Samuel Johnson's Dictionary of 1755 and The Oxford English Dictionary of the late nineteenth and early twentieth centuries. He describes the differences between English and American usage and, through the example of Mark Twain, the link between regional dialect and race, class, and gender. Finally, he muses on the ways in which contact with foreign languages, popular culture, advertising, the Internet, and e-mail continue to shape English for future generations.Each concise chapter illuminates a moment of invention-a time when people discovered a new form of expression or changed the way they spoke or wrote. In conclusion, Lerer wonders whether globalization and technology have turned English into a world language and reflects on what has been preserved and what has been lost. A unique blend of historical and personal narrative, Inventing English is the surprising tale of a language that is as dynamic as the people to whom it belongs.
