"Granular materials are composed of macroscopic particles, not molecules, and yet they can assemble in disordered configurations, such is present in glass, and they exhibit both fluid-like and solid-like behaviors. This book gives a broad introduction to granular materials, a fast-developing field that impacts most science and engineering disciplines, describing the different types and origins of grains, natural and fabricated, and explaining the physical properties of a "pile" of grains. All the physical concepts that have been investigated during the last thirty years are described and illustrated in simple terms"-- Provided by publisher

The hidden elegance in everyday objects and physical mechanisms, from crumpled paper to sandcastles. Hidden Wonders 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.
