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. Avalanches, for example, can be characterized as friction, geometric congestion between grains. Granular materials provide a model for various domains, including engineering, physics, and biology, shedding light on collective behavior in disordered settings in general. William Blake famously wished To See a World in a Grain of Sand; in this book, pioneering researchers in granular matter explain the science contained in a simple assembly of grains.\u003c\/p\u003e\u003cp\u003eThe authors begin by describing the single grain with its different origins, shapes, and sized, 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.\u003cbr\u003e\u003c\/p\u003e","brand":"WoB","offers":[{"title":"GB \/ NEW \/ GARDNERS","offer_id":49742598144273,"sku":"NGR9780262545303","price":0.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/0262545306.jpg?v=1751164906"},{"product_id":"hidden-wonders-book-etienne-guyon-9780262539890","title":"Hidden Wonders","description":"\u003cb\u003eThe hidden elegance in everyday objects and physical mechanisms, from crumpled paper to sandcastles.\u003c\/b\u003e\u003cbr\u003e \u003cbr\u003e \u003ci\u003eHidden Wonders\u003c\/i\u003e focuses on the objects that populate our everyday life--crumpled paper, woven fabric, a sand pile--but looks at them with a physicist's eye, revealing a hidden elegance in mundane physical mechanisms. In six chapters--Builders, Creating Shapes, Building with Threads, From Sand to Glass, Matter in Motion, and Fractures--the authors present brief stories, set in locales ranging from the Eiffel Tower to a sandcastle, that illustrate the little wonders hidden in the ordinary. A simple experiment that readers can perform at home concludes each story. More than 200 illustrations bring the stories to life.","brand":"WoB","offers":[{"title":"US \/ GOOD \/ SBYB","offer_id":49972556497169,"sku":"CIN0262539896G","price":0.0,"currency_code":"GBP","in_stock":false},{"title":"US \/ VERY_GOOD \/ SBYB","offer_id":50347505320209,"sku":"CIN0262539896VG","price":0.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/0262539896.jpg?v=1751101100"}],"url":"https:\/\/www.worldofbooks.com\/collections\/author-books-by-etienne-guyon.oembed","provider":"World of Books ","version":"1.0","type":"link"}
