This introductory text develops the fundamental physics of the behavior of granular materials. It covers the basic properties of flow, friction, and fluidization of uniform granular materials; discusses mixing and segregation of heterogeneous materials (the famous "brazil-nut problem"); and concludes with an introduction to numerical models. The presentation begins with simple experiments and uses their results to build concepts and theorems about materials whose behavior is often quite counter-intuitive; presenting in a unified way the background needed to understand current work in the field. Developed for students at the University of Paris, the text will be suitable for advanced undergraduates and beginning graduates; while also being of interest to researchers and engineers just entering the field.
Splash! On a trip to the aquarium, George seets beluga whales, sea lions, a big red octopus, and of course fish everywhere!

Now with downloadable audio. AGES: 4 to 8 AUTHOR: Hans Augusto Rey was born in Hamburg, Germany in 1898. As a child, he spent much of his free time in that city's famous Hagenbeck Zoo drawing animals. After serving in the army during World War I, he studied philology and natural science at the University of Hamburg. He then married Margret Rey and they moved to Montmartre for four years. The manuscript for the first Curious George books was one of the few items the Reys carried with them on their bicycles when they escaped from Paris in 1940. Eventually, they made their way to the United States, and Curious George was published in 1941. Curious George has been published in many languages, including French, German, Japanese, Afrikaans, and Norwegian. Additional Curious George books followed, as well as such other favourites as Cecily G. and the Nine Monkeys and Find the Constellations. Colour illustrations
