Geneticists/people of metal at the University of Nairobi conduct a centuries-long genetic engineering initiative that transforms biological Africans into an entirely new, immeasurably smarter human species. Meanwhile, the people of metal who led the Human Rescue Initiative in Africa have built human colonies on two distant planets to assure that humans survive somewhere. Colonists find strange mosaic-like formations of small stones at ground level on both planets. They form identical patterns that change in a fixed sequence. It's a coded message that promises God's overwhelming love to the message's recipients if they can formally prove an "unsolvable" 20th-century math conjecture and send the proof in the direction of "God's abode." African leaders treat the message as genuine, just in case. God's love is nothing to sneeze at, if He exists. Contemporary mathematicians aren't yet smart enough to solve the conjecture, but it's only a matter of time, and genetics.

First published in 1996, All the Nations Under Heaven has earned praise and a wide readership for its unparalleled chronicle of the role of immigrants and migrants in shaping the history and culture of New York City. This updated edition of a classic text brings the story of the immigrant experience in New York City up to the present with vital new material on the city’s revival as a global metropolis with deeply rooted racial and economic inequalities. All the Nations Under Heaven explores New York City’s history through the stories of people who moved there from countless places of origin and indelibly marked its hybrid popular culture, its contentious ethnic politics, and its relentlessly dynamic economy. From Dutch settlement to the extraordinary diversity of today’s immigrants, the book chronicles successive waves of Irish, German, Jewish, and Italian immigrants and African American and Puerto Rican migrants, showing how immigration changes immigrants and immigrants change the city. In a compelling narrative synthesis, All the Nations Under Heaven considers the ongoing tensions between inclusion and exclusion, the pursuit of justice and the reality of inequality, and the evolving significance of race and ethnicity. In an era when immigration, inequality, and globalization are bitterly debated, this revised edition is a timely portrait of New York City through the lenses of migration and immigration.

The events of 1989 were the material of great reporting. They also revealed the power of journalism. Long before people in Central and Eastern Europe liberated themselves, they discovered democratic freedom, putting to print their own ideas and chronicling events of the day. Indeed, long before they had democracies in law, they had imagined them on paper. In the Solidarity network that produced books and leaflets and news bulletins, in the essays of Václav Havel, in the samizdat publishing house in Budapest that used a portable printing machine, Eastern Europeans demonstrated the organic link between journalism and self-government. They showed how journalism nurtures the imagination, dialogue, and honesty that are basic to democratic life. If history had ended in 1989, there would be cause for easy optimism. The changes that swept Central and Eastern Europe passed with relatively little bloodshed. But agonies of the former Yugoslavia, convulsions of the former Soviet Union, and enduring battles with censors and would-be censors bedevil emerging democracies. Not only does much remain for journalists to cover in Central and Eastern Europe, in some places there the fate of journalism is still an open question. For all these reasons, Reporting the Fall of European Communism explores, not only the events of 1989, but new stories that have emerged in Central and Eastern Europe over the past decade. This volume will be of interest to media professionals, academics and others with an interest in the power of journalism.

Bob's mind is conflicted. The left side always wants adventure while the right side develops sheer terror of what is about to happen. Karen is a non-athlete that is normally calm, but this adventure at age 65 has unsettled Karen. They could quit, but Bob has been planning this trip for over 30 years.

When bombarded with X-rays, solid materials produce distinct scattering patterns similar to fingerprints. X-ray powder diffraction is a technique used to fingerprint solid samples, which are then identified and cataloged for future use-much the way the FBI keeps fingerprints on file. The current database of some 70,000 material prints has been put to a broad range of uses, from the analysis of moon rocks to testing drugs for purity. Introduction to X-ray Powder Diffractometry fully updates the achievements in the field over the past fifteen years and provides a much-needed explanation of the state-of-the-art techniques involved in characterizing materials. It covers the latest instruments and methods, with an emphasis on the fundamentals of the diffractometer, its components, alignment, calibration, and automation. The first three chapters outline diffraction theory in clear language, accessible to both students and professionals in chemistry, physics, geology, and materials science. The book's middle chapters describe the instrumentation and procedures used in X-ray diffraction, including X-ray sources, X-ray detection, and production of monochromatic radiation. The chapter devoted to instrument design and calibration is followed by an examination of specimen preparation methods, data collection, and reduction. The final two chapters provide in-depth discussions of qualitative and quantitative analysis. While the material is presented in an orderly progression, beginning with basic concepts and moving on to more complex material, each chapter stands on its own and can be studied independently or used as a professional reference. More than 230 illustrations and tables demonstrate techniques and clarify complex material. Self-contained, timely, and user-friendly, Introduction to X-ray Powder Diffractometry is an enormously useful text and professional reference for analytical chemists, physicists, geologists and materials scientists, and upper-level undergraduate and graduate students in materials science and analytical chemistry. X-ray powder diffraction-a technique that has matured significantly in recent years-is used to identify solid samples and determine their composition by analyzing the so-called "fingerprints" they generate when X-rayed. This unique volume fulfills two major roles: it is the first textbook devoted solely to X-ray powder diffractometry, and the first up-to-date treatment of the subject in 20 years. This timely, authoritative volume features: * Clear, concise descriptions of both theory and practice-including fundamentals of diffraction theory and all aspects of the diffractometer * A treatment that reflects current trends toward automation, covering the newest instrumentation and automation techniques * Coverage of all the most common applications, with special emphasis on qualitative and quantitative analysis * An accessible presentation appropriate for both students and professionals * More than 230 tables and illustrations Introduction to X-ray Powder Diffractometry, a collaboration between two internationally known and respected experts in the field, provides invaluable guidance to anyone using X-ray powder diffractometers and diffractometry in materials science, ceramics, the pharmaceutical industry, and elsewhere.
