Book Description
Explaining the science contained in a simple assembly of grains—the most abundant form of matter present on Earth. Granular media—composed of vast amounts of grains, consolidated or not—constitute the most abundant form of solid matter on Earth. Granular materials assemble in disordered configurations scientists often liken to a bag of marbles. Made of macroscopic particles rather than molecules, they defy the standard scheme of classification in terms of solid, liquid, and gas. Granular materials provide a model relevant to various domains of research, including engineering, physics, and biology. William Blake famously wished “To See a World in a Grain of Sand”; in this book, pioneering researchers in granular matter explain the science hidden behind simple grains, shedding light on collective behavior in disordered settings in general. The authors begin by describing the single grain with its different origins, shapes, and sizes, then examine grains in piled or stacked form. They explain the packing fraction of granular media, a crucial issue that bears on the properties displayed in practical applications; explore small-scale deformations in piles of disordered grains, with particular attention to friction; and present theories of various modes of disorder. Along the way, they discuss such concepts as force chains, arching effects, wet grains, sticky contacts, and inertial effects. Drawing on recent numerical simulations as well as classical concepts developed in physics and mechanics, the book offers an accessible introduction to a rapidly developing field.

Book Description
Berlin: long-celebrated as a city of artists and outcasts, but also a city of teachers and construction workers. A place of tourists and refugees, and the memories of those exiled and expelled. A city named after marshland; if you dig a hole, you'll soon hit sand. The stories of Berlin are the stories Built on Sand. A wooden town, laid waste by the Thirty Years War that became the metropolis by the Spree that spread out and swallowed villages whole. The city of Rosa Luxemburg and Joseph Roth, of student movements and punks on both sides of the Wall. A place still bearing the scars of National Socialism and the divided city that emerged from the wreckage of war. Built on Sand. centres on the personal geographies of place, and how memory and history live on in the individual and collective imagination. Stories of landscapes and a city both real and imagined; stories of exile and trauma, mythology and folklore; of how the past shapes and distorts our understanding of the present in an age of individualism, gentrification and the rising threat of nativism and far-right populism. Together, these stories offer a portrait of a city three decades on from the fall of the Berlin Wall, and the legacy of that history in a city that was once divided but remains fractured and fragmented.

Book Description
Is your faith built on the Rock or on Sand? Jesus' parable about two houses, one built on a rock and the other built on sand, has provided encouragement and warning for students of God's Word. In Phil Sanders' newest book, A Faith Built on Sand, he examines the dangers inherent in a faith that has no foundation more substantial than sand. Sanders confronts such current movements and positions as society's influence on Christianity, cultural morality, tolerance, the emerging church and synthetic Christianity. He explores the flaws evident in each of these when compared with God's inspired Word. He insists the only viable solution to this sand-based faith is finding your way back to the cross.

Book Description
Oscillations in opium poppy production in Afghanistan have long been associated with how the state was perceived, such as after the Taliban imposed a cultivation ban in 2000-1. The international community's subsequent attempts to regulate opium poppy became intimately linked with its own state-building project, and rising levels of cultivation were cited as evidence of failure by those international donors who spearheaded development in poppy-growing provinces like Helmand, Nangarhar and Kandahar. Mansfield's book examines why drug control - particularly opium bans - have been imposed in Afghanistan; he documents the actors involved; and he scrutinizes how prohibition served divergent and competing interests. Drawing on almost two decades of fieldwork in rural areas, he explains how these bans affected farming communities, and how prohibition endured in some areas while in others opium production bans undermined livelihoods and destabilized the political order, fuelling violence and rural rebellion. Above all this book challenges how we have come to understand political power in rural Afghanistan. Far from being the passive recipients of violence by state and non-state actors, Mansfield highlights the role that rural communities have played in shaping the political terrain, including establishing the conditions under which they could persist with opium production.

Book Description
Jesus: His Story in Stone is a reflection on still-existing stone objects that Jesus would have known, seen, or even touched. Each of the seventy short chapters is accompanied by a photograph taken on location in Israel. Arranged chronologically, the one-page meditations compose a portrait of Christ as seen through the significant stones in His life, from the cave where He was born to the rock of Calvary. While packed with historical and archaeological detail, the book’s main thrust is devotional, leading the reader both spiritually and physically closer to Jesus.

Book Description
Cultural critics say that "science is politics by other means," arguing that the results of scientific inquiry are profoundly shaped by the ideological agendas of powerful elites. They base their claims on historical case studies purporting to show the systematic intrusion of sexist, racist, capitalist, colonialist and/or professional interests into the very content of science. Physicist Alan Sokal recently poked fun at these claims by foisting a sly parody of the genre on the unwitting editors of the cultural studies journal Social Text touching off a still unabated torrent of editorials, articles, and heated classroom and Internet discussion. This hard-hitting collection picks up where Sokal left off. The essayists offer crisp and detailed critiques of case studies offered by the cultural critics as evidence that scientific results tell us more about social context than they do about the natural world. Pulling no punches, they identify numerous crude factual blunders (e.g. that Newton never performed any experiments) and egregious errors of emission, such as the attempt to explain the slow development of fluid dynamics solely in terms of gender bias. Where there are positive aspects of a flawed account, or something to be learned from it, they do not hesitate to say so. Their target is shoddy scholarship. Comprising new essays by distinguished scholars of history, philosophy, and science (including Sokal himself), this book raises a lively debate to a new level of seriousness.

Book Description
A finalist for the PEN/E. O. Wilson Literary Science Writing Award The gripping story of the most important overlooked commodity in the world--sand--and the crucial role it plays in our lives. After water and air, sand is the natural resource that we consume more than any other--even more than oil. Every concrete building and paved road on Earth, every computer screen and silicon chip, is made from sand. From Egypt's pyramids to the Hubble telescope, from the world's tallest skyscraper to the sidewalk below it, from Chartres' stained-glass windows to your iPhone, sand shelters us, empowers us, engages us, and inspires us. It's the ingredient that makes possible our cities, our science, our lives--and our future. And, incredibly, we're running out of it. The World in a Grain is the compelling true story of the hugely important and diminishing natural resource that grows more essential every day, and of the people who mine it, sell it, build with it--and sometimes, even kill for it. It's also a provocative examination of the serious human and environmental costs incurred by our dependence on sand, which has received little public attention. Not all sand is created equal: Some of the easiest sand to get to is the least useful. Award-winning journalist Vince Beiser delves deep into this world, taking readers on a journey across the globe, from the United States to remote corners of India, China, and Dubai to explain why sand is so crucial to modern life. Along the way, readers encounter world-changing innovators, island-building entrepreneurs, desert fighters, and murderous sand pirates. The result is an entertaining and eye-opening work, one that is both unexpected and involving, rippling with fascinating detail and filled with surprising characters.
