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
In late February and early March of 1836, the Mexican Army under the command of General Antonio López de Santa Anna besieged a small force of Anglo and Tejano rebels at a mission known as the Alamo. The defenders of the Alamo were in an impossible situation. They knew very little of the events taking place outside the mission walls. They did not have much of an understanding of Santa Anna or of his government in Mexico City. They sent out contradictory messages, they received contradictory communications, they moved blindly and planned in the dark. And in the dark early morning of March 6, they died. In that brief, confusing, and deadly encounter, one of America's most potent symbols was born. The story of the last stand at the Alamo grew from a Texas rallying cry, to a national slogan, to a phenomenon of popular culture and presidential politics. Yet it has been a hotly contested symbol from the first. Questions remain about what really happened: Did William Travis really draw a line in the sand? Did Davy Crockett die fighting, surrounded by the bodies of two dozen of the enemy? And what of the participants' motives and purposes? Were the Texans justified in their rebellion? Were they sincere patriots making a last stand for freedom and liberty, or were they a ragtag collection of greedy men-on-the-make, washed-up politicians, and backwoods bullies, Americans bent on extending American slavery into a foreign land? The full story of the Alamo -- from the weeks and months that led up to the fateful encounter to the movies and speeches that continue to remember it today -- is a quintessential story of America's past and a fascinating window into our collective memory. In A Line in the Sand, acclaimed historians Randy Roberts and James Olson use a wealth of archival sources, including the diary of José Enrique de la Peña, along with important and little-used Mexican documents, to retell the story of the Alamo for a new generation of Americans. They explain what happened from the perspective of all parties, not just Anglo and Mexican soldiers, but also Tejano allies and bystanders. They delve anew into the mysteries of Crockett's final hours and Travis's famous rhetoric. Finally, they show how preservationists, television and movie producers, historians, and politicians have become the Alamo's major interpreters. Walt Disney, John Wayne, and scores of journalists and cultural critics have used the Alamo to contest the very meaning of America, and thereby helped us all to "remember the Alamo."

Book Description
A longtime CNN columnist astutely combines history and global politics to help us better understanding the exploding number of military, political, and diplomatic crises around the globe. The riveting and illuminating behind-the-scenes stories of the world's most intense “red lines," from diplomatic and military challenges at particular turning points in history to the ones that set the tone of geopolitics today. Whether it was the red line in Munich that led to the start of the Second World War, to the red lines in the South China Sea, the Korean Peninsula, Syria and the Middle East. As we traverse the globe, Andelman uses original documentary research, previously classified material, and interviews with key players, to help us understand the growth, the successes and frequent failures that have shaped our world today. Andelman provides not just vivid historical context, but a political anatomy of these red lines. How might their failures be prevented going forward? When and how can such lines in the sand help preserve peace rather than tempt conflict? A Red Line in the Sand is a vital examination of our present and the future—where does diplomacy end and war begin? It is an object lesson of tantamount importance to every leader, diplomat, citizen, and voter. As America establishes more red lines than it has pledged to defend, every American should understand the volatile atmosphere and the existential stakes of the red web that encompasses the globe.
